“…31, 45, 55-58 In several of these studies, SZ patients showed more facilitation than normal controls, but no difference in RT interference 31, 59 . Similar findings of equivalent Stroop RT interference in SZ patients have also been reported in priming experiments that used Stroop stimuli, 38, 46, 60, 61 and in neuroimaging studies 62, 63 . Other studies that have measured top-down behavioral control have also failed to find deficits in SZ patients 64 .…”

Objective To examine whether overlapping cognitive deficits exist in currently drug-abstinent chronic methamphetamine (MA) abusers and schizophrenia (SZ) patients. Background Both SZ and chronic MA abuse are associated with frontostriatal disruption as well as deficits in cognitive control such as selective attention. To identify overlapping cognitive profiles, we compared performance of the two groups on the Stroop attention task. Method Data were analyzed from 69 MA abusers who had been MA-abstinent for differing periods of time and from 23 SZ patients and 38 non-substance-abusing controls. Results The MA abusers in early abstinence displayed more Stroop interference than the SZ patients (p= 0.004), long-term abstinent MA abusers (p= 0.009), and controls (p = 0.002). In the MA abusers, the magnitude of Stroop interference correlated positively with longer drug use [p = 0.01] and negatively with longer drug abstinence [p= 0.04]. No correlations were found between psychotic symptoms and task performance. Conclusions On this task of attentional selection, only the MA abusers in early stages of abstinence showed performance deficits compared to controls. More research is needed to further elucidate overlapping patterns between MA abuse and SZ.

“…Other behavioral studies have provided evidence for increased interference independent of general slowing (for review see Henik and Salo, 2004). The inconsistent findings might be related to methodological differences (as intertrial interval) or subjects investigated (Hepp et al, 1996;Salo et al, 2002). For example, patients with the paranoid subtype might exhibit increased interference (Carter et al, 1993).…”

“…In turn, this should lead to facilitation being greater than interference. By contrast, the general finding on this issue is that the facilitation effect is much smaller than the interference effect (Glaser & Glaser, 1989;Ikeda, Okuzumi, & Kokubun, 2013;MacLeod, 1991;Schmidt & Besner, 2008;Sugg & McDonald, 1994).…”

What Stroop tasks can tell us about selective attention from childhood to adulthood

A rich body of research concerns causes of Stroop effects plus applications of Stroop. However, several questions remain. We included assessment of errors with children and adults (N = 316), who sat either a task wherein each block employed only trials of one type (unmixed task) or where every block comprised of a mix of the congruent, neutral, and incongruent trials. Children responded slower than adults and made more errors on each task. Contrary to some previous studies, interference (the difference between neutral and incongruent condition) showed no reaction time (RT) differences by group or task, although there were differences in errors. By contrast, facilitation (the difference between neutral and congruent condition) was greater in children than adults, and greater on the unmixed task than the mixed task. After considering a number of theoretical accounts, we settle on the inadvertent word‐reading hypothesis, whereby facilitation stems from children and the unmixed task promoting inadvertent reading particularly in the congruent condition. Stability of interference RT is explained by fixed semantic differences between neutral and incongruent conditions, for children versus adults and for unmixed versus mixed task. We conclude that utilizing two tasks together may reveal more about how attention is affected in other groups.

Time course of inhibition and facilitation in patients with schizophrenia

Abstract: These results suggest that schizophrenia patients are better able to inhibit irrelevant stimuli that are immediate, but the sustainment of inhibition across very short time intervals (500 ms) may fade compared to controls.
