Prior research suggests that duration bias—the tendency to overestimate the duration of affective states—is due to individuals' inordinate focus on event‐related information. We propose that the impact of focusing on event‐related (vs. unrelated) content is moderated by the ease with which the information is brought to mind. In the present experiment, participants thought about a possible future negative event and made affective forecasts after retrieving either few or many aspects in their life that would be affected (or unaffected) by the event. Participants estimated longer duration of affective consequences when they retrieved event‐related rather than event‐unrelated information. However, this effect was restricted to conditions where the respective information was brought to mind easily. Importantly, results also revealed that individual differences in faith in intuition moderated the effect of manipulated ease of retrieval. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

An attempt was made to separate operant and elicited pecks occurring in multiple schedules of food reinforcement by moving the component stimuli to a second key, upon which pecks had no effect. The operant key stimulus was constant, regardless of the reinforcement schedule in effect. Experiments included two- and three-component multiple schedules and a comparison of the single-key and the two-key procedures. In general, conditions that typically produce positive contrast in single-key procedures reduced responding to the constant-stimulus key (induction) and increased responding to the component-stimulus key (contrast) in the two-key procedure. The results were interpreted as supporting the contention that two response classes, operant and elicited, are present in standard multiple schedules. In addition, elicited responses were strongly implicated in contrast phenomena. 相似文献

The present study was designed to investigate modifications in the triphasic EMG pattern during a forearm-flexion task at maximum speed which required three levels of movement accuracy. 36 subjects participated in 4 training sessions, performing a total of 200 repetitions of each movement. The fastest movement time was associated with the least accurate movement task. Likewise, the slowest movement time was found for the movement requiring the greatest accuracy. Differences in the duration and amplitude of agonist 1 activity, the start of agonist 2 activity, and the start and amplitude of antagonist activity were observed for the three movements. The results indicate that agonist 1 provides a propulsive force to initiate limb movement. The antagonist EMG activity was thought responsible for braking and correcting limb movement. Modifications in agonist 2 activity suggest this burst is related to movement velocity. 相似文献
