This article acknowledging and celebrating William Barr Oglesby, Jr. as Pastoral Theologian of the Year for 1983, was originally published inPastoral Psychology 32(1) in Fall, 1983. As a result of some errors that inadvertently modified both the tone and the meaning of the text, we are republishing this article here in its entirety.  相似文献

This study examined the validity of a rationally developed biographical questionnaire for predicting content valid test performance for electrician applicants ( N = 221). Job analysis task statements were utilized as biographical items, and applicants were required to rate their previous work experience regarding each task. The utility of the questionnaire in screening applicant populations was shown to be both statistically and practically significant. EEOC implications are discussed.  相似文献

The stability of oral and nonoral vibrotactile magnitude scales produced by the method of magnitude production was investigated for 11 adult subjects. Each subject was tested over four sessions separated by 1-wk. intervals. Data analyses included correlations across trials of power function slopes as well as individual adjustments of intensity. Analysis showed a lack of stability over time for the slope functions obtained on the thenar eminence but moderate stability for the functions obtained on the tongue. Individual adjustments on intensity showed consistently high correlations across trials and structures. It was concluded that the subjects' responses were guided by the imposed experimental variables and that each individual's scaling was not necessarily reflected by the correlations based on power function slopes established over the four trials.  相似文献

A double-blind experiment with 58 adults tested the hypothesis that proximity to sugar reduces human grip strength. An analysis of variance supported the hypothesis.  相似文献

This paper presents the results of an in-depth study of parameters characterizing sequenced saccadic eye movements for a group of dyslexic children and a comparative normal control group with ages in the range greater than 8.0 yr. and less than 13.0 yr. No parameters were statistically different for the two groups, which supports the findings of Brown, et al. and contradicts the findings of Pavlidis. Our results indicate that sequenced saccadic eye movements are not diagnostically useful for early detection of dyslexia.  相似文献

Lingual fusion thresholds for a two-pulse stimulus were obtained at a 15-dB sensation level and a 35-dB sensation level for 15 subjects (18 to 22 yr.). The 35-dB sensation level provided better temporal resolution thresholds as well as less variable responses.  相似文献

Tachistoscopic presentation of light flashes was used to test for differences in visual sensitivity among 3 groups of practitioners of Buddhist mindfulness meditation and non-meditator-controls. Meditation practitioners were able to detect light flashes of shorter duration than the non-meditators. There were no differences among the meditator groups. There were no differences among the groups in ability to discriminate between closely spaced successive light flashes. The lower detection threshold for single light flashes for the meditators may reflect an enduring increase in sensitivity, perhaps the long-term effects of the practice of mindfulness meditation on certain perceptual habit patterns. The lack of significant differences in the discrimination of successive light flashes probably reflects the resistance of other perceptual habit patterns to modification. The results support the statements found in Buddhist texts on meditation concerning the changes in perception encountered during the practice of mindfulness.  相似文献
