Attentional cues in chronic schizophrenia: Abnormal disengagement of attention.

Abstract: Posner's (1980) reaction time (RT) paradigm was used to examine the engagement and disengagement operations of visual selective attention in patients with schizophrenia. In the 1st experiment, 14 medicated, chronic schizophrenic subjects (diagnosed by criteria of the Diagnostic and Statistical Manual of Mental Disorders; American Psychiatric Association, 1987) and 15 age-matched normal control subjects made a speeded response to a target preceded by a valid, an invalid, or no cue. Control subjects showed the e… Show more

“…Unlike controls, patients did not respond faster to visual alerting cues signaling the impending appearance of the target arrow. This deficit in alertness is consistent with previous classic information processing studies of schizophrenia (Neale & Oltmanns, 1980;Shakow, 1962) as well as more recent visual cue studies (Nestor et al, 1992).…”

“…The idea here is that efficient monitoring would be associated with greater slowing, disadvantage, or cost in RT for incongruent trials compared to neutral trials. As expected and consistent with prior research using a visual cue paradigm (Nestor et al, 1992), patients here showed significantly less attentional cost than did controls. This might simply reflect particularly slow responses for the patient group when dealing with stimuli that do not provide any relevant information, such as neutral flankers.…”

“…That these current data may reflect an impairment in both automatic and controlled processes of attention is somewhat of a departure from behavioral studies that typically find that controlled but not automatic attentional processes are compromised by schizophrenia (Kwapil et al, 1991;Nestor et al, 1990Nestor et al, , 1991Nestor et al, , 1992Oltmanns, 1978). In fact, Callaway and Naghdi (1982) suggested that automatic processes may be normal or supernormal in schizophrenia.…”

“…Neuropsychological data continues to help elucidate this issue by providing behavioral measures that can be linked to regional brain function. Evidence for impaired learning and memory (e.g., Calev et al, 1983;Saykin et al, 1991;Goldberg et al, 1993), attention (e.g., Nuechterlein and Dawson, 1984;Harvey et al, 1990;Nestor et al, 1992), and executive functions (e.g., Goldberg et al, 1987;Morrison-Stewart et al, 1992) has supported a model of fronto-temporal dysfunction in schizophrenia. The presence of these deficits at first presentation (e.g., Bilder et al, 1992;Saykin et al, 1994), combined with the lack of correlation with measures of chronicity (e.g., Goldberg et al, 1993;Nopoulos et al, 1994) are consistent with the neurodevelopmental hypothesis that stresses the relative stability of cognitive functions after the onset of schizophrenia (e.g., Weinberger, 1987;Wyatt, 1996).…”
