The Moderating Effect of Anxiety on Development in Atypically Developing Toddlers

In typically developing children, researchers have found that anxiety disorders are associated with poorer intellectual abilities (Davis et al. Journal of Psychopathology and Behavioral Assessment 30:43–51, 2008). The aim of the current study was to examine the impact anxiety symptoms had on the developmental quotients of toddlers. A total of 170 toddlers ranging in age from 17 to 37 months were selected for inclusion in this study, all of whom were at risk for or had a developmental delay. Two factors indicative of behavioral symptoms of anxiety from the Baby and Infant Screen for Children with aUtIsm Traits-Part2 were utilized as the independent variables and the total developmental quotient from the Battelle Developmental Inventory, 2nd Edition was utilized for the dependent variable. Examination of results revealed that atypically developing toddlers with symptoms of anxiety had significantly lower developmental quotients when compared to toddlers without any anxiety symptoms. A discussion of the implications and limitations of this study are included.     

The Effects of Anxiety on Attention Problems and Rule-Breaking Behavior: The Moderating Effect of Work Adjustment in the Workplace

We investigated the relationship between anxiety and attention problems and rule-breaking in a population of subclinical employees and identified the moderating role of work adjustment. After screening 9938 employees at a power company, we obtained a subclinical sample of 269. Our results demonstrate that anxiety is related to attention problems and rule-breaking behavior, and that work adjustment moderates these relationships. Study findings extend our knowledge of adjustment in the workplace, which may act to protect technicians from factors that affect occupational functioning.     

数学焦虑对心算加工的影响

近20年来,研究者逐渐注意到心算加工会受到数学焦虑的影响。文章主要介绍了数学焦虑的涵义、测量及其对心算加工的影响和理论解释。数学焦虑对心算的影响与问题大小效应关系密切。数学焦虑对简单心算问题的影响不大,随着问题难度的增加,数学焦虑效应逐渐明显。此外,数学焦虑还影响着心算的编码、提取以及策略选择等过程。目前的研究多倾向证明加工效能理论,同时抑制理论也是个可选择的理论解释,只是尚缺乏验证研究     

Mediating and Moderating Effects of Social Support in the Relationship Between Social Anxiety and Hope Levels in Children

This study aims to examine whether hope levels are predicted by social anxiety and social support and to investigate if the relationship between social anxiety and children’s hope levels is mediated and moderated by the social support of children. The Social Anxiety Scale for Children, Children’s Hope Scale, and Social Support Appraisals Scale for Children were administrated to a sample of 289 children (148 males and 141 females) enrolled in public school. To determine the relationships between variables, a Pearson correlation coefficient was utilized. Regression-based mediation and moderation analyses assessed whether social support mediates and moderates the relationship between social anxiety and children’s hope levels. Social anxiety and social support both correlated significantly with children’s hope levels; social anxiety had a negative correlation with children’s hope levels, while social support was positively correlated. Regression-based mediation and moderation analyses showed that social support mediates and moderates the relationship between social anxiety and children’s hope levels. The results of the present study emphasized the effects of social support on children; it had a positive effect on hope levels and a negative effect on social anxiety. Based on these results, it is recommended that the social support of children is increased via psycho-education programs for parents, caregivers, and teachers. It is further recommended that social-support-seeking behavior programs are developed in educational and mental health settings.

Effectiveness of the Hamilton Anxiety Rating Scale with Older Generalized Anxiety Disorder Patients

To expand the collection of instruments available for assessment of anxiety in the elderly, this report examined the original and revised Hamilton anxiety scales in a sample of 50 older adults diagnosed with Generalized Anxiety Disorder (GAD) and 93 normal community participants (ages 55–82). Although the revised anxiety scale had better discriminant validity (lower correlation with the revised Hamilton depression scale) than the original anxiety and depression scales, a considerable amount of shared variance still existed (41% shared variance, GAD sample alone; 17% control sample alone; 74% shared variance, both samples combined). Near-perfect group classification was possible using 7 items from the original anxiety scale and 10 items from the revised anxiety scale. Results are discussed in light of their implications for use of the Hamilton anxiety rating scale with older anxiety-disordered patients.     

The Moderating Effects of Accountability on the Conscientiousness-Performance Relationship

The interaction of Conscientiousness and accountability was investigated in the context of performance outcomes using a cognitive performance task, and this interaction was found to be statistically significant. In a laboratory experiment with 95 student-participants, under conditions of accountability, more conscientious individuals performed at higher levels than less conscientious people in support of the hypothesis. Under conditions of no external accountability, the relationship between Conscientiousness and performance was not significant. No main effects were found.

Examining the Relationship Between Mathematics Anxiety and Mathematics Performance: An Instructional Hierarchy Perspective

This study investigated the relationship between mathematics anxiety, fluency, and error rates in basic mathematical operations among college students. College students were assigned to one of two groups (high anxiety or low anxiety) based on results from the Fennema-Sherman Mathematics Anxiety Scale (FSMAS). Both groups were then presented with timed tests in basic mathematical operations (addition, subtraction, multiplication, division, and linear equations). Results suggested that the higher mathematics anxiety group had significantly lower fluency levels across all mathematical operations tests. However, there were no significant differences in error rates between the two groups across any of the probes suggesting that mathematics anxiety is more related to higher levels of learning than to the initial acquisition stage of learning. Discussion focuses on a) stages of learning and their potential relationship to mathematics anxiety, b) the relationship between mathematics anxiety and mathematics performance, and c) directions for future research.     

