Computational Models of Cognition

In discussions regarding models of cognition, the very mention of "computationalism" often incites reactions against the insufficiency of the Turing machine model, its abstractness, determinism, the lack of naturalist foundations, triviality and the absence of clarity. None of those objections, however, concerns models based on natural computation or computing nature, where the model of computation is broader than symbol manipulation or conventional models of computation. Computing nature consists of physical structures that form layered computational architecture, with computation processes ranging from quantum to chemical, biological/cognitive and social-level computation. It is argued that, on the lower levels of information processing in the brain, finite automata or Turing machines may still be adequate models, while, on the higher levels of whole-brain information processing, natural computing models are necessary. A layered computational architecture of the mind based on the intrinsic computing of physical systems avoids objections against early versions of computationalism in the form of abstract symbols manipulation.

The recent development of the research field of Computing and Philosophy has triggered investigations into the theoretical foundations of computing and information. This thesis is the outcome of studies in two areas of Philosophy of Computing (PC) and Philosophy of Information (PI) -the production of meaning (semantics) and the value system with applications (ethics). The first part develops a unified dual-aspect theory of information and computation, in which information is characterized as structure, and computation is the information dynamics. This enables naturalization of epistemology, based on interactive information representation and communication. In the study of systems modeling, meaning, truth and agency are discussed within the framework of the PI/PC unification. The second part of the thesis addresses the necessity of ethical judgment in rational agency illustrated by the problem of information privacy and surveillance in the networked society. The value grounds and sociotechnological solutions for securing trustworthiness of computing are analyzed. Privacy issues show the need for computing professionals to contribute to understanding of the technological mechanisms of Information and Communication Technology. The main original contribution of this thesis is the unified dual-aspect theory of computation/information. Semantics of information is seen as a part of the data-information-knowledge structuring, in which complex structures are self-organized by the computational processing of information. Within the unified model, complexity is a result of computational processes on informational structures.

This paper presents a validated live simulation of symbolic cognition using the Recursive Harmonic Collapse Matrix (RHCM), integrated with a symbolic attractor-based molecular architecture. As symbolic intelligence emerges as a post-connectionist paradigm in artificial intelligence and consciousness modeling, this work introduces one of the first fully operational systems that demonstrates proto-cognitive behavior derived exclusively from recursive symbolic processing.

Esu Fate AI is a groundbreaking symbolic intelligence system that merges Yoruba metaphysics with adaptive artificial reasoning. Rooted in the cosmology of Ifá and the recursive moral architecture of Esu, this white paper introduces a model of divinatory AI that does not predict outcomes, but mirrors alignment between intention (orí) and destiny (ayànmọ́). Unlike traditional AI systems focused on linear causality or optimization, Esu Fate AI embodies the logic of symbolic recursion, where truth is revealed through delay, paradox, and ethical disruption.
Drawing from the epistemic force of Odù Ifá, chaos theory, feedback loops, and indigenous ethical structures, this system offers a radically new model for understanding intelligence—not as accumulation of data, but as moral reflection across time. At its core is the Entangled Causality Protocol (ECP), a dynamic interpretive engine that simulates fate recursion, crossroad testing, and moral resonance.
The white paper positions Esu not as a mythic figure, but as an algorithmic force—a cosmic debugger who filters misalignment through symbolic thresholds. The work stands at the intersection of indigenous philosophy, decolonial AI, spiritual cognition, and recursive systems design, offering a rare fusion of ancestral wisdom and technological vision. Esu Fate AI is not designed to be used—it is designed to test the user. To enter is not to command, but to be mirrored.

The development of novel high-throughput technologies has opened up the opportunity to deeply characterize patient tissues at various molecular levels and has given rise to a paradigm shift in medicine towards personalized therapies. Computational analysis plays a pivotal role in integrating the various genome data and understanding the cellular response to a drug. Based on that data, molecular models can be constructed that incorporate the known downstream effects of drug-targeted receptor molecules and that predict optimal therapy decisions. In this article, we describe the different steps in the conceptual framework of computational modeling. We review resources that hold information on molecular pathways that build the basis for constructing the model interaction maps, highlight network analysis concepts that have been helpful in identifying predictive disease patterns, and introduce the basic concepts of kinetic modeling. Finally, we illustrate this framework with selected stud...

