Diagnosis can be a process that helps organizations enhance their capacity to assess and change dysfunctional aspects of their culture and patterns of behavior as a basis for developing greater effectiveness and ensuring continuous improvement. The authors set forth a framework for understanding what can be called a “learning diagnosis” in which the diagnostic process is part of a large-scale organizational revitalization effort. In particular, they explore how the diagnostic intervention is affected by the diagnostic consultant, by the top management sponsors of the intervention, and by the process of collecting and acting on data. They conclude with a discussion of both the opportunities and challenges of institutionalizing the learning diagnosis process. 相似文献

It has long been known that the pupil dilates as a consequence of attentional effort. But the function that relates attentional input to pupillary output has never been the subject of quantitative analysis. We present a system analysis of the pupillary response to attentional input. Attentional input is modeled as a string ofattentional pulses. We show that the system is linear; the effects of input pulses on the pupillary response are additive. The impulse response has essentially a gamma distribution with two free parameters. These parameters are estimated; they are fairly constant over tasks and subjects. The paper presents a method of estimating the string of attentional input pulses, given some average pupillary output. The method involves the technique of deconvolution; it can be implemented with a public-domain software package, Pupil. 相似文献

In 1984, the National Science Foundation began a large initiative to provide the scientific community with access to Class VI computers. With the support of the NSF Program on Memory and Cognitive Processes, the Federation of Behavioral, Psychological and Cognitive Sciences invited a group of scientists to a workshop that considered the advanced computational needs of several areas of psychological, behavioral, and cognitive sciences. This paper presents a summary of the conference deliberations. 相似文献

It was demonstrated that variations in the informativeness of a social stimulus place important limitations on the generality of the proposition that deprivation heightens, while satiation lowers, responsiveness to a social stimulus. Using 60 children 5 to 6 years of age as subjects, a social stimulus (“good”) was presented at either a high or a low frequency in one of three information-value contexts (high, medium, or low). Immediately following the exposure treatment the same social stimulus was employed as a reinforcer of nonpreferred responses in a two-choice discrimination learning task. The findings indicated that the heightened efficacy of deprivation relative to satiation only held for low information value; when initial information value was high the subsequent efficacy of a social stimulus was enhanced by its initial recurrent usage. Trend analyses revealed that the effects of variations in information value were strongest within the high-frequency-of-praise treatment. Possible mechanisms underlying the significant Information Value × Frequency interaction were discussed. 相似文献

Previous findings of correlations between mood and personality variables were noted. It was suggested that the establishment of a causal relationship was crucially important, not merely to the understanding of how mood is related to personality but to the conceptualization of mood as a source of error in personality measurement as well. A prior attempt to establish a causal role for mood failed, but may have done so for methodological reasons. The present study investigated the influence of a mood manipulation on personality measures. There was also an opportunity to replicate prior correlational findings independent of the effect of the mood manipulation. College students were asked to think of happy, sad, or affectively neutral events and then filled out several personality measures. A manipulation check confirmed that different moods were induced by this procedure. The prior correlations between mood and personality variables were replicated, but the mood manipulation did not affect any of the personality measures. The implications of these results for personality measurement and for the relation between mood and behavior were discussed. 相似文献

What i think and feel: A revised measure of children's manifest anxiety 总被引:31,自引:0,他引:31
The 1956 adaptation for children of Taylor's Manifest Anxiety Scale, the Children's Manifest Anxiety Scale, was revised to meet current psychometric standards. A 73-item revision draft was administered to 329 school children from grades 1 to 12. Based on item-analysis criteria for rbis.4 and .30p.70, 28 anxiety items were retained along with 9 of the original 11 Lie scale items. A cross-validation sample of 167 children from grades 2, 5, 9, 10, and 11 produced a KR20 reliability estimate of .85. Anxiety scores did not differ across grade or race. Females scored significantly higher than males. For the Lie scale, significant differences appeared by grade and race. No sex differences were obtained on the Lie scale. The resulting scale appears useful for children in grades 1 to 12 and may aid in future studies of anxiety as well as assisting the clinician in the understanding of individual children. 相似文献

Various methods of implementing a computer-based tachistoscope are compared. Software considerations are emphasized, but hardward issues are also examined. Three types of systems are identified: file-driven systems, sets of callable subroutines, and special languages. All have advantages in some circumstances. A system of callable subroutines is favored, together with a file-driven system written in the host language using the subroutines. 相似文献

One of the causes of agoraphobic complaints is the fear of having an attack of physical complaints in public places. The Hyperventilation Syndrome (HVS) with its diverse symptoms seems to fit well in this model. Hyperventilation symptoms are threatening, because for most subjects they occur unexpectedly and without a clear reason. An investigation was made into how often the HVS and the agoraphobic syndrome appeared together and into the causal relationship between both syndromes. About 60% of the agoraphobic patients suffered from hyperventilation complaints and about 60% of the HVS patients were agoraphobic. Most patients mentioned the fear of having an attack as an important reason for their agoraphobic complaints, and this applied especially in the case of the HVS. 相似文献
