青少年身体自我的发展特点和性别差异研究 总被引:19,自引:0,他引:19
对1699名青少年学生用自编具有较好信度和效度指标的身体自我量表进行测试。结果表明:青少年学生对身体的满意度从“最满意”到“最不满意”依次是负面特征、相貌特征、性特征、运动特征和身材特征,随年龄的增长其发展呈现波动性,青春期早期和中期呈明显下降趋势,青春期后期有缓慢上升;身体自我在相貌特护、身材特征、性特征、负面特征方面都存在显著的性别差异,男生比女生对身体更满意;城市学生比农村学生对自己的身体更满意。 相似文献

Differentiation of self – a core construct of Bowen's (Bowen, M. (1978). Family therapy in clinical practice. New York: Jason Aronson) family systems theory – was examined as a possible predictor of psychological health and physical health and as a mediator and moderator of the relation between overall functioning and psychological health and physical health. A total of 818 American college students participated (mean age?=?23.72, SD?=?4.79) in this study. Differentiation of self was correlated and was predictive of psychological health, as measured by the Beck depression inventory, and physical health, as measured by body mass index (BMI). A multivariate multiple regression model revealed that differentiation of self partially mediated the effects of overall functioning on depressive symptomatology and on BMI. Results from a hierarchical regression model showed that differentiation of self moderated the relation between overall functioning and depressive symptomatology but did not moderate the relation between overall functioning and BMI. Taken together, these preliminary findings provide initial evidence of the importance of the associations between family systemic factors (differentiation of self) and psychological and physical health factors among American college populations. 相似文献

Studies using Posner’s spatial cueing paradigm have demonstrated that participants can allocate their attention to specific target locations based on the predictiveness of preceding cues. Four experiments were conducted to investigate attentional orienting processes operating in a high probability condition (cues 75% predictive) as compared to a low probability condition (cues 50% predictive) using various types of centrally-presented cues. Spatially-informative cues (arrows and circles with gaps) resulted in cueing effects (CEs) for both probability conditions, with significantly larger CEs in the high probability conditions than the low probability conditions. Participants in the high probability conditions reported little or no awareness of cue–target probabilities after task completion. Our results provide support for an implicit learning account of the proportion valid effect under experimental conditions involving spatially-informative central cues and relatively short stimulus onset asynchronies (SOAs). 相似文献

Maria Dolores de Hevia 《Cognition》2011,121(2):253-255
Past research showing a bias towards the larger non-symbolic number by adults and children in line bisection tasks (de Hevia & Spelke, 2009) has been challenged by Gebuis and Gevers, suggesting that area subtended by the stimulus and not number is responsible for the biases. I review evidence supporting the idea that although sensitivity to number might be relatively affected by visual cues, number is a major, salient property of our environment. The influence of non-numerical cues might be seen as the concurrent processing of dimensions that entail information of magnitude, without implying that number is constructed out of those dimensions. 相似文献

The theory of constructive operators was used as a framework to design two versions of a paradigm (color matching task, CMT) in which items are parametrically ordered in difficulty, and differ only contextually. Items in CMT-Balloon are facilitating, whereas items in CMT-Clown contain misleading cues. Participants of ages 7–14 years and adults (N = 149) were studied. We found significant model-predicted graded differences in performance between the facilitating and misleading tasks, across and within age groups, expressing age versus items’ demand interactions. Younger children were differentially affected by contextual cues. Even though both task versions were highly correlated with a well-established developmental measure of attentional capacity, CMT-Clown, which contained misleading cues, was a better measure of working memory capacity. These results show a need to estimate degree of misleadingness whenever performance levels in working memory or mental attention tasks are compared and interpreted. Developmental profiles of both tasks are discussed in terms of contextual differences and neoPiagetian stages of development. 相似文献

通过向被试呈现代表积极情景线索的材料(一段含有互助、和谐信息的公益短片),运用内隐联想测验(IAT)范式,从内隐社会认知的角度来研究积极情境线索对个体内隐攻击性的影响,并分析这种影响是否具有性别差异。结果表明:未观看积极情景线索材料的被试表现出显著的内隐攻击性,而观看积极情景线索材料的被试的内隐攻击性不显著;积极情景线索的主效应显著,且这一效应不存在性别差异。这说明,积极情景线索能有效抑制个体的内隐攻击性,并支持自我攻击信念IAT是测量个体内隐攻击性的有效工具。 相似文献

对极端膜拜团体造成身心伤害现象的科学研究, 集中在对极端膜拜伤害的界定、测量和机制三个方面。本文的目的, 是梳理这三个主题上的研究脉络, 明晰其中的争议之处和取得的成绩。文本分析表明, 对极端膜拜伤害的界定从“洗脑”转向了“心理虐待”, 对这类伤害的经验观察由个体症状转向了群体行为和经历的描述, 测量方法由传统心理测试工具变成了新型团体心理虐待量表, 膜拜伤害的心理机制研究在综合环境和个人精神特质两种因素的基础上建立了二者交互的病理模型, 表观遗传学和人际神经生物学用于极端膜拜伤害的生理机制研究已见端倪。但是, 迄今对于极端膜拜伤害的学术研究尚未形成范式。 相似文献
