Abstract
Matched word and design recall tasks were constructed and used to assess the performance
of chronic schizophrenics on neuroleptics alone and on both neuroleptic and anticholinergic
drugs. The two groups of patients performed at an equally low level on both tasks,
without evidence for a differential deficit. The tasks did, however, evoke a differential
deficit in clustering performance for designs as opposed to words. Although clustering,
which is based on recall, is not necessarily as well matched for words and designs
as recall itself, this result suggests a lateralized dysfunction in brain structures
related to use of mnemonic organization at retrieval.
