(1 other version)Telling more than we can know: Verbal reports on mental processes.Richard E. Nisbett &Timothy D. Wilson -1977 -Psychological Review 84 (3):231-59.detailsReviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

The halo effect: Evidence for unconscious alteration of judgments.Richard E. Nisbett &Timothy D. Wilson -1977 -Journal of Personality and Social Psychology 35 (4):250-256.detailsStaged 2 different videotaped interviews with the same individual—a college instructor who spoke English with a European accent. In one of the interviews the instructor was warm and friendly, in the other, cold and distant. 118 undergraduates were asked to evaluate the instructor. Ss who saw the warm instructor rated his appearance, mannerisms, and accent as appealing, whereas those who saw the cold instructor rated these attributes as irritating. Results indicate that global evaluations of a person can induce altered evaluations (...) of the person's attributes, even when there is sufficient information to allow for independent assessments of them. Furthermore, Ss were unaware of this influence of global evaluations on ratings of attributes. In fact, Ss who saw the cold instructor actually believed that the direction of influence was opposite to the true direction. They reported that their dislike of the instructor had no effect on their rating of his attributes but that their dislike of his attributes had lowered their global evaluations of him. (shrink)
Knowing when to ask: Introspection and the adaptive unconscious.Timothy D. Wilson -2003 -Journal of Consciousness Studies 10 (9-10):131-140.detailsThe introspective method has come under attack throughout the history of psychology, yet it is widely used today in virtually all areas of the field, often to good effect. At the same time indirect methods that do not rely on introspection are widely used, also to good effect. This conundrum is best understood in terms of models of nonconscious processing and the role of consciousness. People have access to many of their feelings and emotions, and develop rich narratives about themselves (...) and their social worlds. These conscious states, accessible to introspective reports, are often good predictors of people’s behaviour. There is also a pervasive adaptive unconscious that is inaccessible via introspection. When using introspective reports researchers should be clear about which kinds of mental states they are trying to measure. (shrink)
