Testing two cognitive theories of insight 总被引:6,自引:0,他引:6
Jones G 《Journal of experimental psychology. Learning, memory, and cognition》2003,29(5):1017-1027
Insight in problem solving occurs when the problem solver fails to see how to solve a problem and then--"aha!"--there is a sudden realization how to solve it. Two contemporary theories have been proposed to explain insight. The representational change theory (e.g., G. Knoblich, S. Ohlsson, & G. E. Rainey, 2001) proposes that insight occurs through relaxing self-imposed constraints on a problem and by decomposing chunked items in the problem. The progress monitoring theory (e.g., J. N. MacGregor, T. C. Ormerod, & E. P. Chronicle, 2001) proposes that insight is only sought once it becomes apparent that the distance to the goal is unachievable in the moves remaining. These 2 theories are tested in an unlimited move problem, to which neither theory has previously been applied. The results lend support to both, but experimental manipulations to the problem suggest that the representational change theory is the better indicator of performance. The findings suggest that testable opposing predictions can be made to examine theories of insight and that the use of eye movement data is a fruitful method of both examining insight and testing theories of insight. 相似文献

In this paper we describe dissociations of implicit versus explicit access to semantic information in a patient with deep dyslexia. This acquired reading disorder is characterized by the production of morphological (e.g., SLEEP read as SLEEPING) and semantic errors (e.g., HEART read as BLOOD) and consequently provides a potential window into the operation of both aspects of the language system. The deep dyslexic patient in this study (JO) demonstrated implicit semantic access to items in a number of tasks despite the fact that she was unable to correctly read these items aloud. The findings from this study are consistent with a model of lexical deficits that distinguishes between explicit and implicit access to lexical representations on the basis of inhibitory processes. 相似文献

Visual space can be distinguished from physical space. The first is found in visual experience, while the second is defined independently of perception. Theorists have wondered about the relation between the two. Some investigators have concluded that visual space is non-Euclidean, and that it does not have a single metric structure. Here it is argued (1) that visual space exhibits contraction in all three dimensions with increasing distance from the observer, (2) that experienced features of this contraction (including the apparent convergence of lines in visual experience that are produced from physically parallel stimuli in ordinary viewing conditions) are not the same as would be the experience of a perspective projection onto a frontoparallel plane, and (3) that such contraction is consistent with size constancy. These properties of visual space are different from those that would be predicted if spatial perception resulted from the successful solution of the inverse problem. They are consistent with the notion that optical constraints have been internalized. More generally, they are also consistent with the notion that visual spatial structures bear a resemblance relation to physical spatial structures. This notion supports a type of representational relation that is distinct from mere causal correspondence. The reticence of some philosophers and psychologists to discuss the structure of phenomenal space is diagnosed in terms of the simple materialism and the functionalism of the 1970s and 1980s. 相似文献

We conducted several manipulations of mechanical restraint properties during the course of treatment for two profoundly retarded adolescents who exhibited both self-restraint and self-injurious behavior. In study 1, a combination of prompting, differential reinforcement, and stimulus fading reduced one subject's self-restraint, which consisted of holding rigid tubes on his arms. Subsequently, stimulus control of both self-restraint and self-injurious behavior was transferred to tennis wrist bands. In study 2, a second subject's self-restraint—placing his hands in his pants—was immediately eliminated by the use of air splints. Additionally, differential reinforcement and air-pressure fading resulted in the complete mobility of his arms and a substantial increase in appropriate behaviors. Results of this investigation suggest that stimulus fading and transfer may be valuable components in the elimination of self-restraint. 相似文献

PERCEIVING THE MALE VERSUS THE FEMALE FACE 总被引:1,自引:0,他引:1
This study of the perceptual processes in rating the good-lookingness of male compared to female faces finds that more refined distinctions and discriminations, more extreme positive and negative ratings, and more consensus occur for female than for male faces. Facial expression (e.g., smiling) affects the rating of female more than male faces, The results uniformly support the view that facial appearance is a more heavily weighted element in the response to women than to men. 相似文献

This study examined the differential effects of frustration on normal children and those diagnosed as having Attention Deficit Disorder with Hyperactivity. Each group consisted of 16 boys between the ages of 6 and 8 years who were prematched for age, grade, and classroom placement. All children completed a series of arithmetic problems in order to earn toy rewards. Using a variant of Mischel's (1974) delay-of-gratification paradigm, children were presented with two choice-of-delay conditions in a randomly assigned, counterbalanced sequence: a free-choice conflict situation involving a long-passive or short-active reward delay, and a short-active delay. Results showed that a significantly greater proportion of hyperactive children chose to complete problems for an immediate reward compared to their normal control counterparts (p less than .01). Group differences were no longer apparent in the short-active delay trial. The results are discussed in terms of frustration tolerance and contributing factors such as cognitive-attentional style. Implications for treatment and future directions are delineated. 相似文献

Suggesting that the hospital can be understood as a metaphor for human existence, a pastoral method is developed as response to the issues of chaos, contingency, powerlessness, finitude, and vulnerability. Clinical examples are cited and evaluated from the perspectives of pastoral and biblical theology. 相似文献

Summary Three experiments were conducted to examine the effect of temporospatial discontinuity on route learning. Discontinuity was created by showing subjects in a route-learning task a set of environmental scenes comprising a route in scrambled, rather than logically sequenced, order. Results from Experiments 1 and 2 indicated that discontinuity during learning affected the accuracy and the quantity of the route knowledge acquired, but suggested that the processes underlying acquisition were relatively robust. Results from Experiment 3 suggested that learning routes under conditions of discontinuity leads to a greater exaggeration of distance between route segments than is the case without discontinuity. 相似文献

Prolonged seclusions can result in exacerbation of psychotic symptomatology, self-injurious behavior, and increased likelihood of subsequent aggression. A patient's aggression can be contextualized as an interpersonal and cyclic series of events in which both the staff and the patient can play a contributing role. If this cycle can be interrupted, the likelihood of aggression decreases. The authors describe this aggression cycle and some strategies for interrupting it via a “decompression” treatment modality. Four case examples illustrate the range of outcomes achieved with patients who had been secluded for between 2 to 5 years due to their chronic history of aggression. The authors offer suggestions for developing a decompression treatment program. 相似文献

Relations between psychological adjustment and physical attractiveness were examined longitudinally in substance abuse inpatients, controlling for the effects of length of drug abuse, length of inpatient stay, age, and socioeconomic status. Measures of adjustment and attractiveness were obtained during the first week of admission and six weeks later (within two weeks of discharge). Regression analyses indicated that initial attractiveness did not predict later adjustment, and initial adjustment did not predict later attractiveness. Partial correlation analyses revealed a positive association between attractiveness and adjustment at the first time point, but not at the later time point. These results suggest that physical attractiveness exerts only a temporary effect on judgments of adjustment in an inpatient setting. Attractiveness may affect decisions made when screening patients at mental health facilities, but may not affect decisions made over the full course of inpatient treatment. 相似文献
