Within Subjects

We examined changes in learning and in the content of verbal reports as a function of the regularity of introspective probes. Using a within-subjects design, concurrent undirected introspection was required on 0%, 50%, or 100% of the trials of a concept-identification task. The data for 18 subjects showed no differences in learning across 3 conditions. Verbal reports were classified according to the types of mental processes they indicated, e.g., hypothesis-testing. Analysis of the proportions of observed types suggested that the attention of subjects under the 100% condition wandered more to thoughts unrelated to the task than under the 50% condition; otherwise, the content of the verbal reports was uniform across these conditions. Undirected concurrent introspection seems to be a noninterfering, useful method for studying the nature of complex thinking.

Linguistic Categorization

An attempt was made to determine the degree of relationship between 48 Ss' verbal descriptions of three-dimensional, binary-valued stimuli, and the linguistic structure present in the hypothesis-testing sequences when these Ss were presented with the same stimuli in a simple concept-identification task. It was observed that Ss manifested a type of “gambler's fallacy” when testing hypotheses in such situations, and that this imposes a structure on Ss concept-identification performance which, to a large extent, obscures the linguistic patterns which were observed to occur.

After Error

Predetermined sequences of stimuli and a direct measuring technique were used to estimate the specific hypotheses Ss used to solve concept-identification problems. Results indicate that Ss did not choose hypotheses at random and that the focus sample of most Ss contained those hypotheses which were consistent with reinforcement on previous trials. A comparison was also made between predictions of the Trabasso and Bower (1968) and Chumbley (1969) models concerning Ss' sampling behavior after error trials. Ss eliminated irrelevant hypotheses on both error and correct choice trials at about the same rate, supporting the predictions of the Chumbley (1969) model.
