Development and Evaluation of a Decision Aid About Prenatal Testing for Women of Advanced Maternal Age

Objective: To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing. Setting: A regional genetics center. Design: A before/after study. Interventions: Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions. Subjects: 21 women of advanced maternal age and 17 spouses. Main outcome measures: Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid. Results: After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid. Conclusions: The decision aid shows promise as a useful aid for preparing couples for counseling.     

Self-Discrepancy Across the Life Span

This study examined the developmental trajectory of self-discrepancies in adulthood and the role of self-discrepancies in the maintenance of psychological well-being. One hundred fourteen adults completed mailed surveys that assessed physical health, actual self and ideal self, depression, anxiety, self-esteem, and self-discrepancy. Examination of age differences in actual self and ideal self assessments showed that ideal self ratings converged with actual self ratings for older adults but were significantly different for young and middle-aged adults, which indicated a decline in self-discrepancy with age. Mean scores on the self-discrepancy scale indicated less self-discrepancy in old age, but the differences were not significant. Self-discrepancy mediated the effects of health problems on depression, anxiety, self-esteem, environmental mastery, and self-acceptance. Results support life-span theory suggesting that self-discrepancy declines in old age and that this decline is positively related to psychological well-being.     

A thinking aid

Writing a paper is often a process of discovering what you have to say. A small, inexpensive, "three-dimensional" outline of the paper is a help in guiding the process of discovery. New points can be accurately placed as they appear. The outline grows with the paper. The construction of such an outline is described.     

Age moderates the link between relationship desire and life satisfaction among singles

Higher desire for a romantic partner has been shown to be associated with lower life satisfaction for singles, but research has not considered whether the strength of this association might vary across age groups. We collected data from single participants (N = 3057) across a broad age range (18 to 75 years of age, mean = 36.12, standard deviation [SD] = 12.34) to examine age as a moderator of the relationship between desire for a partner and singles' life satisfaction. Our results suggest that having greater desire for a partner is associated with lower life satisfaction for older (1 SD above the mean or 48.46 years) versus younger (1 SD below the mean or 23.78 years) individuals. We also found some evidence that this age-dependent association was stronger for women than men. Further, this interaction effect remained largely unchanged controlling for participants' attachment anxiety or avoidance. This study highlights the importance of considering how singlehood may play out differently for individuals at different life stages.     

Who gets mad,sad, scared or happy at discipline? Emotion attributions explain child externalizing behaviour

Few studies have linked parental discipline with children's emotional experiences, and not much data explore children's emotional attributions to discipline linked to externalizing behaviour. With a sample from Brazil, this study examines which emotions children most aptly attribute to a protagonist facing spanking, time-out or inductive discipline for norm violations. We hypothesized that anger, sadness, and fear would have higher attribution rates at spanking or time-out, relative to inductive discipline and that happiness would have higher attribution rates at induction relative to the other discipline modalities. We expected these findings to be more pronounced in older children. Based on emotional functions, we also tested the role of neutrality and happiness attributions to discipline in children's externalizing behaviour. A two-way MANOVA, with discipline and child age as explanatory variables, showed that children attributed more anger at time-out or spanking than at induction, and more happiness and neutrality at induction than at either time-out or spanking. Older children attributed significantly more sadness and less fear or neutrality. Hierarchical regressions showed that child externalizing behaviour was negatively related to happy attributions in discipline independently of child emotion situation knowledge or demographics. The results are interpreted in light of a functional view of emotions.     

认知速度在智力结构中重要性的发展研究

结合认知实验方法和心理测量学方法,探讨认知速度在智力结构中的重要性随着年龄增长而发生变化的趋势。研究结果表明,认知速度的确是智力结构中的重要因素,但并不是唯一起决定作用的因素;并且,随着年龄的增长,认知速度在智力结构中的重要性趋向于降低,而智力的元成份在智力结构中的重要性则趋向于提高。     

成年人分类概括力水平的年龄差异及其与记忆的关系

采用威斯康星卡片分类测验（Ｗｉｓｃｏｎｓｉｎｃａｒｄｓｏｒｔｉｎｇｔｅｓｔ,ＷＣＳＴ）对青年组（２０—２５岁）、老年组（６０—６５岁）和老老年组（７０—７５岁）共９０例被试进行分类概括力水平测试,并在结束测试时询问被试与测试有关的几个问题。结果显示：青年组分类概括力水平明显高于老年组;坚持性错误数、非坚持性错误数和总错误数以及坚持性反应数,青年组明显少于老年组;完成作业平均用时间,青年组明显比老年组短;老老年组ＷＣＳＴ多数项目的成绩明显高于老年组;分类概括力水平与记忆密切相关;某些元认知项目与分类概括力水平表现出一致的趋势。     

卡车驾驶员视觉选择性注意研究

采用注意力测验量表,对２８０名男性卡车驾驶员的视觉选择性注意进行了测量。研究发现：事故组与安全组卡车驾驶员的完成时间、漏划数和平均每秒正确删数有很显著差异,错划数有显著差异;事故多发组与安全组卡车驾驶员的完成时间和平均每秒删数有很显著差异,错划数有显著差异;年龄对卡车驾驶员的视觉选择性注意有显著影响,随着年龄的增加,卡车驾驶员完成视觉选择性注意作业的时间增长,漏划数和错划数增多,平均每秒正确删数减少,而４０－５０岁则是卡车驾驶员视觉选择性注意速度和准确性下降的转折点。
