Two studies were conducted to examine gymnasts' memory capabilities in relation to skill level (high and low) and age level (6–8 years and 14–16 years). The first experiment consisted of two trials performed 7 days apart. In the first trial, gymnasts were briefly exposed to a twelve‐element floor routine, and were then required to perform the routine in the same serial order. One week later they were again briefly presented the same sequence, but with the fifth and seventh elements missing. The task was to perform the sequence in order, including the missing elements. The second study involved three trials that were conducted on the same day. A ten‐element sequence was briefly presented on the first trial followed by an immediate test of that sequence. One hour later, participants were asked to perform the sequence again (delayed test). An hour following that, the sequence was again presented with two elements missing. The sequence had to be performed with the missing elements. The results indicate that serial position accuracy of a gymnastic floor routine improves with both age and experience, and that the older experienced gymnasts outperformed all the other gymnasts on all phases of the experiments. These results are interpreted within the Ericsson and Kintsch (1995) theory of Long‐term Working Memory. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Standard approaches to cognition emphasise structures (representations and rules) much more than processes, in part because this appears to be necessary to capture the normative features of cognition. However the resultant models are inflexible and face the problem of computational intractability. I argue that the ability of real world cognition to cope with complexity results from deep and subtle coupling between cognitive and non-cognitive processes. In order to capture this, theories of cognition must shift from a structural rule-defined conception of cognition to a thoroughgoing embedded process approach. 相似文献

Increasing evidence supports the efficacy of conjoint therapies that focus on intimate partner violence for couples who engage in mild to moderate physical aggression but want to preserve the relationship and end the aggression. However, there has been no examination of how this population responds to couple therapy that does not have a specific focus on aggression. This lacuna in the research literature is of concern because couples with a history of low-level aggression often seek couple therapy, but couple therapy without a focus on violence is thought to potentially exacerbate aggression. In the current study, the authors examined the efficacy of non-aggression-focused behavioral couple therapy for couples with and without a history of mild physical aggression. One hundred thirty-four couples, 45% of whom had experienced low-level aggression in the year prior to therapy, completed up to 26 sessions of couple therapy and 2 years of follow-up assessments. Results demonstrated no significant differences in relationship and individual outcomes by history of aggression. In addition, couples maintained very low levels of physical aggression during and after treatment and showed reductions in psychological aggression when relationship and individual functioning improved. 相似文献

Several studies have demonstrated that acquired expertise influences aesthetic judgments. In this paradigm we used functional magnetic resonance imaging (fMRI) to study aesthetic judgments of visually presented architectural stimuli and control-stimuli (faces) for a group of architects and a group of non-architects. This design allowed us to test whether level of expertise modulates neural activity in brain areas associated with either perceptual processing, memory, or reward processing. We show that experts and non-experts recruit bilateral medial orbitofrontal cortex (OFC) and subcallosal cingulate gyrus differentially during aesthetic judgment, even in the absence of behavioural aesthetic rating differences between experts and non-experts. By contrast, activity in nucleus accumbens (NAcc) exhibits a differential response profile compared to OFC and subcallosal cingulate gyrus, suggesting a dissociable role between these regions in the reward processing of expertise. Finally, categorical responses (irrespective of aesthetic ratings) resulted in expertise effects in memory-related areas such as hippocampus and precuneus. These results highlight the fact that expertise not only modulates cognitive processing, but also modulates the response in reward related brain areas. 相似文献

The relationship of analogical distance to analogical function and preinventive structure: the case of engineering design 总被引:3,自引:0,他引:3
Analogy was studied in real-world engineering design, using the in vivo method. Analogizing was found to occur frequently, entailing a roughly equal amount of within- and between-domain analogies. In partial support for theories of unconscious plagiarism (Brown & Murphy, 1989; Marsh, Landau, & Hicks, 1996) and Ward's (1994) path-of-least-resistance model, it was found that the reference to exemplars (in the form of prototypes) significantly reduced the number of between-domain analogies between source and target, as compared with using sketches or no external representational systems. Analogy served three functions in relation to novel design concepts: identifying problems, solving problems, and explaining concepts. Problem identifying analogies were mainly within domain, explanatory analogies were mainly between domain, and problem-solving analogies were a mixture of within- and between-domain analogies. 相似文献

Genetic Influence Helps Explain Variation in Human Fertility: Evidence From Recent Behavioral and Molecular Genetic Studies 总被引:1,自引:0,他引:1

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated. 相似文献

Genetically sterile male Norway rats, Rattus norvegicus, were tested in the laboratory to determine both 1) behavioral characteristics, and 2) the ability of sterile males to compete aggressively and sexually with wild Norway rat males. Sterile males were larger in weight, more frequently dominant, won as many fighting encounters, were as aggressive as wild males, and mounted females more frequently. Behavioral activities were similar for both strains when compared under laboratory conditions with no apparent abnormal behavior exhibited by the sterile males. Use of sterile males in biological control programs is discussed. 相似文献
