Differential latency and selective nondisclosure in verbal self-reports

Several previous studies have examined the correspondence between self-reports and the delayed identity match-to-sample performance they supposedly described. The present two experiments used similar procedures to explore different characteristics of the self-reports. In both studies, match-to-sample responses were successful (earned points) if they were both correct and faster than a time limit. Following each response, a computer-presented query asked whether the response had been successful, and subjects replied by pressing a "Yes" or "No" button. Experiment 1 analyzed self-report latencies from a previously-published study (Critchfield, 1993a). Latencies generally were longer for self-reports of failure than for self-reports of success. In Experiment 1, a "Yes" or "No" self-report was required to advance the session. In Experiment 2, self-reports were optional. In addition to "Yes" and "No" buttons, subjects could press a third button (a "nondisclosure" option) to remove the self-report query without providing a "Yes" or "No" answer. Across a range of conditions, nondisclosures always occurred more frequently after match-to-sample failures than after successes (i.e., under conditions in which a self-report of failure would be appropriate). The effects observed in the two experiments are consistent with a history of differential punishment for uncomplimentary self-reports, which casual observation and some descriptive studies suggest is a common experience in United States culture. The research necessary to explore this notion should produce data that are of interest to psychologists both within and outside of Behavior Analysis.
