People suffering from severe monothematic delusions, such as Capgras, Fregoli, or Cotard patients, regularly assert extraordinary and unlikely things. For example, some say that their loved ones have been replaced by impostors. A popular view in philosophy and cognitive science is that such monothematic delusions aren't beliefs because they don't guide behaviour and affect in the way that beliefs do. Or, if they are beliefs, they are somehow anomalous, atypical, or marginal beliefs. We present evidence from five studies that folk (...) psychology unambiguously views monothematic delusions as stereotypical beliefs. This calls into question widespread assumptions in the professional literature about belief's stereotypical functional profile. We also show that folk psychology views delusional patients as holding contradictory beliefs. And we show that frequent assertion is a powerful cue to belief ascription, more powerful than even a robust and consistent track record of non-verbal behaviour. (shrink)

Retrieval Induced Forgetting refers to the finding that the retrieval of some items from memory impairs the retrieval of related items. The RIF effect is indicated by a comparison of RP- with unrelated but also tobe- remembered items. Since RIF appears during intentional memorizing of words, therefore we checked whether it depends on attentional control involved in goal maintenance, and also if implicit evaluations of to-be-remembered contents moderate this process. In three experiments, each including AC as the independent variable, we (...) found AC to be related to the RIF effect. Only high but not low AC subjects showed the presence of RIF. The results of the affective priming procedure showed that implicit evaluations of NRP items moderate the relationship of high AC and the RIF effect. The explanation why temporarily devaluated NRP could enhance the RIF effect and suggestion concerning future research summarize the article. (shrink)

The paper delineates a study of executive functions, construed as procedural working memory, from a motivational perspective. Since WM theories and motivation theories are both concerned with purposive activity, the role of implicit evaluations observed in goal pursuit can be anticipated to arise also in the context of cognitive control, e.g., during the performance of the Stroop task. The role of positive and negative affect in goal pursuit consists in controlling attention resources according to the goal and situational requirements. Positive (...) affect serves to maintain goals and means in the scope of attention, whereas negative affect activates the inhibition of non-functional contents, e.g., distractors and irrelevant objects. Adaptation to conflict proceeds via sequential triggering of negative and positive affect. Moreover, it was demonstrated that the focus on action or reflection changes the scope of contents subjected to implicit control. Therefore, I suggest that the motivational system, to a large extent, plays the role of the Central Executive. The paper opens a discussion and proposes studies on affective mechanisms of cognitive control. (shrink)

Cognitive science is the interdisciplinary investigation of mind and intelligence, embracing psychology, neuroscience, anthropology, artificial intelligence, and philosophy. There are many important philosophical questions related to this investigation, but this short chapter will focus on the following three. What is the nature of the explanations and theories developed in cognitive science? What are the relations among the five disciplines that comprise cognitive science? What are the implications of cognitive science research for general issues in the philosophy of science? I will (...) argue that cognitive theories and explanations depend on representations of mechanisms and that the relations among the five disciplines, especially psychology and neuroscience, depend on relations between kinds of mechanisms. These conclusions have implications for central problems in general philosophy of science such as the nature of theories, explanations, and reduction between theories at different levels. (shrink)
