We investigated the retrieval specificity of retrieval-induced forgetting (RIF) of motor sequences. In two experiments, participants learned sequential finger movements, each consisting of the movement of two fingers of either the left or the right hand. In the learning phase, these motor sequences were graphically presented and were to be learned as responses to simultaneously presented letter stimuli. Subsequently, participants selectively practiced half the items of one hand. A final recall test then assessed memory for all initially learned items. We contrasted different kinds of selective practice with each other. Whereas retrieval practice required retrieving motor sequences in response to letter stimuli from the learning phase, extra study was an extension of the learning phase, that is, participants performed motor sequences in response to the same animation graphic display as in the learning phase again accompanied by the letter stimulus. All practice conditions strengthened the practiced items, but only retrieval practice resulted in RIF. Thus, the strengthening of items through practice did not suffice to induce forgetting of related motor sequences. Retrieval was a necessary component for practice to shape memory for body movements by impairing the subsequent recall of motor sequences that were related to the practiced motor sequences. 相似文献

Rhetorical theory suggests that rhythmic and metrical features of language substantially contribute to persuading, moving, and pleasing an audience. A potential explanation of these effects is offered by “cognitive fluency theory,” which stipulates that recurring patterns (e.g., meter) enhance perceptual fluency and can lead to greater aesthetic appreciation. In this article, we explore these two assertions by investigating the effects of meter and rhyme in the reception of poetry by means of event-related brain potentials (ERPs). Participants listened to four versions of lyrical stanzas that varied in terms of meter and rhyme, and rated the stanzas for rhythmicity and aesthetic liking. The behavioral and ERP results were in accord with enhanced liking and rhythmicity ratings for metered and rhyming stanzas. The metered and rhyming stanzas elicited smaller N400/P600 ERP responses than their nonmetered, nonrhyming, or nonmetered and nonrhyming counterparts. In addition, the N400 and P600 effects for the lyrical stanzas correlated with aesthetic liking effects (metered–nonmetered), implying that modulation of the N400 and P600 has a direct bearing on the aesthetic appreciation of lyrical stanzas. We suggest that these effects are indicative of perceptual-fluency-enhanced aesthetic liking, as postulated by cognitive fluency theory. 相似文献

Despite abundant evidence that systemic administration of adrenergic drugs and hormones can produce retrograde memory enhancement, the literature contains no clear demonstration that postlearning systemic administration of adrenergic antagonists produces retrograde amnesia. Here we demonstrate retrograde amnesia for a stressful learning task (a spatial water maze) with systemic administration of the β-adrenergic antagonist propranolol (5 mg/kg). The amnesic effect of the drug depended on the degree of learning in the subjects: Propranolol caused a robust retrograde amnesia in “good learners,” but did not significantly affect memory in “poor learners.” The findings provide critical additional support for the hypothesis that postlearning adrenergic activation modulates memory consolidation processes after emotionally stressful events and help explain previous failures to detect memory impairment after systemic administration of adrenergic blocking drugs. 相似文献

If doing what is best sets the right ideal of rational agency, then rational agents should do what they believe to be best. As long as we leave open the question what makes an option best, all plausible theories of rationality willfit into this framework. Consequently, rational agents will always want to do the things they believes to be best. This claim is an instance of what David Lewis calls the desire-as-belief thesis, which he has tried to refute. I reject Lewis' argument by criticizing his treatment of belief-change in respect of propositions about degrees of goodness. 相似文献

The results reported herein support the hypotheses that (1) situation-specific, contextual features of a task can cause people to use explanation-based reasoning (Pennington and Hastie, 1993); (2) such reasoning can cause experienced personnel, both individually and in two-person teams, to reinterpret the meaning of the same information when it is presented in two different ordered sequences; and (3) the result will be primacy or recency (or no) effects depending on whether the most recent conflicting information can be explained away or not, respectively. These results extend the belief-adjustment model proposed by Hogarth and Einhorn (1992), which does not address information reinterpretations, and always predicts recency effects for an evaluation task with a short series of conflicting information. More generally, the results demonstrate the importance of situation-specific, contextual features in understanding judgment processes. © 1997 John Wiley & Sons, Ltd. 相似文献

It is natural to think of causes as difference‐makers. What exact difference causes make, however, is an open question. In this paper, I argue that the right way of understanding difference‐making is in terms of causal processes: causes make a difference to a causal process that leads to the effect. I will show that this way of understanding difference‐making nicely captures the distinction between causing an outcome and helping determine how the outcome happens and, thus, explains why causation is not transitive. Moreover, the theory handles tricky cases that are problematic for competing accounts of difference‐making. 相似文献

In this article, I distinguish two models of personal integrity. The first, wholeheartedness, regards harmonious unity of the self as psychologically healthy and volitional consistency as ethically ideal. I argue that it does so at the substantial cost of framing ambivalence and conflict as defects of character and action. To avoid these consequences, I propose an alternate ideal of humility that construes the self as multiple and precarious and celebrates experiences of loss and transformation through which learning, growth, innovation, and dynamic relationship become possible. This ideal not only sustains prospects for integrity but is more suitable than wholeheartedness for recognizing practices of contestation, such as those involving potentially destabilizing encounters with difference that is common within pluralistic societies, as vital for rich, well‐lived lives. 相似文献
