This study focused on the implications of parents' structuring of their children's home lives for the friendships of their children. Participants were 224 elementary‐school children (108 girls and 116 boys) from four grade levels in two schools in Aix‐en‐Provence, France. Most of the families were of middle or high socio‐economic status. The participating children were seen twice during the same school year in order to assess the stability of their friendship choices and the quality of their friendships. We used Lautrey's (1989) questionnaire in order to assess the parents' styles in the structuring of family life and related child‐rearing practice. This questionnaire delineates three structuring styles: 1) rigid, characterized by considerable imposition of routines with little leeway for exceptional circumstances; 2) flexible, in which established routines can be modified as circumstances dictate; and 3) laissez‐faire, characterized by an absence of predictability and routine. We measured friendship quality by means of Friendship Quality Scale developed by Bukowski, Hoza, and Boivin (1989). This scale consists of 23 items representing five dimensions: companionship, help, security, closeness and conflict. This tool was designed to elicit children's perceptions of a specific relationship with a friend. Results indicated a significant link between parenting style and both of the dimensions of child friendship we studied. Children from homes characterized by a laissez‐faire style of parenting have friendships with more positive features than children from homes with flexible or rigid styles. We also found that friendships were generally less stable and rated as less positive than in similar studies conducted in other countries.  相似文献

In 1948 S. S. Stevens, in his famous Science article, proposed a theory of measurement that radically differed from the dominate theory of the time. The dominate theory held that all strong forms of scientific measurement— for example, those that yielded ratio scales—had to be based on an observable ordering and an observable commutative and associative operation. Stevens proposed different criteria and introduced his method of magnitude estimation. Stevens as well as measurement theorists considered his method to be radically different from those based on commutative and associative operations. Although his method was controversial, it became a standard tool in the behavioral sciences. This article argues that Stevens' method, together with implicit assumptions he made about the scales of measurement it generated, is from a mathematical perspective the same as the measurement process based on commutative and associative operations. The article also provides a theory of qualitative numbers and shows an interesting relationship between qualitative numbers and Stevens' method.  相似文献

Research has shown a tendency of decision makers to overweight small probabilities and to underweight moderate and large probabilities. In standard treatments this is graphically modeled by an inverse S‐shaped probability weighting function. We suggest that emotions play a significant role in the shaping of the probability weighting function. In particular, the weighting function is proposed to be some function of objective probability, expected elation, and expected disappointment. The overweighting of small probabilities results from the anticipated elation after having won, given that winning was very unlikely. The underweighting of large probabilities results from anticipated disappointment after having failed to win, given that winning was very likely. Hence, probability is assumed to influence utility. Three experiments investigate these hypotheses. Experiments 1 and 2 show that a convex function relates probability to surprise. Experiment 3 elicits choice data and further supports the proposed hypotheses. The model adds to the understanding of the cognitive and emotional processes underlying the shape of the probability weighting function. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Listening in aging adults: from discourse comprehension to psychoacoustics.   总被引:4,自引:0,他引:4  
Older adults, whether or not they have clinically significant hearing loss, have more trouble than their younger counterparts understanding speech in everyday life. These age-related difficulties in speech understanding may be attributed to changes in higher-level cognitive processes such as language comprehension, memory, attention, and cognitive slowing, or to lower-level sensory and perceptual processes. A complicating factor in determining how these sources might contribute to age-related declines in speech understanding is that they are highly correlated. Experimenters have typically focused either on cognitive declines or sensory declines in artificially optimized test conditions. In contrast, our approach focuses on the complex interactions between age-related changes in cognitive and perceptual factors that affect spoken language comprehension, especially in nonideal, realistic conditions. In this article, we describe our attempts to systematically investigate sensory-cognitive interactions in controlled experimental situations. We begin by looking at experimental conditions that closely approximate everyday listening, and show that older adults do indeed experience deficits in spoken language comprehension relative to younger adults in these conditions. We then review further experiments designed to isolate more precisely the cognitive and perceptual sources of these age-related differences and how they vary with listening condition. In large part, we find that age-related changes in speech understanding are a consequence of auditory declines.  相似文献

This study was undertaken in an effort to sharpen selection procedures and improve faculty response to the learning needs of students. Eschewing a traditional anticipatory approach in determining suitability for training, the authors undertook a retrospective study to investigate the learning trajectories of candidates. A learning trajectory is defined as the particular way individuals learn, or fail to learn, as they advance through an Institute's training program. The database of this study grew out of the authors' experience with students in classrooms, in supervision, and from discussions about them in Progression, Selection, and The Evaluation of Learning committees. Realizing the reductionism of categorizing a highly complex and diverse group of individuals, the authors, nonetheless, found that candidates tended to group into five rather distinct categories. This paper discusses in detail the characteristics of these five categories and suggests ways in which this grouping may help in both selection and in planning more effective training for candidates. The authors are fully aware that this study has impressionistic qualities and warrants more rigorous research methods, but hope that it will arouse interest in other psychoanalytic centers and stimulate studies to corroborate, refine, or reject the conclusions reached by this group.  相似文献

This paper explores the impact of Nazi ideas and values from education in Napola schools of the National Socialist regime on the development of gender identity during late childhood and adolescence. Difficulties in this realm are illustrated by means of biographical material from a study performed at the Sigmund-Freud Institut in Frankfurt. In this study, interviews were conducted with former Napola students, their children, and grandchildren. A clinical example focuses on the theme of haircutting typical of Napola trainees and the impact this had on the development of a man's gender identity. The examination of two further generations showed that the haircut played an important role in their lives and caused difficulties in the development of masculinity, as well as femininity.  相似文献

Dempster ( Dempster, 1995 ; Dempster & Corkill, 1999 ) proposed that developmental changes in performance on Piagetian tasks could be related to changes in inhibitory efficiency more than to logical development. In this study, the negative priming paradigm was adapted to the class inclusion task in order to investigate the role of inhibition and knowledge levels in the development of class inclusion. Participants were pre‐tested on two inclusion tasks, the standard Piagetian task and Markman's modification task, and assigned to different knowledge levels: empirical, and logical necessity. Children were then tested on a priming version of the class inclusion task. Results showed a negative priming effect, indicating that the irrelevant ‘subclass comparison strategy’ was actively inhibited during the processing of the class inclusion task. This effect was found to vary as a function of knowledge levels, indicating that the need for inhibition was reduced when children had attained logical necessity.  相似文献

Two utilitarian defenses, traceable to Bentham and Mill, arecommonly offered for patents. It is contended that patents induce innovation, and thatpatents induce disclosure of innovation. Patents on some or all of the human genomepose particular challenges for these defenses. In the first instance, patents on nucleotidesequences entail the perverse notion of human reproduction qua infringement. In the second place, when such patents are available (as is presently the case), the two defenses involve a counterfactual claim, viz., that if there were no such patents, biotechnological progress would wane. Even if these challenges are met, concerns about respect for humanity generate opposition to property interests in compounds manipulated outside the human body but significantly homologous to compounds found in humans. This stance about things human might appear to commit the fallacy of division. In a dialogue between a Kantian and a utilitarian, arguments for and against property interests in the human genome are presented.  相似文献
