The spacing of a fixed amount of study time across multiple sessions usually increases subsequent test performance—a finding known as the spacing effect. In the spacing experiment reported here, subjects completed multiple learning trials, and each included a study phase and a test. Once a subject achieved a perfect test, the remaining learning trials within that session comprised what is known as overlearning. The number of these overlearning trials was reduced when learning trials were spaced across multiple sessions rather than massed in a single session. In addition, the degree to which spacing reduced overlearning predicted the size of the spacing effect, which is consistent with the possibility that spacing increases subsequent recall by reducing the occurrence of overlearning. By this account, overlearning is an inefficient use of study time, and the efficacy of spacing depends at least partly on the degree to which it reduces the occurrence of overlearning. 相似文献

Optimal arousal models contend that high arousal contributes to inhibited athletic performance, whereas there is reversal theory research which indicates that high positive arousal may enhance performance. To test these claims, 22 male and 6 female elite athletes were induced into high arousal telic (goal-directed) and high arousal paratelic (non goal-directed, process focussed) motivational states and tested on a standard hand strength task. Personalized guided imagery techniques and paced breathing were used to change psychological and physiological arousal. Significant increases in strength performance occurred when arousal was high and experienced as pleasant excitement in the paratelic condition (i.e., high positive arousal). Heart rate and other indicators of parasympathetic and sympathetic nervous system activity were not found to mediate between psychological arousal and performance. Where athletic performance requires maximal motor strength over a short period, performance benefits of high arousal may be maximized by restructuring motivational state. 相似文献

This article presents a concept underlying excellence called resonance , which was developed based on research interviews and consulting practice with high-level performers from all walks of life. Findings suggest that many high-caliber performers follow a typical process as they become experts in their chosen field. They have a dream , which represents how they want to feel in their daily pursuits. They also engage in extensive preparation, which includes activities that enable them to live their dream. All of the participants faced obstacles, but they developed strategies to revisit their dream before they actually engaged in more preparation. This cyclical process that guided their performance and life has been termed resonance , which occurs when there is a seamless fit between their internal self and their external environment. It is captured in the resonance performance model (RPM), a heuristic model devised to guide the practice of consultants. The article also includes a discussion of the RPM in relation to other performance-related concepts such as flow, presents some recent and future research with resonance, and considers practical application for consultants who may be interested in using the RPM. 相似文献

Suicide among adolescents is an emerging global public health problem as well as a socioeconomic problem. Stress-coping strategies have been shown to be associated with suicidal ideation. We examined coping behaviors related to suicidal ideation and gender differences in adolescents using the data from the 2010 Korea Youth Risk Behavior Survey (ages 12–19 years; N = 73,238). Logistic regression analysis was used to evaluate associations between suicidal ideation and specific coping behaviors while controlling for potentially confounding variables. In both male and female groups, the coping behavior “drinking alcoholic beverages” and “smoking cigarettes” were positively associated with suicidal ideation. “Watching TV,” “playing online/mobile games,” and “sleeping” were negatively associated with suicidal ideation in both groups. In males, “engaging in sports” was negatively related to suicidal ideation. In females, “venting by talking to others” and “eating” were negatively related to suicidal ideation. The results indicate that there are gender differences in the effects of coping behaviors on adolescent suicidal ideation, and that developing adaptive coping strategies may function to reduce suicidality. Future studies are needed to examine whether improving coping skills can reduce suicidal ideation in a gender-specific manner. 相似文献

Learning to perform a skilled behavior is affected by the context of the practice session and the frequency of augmented feedback. We studied the combined effect of these variables in the acquisition of a ballistic, bi-directional lever movement pattern involving four different target locations as measured by performance in practice, retention, and transfer tests. Augmented feedback was presented in either an every-trial or a faded schedule during random and blocked practice. Consistent with the contextual interference effect, the blocked practice group produced lower errors in acquisition, but the random practice group outperformed the blocked practice group in both retention and transfer. In contrast, faded feedback did not have a beneficial effect on learning and degraded learning when provided during blocked practice. While the results were consistent with previous findings of random and blocked practice, they were not consistent with previous findings of reduced feedback frequencies. 相似文献

Research has shown that children of depressed mothers are at risk for problems in a variety of developmental domains; however, little is known about the effects of maternal depression on children's emerging understanding of false beliefs. In this study, 3 false belief tasks were administered to 5-year-old children whose mothers had either met criteria for major depressive disorder within the first 20 months of the child's life (n = 91) or had never been depressed (n = 50). Significant difficulties in performance were found among the children of depressed mothers, especially those whose mothers had experienced early and recent recurrent depressive disorder. Regardless of diagnostic status, children whose mothers exhibited negativity during problem-solving tasks administered at an earlier developmental period also were less likely to demonstrate false belief understanding. These effects remained even after child verbal ability was controlled. 相似文献

We determined risk factors that discriminate between suicide attempt (SA) adolescents and suicidal ideation only (SI only) adolescents using data from the 2010 Korea Youth Risk Behavior Web‐based Survey (12–19 years; N = 73,238). In males, heavy alcohol use, drug use, and high perceived sadness/hopelessness showed significant effects on the presence of SA versus the presence of SI only. In females, along with these variables, low academic achievement, poor perceived health status, high perceived stress, and unhealthy coping strategy were also significantly related to the presence of SA versus SI only. Therefore, clinical interventions targeting adolescents' psychological distress are warranted to prevent suicide. 相似文献

In demonstrations of part-list cuing inhibition, subjects who are shown a subset of studied list words recall fewer noncue words than subjects not shown such part-list cues. We propose that part-list inhibition is governed in part by an incongruency principle: Inhibition occurs to the extent that part-list cues induce a retrieval framework different from that used to encode list items. In Experiment 1, word lists were studied followed by a test of free recall either without cues, or with cue words serially organized to be either congruent or incongruent with the order of studied items. In Experiments 2-4, cues consisted of every second study item in the original presentation order (congruent ones) or reordered to form famous names or familiar idioms that had been hidden in the study list (incongruent cues). More part-list inhibition was observed with incongruent cues than congruent cues in all 4 experiments. 相似文献

I argue that Plato distinguishes between personal immortality and immortality of the soul. I begin by criticizing the consensus view that Plato identifies the person and the soul. I then turn to the issue of immortality. By considering passages from Symposium and Timaeus, I make the case that Plato thinks that while the soul is immortal by nature, if a person is going to be immortal, they must become so. Finally, I argue that Plato has a psychological continuity approach to personal identity. Thus, for Plato, a person becomes immortal by avoiding reincarnation and securing for themselves psychological continuity forever. 相似文献
