Recent research on social cognition suggests that lifelike visual and vocal information about a person may strongly mediate the impact of prior social categorical knowledge on social judgements. Other research, however, on the contribution of visual cues to impression formation, suggests that they have relatively little impact. This study sought to resolve these conflicting findings by examining the effect of visual cues on social judgements when subjects possess prior social categorical knowledge varying in salience to the experimental task. Videotaped target interviews were monitored by observers in either sound and vision or sound only, and measures were taken of the targets' perceived personality, their ‘actual’ and ‘predicted’ social performance, and social acceptance by observers. Whilst salience of categorization strongly influenced the quality of judgements, visual cues had little if any effect. However, visual cues strongly influenced subjects' confidence in all three sets of judgements, sound and vision subjects being consistently more confident than their sound only counterparts. The findings are discussed in relation to previous research in both social cognition and visual cues. 相似文献

In an attempt to investigate the range effect obtained by Moyer and Bayer (1976), two groups of subjects were taught to associate colors with circles that differed in size by larger or smaller intervals and then participated in a symbolic comparison task, in which they determined which of two simultaneously presented symbols (the first letters of two colors) represented the larger magnitude. A third group of subjects, who merely learned an arbitrary ordering of the colors along the dimension of size, also participated in the symbolic comparison task. Despite the fact that no practice trials were given, there was no effect of interval size in either early or late blocks, and the circle-learning groups did not differ in performance from the group who only learned an arbitrary ordering of colors, even when pairs containing end terms were removed from the analysis. It is concluded that subjects do not use analogue codes in symbolic comparison tasks involving small, repeated sets of arbitrarily defined symbols. 相似文献

Parents' teaching strategies with their children: The effects of parental and child status variables
Anthony D. Pellegrini Gene H. Brody Irving E. Sigel 《Journal of psycholinguistic research》1985,14(6):509-521
The intent of the study was to examine the effects of parental (mother and father) and child (gender and communicative status) status variables on the teaching strategies used by parents in a paper-folding task. The linguistic and nonverbal strategies of 120 parent-child groupings were analyzed during paper-folding tasks. Parents' strategies were coded according cognitive demand and directiveness. Results indicated that strategies varied as a function of children's communicative status. Parents were less directive and more demanding of nonhandicapped children compared to handicapped children. Parents' strategies seemed to be determined by children's ability to sustain discourse. Results are discussed in terms of Vygotsky's notion of the zone of proximal development.This research was partially supported by a grant from the U.S. Office of Education, Office of Special Education (Grant No. G007902000) to I.

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed. 相似文献

In two experiments, subjects read passages of text and circled instances of a target letter under normal conditions or while engaged in articulatory suppression. In Experiment 1, subjects searching for the letter e made a disproportionately large number of errors on the word “the” and more errors when e occurred in unstressed than in stressed syllables of three-syllable words. In Experiment 2, subjects searching for the letter f made an exceedingly large number of errors on the word “of.” Articulatory suppression significantly reduced the stress effect in the three-syllable words but did not reduce the tendency to make errors on “the” or “of,” suggesting that phonological recoding is responsible for this effect of stress but does not influence the unitization processes of reading. 相似文献

Since both speech and color have perceptual ramifications in language, the present study was developed to study speech perception through color perception. With the recent advances in perception generally and color perception specifically, this nontraditional approach to studying speech perception appeared reasonable. The 12 consonants utilized in this study generated 144 pairs of nonsense CV-syllables. The consonant ensemble was selected because it accommodated a maximum number of phonological features with a minimum number of phonemes. The 46 subjects, who were in junior high school with an age range of 11 through 14 years, responded to each of the stimulus pairs by assigning (associating) to it one of the six primary colors. Because of the perceptual orderliness associated with subjects' judgments, the results indicated that color can be used to study speech perception. Specific findings included the retrieval of sameness, fronting (or place), and voicing.This study is based on a master's thesis presented to the Graduate School, Tennessee State University in Nashville.

In Experiment 1, 128 experimentally naive, water-deprived rats (Rattus norvegicus) received pretraining access to either 0.25 or 1.5% saccharin, distilled water, or 2.0% saline, followed either by a pairing of 0.25 or 1.5% saccharin with an intraperitoneal injection of 0.15 M lithium chloride (LiCl) or by a pairing of distilled water with LiCl. Preexposure to either saccharin concentration reliably reduced conditioned aversion effects to 0.25% saccharin, relative to that for preexposure to distilled water or saline. But only preexposure to 1.5% saccharin reduced aversion effects to that concentration. In Experiment 2, 48 naive, water-deprived rats received preexposure procedures as in Experiment 1. Afterwards, the rats were tested for neophobia to 0.25 or 1.5% saccharin. Neophobia was reliably greater to the 1.5% concentration. However, preexposure to either saccharin concentration obliterated evidence for neophobia to saccharin, relative to that following preexposure to distilled water or saline. 相似文献
