Cognitive substrates of thought disorder, II: specifying a candidate cognitive mechanism.
OBJECTIVE In part I of this series, the authors found that semantic knowledge and organization accounted for most of the variance in thought disorder in a group of chronic schizophrenic patients. In the present study, they examined a possible cognitive mechanism within the semantic system that might produce thought disorder. METHOD Twenty patients with chronic schizophrenia and 21 normal comp...
متن کاملCognitive deficits and thought disorder: a retest study.
Manic (n = 26), schizophrenic (n = 26), and normal (n = 25) subjects were examined with a digit span distraction task and with a reality monitoring task. All subjects were tested twice at a 4-day interval, and a clinical assessment of thought disorder was conducted both times on the patients. We found that reality monitoring, distraction task performance, and clinical thought disorder were all ...
متن کاملThought disorder in schizophrenia: cognitive and neuroscience approaches.
Research with schizophrenics is reviewed in the areas of the startle reflex, subject-initiated evoked potentials, and two-stimulus evoked potentials. A hypothesis of an early (pre-100 ms) information-processing deficit is posited and further refined by results presented from brain evoked potentials during a backward-masking experiment. The implications of these findings for the speech component...
متن کاملCognitive deficits and thought disorder: II. An 8-month followup study.
Schizophrenic (n = 21) and manic (n = 19) patients were followed up an average of 8 months after an index assessment during an acute admission. These patients were tested at both assessments with laboratory tasks measuring distractibility and reality monitoring and were examined with clinical ratings of positive and negative thought disorder. For manic patients, none of the measures predicted t...
متن کاملSelf-other control: a candidate mechanism for social cognitive function
Despite ever-growing interest in the “social brain” and the search for the neural underpinnings of social cognition, we are yet to fully understand the basic neurocognitive mechanisms underlying complex social behaviors. One such candidate mechanism is the control of neural representations of the self and of other people (Brass et al., 2009; Spengler et al., 2009a), and it is likely that “commo...
