A comparison of ultra-endurance cyclists in a qualifying ultra-cycling race for Paris-Brest-Paris and Race Across America-Swiss cycling marathon

Ultra-endurance events test the adaptation of human physiology to extreme physical and mental demands, high levels of training, motivation, and physical conditioning among participants. To understand basic differences among participants according to the severity of the race, participants in qualifying events for two ultra-endurance cycling races, differing in length and intensity, were compared on measures of anthropometry, training, and support. One race was four times longer, required supporting teams, and racers typically had little sleep, which should lead to the qualifiers being substantially more highly trained than those from the shorter race. The qualifiers in the longer race had greater intensity in training while the qualifiers in the shorter race relied more on training volume. Different strategies and types of training reflected the different demands of the races. Future studies should evaluate personality and motivational differences in ultra-endurance events and between these athletes and athletes in other sports.     

Reduced substance use as a secondary benefit of an indicated cognitive-behavioral adolescent depression prevention program

Our first aim was to test whether a group cognitive-behavioral (CB) depression prevention program reduces substance use escalation over 2-year follow-up relative to two active comparison interventions and a brochure assessment control. Our second aim examined whether reductions in depressive symptoms mediate intervention effects, as posited by the affect-regulation model of substance use. In this indicated prevention trial, 341 high school adolescents at risk for depression because of the presence of elevated depressive symptoms were randomized to a Group CB intervention, group supportive-expressive group intervention, CB bibliotherapy, or educational brochure control condition. Participants in Group CB had significantly lower rates of substance use compared with brochure control participants at both 1- and 2-year follow-up and lower substance use at 2-year follow-up relative to bibliotherapy participants; no other condition differences were significant. Mediational analyses suggested that reductions in depressive symptoms from baseline to posttest accounted for changes in substance use over 2 years for participants in Group CB relative to brochure control participants but did not mediate effects relative to those receiving bibliotherapy. Results suggest that a secondary benefit of this CB group indicated depression prevention program is lower rates of long-term substance use. Findings supported the hypothesis that, relative to a nonactive comparison condition, reductions in depressive symptoms mediated the effects of Group CB prevention on substance use escalation.

Personality and Optimal Experience in Adolescence: Implications for Well-Being and Development

Past research has repeatedly identified relations between optimal experience—or flow—and well-being across the lifespan. In the attempt to identify the conditions favoring this experience, some studies took into account personality traits. While most of them operationalized flow in terms of intensity, we presently focused on perceived occurrence versus absence of flow. Specifically, we investigated the relations between flow occurrence, hedonic and eudaimonic well-being, activities associated with flow, and personality in adolescence. A group of 408 Italian teenagers (mean age = 17.31; SD = 1.13) were administered Flow Questionnaire, Satisfaction with Life Scale, Positive and Negative Affect Schedule, Psychological Well-being Scales, and the Big Five Questionnaire. Participants reporting optimal experience in their lives were compared with those not reporting it. Results showed that adolescents experiencing flow reported higher satisfaction with life, hedonic balance, and psychological well-being than their counterparts. Findings from logistic regression analyses further showed that openness to experience was the sole personality factor predicting flow occurrence, and that no personality factors were predictive of type of activities adolescents associated with flow. Findings point to the promotion of optimal experience among adolescents through the support of curiosity and openness to new experiences in engaging opportunities for action. They further call for the development of an integrated model taking into account both individual predispositions and social and cultural factors in well-being promotion.     

Reciprocal Relations Among Self-Efficacy Beliefs and Prosociality Across Time

ABSTRACT The present study examined the longitudinal relations between individuals' prosociality and their self-efficacy beliefs in regard to emotional regulation and responding empathically to others' needs. The participants were 244 females and 222 males with a mean age of 17 years ( SD =1.5) at T1, 19 years ( SD =1.4) at T2, and 21 years ( SD =1.6) at T3. The findings corroborated the posited paths of relations assigning empathic self-efficacy a major role in predicting the level of individuals' prosociality. Empathic self-efficacy beliefs mediated the relations of regulative emotional self-efficacy beliefs to prosocial tendencies such as caring, sharing, helping, and empathic concern toward others. The posited conceptual model accounted for a significant portion of variance in prosociality and has implications for interventions designed to promote and sustain prosociality.     

