CHILDHOOD SEXUAL ABUSE, CULTURE, AND COPING: A QUALITATIVE STUDY OF LATINAS

The purpose of this study was to articulate a model of how Latinas cope with childhood sexual abuse (CSA) and the ways in which personal and cultural variables influence their coping strategies. Nine women who identified as Latina and as survivors of CSA participated in an in-depth interview. The data were analyzed using a grounded theory methodology. Results suggested that participants' coping efforts were influenced by a variety of cultural factors and that they engaged in a wide range of coping behaviors, all of which served two main functions: (1) seeking relief from negative emotions and (2) protecting one's self from further abuse.     

Association between intermale aggression and genetically-defined tryptophan hydroxylase activity in the mouse brain

The relationship between the genetically defined intensity of intermale aggression and the activity of brain tryptophan hydroxylase (TPH) has been studied in inbred mice. No association between the enzyme activity and the percentage of aggressive mice (reflecting the predisposition to aggressive reaction) was revealed. However, a significant positive interstrain correlation between brain TPH activity and accumulated attacking time (reflecting fight intensity) was identified. No correlation was found between TPH activity and the accumulated attacking time in segregating F2 (BALB × C57BL) mice. In conclusion, TPH is an important, but not the only factor controlling the intensity of intermale aggression in mice. © 1996 Wiley-Liss, Inc.     

Role of 5HT1A receptors in a variety of kinds of aggressive behavior in wild rats and counterparts selected for low defensiveness towards man

The 5HT_1A receptor agonist ipsapirone (10 mg/kg) suppressed shock-induced aggression in wild and domesticated rats but did not affect predatory aggression in either group of animals. Ipsapirone decreased neophobia and inhibited defensive reactions by wild rats towards man in the glove test. [³H]8-OH-DPAT binding, which labels 5HT_1A receptors, was significantly increased in the hypothalamus of domesticated rats in comparison with wild counterparts, while 5HT_1A density was unchanged in the frontal cortex in domesticated animals. In essence, the aggressive reactions contributing to the defensive behavior complex in wild rats appear to be regulated through 5HT_1A receptors. © 1992 Wiley-Liss, Inc.     

The More the Merrier? Sibling Composition and Early Manifestations of Theory of Mind in Toddlers

Sibling relationships are argued to offer a rich social context for the development of young children’s theory of mind (ToM). There is evidence that the presence of siblings, particularly older siblings, may promote preschoolers’ ToM, but it has not been investigated among toddlers. This study evaluated differences in early manifestations of ToM between toddlers in different sibling compositions: 1) without a sibling, 2) with younger siblings only, and 3) with older siblings only. The sample included 227 toddlers who completed 2 tasks assessing their understanding of discrepant desires and visual perspectives. Results indicated that only children and those who had older siblings did not differ from each other on either task. However, on both tasks, toddlers with younger siblings performed significantly more poorly compared with those with older siblings. Moreover, children with younger siblings demonstrated poorer visual-perspective understanding compared with only children. It may be critical to take siblings’ birth order into account when investigating their respective effects on each other’s ToM, especially in toddlerhood.     

语境丰富性和生词重复暴露对儿童附带性词汇学习的影响

考察了重复阅读下语境丰富性和生词重复暴露对儿童附带性新词学习的影响。实验设为三种学习条件:多语境重复、单语境重复、基线。结果显示,在反映词汇加工早期阶段的凝视时间和晚期阶段的总注视时间上,均表现为多语境重复学习后的词汇加工时间显著短于单语境重复条件和基线条件,且后两者间无差异。结果证明,儿童在重复阅读过程中对丰富语境线索的使用是附带性词汇学习发展的主要原因,而生词单纯的重复暴露并未产生明显效果,进一步表明只有在丰富的语境环境下单词的重复才会提高儿童新词学习的质量。关于语境丰富性和重复在附带性词汇学习理论和语文实践教学价值上的启示将被讨论。     

Perceived Parenting Style of Fathers and Iranian Adolescents' Self-efficacy: The Moderating Role of Gender and Education

The authors examined the moderating role of adolescent's gender and father's education on the associations between perceived paternal parenting styles and self-efficacy in a socioeconomical diverse sample of Iranian ado-lescents (n = 382). Results revealed that paternal authoritative parenting was significantly and positively related to self-efficacy. Interestingly, a significant and positive relation was also found between paternal authoritarian parenting and self-efficacy. This finding might have been the result of the fact that this study was conducted as part of a collectivist culture. In addition, the results indicated that boys who perceived their fathers as highly authoritative indicated higher self-efficacy than girls did. Furthermore, the findings demonstrated that higher educational levels attenuate the negative impact of the permissive parenting style on self-efficacy. The present findings underscore the need to focus on the role of gender and father's education when assessing the link between parenting style and adolescents' self-efficacy.     

Gender differences in the motivational processing of facial beauty

Gender may be involved in the motivational processing of facial beauty. This study applied a behavioral probe, known to activate brain motivational regions, to healthy heterosexual subjects. Matched samples of men and women were administered two tasks: (a) key pressing to change the viewing time of average or beautiful female or male facial images, and (b) rating the attractiveness of these images. Men expended more effort (via the key-press task) to extend the viewing time of the beautiful female faces. Women displayed similarly increased effort for beautiful male and female images, but the magnitude of this effort was substantially lower than that of men for beautiful females. Heterosexual facial attractiveness ratings were comparable in both groups. These findings demonstrate heterosexual specificity of facial motivational targets for men, but not for women. Moreover, heightened drive for the pursuit of heterosexual beauty in the face of regular valuational assessments, displayed by men, suggests a gender-specific incentive sensitization phenomenon.     

Living with Long QT Syndrome: A Qualitative Study of Coping with Increased Risk of Sudden Cardiac Death

Long QT syndrome (LQTS) is a congenital disorder associated with increased risk of sudden cardiac death; LQTS patients and their families are offered diagnostic or predictive genetic testing. The purpose of this qualitative study was to investigate the psychosocial aspects of living with LQTS, to identify LQTS patients’ daily life challenges and coping strategies, and to describe their experiences with healthcare services. In-depth interviews were conducted with seven individuals who had been tested for long QT genetic mutation. Four of these participants had an implantable cardiac defibrillator (ICD). The participants reported that early and gradually acquired knowledge of the syndrome was an advantage. They also reported experiencing worries and limitations in daily life, but their main concern was for their children or grandchildren. Healthcare providers’ minimal knowledge of LQTS resulted in uncertainty, misinformation, and even wrong advice regarding treatment. The results suggest that regional centers, with the appropriate expertise, should investigate and counsel LQTS patients and their families.
