  • Title: Identification of tone duration, line length, and letter position: an experimental approach to timing and working memory deficits in schizophrenia.
    Author: Elvevåg B, Brown GD, McCormack T, Vousden JI, Goldberg TE.
    Journal: J Abnorm Psychol; 2004 Nov; 113(4):509-21. PubMed ID: 15535784.
    Abstract:
    Patients with schizophrenia display numerous cognitive deficits, including problems in working memory, time estimation, and absolute identification of stimuli. Research in these fields has traditionally been conducted independently. We examined these cognitive processes using tasks that are structurally similar and that yield rich error data. Relative to healthy control participants (n = 20), patients with schizophrenia (n = 20) were impaired on a duration identification task and a probed-recall memory task but not on a line-length identification task. These findings do not support the notion of a global impairment in absolute identification in schizophrenia. However, the authors suggest that some aspect of temporal information processing is indeed disturbed in schizophrenia.
