“…While hyperattentional dysfunctions (i.e., the breakdown of filtering functions, the overprocessing of irrelevant stimuli and the resulting exhaustion of processing capacity; e.g., Grillon, Courchesne, Ameli, Geyer, & Braff, 1990) have been considered a main force in the evolution of schizophrenia, traditional neuropsychological tests such as the continuous performance test (CPT) are not designed to reveal the specific nature of the attentional impairments in these patients (e.g., Cullum, Harris, Waldo, Smernoff, Madison, Nagamoto, Griffith, Adler, & Freedman, 1993;Elliott & Sahakian, 1995;Lieb, Merklin, Rieth, Schüttler, & Rieth, 1994;McKenna, Tamlyn, Lund, Mortimer, Hammond, & Baddeley, 1990;Pigache, 1996;Weiss, 1996). However, schizophrenic patients were shown to outperform normals with 1 Nosology-driven reasoning has also resulted in rather pessimistic judgements about the potential of animal research in schizophrenia.…”

“…This could be especially important when speed of information processing is partly responsible for lower intelligence in schizophrenia. It has been known for some time that speed of information processing is impaired in schizophrenia, and also when patients are not medicated (28–32). Like intelligence, speed of information processing is already apparent at the onset of psychotic illness (33).…”

These findings are important in considering the value of intelligence levels in schizophrenia. IQ scores should be judged in combination with cognitive functioning and school career to assess a patients capabilities in society. Cognitive functions and other variables might have a considerable influence on IQ scores. This rises the question of whether the low IQ scores are a primary or secondary deficit. Schizophrenia patients may have normal IQs, but could be less capable of making an IQ-test.

“…The RSAT is suitable for use in patients with schizophrenia because it is easy to access and administer. Moreover, the RSAT identifies the severity level of cognitive impairment concerning daily life functioning [ 30 ]. Some studies have suggested that the RSAT might differentiate dysfunctions in the left and right hemispheres [ 31 , 32 ].…”

Background: The Ruff 2 and 7 Selective Attention Test (RSAT) is designed to measure selective attention. It tests automatic detection speed (ADS), automatic detection errors (ADE), automatic detection accuracy (ADA), controlled search speed (CSS), controlled search errors (CSE), and controlled search accuracy (CSA). The purpose of this study was to examine the test–retest reliability, practice effect, and minimum detectable change (MDC) of the RSAT in patients with schizophrenia. Methods: A total of 101 patients with schizophrenia completed the RSAT twice at a 4-week interval. The intra-class correlation coefficient (ICC), paired t test, and effect size were used to examine the test–retest reliability and practice effect. The standard error of measurement (SEM) and MDC were calculated. Results: The difference scores between the two assessments were significant in all the indexes. The absolute effect sizes were 0.14 to 0.30. The ICCs of the RSAT ranged from 0.69 to 0.91. The MDC% in the indexes of ADS, ADA, and CSA of the RSAT were <30%. Conclusions: The RSAT is reliable for assessing selective attention in patients with schizophrenia. The RSAT has good to excellent test–retest reliability, a trivial to small practice effect, and indexes of ADS, ADA, and CSA, representing acceptable random measurement error.
