Friends, fun, frustration and fantasy: Child motivations for video game play

Although a considerable amount of attention has examined potential positive and negative consequences of video game play in children, relatively little research has examined children’s motivations for using games. The current study hopes to address this gap in the literature by examining children’s motivations for video game play in a large sample of youth (n = 1254). Results indicated that video game use was common, and often a social activity. Social play was mainly predicted by motivations related to socialization, fun/challenge and current stress level. Preference for violent games was more common in males and predicted by fun/challenge motivations and beliefs such games could be cathartic for stress. Children with clinically elevated levels of depressive and ADHD symptoms did not play more games, or more violent games, but were more inclined to endorse catharsis motivations for video game use. Results from this study provide understanding of what motivates children to use games, and how the motivations of children with symptoms of psychosocial problems (as identified via subscales of the Pediatric Symptom Checklist) may differ from others.     

Dimensionality of the Beck Anxiety Inventory in a Polytrauma Sample of OEF/OIF/OND Veterans: Findings From Exploratory and Confirmatory Factor Analysis

The Beck Anxiety Inventory (BAI) is commonly used as a screening instrument for symptoms of anxiety in clinical settings. The factor structure has been researched in a variety of different clinical settings with results ranging from a 2- to 5-factor structure. The purpose of this study was to explore the factor structure of this instrument in a polytrauma veteran sample. A sample of 304 veterans was used for this study. All subjects were administered the BAI screening measure as part of an evaluation in an outpatient polytrauma clinic. Exploratory factor analysis was conducted for half of the sample, followed by confirmatory factor analysis for the remaining sample to determine the best model. Factor analyses revealed that a 5-factor model provided a best fit. It is interesting to note that previously identified models of the BAI with other types of samples did not provide the best fit for this polytrauma sample. The BAI may provide additional information for clinicians when examining the 5-factor model with veterans in polytrauma settings. The factor structure of the BAI includes 1 factor (i.e., personal safety) that may be unique for veterans who have served in combat zones.     

Human Capital Models and the Gender Pay Gap

This paper provides a commentary on the article by Lips (2012), “The Gender Pay Gap: Challenging the Rationalizations, Perceived Equity, Discrimination, and the Limits of Human Capital Models.” It provides some economic background for human capital models that try to explain gender pay gaps, and discusses the limitations of the models. It assesses some of Lips’ criticisms of the model. In contrast to Lips, the author believes that human capital theorists are generally aware of the limitations of their models, and she believes that human capital models make a valuable contribution to the literature on the gender pay gap. The author also uses her own research to illustrate how human capital variables can be combined with variables from psychology and other fields to try to understand the salary differences between men and women in specific professions. The Appendix provides a list of some 2011 and 2012 studies that examine gender differences in pay in various countries and the types of data used.     

Early predictors of letter knowledge

This study examined the influence of phonological memory and rapid naming on the development of letter knowledge. Participants were 77 Dutch children, who were followed from the start of their first kindergarten year (mean age 4 years 6.8 months) to the end of their second kindergarten year. Phonological memory was assessed by a nonword repetition test and a sentence repetition test. Rapid naming involved object naming. The study revealed found a substantial effect of phonological memory on the acquisition of letter knowledge that was particularly related to the ability to repeat nonwords. Vocabulary knowledge did not have an independent effect on letter learning after phonological memory was controlled. The study also showed a small effect of rapid naming on the acquisition of letter knowledge that was independent of the effect of phonological memory. Finally, the study also provided further evidence for a specific relation between phonological memory and vocabulary acquisition.     

Sensory processing, reading, IQ, and attention

Detection thresholds for two visual- and two auditory-processing tasks were obtained for 73 children and young adults who varied broadly in reading ability. A reading-disabled subgroup had significantly higher thresholds than a normal-reading subgroup for the auditory tasks only. When analyzed across the whole group, the auditory tasks and one of the visual tasks, coherent motion detection, were significantly related to word reading. These effects were largely independent of ADHD ratings; however, none of these measures accounted for significant variance in word reading after controlling for full-scale IQ. In contrast, phoneme awareness, rapid naming, and nonword repetition each explained substantial, significant word reading variance after controlling for IQ, suggesting more specific roles for these oral language skills in the development of word reading.     

