Summary We investigated the hypothesis that the detection of a scene segmentation is facilitated when coincident with a segmentation in another visual dimension. We measured the percentage of the correct detection of horizontal or vertical tritanopic color segmentations perpendicular to, or coincident with, segmentations produced by a subjective-contour stimulus. We found that color discrimination improves when the color segmentation is coincident with the segmentation formed by the subjective contour.In a second experiment, using a yes-no procedure, we found that sensitivity for the detection of luminance segmentations coincident with subjective-contour segmentations increased. However, the detectability of luminance segmentations coincident with a line deteriorated (the gap effect). We conclude that the notion of facilitated detection of coincident segmentations has several problems that undermine its intuitive appeal. 相似文献

This study examines how gender is related to self-evaluations of information to discuss current social and political issues. The sample is one of predominantly white (96%) college graduates. Using alumni samples, we look at how members of four classes that span 20 years evaluate their knowledge to hold conversations on a variety of public affairs issues ranging from the Strategic Defense Initiative to government funding of abortion. We find gender differences, with men perceiving themselves more knowledgeable in conversations and women less so. We raise the possibility that they are “doing gender.” The implications of these findings are explored. 相似文献

An experiment was conducted to determine how visual attention is allocated in response to pairwise combinations of location, color, and size cues. Subjects viewed displays of eight letters arranged into an 'X' pattern emanating from a central fixation point. The letters varied on the dimensions of location (foveal or parafoveal positions), size (large or small), and color (red or blue). Seven of the letters were 'X's and the remaining, critical letter was either an 'R' or an 'L'. Subjects were given advance cues about characteristics of the critical letter on two of the three dimensions (location size, and color). The cues varied in their validity such that on any trial either both dimensions were validly cued, one dimension was validly cued while the other was invalidly cued, or both cues were invalid. Subjects were instructed to try to use the cues to find the critical letter, and response times to identify it as an 'R' or an 'L' served as the main dependent measure. Two models were evaluated against the data; in one, location cues are viewed as having distinct effects on an early stage of attention whereas color and size cues operate only in a later, selection stage. In the other model, all cues are used in a similar way to select display items for serial, focal attention. In general, the serial processing model provides a more complete account of the data. 相似文献

A series of experiments on intersensory facilitation demonstrates that non-informative sound of low to moderate intensity (30/80 dB) facilitates the reaction to a visual stimulus. By manipulating the preprocessing and perceptual stages of the visual signals, it appears that auditory intensity reduces choice reaction time independently from the positive influence of the intensity and duration of the visual imperative signal, but interacts with the effect of stimulus degradation. Degraded stimuli take more profit of the sound than intact stimuli. Besides a short-term activation effect, originated by accessories of the auditory modality, on the motor adjustment stage (cf. Sanders 1983), the results suggest that the accessory influences the stage of feature extraction. 相似文献

The parenting attitudes of adolescent and older mothers were assessed at 1 and 12 months postpartum to explore group differences and determine if these attitudes predicted quality of home environment and parenting behaviors at 12 months. Adolescent mothers scored significantly lower than did older mothers in empathy toward children's needs, but there were no significant group differences on three other parenting attitude constructs. There were no significant correlations between parenting attitudes at 1 month and parenting behaviors at 12 months for either group. For adolescent mothers at 12 months postpartum, the only attitude construct that was significantly related to concurrent quality of parenting was developmental expectations of the child. These and other findings are discussed in the context of current theory and intervention related to adolescent parenting. 相似文献

The application of various types of techniques for structuring the interchange and feedback process in adolescent psychotherapy groups is described. Techniques include random assignment of "roles" for each member during sessions, "parent hot seat" exercises, group goal booklets, and negotiation exercises. These have proved helpful in ensuring effective group participation, providing practice in social skills and verbalization of feelings, and in the development of other specific mastery skills. 相似文献

This study compared the REST (Real Economy System for Teens) program with traditional talk therapy in the treatment of oppositional defiant adolescents. The REST program uses rules for five target behaviors: room care, personal hygiene, completion of chores, abusiveness, and safety violations. Objective measures and subjective parental ratings were taken. Twenty-five adolescents were assigned to each therapy group. In the REST program the adolescent was provided with only food and shelter. The adolescent had to earn money through the REST allowance program to pay for everything else. Earning the allowance was made contingent upon compliance with all rules for the five target behaviors. The results showed significantly greater improvement on all target behaviors for the REST program than for traditional therapy. In addition, parents of adolescents in the REST group reported that their adolescents seemed happier, more relaxed, and closer to them. 相似文献

The size of the perceptual unit used in reading was addressed using the predesignated target paradigm. Sixteen subjects viewed the following stimuli in random order: the words tee, the, tie, and toe; the nonwords eet, eht, eit, and eot; and the letters e, h, i, and o. Subjects fixated on the location of the center letter and identified the letter as e, h, i, or o, alternatives which were known to them at the onset. A word superiority effect was obtained for the common word the but not for the less common words tee, tie, and toe. The word superiority effect was attributable to bias rather than discriminability: Subjects exhibited a bias to perceive the words in this experiment as the (i.e., there was a bias to perceive h in the t e stimulus presentations). These results suggest that the common word the is processed in reading units that are larger than the letter, and that the system is biased to perceive common rather than uncommon words in data-limited conditions. 相似文献

An adolescent patient's action during analysis reflects both neurotic conflicts and the developmentally determined task of establishing an integrated self-representation. Concern for the consequences of the action often provokes the analyst to respond, covertly, with interventions intended to change the action through influence rather than understanding. This can lead to a distortion of the analytic process which, in itself, may be an enactment of the developmental conflict. Examination of such interventions reveals a lack of analytic neutrality and an unconscious participation in the patient's neurotic and developmental conflicts. Clinical material from the analyses of two fourteen-year-old girls and a sixteen-year-old boy is presented to illustrate and support this hypothesis. 相似文献
