“…In rapid serial visual presentation (RSVP) paradigms, where participants need to identify a target among a series of rapidly presented distractors, individuals with schizophrenia are less likely than matched controls to miss-report the distractors as targets ( Boucart et al, 2000 ). Giersch et al (2002) also observed reduced interference from non-pertinent information in SSD during certain orientation matching tasks in which pertinent and non-pertinent information was physically separated. From an executive function perspective, this would indicate enhanced rather than reduced ability to inhibit task-irrelevant information.…”

Schizophrenia Spectrum Disorders (SSD) are known to be characterised by abnormalities in attentional processes, but there are inconsistencies in the literature that remain unresolved. This article considers whether perceptual resource limitations play a role in moderating attentional abnormalities in SSD. According to perceptual load theory, perceptual resource limitations can lead to attenuated or superior performance on dual-task paradigms depending on whether participants are required to process, or attempt to ignore, secondary stimuli. If SSD is associated with perceptual resource limitations, and if it represents the extreme end of an otherwise normally distributed neuropsychological phenotype, schizotypal traits in the general population should lead to disproportionate performance costs on dual-task paradigms as a function of the perceptual task demands. To test this prediction, schizotypal traits were quantified via the Schizotypal Personality Questionnaire (SPQ) in 74 healthy volunteers, who also completed a dual-task signal detection paradigm that required participants to detect central and peripheral stimuli across conditions that varied in the overall number of stimuli presented. The results confirmed decreasing performance as the perceptual load of the task increased. More importantly, significant correlations between SPQ scores and task performance confirmed that increased schizotypal traits, particularly in the cognitive-perceptual domain, are associated with greater performance decrements under increasing perceptual load. These results confirm that attentional difficulties associated with SSD extend sub-clinically into the general population and suggest that cognitive-perceptual schizotypal traits may represent a risk factor for difficulties in the regulation of attention under increasing perceptual load.

“…This is consistent with Anscombe's hypothesis (Anscombe, 1987) and so, in part, with our SI results. More recent work (Giersch et al, 2002) has reinforced this view and suggested that physical separation of brief distractors and targets is crucial for eliminating interference effects in patients. Clearly then, we are uncertain about the mechanisms of attentional capture or its role in altered SI in patients.…”

“…Johnson-Selfridge & Zalewski, 2001;Miller, Chapman, Chapman, & Collins, 1995). However, patients can show faster learning or responding than healthy controls in some paradigms (Baruch, Hemsley, & Gray, 1988;Giersch, Danion, Boucart, Roeser, & Abenhaim, 2002;Gray, Hemsley, & Gray, 1992;Kathmann, von Recum, Haag, & Engel, 2000;Schooler, Neumann, Caplan, & Roberts, 1997;Vaitl et al, 2002;Williams et al, 1998). One of theseÐStroop interference (SI)Ðis the slowing that occurs when a distractor (e.g., a colour word) conflicts with a response (e.g., naming an ink colour: see MacLeod, 1991).…”

“…Selective attention. A computerized selective attention task appropriate for children was adapted from tasks that have been shown to be sensitive to schizophrenia in adults (Boucart & Humphreys, 1997;Giersch, Danion, Boucart, Roeser, & Abenhaim, 2002; see Appendix S1 for a full description of the task and an example of the task stimuli). Dependent measures were the total proportion of correct responses and mean response time on correct responses.…”

Background Attention-deficit/hyperactivity disorder (ADHD) and childhood-onset psychosis (COP) are chronic, heterogeneous disorders with symptoms that frequently co-occur, but the etiology of their comorbidity is unknown. Studies of each disorder indicate that both ADHD and COP are associated with a range of neuropsychological weaknesses, but few neuropsychological studies have directly compared groups with ADHD and COP. Methods Groups with ADHD only (32 F, 48M), COP only (5 F, 5 M), ADHD + COP (9 F, 21 M), and a control group with neither disorder (25 F, 44 M) completed a neuropsychological battery that included measures of verbal working memory, response inhibition, response speed and variability, and selective attention. Results All three clinical groups exhibited significantly lower performance versus the control group on all neuropsychological measures, whereas the only significant difference between the clinical groups was a significantly larger weakness in verbal working memory in the groups with COP. Conclusions The frequent co-occurrence between COP and ADHD may reflect shared neuropsychological weaknesses that are most pronounced on measures of working memory and response variability.
