Cognitive ability, personality, and academic performance in adolescence

Does positive thinking predict variance in school grades over and above that predicted by cognitive ability? Six hundred and thirty nine high school students participated in a three-year longitudinal study that predicted grades using cognitive ability and three positive thinking variables – self-esteem, hope, and attributional style. Hope, positive attributional style and cognitive ability predicted higher grades, whilst self-esteem was a less consistent predictor of academic performance. Structural equation modelling revealed significant paths from cognitive ability, gender, and a second order positive thinking factor to grades. The results suggest that intelligence, gender, and positive thinking each play a unique role in predicting academic performance in youth. Some suggestions for further research are made.     

Big-Five personality factors, obesity and 2-year weight gain in Australian adults

The objective of this paper was to examine whether the Big-Five Personality factors were associated with obesity and 2-year weight gain in Australian adults. The sample included 5265 Australian adults aged 25-65 years. Binary logistic regression models indicated that Extraversion, Agreeableness and Neuroticism were cross-sectionally associated with obesity, with Conscientiousness inversely associated with obesity. The longitudinal analyses indicated that Extraversion predicted 2-year weight gain. The relationships between personality and obesity/weight gain were not moderated by age or sex. These results have potentially important implications for developing more effective treatment and prevention strategies for obesity.     

Correlates of conformity in three cultures

The present study sought to investigate the correlates of conformity among two South African and an Australian sample. Employing paper and pencil measures, the following were found to be significant correlates of conformity across the three various groups: Conformers generally have a low level of education, are characterised by their authoritarian attitudes, but do not have authoritarian personalities as measured by the Ray (1976) Directiveness scale. Conformers can be of either sex. By contrast, self-esteem and patriotism were found to be unique correlates, that is, they reflect the cultural milieu of the individual.     

Human Values and Social Identities among Samples of White and Black South Africans

We examined the value correlates of different social identities among two groups of South Africans, those identifying themselves as white Afrikaners or as black South Africans. Respondents indicated the importance of their membership of different groups and also completed indices of National strength and order, and International harmony and equality. Multiple regression analyses showed that the social identities associated with both values for self‐identified Afrikaners were mainly linked with ethnic language (Afrikaans) and religion. Among self‐identified black South Africans, however, the social identities were more encompassing, including the notion of global citizen and South African. The findings are discussed in the light of ongoing political and social change in South Africa and the nature of changing identities, as well as the role of cultural symbols in facilitating in‐group identification among white Afrikaners.     

Personality trait change and life satisfaction in adults: The roles of age and hedonic balance

This paper examines whether changes in personality traits influenced life satisfaction (LS). This involved investigating whether these associations were moderated by age and mediated by hedonic balance (i.e., positive and negative affect). Participants included 11,104 Australian adults aged 18–79 years, with data available from two time points (baseline and 4-year follow up). Latent difference score modeling indicated that increased neuroticism was associated with lower LS, whereas increased extraversion, conscientiousness, and agreeableness were associated with higher LS. These relationships were moderated by age, and were less evident in older adults. Hedonic balance partially mediated the relationships between change in neuroticism and extraversion with LS. These findings provide important insights into longitudinal associations between personality change and LS.     

The relative contribution of scene context and target features to visual search in scenes

Many experiments have shown that knowing a targets visual features improves search performance over knowing the target name. Other experiments have shown that scene context can facilitate object search in natural scenes. In this study, we investigated how scene context and target features affect search performance. We examined two possible sources of information from scene context—the scenes gist and the visual details of the scene—and how they potentially interact with target-feature information. Prior to commencing search, participants were shown a scene and a target cue depicting either a picture or the category name (or no-information control). Using eye movement measures, we investigated how the target features and scene context influenced two components of search: early attentional guidance processes and later verification processes involved in the identification of the target. We found that both scene context and target features improved guidance, but that target features also improved speed of target recognition. Furthermore, we found that a scenes visual details played an important role in improving guidance, much more so than did the scenes gist alone.     

The Eysenck psychoticism dimension and delinquent behaviours among non-criminals: changes across the lifespan?

This study assessed relationships between scores on Eysenck's psychoticism (P) scale and delinquent behaviours among high school and university students. Respondents were 347 high school students (M AGE=15.34 years) and 220 first-year university students (M AGE=19.11 years). There were notable differences across the two groups. Whereas most delinquency items correlated significantly with P among the school students, this was not the case among the university students. It is concluded that, while the P scale predicts most delinquent behaviours among younger respondents, it best predicts more serious delinquent behaviours among non-criminal adults. The results are discussed in the context of previous research using the P scale.     

Attitudes to women in society: the role of social dominance orientation and social values

his research assessed the extent to which attitudes to women in society are predicted by the personality trait social dominance orientation (SDO) as well as the values international harmony and equality (INT) and national strength and order (NAT). Respondents were a community sample of adult non‐students (N = 158). Sex differences were observed on INT and attitudes to women. Multiple regression analyses showed sex differences in the extent to which SDO predicts attitudes to women, while no support was found for the view that social attitudes are underpinned by both security and harmony values. The results are discussed with reference to social dominance theory and the nature of the security value domain. Copyright © 2001 John Wiley & Sons, Ltd.     

Five personality factors and sex: preliminary findings

This study assessed the relationships between the Big Five personality domains, attitudes to sex, and three specific sexual behaviours. Respondents were 123 undergraduate students (51 males; 72 females). Men were found to score significantly higher than women on measures of sexual curiosity and sexual excitement, while women were higher on sexual satisfaction. Neuroticism (N) and Extraversion (E) appeared to be the most important predictors of attitudes to sex, although Conscientiousness (C) and Openness to experience (O) were also implicated. N, C, and Agreeableness (A) were implicated in sexual behaviours. Some suggestions for future research are made.
