Three experiments were performed to explore the effects of mismatches between actions (key-presses) and the contents of auditory feedback (pitch events) during music performance. Pianists performed melodies from memory during altered auditory feedback that was synchronized with key-presses but matched the pitch of other sequence events. Feedback direction was manipulated by presenting pitches that matched events intended for the past (delays; Experiments 1 and 3) or the future (prelays; Experiments 2 and 3). Feedback distance was manipulated by varying the absolute separation between the current event and the location of the feedback pitch. All alterations disrupted the accuracy of performance (pitch errors) more so than timing. Serial-ordering errors indicated confusions among proximal and metrically similar events, consistent with the predictions of an incremental planning model (Palmer & Pfordresher, 2003). Patterns of serial-ordering errors suggested that performers compensate for the disruptive effects of altered feedback by changing event activations during planning. 相似文献

Accountability and need for cognition effects on contrast, halo, and accuracy in performance ratings
In the present study, the authors investigated the effects of accountability and need for cognition on contrast errors, halo, and accuracy of performance ratings examined in good and poor performance context conditions, as well as in a context-free control condition. The accountability manipulation reduced the contrast effect and also modified rater recall of good ratee behavior. Accountability reduced halo in ratings and increased rating accuracy in a poor performance context. Accountability also interacted with need for cognition in predicting individual rater halo. 相似文献

In Exp. I, shallow U-shaped gradients of inhibition in the line-orientation dimension were obtained from birds that had a vertical (0°) line on a green surround correlated with extinction and a blank green surround correlated with reinforcement. Birds that had massed extinction in the presence of the 0° line showed flat gradients. Thus, discrimination training, but not massed extinction, appears to generate inhibitory control. In Exp. II, as in studies of control by a stimulus correlated with punishment, non-differential training across the line-orientation dimension preceded further sessions. Steep inverted gradients about the 0° line were obtained after discrimination training with the 0° line correlated with extinction. Gradients obtained after massed extinction tended to be flat. Again, discrimination training was critical in obtaining negative gradients of stimulus control. 相似文献

This paper discusses the application of the principles of factorial design to an experiment in psychology. For the purpose of illustrating the principles, a simple experiment was designed dealing with the determination of the differential limen values of subjects for weights increasing at constant rates. The factorial design was of the type: 4 rates × 7 weights × 2 sexes × 2 sights × 2 dates. The appropriate statistical analysis for this type of design is the analysis of variance. The mathematical formulation of the problem was specified and the appropriate solution for the specific problem was obtained. Greater precision results from this type of design, in comparison with the traditional psychological experiment dealing with a single factor, in that measures are obtained of the effect of each of a number of factors together with their interactions.This is one of a number of studies on modern principles of experimental design. For the research grant to finance these studies, grateful acknowledgment is given to the Graduate School, the University of Minnesota. 相似文献

Job comparison research is critical to many human resources initiatives, such as transporting validity evidence. Job analysis methods often focus on critical attribute (e.g., tasks, work behaviors) overlap when assessing similarity, but profile similarity metrics represent an alternative or complementary approach for job comparisons. This paper utilizes Occupational Information Network (O*NET) data to establish a distribution of job profile correlations across all job pairs for five attributes – generalized work activities, knowledge, skills, abilities, and work styles. These correlations represent effect sizes, or degree of shared variance between jobs. Practitioners may reference these correlational distributions as benchmarks for gauging the practical significance of the observed degree of similarity between two jobs of interest compared to the broader world of work. 相似文献

This article seeks to set aside what we might call Cartesian physics to revisit William Durand's conception of sign as set forth in the Rationale divinorum officiorum and John Calvin's as set forth in the Institutio christianae religionis. Reading the two works through the lens of medieval physics reveals commonalities – both held signs to be ever-present modes of divine communication – and enables us to delineate more precisely their differences. For both, creation was a locus of divine communication. For Durand, the position of a faithful person was observation informed by Scripture, an attentiveness to the redundantia of divine communication in which Scripture and creation were in dialectic. For Calvin, divine communication was simultaneously visible and, to fallen humankind, imperceptible: even as creation held forth divine signs, human beings could not comprehend them. These differing conceptions of the human observer (Durand) or spectator (Calvin), precede and ground their differing approaches to eucharistic signs. 相似文献

The assertion by Baer and Lambert (1990) that social science training does not promote radicalism, is tested in two studies.
The first, using a sample of politically active students from Montréal (N=68) and measures of radical ideology and political
convictions, shows social science students are over-represented among politically active students, and more likely to espouse
radical ideology and label themselves members of groups aiming to restructure society, than students from other fields. The
second study compares first and third-year social science students from Toronto (N=99) on measures of radical ideology, attitudes
toward groups favouring change or the status quo, and causal attributions regarding poverty and unemployment. Results suggest
social science training fosters positive evaluations of groups seeking change, espousal of radical ideology, tendency to fault
the system for social problems, decrease in tendency to fault individuals, and development of a coherent ideological framework.
Implications for academic socialization theories and methodological issues are discussed.

Theories of skilled music performance must account for variations on what is written in traditional musical notation. Some variations are intentional and reflect structural features of the music that are chosen for emphasis by the performer. Current music notations are inadequate to reflect these variations. Computer applications are described that allow graphical and statistical examination of performance variations on traditional musical notation. An integrated set of visual and sound tools is provided that allows music to be recorded, edited, analyzed, and played back on electronic and acoustic musical instruments. The graphical format allows flexibility through the use of windows, compression, expansion, and scrolling of multiple sources of information, mapping of acoustic to visual dimensions, and scaling of different performance parameters without normalization. Experimental evidence from piano performances is used to demonstrate how graphical formats can aid research on human performance. 相似文献

Because crack use is such a recent phenomenon, little is known about users of this highly addictive drug, the harmful effects of which have been widely publicized. This study hypothesized that crack users would be more depressed and more alienated from family, friends, and school staff than would cocaine users, and would consider as less important reasons not to use crack and cocaine. The authors compared 411 users of cocaine (but not crack) to 156 crack users, all but 22 of whom had also used cocaine. The sample was derived from a larger random survey of 7th- through 12th-grade students in North Carolina. Results indicated that crack users were younger than cocaine users, made poorer grades, were more depressed, and were more likely to be alienated from family and friends. However, cocaine and crack users were equally unlikely to confide in anyone in their school if they had a drinking or drug problem. Further, crack users were more likely to have talked once to a teacher or counselor in the past year about their problems. The implications of these seemingly inconsistent findings are explored. Crack users appear to be a particularly vulnerable population. 相似文献
