To assess the influence of a televised model's vocalizations on the vocal patterns of infant viewers, 32 infants at 6 months of age were presented either a televised adult model repeating a novel phoneme pattern (/ba/ba/ba/ba) or a control televised presentation of adult conversation selected from typical daytime programming. Sequential analyses of infant vocalizations revealed that infants exposed to the televised model altered their vocalization pattern, as indicated by a significant increase over base line levels in their production of a patterned series of discrete vocalizations. Infants exposed to the televised conversation showned no increase in this pattern of vocalization, and none of the infants in the study produced the novel phoneme (/ba/). The results indicate that televised presentation of discrete, repeated vocalizations can have an influence on the vocalization pattern of infants. The potential role of television in infant development is discussed.  相似文献

In designing experiments in which the proximal stimulus is a moving grating (including cases in which the distal stimulus is stationary but eye movements play a significant role), one must consider the effects of the motion of the stimulus on its Fourier components in the spatiotemporal frequency domain. Some of these effects are unexpected and counterintuitive. For example, the Fourier components of a moving grating do not include its stationary (or “instantaneous”) spatial frequency. Thus there is no linear filter that can extract a stationary grating from a moving one. Several useful relations are given for analyzing such stimuli.  相似文献

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns.  相似文献

A battery of measures was used to assess conflict between mothers and young adolescents (females and males, 11 to 15 years of age). Two groups of families, one composed of a distressed clinical sample (N = 38), the other a nondistressed normative sample (N = 40), participated. The assessment battery included retrospective judgments, frequency estimates, self-monitored home recording, and tape-recorded discussion of a home problem. Content of assessment measures tapped aspects of parental control, decisionmaking, self-reported interaction behavior, arguments, interaction behavior rated by independent “blind” observers, frequency and anger-intensity of specific problematic issues, and perceptions of positive and negative behaviors of the other family member. Based on univariate analyses, 21 of the 26 defined variables discriminated significantly in the predicted direction. Maternal and adolescent reports of behavior and independent ratings of tape-recorded interaction emerged as strong and consistent discriminators. Stepwise multivariate discriminant analysis provided successful classification of 100% of the families based on the inclusion of nine variables. In a cross-validation sample, 84% of the families were correctly classified. Implications for systematic outcome research as well as clinical application are discussed.  相似文献

Two experiments were performed in the naturalistic setting of a preschool classroom in order to assess the effects on children's social behavior of nonevaluative teacher attention to children's cooperative or aggressive speech. In Experiment 1, teachers attended to the children's spontaneous cooperative speech for two weeks. Observation of the children's free-play behaviors revealed an increase over baseline levels in both verbal and physical cooperative behaviors as well as a decrease in both verbal and physical aggressive behaviors. In Experiment 2, teachers attended first to the children's spontaneous aggressive speech for one week and then switched their attention to the children's cooperative speech for a second week. Teacher attention to aggressive speech in the first week led to an increase over baseline levels in the children's verbal aggressive behavior as well as a decrease in both verbal and physical cooperative behaviors; however, physical aggression remained unchanged. Teacher attention to cooperative speech in the following week served to reverse the effects of the first week's treatment. The findings were discussed in terms of the sequential relationship between verbal and nonverbal components of cooperative and aggressive social behaviors and the teacher's role in modifying children's performance on these behaviors in the classroom.  相似文献

This study examined, for 221 black and white male and female college students, the relationship between the Motive to Avoid Success (M−s) and: (a) sex and race; (b) congruency, consistency, and differentiation of occupational choice; and (c) occupational aspirations. M−s was assessed by a recent scoring system for verbal TAT cues and occupational choice patterns were analyzed by the Self-Directed Search. The results showed a significant sex difference on M−s. High M−s, in white females predicted well defined, sex-role stereotyped, and low occupational aspirations, but for white males it predicted high aspirations. No significant results were found for black males, and M−s in black females seemed to be related to economic well-being.  相似文献

Several facets of the homemaker job were analyzed in terms of the dynamic relationship between husband and wife. Seventy-one husband and wife pairs completed a questionnaire which assessed satisfaction with the homemaker job, marital satisfaction, distribution of responsibility for homemaker tasks between husband and wife, and other variables. Wives' satisfaction with the homemaker job was found related to the degree to which husbands assumed responsibility for homemaker tasks and to the husbands' attitudes toward women in general. Wives' marital satisfaction was found related to the interaction of wives' employment status (job holder or full-time homemaker) and satisfaction with the homemaker job. Directions for future research in this area were suggested.  相似文献
