The Wisconsin Card Sorting Test (WCST) is the standard task paradigm to detect human frontal lobe dysfunction. In this test, subjects sort card stimuli with respect to one of three possible dimensions (color, form and number). These dimensions are changed intermittently, whereupon subjects are required to identify by trial and error a new correct dimension and flexibly shift cognitive set. We d...

We compute the minimal angle spread with respect to uniform distribution in probability simplex. The resulting optimization problem is analytically solved. formula provided shows that approaches zero as dimension tends infinity. also discuss an application cognitive science.

Based on Robinson’s Cognition Hypothesis, this study explored the effects of task complexity on the lexical complexity of Iranian EFL students’ argumentative writing.This study was designed to explore the manipulation of cognitive task complexity along +/-single task dimension (a resource dispersing dimension in Robinson’s triadic framework) on Iranian EFL learners’ production in term of lexica...

Miller (1990) suggests that communication between linguistics and psychology is hampered for essentially cognitive reasons: linguists favor simplifying explanations while psychologists favor causal explanations. This paper reformulates this suggestion as three testable hypotheses. First, scientists vary in cognitive style from rationalist/nomological to empiricist/mechanistic. Second, linguisti...

Features of an Internet traffic time series can be estimated using dynamical systems. Dynamical systems may exhibit chaos and strange attractors [1] [2]. Since Internet traffic shows non stationarity and long term dependence among data samples, a cognitive polyscale approach should be taken to analyze the hidden features in a nonlinear data time series. It is necessary to estimate a reasonable ...

In this study, it was aimed to reveal the predictive power of demographic characteristics, cognitive flexibility and social appearance anxiety individuals in emerging adulthood on preoccupation with thought eating loss control over eating, which are sub-dimensions food craving. The design research structured according relational screening model. study group consists 551 participants, 395 (71.7%...

Hypotheses were tested regarding the effects of subjective current, retrospected, and anticipated person-environment fit on affective and somatic strain and well-being. Two-hundred seven university students preparing for annual academic examinations at an Indian university completed self-administered questionnaires measuring parameters of the hypotheses. A distinction was made between cognitive...

BACKGROUND/AIM The vertical dimension of occlusion is a very important parameter for proper reconstruction of the relationship between the jaws. The literature describes many methods for its finding, from the simple, easily applicable clinically, to quite complicated, with the use of one or more devices for determination. The aim of this study was to examine the possibility of determining the v...

In some tasks, children show improved performance when allowed to make choices about task features. We conducted two experiments to examine the nature of this effect on 4-year-olds’ cognitive flexibility. Children completed one of two conditions of the dimensional change card sort (DCCS), wherein children are asked to sort items by one dimension (e.g., shape), and then to switch and sort by ano...