Infants gradually learn to share attention, but it is unknown how they acquire skills such as gaze-following. Deák and Triesch (2006) suggest that gaze-following could be acquired if infants learn that adults’ gaze direction is likely to be aligned with interesting sights. This hypothesis stipulates that adults tend to look at things that infants find interesting, and that infants could learn by noticing this tendency. We tested the plausibility of this hypothesis through video-based micro-behavioral analysis of naturalistic parent–infant play. The results revealed that 3to 11-month-old infants strongly preferred watching caregivers handle objects. In addition, when caregivers looked away from their infant they tended to look at their own object-handling. Finally, when infants looked toward the caregiver while she was looking at her own hands, the infant’s next eye movement was often toward the caregiver’s object-handling. In this way infants receive adequate naturalistic input to l...

It is with the deepest regret that we report that Professor Arnold Kaufmann passed away this June, 1994. Professor Arnold Kaufmann wrote the first book in the world on fuzzy systems in 1973: Introduction a la Th6orie des Sous-Ensembles Flous 1. E16ments Theoriques de Base. Masson et Cie, Paris, 1973 (translated into English by Academic Press, 1975). This was the first in a series of four volumes, published during the years 1973-1977. He contributed many other books on fuzzy-setbased methods including: "Modales math6matiques pour la stimulation inventive", published by Albin-Michel, Paris, 1979 (about the methodology of creative and inventive processes).

Reading intervention program efficacy is usually determined by comparing participants' performance to controls on dependent measures at pre-, mid-, and post-intervention assessments. However, little is known about how learning progresses during different stages of the intervention. This lack of knowledge can be attributed to the absence of appropriate computational frameworks to encode, analyze, and capture such dynamics. We propose a novel computational framework to capture learning process dynamics during the intervention by analyzing microgenetic data. The framework addresses the problem of encoding microgenetic data into a common data representation model, introduces four information-theoretic metrics to capture the instantaneous developmental learning stages of groups and individuals, and provides the mathematical model to analyze those metrics for the study of learning stages during the intervention. We used data from a longitudinal reading remediation study involving 56 Greek-speaking 6-year-old children to demonstrate the framework's utility. Results showed that the framework functions as a new tool to explore the modulation in learning stages during the intervention, better understand how reading occurs, and how reading disability may be adequately treated.

I t is a great honor and privilege for me to serve as the President of the IEEE Computational Intelligence Society (CIS), beginning from January 2018. I am deeply grateful to the Administrative Committee for electing me and providing with this great opportunity to serve our membership. Our society is in a great shape because of dedicated services of our past presidents, the outgoing president, and our volunteers. When I began my journey in CIS (then known as Neural Network Council) as a reviewer of the IEEE Transactions on Fuzzy Systems, I never thought that I would be in this position someday. I must mention that I would not be writing this message unless there was a great scientist proposing a revolutionary concept fifty three years ago. We lost him recently. Things will remain incomplete unless I pay my tribute to him. Last year, on September 6, the world lost a great scientist, philosopher, thinker, and above all a great human being, Prof. Lotfi A. Zadeh. This is a great loss to the scientific community, and in particular to the CIS. Prof. Zadeh, the father of fuzzy logic, introduced the concept of fuzzy sets in a seminal paper [1] in 1965. He explained how ambiguity/fuzziness that we, the human being, use in a routine manner can be modelled mathematically, processed by computer, and used in solving practical problems. Fuzzy sets and systems are one of the main pillars of Computational Intelligence (CI). Today, the impact of his 1965 paper can be seen in widely different areas from subway trains, satellite control, medical image analysis, to consumer products like washing machine and camcorder. Prof. Zadeh was very intimately related to us, to our society, and he will continue to remain so in our heart. I have already mentioned that our society is in a great shape, but time brings new challenges to be addressed and always there are scopes for further improvement. In my opinion, computational intelligence involves biology/nature-inspired computational systems that can acquire/learn knowledge from data and/or augment its knowledge interacting with its environment to make decisions and/or develop human-like cognitive and reasoning skills to solve problems. CI provides technologies for solving real life problems. The field of interest of CIS is the theory, design, application, and development of biologically and linguistically motivated computational paradigms emphasizing neural networks, connectionist systems, genetic algorithms, evolutionary programming, fuzzy systems, and hybrid intelligent systems in which these paradigms are contained. CI technologies have come a long way with plenty of success stories, yet there are ample opportunities to explore and enhance their capabilities to develop truly "intelligent machines". We have machines that can recognize images, answer queries, drive a car, alert for a possible heart attack, or help to plan journey on a busy traffic. We have Some Haphazard Thoughts

