Congruency effects were examined using a manual response version of the Stroop task in which the relationship between the colour word and its hue on incongruent trials was either kept constant or varied randomly across different pairings within the stimulus set.

Whereas neuroimaging studies of healthy subjects have demonstrated an association between the anterior cingulate cortex (ACC) and cognitive control functions, including response monitoring and error detection, lesion studies are sparse and have produced mixed results. Due to largely normal behavioral test results in two patients with medial…

Emerging areas and critical problems related to computer-based testing are identified. Topics covered include adaptive testing; calibration; item selection; multidimensional items; uses of information processing theory; relation to cognitive psychology; and tests of short-term and spatial memory, perceptual speed and accuracy, and movement…

This investigation is a preliminary attempt to test not only the production, but also the perception, of…
