Cognitive Social Learning Variables and the Characteristics of Leaders1

This study explored the potential of a person × situation approach to identifying the characteristics of leaders in a voluntary community organization. A set of variables based on Mischel's “cognitive social learning variables” was operationalized to provide variables which assess the characteristics of individuals in relation to the specific context in which some emerge as leaders. This set of variables was compared with a larger set of traditional demographic and personality variables. Analyses indicated the approximate statistical comparability of the two sets. Advantages of the cognitive social learning approach for understanding and intervening in leader emergence and development in voluntary community organizations are discussed.     

Diagnostic discrepancy and clinical inference: a social-cognitive analysis

This review posits that clinical inference be studied as an instance of human inference. Normative rules for clinical inference may be derived from those for human inference in general, but clinicians choose not to adhere to them, relying instead on possibly biasing and suboptimal methods. A seven-phase model of clinical inference, with each phase containing particular tasks, is presented. Performance on these tasks depends on the effect of cognitive and environmental influences and the application of cognitive strategies, with erroneous performance leading to impaired clinical inference.     

Health beliefs and teenage condom use: a prospective study

The authors investigated the extent to which Health Belief Model (HBM) measures can be used to predict subsequent sexual activity and consistency of condom use among teenagers, especially those who report having new sex partners. Results from a longitudinal survey of sex behavior and HIV-relevant cognitions among 258 sexually active 16 and 18 year olds in Dundee, Scotland, are reported. Participants responded to a confidential postal questionnaire on their demographic characteristics, previous sexual experience, prior condom use, beliefs specified by the HBM, peer norms regarding condom use, and condom use intentions. Measures of sexual behavior and condom use consistency were then included in a follow-up questionnaire 1 year later. Demographic and HBM measures, as determined through discriminant analysis, did not account for significant proportions of variance in the consistency of condom use or mediate the effects of prior sexual experience or demographic measures. The respondents who reported more frequent sexual intercourse were less likely to use condoms consistently while those who had used condoms previously reported more consistent use. Female respondents were less likely than the young men to follow through upon their intentions to consistently use condoms.     

Role conflict and perceptions of gender roles (the case of Israel)

The present study focuses on work—family role conflict among Jewish women employed in a female-typed occupation (secondary school teachers) and a male-typed occupation (university professors). The major hypotheses of the study are that women who work in different occupation types employ different strategies to reduce role conflict and that family roles contribute more to role conflict than work roles. The findings support the hypotheses and show that women in a male-typed occupation spend less time on family and domestic roles, and increase their hours of work. Consequently, their burden at home decreases while their burden at work increases. Because the burden at home contributes more to role conflict than the burden at work, women in male-typed occupations report less role conflict than women in a typically female occupation.An earlier version of this paper was presented at the Society for the Advancement of Socio-Economics Conference, Paris, 1994.

The development of infants' preference for motherese

Generally, infants prefer infant-directed (ID) to adult-directed (AD) speech. Mostly, researchers have used unfamiliar female voices in these studies. We investigated preferences for maternal ID speech in 1- and 4-month-olds. Using a procedure in which infants controlled access to voices by fixating a visual display, infants listened to recordings of natural female ID and AD speech. In Experiment 1, 1-month-olds heard recordings of maternal ID and AD speech, but these infants showed no preference for maternal ID speech. In Experiment 2, 1-month-olds heard the same ID and AD speech tapes but were not familiar with the speakers. Contrary to Experiment 1, these infants preferred ID speech. In Experiment 3, 4-month-olds heard recordings of maternal ID and AD speech and showed a significant preference for ID speech. Collectively, these results suggest that infant attention to ID speech depends on both speaker-general and speaker-specific characteristics, with interesting developmental changes occuring during early infancy.     

Postnatal development of heart rate patterns elicited by an aversive CS and US in cats

Heart rate and motor responses were recorded in cats of different ages during classical conditioning. A deceleratory-acceleratory heart rate pattern observed during the CS-US interval in one and four-week-old kittens is an alpha conditioned response, a potentiated original response to the CS. At eight weeks of age two new distinct patterns of pure acceleration or pure deceleration are acquired during conditioning and in the absence of motor learning. At 12 weeks of age and in adult subjects, heart rate patterns during the CS-US interval become more complex and conditioned motor responses can be observed. A covariance of HR acceleration and motor responses during the CS-US interval is absent in eight-week-old subjects, but quite high in 12-week-old subjects and adult cats. The data are interpreted as suggesting separate elicitatory mechanisms of HR and motor responses which may show synchrony later in ontogeny.
