Reviews 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.

128 female Ss were asked to make 4 judgments about a young woman after reading her "job application portfolio." Five characteristics of the young woman were manipulated orthogonally. Ss were asked to report how each of the 5 manipulated factors had influenced each of their judgments. "Observer Ss," who had access only to very impoverished descriptions of each of the 5 factors, were asked to predict how each of the factors would influence each of the judgments. Results show that S (...) reports about the effects of the factors on the judgments were in general highly inaccurate; observer predictions were extremely similar to S reports; for the single judgment for which Ss showed substantial accuracy, observer predictions were as accurate as S reports. Results indicate that whatever introspective access to cognitive processes may exist, it is not sufficient to produce generally accurate reports about such processes, nor even to produce reports that differ much from those of poorly informed outside observers.
