The Balloon Analogue Risk Task (BART) is a behavioral measure that is commonly used to assess risk taking propensity. The primary goal of the present study was to introduce a mobile version of the BART (mBART) that can be included within ambulatory assessment protocols to assess risk taking in daily life. Study 1 compared common BART indices (i.e., total money earned, adjusted average pumps, balloon explosions, and coefficient of variability [CV]) on a single administration of the laboratory BART on a computer and the mBART on a smartphone (n = 78). Results revealed generally consistent relationships between indices of risk taking propensity in both the laboratory BART and mBART. Study 2 administered the mBART as part of a 7-day ecological momentary assessment (EMA) protocol in a population of nondaily smokers (n = 51). Using multi-level models, results suggest that males have greater adjusted average pumps (p = .03), and that a participant’s average CV is negatively related to trait sensation seeking (p = .03) and positively associated with trait positive urgency (p = .04). There were within-person effects of study day (p = .05) and environment (p = .02) with respect to adjusted average pumps such that individuals took greater risks as the study progressed and were riskier when alone compared to with others. Inclusion of the mBART in EMA did not appear to significantly increase participant burden and demonstrated acceptable levels of compliance. These results offer initial evidence supporting the feasibility and utility of the mBART for ambulatory research designs.  相似文献

Relations of toddlers' observed negative affect in high- and low-threat contexts to maternal perceptions of their toddlers' internalizing problems and to mothers' responses to emotions (RTE) for fear and sadness were examined. Child-driven, parent-driven, and reciprocal transactional models across 1 year were directly compared. Two-year-old toddlers (N = 106) participated in lab-based activities to elicit distress, and their negative affect was coded. Mothers completed measures of their child's internalizing behaviors and their responses to their toddler's fear and sadness at ages 2 and 3. At age 2, only negative affect in low-threat contexts was associated with greater internalizing problems. Mothers' punishing and minimizing RTE at age 2 predicted an increase in internalizing problems across 1 year. Age 2 internalizing problems predicted an increase in mother's use of supportive RTE over time. Results highlight the importance of considering the context of toddlers' negative affective displays and supported a reciprocal conceptualization of toddlers' internalizing behaviors and mothers' RTE.  相似文献

This study examines the relationships between phonological awareness, visual-spatial sketchpad (VSSP) functioning and arithmetic attainment in young children. A sample of 42 children had their VSSP functioning and phonological awareness assessed when they were 5 years old. Approximately 12 months later their nonverbal reasoning, vocabulary, arithmetic, and reading attainment were assessed. Together, VSSP functioning, phonological awareness, vocabulary, and nonverbal reasoning predicted 41% of the variation in the children's arithmetic attainment. Only phonological awareness and VSSP functioning were significant independent predictors. In contrast, only phonological awareness was a significant independent predictor of reading attainment. These findings are consistent with phonological awareness influencing both the development of reading and arithmetic, whilst VSSP functioning only impacts on arithmetic development.  相似文献

One's expectancies for reinforcement from eating or from thinness are thought to represent summaries of one's eating-related learning history and to thus influence the development of binge-eating and purging behavior. In a 3-year longitudinal study, the authors tested this hypothesis and the hypothesis that binge eating also influences subsequent expectancy development. The authors used trajectory analysis to identify groups of middle school girls who followed different trajectories of binge eating, purging, eating expectancies, and thinness expectancies. Initial eating and thinness reinforcement expectancies identified girls whose binge eating and purging increased during middle school, and expectancies differentiated girls who began these problem behaviors from girls who did not. Initial binge-eating scores differentiated among eating expectancy developmental trajectories. The onset of most behaviors can be understood in terms of learned expectancies for reinforcement from these behaviors. The same model can be applied to the risk for eating disorders.  相似文献

Three experiments examined effects of measuring self-reported emotional intensity on subsequent self-reported emotional intensity. Across 3 experiments, we induced sadness, envy, and happiness and manipulated the number of emotional intensity measurements. In all experiments, repeated measurement led to weaker intensity of negative emotions than did a single measurement. Although the intensity of happiness was unaffected by repeated measurement, data suggest that measurements interfered with ongoing emotional experience. We suggest that our findings have methodological, conceptual, and practical implications, but perhaps foremost is the warning that social scientists may have greater cause for caution regarding repeated self-report measures than previously thought.  相似文献