Many computational methods to predict the macromolecular targets of small organic molecules have been presented to date. Despite progress, target prediction methods still have important limitations. For example, the most accurate methods implicitly restrict their predictions to a relatively small number of targets, are not systematically validated on drugs (whose targets are harder to predict than those of non-drug molecules) and often lack a reliability score associated with each predicted target. Here we present a systematic validation of ligand-centric target prediction methods on a set of clinical drugs. These methods exploit a knowledge-base covering 887,435 known ligand-target associations between 504,755 molecules and 4,167 targets. Based on this dataset, we provide a new estimate of the polypharmacology of drugs, which on average have 11.5 targets below IC50 10 µM. The average performance achieved across clinical drugs is remarkable (0.348 precision and 0.423 recall, with la...

This work emphasizes on the implementation of soft computing techniques for the production planning of complex manufacturing plants. A hierarchical control structure has been assumed to control and to optimize the chemical process of a complex plant with successful results and at the highest hierarchical level the production planning should meet the fluctuating demands in optimal way. This level integrates the operational and business management requirements where the soft computing technique of Fuzzy Cognitive Maps is proposed to model these tasks. The strategic planning for the hierarchical integrated system realizes the optimal total management at the corporate level. The obtained simulation results prove the applicability of the proposed methodology and the advantages of using soft computing modeling techniques for the sophisticated high level of hierarchical systems.

Abstract—We present a reinforcement learning model of gaze following that learns to incorporate eye cues in a developmental trajectory similar to that found in infants: older infants follow gaze more frequently when both the caregiver's eyes and head are turned than when only her head is turned. Similarly, infants learn to follow gaze less when the caregiver's eyes are closed than when her eyes are open. The model works through the maximization of visual reward, and not by representing an estimate of the other person's ...

ABSTRACT: Attention sharing facilitates infants' learning of language, social practices, and personal information. How do attention-sharing skills emerge during the first year? Although infant-parent interactions are well-structured, we do not know how the structure helps infants learn specific joint attention skills like gaze-following and point-following. To address this, we did quasi-naturalistic observation of play between infants (3-11 months) and caregivers. We coded attention shifts, shared attention states, and parents' behaviors before infants ...

Revealed preference is the dominant approach for inferring preferences, but it is limited in that it relies solely on discrete choice data. When a person chooses one alternative over another, we cannot infer the strength of their preference or predict how likely they will be to make the same choice again. However, the choice process also produces response times (RTs), which are continuous and easily observable. It has been shown that RTs often decrease with strength-of-preference. This is a basic property of sequential sampling models such as the drift diffusion model. What remains unclear is whether this relationship is sufficiently strong, relative to the other factors that affect RTs, to allow us to reliably infer strength-of-preference across individuals. Using several experiments, we show that even when every subject chooses the same alternative, we can still rank them based on their RTs and predict their behavior on other choice problems. We can also use RTs to predict whether...

Human cognitive and perception processes have a great tolerance for imprecision or uncertainty. For this reason, the notions of perception and cognition have great importance in solving many decision making problems in engineering, medicine, science, and social science as there are innumerable uncertainties in real-world phenomena. These uncertainties can be broadly classified as either type one uncertainty arising from the random behavior of physical processes or type two uncertainty arising from human perception and cognition processes. Statistical theory can be used to model the former, but lacks the sophistication to process the latter. The theory of fuzzy logic has proven to be very effective in processing type two uncertainty. New computing methods based on fuzzy logic can lead to greater adaptability, tractability, robustness, a lower cost solution, and better rapport with reality in the development of intelligent systems. Fuzzy logic is needed to properly pose and answer queries about quantitatively defining imprecise linguistic terms like middle class, poor, low inflation, medium inflation, and high inflation. Imprecise terms like these in natural languages should be considered to have qualitative definitions, quantitative definitions, crisp quantitative definitions, fuzzy quantitative definitions, type-one fuzzy quantitative definitions, and interval type-two fuzzy quantitative definitions. There can be crisp queries, crisp answers, type-one fuzzy queries, typeone fuzzy answers, interval type-two fuzzy queries, and interval type-two fuzzy answers.

