The purpose of this paper is to propose a refinement of the notion of innateness. If we merely identify innateness with bias, then we obtain a poor characterisation of this notion, since any learning device relies on a bias that makes it choose a given hypothesis instead of another. We show that our intuition of innateness is better captured by a characteristic of bias, related to isotropy. Gen...

We describe two different cognitive process models of a well known experiment on social influence (Salganik, Dodds, & Watts, 2006). One model, the social influence model, reproduced the choices that participants took by modeling both the cognitive processes the participant engaged in and the social influences that the participant saw. The second model, the pure cognitive model, used only cognit...

The standard approach to Bayesian models of Cognition (also known as rational models) requires researchers to make strong assumptions about people’s prior beliefs. For example, it is often assumed that people’s subjective knowledge is best represented by “true” environmental data. We show that an integrative Bayesian approach—combining Bayesian cognitive models with Bayesian data analysis—allow...

The contents of perceptual experience, it has been argued, often include a characteristic “non-conceptual” component (Evans, 1982). Rejecting such views, McDowell (1994) claims that such contents are conceptual in every respect. It will be shown that this debate is compromised by the failure of both sides to mark a further, and crucial, distinction in cognitive space. This is the distinction be...

Instruments like the piano or guitar have a long tradition in many cultures such that non-musicians who encounter them understand that the piano keys can be pressed and the guitar strings can be plucked. Users of computer-based sound synthesis tools must use parameter names and interface feedback to develop a model of the available sound space of the instrument. Not all users may attribute the ...

We used a survey design to compare three social cognitive models in their ability to explain intentions of precautionary online behaviour. The models were protection motivation theory (PMT), the reasoned action approach (RAA) and an integrated model comprising variables of these models. Data from 1,200 Dutch users of online banking were analysed with partial-leastsquares path-modelling. The two...

The basic technique of problem-solving is structurization of knowledge about object and its environment and construction of a cognitive model. The technique includes monitoring of dynamics of factors of the model (their tendencies), analysis of the model structure with the use of SWOT-approach, and modeling that permits to determine and solve semi-structured problems. The technique allows suppo...

This article provides a three-way interaction between experiments, logic and cognitive modelling so as to bring out a shared perspective among these diverse areas, aiming towards better understanding and better modelling of human strategic reasoning in dynamic games.

RAM Laboratories is developing a distributed agentbased toolbox known as the Course of Action Analysis with Radio Effects Toolbox (CARET). The purpose of this toolbox is to provide agent driven simulation and cognitive modeling capabilities that enable improved analyses and diagnoses of network behavior within a mission context. This paper presents current developments during the second phase C...