Effect of task presentation on students’ performances in introductory statistics courses

Research on academic learning indicates that many students experience major difficulties with introductory statistics and methodology courses. We hypothesized that students’ difficulties may depend in part on the fact that statistics tasks are commonly viewed as related to the threatening domain of math. In two field experiments which we carried out in the ecological context of introductory statistics courses, the representation of a statistics task administered to undergraduate students in Psychology (Study 1; n = 127) and Biology (Study 2; n = 166) was manipulated. In both studies we found that students who reported the least favorable prior attainments in math had their performance thwarted when the task was presented as related to the math domain, whereas no performance impairment was observed when the task was presented as related to the verbal/linguistic domain. Implications of the findings for the design and delivery of introductory statistics and research methodology courses are discussed.

Processing idiomatic expressions: effects of semantic compositionality

Three experiments tested the main claims of the idiom decomposition hypothesis: People have clear intuitions on the semantic compositionality of idiomatic expressions, which determines the syntactic behavior of these expressions and how they are recognized. Experiment 1 showed that intuitions are clear only for a very restricted number of expressions, but for the majority of idioms, they are not consistent across speakers. Experiment 2 failed to support the claim that semantic compositionality influences the syntactic flexibility of idioms. Finally, Experiment 3 showed that idioms are more quickly recognized than their literal counterparts, regardless of compositionality and syntactic flexibility. All of the findings were at odds with the tenets of the idiom decomposition hypothesis. The theoretical implications of the results with respect to idiom processing and the notion of compositionality are discussed.     

Facilitating ambulation and activity in persons with profound multiple disabilities through a visual orientation system

A visual orientation system was employed to help two adults with profound multiple disabilities ambulate to programmed activity destinations and carry out familiar activities. The system consisted of a portable control device and light sources. The person participating in experiment 1 was to operate the control device for activating the programmed destinations (and turning on light sources showing the way to them). The person participating in experiment 2 did not need to operate the control device; this activated each programmed destination automatically. A new destination was activated after a preset time had elapsed from the person reaching the previous destination. Results indicated that both persons used the visual orientation system successfully and thus could reach the destinations and carry out activities on their own. General implications of the findings are discussed. © 1998 John Wiley & Sons, Ltd.     

Couple Adjustment and Differentiation of Self in the United States,Italy, and Spain: A Cross-Cultural Study

This study comprises a first attempt to explore a cross-cultural application of Bowen family systems theory and examines the relationship between differentiation of self and couple adjustment using measurement invariance. A sample of 2,141 individuals (n = 915 from the United States; n = 635 from Italy; n = 591 from Spain) completed measures of differentiation of self (DSI-R; Skowron & Schmitt, J Marital Fam Ther, 29, 2003, 209) and couple adjustment (DAS; Spanier, J Marriage Fam, 38, 1976, 15). Results showed evidence of partial measurement equivalence for the DSI-R across the three samples. Additionally, results from latent regression showed that less emotional cutoff predicted greater couple adjustment in the United States, Spain, and Italy, whereas greater emotional reactivity predicted poorer couple adjustment only in the more collectivistic cultures, Spain and Italy. Our findings are consistent with prior empirical studies, which suggest that emotional cutoff is a strong predictor of relationship adjustment. The use of measurement invariance provides a foundation for future studies to continue employing rigorous statistical methods when examining constructs across different cultures. The findings highlight culture-specific similarities and differences in differentiation that may benefit practitioners by informing psychotherapy with individuals, couples, or families from diverse populations.     

Emotion regulation mediates relationships between mindfulness facets and aggression dimensions

Recent years have witnessed an increase of research on socio-affective factors that can explain individual differences in aggressive tendencies across community and offender populations. Specifically, mindfulness and emotion regulation have emerged as important factors, which could also constitute important prevention and treatment targets. Yet, recent studies have advanced the possibility that mindfulness may also have a “dark” side, being associated with increased levels of aggression-related variables, especially when accounting for the variance associated with emotion regulation. The present study sought to elucidate relationships among mindfulness, emotion regulation, and aggression dimensions (i.e., verbal and physical aggression, anger, and hostility) across violent offender (N = 397) and community (N = 324) samples. Results revealed expected associations between both mindfulness and emotion regulation and aggression dimensions, such that greater impairments in mindfulness and emotion regulation were related to increased levels of aggression across samples. Further, analyses of indirect effects revealed that a latent emotion dysregulation factor accounted for (i.e., mediated) relationships between mindfulness facets and aggression dimensions in both samples. Previously reported positive associations between the residual variance in mindfulness scales (i.e., controlling for emotion regulation) and aggression-related variables were not replicated in the current samples. Taken together, findings suggest that mindfulness and emotion regulation have unequivocal relations with lower levels of aggression, and should therefore be considered as relevant targets for prevention and treatment programs aimed at reducing aggressive tendencies.
