This paper compares the determination of optimal cutoff points for single and multiple tests in the field of personnel selection. Decisional skills of predictor tests composing the multiple test are assumed to be endogenous variables that depend on the cutting points to be set. It is shown how the predictor cutoffs and the collective decision rule are determined dependently by maximizing the multiple test's common expected utility. Our main result specifies the condition that determines the relationship between the optimal cutoff points for single and multiple tests, given the number of predictor tests, the collective decision rule (aggregation procedure of predictor tests' recommendations) and the function relating the tests' decisional skills to the predictor cutoff points. The proposed dichotomous decision-making method is illustrated by an empirical example of selecting trainees by means of the Assessment Center method. 相似文献

Dizziness is a common and often untreated symptom in the general population. The aim of this study was to investigate the effects of a combined cognitive-behavioral/vestibular rehabilitation (VR) program, using a randomized control design. A total of 29 participants were randomized to treatment consisting of psychoeducation, vestibular exercises, relaxation and cognitive interventions, or to serve as waiting list controls. Measures of dizziness-related handicap, dizziness-provoking movements, and daily diary registrations of dizziness symptoms at pre- and post-treatment showed statistically significant improvements in many domains, which translated to moderate effect sizes. These findings provide preliminary support for the combination of Cognitive-behavioral therapy (CBT) and VR methods in the treatment of dizziness. 相似文献

Ratings of age of acquisition (AoA), imageability, and familiarity were collected for 1,526 words. The methodology made use
of a modular approach, in which the full sample of words was divided into five separate blocks. Within each block, each word
was rated on each of the three variables by 20 participants (undergraduate students from the University of Bristol). Analyses
comparing these ratings to existing norm databases demonstrated that this methodology resulted in high reliability (assessed
by Cronbach’s α) and validity. The ratings were also transformed to be compatible with the Gilhooly and Logie (1980) norms.
This transformation resulted in a set of norms for 3,394 words, which is by far the largest database of ratings for AoA, imageability,
and familiarity to date. The resulting database should be useful for researchers interested in manipulating or controlling
these factors in word recognition, neuropsychological, or memory studies. These norms can be downloaded from language.psy.bris

Between 1919 and 1956, psychologists at the University of Toronto built a research program in developmental psychology on a functionalist, holistic, and ecological basis. They conducted longitudinal studies on mental health in growing children in educational settings instead of in laboratories and formed strong alliances with the local educational system in order to do so. They initially defined mental health as adjustment and considered conditions within schools to be conducive to its attainment. After developing a psychological theory of personality development, they came to view educational conditions as discouraging the development of mental health. The alliance between the educational system and psychology consequently unraveled, and the program declined. 相似文献

Adaptation experiences of 1.5-generation Asian American college students (N = 10) were examined using the consensual qualitative research method. Results indicated 4 domains of adaptation experiences: preimmigration experiences, acculturation and enculturation experiences, intercultural relationships, and support systems. Participants reported that English proficiency played a significant role in their initial adjustment. Currently, most of the participants reported feeling identified with both the U.S. and Asian cultures. Some participants reported having experienced racism in the past. Many participants noted that they currently have no difficulty establishing friendships with culturally different persons. Participants reported currently feeling most close to friends of a similar background and that they usually seek support from friends, family, and religious organizations, but not from a psychologist or counselor. 相似文献

To investigate amnesia between identities in dissociative identity disorder (DID), the authors assessed explicit and implicit memory performance on a directed-forgetting task in 12 DID patients who switched from one state to an "amnesic" state between presentation and memory testing. DID patients were instructed either to remember or to forget neutral and emotional words. Besides an overall decrease in explicit memory, patients demonstrated selective forgetting of to-be-forgotten, but not of to-be-remembered words in the amnesic state. Patients did not exhibit any directed forgetting within the same state. Implicit memory was fully preserved across states. Independent of state, patients recalled more emotional than neutral information. These results may extend the conceptualization of memory processes in DID, suggesting an important role for retrieval inhibition. 相似文献

Patients with Parkinson's disease (PD) have repeatedly demonstrated reduced sequence-specific learning effects in serial reaction time tasks (SRTs). Previous research with PD patients has mainly employed the 'classical' SRT task, involving a spatially compatible assignment of stimuli and responses. From cognitive research, it is known that spatial compatibility triggers rapid, automatic responses in the direction of the stimulus. Automatic responding has shown to be disinhibited in PD patients and may therefore interfere with stimulus anticipation during the learning process. The aim of the present study was to test this hypothesis by investigating if reduced sequence-specific learning depends on spatial stimulus-response compatibility. PD patients and age-matched controls were examined either with an SRT variant involving central stimulus presentation, thereby preventing automatic linking of stimulus and response locations, or with a spatially compatible SRT task. Patients showed reduced sequence-specific learning effects only when the stimulus-response assignment was spatially compatible. This pattern of results confirms the hypothesis that sequence learning deficits in PD may result from a predominance of automatic response activation over learning-based stimulus anticipations during the learning phase. 相似文献
