Do connectionist and dynamic-systems models converge on a unified theory? The answer depends on the kind of mechanism that the two models attempt to unravel. Two views of mechanism avail themselves to contemporary scientists. One view of mechanism represents cognitive activity as reducible to a cognitive architecture of separate cognitive components. Another view sees cognitive activity as emer...

Three studies tested the relationship between political extremism and cognitive complexity in an adult sample (N = 135), a sample of students (N = 145), and a sample of political party members (N = 47). According to value pluralism theory, advocates of extreme ideologies exhibit low levels of cognitive complexity. Context theory, in contrast, states that extremists think in a more complex and s...

We introduce L2K,P, a monadic second-order language for reasoning about trees which characterizes the strongly Context-Free Languages in the sense that a set of finite trees is definable in L2K,P, if it is (modulo a projection) a Local Set-the set of derivation trees generated by a CFG. This provides a flexible approach to establishing language-theoretic complexity results for formalisms that a...

A cognitive architecture is presented, which combines insights from artificial intelligence with cognitive psychology, biology, and linguistics. Using a Super Mario clone, we equipped the simulated agents with (i) motivational behavioral systems, (ii) reasoning and planning capabilities, (iii) event-based schema learning and sensorimotor exploration, and (iv) speech comprehension and generation...

conclusions with growing cohort of young and middle-aged people, there is a probable risk of upsurge of ard. presently, there are dilemmas over the diagnosis of independent ard. thus, there is a need to develop evidence-based guidelines for diagnosis and management of ard through further systematic studies. results the prolonged and excessive use of alcohol may lead to structural and functional...

A recent hypothesis in empirical brain research on language is that the fundamental difference between animal and human communication systems is captured by the distinction between finitestate and more complex phrase-structure grammars, such as context-free and context-sensitive grammars. However, the relevance of this distinction for the study of language as a neurobiological system has been q...