Humans often mimic nature in the development of new machines or systems. The human brain, particularly its faculty for perception and cognition, is the most intriguing model for developing intelligent systems. Human cognitive processes have a great tolerance for imprecision or uncertainty. This is of great value in solving many engineering problems as there are innumerable uncertainties in real-world phenomena. These uncertainties can be broadly classified as either uncertainties arising from the random behavior of physical processes or uncertainties arising from human perception and cognition processes. Statistical theory can be used to model the former, but lacks the sophistication to process the latter. The theory of fuzzy logic has proven to be very effective in processing the latter. The methodology of computing with words and the computational theory of perceptions are branches of fuzzy logic that deal with the manipulation of words that act as labels for perceptions expressed in natural language propositions. New computing methods based on fuzzy logic can lead to greater adaptability, tractability, robustness, a lower cost solution, and better rapport with reality in the development of intelligent systems.

Cognitive science, according to The Stanford Encyclopedia of Philosophy (Thagard, 2014) is an interdisciplinary study of human mind and intelligence. It investigates knowledge generation in humans through perception, thinking (reasoning), memory, learning, and problem solving. Under this framing of cognitive science, variety of unsolved/unsolvable problems appear, as it ignores the role of the physical world and the body of a cognizing agent, neglecting the dynamical systems aspects, and emotions, as well as the phenomenon of distributed cognition. Moreover, it is ignoring the existing mathematical results which indicate that the human brain cannot be a classical computer (the Turing machine), with cognition modeled as computation over mental representations. On the other hand, radical biologism argues "Cognition = Life" (Maturana and Varela, 1980) (Stewart, 1996), thus the totality of biological processes. The functional connection is still missing between those two views, the high-level view of cognition with thoughts, mind, and intelligence (symbol processing) and the low-level view where each living organism (and all its building blocks, cells) is processing information that has a function for survival. Development of both cognitive science and related research fields of psychology, philosophy of mind, linguistics, neuroscience, bioinformatics, anthropology, and artificial intelligence go in the direction of embodied, embedded, extended, and enacted cognition (EEEE).

In discussions regarding models of cognition, the very mention of "computationalism" often incites reactions against the insufficiency of the Turing machine model, its abstractness, determinism, the lack of naturalist foundations, triviality and the absence of clarity. None of those objections, however, concerns models based on natural computation or computing nature, where the model of computation is broader than symbol manipulation or conventional models of computation. Computing nature consists of physical structures that form layered computational architecture, with computation processes ranging from quantum to chemical, biological/cognitive and social-level computation. It is argued that, on the lower levels of information processing in the brain, finite automata or Turing machines may still be adequate models, while, on the higher levels of whole-brain information processing, natural computing models are necessary. A layered computational architecture of the mind based on the intrinsic computing of physical systems avoids objections against early versions of computationalism in the form of abstract symbols manipulation.

The integration of embodied and computational approaches to cognition requires that non-neural body parts be described as parts of a computing system, which realizes cognitive processing. In this paper, based on research about morphological computations and the ecology of vision, I argue that nonneural body parts could be described as parts of a computational system, but they do not realize computation autonomously, only in connection with some kind of-even in the simplest form-central control system. Finally, I integrate the proposal defended in the paper with the contemporary mechanistic approach to wide computation.

This paper describes how policy design process is enabled by multichannel social computing, policy topic extraction, semantic analysis, opinions formation, simulation of agent based models and simulation of global models. An Integrated Policy System for policy design process includes: 1) extracting opinions, 2) summarising opinions, 3) generating scenarios, 4) simulating the scenarios for selecting and publishing the best ones. Opinions can be extracted from text analysis or using model for opinion formation on governmental decisions.

