Procedural learning benefits from memory processes occurring outside practice resulting in offline learning. Offline gains have been demonstrated almost exclusively for the ordinal structure of sequential motor tasks. Many skills also demand that the correct serial order of events be appropriately timed. Evidence indicates that the temporal aspect of a procedural skill can be encoded independent of serial order knowledge and governed by at least two distinct neural circuits. The present experiment determined if (a) offline gains emerge for temporal learning, and (b) if such gains occur for timing supervised by distinct timing systems. Participants experienced 216 practice trials of a 7-key press sequence that involved integer- or non-integer timing rhythms. Twenty-four hours after training 30 test trials were administered. Results revealed robust offline enhancement for timing performance of the non-integer based temporal sequences. This improvement was localized to stabilization of the required relative but not absolute time profiles. The neural circuitry central to supporting the performance of non-integer timing sequences is also a principal constituent of what is described as the "cognitive" timing system. Timing governed by this system appears most susceptible to offline gains via consolidation. 相似文献

The Reflective Function Scale was developed by Fonagy and colleagues (1998) to empirically measure the capacity to mentalize thoughts, intentions, feelings, and beliefs about oneself and others. Reflective Function (RF) has been reliably measured by the Adult Attachment Interview (AAI; Main and Goldwyn 1998), but its length (45-90 minutes) and the labor required to administer, transcribe, and code for RF may be prohibitive for many research studies. The present study measured the reliability and validity of the Brief Reflective Function Interview (BRFI; Rudden, Milrod, and Target 2005) by administering it to 27 undergraduate participants previously assessed using the AAI in another research study (Morrison 2010). The BRFI was coded reliably by two independent raters (ICC = .79) and yielded a highly significant positive correlation (r = .71) between RF scores obtained by BRFI and by AAI. The average administration time of the BRFI (M = 24.15 minutes) was significantly shorter than that of the AAI (M = 44.65 minutes). These findings suggest that the BRFI may offer a reliable, valid, and streamlined alternative to the AAI as a measure for coding RF. 相似文献

Despite long-standing calls for the individualization of treatments for depression, modest progress has been made in this effort. The primary objective of this study was to test two competing approaches to personalizing cognitive-behavioral treatment of depression (viz., capitalization and compensation). Thirty-four adults meeting criteria for Major Depressive Disorder (59% female, 85% Caucasian) were randomized to 16-weeks of cognitive-behavioral treatment in which strategies used were selected based on either the capitalization approach (treatment matched to relative strengths) or the compensation approach (treatment matched to relative deficits). Outcome was assessed with a composite measure of both self-report (i.e., Beck Depression Inventory) and observer-rated (i.e., Hamilton Rating Scale for Depression) depressive symptoms. Hierarchical linear modeling revealed a significant treatment approach by time interaction indicating a faster rate of symptom change for the capitalization approach compared to the compensation approach (d = .69, p = .03). Personalizing treatment to patients' relative strengths led to better outcome than treatment personalized to patients' relative deficits. If replicated, these findings would suggest a significant change in thinking about how therapists might best adapt cognitive-behavioral interventions for depression for particular patients. 相似文献

A widely held assumption in metamemory is that better, more accurate metamemory monitoring leads to better, more efficacious restudy decisions, reflected in better memory performance--we refer to this causal chain as the restudy selectivity hypothesis. In 3 sets of experiments, we tested this hypothesis by factorially manipulating metamemory monitoring accuracy and self-regulation of study. To manipulate monitoring accuracy, we compared judgments of learning (JOLs) made contemporaneously with a delayed retrieval attempt to JOLs either made at a delay without attempting retrieval or made immediately after study; in previous studies, delayed retrieval-based JOLs have robustly predicted recall with greater relative accuracy than have the other JOL types. To manipulate self-regulation of study, in Experiments 1A-1C and 2A-2C, we compared conditions in which participants' restudy selections were honored with conditions in which they were completely or randomly dishonored; in Experiments 3A-3C, we randomly honored or dishonored half of the restudy selections and half of the nonselections. Results revealed that the benefit of delayed, retrieval-based JOLs for final memory performance was due largely to the selection of more items for restudy rather than to better discriminations between items that would benefit more versus less from restudy. In most cases, gains in recall due to greater self-regulation of study did not increase with better monitoring accuracy; when they did, the effect was extremely small. The surprising conclusion was that restudy decisions were not very much more efficacious under conditions that yield greater monitoring accuracy than under those that do not. 相似文献

