Looking Ahead: Questions for and About Behavioral Scientists and Practitioners

In this article Robin B. Jarrett reflects on the early years in which female investigators were a minority in the field and on her participation in the Trailblazers' panel discussion at the Association for Behavioral and Cognitive Therapies on November 29, 2009. Dr. Jarrett writes these reflections in the form of a letter to current and future professionals (of all demographics) dedicated to behavioral science and its practice; she poses questions about what the future may hold.     

汉语学龄前儿童正字法意识的发展

本研究选择北京地区幼儿园3岁、4岁、5岁儿童各31、48、33名, 采用单部件意识测验和部件位置及功能意识测验系统探查了学龄前儿童的正字法意识各个层面的发展状况。单部件意识测验包括部件替换、部件缺失和部件旋转三个部分; 部件位置及功能意识测验分为假字和非字两个部分, 而非字又包括两形非字和形声非字。结果发现单部件意识测验中, 5岁组儿童在部件替换水平上的得分显著高于3岁组儿童, 而3岁组与4岁组、4岁组与5岁组儿童之间无显著差异; 部件缺失和部件旋转水平上, 三个年龄段的儿童的得分表现出明显的增长趋势。部件位置及功能意识测验中, 假字得分在三个年龄段之间无显著差异; 非字得分随年龄增长显著提高。这些结果表明, 单部件意识在学前期处于不断发展的阶段, 其中对部件替换的非字的拒绝能力发展较早, 部件缺失和部件旋转非字的拒绝能力发展较晚; 部件位置及功能意识在学前期已经开始发展, 3岁儿童已经具有假字符合正字法规则的认识, 但对非字违反部件位置合法性和功能完整性的认识直到4岁左右才开始萌芽, 5岁还未成熟。     

Do older individuals have difficulty processing motion or excluding noise? Implications for safe driving

This study aimed to determine if difficulties extracting signal from noise explained poorer coherent motion thresholds in older individuals, particularly women. In four experimental conditions the contrast of the signal and noise dots used in a random dot kinematogram was manipulated. Coherence thresholds were highest when the signal dots were of a lower contrast than the noise dots and lowest when the signal dots were of a higher contrast than the noise dots. In all conditions the older group had higher coherence thresholds than the younger group, and women had higher thresholds than men. Significant correlations were found between coherence thresholds and self-reported driving difficulties in conditions in which the signal dots had to be extracted from noise only. The results indicate that older individuals have difficulties extracting signal from noise in cluttered visual environments. The implications for safe driving are discussed.     

Gender Segregation in Childhood: A Test of the Interaction Style Theory

The authors investigated the play/interaction-style theory of gender segregation with a sample of 39 children aged 2 to 5 years (primarily Caucasian). According to this theory, children prefer playmates with styles of play or interaction that are similar to their own. Because such styles are sex differentiated, same-sex playmate preference (i.e., gender segregation) results. The authors observed children during free play to determine preferred playmates and gender segregation level, and they used teacher ratings to derive play/interaction-style scores. The authors used a multiple regression approach to path analysis to analyze effects of sex of participant, participants' play/interaction-style scores, playmates' play/interaction-style scores, and degree of gender segregation to determine their effects on one another. The authors observed significant levels of gender segregation, with highly aggressive or active children displaying less segregation than their peers did. However, gender segregation was not associated with a preference for playmates with similar play or interaction styles.     

Gender Differences in Adolescent Self-Esteem: An Exploration of Domains

The relationship between gender and global self-esteem in adolescence, while modest, has been well established, with boys consistently scoring higher than girls. In the present study, we sought to understand gender differences in adolescent self-esteem in terms of its component parts. With a relatively large (n = 545) sample of adolescents, drawn from Grades 8, 10. and 12, we specified 8 domains of adolescent self-esteem (personal security, home/parents, peer popularity, academic competence, attractiveness, personal mastery, psychological permeability, and athletic competence) across a number of different instruments and brought them together into a common assessment superstructure. Gender differences as well as the relative contributions of the different domains to overall self-esteem scores were measured. As predicted, boys attained slightly higher global self-esteem scores than girls did, by a difference of .22 standard deviation units. Contrary to our expectation of more balanced domain effects, boys significantly outperformed girls in 6 of 8 domains, whereas the 2 remaining domains exhibited no significant gender differences. There were no main or interaction effects for grade level. In terms of relative contribution of these domains to global self-esteem for the 2 genders, global self-esteem in boys and girls is predicted in very similar strengths and in the same order of magnitude by identical domains of self-esteem: home/parents, personal security, academic competence, attractiveness, and personal mastery—yielding multiple R ²s from .88 to .91.     

