Is academic buoyancy anything more than adaptive coping?

Abstract

Academic buoyancy refers to a positive, constructive, and adaptive response to the types of challenges and setbacks experienced in a typical and everyday academic setting. In this project we examined whether academic buoyancy explained any additional variance in test anxiety over and above that explained by coping. Two hundred and ninety-eight students in their final two years of compulsory schooling completed self-report measures of academic buoyancy, coping, and test anxiety. Results suggested that buoyancy was inversely related to test anxiety and unrelated to coping. With the exception of test-irrelevant thoughts, test anxiety was positively related to avoidance coping and social support. Test-irrelevant thoughts were inversely related to task focus, unrelated to social support, and positively related to avoidance. A hierarchical regression analysis showed that academic buoyancy explained a significant additional proportion of variance in test anxiety when the variance for coping had already been accounted for. These findings suggest that academic buoyancy can be considered as a distinct construct from that of adaptive coping.     

Correcting Too Much or Too Little? The Performance of Three Chi-Square Corrections

This simulation study investigates the performance of three test statistics, T₁, T₂, and T₃, used to evaluate structural equation model fit under non normal data conditions. T₁ is the well-known mean-adjusted statistic of Satorra and Bentler. T₂ is the mean-and-variance adjusted statistic of Sattertwaithe type where the degrees of freedom is manipulated. T₃ is a recently proposed version of T₂ that does not manipulate degrees of freedom. Discrepancies between these statistics and their nominal chi-square distribution in terms of errors of Type I and Type II are investigated. All statistics are shown to be sensitive to increasing kurtosis in the data, with Type I error rates often far off the nominal level. Under excess kurtosis true models are generally over-rejected by T₁ and under-rejected by T₂ and T₃, which have similar performance in all conditions. Under misspecification there is a loss of power with increasing kurtosis, especially for T₂ and T₃. The coefficient of variation of the nonzero eigenvalues of a certain matrix is shown to be a reliable indicator for the adequacy of these statistics.     

Narrative retelling in children with neurodevelopmental disorders: Is there a role for nonverbal temporal‐sequencing skills?

Oral narrative retelling is often problematic for children with communicative and neurodevelopmental disorders. However, beyond a suggested role of language level, little is known about the basis of narrative performance. In this study we examine whether oral narrative retelling might be associated not just with language level but also with skills related to nonverbal narrative temporal sequencing. A diagnostically heterogeneous sample of Swedish‐speaking children with a full scale IQ >70 was included in the study (N = 55; age 6–9 years). Narrative retelling skills were measured using the three subscores from the bus story test (BST). Independent predictors included (1) temporal sequencing skills according to a picture arrangement test and (2) a language skills factor consisting of definitional vocabulary and receptive grammar. Regression analyses show that language skills predicted BST Sentence Length and Subordinate Clauses subscores, while both temporal sequencing and language were independently linked with the BST Information subscore. When subdividing the sample based on nonverbal temporal sequencing level, a significant subgroup difference was found only for BST Information. Finally, a principal component analysis shows that temporal sequencing and BST Information loaded on a common factor, separately from the language measures. It is concluded that language level is an important correlate of narrative performance more generally in this diagnostically heterogeneous sample, and that nonverbal temporal sequencing functions are important especially for conveying story information. Theoretical and clinical implications are discussed.     

Greater efficiency in attentional processing related to mindfulness meditation

In this study, attentional processing in relation to mindfulness meditation was investigated. Since recent studies have suggested that mindfulness meditation may induce improvements in attentional processing, we have tested 20 expert mindfulness meditators in the attention network test. Their performance was compared to that of 20 age- and gender-matched controls. In addition to attentional network analyses, overall attentional processing was analysed by means of efficiency scores (i.e., accuracy controlled for reaction time). Better orienting and executive attention (reflected by smaller differences in either reaction time or error score, respectively) were observed in the mindfulness meditation group. Furthermore, extensive mindfulness meditation appeared to be related to a reduction of the fraction of errors for responses with the same reaction time. These results provide new insights into differences in attentional processing related to mindfulness meditation and suggest the possibility of increasing the efficiency in attentional processing by extensive mental training.     