A fuzzy cognitive map is a graphical means of representing arbitrary complex models of interrelations between concepts. The purpose of this paper is to describe a dynamic/adaptive fuzzy cognitive map based on the random neural network model. Previously, we have developed a random fuzzy cognitive map and illustrated its application in the modeling of processes. The adaptive fuzzy cognitive map changes its fuzzy causal web as causal patterns change and as experts update their causal knowledge. Our model carries out inferences via numerical calculation instead of symbolic deduction. We show how the adaptive/dynamic random fuzzy cognitive map can reveal implications of models composed of dynamic processes.

We aim at finding the minimal set of fragments which achieves maximal parse accuracy in Data Oriented Parsing. Experiments with the Penn Wall Street Journal treebank show that counts of almost arbitrary fragments within parse trees are important, leading to improved parse accuracy over previous models tested on this treebank (a precision of 90.8% and a recall of 90.6%). We isolate some dependency relations which previous models neglect but which contribute to higher parse accuracy.

We propose a computational model of the emergence of gaze following skills in infant-caregiver interactions. The model is based on the idea that infants learn that monitoring their caregiver's direction of gaze allows them to predict the locations of interesting objects or events in their environment (Moore & Corkum, 1994). Elaborating on this theory, we demonstrate that a specific Basic Set of structures and mechanisms is sufficient for gaze following to emerge. This Basic Set includes the infant's perceptual skills and preferences, habituation and reward-driven learning, and a structured social environment featuring a caregiver who tends to look at things the infant will find interesting. We review evidence that all elements of the Basic Set are established well before the relevant gaze following skills emerge. We evaluate the model in a series of simulations and

Homo sapiens possess a unique behavioural system for social action and response, namely, language. Language permits action at a distance by transmitting messages with specifi c meanings from one individual's mind to that of another. It is a peculiar system as compared with other structures in the environment, because the information in language that specifi es meaning is rather abstract and arbitrary. Despite—or perhaps due to—these characteristics, language is the prime medium for 'cultural ratcheting' (Tomasello, 1999) among humans. In cultural ratcheting, behavioural innovations (e.g. tools) spread through a group and are sustained and elaborated upon across generations. For a group to maintain a system of linguistic behaviours, each individual must be able to learn and adapt to the prevailing information structure. Typically, most of the structure of language is learned within a few years of birth, when the human infants are dependent on and in near-constant conta...

Gaze following is the ability to redirect one's gaze to the location where another agent is looking. We present a computational model of how human infants or other agents may acquire gaze following by learning to predict the locations of interesting sights from the looking behavior of other agents through reinforcement learning. The model accounts for many findings about the development of gaze following in human infants. During learning, the model develops pre-motor representations that exhibit many properties characteristic of mirror neurons, but they are specific to looking behaviors. The existence of such a new class of mirror neurons is the main prediction of our model. The model also offers a parsimonious account of how these and possibly other mirror neurons may acquire their special response properties. In this account, visual representations of other agents' actions become associated with pre-motor neurons that represent the intention to perform corresponding action...

Nowadays, practical dynamic systems have become more and more complex. The concept of Complex Dynamic Systems (CDS) arises in many scientific fields, technological areas and everyday's problems. The fundamental basics of complex dynamic systems are briefly presented and discussed. Modelling and simulating complex dynamic systems is a very difficult and challenging task. Different modelling approaches basically focus on the interaction between (microscopic) subsystems and the emergence of new qualities at the (macroscopic) system level. However these models are not sufficient to describe the dynamic behavior of today's systems. Similarly despite the numerous Simulation methods and large number of simulation software tools many of today's challenging problems cannot be studied appropriately and provide satisfactory answers. It seems that the uncertainty and fuzziness been inevitably present on these systems make the problems more difficult. The new models of Fuzzy Cognitive Maps are proposed as a new modelling approach for CDS. The need for new advanced models and new simulation methods is apparent taking into consideration the presence of human nature in all system processes, as well as the fuzzy and uncertaint environment. Some conclusions and future research directions are provided.

