Predictors of Self-Reported Anxiety and Panic Symptoms: An Evaluation of Anxiety Sensitivity, Suffocation Fear, Heart-Focused Anxiety, and Breath-Holding Duration

The purpose of this study was to examine the extent to which anxiety-related individual difference variables predict anxious responding when individuals experience aversive bodily sensations. Thus, we explore several psychological and behavioral predictors of response to a single 25-sec inhalation of 20% carbon dioxide-enriched air in 70 nonclinical participants. Predictor variables included anxiety sensitivity, suffocation fear, heart-focused anxiety, and breath-holding duration. Multiple regression analyses indicated that only anxiety sensitivity significantly predicted postchallenge panic symptoms, whereas both anxiety sensitivity and suffocation fear predicted postchallenge anxiety. These data are in accord with current models of panic disorder that emphasize the role of fear of fear in producing heightened anxiety and panic symptoms and help clarify specific predictors of anxiety-related responding to biological challenge.     

Same‐ and Other‐Sex Victimization: Are the Risk Factors Similar?

Risk factors for same‐ and other‐sex victimization were examined in a longitudinal data set involving 9‐ to 14‐year‐old students. The findings regarding same‐sex victimization supported the view that bullies select personally and interpersonally vulnerable targets in order to maximize their gains in status while minimizing loss of affection within their same‐sex peer group. Although low self‐esteem was a joint predictor of same‐ and other‐sex victimization, rejection and lack of friends among other‐sex peers failed to predict victimization by other‐sex bullies, and being perceived as popular among other‐sex peers increased the risk. Although the findings suggests that interpersonal risk factors for other‐sex victimization differ from those found for same‐sex victimization, they do not provide strong support for heterosexual interest being the basis for other‐sex target selection, as suggested by some previous literature. As about half of the study participants were involved in the KiVa antibullying program, we had the possibility to examine whether the program effects were similar for same‐ and other‐sex victimization. It turned out that in middle schools the program decreased only same‐sex victimization, whereas in elementary school the decrease was observed regardless of the sex composition of bully–victim dyads.

Dysregulated negative emotional reactivity as a predictor of chronic peer victimization in childhood

This study examined the relations of dysregulated negative emotional reactivity, emotional distress, and chronic peer victimization in childhood. A model was proposed whereby dysregulated reactivity was directly and indirectly related to concurrent peer victimization through victimization‐related emotional distress. The model further proposed that dysregulated reactivity directly incrementally predicted longitudinal peer victimization above and beyond the effect of concurrent victimization. Two hundred thirteen 9‐ to 13‐year‐old children and their parents completed measures of dysregulated reactivity and victimization experiences at baseline and 6‐month follow‐up. Children also related narratives of personal victimization experiences at baseline that were coded to assess victimization‐related emotional distress. Model testing strongly supported the direct association of dysregulated reactivity with concurrent victimization and incremental predictive effects of dysregulated reactivity on peer victimization over time. Model testing also provided support for an indirect effect of dysregulated reactivity on concurrent peer victimization through victimization‐related emotional distress. This study demonstrated the powerful role that dysregulated negative emotional reactivity plays in the development of chronic peer victimization over time. Aggr.

The Impact of Neighborhood Factors on the Well-Being of Survivors of Intimate Partner Violence Over Time

Intimate partner violence (IPV) is a pervasive social problem impacting the psychological well-being of millions of US women annually. The extant literature draws our attention to the devastating mental health effects of IPV, but largely overlooks how ecological factors may further explain survivors' well-being. This study examined how neighborhood disadvantage may contribute to survivors' compromised well-being, in addition to the abuse women experienced. Neighborhood disorder and fear of victimization significantly impacted survivors' well-being, over and above abuse. Although between-women effects of neighborhood disorder and fear were unrelated to change in women's depression or quality of life (QOL), significant within-woman effects were detected. Change in neighborhood disorder was negatively associated with change in QOL, and this relationship was fully mediated by fear. While no direct relationship between change in neighborhood disorder and depression was detected, an indirect effect through survivors' fear was revealed. Implications for future research and practice are discussed.     

The development of the Social Bullying Involvement Scales

This study reports findings of a newly developed measure of social bullying based on Underwood's [2003] framework of social aggression. The Social Bullying Involvement Scales (SBIS) consist of four scales measuring the extent to which children experience social victimization, engage in social bullying, witness social bullying, and intervene in social bullying. The sample consisted of 636 participants (311 females and 325 males, age range 11-16 years; 71% White). Confirmatory factor analysis supported a revised version of Underwood's framework for each of the four participant role scales. Internal consistencies for each scale ranged from .93 to .97. Results revealed that social victimization was related to an increase in anxiety, depressive, and externalizing behaviors. Social bullying was associated with an increase in general externalizing behaviors only. Social witnessing was moderately correlated with depression scores. Intervening in social bullying was not linked with psychological maladjustment or externalizing behaviors. The SBIS provides a comprehensive measure of social victimization, social bullying, social witnessing, and social intervening.     

