Postpartum Mothers’ Leisure-Time Exercise Behavior is Linked to Positive Emotion During Partner Discussions

Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors.     

A Comparison of Self-Explanation and Elaborative Interrogation

The purpose of the present study was to examine the effectiveness of two learning strategies, self-explanation and elaborative interrogation, for the retention of scientific facts. University students (N= 55) were asked to learn facts about the cardiovascular system using one of three approaches. Self-explanation participants were required to explain what the facts meant to them and how they related to their prior knowledge. Elaborative interrogation participants answered “why” the facts made sense. Finally, the control group simply repeated the facts aloud. Self-explanation participants significantly outperformed elaborative interrogation and repetition control participants on measures of cued recall and recognition. Elaborative interrogation was no more effective than repetition. Results were discussed in terms of the practicality and flexibility of each approach.     

Teacher Candidates' Perspectives on the Value of a Site-Based Methods Course

Abstract

In the field of teacher education, the disconnect between university-based coursework and practical field experiences has long been a concern. To make teacher preparation coursework more meaningful, some programs partner with P-12 schools to offer site-based courses. Although situated learning for novices in practice-based professions makes sense, more research is needed to determine if, how, and why site-based courses in particular may be beneficial for teacher candidates’ (TCs) learning. In this study, we used surveys and interviews with TCs, who had taken the same site-based literacy methods course, to identify which aspects of the course they found most facilitative of connections between the course content and the field. Our findings suggest working with children in classrooms, course instructors’ involvement at the school, and opportunities to discuss and reflect upon their experiences immediately after they had been in the field were the primary features of a site-based course TCs found valuable.     

Youth exercise intention and past exercise behavior: examining the moderating influences of sex and meeting exercise recommendations

The study purposes were to examine: (a) the determinants of exercise intention and past exercise behavior (PEB) using the theories of reasoned action and planned behavior, and (b) the moderating influences of sex and exercise group (meeting or not meeting exercise guidelines). Participants (n = 676 adolescents) completed self-reported measures of their exercise attitude, subjective norm, perceived behavioral control (PBC), intention, and PEB. We found that attitude, subjective norm, and PBC explained 55% of the variance in intention, and intention and PBC explained 51% of the variance in PEB. While we found sex and exercise group differences across the study measures, we did not find evidence of significant moderation. Thus, the theory constructs predicted intention and PEB similarly across sex and exercise groups.     

The effects of physical exertion on decision-making performance of Australian football umpires

Decision-making is a key component of an umpire’s in-game performance, with each decision potentially having a direct impact on the result of the game. Additionally, umpires have to be physically fit to ensure they keep up with the gameplay. While research has identified the decision-making demands and running demands of umpires separately, few have explored the relationship between them. The aim of this investigation was to examine the relationship between physical exertion and decision-making performance of Australian football umpires at the sub-elite and junior levels. A total of 18 Australian football umpires (sub-elite, n = 10; junior n = 8) performed 10 × 300 m runs, with each repetition immediately followed by a video-based decision-making test, then 1 min of recovery. A Mann–Whitney U assessment indicated a significant difference between the sub-elite and junior level umpires for decision-making accuracy (U = 13.00, z = ?2.43, P = 0.016, r = ?0.5). However, there was no significant difference in response time (U = 28.00, z = ?1.07, P = 0.315, r = ?0.25). The sub-elite umpires completed the running efforts in significantly less time than the junior umpires (P < 0.05). Further, there was no significant correlation between decision-making performance and running times for either skill level (P > 0.05). This suggests decision-making performance may not be affected by physical exertion. Therefore, it may be suggested coaches of football umpires allocate more time to the decision-making development of their umpires instead of focusing largely on the physical fitness side, as is currently the trend.     

Parent-Child Communication about Internet Use and Acceptance of Parental Authority

Structural equation modeling is applied to investigate how parents’ communication with their child about his or her Internet use is linked to the child’s acceptance of parental authority in the context of Internet use, and how this in turn is linked to the child’s social media behavior. This study surveyed children aged 13 to 18 and their mothers and fathers (N = 357 families) and found that acceptance of parental authority is a key factor in the effectiveness of parental mediation. It is recommended that parental mediation is studied as a dynamic process shaped by both parents and children.
