A visual acuity testing procedure is described which uses a self-adjustment procedure combined with shock avoidance and punishment. The S adjusts the size of the gap opening in Landolt rings by pressing levers. Correct trials decrease the size of the gap opening and are followed by a tone; incorrect trials increase the size of the gap opening and are followed by shock. The number of correct and incorrect trials needed to change the gap-opening size can be varied. 相似文献

High and low visual imagers, defined as such primarily on the basis of spatial manipulation test performance, were required to identify tachistoscopically-presented pictures, concrete words, and abstract words varying in familiarity. Two recognition paradigms were employed, recognition threshold and recognition latency. High imagers were faster in picture recognition under both paradigms when a nonverbal set or strategy was primed and when pictures were relatively unfamiliar in the threshold paradigm. No relationship was found between imagery ability and word recognition in the visual modality, nor was visual imagery ability related to the auditory recognition of verbal and nonverbal stimuli, such as words and environmental sounds. Commonalities between these findings and others in the imagery ability literature were noted. 相似文献

Tests purporting to reflect the learning aptitudes of school children differ much more than generally is recognized. However, error in assesing such learning aptitude inheres much more in the users of the tests than in the tests themselves. Assumptions fundamental to such assessment, or even testing, are considered. It is particularly important that the assessor, or tester, constantly be sensitive to the nature of the relationship between the psychological demands of test items or tests and the learning demands confronting the child. Even tests that generally are grossly or crudely used often can yield psychoeducationally meaninful information if their results are differentially perceived in terms of the light they throw on the psychological operations fundamental to learning, “process,” as contrasted with that thrown on the results of the functioning of such operations, “product.” 相似文献

Relations between selective attention and perceptual segregation by color were investigated in binary-choice reaction time experiments based on the non search paradigm of Eriksen and Eriksen (1974). In focused attention conditions (Experiment 1), noise letters flanking a central target letter caused less interference when they differed from the target in color, although color carried no information as to whether or not a letter was the target. When blocking of trials favored a strategy of dividing attention between target and noise letters (Experiment 2), no benefit accrued from difference between target color and noise color. The results supported an attentional interpretation of the effect of color demonstrated in Experiment 1, implying that perceptual segregation by color improved the efficiency of focusing attention on the target. 相似文献

The present study evaluated the efficacy of cognitive-behavioural skills training, patterned after stress-inoculation training, as a preventive intervention for the attenuation of acute clinical pain during a noxious X-ray procedure—the knee arthrogram. Thirty-six adult male outpatients were randomly assigned to one of three groups: Skills Training. Attention-Placebo, and No-Treatment Control. An experimental pain test was administered before and after the interventions, as a generalization measure. Arthrogram pain was assessed by three dependent measures: patient's ratings, radiologist's ratings and videotape ratings completed by two‘blind’ raters. The results failed to support the efficacy of skills training for the attenuation of acute clinical pain, or its generalization to the experimental pain test. Although Skills Training subjects reported using significantly more coping strategies during the arthrogram. many subjects in the two control groups also reported using their own spontaneous strategies. Equivocal data were obtained on the role of ‘self-efficacy’ expectancies in mediating pain behaviour and experience. Experimental pain threshold but not pain tolerance was significantly related to acute clinical pain experienced during the arthrogram. 相似文献

Different inferences in probabilistic logics of conditionals preserve the probabilities of their premisses to different degrees. Some preserve certainty, some high probability, some positive probability, and some minimum probability. In the first case conclusions must have probability 1 when premisses have probability 1, though they might have probability 0 when their premisses have any lower probability. In the second case, roughly speaking, if premisses are highly probable though not certain then conclusions must also be highly probable. In the third case conclusions must have positive probability when premisses do, and in the last case conclusions must be at least as probable as their least probable premisses. Precise definitions and well known examples are given for each of these properties, characteristic principles are shown to be valid and complete for deriving conclusions of each of these kinds, and simple trivalent truthtable tests are described for determining which properties are possessed by any given inference. Brief comments are made on the application of these results to certain modal inferences such as Jones may own a car, and if he does he will have a driver's license. Therefore, he may have a driver's license. 相似文献

Psychological problems (e.g., anxiety, depression, substance abuse) are prevalent in primary care medical settings. Family physicians (FPs) treat more patients than any other primary care medical specialists. Thus, FPs can play an extremely important role in providing psychological services to their patients. In contrast to other specialists (e.g., internists, obstetricians), FPs are required to complete behavioral science training in their residencies. In this paper, we describe standard undergraduate, graduate, and postgraduate training of FPs. We present our unique program for teaching psychological principles and skills to family practice residents at the University of Kansas Medical Center. And finally, we introduce an instrument, the Interview Rating Scale (IRS), for evaluating the interviewing skills of physicians and residents. 相似文献

This study examined the effects of reinforcement contingencies designed to increase the performance of existing reading skills as well as the effects of instruction—modeling and practice—designed to increase skill level for oral reading fluency across three levels of reading materials. Results showed that a combination of contingencies, modeling, and practice was effective in producing substantial increases in reading fluency for all participants at their assigned grade levels. These results demonstrate one strategy for experimentally determining those instructional components that are required to increase oral reading rate. 相似文献
