C. Oriet and P. Jolicoeur (2003) reported 2 experiments in which the perceptual contrast of stimuli was manipulated in a task-switching paradigm. They failed to observe an interaction in the reaction time data between task switching, perceptual contrast, and response-stimulus interval. Using the locus of slack logic, they concluded from these results that early perceptual processing of stimuli awaits the completion of a task-set reconfiguration stage, rather than proceeding in parallel with it. Here, an assumption necessary for this argument is questioned, and it is shown that an existing computational model of task switching, without successive stages for task-set reconfiguration and perceptual processing, produces a similar pattern of data. Thus, C. Oriet and P. Jolicoeur's data are compatible with models in which early perceptual processing and task-set reconfiguration take place in parallel. 相似文献

Atypical events are both memorable and unrepresentative of their class. We tested the hypotheses that (a) people tend to recall atypical instances of events, and (b) when they are unaware of this, they rely on these atypical instances in forecasting their affective reactions to future events. In three studies, participants who were asked to recall an instance of an event and participants who were asked to recall an atypical instance of an event recalled equally atypical instances. However, only the former participants made extreme forecasts about their reactions to future events. The results suggest that the impact bias (the tendency to overestimate the affective impact of future events) may be due in part to people's reliance on highly available but unrepresentative memories of the past. 相似文献

A series of experiments is reported in which two monkeys emitted complex response patterns, not specified by the experimental program, during the DRL component of a multiple schedule. Administration of sodium pentobarbital and dl-amphetamine, drugs which disrupted the DRL performance, were also observed to suppress these collateral responses. Sequences of these collateral responses appear to mediate, at least in part, the timing process required for reinforced performance on the DRL schedule. 相似文献

Generating different synonym candidates and evaluating these candidates with respect to their synonymy with the stimulus word are two components of solving an open synonym task, which requires giving synonyms for a given word (cf. Janssen, Hoskens, & De Boeck, 1993). Separate subtasks were designed to identify these components. It is shown in this study that the generation component ability is primarily related to verbal fluency abilities, whereas the evaluation component ability is primarily related to verbal comprehension abilities. Moreover, evidence is given that these two component abilities can account for the correlations of the open synonym task with other ability measures. 相似文献
