The control of language use has in its simplest form perhaps been most intensively studied using the color-word Stroop task. The authors review chronometric and neuroimaging evidence on Stroop task performance to evaluate two prominent, implemented models of control in naming and reading: GRAIN and WEAVER++. Computer simulations are reported, which reveal that WEAVER++ offers a more satisfactor...

Research on psychopathy in women has generated equivocal laboratory findings. This study examined the performance of psychopathic women in 2 laboratory tasks designed to assess abnormal selective attention associated with response modulation deficits: a computerized picture-word (PW) task, and a picture-word Stroop (PW Stroop) task. Consistent with data from psychopathic men, women receiving hi...

OBJECTIVE The aim of this study was to investigate whether the previously reported differences in cognitive performance as assessed using a Stroop paradigm between individuals with and without tinnitus is present in normal-hearing individuals. DESIGN Participants completed audiometric evaluation, a visual Stroop test, as well as the Swedish version of the hospital anxiety and depression scale...

Two experiments examined the relations among working memory capacity (WMC), congruency-sequence effects, proportion-congruency effects, and the color-word Stroop effect to test whether congruency-sequence effects might inform theoretical claims regarding WMC's prediction of Stroop interference. In Experiment 1, subjects completed either a high-congruency or low-congruency Stroop task that restr...

BACKGROUND/AIMS The Stroop test is commonly applied in elderly subjects for the evaluation of cognitive impairment related to Alzheimer's disease (AD) and related disorders. This study aimed to investigate the functional neural correlates of the Stroop performance in AD. METHODS In 136 probable AD patients and 54 cognitively normal elderly, a [(18)F]-fluorodeoxyglucose positron emission tomog...

Four experiments investigated Stroop interference using geometrically transformed words. Over experiments, reading was made increasingly difficult by manipulating orientation uncertainty and the number of noncolor words. As a consequence, time to read color words aloud increased dramatically. Yet, even when reading a color word was considerably slower than naming the color of ink in which the w...

We report distributional analyses of response times (RT) in two variants of the color-word Stroop task using manual keypress responses. In the classic Stroop task, in which the color and word dimensions are integrated into a single stimulus, the Stroop congruence effect increased across the quantiles. In contrast, in the primed Stroop task, in which the distractor word is presented ahead of col...

We studied the influence of attention on the timecourse of Stroop-like conflict. Thirty-two volunteers performed a Stroop matching task in which they had to compare either the color (n = 16) or meaning (n = 16) of two stimuli. The first stimulus was always a color-name printed in yellow, red, or blue (i.e., Stroop stimulus), and the second stimulus was either a color-bar (Experiment 1) or color...

Extensive studies have been conducted to examine various attentional control effects that stem from stimulus-stimulus (S-S) and stimulus-response (S-R) incompatibility. Among these behavioral paradigms, the best-known are the Stroop effect, the Simon effect, and Posner's cue validity effect. In this study, we designed two behavioral tasks incorporating these effects (Simon-color-Stroop and Simo...

Inconsistent results in the field of bilingualism and cognition may be largely influenced by variation in the nature of bilingual language proficiency. Here we explore the relationship between inhibitory control and bilingual proficiency in 43 8-year-old English-Chinese children in Singapore where bilingualism is prolific. Proficiency estimates are based on Oral and Written exam scores and care...