The conflict monitoring model of cognitive control posits that response conflict triggers a top-down enhancement of a task’s
representation in working memory. In the present study, we conducted a novel test of the conflict monitoring model using a
voluntary task switching paradigm. We predicted that a task’s representation would be enhanced following events associated
with high response conflict (i.e., incongruent trials and incorrect responses), leading participants to voluntarily choose
to repeat that task more often after these events than after events associated with low response conflict (i.e., congruent
trials and correct responses). In two experiments, performance following incongruent trials was consistent with the conflict
monitoring model. However, performance following incorrect trials did not fit with the model’s predictions. These findings
provide novel support for the conflict monitoring model while revealing new effects of incorrect trials that the model cannot
explain. 相似文献

Current evolutionary and cognitive theories of religion posit that supernatural agent concepts emerge from cognitive systems such as theory of mind and social cognition. Some argue that these concepts evolved to maintain social order by minimizing antisocial behavior. If these theories are correct, then people should process information about supernatural agents' socially strategic knowledge more quickly than non-strategic knowledge. Furthermore, agents' knowledge of immoral and uncooperative social behaviors should be especially accessible to people. To examine these hypotheses, we measured response-times to questions about the knowledge attributed to four different agents--God, Santa Claus, a fictional surveillance government, and omniscient but non-interfering aliens--that vary in their omniscience, moral concern, ability to punish, and how supernatural they are. As anticipated, participants respond more quickly to questions about agents' socially strategic knowledge than non-strategic knowledge, but only when agents are able to punish. 相似文献

Can children’s handedness influence how they represent abstract concepts like kindness and intelligence? Here we show that from an early age, right‐handers associate rightward space more strongly with positive ideas and leftward space with negative ideas, but the opposite is true for left‐handers. In one experiment, children indicated where on a diagram a preferred toy and a dispreferred toy should go. Right‐handers tended to assign the preferred toy to a box on the right and the dispreferred toy to a box on the left. Left‐handers showed the opposite pattern. In a second experiment, children judged which of two cartoon animals looked smarter (or dumber) or nicer (or meaner). Right‐handers attributed more positive qualities to animals on the right, but left‐handers to animals on the left. These contrasting associations between space and valence cannot be explained by exposure to language or cultural conventions, which consistently link right with good. Rather, right‐ and left‐handers implicitly associated positive valence more strongly with the side of space on which they can act more fluently with their dominant hands. Results support the body‐specificity hypothesis ( Casasanto, 2009 ), showing that children with different kinds of bodies think differently in corresponding ways. 相似文献

Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys' emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away from emotion-focused strategies or delay in the onset of regular use of distraction. The results provide a foundation for future researchers to examine the development of SRS in low-income young children. 相似文献

Lucid dreams occur when a person is aware that he is dreaming while he is dreaming. In a representative sample of German adults (N = 919), 51% of the participants reported that they had experienced a lucid dream at least once. Lucid dream recall was significantly higher in women and negatively correlated with age. However, these effects might be explained by the frequency of dream recall, as there was a correlation of .57 between frequency of dream recall and frequency of lucid dreams. Other sociodemographic variables like education, marital status, or monthly income were not related to lucid dream frequency. Given the relatively high prevalence of lucid dreaming reported in the present study, research on lucid dreams might be pursued in the sleep laboratory to expand the knowledge about sleep, dreaming, and consciousness processes in general. 相似文献
