This essay provides guidelines for designing a doctoral program in behavior analysis. First, we propose a general accomplishment for all behavior analytic doctoral students: that they be able to solve problems concerning individual behavior within a range of environments. Second, in order to achieve this goal, we propose that students be trained in conceptual and experimental analysis of behavior, the application of behavioral principles and the administration of behavioral programs. This training should include class work, but it should emphasize the immersion of students in a variety of environments in which they are required to use behavior analytic strategies. Third, we provide an example of a hypothetical graduate program that involves the proposed training. Finally, an evaluation plan is suggested for determining whether a training program is in fact producing students who are generalized problem-solvers. At each step, we justify our point of view from a perspective that combines principles from behavior analysis and educational systems design. 相似文献

M P Kowitt 《Journal of personality assessment》1985,49(1):21-25
In traumatized patients, Rorschach responses draw from a variety of sources, including the traumatic event itself, past and current experiences, and internal fantasy. As complex and highly condensed mental constructions, these responses often serve to reveal the meaning of the trauma in terms of the patient's prevailing personality conflicts. In many cases, this meaning may be hidden in the response's distortion of or elaboration on images drawn from the actual event. 相似文献

Updating Norman's "Adequate Taxonomy": intelligence and personality dimensions in natural language and in questionnaires 总被引:1,自引:0,他引:1
Research on the dimensions of personality represented in the English language has repeatedly led to the identification of five factors (Norman, 1963). An alternative classification of personality traits, based on analyses of standardized questionnaires, is provided by the NEO (Neuroticism, Extraversion, Openness) model (Costa & McCrae, 1980b). In this study we examined the correspondence between these two systems in order to evaluate their comprehensiveness as models of personality. A sample of 498 men and women, participants in a longitudinal study of aging, completed an instrument containing 80 adjective pairs, which included 40 pairs proposed by Goldberg to measure the five dimensions. Neuroticism and extraversion factors from these items showed substantial correlations with corresponding NEO Inventory scales; however, analyses that included psychometric measures of intelligence suggested that the fifth factor in the Norman structure should be reconceptualized as openness to experience. Convergent correlations above .50 with spouse ratings on the NEO Inventory that were made three years earlier confirmed these relations across time, instrument, and source of data. We discuss the relations among culture, conscientiousness, openness, and intelligence, and we conclude that mental ability is a separate factor, though related to openness to experience. 相似文献

According to the physiological animal model proposed by Gorenstein and Newman (1980; see also Newman, Gorenstein, & Kelsey, 1983), psychopaths and extraverts may be characterized by a common psychological diathesis related to behavioral inhibition (see also Fowles, 1980; Gray, 1982). One aspect of this diathesis involves deficient passive avoidance learning, which has been central to explanations of "unsocialized" (e.g., Trasler, 1978) and antisocial behavior (e.g., Hare, 1970). Results from three experiments supported our prediction that psychopaths and extraverts would exhibit deficient passive avoidance relative to nonpsychopaths and introverts, respectively. In addition, the passive avoidance deficit was particularly evident in tasks that required subjects to inhibit a rewarded response in order to avoid punishment. The latter finding may be important for explaining the inconsistent results regarding passive avoidance learning in psychopaths (e.g., Chesno & Kilmann, 1975; Schmauk, 1970). Discussion of the results focuses on the importance of reward in mediating the passive avoidance deficit of "disinhibited" individuals and on the existence of an indirect relationship between psychopathy and extraversion: one that is consistent with the observed experimental parallels as well as with the more ambiguous evidence regarding a direct correlation between measures of the two syndromes. 相似文献

Extended the literature on age differences on the Hand Test using a multivariate model to examine absolute and relative differences in response. Participants were 47 adults (M age = 22.47 yrs.), 24 males and 23 females; and 45 older adults (M age = 64.87 yrs.), 21 males and 24 females. Data were analyzed in terms of percentage of response and absolute frequency of specific responses, between the age groups. Results indicated similar findings to those previously reported for the Hand Test, though magnitude of personality deterioration or withdrawal was lessened, for the percentage analysis. Results indicated the importance of using both absolute frequency of response and percentage of response in the interpretation of projective test data, especially for older adults. 相似文献