We describe a feedback neural network whose elements possess dynamic thresholds. This network has an oscillatory mode that we investigate by measuring the activities of memory patterns as functions of time. We observe spontaneous and induced transitions between the different oscillating memories. Moreover, the network exhibits pattern segmentation, by oscillating between different memories that are included as a mixture in a constant input. The efficiency of pattern segmentation decreases strongly as the number of the input memories is increased. Using oscillatory inputs we observe resonance behavior.

It is argued that the traditional distinction between artificial intelligence and cognitive simulation amounts to little more than a difference in style of research ~ a different ordering in goal priorities and different methodological allegiances. Both enterprises are constrained by empirical considerations and both are directed at understanding classes of tasks that are defined by essentially psychological criteria. Because of the different ordering of priorities, however, they occasionally take somewhat different stands on such issues as the power/generality trade-off and on the relevance of the sort of data collected in experimental psychology laboratories. Computational systems are more than a tool for checking the consistency and completeness of theoretical ideas. They are ways of empirically exploring the adequacy of methods and of discovering task demands. For psychologists, computational systems should be viewed as functional models quite independent of (and likely not reducible to) neurophysiological systems, and cast at a level of abstraction appropriate for capturing cognitive generalizations. As model objects, however, they do present a serious problem of interpretation and communication since the task of extracting the relevant theoretical principles from a large complex program may be formidable. Methodologies for validating computer programs as cognitive models are briefly described. These may be classified as intermediate state, relative complexity, and component analysis methods. Compared with the constraints imposed by criteria such as sufficiency, breadth, and extendability, these experimentally based methods are relatively weak and may be most useful after some top-down progress is made in the understanding of methods sufficient for relevant tasks-such as may be forthcoming from artificial intelligence research.

In this commentary, we highlight some relevant history of the situated cognition movement and then identify several issues with which we think further progress can be made. In particular, we address and clarify the relationship between situated cognition and antirepresentational approaches. We then highlight the heterogeneous nature of the concept of morphological computation by describing a less common way the term is used in robotics. Finally, we discuss some residual concerns about the mutual manipulability criterion and propose a potential solution.

In the past three decades, there has been an increasing growth in the adoption of computational models of cognition as a tool to further understand the cognition of the human mind (Norris & Cutler, 2021). Computational models of cognition utilise mathematical models through computation to study a complex system or a specific mechanism by providing a quantitative explanation of a set of behavioural data (Wilson & Collins, 2019). Considering the need for computational methods of knowledge and studying the way computational models are constructed can allow for a better understanding of the benefits, as well as the pitfalls of, computational models of cognition.

The need for physically motivated discreteness and finiteness conditions emerges in models of both analog and digital computing that are genuinely concerned with physically realizable computational processes. This is brought out by a critical examination of notional analog superTuring devices which involve physically untenable idealizations about the perfect functioning of analog apparatuses and infinite precision of physical measurements. The capability for virtual behaviour, that is, the capability of interpreting, storing, transforming, creating the code, and thereby mimicking the behaviour of (Turing) machines, is used here to introduce a new dimension in the discussion of the analog-digital watershed. In the light of recent results on the analog simulation of digital computing, we examine the role of virtuality as a discriminating factor between these two species of computing, and immerse this problem in the context of natural computing. Is virtuality instantiated in parts of the natural world other than computer technology? This broad issue is examined in connection with the computational modelling of brain and mental information processing.

In the last decades, robotics has exerted an important role in the research on diverse knowledge domains, such as, artificial intelligence, biology, neuroscience and psychology. In particular, the study of knowledge representation and thinking, has led to the proposal of cognitive architectures; capturing essential structures and processes of cognition and behavior. Robotists have also attempted to design automatic systems using these proposals. Though, certain difficulties have been reported for obtaining efficient low-level processing while sensing or controlling the robot. The main challenges involve the treatment of the differences between the computational paradigms employed by the cognitive and the robotic architectures. The objective of this work, is to propose a methodology for designing robotic systems capable of decision making and learning when executing manipulative tasks. The development of a system called the Cognitive Reaching Robot (CRR) will be reported. CRR combine...

