The Monty Hall dilemma (MHD) is a notorious probability problem with a counterintuitive solution. There is a strong tendency to stay with the initial choice, despite the fact that switching doubles the probability of winning. The current randomised experiment investigates whether feedback in a series of trials improves behavioural performance on the MHD and increases the level of understanding of the problem. Feedback was either conditional or non-conditional, and was given either in frequency format or in percentage format. Results show that people learn to switch most when receiving conditional feedback in frequency format. However, problem understanding does not improve as a consequence of receiving feedback. Our study confirms the dissociation between behavioural performance on the MHD, on one hand, and actual understanding of the MHD, on the other. We discuss how this dissociation can be understood.  相似文献

Abstract

Vertigo and dizziness may cause considerable discomfort and feelings of uncertainty. It is no surprise that vertigo is the most disabling symptom in Menière's disease, an inner ear disorder. The other two cardinal symptoms are tinnitus and hearing impairment. In this study, one severely disabled woman was treated with a cognitive-behavioural treatment comprising, among other components, relaxation training, stabilization of gaze, cognitive restructuring and behavioural task setting. The patient responded well to the treatment, during which her vertigo attacks disappeared. During the follow-up period, she experienced vertigo attacks again, but after two booster sessions the vertigo attacks vanished for the rest of the follow-up period. The results are further discussed.  相似文献

Job satisfaction data on managerial personnel were used to illustrate how organizations can be differentiated and described as reinforcer systems. Twenty-seven specific satisfaction scales were regressed on overall job satisfaction, separately for each of five groups of managers from five organizations. For all groups, overall satisfaction was found to be determined mainly by scales concerning challenge of the job and prospects of one's chosen career. Application of decremental stepwise multiple regression procedures to obtain minimum-variable-set equations resulted in different, though overlapping, sets of variables in the equations for the different organizations. These results suggest a way of describing organizations as reinforcer systems, in terms of the specific determinants of overall satisfaction for the organization.  相似文献

Earlier research based on 81 Occupational Reinforcer Patterns (ORPs) suggested a nine-category classification of occupations. The present research, based on 148 ORPs, investigated the ability of that classificatory system to assimilate new information. Cluster analysis of the 148 ORPs yielded an eight-category classification of occupations in which five of the original occupational clusters appeared virtually unchanged; the other four original clusters were combined into two occupational clusters. One new cluster was identified. Principal factors analysis was employed to study the factor structure of the occupational reinforcers and to highlight the essential nature of the classificatory system. Five reinforcer factors were identified.  相似文献

The Minnesota Job Requirements Questionnaire (MJRQ) was developed and administered to supervisors of 11 selected jobs who rated the ability requirements of the job they supervised. The MJRQ represented each of nine GATB aptitudes by five items in a Likert-type format. MJRQ ratings were compared with expert ratings in the Dictionary of Occupational Titles (DOT) and Occupational Ability Patterns (OAPs) derived from administration of the General Aptitude Test Battery (GATB). Reliability of MJRQ ratings was shown by high Hoyt reliability coefficients. Comparison of mean ratings and variabilities of ratings by supervisors in a job showed construct validity for the MJRQ approach, as did intercorrelations of MJRQ ratings. OAPs derived from the MJRQ compared favorably with those derived from the GATB and DOT, showing promise for the parsimonious MJRQ approach to the development of OAPs.  相似文献

Sixty-nine second grade suburban children were rated by three teachers using a classroom behavior inventory. Factor analysis was performed to test the a priori structure of the instrument. The 18-item inventory was analyzed on three factors: Task-Oriented vs Distractibility, Extroversion vs Introversion, and Considerateness vs Hostility. The three factors loaded perfectly according to the a priori design. The need for further investigations concerning the reliability and a comparison of the rating scale with objective observations is indicated.  相似文献

RESUMEN

La Psicología Cognitiva es una de las áreas más pujantes de la Psicología actual. Pese a lo fructífero de esta nueva rama de la Psicología, es necesario formular algunas críticas a este enfoque. Este será el tema principal del presente artículo. Las críticas estarán centradas en las llamadas “analogías formales”. Cuando un dominio de fenómenos es difícil y confuso para nuestra compresión, una solución lícita es establecer algún tipo de analogía entre ese dominio y otro dominio que conocemos mejor. Lo que hemos denominado analogías formales sirven de elementos de vertebración teórica de los datos psicológicos pero, por otra parte, mue stran debilidades importantes. Las principales analogías de la Psicología Cognitiva serán analizadas en este artículo mostrando sus debilidades más importantes.  相似文献

Thanks to the publication of the two decrees of 12 April 2018, and six years after the promulgation of the Jardé law, the scope of the law of 5 March 2012 as well as the different categories of research involving the human person finally appear clearly. Beside interventional research that includes intervention on the person that is not justified by usual care, the contours of two categories of research have been precised: interventional research with minimal risk and minimal burden and “non-interventional” research, whose name is questionable. If the latest decrees have managed to reach a more coherent set of rules, the French legal and regulatory provisions remain complex and incomplete. Complex, in view of the multiplicity of statutory texts adopted since the promulgation of the Jardé law. Incomplete, because the needs for ethical evaluation provided for by the international ethical principles of research are not systematically covered by French law.  相似文献
