What do we know about early sport specialization? Not much!

In November 2005, the International Olympic Committee's Medical Commission issued a statement on Training the elite child athlete recommending that “more scientific research be done to better identify the parameters of training the elite child athlete”. This paper focuses on a specific issue related to training the child athlete: early specialization. While associations between early specialization and expertise development are highlighted, much research also suggests early specialization is associated with a range of negative consequences affecting physical, psychological, and social development. Alternately, some researchers have proposed that an early diversification approach does not disadvantage athletes in acquiring expertise, and is important for the development of intrinsic motivation and skill transferability. However, this review suggests that inadequate evidence exists to resolve the issue in favor of either approach.     

African American Students at Predominantly White Institutions: A Motivational and Self-Systems Approach to Understanding Retention

Predominantly White institutions have not been as effective as historically Black institutions in retaining and conferring degrees upon African American college students. This review seeks to embed the psychological aspects of the retention process proposed by Bean and Eaton [A psychological model of college student retention. In J. M. Braxton (Ed.), Reworking the student departure puzzle (pp. 48–61). Nashville, TN: Vanderbilt University Press, 2000] in a culturally-sensitive framework and consider how African American students attending PWIs may experience the processes in retention. We first give a brief overview of Bean and Eaton’s [A psychological model of college student retention. In J. M. Braxton (Ed.), Reworking the student departure puzzle (pp. 48–61). Nashville, TN: Vanderbilt University Press, 2000] model of retention, then we propose and discuss revisions to Bean and Eaton’s model that we believe would make the model more applicable to African American students attending predominantly White institutions. Specifically, we address students’ attitudes towards their institution, academic self-efficacy, motivation, achievement goals, attributions, and ethnic and bicultural identity development. The discussion concludes with implications and directions for future study.     

Associative structure of second-order conditioning in humans

Second-order conditioning (SOC; i.e., conditioned responding to S2 as a result of S1–US pairings followed by S2–S1 pairings) is generally explained by either a direct S2→US association or by an associative chain (i.e., S2→S1→US). Previous research found that differences in responses to S2 after S1 was extinguished often depended on the nature of the S2–S1 pairings (i.e., sequential or simultaneous). In two experiments with human participants, we examined the possibility that such differences result from S1 evoking S2 during extinction of S1 following simultaneous but not sequential S2–S1 pairings. This evocation of S2 by S1 following simultaneous pairings may have paired the evoked representation of S2 with absence of the outcome, thereby facilitating mediated extinction of S2. Using sequential S2-S1 pairings, both Experiments 1 and 2 failed to support this account of how extinction of S1 reduced responding to S2. Experiment 1 found that extinguishing S1 reduced responding to S2, while extinguishing S2 had little effect on responses to S1, although forward evocation of S1 during extinction of S2 paired the evoked representation of S1 with absence of the outcome. In Experiment 2, evocation of S2 during S1 nonreinforced trials was prevented because S2–S1 pairings followed (rather than proceeded) S1-alone exposures. Nevertheless, responding to S2 at test mimicked S1 responding. Responding to S2 was high in the context in which S1 had been reinforced and low in the context in which S1 had been nonreinforced. Collectively, these experiments provide additional support for the associative-chain account of SOC.     

Incorporating physical activity‐based interventions in school psychology research and practice: A systematic review

Physical activity provides a myriad of well‐documented social‐emotional, behavioral, and academic benefits for youth. While research suggests that physical activity should be integrated within the school day to support the well‐being of students, an understanding of related empirical work within school psychology research and practice is unclear. School psychologists are well positioned to systematically incorporate physical activity within their intervention practices, particularly given their role and expertise in implementing and evaluating interventions. Authors engaged in a systematic review of 20 years (1998–2018) of physical activity intervention research within 10 peer‐reviewed school psychology journals and six school psychology‐related journals. Authors analyzed 22 studies to glean a comprehensive understanding of the literature base and highlight the ways in which physical activity can be incorporated to support school and student outcomes. Suggestions for research and practice in school psychology are discussed in light of the examined literature.     

Effects of Diagnostic Label and Disease Information on Emotions,Beliefs, and Willingness to Help Older Parents with Osteoarthritis

We studied the impact of the diagnostic label of osteoarthritis and educational information on family members' attributions, perceptions, and willingness to help older parents with pain. Undergraduate students (N = 636) were randomly assigned to one of three conditions where they read vignettes about an older mother with chronic pain, which varied on illness label and educational information. Results indicated that both the osteoarthritis label and osteoarthritis information led to more positive perceptions compared with no label/healthy aging information. Results highlight the importance of diagnosis and education in promoting favorable attributions and increasing willingness to help older adults with osteoarthritis.     

The Impact of Disordered Eating Behavior on College Relationships: A Qualitative Study

The authors explored how college students’ disordered eating behaviors affect their peers. Participants were 8 undergraduate students from a northeastern university with a peer who currently or previously engaged in eating disorder (ED) behaviors. Results from a consensual qualitative analysis provided preliminary evidence that students’ EDs negatively affect peers. Outreach and interventions such as cognitive behavior therapy could be used to assist peers of students with EDs. Researchers should investigate the impact of students’ ED behaviors on peers’ health and academic performance.     

Math fluency is etiologically distinct from untimed math performance, decoding fluency, and untimed reading performance: evidence from a twin study

The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance.
