The authors examined the extent to which performance on interpersonal cognitive problem-solving (ICPS) tasks is affected by whether the goals within the dilemmas to be addressed are sex typed. Fifty children, aged 7-8 years old, were tested for the core ICPS skills of Alternative Solutions Thinking (AST) and Consequential Thinking (CT) on a series of 8 social problem-solving tasks, 4 having goals characteristically more attractive to boys and 4 with goals more attractive to girls. A 2 x 2 MANOVA was used to compare the performances of boys and girls on each set of sex-typed tasks with the 3 dependent variables of liking for the tasks, number of alternative solutions suggested, and the number of consequences anticipated. As expected, liking for the tasks was higher if the activities were characteristically associated with the participant's own gender (p < .001), although the different tasks did not produce any significant gender differences in the numbers of AST or CT suggestions they prompted. Gender differences in children's peer relationships were considered, and the implications of these results for the format of ICPS interventions are noted. 相似文献

The use of rate-building procedures to encourage the production of high response rates and to develop fluency has been increasingly justified by research on precision teaching and automaticity. Rate-building procedures often ensure both speed and accuracy, and claims have been made that such procedures result in greater retention, persistence, and generalization of trained skills, as well as preference by students. Given the potential importance of these claims for behavior analysts and educators alike, this review assesses the validity, generality, and implications of research on rate building. The review revealed sparse empirical evidence that retention, persistence, and generalization of skills result from the use of rate-building procedures when the effects of practice and reinforcement rate are controlled. Given the results of this review, the implications are discussed in the context of behavior-analytic research (e.g., behavioral momentum), and further research is recommended. 相似文献

Groups that target aggression on the inpatient milieu usually use psycho-educational and cognitive-behavioral techniques. In contrast, this article presents an experiential approach that targets the moment-by-moment experience within the inpatient group. It makes unique use of group-closing relaxation exercises that facilitate cohesion, consolidate the affectively charged material generated during the session, and reorganize patients' emotional/cognitive understanding of themselves and the world around them. These groups also give patients the opportunity to negotiate the affective residue associated with past aggressive acts, and the opportunity to examine the personal meaning and underlying assumptions behind ongoing group interactions. We describe several techniques or modes of intervention. The authors also use case examples to illustrate the theory, technique, and impact the approach can have on its members. 相似文献

Visual feature integration theory: past,present, and future 总被引:4,自引:0,他引:4
Quinlan PT 《Psychological bulletin》2003,129(5):643-673
Visual feature integration theory was one of the most influential theories of visual information processing in the last quarter of the 20th century. This article provides an exposition of the theory and a review of the associated data. In the past much emphasis has been placed on how the theory explains performance in various visual search tasks. The relevant literature is discussed and alternative accounts are described. Amendments to the theory are also set out. Many other issues concerning internal processes and representations implicated by the theory are reviewed. The article closes with a synopsis of what has been learned from consideration of the theory, and it is concluded that some of the issues may remain intractable unless appropriate neuroscientific investigations are carried out. 相似文献

Although much social science research has been conducted within American Indian and Alaska Native (AIAN) communities, relatively little research has been conducted by or for those communities. We describe an approach that facilitates the active involvement of AIAN communities in the research process, from conceptualizing the issues to be investigated to developing a research design, and from collecting, analyzing, and interpreting the data to disseminating the results. The Tribal Participatory Research (TPR) approach is consistent with recent developments in psychology that emphasize the inclusion of community members and the social construction of knowledge. We describe the foundations of the approach and present specific mechanisms that can be employed in collaborations between researchers and AIAN communities. We conclude with a discussion of the implications of the use of TPR regarding project timelines and budgets, interpretation of the data, and ultimately the relationships between tribes and researchers. 相似文献

When PD, an alphanumeric-colour synaesthete, is shown black digits or letters, each grapheme elicits a highly specific colour, called a "photism" (e.g., a 2 induces green, a Z induces brown). Previous experiments showed that photisms interfere with video-colour naming when the photism colour and the video colour are incongruent. Here we used coloured ambiguous graphemes that could be interpreted as either digits or letters depending on context (e.g., an ambiguous grapheme was interpreted as a 2 if presented within a block of digit trials, but as a Z if presented within a block of letter trials). Ambiguous graphemes were presented in video colours that were either congruent or incongruent with PD's photisms. Crucially, what was a congruent trial in one context was an incongruent trial in the other context. PD's pattern of response times indicated that identical graphemes could induce differently coloured photisms depending on their interpretation. This suggests that the meaning of graphemes ultimately determines their synaesthetic colour. 相似文献

