The psychological stress reactions of 44 family medicine patients who were treated in the emergency room were examined approximately a year after the event. Patients were assessed on several psychological measures, including one for posttraumatic stress disorder (PTSD), and on their perception of how stressful the event was initially and now. Results show continuing stress reactions related to the emergency room event. Three patients endorsed symptoms indicating full PTSD and 13 appeared to have at least partial PTSD. Age appeared to be a factor in the presence of stress symptoms and in degree of perceived communication with the physician.  相似文献

Behavior analytic evaluation instruments should benefit teacher education programs in assessing: (a) teacher and student interactions in practice teaching settings, and (b) the immediate and long range effects of the teacher training received. Though empirical substantiation remains scarce, such instruments may be designed to foster teacher trainee sensitivity to, and better control of, complex stimulus and response mechanisms which either impede or facilitate learning. This study analyzed one technologically driven Behavior Analysis Strategy and Taxonomy (BEST) and related Temporal Analysis System (TAS) (Hawkins, Sharpe, & Ray, 1994) currently used within one preservice teacher education program. A multiple probe design with experimental and control groups demonstrated the instruments' effects when used as an instructional feedback tool with teachers in training. Findings supported the instruments' use in terms of teacher and student behavior changes demonstrated for the experimental group as compared to a control group not exposed to the instrument. Implications of this technology when applied to teacher education are last described.  相似文献

Three experiments examined repetition priming for meaningful environmental sounds (e.g., clock ticking, tooth brushing, toilet flushing, etc.) in a sound stem identification paradigm using brief sound cues. Prior encoding of target sounds together with their associated names facilitated subsequent identification of sound stems relative to nonstudied controls. In contrast, prior exposure to names alone in the absence of the environmental sounds did not prime subsequent sound stem identification performance at all (Experiments 1 and 3). Explicit and implicit memory were dissociated such that sound stem cued recall was higher following semantic than nonsemantic encoding, whereas sound priming was insensitive to manipulations of depth encoding (Experiments 2 and 3). These results extend the findings of long-term repetition priming into the auditory nonverbal domain and suggest that priming for environmental sounds is mediated primarily by perceptual processes.  相似文献

This comment responds to an article by Range and Cotton (1995) on reporting of parental permission and child assent procedures in published articles for 4 psychology journals. Issue is taken with the assumptions, methodology, interpretations, and implications of listing researchers in the Range and Cotton article. There is no evidence researchers failed in their ethical obligations or that children were put at risk. Reporting permission/assent in publications is not an ethical requirement. Listing researchers as "failing" to do something not part of an ethical code is lamentable. Too many unfortunate implications and problems can be derived from Range and Cotton's analysis and conclusions.  相似文献
