This paper calls for a new approach to the measurement of gender similarities and differences in personality. Critiques of current measures that are based on the measurement of stereotypical masculinity and femininity are reviewed, and an alternative measure is presented. It avoids many of the problems in the other scales by measuring expressiveness and instrumentality in such a way that they are not confounded with variables such as independence or autonomy. Results with this measure in five different samples are presented. These confirm our theoretical definitions of expressiveness and instrumentality, and suggest that only the expressive or relational dimension consistently differentiates samples of women and men.We thank Mary Rothbart for her insightful and constructive comments on an earlier draft; Leisha Sanders, Marcia DeCaro, Vickie Van Nortwick, and Lyn Cogswell for their clerical assistance; the Center for the Study of Women in Society for financial support; and Liza Kuecker and Patricia Gwartney-Gibbs for providing data used in the analysis.

The proposal that peripheral visual changes (cues) tend to summon attention automatically was tested by studying the effect
of peripheral cueing on simple detection latency. Delay between cue onset and target onset, the contingent relationship between
cue location and target location, and instructions to subjects were manipulated. Results showed that a peripheral display
change could capture attention even when the target was far more likely to appear at an uncued location. When subjects were
explicitly informed that targets were likely to appear away from the cued location they were able to suppress this effect,
but were unable completely to reverse it by rapidly orienting attention towards the uncued side. Hence the process appears
to be automatic in the sense that it occurs unless there are explicit instructions to the contrary. With explicit instructions
the processing operation can be suppressed, but not completely reversed.

Previous experimental investigation of the effects of repeating an unfamiliar stimulus suggests that mere exposure breeds
attraction (e.g., Zajonc, 1968). On the other hand, correlational work with naturally occurring stimuli such as names, music,
or landscapes suggests that there is also an overexposure effect: the preference function does rise with familiarity at first
but then reaches a turning point and diminishes. The study (N=72) demonstrates this inverted-U relationship in an experimental setting. The stimuli were synthetic nonsense speech, permitting
exact control of exposure durations and interstimulus intervals. The critical factors for demonstrating the effect are probably
(1) the inclusion of a large number of repetitions, and (2) blocked repetition of each stimulus in a homogeneous sequence
not interspersed with other more or less frequent stimuli. 相似文献

We compare over a two-octave range the tonal, interval, and scale relationships of an ancient Chinese bell ensemble of the Zhou Dynasty and a modern bamboo flute. By using subjective pitches, a tonal system with simple harmonic partials (the flute) could be compared with a tonal system with complex inharmonic partials (the bell). We argue that the underlying musical scales of the bell ensemble and the flute are closely related and lie between an unequal-interval pure-system scale and the just-intonation scale. There is some evidence that a least interval of 60 or 66 cents figures in the flute scale, that both flute and bell scales include a 90-cent interval and a true (1,200-cent) octave, and that neither scale includes a 100-cent interval. Since there is a true octave, the scales cannot be cycles of fifths, and since there is no equal-temperament half-tone (100 cents), the scales cannot be equal in temperament. We conclude that the flute and Zhou bell scales are very similar if not the same. Apparently, strong cultural traditions and human perceptual constancies united to sustain a common flexible musical scale during 2,400 years. 相似文献

This is a report of the completion responses for 40 three-letter word stems (e.g., ABO) produced by 100 undergraduate students at the University of California at San Diego. The report includes a list of the different words that were written as stem completions, their frequency of occurrence as completions, and their frequency of occurrence in English according to published norms. This list of materials is useful for the construction of completion tests for future investigations of direct priming phenomena, and it may provide an important covariate in the analysis of performance on completion tests. Preliminary analyses of the results reveal three primary factors that determine overall performance on a stem-completion test: word frequency, word length, and meanings per word. Analyses of the completions produced for each individual word stem, however, reveal that usually only one of these factors makes a significant contribution to performance. 相似文献

Testicular self-examination (TSE) can lead to early diagnosis and treatment of testicular cancer, the third leading cause of death in young men. We evaluated the effectiveness of a brief and specific checklist for teaching TSE skills. Ten men were videotaped while performing testicular self-examinations before and after training. The TSE training resulted in large and significant increases in the number of TSE steps completed and duration of the TSE. Two urological validation measures supported the improvements observed in the mens' self-examinations. Subjects reported continued performance of TSE during a follow-up telephone interview. This pilot study indicates that a brief and specific checklist is an effective strategy for teaching early cancer detection skills. 相似文献

Cathartic and behavioral treatment procedures for eliminating diurnal and nocturnal primary encopresis were investigated using a multiple-baseline design across four children. The dependent and independent variables measured were appropriate bowel movements, soiling accidents, independent toiletings, and cathartic use. Over 177 reliability observations (home visits) were conducted. For two of the children, treatment with cathartics and child-time remedied their soiling accidents and increased their independent toiletings in 8 to 11 weeks. While the cathartics and child-time increased the rate of appropriate bowel movements, they did not eliminate the soiling accidents with the other two children. Independent toiletings for these two children were achieved after 32 to 39 weeks of treatment when punishment procedures (positive practice, time-out, and hourly toilet sits) were incorporated and the suppositories were faded systematically. 相似文献

Exemplification: The self-presentation of moral character 总被引:1,自引:0,他引:1
How do people come to terms with moral self-presentations and disconfirming behaviors? Subjects were exposed to the self-presentation of either an exemplifier (presenting himself as morally virtuous) or a pragmatist (presenting himself as morally adaptable) and then learned whether the self-presenter had or had not cheated for self-serving reasons in an earlier experiment Subjects clearly distinguished between exploitativeness and hypocrisy in their attributions, and considered a cheating exemplifier more hypocritical and self-deluding, but less exploitative and devious than a cheating pragmatist A second experiment manipulated subjects' involvement with the cheating of an exemplifier and a pragmatist by making half of the subjects its victims As in Experiment 1, uninvolved subjects considered the cheating exemplifier more hypocritical and less exploitative than a cheating pragmatist, however, involved subjects (victims) considered a cheating exemplifier more hypocritical but no less exploitative than a cheating pragmatist The results are discussed in terms of strategic self-presentation and the attribution of moral character 相似文献

It was hypothesized that the extent to which individuals' attitudes guide their subsequent perceptions of and behavior toward the attitude object is a function of the accessibility of those attitudes from memory. A field investigation concerning the 1984 presidential election was conducted as a test of these hypotheses. Attitudes toward each of the two candidates, Reagan and Mondale, and the accessibility of those attitudes, as indicated by the latency of response to the attitudinal inquiry, were measured for a large sample of townspeople months before the election. Judgments of the performance of the candidates during the televised debates served as the measure of subsequent perceptions, and voting served as the measure of subsequent behavior. As predicted, both the attitude-perception and the attitude-behavior relations were moderated by attitude accessibility. The implications of these findings for theoretical models of the processes by which attitudes guide behavior, along with their practical implications for survey research, are discussed. 相似文献
