In two experiments, subjects indicated whether two pictures of familiar objects were equivalent. The picture pairs were identical, showed the same object in various perspectives and states, or showed different objects with varying degrees of conceptual relatedness. In Experiment 1, the equivalence criterion for judging the picture pairs was varied between subjects (identity of pictures; conceptual equivalence of objects at subordinate, basic, or superordinate level). The reaction times of the four subject groups suggest that a pictorial stimulus is not always mentally represented in the same way, and that the instructions given determine which attributes of the stimulus are represented. In Experiment 2, the visual similarity of the picture pairs was varied. The results indicate, at least with a basic-level equivalence instruction, that not only perceptual, but also non-perceptual, functional attributes are represented—namely, those that, according to Rosch et al. (1976), are common to the members of a superordinate category. 相似文献

Conclusion In conclusion, the present research demonstrated the deleterious effects of negative life events. Number of negative events was a significant predictor of psychological disorder even when initial disorder was statistically controlled. The cross-sectional regression findings provided some support for the stress-buffering effects of positive life events, but these effects were nonsignificant when initial disorder was statistically controlled. The cross-sectional and prospective regression findings suggest that received social support, as measured by the ISSB, does not have a direct or stress-buffering effect on psychological disorder. These analyses, however, demonstrated the direct and stress-buffering effects of perceived social support, as measured by the ISEL, and the data suggest that the ISEL is a promising measure of this construct.The authors thank Sheldon Cohen who provided helpful comments on an earlier version of this article. 相似文献

Matched groups of Broca's and Wernicke's aphasics, brain-damaged patients without aphasia and chronic schizophrenics were tested in a nonverbal matching task where the subject had to indicate which of two pictures was more closely linked to a clue picture. Eight additional verbal and nonverbal reference tasks were administered. Both aphasic groups performed worse than brain-damaged controls when the identification of individual attributes or actions shared by clue and referent was required, but were unimpaired when the two had a set of referential-situational associations in common. Factor analyses resulted for both groups in two factors, one of which represents general Language Impairment. For the Broca's aphasics this factor was closely related to general organic deficit as measured by the Trail Making Test; for the Wernicke's aphasics it was associated with tasks which might be considered illustrative of analytical competence in isolating and comparing individual features of objects or concepts. 相似文献

Experiments in golf putting and darts demonstrated that skilled performance is streaky. The tendency for outcome sequences to form streaks was greatest when the task difficulty was such that about half the trials were successful. Mixtures of the two activities were also streaky, even when periodic interruption made the individual components resemble a random Bernoulli process. Formal models of sequence structure revealed that waves in hit rate are associated with the appearance of streaks. 相似文献

Trust is a critical component of research: trust in the work of co-workers and colleagues within the scientific community;
trust in the work of research scientists by the non-research community. A wide range of factors, including internally and
externally generated pressures and practical and personal limitations, affect the research process. The extent to which these
factors are understood and appreciated influence the development of trust in scientific research findings. 相似文献

Context effects on the judgment of basic emotions in the face 总被引:1,自引:0,他引:1

This article reports on three experiments on the controversial topic of context effects in the judgment of emotion from the face. In Experiment 1 (N=169) subjects were shown either a happy, sad, or angry anchor face as context followed by a target slide of a neutral face. In Experiment 2 (N=119) subjects were shown an anchor of a happy or angry face as context and a sad face as target. In Experiment 3 (N=180) subjects were shown an anchor of a happy, sad, or surprised face as context and an angry face as target. All experiments used facial expressions from Ekman and Friesen'sPictures of Facial Affect (1976). Dependent measures included intensity ratings of pleasure and arousal dimensions (Mehrabian & Russell, 1974); a judgment of the intensity of six specific emotions expressed (happy, sad, angry, afraid, disgusted, and interested); and categorical judgments of emotions. Significant context effects were observed for the neutral target and, with smaller effects, for the angry and sad targets on dimensional and intensity ratings. The magnitude of the context effect depended on both the target and anchor facial expressions. Greater categorical agreement of emotion was obtained for the target when another face was provided as a context than when the target face was shown alone. These results provide an independent replication and extension of recent research (Russell, 1991; Russell & Fehr, 1987) on the relativity of facial affect judgment.This research was supported by the Faculty Development Grant from Hofstra University to the first author. 相似文献