Perfectionism and Test Anxiety among High-School Students: the Moderating Role of Academic Hardiness

Recent evidence suggests that test anxiety is increasing among students; however, relatively little is known regarding the related factors of test anxiety. The purpose of this study was to (1) examine the relationships between two forms of perfectionism, academic hardiness, and test anxiety, and (2) examine the moderating role of academic hardiness on the association between two types of perfectionism and test anxiety. This study included 520 students ranging from 15 to 21 years of age from eight high schools in Tehran, Iran completed the self-administered questionnaires. The results of Structural Equation Modelling (SEM) revealed that students with high levels of personal standards perfectionism and high levels of academic hardiness were less likely to experience test anxiety, while students with high levels of evaluative concerns perfectionism were more likely to experience test anxiety. A multi-group analysis revealed that academic hardiness moderated the relationship between evaluative concerns perfectionism and test anxiety. These findings enhance existing literature by revealing moderating processes that explain how perfectionism effects test anxiety.     

时距知觉中的情绪效应

情绪极易影响时距知觉,致使主观时距偏离客观时距。新近研究者们结合日趋成熟的标量计时模型及神经学相关依据,并通过采用标准化情绪诱发材料的实验研究,较为系统地解释了情绪的生理唤醒和注意唤醒两种成分各自对内部计时机制造成的干扰效应。研究发现,两种效应中前者会加长主观时距而后者会使其缩短,且分别有不同的发生特点。该文在介绍国内外关于时距知觉中的情绪效应的新近研究基础上,提出应从探索两种效应的分离方法、考虑记忆效应因素以及增加实验自变量的数目和取值水平三个方面来开展进一步的研究

Naturalistic Partial Sleep Deprivation Leads to Greater Next-Day Anxiety: The Moderating Role of Baseline Anxiety and Depression

The detrimental effects of insufficient sleep on emotional functioning have been well established. Total sleep deprivation usually leads to increased anxiety and depressive symptoms the following day. However, no study has yet examined the relationships between unmanipulated partial sleep deprivation and next-day symptoms of anxiety and depression in everyday life, which this study sought to characterize. Participants (N = 94) completed daily diary surveys twice per day for 2 weeks without instructions to alter their sleep in any way. Nights of spontaneous, naturally occurring partial sleep deprivation were followed by increased levels of self-reported symptoms of anxious arousal the next day, but were unrelated to next-day symptoms of anhedonic depression or general distress. The relationship between partial sleep deprivation and next-day anxious arousal was found to be moderated by both baseline depressive symptoms and anxiety such that individuals reporting higher levels of depression or anxiety at baseline showed relatively greater increases in symptoms of anxiety following partial sleep deprivation. These results suggest that partial sleep deprivation occurring in everyday life can lead to higher next-day levels of anxious arousal, a relationship that is particularly deleterious for individuals with higher overall levels of anxiety or depressive symptoms.     

人际情绪调节与内隐/外显积极情绪的关系:情绪调节困难的调节效应与表达抑制的中介效应

人际情绪调节是重要的社会性情绪调节方式,为阐明其与积极情绪的关系,采用人际情绪调节量表、内隐与外显积极情绪量表、表达抑制量表和情绪调节困难量表进行了调查。1159名被试的分析结果表明：（1）人际情绪调节显著正向预测内隐与外显积极情绪;（2）且情绪调节困难是人际情绪调节预测内隐积极情绪的调节变量;（3）表达抑制是人际情绪调节预测外显积极情绪的中介变量。这表明运用人际情绪调节可增加积极情绪,但是其作用效果与个体的情绪特质相关。

Examining the Effects of Exercise on Pattern Separation and the Moderating Effects of Mood Symptoms

Aerobic exercise has broad cognitive benefits. One target of interest is enhanced memory. The present study explored pattern separation as a specific memory process that could be sensitive to acute and regular exercise and clinically significant for disorders (e.g., depression) characterized by cognitive-affective deficits and hippocampal impairment. In a within-subjects design, participants (N = 69) attended two visits during which they repeated a behavioral pattern separation task at rest and after an activity (cycling, stretching). Regular exercise habits, demographics, mood and anxiety symptoms, and recognition memory capacity were also measured. More regular exercise predicted better resting pattern separation, t(62) = 2.13, b = 1.74, p = .037. Age moderated this effect, t(61) = 2.35, b = .25, p = .02; exercise most strongly predicted performance among middle-age participants. There was no main effect of activity condition on post-activity performance, t(61) = .67, p = .51. However, with significant heterogeneity in reported mood symptoms and regular exercise habits, there was a three-way interaction between condition, regular exercise, and depression, t(55) = 2.08, b = .22, p = .04. Relative to stretching, cycling appears to have enhanced the benefit of regular exercise for pattern separation performance; however, this was evident among participants with mild to no symptoms of depression, but absent among participants with moderate to severe symptoms. Results have implications for how exercise might protect against declines in pattern separation. Future research should explore exercise’s potential as a prevention tool or early intervention for pattern separation and related clinical outcomes.
