In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice.  相似文献

The role of phonological coding for character identification was examined with the benefit of processing parafoveal characters in eye fixations while reading Chinese sentences. In Experiment 1, the orthogonal manipulation of phonological and orthographic similarity can separate two types of phonological benefits for homophonic previews, according to whether these previews share the same phonetic radical with the targets or not. The significant phonological benefits indicate that phonological coding is activated early when the character is in the parafovea. Experiment 2 manipulated the character's consistency value and found that the phonological preview benefits are reliable only when the targets are high consistency characters. The results of two experiments suggest that phonological computation is rapid and early at both character and radical levels for Chinese character identification.  相似文献

Fourteen native speakers of German heard normal sentences, sentences which were either lacking dynamic pitch variation (flattened speech), or comprised of intonation contour exclusively (degraded speech). Participants were to listen carefully to the sentences and to perform a rehearsal task. Passive listening to flattened speech compared to normal speech produced strong brain responses in right cortical areas, particularly in the posterior superior temporal gyrus (pSTG). Passive listening to degraded speech compared to either normal or flattened speech particularly involved fronto-opercular and subcortical (Putamen, Caudate Nucleus) regions bilaterally. Additionally the Rolandic operculum (premotor cortex) in the right hemisphere subserved processing of neat sentence intonation. As a function of explicit rehearsing sentence intonation we found several activation foci in the left inferior frontal gyrus (Broca's area), the left inferior precentral sulcus, and the left Rolandic fissure. The data allow several suggestions: First, both flattened and degraded speech evoked differential brain responses in the pSTG, particularly in the planum temporale (PT) bilaterally indicating that this region mediates integration of slowly and rapidly changing acoustic cues during comprehension of spoken language. Second, the bilateral circuit active whilst participants receive degraded speech reflects general effort allocation. Third, the differential finding for passive perception and explicit rehearsal of intonation contour suggests a right fronto-lateral network for processing and a left fronto-lateral network for producing prosodic information. Finally, it appears that brain areas which subserve speech (frontal operculum) and premotor functions (Rolandic operculum) coincidently support the processing of intonation contour in spoken sentence comprehension.  相似文献

Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name agreement was controlled, suggesting inhibitory effects from lexical competitors. For all the languages, word frequency and goodness of depiction had large effects, but objective picture complexity did not. Effects of word structure variables (length, syllable structure, compounding, and initial frication) varied markedly over languages. Strong cross-language correlations were found in naming latencies, frequency, and length. Other-language frequency effects were observed (e.g., Chinese frequencies predicting Spanish reaction times) even after within-language effects were controlled (e.g., Spanish frequencies predicting Spanish reaction times). These surprising cross-language correlations challenge widely held assumptions about the lexical locus of length and frequency effects, suggesting instead that they may (at least in part) reflect familiarity and accessibility at a conceptual level that is shared over languages.  相似文献

Recent events have underlined in the most tragic and dramatic way the need for depth psychology to turn its attention to the psychology of terror. The present paper attempts to distinguish between the psychological modes of horror and terror and explores the different theoretical approaches of Burke, Freud, Kristeva and Jung to this problem in order to cast light on the individual and collective functions that horror and terror play. While all these authors stress that terror and horror play a role in structuring the sense of identity and in strengthening community bonds, Freud and Kristeva believe that the experience of horror works to increase the exclusion of otherness through mechanisms of repression or foreclosure while Burke and Jung see in the encounter with the Negative Sublime or with the Shadow the possibility of widening the boundaries of ego consciousness and of integration of 'otherness'. The paper then uses the analysis of two horror movies and of a particular socio-cultural context to illustrate these different functions of horror and terror and to delineate possible solutions to the problems facing society.  相似文献

The Internet appears to offer psychologists doing research unrestricted access to infinite amounts and types of data. However, the ethical issues surrounding the use of data and data collection methods are challenging research review boards at many institutions. This article illuminates some of the obstacles facing researchers who wish to take advantage of the Internet's flexibility. The applications of the APA ethical codes for conducting research on human participants on the Internet are reviewed. The principle of beneficence, as well as privacy and confidentiality, informed consent, deception, and avoiding harm are all illustrated through the use of a hypothetical online study.  相似文献

Questioning the Link Between PTSD and Cognitive Dysfunction   总被引:2,自引:0,他引:2  
Posttraumatic stress disorder (PTSD) has been linked with impairment in cognitive functioning, but anomalies appear to arise on several levels, masking the true nature of the relationship. On one level, there is a blurring of the emotional and physical causes of cognitive dysfunction, especially with memory problems that are similar to those due to neurological disorders. At other levels, problems are evident due to issues such as overgeneralizing from specific populations to the general population, and the use of narrow-focused neuropsychological assessment instruments that neither dissociate among precise memory components nor relate to everyday situations. In this review we highlight methodological problems and concerns, and make suggestions to establish valid links between PTSD and cognitive dysfunction.  相似文献

Many written English words contain silent letters. Omitting them produces nonwords pronounced identically to the original words, for example, SALM for PSALM and COLUM for COLUMN. We report two naming and two lexical decision experiments in which targets of 4–11 letters followed primes exposed for 100 ms in mask-prime-mask-target sequences. Priming in SALM-psalm and COLUM-column pairs exceeded priming in orthographic control pairs such as ASTA-pasta and COUSI-cousin, pairs in which pronounced letters are omitted to form the primes. SALM and COLUM, however, were less effective primes than PSALM and COLUMN. Results were discussed in terms of the phonological coherence hypothesis, the role of orthographic codes in filtering phonologically activated representations, and graphemes as reading units.  相似文献
