Choosing the best method for local validity estimation: relative accuracy of meta-analysis versus a local study versus Bayes-analysis

This study assessed the relative accuracy of 3 techniques--local validity studies, meta-analysis, and Bayesian analysis--for estimating test validity, incremental validity, and adverse impact in the local selection context. Bayes-analysis involves combining a local study with nonlocal (meta-analytic) validity data. Using tests of cognitive ability and personality (conscientiousness) as predictors, an empirically driven selection scenario illustrates conditions in which each of the 3 estimation techniques performs best. General recommendations are offered for how to estimate local parameters, based on true population variability and the number of studies in the meta-analytic prior. Benefits of empirical Bayesian analysis for personnel selection are demonstrated, and equations are derived to help guide the choice of a local validity technique (i.e., meta-analysis vs. local study vs. Bayes-analysis).     

Implementing the Five-A Model of Technical Refinement: Key Roles of the Sport Psychologist

There is increasing evidence for the significant contribution provided by sport psychologists within applied coaching environments. However, this rarely considers their skills/knowledge being applied when refining athletes’ already learned and well-established motor skills. Therefore, this article focuses on how a sport psychologist might assist a coach and athlete to implement long-term permanent and pressure proof refinements. It highlights key contributions at each stage of the Five-A model—designed to deliver these important outcomes—providing both psychomotor and psychosocial input to the support delivery. By employing these recommendations, sport psychologists can make multiple positive contributions to completion of this challenging task.     

Re-examining selective adaptation: Fatiguing feature detectors,or distributional learning?

When a listener hears many good examples of a /b/ in a row, they are less likely to classify other sounds on, e.g., a /b/-to-/d/ continuum as /b/. This phenomenon is known as selective adaptation and is a well-studied property of speech perception. Traditionally, selective adaptation is seen as a mechanistic property of the speech perception system, and attributed to fatigue in acoustic-phonetic feature detectors. However, recent developments in our understanding of non-linguistic sensory adaptation and higher-level adaptive plasticity in speech perception and language comprehension suggest that it is time to re-visit the phenomenon of selective adaptation. We argue that selective adaptation is better thought of as a computational property of the speech perception system. Drawing on a common thread in recent work on both non-linguistic sensory adaptation and plasticity in language comprehension, we furthermore propose that selective adaptation can be seen as a consequence of distributional learning across multiple levels of representation. This proposal opens up new questions for research on selective adaptation itself, and also suggests that selective adaptation can be an important bridge between work on adaptation in low-level sensory systems and the complicated plasticity of the adult language comprehension system.

The Impact of Community Mental Health Programs for Australian Youth: A Systematic Review

Australia has undergone significant youth mental health reform over the past 10 years, leading to numerous studies examining the effects of community-based mental health care programs for Australian youth. However, no synthesis of this literature currently exists. Therefore, this systematic review aimed to: (1) describe the types of community-based mental health programs that have been delivered to Australian youth in the past 10 years; and (2) examine their impact in improving young people’s mental health symptomology and psychosocial functioning. A systematic search of the peer-reviewed literature was conducted. Studies were included if they evaluated the extent to which such programs improved mental health symptomology (e.g., depression, anxiety, substance use) and/or psychosocial outcomes (e.g., social functioning, school engagement, employment) for Australian youth aged 10–25 years. Thirty-seven studies were included. Four types of community-based youth mental health care programs were identified: therapy (n?=?16), case management (n?=?9), integrated ‘one-stop-shop’ (n?=?6) and lifestyle (n?=?6) programs. The majority of therapeutic programs were effective in reducing mental health symptomology. Case management and integrated approaches consistently yielded significant improvements in both symptomology and psychosocial outcomes. Lifestyle programs were effective in alleviating depressive symptoms, but inconclusive for other outcomes. This review provides support for youth-friendly, systemic, multidisciplinary and integrated assertive outreach models of community mental health care to improve outcomes for young Australians experiencing mental health concerns. Several recommendations for future research are provided to strengthen the local evidence-base supporting community mental health programs to ultimately enhance young people’s life trajectory.

Why don’t synaesthetic colours adapt away?

Synaesthetes persistently perceive certain stimuli as systematically accompanied by illusory colours, even though they know those colours to be illusory. This appears to contrast with cases where a subject??s colour vision adapts to systematic distortions caused by wearing coloured goggles. Given that each case involves longstanding systematic distortion of colour perception that the subjects recognize as such, how can a theory of colour perception explain the fact that perceptual adaptation occurs in one case but not the other? I argue that these cases and the relationship between them can be made sense of in light of an existing view of colour perception. Understanding colours as ways in which objects and surfaces modify light, perceived through grasping patterns and variations in colour appearances, provides a framework from which the cases and their apparent disanalogy can be predicted and explained. This theory??s ability to accommodate these cases constitutes further empirical evidence in its favour.     

Competitiveness across the life span: the feisty fifties

Existing theories on life span changes in confidence or motivation suggest that individuals' preferences to enter competitive situations should gradually decline with age. We examined competitive preferences in a field experiment using real financial stakes in 25- to 75-year-olds (N = 543). The critical dependent variable was whether participants chose to perform a simple mental arithmetic task either under a piece-rate payment schedule (i.e., $.25 per solved item) or a competitive payment schedule ($.50 per solved item if the overall score is better than that of a randomly selected opponent, $0 otherwise). Results revealed that competitive preferences increased across the life span until they peaked around age 50, and dropped thereafter. We also found that throughout, men had a substantially larger preference for competing than women-extending previous findings on college-aged participants. The age/gender differences in preferences were neither accounted for by actual differences in performance nor individuals' subjective confidence. This first systematic attempt to characterize age differences in competitive behavior suggests that a simple decline conception of competitiveness needs to be reconsidered.     

Gender Representation in Philippine Television Advertisements

This study analyzed 254 unduplicated primetime Philippine television advertisements from 2010 for differences in gender representation. Two coders independently coded the entire sample and achieved an intercoder reliability of greater than .700 for each reported variable. The findings are based on chi-square analyses and indicate a high prevalence of gender differences and stereotypes in Philippine television advertisements. For example, more males were shown in the workplace (17.9 % vs. 7.4 %), whereas more females were shown at home (45.9 % vs. 24.5 %); males were generally fully clothed (88.7 % vs. 44.6 %), whereas females were often suggestively dressed (52.7 % vs. 6.6 %); more males than females delivered voiceovers (46.1 % vs. 35.0 %); and product categories were stereotypically associated with gender. The only exception to these traditional, stereotypical gender portrayals was the predominance of female primary characters in television advertisements (58.3 % vs. 41.7 %). Overall, such stereotypical portrayals do not accurately reflect Philippine society, which is considered to be one of the most egalitarian Asian societies with regard to gender. By analyzing Philippine television advertisements, this study intends to close a gap in the still under-researched area of gender representation in developing countries, which could provide a more complete picture of this topic from an international perspective. The similarities and differences between this research and previous studies on this topic in developing and developed countries are examined. The possible effects of such representation on audiences are discussed based on social cognitive theory and cultivation theory.
