Further evidence for a deficit in switching attention in schizophrenia
Smith, G. L., Large, M. M., Kavanagh, D. J., Karayanidis, F., Barrett, N. A., Michie, P. T., & O'Sullivan, B. T. (1998) Further evidence for a deficit in switching attention in schizophrenia. Journal of Abnormal Psychology, 107(3), pp. 390-398.
In this study, sustained, selective, divided, and switching attention, and reloading of working memory were investigated in schizophrenia by using a newly developed Visual Attention Battery (VAB). Twenty-four outpatients with schizophrenia and 24 control participants were studied using the VAB. Performance on VAB components was correlated with performance of standard tests. Patients with schizophrenia were significantly impaired on VAB tasks that required switching of attention and reloading of working memory but had normal performance on tasks involving sustained attention or attention to multiple stimulus features. Switching attention and reloading of working memory were highly correlated with Trails (B - A) score for patients. The decline in performance on the switching-attention task in patients with schizophrenia met criteria for a differential deficit in switching attention. Future research should examine the neurophysiological basis of the switching deficit and its sensitivity and specificity to schizophrenia.
