Elite athletes and retirement: Identity,choice, and agency

Retirement from elite sport can be highly distressing for athletes, and many report experiencing depression and anxiety in adjusting to this transition. In this article, a discursive psychological approach is employed to explore constructions of choice and identity around elite athletes’ retirements within Australian newsprint media. Within these accounts, three ‘types’ of retirements were identified: retirements occurring in relation to age, injury, or active choice. Retiring with individual agency and at an appropriate time was repeatedly privileged, whereas retiring in different ways was routinely problematised. In privileging particular ways of retiring, certain identity positions were made more accessible than others. Consequently, certain actions and choices are deemed appropriate (or not) for athletes, ultimately constraining decision‐making around retirement. The implications of such limited identity positions and choices are explored in relation to the psychological distress and clinical concerns that emerge among many athletes in the transition out of elite sport.     

An Examination of the Value of the Generation Effect for Learning New Material

The generation effect involves an improvement in memory when learners must complete or modify materials. Several researchers have suggested that this effect involves enhanced access to learners' existing memory representations; therefore, the effect should be less effective with meaningless, low meaningful, or unfamiliar material. In the present study, the authors conducted 4 experiments in which legal nonwords were used, and they found no generation effect. In another 2 experiments in which familiar clichés were contrasted with new sentences and with unfamiliar sentences from textbooks, the results showed a greatly reduced generation effect for the new, unfamiliar material. Those findings suggest that memory strategies that depend on the generation effect will have limited effectiveness when they are applied to new or unfamiliar material.     

A Bayesian Approach for Estimating Mediation Effects With Missing Data

Methodologists have developed mediation analysis techniques for a broad range of substantive applications, yet methods for estimating mediating mechanisms with missing data have been understudied. This study outlined a general Bayesian missing data handling approach that can accommodate mediation analyses with any number of manifest variables. Computer simulation studies showed that the Bayesian approach produced frequentist coverage rates and power estimates that were comparable to those of maximum likelihood with the bias-corrected bootstrap. We share an SAS macro that implements Bayesian estimation and use 2 data analysis examples to demonstrate its use.     

Reading Comprehension in Children with ADHD: Cognitive Underpinnings of the Centrality Deficit

We examined reading comprehension in children with ADHD by assessing their ability to build a coherent mental representation that allows them to recall central and peripheral information. We compared children with ADHD (mean age 9.78) to word reading-matched controls (mean age 9.89) on their ability to retell a passage. We found that even though children with ADHD recalled more central than peripheral information, they showed their greatest deficit, relative to controls, on central information—a centrality deficit (Miller and Keenan, Annals of Dyslexia 59:99–113, 2009). We explored the cognitive underpinnings of this deficit using regressions to compare how well cognitive factors (working memory, inhibition, processing speed, and IQ) predicted the ability to recall central information, after controlling for word reading ability, and whether these cognitive factors interacted with ADHD symptoms. Working memory accounted for the most unique variance. Although previous evidence for reading comprehension difficulties in children with ADHD have been mixed, this study suggests that even when word reading ability is controlled, children with ADHD have difficulty building a coherent mental representation, and this difficulty is likely related to deficits in working memory.     

Reliability and construct validity for scale of rejection of Christianity

A sample of 16 male and 30 female undergraduates completed the Greer and Francis Scale of Rejection of Christianity. The data support the internal consistency reliability and construct validity of the scale for this sample.     

Hippocampus, cortex, and basal ganglia: insights from computational models of complementary learning systems

We present a framework for understanding how the hippocampus, neocortex, and basal ganglia work together to support cognitive and behavioral function in the mammalian brain. This framework is based on computational tradeoffs that arise in neural network models, where achieving one type of learning function requires very different parameters from those necessary to achieve another form of learning. For example, we dissociate the hippocampus from cortex with respect to general levels of activity, learning rate, and level of overlap between activation patterns. Similarly, the frontal cortex and associated basal ganglia system have important neural specializations not required of the posterior cortex system. Taken together, this overall cognitive architecture, which has been implemented in functioning computational models, provides a rich and often subtle means of explaining a wide range of behavioral and cognitive neuroscience data. Here, we summarize recent results in the domains of recognition memory, contextual fear conditioning, effects of basal ganglia lesions on stimulus-response and place learning, and flexible responding.     

Co‐occurrence statistics as a language‐dependent cue for speech segmentation

To what extent can language acquisition be explained in terms of different associative learning mechanisms? It has been hypothesized that distributional regularities in spoken languages are strong enough to elicit statistical learning about dependencies among speech units. Distributional regularities could be a useful cue for word learning even without rich language‐specific knowledge. However, it is not clear how strong and reliable the distributional cues are that humans might use to segment speech. We investigate cross‐linguistic viability of different statistical learning strategies by analyzing child‐directed speech corpora from nine languages and by modeling possible statistics‐based speech segmentations. We show that languages vary as to which statistical segmentation strategies are most successful. The variability of the results can be partially explained by systematic differences between languages, such as rhythmical differences. The results confirm previous findings that different statistical learning strategies are successful in different languages and suggest that infants may have to primarily rely on non‐statistical cues when they begin their process of speech segmentation.     

Self-focused attention and safety behaviors across group therapies for social anxiety disorder

Background: Self-focused attention (SFA) and safety behaviors are two variables implicated in the maintenance of social anxiety disorder (SAD).

Design: The present study examined SFA and safety behaviors across two therapies for SAD, cognitive behavioral group therapy (CBGT) and mindfulness and acceptance-based group therapy (MAGT).

Method: Participants with symptoms meeting criteria for SAD (N?=?137) were randomly assigned to the 12-week-treatment groups (n?=?53 for each condition) or a waitlist control (n?=?31). Variables were assessed at baseline, midtreatment, posttreatment, and a 3-month follow-up.

Results: Both treatment conditions reported significantly lower SFA and safety behaviors compared to control, but did not differ from one another at posttreatment. Mediation analyses supported the following models: (1) safety behaviors mediating the relationship between SFA and social anxiety, and (2) SFA mediating the relationship between safety behaviors and social anxiety. These models were supported for both treatment groups.

Conclusions: Both treatments may have the potential to reduce the SFA and safety behaviors that serve to maintain SAD.
