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 educat...

The brain's attentional system identifies and selects information that is task-relevant while ignoring information that is task-irrelevant. In two experiments using functional magnetic resonance imaging, we examined the effects of varying task-relevant information compared to task-irrelevant information. In the first experiment, we compared patterns of activation as attentional demands were inc...

There are methodological complexities with the supraliminal-lexical versions of the modified versions of the Stroop tests that could be responsible for inconsistencies across the literature (Field & Cox, 2008). We tested whether a combination of subliminal-pictorial and classic Stroop tests can differentiate between dieters' and nondieters' food attentional bias (FAB). Participants were dieters...

The picture-word interference (PWI) paradigm and the Stroop color-word interference task are often assumed to reflect the same underlying processes. On the basis of a PRP study, Dell'Acqua et al. (Psychonomic Bulletin & Review, 14: 717-722, 2007) argued that this assumption is incorrect. In this article, we first discuss the definitions of Stroop- and picture-word interference. Next, we argue t...

BACKGROUND The Stroop test requires the individual to respond to specific elements of a stimulus, whereas inhibiting more automated processes. OBJECTIVE To compare the cardiovascular reactivity induced by the computerized version of the Stroop word-color test TESTINPACS with the traditional version based on the reading of printed words. METHODS The sample of convenience consisted of 20 wome...

objective: the purpose of this study is to compare the executive functions children and adolescents who suffer from attention deficit hyperactivity disorder (adhd) with normal children. method: twenty children with adhd were compared to 19 healthy children terms of some executive functions using the computerized version of tower london, continuous performance test (cpt), and stroop color test. ...

The color-word Stroop is a popular measure in psychological assessments. Evidence suggests that Stroop performance relies heavily on reading, an ability that improves over childhood. One way to influence reading proficiency is by orthographic manipulations. To determine the degree of interference posed by orthographic manipulations with development, in addition to standard color-Words (purple) ...

The Stroop color–word task cannot be administered to children who are unable to read. However, our color–object Stroop task can. One hundred and sixty-eight children of 31⁄2–61⁄2 years (50% female; 24 children at each 6-month interval) were shown line drawings of familiar objects in a color that was congruent (e.g., an orange carrot), incongruent (e.g., a green carrot), or neutral (for objects ...

The color word Stroop effect in bilinguals is commonly half the magnitude when the written and naming languages are different (between) than when they are the same (within). This between-within language Stroop difference (BWLS) is likened to a response set effect, with greater response conflict for response relevant than irrelevant words. The nature of the BWLS was examined using a bilingual St...
