The features of perceived objects are processed in distinct neural pathways, which call for mechanisms that integrate the distributed information into coherent representations (the binding problem). Recent studies of sequential effects have demonstrated feature binding not only in perception, but also across (visual) perception and action planning. We investigated whether comparable effects can be obtained in and across auditory perception and action. The results from two experiments revealed effects indicative of spontaneous integration of auditory features (pitch and loudness, pitch and location), as well as evidence for audio—manual stimulus—response integration. Even though integration takes place spontaneously, features related to task-relevant stimulus or response dimensions are more likely to be integrated. Moreover, integration seems to follow a temporal overlap principle, with features coded close in time being more likely to be bound together. Taken altogether, the findings are consistent with the idea of episodic event files integrating perception and action plans. 相似文献

We conducted a two-study examination of relationships between abusive supervision and subordinates’ workplace deviance. Consistent with predictions derived from power/dependence theory, the results of a cross-sectional study with employees from three organizations suggest that abusive supervision is more strongly associated with subordinates’ organization deviance and supervisor-directed deviance when subordinates’ intention to quit is higher. The results also support the prediction that when intention to quit is higher, abusive supervision is more strongly associated with supervisor-directed deviance than with organization-directed deviance. These results were replicated in a second study, a two-wave investigation of people employed in a variety of industries and occupations. 相似文献

ABSTRACT— Young children tend to claim that moving artifacts and nonliving natural kinds are alive, but neglect to ascribe life to plants. This research tested whether adults exhibit similar confusions when verifying life status in a speeded classification task. Experiment 1 showed that undergraduates encounter greater difficulty (reduced accuracy and increased response times) in determining life status for plants, relative to animals, and for natural and moving nonliving things, relative to artifacts and nonmoving things. Experiment 2 replicated these effects in university biology professors. The professors showed a significantly reduced effect size for living things, as compared with the students, but still showed greater difficulty for plants than animals, even as no differences from the students were apparent in their responses to nonliving things. These results suggest that mature biological knowledge relies on a developmental foundation that is not radically overwritten or erased with the profound conceptual changes that accompany mastery of the domain. 相似文献

This study used a sample of 121 employed, married (or cohabitating) mothers with a high socioeconomic status (SES) primarily from the Midwest United States to examine the relationship between division of household labor, perceived fairness, and distress. Due to inconsistent findings in prior literature, perceived fairness was examined as both a mediator and moderator between division of household labor and distress. Analyses indicated that perceived fairness played a mediating (but not moderating) role, suggesting that an individual’s perceptions of fairness are one mechanism by which division of household labor influences marital and personal distress in married individuals. Post hoc analyses also indicated that increased marital distress may explain the link between perceived unfairness and personal distress. Although results must be interpreted with caution due to the selectivity of the sample, the present study provides additional support for the importance of perceived fairness in the link between division of household labor and distress. 相似文献

Participants were pretrained and tested on mutually entailed trigonometric relations and combinatorially entailed relations as they pertained to positive and negative forms of sine, cosine, secant, and cosecant. Experiment 1 focused on training and testing transformations of these mathematical functions in terms of amplitude and frequency followed by tests of novel relations. Experiment 2 addressed training in accordance with frames of coordination (same as) and frames of opposition (reciprocal of) followed by more tests of novel relations. All assessments of derived and novel formula‐to‐graph relations, including reciprocal functions with diversified amplitude and frequency transformations, indicated that all 4 participants demonstrated substantial improvement in their ability to identify increasingly complex trigonometric formula‐to‐graph relations pertaining to same as and reciprocal of to establish mathematically complex repertoires. 相似文献

The effects of saccadic bilateral (horizontal) eye movements on memory for a visual event narrative were investigated. In the study phase, participants were exposed to a set of pictures accompanied by a verbal commentary describing the events depicted in the pictures. Next, the participants were asked either misleading or control questions about the depicted event and were then asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Finally, recognition memory was tested using the remember-know procedure. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. The findings are discussed in terms of source monitoring, dual-process theories of memory and the potential neural foundations of such effects. 相似文献

During the first year of life, infants begin to have difficulties perceiving non‐native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non‐segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a language with fixed stress) have great difficulties in perceiving stress contrasts ( Dupoux, Pallier, Sebastián & Mehler, 1997 ), whereas speakers of Spanish (a language with lexically contrastive stress) perceive these contrasts as accurately as segmental contrasts. We show that language‐specific differences in the perception of stress likewise arise during the first year of life. Specifically, 9‐month‐old Spanish infants successfully distinguish between stress‐initial and stress‐final pseudo‐words, while French infants of this age show no sign of discrimination. In a second experiment using multiple tokens of a single pseudo‐word, French infants of the same age successfully discriminate between the two stress patterns, showing that they are able to perceive the acoustic correlates of stress. Their failure to discriminate stress patterns in the first experiment thus reflects an inability to process stress at an abstract, phonological level. 相似文献

Operant devices have been used for many years in animal behavior research, yet such devices a regenerally highly specialized and quite expensive. Although commercial models are somewhat adaptable and resilient, they are also extremely expensive and are controlled by difficult to learn proprietary software. As an alternative to commercial devices, we have designed and produced a fully functional, programmable operant device, using a PICmicro microcontroller (Microchip Technology, Inc.). The electronic operant testing apparatus (ELOPTA) is designed to deliver food when a study animal, in this case a bird, successfully depresses the correct sequence of illuminated keys. The device logs each keypress and can detect and log whenever a test animal i spositioned at the device. Data can be easily transferred to a computer and imported into any statistical analysis software. At about 3% the cost of a commercial device, ELOPTA will advance behavioral sciences, including behavioral ecology, animal learning and cognition, and ethology. 相似文献

[Horney, 1945] and [Horney, 1950] interpersonal theory [Horney, K. (1945). Our inner conflicts. New York, NY: W. W. Norton & Co., Inc.; Horney, K. (1950). Neurosis and human growth. New York, NY: W. W. Norton & Co., Inc.] postulated that individuals could move toward, move against, and move away from others as manifestations of their character development. In the present studies, it was hypothesized that Horney's tripartite theory might be useful in the elucidation of Diagnostic and Statistical Manual of Mental Disorders personality disorder features. In the first study, college students (n=198) completed the Coolidge Axis II Inventory [CATI; Coolidge, F. L. (1999), Coolidge Assessment Battery Manual. Port Huron, MI: Sigma Assessment Systems and Coolidge, F. L., & Merwin, M. M. (1992). Reliability and viability of the Coolidge Axis II Inventory: a new inventory for the assessment of personality disorders. Journal of Personality Assessment, 59, 223–238] and Cohen's 1967 35-item test [Cohen, J. B. (1967). An interpersonal orientation to the study of consumer behaviour. Journal of Marketing Research, 4, 270–278] of Horney's three types: Compliant, Aggressive, and Detached. In the second study, another group of college students (n=881) completed the CATI and Coolidge's 57-item test of Horney's three types. Results showed that both scales were reliable, generally similar, and numerous predicted correlational relationships were found. The usefulness of Horney's constructs in the understanding of personality disorders was discussed. 相似文献
