Pigeons trained to peck a key for food were periodically presented with tones ending with electrical shock until tone presentation consistently suppressed ongoing pecks. Shock was then discontinued and gradients of stimulus generalization were assessed by presenting tones with frequencies above, below, and at the frequencies of those used to develop conditioned suppression. When the training tones had frequencies at 670 and 1500 cps, resulting gradients were bi-modal with peak suppression at 670 and 1500 cps. Of the other test tones, 1000 cps produced the most suppression. When the training tones had frequencies at 450 and 2250 cps, bi-modal gradients were again obtained with peak suppression to the 450 and 2250 cps tones. Of the other test tones, 1000 cps produced the least suppression. These results support the hypothesis that generalized response tendencies summate. 相似文献

This study was designed to determine the relationships between changes in academic performance and intellective and non-intellective factors. Seventh grade students attending five junior high schools, who had attended selected elementary schools, were tested with the Personal Values Inventory (PVI), a test of academic motivation, shortly after the first seventh-grade marking period. School marks at that marking period and those received the previous year were procured from a self-report included in the PVI. All students had taken the California Achievement Test Battery and Mental Maturity Test as well as the Scholastic Testing Service Work-Study Skills Test in the sixth grade. Factor analysis identified four factors in both boys and girls: intelligence-achievement, academic motivation, academic plans, and youth-culture involvement. While intelligence was found to be mainly unrelated to the criterion, the non-intellective factors, especially academic motivation, bore significant relationships to the changed performance. 相似文献

This investigation of 132 University of Illinois undergraduate women who indicated that they were planning either for a career or homemaking role had three purposes: (a) to cross-validate Hoyt and Kennedy's findings of the measured interests of career and homemaking oriented women; (b) to compare the general values of the two groups; and, (c) to discover differentiated patterns of values and interests. Statistically significant results were: career oriented women higher on the Study of Values theoretical, and Strong Vocational Interest Blank lawyer, psychologist, and physician scales; homemaking oriented women higher on the religious, housewife, home economics teacher, and dietician scales. The results support Hoyt and Kennedy's findings. Four distinctive interest-value patterns were discovered. The results were discussed and precautions for their counseling use were indicated. 相似文献

A tone ending with electrical shock was periodically presented to pigeons while they pecked a key for food. Pairs of birds were run simultaneously under a yoked program which insured that both birds received the same number and temporal distribution of shocks. For one of the birds, shock was always initiated by a peck; for the other, shock was unavoidable. Both procedures led to reduced rates of pecking in the presence of the tone, and gradients of stimulus generalization were obtained. But the effects of response contingent shock extinguished more rapidly than the effects of unavoidable shock. In general, birds exposed to unavoidable shock tended to respond at intermediate rates throughout tone, whereas those exposed to response contingent shock ceased to peck for part or all of the tone period. 相似文献

A scale for assessing the complexity or density of utterances was developed using 10 categories ofsemantic relations (e.g., temporal ordering, causality). The categories are inferable from the particular meanings of the words (e.g., connectives, particular tense variations) used in an utterance. The scale was applied to three samples of subjects to assess its interjudge reliability and to compare the utterances of fourth-, sixth-, and eighth-grade children from middle- and working-class neighborhoods. It was also used to compare the complexity of utterances for different types of visual stimuli (used to elicit language samples). Interjudge reliabilities were more than acceptable for each of the samples, and significant differences in semantic density were found across grade, between children from working-class and middle-class neighborhoods, and for the stimuli used to elicit the utterances. When two of the three types of eliciting visual stimuli were equated for content and exposure conditions, the differences in verbal density between eliciting conditions were not replicated. The usefulness of the scale for assessing utterance density and by implication, comprehension difficulty of utterances and of texts, is discussed.This study was supported in part by a Grant from the National Institute of Education, U.S. Department of Health, Education and Welfare, Complexity in Auditory and Graphics Communication, Project No. 4-470.

The present investigation reported the development and validation of the Knowing Styles Inventory (KSI), a scale to measure connected and separate knowing [M. F. Belenky, B. M. Clinchy, N. R. Goldberger, and J. M. Tarule (1986), Women's Ways of Knowing: The Development of Self, Voice, and Mind New York, Basic Books]. In Study 1, principal components analyses for samples of females (N = 300) and males (N = 253) yielded two components, Connected and Separate Knowing. Studies 2 and 3 focused on females exclusively. The results indicated adequate test—retest reliability and internal consistency for both components. Additionally, Connected Knowing was positively correlated with empathic concern, perspective-taking, social desirability, and the femininity factor of the Bem Sex Role Inventory (BSRI). Separate Knowing was positively correlated with the masculinity factor of the BSRI and negatively correlated with social desirability. Suggestions for future research were presented.The authors wish to thank Jill Mattuck Tarule for the insight that she offered in the early stages of this project, and they wish to acknowledge the contribution of Nicole Bressler who participated in item development. 相似文献

An advantage of first mention—that is, faster access to participants mentioned first in a sentence—has previously been demonstrated only in English. We report three experiments demonstrating that the advantage of first mention occurs also in Spanish sentences, regardless of whether the first-mentioned participants are syntactic subjects, and regardless, too, of whether they are proper names or inanimate objects. Because greater word-order flexibility is allowed in Spanish than in English (e.g., nonpassive object-verb-subject constructions exist in Spanish), these findings provide additional evidence that the advantage of first mention is a general cognitive phenomenon. 相似文献
