Importance of race,gender, and personality in predicting academic performance

Substantial research has demonstrated that African American students tend to perform more poorly than their White counterparts in terms of academic performance (e.g., Bali & Alvarez). However, this knowledge has proven insufficient in highlighting a clear path for countering this gap in academic achievement. The present study (n = 719) provides evidence that race (African Americans and Whites) interacts with personality in predicting academic performance (i.e., grade point average) in a college setting and that the pattern of effects differs for men and women. Agreeableness reduced race effects for women, and extraversion and openness reduced race effects for men. Our results suggest new avenues for educators and policymakers to consider when attempting to reduce this performance gap.     

Discrimination of English and French orthographic patterns by biliterate children

We investigated whether young English–French biliterate children can distinguish between English and French orthographic patterns. Children in French immersion programs were asked to play a dictionary game when they were in Grade 2 and again when they were in Grade 3. They were shown pseudowords that contained either an English spelling pattern or a French spelling pattern, and they were asked to decide whether each pseudoword should go in an English dictionary or a French dictionary if it became a real word. Comparison groups of monolingual English children, monolingual French children, and English–French bilingual university students were also tested on the task. French immersion students in both grades were above chance in discriminating between the two types of pseudowords but were well below adult performance on the task. Measures obtained in kindergarten showed that early print knowledge had some ability to predict later ability to discriminate between the orthographic patterns of the two languages. Further analyses indicated that exposure to print in each language in Grades 1 to 3 was strongly related to discrimination performance. The findings are interpreted as being consistent with the statistical learning hypothesis.     

Transcoding abilities in typical and atypical mathematics achievers: The role of working memory and procedural and lexical competencies

Transcoding between numerical systems is one of the most basic abilities acquired by children during their early school years. One important topic that requires further exploration is how mathematics proficiency can affect number transcoding. The aim of the current study was to investigate transcoding abilities (i.e., reading Arabic numerals and writing dictation) in Brazilian children with and without mathematics difficulties, focusing on different school grades. We observed that children with learning difficulties in mathematics demonstrated lower achievement in number transcoding in both early and middle elementary school. In early elementary school, difficulties were observed in both the basic numerical lexicon and the management of numerical syntax. In middle elementary school, difficulties appeared mainly in the transcoding of more complex numbers. An error analysis revealed that the children with mathematics difficulties struggled mainly with the acquisition of transcoding rules. Although we confirmed the previous evidence on the impact of working memory capacity on number transcoding, we found that it did not fully account for the observed group differences. The results are discussed in the context of a maturational lag in number transcoding ability in children with mathematics difficulties.     

Mental Health Literacy of Australian Rural Adolescents: An Analysis Using Vignettes and Short Films

The mental health literacy (MHL) of rural adolescents has rarely been investigated. This study examined the MHL of 122 rural‐based adolescents (49 males, 73 females) aged 12–18 years (M = 16, SD = 1) using written vignettes and short films to examine knowledge about depression. For the written vignettes, 68% of the rural adolescents were able to correctly identify someone with depression, which is similar to the findings for metropolitan adolescents; however, knowledge about recovery times and avenues of assistance were below that of their metropolitan peers. Participants were less likely to correctly diagnose depression when suicidal intent was not expressed and when the scenario was presented in the more naturalistic form of a film. This finding raises questions about the place of films and written vignettes in future MHL research.     

Effects of Reward Structures on Academic Performance and Group Processes in a Classroom Setting

Researchers have suggested that cooperative, intergroup competitive, and individualistic reward structures result in different patterns of academic performance and group processes. In this study, we investigated these relationships in an undergraduate business school setting. A reward structure was manipulated across four separate classes, and outcomes were measured using self-reports of group effectiveness, academic performance as graded by instructors, and peer evaluations from group members. The results indicated that group effectiveness was rated significantly higher under the cooperative and no-reward conditions compared to the intergroup competitive reward condition. Peer evaluations in the intergroup competitive condition were significantly lower then those under the other three conditions.     

