The interrelatedness of attitudes toward homosexuals, Blacks, women, and old people was studied, as well as attitude differences on demographic variables. Three hundred and nine White undergraduates responded to the Homosexual Attitude Scale, The Attitudes Toward Women Scale, Multifactor Racial Attitude Inventory, and two attitudes toward old people scales. Nine of the ten possible intercorrelations were significant beyond the .01 levels. Prejudice toward quite distinct outgroups appears to be a generalized attitude. Attitude differences were found on the demographic variables of sex, political party, and religion. Women expressed more tolerant attitudes than men toward all four outgroups studied. Republicans were more prejudiced toward homosexuals and women than were Democrats or Independents. Participants who identified themselves as Christians were less supportive of equality between the sexes than were Catholics, Protestants, or those with no religion Christians were also more prejudiced toward homosexuals than were Catholics or those with no religion. 相似文献

The use of spelling-sound information in both reading and spelling was evaluated by having children read and spell nonwords and five types of words that differed in terms of their regularity for reading and spelling. The subjects were grade 3 children who had been psychometrically defined as good readers and good spellers (“good”), good readers and poor spellers (“mixed”), or poor readers and poor spellers (“poor”). Results indicated that all children attempted to use spelling-sound correspondences in both reading and spelling, although children in both the mixed and the poor groups had weaker knowledge of these correspondences and were less systematic in their use of them. Furthermore, even though the children in the mixed group had been matched with children in the good group on reading comprehension, the number and type of errors made by the mixed subjects on both the reading and spelling tasks were more similar to those of the poor subjects than to those of the good subjects. 相似文献

The influence of perceived somatotype on stereotypes of behavior associated with body build was investigated among 160 male and 140 female Nigerian children in secondary school. In both groups, the perception of subjects' own physiques and discrepancy between their perceived and preferred physiques significantly explained the variance in the character trait scores attributed to body types. In general, the subjects attributed positive character traits to their perceived somatotypes and undesirable traits to the physiques with which they were dissatisfied. Thus, the perception of somatotype and discrepancy between perceived and preferred physique could significantly differentiate the character traits attributed to body build among male and female children. 相似文献

Summary Four experiments were conducted to examine processes in identification and selective adaptation of hues in color perception that exactly parallel processes in identification and adaptation of auditory detectors that provide information for phonemic perception. The first experiment demonstrated an effect of adaptation on identification of blue and green when a hue category center was used as the adaptor; this experiment also assessed recovery from adaptation. Adaptation to one hue was found to shift identification to favor the alternative hue, implicating a single detector underlying hue categorization. The second experiment demonstrated similar effects of adaptation between green and yellow. The third experiment compared the magnitudes of shift following adaptation with a category center, a near-boundary hue, and variously graded adaptation series. Adaptation was found to be related to the category representativeness of the adaptor(s). Results of the third experiment also provided support for the view that adaptation, rather than response bias, is responsible for shifts in the position of identification functions following extended stimulus exposure. The fourth experiment explored the neural loci of adaptation by an interocular transfer test. Hue adaptation was found to occur at both central and peripheral loci. In the four main experiments, reaction times to identify hues in unadapted and adapted states were also analyzed and compared. Subsidiary experiments assessed the effects of stimulus luminance on the magnitude of adaptation. General principles of categorical perception and its underlying bases, including the sweep, magnitude, and symmetry of adaptation, are discussed. The principal findings of these studies provide new data on hue perception which strikingly parallel findings in speech perception. 相似文献

Do contemporary fathers have the same kinds of goals, beliefs, aspirations, and expectations about their children that fathers had 30 years ago? To answer this question, we interviewed 102 White fathers of 133 daughters and 126 sons about the topics probed by Aberle and Naegele (1952). We also asked about how the fathers expressed approval and disapproval of their children's behaviors, about their techniques for encouraging their children to develop the traits the fathers considered desirable, and about the sources of sex education for children. In general, our contemporary fathers mimicked some of the expectations of the earlier group and differed in others. Like the earlier group, some expectations were gender stereotypic. These expectations presumably function to restrict or limit the socialization of their children. More striking were the differences in the two sets of responses. In contrast to the statements from Aberle and Naegele's fathers, our fathers expressed many similar expectations for their daughters and sons. The educational and occupational levels of the fathers and the family composition qualified only a few of the above results. 相似文献

Aggressive behavior inhibition by serotonin and quipazine injected into the amygdala in the rat 总被引:1,自引:0,他引:1
The effects on aggressive behavior, open-field activity, and pain threshold of bilateral microinjections of serotonin (20 micrograms) and quipazine (20 micrograms), the direct serotonergic receptor agonist, into the cortico-medial amygdala were investigated in Wistar rats. Both drugs significantly prolonged the attack latency in isolated killer rats (predatory aggression model), and suppressed the incidence of aggressive postures/attacks in shock-induced fighting test (affective aggression). The only difference in the open-field behavior was the lower number of central square entries in drug-treated compared to saline-injected rats. None of the substances produced any significant change in jump threshold. It is concluded that stimulation of serotonin receptors within the amygdala produces inhibition of affective and muricidal behavior in isolated rats. The effect does not seem to be dependent on changes in general activity and pain sensitivity. 相似文献

Selective attention and priming: Inhibitory and facilitatory effects of ignored primes 总被引:11,自引:0,他引:11
Steven P. Tipper Margaret Cranston 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1985,37(4):591-611
The priming effects of ignored information have been studied in Stroop displays (Neill, 1977) and with spatially superimposed drawings (Tipper, in this issue); naming of probes related to ignored primes is delayed in these experiments (“negative priming”). This negative priming effect is confirmed in a list reading task in Experiment 1, which used partially superimposed letters, and Experiment 2, which used spatially separated letters. Furthermore, Lowe (1979) using Stroop colour words observed that changing the nature of the probe such that it did not require selection from a competing word reversed the priming effects of the ignored word from inhibition to facilitation. Experiment 3 confirmed this observation when subjects selected a red letter from a green letter. Two models are suggested to account for this result. In the first, negative priming is a product of the ignored prime and subsequent probe being encoded both as a stimulus to be ignored and one to be named (Allport, Tipper and Chmiel, in press; Lowe, in press). This dual encoding is ambiguous, requiring further processing before response can be output. The other model suggests that negative priming reflects inhibition of response to ignored information, slowing naming latencies to probe stimuli that require the same response. Experiment 4 attempts to differentiate between the models, and the latter inhibition view is preferred. 相似文献

A modification in scoring the ABC Scale 总被引:1,自引:0,他引:1
Saracho ON 《Journal of personality assessment》1985,49(2):154-155
The scoring procedures for the Articulation of the Body-Concept (ABC) Scale to use with three-, four- and five-year-old children were modified to determine their degree of field-dependence-independence. A total of 300 children, who obtained a score of one or better on the ABC Scale, were administered the Preschool Embedded Figures Test (PEFT) and the ABC Scale. The ABC Scale was scored using its scoring procedures and the scoring procedures for the Goodenough-Harris Drawing Test (GHDT). Scores on the PEFT, ABC Scale and GHDT were correlated with each other. Correlations among all cognitive measures ranged from .88 to .99, which were high and statistically significant (p < .0001). Therefore, the scoring procedures for the GHDT can be substituted in scoring the ABC Scale in assessing young children's field-dependence-independence. 相似文献