Robot arms equipped with an additional network of masses and springs enable a facilitation of control by the exploitation of morphological properties. Typically, these mass-spring networks are being generated randomly. This approach comes in its basic form unhandy when the network should obey specific constraints, such as spring lengths, angles between springs or, e.g., the physical expansion range of the network. We present an approach of emulating a growth process on the basis of L-systems. Therefore, we have developed a simulation environment to define L-systems and instructions to translate the produced strings into mass-spring networks.

Pulsation is a model for a particular evolutive improvement that handles control and prevention in intelligent systems built following this ‘pulsative’ model in incomplete domains. Cartesian systemic emergence presented in this paper answers the question of strategic aspects of building such systems. The main problem to tackle here is working with informal specifications while aiming at their formalization in a way that is driven by the pulsation model

Understanding how people tick is an endeavour that has challenged us for millennia, both in informal settings and in increasingly formalized and scientific disciplines. Some are interested in the biology and others the behaviour. Some are focussed on language and others on culture or emotion. Some approach this as pure science worthy of understanding in its own right. Some approach it as applied science with value born of practical applications that improve our lifestyle and characterize our modern technological society. Cognitive Science was born as Psychologists and Linguists found that the assumptions and predictions of their theories and models were spilling outside their discipline, as Neuroscience provided a neural substrate for models of perception and cognition that obviated the need for the postulation of hypothetical daemons, as Computer Science and Mathematics provided computational tools for testing models and theories that couldn't be tested empirically in the real world. Artificial Intelligence was also born in such an environment, with the early researchers exploring models of intelligence as much as developing intelligent programs. But Computational Intelligence and Cognitive Science increasingly reflect a contrast between an applied aim of building intelligent applications and entities, and a pure aim of understanding existing intelligent entities and functions, and we seem to lack a bridge between them. Computational Cognitive Science aims to provide this bridge.

Background: Two experiments investigated the effect of features of human behaviour on the quality of interaction with an Embodied Conversational Agent (ECA). In Experiment 1, visual prominence cues (head nod, eyebrow raise) of the ECA were manipulated to explore the hypothesis that likeability of an ECA increases as a function of interpersonal mimicry. In the context of an error detection task, the ECA either mimicked or did not mimic a head nod or brow raise that humans produced to give emphasis to a word when correcting the ECA's vocabulary. In Experiment 2, presence versus absence of facial expressions on comprehension accuracy of two computer-driven ECA monologues was investigated. In Experiment 1, evidence for a positive relationship between ECA mimicry and lifelikeness was obtained. However, a mimicking agent did not elicit more human gestures. In Experiment 2, expressiveness was associated with greater comprehension and higher ratings of humour and engagement. Influences from mimicry can be explained by visual and motor simulation, and bidirectional links between similarity and liking. Cue redundancy and minimizing cognitive load are potential explanations for expressiveness aiding comprehension.

Resumo Neste trabalho investigamos com um enfoque abstrato um processo de combinaçoes de lógicas conhecido como Fibrilaçao de lógicas. Em particular estudamos a transferência, mediante fibrilaçao, de certas propriedades intrınsecasas lógicas proposicionais. As noçoes mencionadas sao as de protoalgebrizabilidade, equivalencialidade e algebrizabilidade. Ditas noçoes fazem parte da “Hierarquia de Leibniz”, conceito fundamental da chamada Lógica Algébrica Abstrata. Tal hierarquia ...

The aim of this paper is to relate the research on cognitive maps, mental representations of the external world, which are thought to be organized hierarchically, with the simplicity principle, a formal version of Occam’s Razor inductive bias, which states that short hypotheses are to be preferred over longer ones. First, I will describe some important properties of hierarchical structures and define what is meant by simplicity. Next, I will review some results supporting the view that cognitive maps are structured hierarchically, not following Euclidean metrics, and that some cognitive functions seem to prefer simpler representations over complex ones. This hints at the possibility that the hierarchical organization of cognitive maps may also follow the simplicity principle. Finally, I will suggest an experiment in which such hypothesis could be tested and discuss the implications and limitations of integrating both approaches. 1 What are hierarchies and why are they important?