Use of the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Revised Edition (DC:0–3R) with Canadian Infants and Young Children Prenatally Exposed to Substances

The current study examined the mental health diagnostic profiles of infants and young children prenatally exposed to substances using the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, Revised (DC:0–3R) diagnostic system. Participants were 46 biological mother–infant dyads who were engaged in a clinical program for mothers with substance‐use problems and their young children (aged 10–41 months). Diagnostic information was reported for each of the five axes listed in the DC:0–3R diagnostic system based on file reviews. In addition, the children's socioemotional and adaptive behaviors were assessed using the Child Behavior Checklist, Infant–Toddler Social Emotional Assessment, the Social‐Emotional Scale, and the Adaptive Behavior Assessment System (2nd ed.). In this sample of young children with prenatal substance exposure, a broad range of socioemotional symptoms were evident, with almost one third of the children meeting criteria for at least one Axis I mental health diagnosis. In addition, the majority of dyads demonstrated features of a disordered relationship. Children in more problematic relationships demonstrated higher levels of socioemotional and adaptive functioning difficulties and were more likely to have an Axis I diagnosis than were children in adapted relationships. The importance of early intervention efforts aimed at infants with prenatal substance exposure and their biological mothers is highlighted, with a particular focus on enhancing the quality of the mother–child relationship.     

Changes in Jail Inmates’ community connectedness across the period of incarceration

ABSTRACT

Jails bring inmates into proximity with one another and separate them from the community. Because inmates’ connectedness to one another and to the community influences post-release functioning, understanding risk factors for maladaptive shifts in connectedness may inform interventions. The current study examined changes in jail inmates’ (N = 203) connectedness to the community at large and to the criminal community, and predictors of individual differences in changes over time. Connectedness to both communities did not change on average during incarceration, but younger and less guilt-prone inmates increased more in connectedness to the criminal community than older and more guilt-prone inmates, suggesting connectedness interventions should target individuals exhibiting this constellation of attributes.     

The influence of emotional cues on prospective memory: a systematic review with meta-analyses

ABSTRACT

Remembering to perform a behaviour in the future, prospective memory, is essential to ensuring that people fulfil their intentions. Prospective memory involves committing to memory a cue to action (encoding), and later recognising and acting upon the cue in the environment (retrieval). Prospective memory performance is believed to be influenced by the emotionality of the cues, however the literature is fragmented and inconsistent. We conducted a systematic search to synthesise research on the influence of emotion on prospective memory. Sixty-seven effect sizes were extracted from 17 articles and hypothesised effects tested using three meta-analyses. Overall, prospective memory was enhanced when positively-valenced rather than neutral cues were presented (d?=?0.32). In contrast, negatively-valenced cues did not enhance prospective memory overall (d?=?0.07), but this effect was moderated by the timing of the emotional manipulation. Prospective memory performance was improved when negatively-valenced cues were presented during both encoding and retrieval (d?=?0.40), but undermined when presented only during encoding (d?=??0.25). Moderating effects were also found for cue-focality and whether studies controlled for the arousal level of the cues. The principal finding is that positively-valenced cues improve prospective memory performance and that timing of the manipulation can moderate emotional effects on prospective memory. We offer a new agenda for future empirical work and theorising in this area.     

Suitability Screening During Basic Military Training

Results are presented for suitability screening conducted by the United States Air Force during basic military training. The Lackland Behavioral Questionnaire has been used operationally since 2007, and its use has led to an increase in predictive validity. For the prediction of outcomes during the first 4 years of service, one can identify trainees with a 49% likelihood of being separated for unsuitability and a 56% likelihood of being diagnosed with a mental disorder. A formal suitability screening program allows referrals and recommendations to be made using a combination of empirical evidence and clinical judgment.     

The erosion of CVD diamond by diamond particles

This paper describes the damage features generated by the high-velocity impact of diamond particles on diamond produced by chemical vapour deposition (CVD). Two types of diamond grit - angular and cubo-octahedral - were used to impact the surface of the diamond target at a mean impact velocity of 268?m?s^?1. The main damage features were elastic-plastic radial and lateral cracks. Distorted Hertzian ring cracks were also seen on samples impacted with cubo-octahedral diamond grit. This indicates that, in contrast to previous experiments by the authors using silica sand erodent, Hertzian damage can be generated at this velocity when the mechanical properties of the erodent and target are comparable. Fragmentation of the diamond grit occurred on impact; however, the extent of the degradation was much reduced compared with the silica sand erodent.
