During much of the past century, it was widely believed that phonemes—the human speech sounds that constitute words—have no inherent semantic meaning, and that the relationship between a combination of phonemes (a word) and its referent is simply arbitrary. Although recent work has challenged this picture by revealing psychological associations between certain phonemes and particular semantic contents, the precise mechanisms underlying these associations have not been fully elucidated. Here we provide novel evidence that certain phonemes have an inherent, non-arbitrary emotional quality. Moreover, we show that the perceived emotional valence of certain phoneme combinations depends on a specific acoustic feature—namely, the dynamic shift within the phonemes' first two frequency components. These data suggest a phoneme-relevant acoustic property influencing the communication of emotion in humans, and provide further evidence against previously held assumptions regarding the structure of human language. This finding has potential applications for a variety of social, educational, clinical, and marketing contexts. 相似文献

The purpose of the present study was to assess the between-measure consistency of general and specific social-skills assessment strategies. Nineteen mentally retarded adults were assessed using both common and newly devised measures of social skills: (1) specific (molecular) behavior ratings from role-play assessments, (2) general (molar) ratings based on the role plays, staff (3) molar and (4) molecular predictions of client social skills use in the described role-play situations, (5) peer sociometric ratings, and molecular in vivoobservations conducted in (6) cafeteria and (7) party settings. For all molecular measures, the subjects were assessed on eye contact, response relevance, response latency, voice volume, and appropriate affect, which allowed for direct comparisons to be made between each of these assessment modalities. In addition, the role-play assessment was conducted under two distinct conditions to determine whether role-play performance varied between standard and reinforced administrations; however, multivariate analyses (MANOVA) revealed no differences between the two assessments. Correlations between the molar and the molecular measures suggested a substantial overlap between the measures, with staff ratings having the highest consistency with the other measures. Furthermore, MANOVAs calculated between role-play ratings and those of staff revealed little difference between the two. The limitations on and practical significance of these findings are discussed. 相似文献

Proactive Socialization and Behavioral Self-Management 总被引:1,自引:0,他引:1
The purpose of this study was to examine behavioral self-management as a form of newcomer proactive socialization behavior. A longitudinal field study was conducted with a sample of 153 entry-level professionals who completed questionnaires during their first month of entry and 6 months after entry. The results indicated that self-management behavior was related to newcomers’ general anxiety and stress at entry, and to internal motivation, ability to cope, and task-specific anxiety 6 months later. In addition, anxiety and stress at entry were found to mediate the relationships between self-management and ability to cope and task-specific anxiety. The research and practical implications of these findings are discussed. It is recommended that future research integrate the self-management and information seeking perspectives to provide a more complete theory of proactive socialization. 相似文献

Organizers of the Human Genome Project (HGP) understood from the beginning that the scientific activities of mapping and sequencing the human genome would raise ethical, legal, and social issues that would require careful attention by scientists, health care professionals, government officials, and the public. The establishment of the ELSI (ethical, legal, and social implications) programs at the National Human Genome Research Institute (NHGRI) and the Department of Energy (DOE) was thought to be vital to the success of the HGP in the United States. It also provided a novel approach to the simultaneous study of ethical, legal, and social issues and basic scientific issues. Eric Juengst, the first director of the ELSI program, described its origins in a previous issue of the Kennedy Institute of Ethics Journal (Juengst 1991). Now in its seventh year, the ELSI program has accomplished much. This article summarizes the evolution and goals of the ELSI program at NHGRI, outlines the program's current research priorities with examples of activities within each priority area, and provides a look to the future, including the initiation of a strategic planning process. 相似文献

When viewing a pair of bars defined by the difference of spatial Gaussian functions (DOGs), human observers can discriminate accurately the relative movements of the bars, even when they differ in spatial frequency. On each trial, observers viewed two brief presentation intervals in which a pair of vertically oriented DOGs moved randomly back and forth within a restricted range. During one interval, both bars moved in the same horizontal direction and by the same magnitude (correlated movements); in the other interval, their movements were uncorrelated. When discrimination accuracy is related to the simultaneous detection of two independent movements, it was found that, if observers can detect the movements of spatially separated bars, they can tell whether their relative movements are correlated. Performance remained remarkably accurate even when the two bars differed in spatial frequency by more than two octaves or were presented separately to the two eyes. Apparently, the accurate discrimination of coherent motion involves an efficient spatial integration of optical motion information over multiple spatial locations and multiple spatial scales. 相似文献

Experiments that compare monocular and binocular visual performance of human psychophysical Os on a variety of visual tasks are reviewed. The review attempts to include all experiments published in English in this century, excluding work on stereopsis, rivalry, and evoked potentials. The concept of probability summation as a baseline for assessing the presence of neural summation is discussed, and the assumptions of several models for estimating probability summation are considered. Experiments are classified in terms of visual task, major categories being increment detection, flicker fusion, brightness magnitude, and contour resolution. A major conclusion is that binocular performance is superior for essentially all task categories and in most cases by a magnitude greater than that predicted by appropriate probability summation models. 相似文献
