The paper is an attempt to point out that the literature of existential philosophy has produced a meaningful theory of vocational development. The theory not only appears to be cogent, but also lines up closely with current thinking in the field. The contrast with various authors is an attempt to illucidate through similarity the ultimate ramifications of the existential theory. An equally important aspect of this theory is that within it one discovers an explanation of work alienation. Finally, there is every reason to believe that the existentialists have produced only a small portion of the potential theoretical model.  相似文献

Our intuition that we richly represent the visual details of our environment is illusory. When viewing a scene, we seem to use detailed representations of object properties and interobject relations to achieve a sense of continuity across views. Yet, several recent studies show that human observers fail to detect changes to objects and object properties when localized retinal information signaling a change is masked or eliminated (e.g., by eye movements). However, these studies changed arbitrarily chosen objects which may have been outside the focus of attention. We draw on previous research showing the importance of spatiotemporal information for tracking objects by creating short motion pictures in which objects in both arbitrary locations and the very center of attention were changed. Adult observers failed to notice changes in both cases, even when the sole actor in a scene transformed into another person across an instantaneous change in camera angle (or “cut”).  相似文献

The Diana (Diana v. State Board of Education, Note 1) and the Larry P. (Larry P. v. Riles, Note 2) litigations led to decertification of thousands of California EMR students and their return to the regular program. Allegations, including those of biased testing, went largely uncontested in order that change in special education could result from court mandate, but the allegations left the psychologists in a libeled state. A study of cumulative records and psychologists files in 12 representative districts permitted a comparison of the EMR placement of those later decertified (D) with matched nondecertified (EMR). Other than a small mean difference in IQ at placement, nothing was found to support various allegations. Records showed no systematic differences betweeen D and EMR groups in pre-EMR reasons for referral nor in teacher marks, discnfirming beliefs in referral of higher functioning students for deportment rather than for academic failure. Districts permitted a mean of at least two years in regular placement before assessment, attesting to class failure rather than IQ as the initial and necessary basis for EMR identification (no D-EMR difference in this either). The data permit a conclusion that the work of the school psychologists in the EMR placement was professionally competent, given the guidelines in effect at the time.  相似文献

Some effects of positive life events on community mental health   总被引:1,自引:0,他引:1  
Measures of positive and negative events were derived from a life-event inventory to test the predictions of an equilibrium model and a positive mental health model of psychological well-being. These measures were related to indicators of individual and community well-being with data obtained through a household survey of 454 residents. Residents who reported more negative events also reported more psychological distress and less positive adjustment. Positive events were associated with reports of positive adjustment. An analysis of census tract scores on life events revealed that the relative absence of positive events in census tracts was associated with higher service utilization rates to the community mental health center serving those tracts. The number of negative events was unrelated to service rates for census tracts but was related to several demographic indicators of well-being.  相似文献

A preparation for the experimental analysis of cigarette smoking is described in detail. The preparation permits the intensive study of cigarette smoking in individual subjects under controlled laboratory conditions. A variety of behavioral and physiological measures used include rate and pattern of puffing, duration of each puff, time spent smoking cigarettes, expired air carbon monoxide levels, cigarette butt weights, and subjective rating scales of various aspects of smoking. The preparation is reliable and permits relatively unobtrusive monitoring of smoking performance. Cigarette smoking occurs in orderly patterns, within subjects; it varies as a function of number of cigarettes provided and hours of smoking deprivation.  相似文献

Recent studies suggest that religion and spirituality can yield health benefits for young African-Americans. We examined the relationship between religious practices, spirituality, and excess weight among African-American adolescents (N = 212) residing in the Deep South. Results from modified Poisson regression analysis indicate that adolescents who prayed daily had a lower prevalence of excess weight (PR 0.77 [95% CI 0.62–0.96]) than those who did not. This relationship was only significant for 12–15 year-old participants in age-stratified analysis. These findings suggest that preventive interventions offered to children and younger adolescents can have implications for weight status across the lifespan.
