The relationship between aggression in children and locus of control beliefs

Gender differences are evident in the etiology and maintenance of aggressive behavior (which is on the increase for both male and female youths), but the explanatory models that have been proposed, including social learning theory and information processing models, are more appropriate for boys than for girls. In an attempt to elucidate processes underlying aggression, particularly for girls, the authors explored locus of control as a cognitive variable possibly related to aggressive behavior. The relationships between teacher-reported aggression and 3 types of locus of control (internal, powerful other, and unknown) for success and failure experiences were investigated. For girls, aggressive behavior was positively related to internal and unknown locus of control. In contrast, boys' aggressive behavior was unrelated to internal locus of control beliefs and negatively related to external locus of control beliefs. Possible explanatory mechanisms for the relationship between locus of control beliefs and aggression are discussed. The present study contributes to the understanding of aggression in girls and points to different processes underlying girls' and boys' aggression.     

PRESENTISM,PERSISTENCE AND COMPOSITION

Pace Benovsky's ‘Presentism and Persistence,’ presentism is compatible with perdurantism, tropes and bundle‐of‐universals theories of persisting objects. I demonstrate how the resemblance, causation and precedence relations that tie stages together can be accommodated within an ersatzer presentist framework. The presentist account of these relations is then used to delineate a presentist‐friendly account of the inter‐temporal composition required for making worms out of stages. The defense of presentist trope theory shows how properties with indexes other than t may be said to exist at t. This involves an account of how times other than t exist at t, and how times may be multiply located at any given time. Benovsky's objection to bundles of universals is shown to assume that a bundle of properties must have the properties of its element properties.     

Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.     

The frame turns also: Factors in differential rotation in pictures

When pictures of simple shapes (square, diamond) were seen frontally and obliquely, (1) the shapes with a deeper extent into pictured space underwent morerotation (Goldstein, 1979), which is an apparent turning to keep an orientation toward an observer’s changing position; (2) there was little effect of whether the observer knew the picture surface’s orientation in real space, except that such knowledge could prevent multistability; and (3) depicted picture frames also rotated. In other experiments, figural and frame rotations were independent of each other, and rotation was shown for real frames. The rotation of depthless depictions suggests that at least two rotational factors exist, one that involves the object’s virtual depth and one that does not. The nature of this second factor is discussed. Frame rotation appeared to subtract from object rotation when the two were being compared; this could explain a paradox in picture perception: Depicted orientations often seem little changed over viewpoints, despite (apparent) rotations with respect to real-space coordinates.     

Spatial Reversal as a Measure of Executive Functioning in Children With Autism

The purpose of this experiment was to compare the executive functioning performance of children with autism with chronological- and verbal-matched controls in a spatial-reversal task. Three groups of children participated in this experiment. One group was identified as having autism (7 boys), the 2nd group contained 7 typically developing children (6 boys, 1 girl) who were matched to the 1st group based on their verbal performance, and the 3rd group contained 7 typically functioning children (6 boys, 1 girl) matched to the 1st group based on chronological age. Each group was given a spatial-reversal task containing 2 problems. In the 1st problem, children selected a toy on a particular side in a pair. In the 2nd problem, the contingencies were reversed such that children were to choose the toy on the opposite side. Children with autism generally performed worse than comparison groups as indicated by their overall higher rate of errors. However, these results must be qualified by considering the performance for each problem: Errors for the children with autism were infrequent during the 1st problem but increased in the 2nd, whereas errors for comparison children showed the opposite pattern. When these results from the spatial-reversal task were intérpreted from the perspective of hypothesis-testing theory, the executive functioning deficiency of children with autism was found to involve the selection and testing of stereotypic response sets that were not likely to be revised or changed flexibly according to feedback from the environment or the demands of the task.     

Exploring Psychological Reactions to Injury in the Australian Football League (AFL)

This study explored Australian rules footballers’ psychological responses to injury. This exploratory study was the first in a series of studies planned to examine the injury-related experiences of professional Australian football players. Forty-three professional AFL players from the one team participated in semi-structured interviews. Results provided a detailed account recalled by AFL footballers of their past injury experiences. Specifically, AFL players discussed their initial emotional reactions to injury, which were dependant on the severity of the injury, the extent of isolation during injury, the repetitive nature of the rehabilitation process, and the influence of social support on their reactions.     

Social identity and worldview validation: the effects of ingroup identity primes and mortality salience on value endorsement

In this article, the authors report an investigation of the relationship between terror management and social identity processes by testing for the effects of social identity salience on worldview validation. Two studies, with distinct populations, were conducted to test the hypothesis that mortality salience would lead to worldview validation of values related to a salient social identity. In Study 1, reasonable support for this hypothesis was found with bicultural Aboriginal Australian participants (N = 97). It was found that thoughts of death led participants to validate ingroup and reject outgroup values depending on the social identity that had been made salient. In Study 2, when their student and Australian identities were primed, respectively, Anglo-Australian students (N = 119) validated values related to those identities, exclusively. The implications of the findings for identity-based worldview validation are discussed.     

Attitudes Toward Gay Men and Lesbians Among Heterosexual Male and Female Student-Athletes

The purpose of this study was to explore attitudes toward lesbians and gay men among 371 heterosexual male and female collegiate student-athletes in the USA. Attitudes were assessed in relationship to the student-athletes’ gender, sport and contact. Participants completed a demographic form and the Attitudes toward Lesbians and Gay Men (ATLG-S) Scale (Herek in Journal of Homosexuality 10:39–51, 1984, Journal of Sex Research 25:451–477, 1988). Male student-athletes were significantly more negative in their attitudes toward gay men and lesbians than females. With the exception of field hockey, there were no significant differences in the attitudes toward gay men and lesbians for student-athletes competing on different sport teams. Lastly, student-athletes that indicated having contact with gay men and/or lesbians had significantly more positive attitudes toward gay men and lesbians.     

Indigenous reconciliation in Australia: do values,identity and collective guilt matter?

This paper reports an investigation of the impact of shared values and identities on Australian attitudes towards Indigenous reconciliation across two studies. In Study 1, University students were assigned to one of two conditions in which they completed a questionnaire that measured their value priorities and reconciliation attitudes; either as an individual or as an Australian. As expected, the value of egalitarianism was the strongest predictor of reconciliation attitudes, especially under the Australian condition. In Study 2, participants from the general community were assigned into conditions that manipulated identity (personal vs. Australian) and views of how Indigenous Australians have been treated by Europeans in the past (favourable vs. unfavourable). Under these conditions, participants were asked to report their level of collective guilt and reconciliation views. The results showed that collective guilt was stronger under the unfavourable than the favourable history condition but only when personal identity was salient. The findings also showed some support for the proposition that reconciliation views would be most positive under the unfavourable history condition when Australian identity was salient. The implications of the findings for advancing the progress of indigenous reconciliation in Australia are discussed. Copyright © 2006 John Wiley & Sons, Ltd.
