Word association: multiple measures and multiple meanings

Investigated the interrelationships between reaction time and three major verbal word association variables (response commonality, idiosyncratic responses, and degree of logical relatedness) in schizophrenics (N = 42) and nonschizophrenic psychiatric controls (N = 30). This study investigated the degree to which these four measures assess similar or different components of associative thought disorder in the same Ss, using both verbal associative measures and a nonverbal performance measure. Results indicated that reaction time was largely independent of all verbal measures in schizophrenics. These data were discussed in regard to the meaning and interpretation of word association test data as a function of choice of dependent variables for measuring associative thought disturbance.