The Performance of Hamsters in the Maze Situation Utilizing Gravitation and the Vestibular Sense as Motivation

The hypotheses of this study of sex differences on a measure of self-esteem are as follows: 1) the scales good, nice, generous, pleasant, dependable, honest, and active will group together to form the outer esteem dimension of the semantic differential; 2) the scales strong, leader, powerful, confident, curious, inventive, sharp, and active will group together to form the inner esteem dimension of the semantic differential; 3) males will score significantly higher than females on the inner esteem dimension of the semantic differential; 4) females will score significantly higher than males on the outer esteem dimension of the semantic differential; 5) there will be a significant difference between the scoring patterns of males and females on the two dimensions of the semantic differential after controlling for the effects of race and social desirability. The sample of 442 sixth through eighth grade students consisted of two subsamples made heterogeneous on race, geographic location, and type of school. The Franks-Marolla Self-Esteem Semantic Differential and the Lunneborg and Lunneborg Child's Social Desirability Scale were administered. The findings support each of the hypotheses and indicate that there is a significant difference between the sexes on the Franks-Marolla Semantic Differential Measure of Self-Esteem. It is concluded that additional research in self-esteem might specify the meaning of sex differences in esteem by measuring esteem relative to an individual's structural social positions rather than measuring esteem in the general and environmentally nonspecific contexts as advocated by some.     

Sense of fairness in the division of labor in close relationships: Procedure and gender role ideology

The present study examined whether the procedures used in establishing a couple's division of labor and each partner's gender role ideology have a significant impact on the perception of fairness in the division of labor. The data collection involved conducting a questionnaire survey of 181 Japanese participants who shared basic household work and paid work. The results from a multiple regression analysis presented a clear pattern of sex differences in the way and degree to which fairness was perceived. In the model for women, the variables of the procedure and gender role ideology had significant predictive power. In particular, the interactive communication procedure was a powerful predictor of women's sense of fairness. In contrast, among men the perception of fairness in the division of labor did not have a significant relation to the variables of the procedure and gender role ideology.     

母亲守门行为与父子依恋的关系：父亲教养投入的中介作用

以597个核心家庭的父亲、母亲和青少年为研究对象,通过问卷调查探讨了母亲守门行为与父子依恋的关系以及父亲教养投入在其中的中介作用。结果表明：（1）母亲开门行为正向预测父子依恋,母亲关门行为负向预测父子依恋;（2）母亲开门行为通过正向预测父亲教养投入的部分中介作用间接预测父子依恋,而母亲关门行为通过负向预测父亲教养投入的部分中介作用间接预测父子依恋。研究结果扩展了母亲守门行为的作用效果研究,对家庭教育实践具有一定的指导意义。     

初中生偶像崇拜及其与生活目标和主观幸福感的关系:性别的调节作用

本研究以3587名初中生为对象,采用问卷测量法,考察了初中生偶像崇拜在性别和年级上的差异,及其与生活目标和主观幸福感的关系,并探究了性别在其中的调节作用。研究发现：（1）女生的偶像崇拜水平显著高于男生的,且偶像崇拜高水平组中女生人数显著多于男生,偶像崇拜低水平组中则相反;初一与初二年级间偶像崇拜的水平及在不同水平上的人数分布均无显著差异。（2）外在生活目标能够正向预测初中生的偶像崇拜水平,其中性别起调节作用,外在生活目标对女生偶像崇拜水平的影响大于男生。（3）性别对偶像崇拜影响初中生主观幸福感上也具有调节作用,即偶像崇拜水平负向预测初中女生的主观幸福感,对男生的主观幸福感则影响不显著。     

青少年抑郁情绪的发展轨迹:界定亚群组及其影响因素

本研究意在分性别考察中国青少年抑郁情绪的发展轨迹及其影响因素。785名男生和859名女生参加了3轮追踪研究,初始测量阶段的年龄跨度为10~16岁,平均年龄分别为12.99±1.84和12.96±1.87岁。采用流调中心抑郁量表(CES-D)简版测量青少年的抑郁情绪。模型拟合的结果显示男女生的抑郁情绪在10~19岁时段皆呈线性增长趋势,其中男生分为两个亚群组,人际关系解释了部分变异;女生分为4个亚群组,学业压力和人际关系均解释了部分变异。