Getting precise and pragmatic about the assessment of bullying: the development of the California Bullying Victimization Scale

Accurate assessment of bullying is essential to intervention planning and evaluation. Limitations to many currently available self-report measures of bullying victimization include a lack of psychometric information, use of the emotionally laden term "bullying" in definition-first approaches to self-report surveys, and not assessing all components of the definition of bullying (chronicity, intentionality, and imbalance of power) in behavioral-based self-report methods. To address these limitations, we developed the California Bullying Victimization Scale (CBVS), which is a self-report scale that measures the three-part definition of bullying without the use of the term bully. We examined test-retest reliability and the concurrent and predictive validity of the CBVS across students in Grades 5-12 in four central California schools. Concurrent validity was assessed by comparing the CBVS with a common, definition-based bullying victimization measure. Predictive validity was examined through the co-administration of measures of psychological well-being. Analysis by grade and gender are included. Results support the test-retest reliability of the CBVS over a 2-week period. The CBVS was significantly, positively correlated with another bullying assessment and was related in expected directions to measures of well-being. Implications for differentiating peer victimization and bullying victimization via self-report measures are discussed.     

A rapid effect of stimulus quality on the durations of individual fixations during reading

We developed a variant of the single fixation replacement paradigm (Yang & McConkie, 2001, 2004) in order to examine the effect of stimulus quality on fixation duration during reading. Subjects' eye movements were monitored while they read passages of text for comprehension. During critical fixations, equal changes to the luminance of the background produced either an increase (Up-Contrast) or a decrease (Down-Contrast) of the contrast of the text. The durations of critical fixations were found to be lengthened in the Down-Contrast but not the Up-Contrast condition. Ex-Gaussian modelling of the distributions of fixation durations showed that the reduction in stimulus quality lengthened the majority of fixations, and a survival analysis estimated the onset of this effect to be approximately 141 ms following fixation onset. Because the stimulus quality of the text during critical fixations could not be predicted or parafoveally previewed prior to foveation, the present effect can be attributed to an immediate effect of stimulus quality on fixation duration.     

提取过程越久记忆保持越好吗？材料难度的调节作用

提取练习效应揭示了提取对记忆保持的关键意义;学习时间分配的有关研究表明提取练习效应的大小可能与材料难度有关。两个实验探讨了提取时间与材料难度对提取练习效应的影响：实验1采用2（提取时间：短,长）×2（材料难度：容易,困难）的混合设计,5分钟后测查记忆保持水平。实验2采用类似设计,将最终测试间隔延长至24小时。结果发现,⑴ 延长提取时间均提高了记忆成绩和记忆保持率。⑵ 即时测试条件下,提取时间较短时,不同难度材料的记忆成绩差异不显著;提取时间较长时,困难材料的记忆成绩高于容易材料;困难材料的记忆保持率在不同提取时间下均高于容易材料。⑶ 延迟测试条件下,无论提取时间长短,困难材料的记忆成绩及保持率均高于容易材料。研究表明,延长提取时间对提取练习效应的影响受材料难度的调节;情境背景和必要难度是解释该调节作用的可能理论框架。     

Children’s effortful control and academic achievement: do relational peer victimization and classroom participation operate as mediators?

Given that early academic achievement is related to numerous developmental outcomes, understanding processes that promote early success in school is important. This study was designed to clarify how students’ (N = 291; M age in fall of kindergarten = 5.66 years, SD = 0.39 year) effortful control, relational peer victimization, and classroom participation relate to achievement, as students progress from kindergarten to first grade. Effortful control and achievement were assessed in kindergarten, classroom participation and relational peer victimization were assessed in the fall of first grade, and achievement was reassessed in the spring of first grade. Classroom participation, but not relational peer victimization, mediated relations between effortful control and first grade standardized and teacher-rated achievement, controlling for kindergarten achievement. Findings suggest that aspects of classroom participation, such as the ability to work independently, may be useful targets of intervention for enhancing academic achievement in young children.     

Comparing methods for measuring peak look duration: Are individual differences observed on screen-based tasks also found in more ecologically valid contexts?

Convergent research points to the importance of studying the ontogenesis of sustained attention during the early years of life, but little research hitherto has compared and contrasted different techniques available for measuring sustained attention. Here, we compare methods that have been used to assess one parameter of sustained attention, namely infants’ peak look duration to novel stimuli. Our focus was to assess whether individual differences in peak look duration are stable across different measurement techniques. In a single cohort of 42 typically developing 11-month-old infants we assessed peak look duration using six different measurement paradigms (four screen-based, two naturalistic). Zero-order correlations suggested that individual differences in peak look duration were stable across all four screen-based paradigms, but no correlations were found between peak look durations observed on the screen-based and the naturalistic paradigms. A factor analysis conducted on the dependent variable of peak look duration identified two factors. All four screen-based tasks loaded onto the first factor, but the two naturalistic tasks did not relate, and mapped onto a different factor. Our results question how individual differences observed on screen-based tasks manifest in more ecologically valid contexts.
