The purpose of this content analysis was to examine gender-related portrayals in popular G-rated films. Our research questions addressed the prevalence and nature of males and females in general-audience fare. To answer our research queries, 101 of the top-grossing box office films released theatrically in the United States and Canada from 1990 to early 2005 were assessed. The results showed that males outnumber females by a ratio of 2.57 to 1, which has not changed in fifteen years. Females were more likely than males to be young and depicted traditionally. In terms of personality traits, females were more likely to be smart, good, and beautiful than were males.  相似文献

Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.  相似文献

Psychotherapists often experience stress while providing psychotherapy, in particular when working with difficult presentations such as suicidality. As part of a larger study on the treatment of recently suicidal college students with borderline traits, 6 therapists in training collected their own salivary samples for alpha-amylase (AA) and cortisol (C) analyses immediately before and after sessions with 2 selected clients. On average, samples were collected for the same therapist-patient dyad throughout the year-long study to ensure that data reflected therapist responses across stages of treatment. Therapists also completed a working alliance questionnaire and rated perceived session difficulty immediately after each selected session. Contrary to expectations, therapists demonstrated elevated levels of stress as measured by AA and C at presession relative to postsession levels. Greater session difficulty was related to more pronounced declines in AA, whereas a stronger working alliance was linked to more pronounced reductions in C. Results suggest that physiological stress responses while working with recently suicidal clients with borderline traits occur primarily in terms of session anticipatory anxiety, whereas AA and C changes may be affected differently by factors such as session difficulty and working alliance. This is a pilot study, limited by its sample size, but the design, findings, and inclusion of physiological measures present an initial step in an essential line of research.  相似文献

Language development has long been associated with motor development, particularly manual gesture. We examined a variety of motor abilities – manual gesture including symbolic, meaningless and sequential memory, oral motor control, gross and fine motor control – in 129 children aged 21 months. Language abilities were assessed and cognitive and socio‐economic measures controlled for. Oral motor control was strongly associated with language production (vocabulary and sentence complexity), with some contribution from symbolic abilities. Language comprehension, however, was associated with cognitive and socio‐economic measures. We conclude that symbolic, working memory, and mirror neuron accounts of language–motor control links are limited, but that a common neural and motor substrate for nonverbal and verbal oral movements may drive the motor–language association.  相似文献

The present study investigated the impact of sleep deprivation on several aspects of affective functioning in healthy participants selected from three different developmental periods: early adolescence (ages 10-13), midadolescence (ages 13-16), and adulthood (ages 30-60). Participants completed an affective functioning battery under conditions of sleep deprivation (a maximum of 6.5 hours total sleep time on the first night followed by a maximum of 2 hours total sleep time on the second night) and rest (approximately 7-8 hours total sleep time each night for two consecutive nights). Less positive affect was observed in the sleep-deprived, compared to rested, condition. This effect held for 9 of the 12 positive affect items on the PANAS-C. Participants also reported a greater increase in anxiety during a catastrophizing task and rated the likelihood of potential catastrophes as higher when sleep deprived, relative to when rested. Early adolescents appraised their main worry as more threatening when sleep deprived, relative to when rested. These results support and extend previous research underscoring the adverse affective consequences of sleep deprivation.  相似文献

The present research examined the extent to which interpersonal concerns about rejection based on appearance, or Appearance-based Rejection Sensitivity (Appearance-RS), serves as an indicator of risk for excessive body image concerns. Extending previous research, we examined the association between Appearance-RS and symptoms of body dysmorphic disorder (BDD) and cosmetic surgery attitudes among 106 British university students. Consistent with predictions, Appearance-RS uniquely predicted greater degree of BDD symptoms after controlling for other known predictor variables. Also, as expected, Appearance-RS uniquely predicted acceptance of cosmetic surgery for both intrapersonal and social reasons and greater consideration of having cosmetic surgery in the future. These findings highlight the importance of assessing individuals’ sensitivity to rejection from others based on their physical appearance in investigations of excessive body image concerns.  相似文献

Recent research has identified mothers' mental reflective functioning and verbal mind‐minded comments as important predictors of subsequent infant attachment security. In the present study, we examine associations between mothers' (N = 95) parenting reflectivity expressed in an interview and observed parenting behavior, including verbal mind‐minded comments and interactive behavior during interaction with their 7‐month‐old infants. Parenting reflectivity was coded from the Working Model of the Child Interview. Maternal behavior was assessed via observations of mother–infant interaction during free play and structured teaching tasks. Both maternal appropriate mind‐minded comments as well as other indicators of maternal interactive behavior were coded. Parenting reflectivity was positively correlated with mind‐minded comments and behavioral sensitivity. Hierarchical multiple regression analyses indicated that parenting reflectivity contributed to maternal behavior beyond the contributions of mothers' educational status and depression symptoms. Discussion emphasizes the importance of individual differences in parental capacity to accurately perceive and mentalize their infants' experience, and the consequences of these differences for caregiving behavior.  相似文献

The present study evaluated the interactive behavior of three groups of mothers and their 3-month-old infants in the Face-to-Face Still-Face paradigm. The mothers had either a clinical diagnosis of major depressive disorder (MDD, n = 33) with no comorbidity, a clinical diagnosis of panic disorder (PD, n = 13) with no comorbidity, or no clinical diagnosis (n = 48). The sample was selected to be at otherwise low social and medical risk, and all mothers with PD or MDD were in treatment. The findings indicated that (a) infants of mothers with PD or MDD displayed the traditional still-face and reunion effects described in previous research with nonclinical samples; (b) the 3-month-old infants in this study showed similar, but not identical, gender effects to those described for older infants; and (c) there were no patterns of maternal or infant interactive behavior that were unique to the PD, MDD, or control groups. These results are discussed in light of mothers' risk status, receipt of treatment, severity of illness, and comorbidity of PD and MDD.  相似文献

This article examines the philosophy that Osman bin Bakar has published in English. Beginning with his biography and theoretical groundings, and especially the influences that Greek, Chinese, Indian, and Islamic philosophers have had on his thought, the article then turns to Bakar's philosophy of science, ‘ilm al‐tawhīd, how knowledge about the world should be classified, and especially evolutionary theory within Islamic philosophy. These developments in philosophical grounding provide Bakar with a platform to suggest how science can be used as a vehicle for inter‐civilizational dialogue.  相似文献
