We followed up over 90% of 57 motor vehicle accident survivors, who completed a controlled comparison of cognitive behavioral therapy (CBT) to supportive psychotherapy (SUPPORT). One-year results showed a continued significant advantage on categorical diagnosis (PTSD or not) and structured interview measures (CAPS) for CBT over SUPPORT. Other measures generally showed the same results. At two years, we were able to follow-up only 75% of one-year completers. Although there continued to be arithmetic differences favoring CBT over SUPPORT, with these attenuated samples only differences on PTSD Checklist and Impact of Event Scale scores and in overall categorical diagnoses were significant. There was very modest improvement from end of treatment to the two-year follow-up. 相似文献

A model for absolute judgment is presented. This is derived from a theory of the processes which set and maintain response criteria (M. Treisman & T. C. Williams, 1984, Psychological Review, 91, 68–111) which has been applied to a number of problems in psychophysics. A Thurstonian model is assumed as a basis for absolute judgment, and criterion-setting theory is applied to the criteria in this model. The question is then considered, to what extent can such a model account for the main findings that have been obtained in category scaling? The range of explanations that the model can provide is investigated by means of computer simulation. It appears that features such as the upper limit on information transmission as the number of stimuli increases, the effect of stimulus range on information transmission, the accuracy edge effect, the resolution edge effect, the central tendency of judgment, stimulus and response dependencies, and related phenomena can be reproduced by simulations of the model. 相似文献

Working hours, job stress, work satisfaction, and accident rates among medical practitioners and allied personnel 总被引:1,自引:0,他引:1

Predictors of accident behavior among German medical staff revealed that work-related injuries/accidents experienced during
a recent 12-month period were significantly related to working hours per week, distance from home to practice, number of dependent
children, gender, and job-related stress. The average yearly number of car accidents was predicted by age and number of working
hours. Furthermore, driving accidents going to or coming from work during the last year was determined by working climate,
hours of work, length of lunchtime break, distance traveled to and from work, number of dependent children, and gender. Physicians
working in excess of 48 hours per week displayed significantly more driving accidents but not work-related accidents, and
they reported significantly higher levels of job-related stress than those colleagues working fewer than 48 hours per week.
The implications of these results are discussed in the framework on risk management in the health services. 相似文献

Developmental changes in the interaction between word order and structural cues was investigated by having Hebrew-speaking children between 4 and 10 years of age interpret NVN utterances that balanced the complementary and contradictory effects of work order and two types of morphological cues, inflections that mark subject-verb gender agreement and an object particle. In Hebrew, gender inflections are highly complex and irregular while the object particle is highly regular and distinctive. Both word order and structural cues affected interpretations by subjects of all age groups, though the role of structural cues increased with age. For all groups, the objec particle was a dominant cue. The likelihood of assigning the agent relation to the first or second noun systematically varied with the relative weights of cues that supported and opposed each assignment. Comparisons were made between processing of Hebrew and processing of Serbo-Croatian and Turkish. 相似文献

Twenty-one normally developing 3-year-old children were tested on two approximant consonant contrasts, rake-lake and wake-rake, and a control contrast, wake-bake. Perception was assessed in a two-choice picture identification paradigm; stimuli were (1) natural and computer synthesized “clear cases” of the minimal pairs, and (2) synthetic stimulus series which interpolated on acoustic dimensions that differentiate the minimal pairs. As a group, the children showed very accurate perception of the minimal pairs. Performance on the synthetic series yielded consistent identification of the endpoint stimuli and monotonic functions with abrupt crossovers at the phoneme boundary. Children who did not yet articulate /r/ and /l/ appropriately showed somewhat less consistent perception than children who produced all phonemes correctly. 相似文献

Two experiments examined semantic elaboration and interpretation in recognition memory of 4-year-olds and college students. Subjects were presented pictures of color-specific and non-color-specific items, and then tested for their recognition of the chroma of the items. In Experiment 1, one-half of the presentation items were black and white and one-half colored, and testing always involved one black and white and one colored choice. In Experiment 2, all of the presentation items were colored, and testing always involved two colored choices. In both studies, the pattern of results of the two age groups was similar. Experiments 1 and 2 indicated that recognition judgments were based on representations that were elaborated with preexperimentally acquired semantic color information, and Experiment 2 also indicated that recognition judgments were based on representations that contained interpretive information about the appropriateness of the colors of the items. The results were considered to support and extend the view that when young children and adults share a common knowledge base, they are likely to engage in similar and extensive semantic processing. 相似文献

The effect of presentation context on the organization and recall of strongly related and weakly related words was examined in EMR adolescents and nonretarded fifth-grade children of the same mental age (131 months). In blocked presentation formats, subjects sorted words into experimenter-defined groups of four, in which the order of the groupings either changed from trial to trial (i.e., blocked-random), or was consistent across trials (i.e., blocked-consistent). In sort-prompt conditions, subjects were free to structure their own relationships among items during presentation, following instructions to form meaning-based groups (i.e., minimum-sort-prompt), or given explicit training in sorting categorization and sorting stability (i.e., maximum-sort-prompt). Both subject groups found the minimum-sort-prompt method to be as effective as the maximum-sort-prompt method for improving measures of recall and clustering relative to the blocked-random method. Nevertheless, nonretarded children showed higher levels of organization for strongly related items, and better recall and organization for weakly related items. Subsequent analyses suggested that the lower memory performance of the EMR individuals receiving weakly related items was the result of both inconsistent and poorly structured sorting schemes across trials. 相似文献

Two experiments are described in which subjects studied made-up, fantasy facts about well-known persons and then were asked to verify actual facts about these persons. Reaction time to the actual facts was longer the more fantasy propositions studied about a person. Reaction time was also longer when the verification test involved a mixture of actual and fantasy facts rather than just actual facts. A mathematical version of the ACT model (Anderson, 1976) was fit to the data. It provides a satisfactory fit, better than an alternate model. However, some of the parameter values estimated for the ACT model seemed unreasonable. 相似文献

Three experiments, investigate companion influences on humorous laughter and smiling. Boys and girls, aged 7 to 9 years, were played humorous recordings through headphones in dyadic and solitary conditions. Experiment I demonstrates that social facilitation effects in laughter and smiling reported in Chapman (1973) generalize to cases where a 2-year age/status difference exists between naturalistic coactors. In Experiments II and III companions were confederates, 2 years senior to subjects. They responded to directions relayed through headphones (coaction conditions) or a concealed speaker (audience conditions). It is shown in Experiment II that subjects' laughter, smiling, and looking are facilitated by increases in the laughter and smiling of coactors and, in Experiment III, that audiences are less effective in promoting high levels of responses. While increments in the coactor's looking enhance smiling and looking, corresponding increases in laughter are not statistically significant. Humor-ratings are associated with behavioral responses in Experiment II, but not Experiment III. Interaction data and results from subsidiary conditions are discussed. 相似文献
