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.

The meaning of spontaneous skin conductance activity, and its relevance to appraisal theory, are examined. Spontaneous skin conductance activity is hypothesised to reflect task engagement, and thus to be correlated with appraisals of problem-focused coping potential. In a within-subjects design, subjects solved anagrams in which task difficulty was manipulated by varying both the difficulty of the anagrams and the amount of time available to solve them. In the most difficult condition, appraisals of coping potential were expected, and observed, to be (...) especially low, and these appraisals were predicted to produce selective disengagement from the task, yielding reduced skin conductance activity. Within trials, skin conductance activity increased at the start of the trials in all conditions, but decreased by the end of the trials in the most difficult condition only. At the end of the trials, both spontaneous response rate and maximum response amplitude were positively correlated, within-subjects, with appraisals of coping potential, and, even after controlling for task difficulty, with solving the anagram. These findings support the hypothesised relation between appraised coping potential and spontaneous skin conductance activity, and the interpretation of this activity as reflecting task engagement.
