The framework of dimensional interaction was used to test the hypothesis that the Stroop effect is partially rooted in mismatches in baseline discriminability, with stimulus differences along the word dimension typically exceeding stimulus differences along the color dimension. Subjects made speeded classifications, with either keypresses or vocalizations, of either words or colors. Stroop cong...
Three experiments investigated the effects of advance information about orientation on the processing of relevant and irrelevant objects, as indicated by Stroop effects from color words located in either object. Four results were obtained. First, participants showed the expected modulation of the Stroop effect: words in the relevant object produced much larger Stroop effects than words in the i...
Previous studies show Stroop effect is stronger in the right visual field. However, (1) whether the lateralization patterns of two aspects of Stroop effects, facilitation and inhibition, for native Chinese speakers are similar to each other, and (2) whether secondary interference tasks modulate Stroop effect as in the studies about the lateralized Whorf effect, are remaining open questions. We ...
BACKGROUND The stimulant methylphenidate (MPH) and the nonstimulant atomoxetine (ATX) are the most commonly-prescribed pharmacological treatments for attention deficit/hyperactivity disorder (ADHD). However, the drug-specific mechanism of action on brain function in ADHD patients is not well known. This study examined differences in prefrontal hemodynamic activity between MPH and ATX in childre...
It is widely accepted that the presentation of a printed word "automatically" triggers processing that ends with full semantic activation. This processing, among other characteristics, is held to occur without intention, and cannot be stopped. The results of the present experiment show that this account is problematic in the context of a variant of the Stroop paradigm. Subjects named the print ...
Executive function (EF) skills enhance learning across domains, and are particularly linked to the acquisition of a second language. Previous studies have shown that bilingual individuals show enhanced EF skills in cognitive tasks where they attended a targeted dimension of a stimulus while inhibiting other competing cues. Brain imaging revealed that bilingual young adults' performances in the ...
Prior research provides robust support for the existence of a number of associations between colors and flavors. In the present study, we examined whether congruent (vs. incongruent) combinations of product packaging colors and flavor labels would facilitate visual search for products labeled with specific flavors. The two experiments reported here document a Stroop-like effect between flavor w...
Two experiments examined the relations among working memory capacity (WMC), congruencysequence 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 lowcongruency Stroop task that restric...
Components of the Stroop task were examined to investigate the role that inhibitory processes play in cognitive changes in healthy older adults and in individuals with dementia of the Alzheimer's type (DAT). Inhibitory breakdowns should result in an increase in Stroop interference. The results indicate that older adults show a disproportionate increase in interference compared with younger adul...
Research on the acute effects of exercise on cognitive performance by older adults is limited by a focus on nonhealthy populations. Furthermore, the duration of cognitive improvements after exercise has not been examined. Thus, this study was designed to test the immediate and delayed effects of acute exercise on cognitive performance of healthy older adults. Cognitive performance was assessed ...
