The influence of movement kinematics on the accuracy of predicting the time course of another individual's actions was studied. A human point-light shape was animated with human movement (natural condition) and with artificial movement that was more uniform regarding velocity profiles and trajectories (artificial condition). During brief occlusions, the participants predicted the actions in order to judge after occlusion whether the actions were continued coherently in time or shifted to an earlier or later frame. Error rates and reaction times were increased in the artificial compared to the natural condition. The findings suggest a perceptual advantage for movement with a human velocity profile, corresponding to the notion of a close interaction between observed and executed movement. The results are discussed in the framework of the simulation account and alternative interpretations are provided on the basis of correlations between the velocity profiles of natural and artificial movements with prediction performance. 相似文献

Measurement invariance is a prerequisite for confident cross-cultural comparisons of personality profiles. Multigroup confirmatory factor analysis was used to detect differential item functioning (DIF) in factor loadings and intercepts for the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in comparisons of college students in the United States (N = 261), Philippines (N = 268), and Mexico (N = 775). About 40%-50% of the items exhibited some form of DIF and item-level noninvariance often carried forward to the facet level at which scores are compared. After excluding DIF items, some facet scales were too short or unreliable for cross-cultural comparisons, and for some other facets, cultural mean differences were reduced or eliminated. The results indicate that considerable caution is warranted in cross-cultural comparisons of personality profiles. 相似文献

Despite its frequent use to assess effects of environmental and pharmacological variables on short-term memory, little is known about the development of delayed matching-to-sample (DMTS) performance. This study was designed to examine the dimensions and dynamics of DMTS performance development over a long period of exposure to provide a more secure foundation for assessing stability in future research. Six pigeons were exposed to a DMTS task with variable delays for 300 sessions (i.e., 18,000 total trials; 3,600 trials per retention interval). Percent-correct and log-d measures used to quantify the development of conditional stimulus control under the procedure generally and at each of five retention intervals (0, 2, 4, 8 and 16-s) individually revealed that high levels of accuracy developed relatively quickly under the shorter retention intervals, but increases in accuracy under the longer retention intervals sometimes were not observed until 100-150 sessions had passed, with some still increasing at Session 300. Analyses of errors suggested that retention intervals induced biases by shifting control from the sample stimulus to control by position, something that was predicted by observed response biases during initial training. These results suggest that although it may require a great deal of exposure to DMTS prior to obtaining asymptotic steady state, quantification of model parameters may help predict trends when extended exposure is not feasible. 相似文献

Categories are learned and used in a variety of ways, but the research focus has been on classification learning. Recent work
contrasting classification with inference learning of categories found important later differences in category performance.
However, theoretical accounts differ on whether this is due to an inherent difference between the tasks or to the implementation
decisions. The inherent-difference explanation argues that inference learners focus on the internal structure of the categories—what
each category is like—while classification learners focus on diagnostic information to predict category membership. In two
experiments, using real-world categories and controlling for earlier methodological differences, inference learners learned
more about what each category was like than did classification learners, as evidenced by higher performance on a novel classification
test. These results suggest that there is an inherent difference between learning new categories by classifying an item versus
inferring a feature. 相似文献

The effect of context on the identification of common environmental sounds (e.g., dogs barking or cars honking) was tested by embedding them in familiar auditory background scenes (street ambience, restaurants). Initial results with subjects trained on both the scenes and the sounds to be identified showed a significant advantage of about five percentage points better accuracy for sounds that were contextually incongruous with the background scene (e.g., a rooster crowing in a hospital). Further studies with naive (untrained) listeners showed that this incongruency advantage (IA) is level-dependent: there is no advantage for incongruent sounds lower than a Sound/Scene ratio (So/Sc) of -7.5 dB, but there is about five percentage points better accuracy for sounds with greater So/Sc. Testing a new group of trained listeners on a larger corpus of sounds and scenes showed that the effect is robust and not confined to a specific stimulus set. Modeling using spectral-temporal measures showed that neither analyses based on acoustic features, nor semantic assessments of sound-scene congruency can account for this difference, indicating the IA is a complex effect, possibly arising from the sensitivity of the auditory system to new and unexpected events, under particular listening conditions. 相似文献

Two classic studies published 50 years ago showed how other people provide information that shapes the activation and interpretation of emotions. The present paper traces development of the social psychology of emotions from this starting point. Subsequent research into group-based and social appraisal has advanced understanding of the impact of social information on emotions and suggested new ways of investigating associated phenomena. Although potential integrations of interpersonal and group-oriented approaches offer promise for the future, the continuing focus on emotions as cognitively mediated effects of social factors should broaden to encompass dynamic relational processes. 相似文献

While the motif of the double serves a prominent role in Freud’s writings from early on, this essay is an examination of the determinative power of the double in two key texts, texts in which specific, new sets doubles emerge for the first time in Freud’s career. Totem and Taboo features a double that manifests itself primarily in the form of ambivalence. Beyond the Pleasure Principle features a double that manifests itself primarily in the form of a very peculiar conflict that also entails complicity. 相似文献
