Performance in a recognition task involving two amplitudes of the same tone was investigaled over a wide range of presentation schedules. The task was arranged so that there was no trial-to-trial feedback or other information regarding the relative frequencies of the two tones. The hit and false alarm rates (the proportion of “loud” responses to loud and soft stimuli, respectively) on any given trial were strongly influenced by the stimulus and response on the preceding trial. In general, Ss tended to repeat the last response and were more accurate after a stimulus alternation than after a stimulus repetition. In addition, hit and false alarm rates were inversely related to the presentation probability of the loud tone, in contrast to the direct relation typically found in signal detection experiments and in recognition experiments with trial-to-trial feedback. A mathematical model incorporating three processes (memory, comparison, and decision) was shown to give a good account of these data. 相似文献

Two experiments investigated the effects on auditory signal detection of introducing visual cues that were partially correlated with the signal events. The results were analyzed in terms of a detection model that assumes that such cue-signal correlations will not affect sensitivity, but will instead cause the subject to develop separate response biases for each cue. The model specifies a functional relationship between the asymptotic values of these cuecontingent biases. The overall results of the experiments supported the detection assumptions of the model and the general bias learning assumption, but indicated a more complex learning process than that specified by the model. 相似文献

A modification of stimulus sampling theory is presented. The restriction that each stimulus element is conditioned to one and only one response is replaced with the notion of a scale of conditioning for each element. This variation provides a context in which such variables as reward magnitude and motivation can be viewed as determiners of behavior. Some experimental results on multiple response problems also have a natural interpretation in terms of these ideas. 相似文献

Cross-cultural commonality and variation in folk theories of knowing were studied by examining the organization of verbs of knowing in German and Japanese adults. German and Japanese adults performed one of two tasks: a similarity judgment task and an attribute rating task. Organizational structure was assessed for the similarity judgment task using multidimensional scaling and additive similarity tree analyses. The attribute rating task was used to describe the characteristics that organized the dimensions and clusters emerging from the scaling solutions. The folk theory of mind displayed was an information processing model with constructive components, although the constructive aspects were more salient for the Germans than for the Japanese. 相似文献

A population-based randomized intervention trial for the prevention of conduct problems (i.e., oppositional defiant disorder and conduct disorder) is described. The LIFT (Linking the Interests of Families and Teachers) intervention was designed for all first- and fifth-grade elementary school boys and girls and their families living in at-risk neighborhoods characterized by high rates of juvenile delinquency. The 10-week intervention strategy was carefully targeted at proximal and malleable antecedents in three social domains that were identified by a developmental model of conduct problems. From 12 elementary schools, 671 first and fifth graders and their families participated either in the theory-based universal preventive intervention or in a control condition. The intervention consisted of parent training, a classroom-based social skills program, a playground behavioral program, and systematic communication between teachers and parents. A multiple measure assessment strategy was used to evaluate participant satisfaction and participation, fidelity of implementation, and the immediate impacts of the program on targeted antecedents. 相似文献

We describe a set of algorithms that enhance the sensitivity of cancellation tests used in assessing visuospatial neglect. The algorithms can be readily implemented on a computer and can provide temporal and nontemporal data on strategies used during cancellation. We also present preliminary results from a group of 68 right-hemisphere brain-damaged patients and 12 age-matched control participants, which demonstrate the clinical significance of the measures we have defined. 相似文献

In this article, the authors describe the existential situation of the fast-track suburban couple and a treatment approach
based upon the philosophical concepts of Gabriel Marcel and Viktor Frankl. In this treatment approach, the therapist uses
availability, primary reflection and secondary reflection treatment experiences to host the client couple's discovery and
actualization of the meaning potential in their intimate life. 相似文献

The present study investigated the role of social support provisions and efficacy cognitions in adherence to a prescribed exercise regimen. A generalized estimating equations approach was employed to estimate regression coefficients via an iterative weighted least squares algorithm. Findings indicated that when employed as time-varying covariates, the social provisions of reassurance of worth, attachment, and, to a lesser extent, guidance were significantly associated with intraindividual fluctuations in program adherence. Specifically, individuals with a greater sense of self-worth were more likely to adhere throughout the program, whereas the effects of subject's perceptions of greater attachment, although generally related to sustained adherence, fluctuated over time. Findings also suggest that individuals perceiving higher levels of guidance were less likely to adhere during the early and concluding stages of the exercise program. Although synchronous covariation existed between efficacy cognitions and attendance, self-efficacy was not predictive of intraindividual change in attendance over time. Results are discussed in regard to the importance of self-referent processes and social provisions in exercise adherence, and the utility of the proposed generalized estimating equations approach to the analysis of longitudinal data. 相似文献