Disruption of eye movements by ethanol intoxication affects perception of depth from motion parallax

Motion parallax, the ability to recover depth from retinal motion generated by observer translation, is important for visual depth perception. Recent work indicates that the perception of depth from motion parallax relies on the slow eye movement system. It is well known that ethanol intoxication reduces the gain of this system, and this produces the horizontal gaze nystagmus that law enforcement's field sobriety test is intended to reveal. The current study demonstrates that because of its influence on the slow eye movement system, ethanol intoxication impairs the perception of depth from motion parallax. Thresholds in a motion parallax task were significantly increased by acute ethanol intoxication, whereas thresholds for an identical test relying on binocular disparity were unaffected. Perhaps a failure of motion parallax plays a role in alcohol-related driving accidents; because of the effects of alcohol on eye movements, intoxicated drivers may have inaccurate or inadequate information for judging the relative depth of obstacles from motion parallax.     

The damaging effect of confirming feedback on the relation between eyewitness certainty and identification accuracy

The authors investigated eyewitnesses' retrospective certainty (see G. L. Wells & A. L. Bradfield, 1999). The authors hypothesized that extemal influence from the lineup administrator would damage the certainty-accuracy relation by inflating the retrospective certainty of inaccurate eyewitnesses more than that of accurate eyewitnesses (N = 245). Two variables were manipulated: eyewitness accuracy (through the presence or absence of the culprit in the lineup) and feedback (confirming vs. control). Confirming feedback inflated retrospective certainty more for inaccurate eyewitnesses than for accurate eyewitnesses, significantly reducing the certainty-accuracy relation (from r = .58 in the control condition to r = .37 in the confirming feedback condition). Double-blind testing is recommended for lineups to prevent these external influences on eyewitnesses.     

Eyewitness identification: information gain from incriminating and exonerating behaviors

An information-gain approach to the analysis and interpretation of eyewitness identification data is described. The information-gain analysis is grounded in Bayesian statistics, permitting the important role of prior probabilities to be explored. This approach also forces a more complete treatment of the data and reveals important patterns that have escaped previous attention in the eyewitness identification literature. Particularly important is the ability of information-gain analyses to make salient the exonerating value of eyewitness behaviors rather than just their incriminating value. Analyses of sample data sets show how the exonerating value of filler identifications and "not there" responses can actually exceed the incriminating value of identifications of the suspect at certain points in the distribution of prior probabilities.     

Utah youth suicide study: psychological autopsy

We conducted a psychological autopsy study to further understand youth suicide in Utah. While traditional psychological autopsy studies primarily focus on the administration of psychometric measures to identify any underlying diagnosis of mental illness for the suicide decedent, we focused our interviews to identify which contacts in the decedent's life recognized risk factors for suicidal behavior, symptoms of mental illness, as well as barriers to mental health treatment for the decedent. Parents and friends recognized most symptoms universally, although friends better recognized symptoms of substance abuse than any other contact. The study results suggest that parents and friends are the most appropriate individuals for gatekeeper training and, in conjunction with other innovative screening programs, may be an effective strategy in reducing adolescent suicide.     

A test of psychotherapists' and nontherapists' recognition of correct and incorrect process in managing client resistance

Objective

Psychotherapist management of client resistance (i.e., opposition to change or the therapy process) has a significant impact on therapy outcomes. This study aimed at assessing psychotherapists' and nontherapists' abilities to recognise empirically supported correct and erroneous therapist responses to client resistance.

Method

Seventy-eight therapists and 111 nontherapists completed a rapidly administered novel skills test, Therapist Errors in Resistance Management (TERM), assessing recognition of correct and erroneous resistance management.

Results

Participants were, on average, less than half as accurate at recognising therapist errors (recognised below chance levels) compared with correct therapist responses to resistance (recognised above chance levels). Therapists outperformed nontherapists in accurate recognition of therapist responding. However, among the therapist group, greater clinical experience did not predict superior recognition of therapist errors.

Conclusion

These results indicate that therapists and nontherapists alike may have difficulty detecting erroneous therapist responses to resistance, tending to mistake empirically contraindicated directive responses for correct responding. This may reflect the difficult and unintuitive nature of correct resistance responding and may suggest a need for increased training in process acuity and resistance management in therapist education.