Gender Bias and Pluralistic Ignorance in Perceptions of Fitness Assessments

Two studies examined the relationship between cadets' views toward women, specifically, attitudes about fitness testing at the United States Air Force Academy (USAFA). Cadets completed measures of views toward women in society, in the military, at USAFA, and fitness testing. Results revealed that many male cadets held sexist attitudes of women in all categories. Cadets who held egalitarian views of women in society and in the military were more likely to support equitable fitness standards. Furthermore, cadets' personal viewpoints differed from their perception of the entire cadet population viewpoint, creating an environment of pluralistic ignorance. That is, cadets believed the collective was more sexist than themselves, suggesting that a vocal minority who perpetuate sexist attitudes may hinder changes in culture.     

Validation of a TAI Short Form with an Adolescent Sample

Subjects who pretested high or low in hypnotic suggestibility took a creativity test either under hypnosis or in a waking state. All subjects made a global estimate of their general degree of creativity. Greater figural-spatial creativity was exhibited in the hypnosis condition than in the waking condition by both high and low suggestibles. Creativity self-reports were not corroborated by actual creative performance.     

Statistical Significance Levels of Nonparametric Tests Biased by Heterogeneous Variances of Treatment Groups

The statistical significance levels of the Wilcoxon-Mann-Whitney test and the Kruskal-Wallis test are substantially biased by heterogeneous variances of treatment groups—even when sample sizes are equal. Under these conditions, the Type I error probabilities of the nonparametric tests, performed at the .01, .05, and .10 significance levels, increase by as much as 40%-50% in many cases and sometimes as much as 300%. The bias increases systematically as the ratio of standard deviations of treatment groups increases and remains fairly constant for various sample sizes. There is no indication that Type I error probabilities approach the significance level asymptotically as sample size increases.     

An investigation of cognitive test performance across conditions of silence,background noise and music as a function of neuroticism

The present study investigates the role of trait neuroticism on cognitive performance under distraction. Seventy participants were given a personality test and then undertook a number of different cognitive tasks in silence, in the presence of popular music and in background noise. It was predicted that performance on a general intelligence test, a test of abstract reasoning, and a mental arithmetic task would be adversely affected by background sounds. It was predicted that neuroticism would be negatively correlated with performance on the mental arithmetic task but only when the individuals were working in the presence of background sound. Stable vs. unstable participant's performance on a mental arithmetic task during noise was significantly higher as predicted. The results provided partial support for the hypotheses and are discussed with respect to previous findings in the literature on personality (particularly introversion–extraversion) and distraction on cognitive task performance. Limitations are noted.     

Effects of blood alcohol testing programmes on drinking behaviour among driving crash patients in emergency departments: A cluster quasi-experimental study

This study aimed to evaluate the effectiveness of blood alcohol testing in decreasing the prevalence of current one-month drinkers among road traffic crash patients within emergency departments at one, two, and three months after a crash. A cluster quasi-experimental study was conducted on 600 crash patients who visited one of the emergency departments at 21 hospitals in Udon Thani province, Thailand. The hospitals were categorised into a (i) high-adherence hospital group (≥70% of all patients) and (ii) low-adherence hospital group (<70% of all patients) according to the compliance of blood alcohol testing in their emergency departments. The data were collected by a trained nurse using a structured questionnaire. The primary outcome was the prevalence of one-month current drinkers. We included 600 patients: 291 from six hospitals in the high-adherence group and 309 from 15 hospitals in the low-adherence group. The prevalence of one-month current drinkers significantly decreased in both the high-adherence and low-adherence groups. However, the prevalence of current drinkers at two and three months after a crash was not statistically significant compared to that one month prior to a crash (48.0% to 19.3% and 31.7% to 13.8% in the high- and low-adherence hospital groups, respectively; p < 0.05 from McNemar’s test). The effectiveness of blood alcohol testing in decreasing the prevalence of one-month current drinkers among traffic crash patients within emergency departments was observed to be statistically significant only at one month after a crash, and not at two and three months.
