Abstract— In the word-length effect (WLE), lists of shorter words are better recalled than lists of longer words This effect a fundamental to decay-based theories of verbal short-term memory, such as the phonological loop theory (Baddeley, 1986) The WLE has been attributed to the time taken to articulate words, not their structure, a critical point in the debate between decay and interference theories However, this article, we show that the traditional WLE comprises two opposed effects an advantage for words spoken more quickly (short words in terms of duration) and an advantage for words with more elements (long words in terms of complexity) We also report two interactions a disadvantage for a midlist change in duration and an advantage for a midlist change in complexity These results contradict simple decay- based theories and establish the importance of interference in short- term memory We discuss whether decay is also required 相似文献

We report three experiments investigating source memory for words that were called "new" on a recognition test. In each experiment, participants could accurately specify the source of words that they failed to recognize. Results also demonstrated that source memory for unrecognized items varied with the bias to respond "old" in recognition decisions: Participants displayed unrecognized source memory when they were told that 25% of the recognition test words were old (promoting conservative responding) but not when they were told that 75% of the test words were old (promoting liberal responding). Our results were successfully predicted by a multivariate signal detection approach to recognition/source memory. 相似文献

Studies on whether fixation cues provided in the first episode of divergent thinking tasks influence creative outcomes after incubation, as they do for convergent problem-solving tasks, remain limited. This research examined the beneficial effects of incubation using the delayed- and immediate-incubation paradigms. Participants in Experiment 1 were either provided or not provided fixation cues during the first episode of a new type of divergent-thinking task, similar to creating titles in plot stories. The results indicated that fixation cues moderated people’s creative outcomes after incubation. Going through incubation did not improve the participants’ creativity in the second episode for strong fixation cues. By contrast, an incubation period led to the generation of more divergent items in the second episode compared to the first episode for less strong fixation cues, and this led to the performance matching the condition without fixation cues. The results from Experiment 2 suggested that immediate incubation downsized the influence of fixation cues. Therefore, if people want to promote their creativity through a period of incubation, the outcomes may still depend on the conditions of environments in which the creative works are executed. 相似文献

Making mistakes or failing at tasks is a common occurrence in human life. People can respond to and cope with failure in many ways. In this research, we examine potential advantages of relatively emotional (versus cognitive) responses to failure. In particular, we study how effort and time spent in subsequent tasks depend on whether people predominantly focus on their emotions or their cognitions as they respond to a failure. We demonstrate that, left to their own means, people's cognitions upon a failure are mainly justificatory in nature and thus do not automatically have the commonly believed reflective, self‐improving qualities. We further argue and demonstrate that a relative focus on cognitions following a failure can prevent improvement in subsequent episodes, but a focus on emotions can allow for learning and, therefore, increased effort.
