| Abstract: | Measures of selective attention and speed which have been employed in the study of disturbances of cognitive functioning in schizophrenia were used in a study of 20 MZ and 20 DZ normal twin pairs. Results suggest the presence of a genetic contribution to scores on such tasks, particularly for the speed measures. |
