Two simple classes of mastery scores which are suitable for hand calculations are presented for beta-binomial test score distributions
combined with linear and cubic referral success. The models provide a simple way to explore the consequences of selecting
an arbitrary mastery score. Such assessment would be useful whenever the test user is not willing to posta priori a loss ratio, but wishes to look at the various consequences before aiming at a particular score. 相似文献

Clinical training in psychology rarely includes the opportunity for students to exercise managerial responsibility for a functioning human service organization. Nevertheless, many clinicians are called upon to assume such decision-making duties, despite their lack of administrative training. This study examines the feasibility of using a computer model of a typical Community Mental Health Center (CMHC) as a training device, permitting clinical students to “manage” a complex social agency over a course of many months of simulated time. The system provides a valuable and interesting supplement to the usual training materials in psychology programs. 相似文献

Investigating instances where lexical selection fails can lead to deeper insights into the cognitive machinery and architecture supporting successful word retrieval and speech production. In this paper, we used a multiplex lexical network approach that combines semantic and phonological similarities among words to model the structure of the mental lexicon. Network measures at different levels of analysis (degree, network distance, and closeness centrality) were used to investigate the influence of network structure on picture naming accuracy and errors by people with Anomic, Broca's, Conduction, and Wernicke's aphasia. Our results reveal that word retrieval is influenced by the multiplex lexical network structure in at least two ways—(a) the accuracy of production and error type on incorrect productions were influenced by the degree and closeness centrality of the target word, and (b) error type also varied in terms of network distance between the target word and produced error word. Taken together, the analyses demonstrate that network science techniques, particularly the use of the multiplex lexical network to simultaneously represent semantic and phonological relationships among words, reveal how the structure of the mental lexicon influences language processes beyond traditionally examined psycholinguistic variables. We propose a framework for how the multiplex lexical network approach allows for understanding the influence of mental lexicon structure on word retrieval processes, with an eye toward a better understanding of the nature of clinical impairments, like aphasia. 相似文献

Imagined contact can be effective at reducing social stigma. However, the effect may depend on the strength of the stigma held. We tested the robustness of imagined contact in an Asian setting where stigmatization of mental illness is stronger than in Western countries. In Experiment 1 (n = 167) with five conditions, only an enhanced version of positive imagined contact was able to decrease stigma towards people with schizophrenia through decreasing intergroup anxiety. Given the potential discrepancy between imaginations and reality about experiences with stigmatized groups, in Experiment 2 (n = 121), we tested the hypothesis that after presenting participants with factual information about a mental illness group, imagined contact might backfire, resulting in more negative perceptions. However, enhanced imagined contact alongside factual message about schizophrenia did not increase stigma. The backfiring hypothesis was therefore not supported. Nevertheless, providing realistic information did negate the positive effects of enhanced imagined contact on stigma reduction. In both experiments, we also showed that intergroup anxiety mediated the effect of enhanced imagined contact on various measures of stigma. 相似文献

The present study evaluated the singular and interactive effects of a functional polymorphism (variation) in the serotonin transporter (5-HTT) gene and a psychological trait (anxiety sensitivity [AS], i.e., fear of arousal symptoms) in predicting subjective and physiological responses to a 35% carbon dioxide (CO2) challenge in a community sample (N = 72). Genotypes were divided into 2 groups in accord with prior research. Findings were partially supportive of the hypothesized risk model. These indicated that the Group L genotype (homozygous for the 1 allele), compared with the Group S genotype (homozygous for the s allele plus heterozygous individuals), predicted greater fearful response to the biological challenge. There was also an AS x Genotype interaction predicting heart rate variability (HRV) in response to the CO2, suggesting that high AS plus Group L status predicts decreased HRV. 相似文献

We examine a shape illusion, in which the balconies of a building appear to tilt up or down, depending on the viewpoint. The balconies are actually level parallelogram shapes, but appear as tilted rectangles. We measured the illusory tilts observed when parallelogram shapes are viewed above the line of sight, using three-dimensional stimuli consisting of parallelograms of various tilts viewed at different orientations. Under perspective projection, parallelism and orthogonality are not preserved. However, perspective distortions alone cannot account for the perceived tilts measured in these experiments, since observers perceived illusory tilts even for stimuli in the frontoparallel plane. We introduce a model, based on the theory that observers assume ambiguously projected three-dimensional angles to be equal to 90 degrees, but revise their predictions on the basis of observation. In the model, perceived tilt is predicted as a weighted sum of the tilts predicted by the assumptions that the shape is rectangular, and that the shape is level (i.e. that the angle between the shape and the vertical backboard is equal to 90 degrees). We prove that it is mathematically impossible for a planar rectangle to share a projection with a nonrectangular parallelogram. A less restrictive assumption that just the two leading internal angles are equal to 90 degrees is suggested as an alternative, and it is further proven that this new configuration of angles leads to a unique perceived tilt. The relative weights in the model reflect the amount that each prediction is revised, and are shown to vary systematically with stimulus orientation. For some observers a better fit was found by replacing the level-tilt assumptions with an assumption that physical tilt was equal to the projected tilt. 相似文献
