The Stroop task is a commonly used psychological test to study interferences that occur in cognitive control when two processes are in competition, and where a non habitual response needed to reach a defined goal competes with the habitual response. Many computer simulations already exist for this task, in neural networks and production systems. This paper presents a new simulation approach. It...

objectives: the present study aimsed to examine the reliability of forceplate parameters under both single and dual task conditions and in different levels of postural difficulty. methods & materials: the healthy elderly+65, were assessed with aone-week interval, with a random combination of three levels of postural difficulty (i.e., standing on a rigid surface with eyes open, standing on a rig...

Drawing on Robinson’s cognition hypothesis, the study attempted to examine how task conditions influence EFL learners’ oral performance and whether learners’ individual differences in terms of tolerance of ambiguity and self-efficacy mediate the effects of such conditions. To this end, 62 Iranian intermediate EFL learners from private language institutes in Tehran performed four dyadic decision...

A theoretical framework to conceptualize measure of behaviour complexity (BC), system complexity (SC) and task complexity (TC) was developed. From this framework cognitive complexity (CC) is derived as CC = SC + TC BC. In an empirical study to investigate different measures of cognitive complexity 6 beginners and 6 experts solved 4 different tasks with an interactive database management system....

This study comparatively evaluates the effectiveness of three visualization methods (list, matrix, network) and the influence of data complexity, task type, and user characteristics on decision performance in the context of business ecosystem analysis. We pursue this objective using an exploratory study with 14 prototypical users (e.g. executives, analysts, investors, and policy makers). The re...
