In the block design task, one type of intelligence test task, the subject reproduces a square-field pattern by assembling cubes having solid and diagonally divided surfaces. The task requires that the subject recode the perceived stimulus pattern into the alternatives available on the block surface. This experiment examined the effect on response or reproduction time of perceptual cohesiveness of pattern, quantified as the number of adjacent same-colored edges of cubes which abutt to form the pattern. This stimulus variable interacts with the type of design (quantified as total set size for designs constructed of all solid surfaces, all diagonally divided surfaces, or mixtures of the two types of surfaces) and with cuing (presence or absence on stimulus pattern of a superimposed grid congruent with block edges of the constructed design). Cohesiveness increases the difficulty of “mentally slicing” or recoding the pattern into the set of block alternatives. The psychological processes involved in recoding probably are the most important ones underlying the intelligence test task. 相似文献

The paper shows that for any invalid polysyllogism there is a procedure for constructing a model with a domain with exactly three members and an interpretation that assigns non-empty, non-universal subsets of the domain to terms such that the model invalidates the polysyllogism.I am grateful to T. J. Smiley and an anonymous referee for comments that improved this paper. 相似文献

Eighty subjects participated in a study with five age groups (20, 30, 40, 50, and 60 years). Forty subjects showed evidence of factors related to brain dysfunction (risk factors). Their performance on a Sternberg-type memory scanning task was assessed. Age-related slowing of virtually all aspects of the memory scanning process was observed in the healthy group. However, the effect of the presence of risk factors was larger than that of biological age. The results of the present study make a reasonable case for the view that many age effects reported in the literature can be largely explained by suboptimal brain functioning, i.e., by other factors than aging per se. 相似文献

Group therapy with inner city Hispanic acting-out adolescent males is described as an effective psychotherapeutic modality in treating this difficult population. Topics addressed include the development of personality during adolescence, Hispanic family dynamics and gender roles, group therapy as a pseudofamily structure, stages of group development as they pertain to this population, and the group therapist's role and characteristics in the treatment situation. 相似文献

The behavioral correlates of human judgment have received little attention from judgment and decision making researchers. One behavioral domain that provides for the study of judgment-behavior relations is task motivation (i.e., the allocation of time and effort to a task). Judgments of contingent relations are primary components of several theories of motivation, including expectancy theories and the theory of behavior in organizations proposed by Naylor, Pritchard, and Ilgen (1980). The characteristics of heuristic judgment processes are hypothesized to affect contingency judgments and thus behavioral allocations of time and effort. This paper examines the effects of the anchoring and adjustment heuristic upon (a) judgments of future effort and performance and (b) upon actual allocations of time and effort using several types of anchoring information. Results indicate that both irrelevant and relevant information have strong anchoring effects on effort and performance judgments, but do not have concomitant effects on behavior. Implications for the role of judgment in motivation and for the link between judgment and behavior are discussed. 相似文献

Disruptive behavior disorders in children and adolescents can lead to a lifetime of problems. The 2 disruptive behavior disorders identified in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM‐IV; American Psychiatric Association, 1994) are oppositional defiant disorder and conduct disorder. Although much research has been conducted to learn more about these 2 disorders, little is known about gender differences in the disorders. There is a dearth of specific information regarding girls with disruptive behavior disorders. This article discusses the diagnosis, risk factors, and treatment of oppositional defiant disorder and conduct disorder while incorporating information specific to girls to investigate how disruptive behavior disorders differ for girls. 相似文献

The role of the otoliths in the perception of verticality is analyzed in two different gravitational environments, 1 g and 1.5 g , and in different roll body positions between upright and upside down. The subjective visual vertical (SVV) is determined when a subject judges the orientation of an indicator as apparently vertical. An increase of g level hardly affects the SVV in the subject's frontal plane (y-z plane). However, for the first time, a three-dimensionally adjustable indicator was used for the SVV and this revealed a new phenomenon: An increase of g level induces a backward slant of the SVV into subject's median plane (x-z plane). The data are discussed with regard to Mittelstaedt's SVV theory; particular emphasis is given to the otolith-head coordinate transformation and the normalization of afferent otolith components. The results of this study provide evidence that the former is implemented at an earlier level and thus precedes the latter. 相似文献

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration. 相似文献
