We measured subjective-tone identification thresholds evoked by acoustically filtered complex tones and compared them to Mandarin-Chinese tone-phoneme identification thresholds previously measured under the same filtering conditions. Tone phonemes were identified at intensities below subjective-tone identification thresholds, suggesting subjective tone is not necessary for tone-phoneme identification. Lower subjective-tone thresholds evoked by resolved harmonics rather than unresolved harmonics were consistent with pattern recognition theories of pitch perception.The authors thank Donald Gans and Richard Klich for all their help.  相似文献

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 7-year-old adopted and nonadopted sibling pairs in the Colorado Adoption Project in order to assess differential genetic influence on specific mental abilities. Model fitting results and Schmid-Leiman (Schmid & Leiman, 1957) transformations reveal significant heritable variation for verbal, spatial, and memory factors independent of general cognitive ability for the eight ability tests examined. In contrast, environmental influences are primarily measure-specific. The results suggest genetic effects in middle childhood that differentially influence mental ability scores.  相似文献

Traditionally, communication skills training has focused principally on overt behaviours that are clearly identifiable. In recent years there has been an increasing awareness that cognitive processes can have considerable influence on behaviour. An attempt was made to establish whether changes in cognitions occurred as a result of a behaviourally-based communication skills training programme in which there had been no explicit attempt to bring about such cognitive changes. More specifically, the study examined whether such a programme resulted in changes in aspects of the personal construct space of students on a Diploma in Careers Guidance course. The results offered some support for the hypothesis that the programme produced changes in the students' personal construct space.  相似文献

The desire to merge identities with an intimate partner was found to be negatively related to psychoticism but related to other social desires, such as the desire for physical closeness and identifying with the achievements of others.  相似文献

An expanded view of health is advocated for assessment and treatment of individual clients in helping them achieve and maintain their maximum potential for high-level wellness. In addition, moderating variables, such as culture, age, and gender differences, have an impact on every dimension of health and wellness. In this article a multidimensional systems model for wellness is described, and gender differences along those dimensions are reviewed. Application of the model and implications for counseling are discussed. Finally, two illustrative case examples, one man and one woman, are described.  相似文献

The present research examined whether line-ups based on target (‘suspect’) face similarity are biased or suggestive. Four experiments are described in which subjects constructed photographic line-ups by selecting foils similar in appearance to a target. Later, another group of subjects who had not seen the faces before (mock witnesses) were asked to pick out the targets from the line-ups. All four experiments showed that mock witnesses selected the target significantly more often than expected by chance, thereby demonstrating suggestiveness. Three alternative line-up construction methods were also evaluated. In these methods, foil selection was based not only on target similarity but also on similarity with one or more of the other line-up faces. Results showed that alternative line-up targets were not selected significantly more often than chance, suggesting that bias was reduced. An overall analysis showed that the alternative line-ups were significantly less suggestive than target-based line-ups. The results indicate that foil selection procedures that incorporate foil-to-foil similarity produce fairer line-ups than those exclusively based on target similarity.  相似文献
