Abstract

This research examined the conceptual structure of semantic memory in schizophrenics. The study involved nineteen schizophrenics and twenty-one normal controls and employed an associative concept dictionary. The relationship between number of words and distance between concepts was examined using the association experiment. The association concept dictionary to examine the conceptual structure in man’ s memory using large-scale association experiments is structurizing of the associative memoryThe result of the experiment suggested that the schizophrenics correctly inferred the distance between concepts and the association number of words, and that the conceptual structure was different.Using an association experiment, it is possible to research a schizophrenic patient’s long-term meaning memory and its relation to the symptoms in further detail, based on a substantial amount of information on the conceptual structure. In addition, the distance between concepts was significantly high in the schizophrenic patients compared with that of the controls.