We evaluated whether synaesthetic colour experiences (i.e., photisms) guide or attract attention. An alphanumeric-colour synaesthete, J, and seven non-synaesthetes searched for target digits presented against backgrounds that were either congruent or incongruent with the colours of J's photisms for the target digits. For J, the slope of the search function for detecting the target digits on incongruent trials was shallower than the slope of the search function for detecting the target digits on congruent trials. In contrast, for the seven non-synaesthetes, the slopes of the search functions for detecting the target digits on congruent and incongruent trials were equivalent. These findings suggest that synaesthetic colour experiences influence the efficiency of visual search by guiding or attracting attention. 相似文献

Most computational and neural-style models of contour completion (ie illusory and occluded contours) are based on interpolation: the filling in of an edge between two visible edges. The results of three experiments suggest an alternative conception, that units are formed as a result of extrapolation from visible edges. In three experiments, subjects reported illusory contours between standard illusory-contour inducing elements and forms that do not, by themselves, induce illusory contours. We suggest that these forms are not a special case of inducing elements but that they represent a different class--receiving elements. Receiving elements are forms that can receive an illusory contour but cannot generate one, and they can alter contour formation. In experiment 1, receiving elements increased the judged clarity of illusory contours. In experiment 2, illusory edges were seen to connect to corners, line ends, and even the edges of circles. Boundary formation in motion displays also appears to be based on extrapolation. In experiment 3, subjects reported that small moving dots altered the formation of spatiotemporally defined boundaries. Implications for higher-order operator and network models of boundary formation are discussed. 相似文献

Inhibition and working memory: effect of acute sleep deprivation on a random letter generation task]
Patricia Sagaspe André Charles Jacques Taillard Bernard Bioulac Pierre Philip 《Revue canadienne de psychologie expérimentale》2003,57(4):265-273
The literature contains inconsistent data on the effects of acute sleep deprivation on the superior cognitive functions. The primary purpose of this study is to determine the effectiveness of inhibition, one of the functions of the working memory executive centre (EC), over an extended, 36-hour waking period. Inhibition is a cognitive mechanism whereby individuals ignore non-relevant information recorded in their working memory. We also tested the effects of a 36-hour period of acute sleep deprivation on simple reaction time. Twelve young, healthy volunteers (M = 21.5 years, sigma = 2.3) performed a random generation task involving letters and a simple reaction time psychomotor test over four sessions held at 10-hour intervals. Each participant was assigned a "constant routine." Participants were kept awake in a prone position within a room whose environment was held strictly constant (light, noise, temperature, meals, etc.). This control procedure provided assurance that any variation in participant performance was solely caused by sleep deprivation. The random generation task, nearly two minutes in length, consisted in verbally producing a sequence of 100 letters in a random fashion (i.e. by inhibiting, for example, alphabetical order) and by keeping to a set rhythm. Our assumption was that capacity for inhibition diminished as the number of hours of sleep deprivation increased. The simple reaction test, 10 minutes in length, involved pressing a button as swiftly as possible to cause a black square to disappear from a screen. In this case our assumption was that acute sleep deprivation alters simple reaction time. Analysis of variance (ANOVA) through repeated measures using the "sessions" factor as an intra-subject variable showed no significant changes in randomization indices of the random generation task, contrary to analysis of average simple reaction times. Participants' reaction times deteriorated over the first two minutes of the test during the night they were deprived of sleep. It would seem that the contradictory results of previous studies of the effects of acute sleep deprivation on the inhibition function would be due to errors in factor identification. In conclusion, the inhibition function, as measured during the performance of a brief task, seems to remain intact during an extended, 36-hour waking period. Simple reaction time assessed by means of a brief psychomotor test is affected during a night of sleep deprivation. The working-memory inhibition executive function shows greater resistance to acute sleep deprivation than does psychomotor reaction time for the performance of short tasks. 相似文献

Nancey Murphy is a key second-generation figure in the field of religion and science. Through a variety of responsibilities, some of which are reviewed here, she has worked as a discipline builder over the last fifteen years. After trying to convey the general spirit of Murphy's work, the author focuses on five areas where readers might resist her conclusions, including her "postmodern" theory of scientific (and religious) knowledge and truth, her treatment of theology and science as "separate but equal," and her defense of physicalism. 相似文献
