The Stroop Effect is the decreased accuracy and increased response times observed when participants are asked to indicate the printed color of a word that is itself a conflicting or incongruous color-word (respond “blue” to RED printed in blue), compared to color-naming of congruous words or control stimuli (BLUE or XXXX respectively, both printed in blue). Congruous trials (matching word color...

The ability to resist distraction is an important requirement for air traffic controllers. The present study examined the relationship between performance on the Stroop color-word interference test (a suggested measure of distraction suscept-iblliity) and impairment under auditory distraction on a task requiring the subject to generate random sequences of letters. Fifty male college students se...

Regional cerebral blood flow, an index of local neuronal activity, was measured using positron emission tomography (PET) during the performance of the classic Stroop color/word task in eight healthy right-handed subjects. In the first condition of this paradigm, subjects name the color of the words presented on a video monitor. All the words are the color names congruent to the color presented ...

The Stroop task is a popular neuropsychological test that measures executive control. Strong Stroop interference is commonly interpreted in neuropsychology as a diagnostic marker of impairment in executive control, possibly reflecting executive dysfunction. However, popular models of the Stroop task indicate that several other aspects of color and word processing may also account for individual...

OBJECTIVES Manual response time (RT) and P300 event-related potential (ERP) measures were recorded in a Stroop color naming task to determine if previous results with vocal responses would be obtained using an arbitrary stimulus-response (S-R) mapping. METHODS Subjects (n = 32) were instructed to respond to the display color of a word but to ignore its meaning. Display color was congruent, ne...

The Stroop effect is one of the best known phenomena in all of cognitive science and indeed in psychology more broadly. It is also one of the most long standing, having been reported by John Ridley Stroop in the published version of his dissertation in 1935 [1]. In its basic form, the task is to name the color in which a word is printed, ignoring the word itself. When the word is a color word p...

A connectionist model, which simulates the operation of prefrontal circuits during Stroop task is proposed. The Stroop test has traditionally been used as a measure of cognitive inhibition. The task is to inhibit an over-learned, habitual response (i.e., reading color words) in favor of an unusual, novel requirement (i.e., naming incongruously printed colors of color words). The longer duration...

The role of color in object representation was examined by using a variation of the Stroop paradigm in which observers named the displayed colors of objects or words. In experiment 1, colors of color-diagnostic objects were manipulated to be either typical or atypical of the object (eg a yellow banana versus a purple banana). A Stroop-like effect was obtained, with faster color-naming times for...

background: schizophrenia is a psychiatric disorder that impairs several intellectual functions, including attention processes.   objectives: to investigate attention deficit in a group of patients with schizophrenia.   method: thirty patients with schizophrenia hospitalized in three psychiatric wards in shiraz and isfahan and 30 normal healthy subjects matched for age, gender and years of educ...
