The role of self‐esteem and anxiety in decision making for self versus others in relationships

Previous research has documented a tendency for people to make more risk‐seeking decisions for others than for themselves in relationship scenarios. Two experiments investigated whether this self–other difference is moderated by participants' self‐esteem and anxiety levels. In Experiment 1, lower self‐esteem and higher anxiety levels were associated with more risk‐averse choices for personal decisions but not for decisions for others. Therefore, participants with lower self‐esteem/higher anxiety showed greater self–other differences in comparison to participants with higher self‐esteem/lower anxiety levels. Experiment 2 demonstrated that this effect was largely mediated by participants' expectations of success and feelings about potential negative outcomes. These results are discussed in the context of “threats to the self,” with a central role played by anxiety and self‐esteem threats in personal decision making but not in decision making for others.

Identity styles and causality orientations: in search of the motivational underpinnings of the identity exploration process

This study examines relationships between constructs based on two perspectives on the development of self‐governance, namely Self‐Determination Theory (SDT; Deci & Ryan, 2000) and Berzonsky's (1990) identity style model. Theoretically predictable relationships are found between the three causality orientations defined by SDT (autonomous, controlled, and impersonal) and the three identity styles proposed by Berzonsky (informational, normative, diffuse–avoidant) in a sample of Belgian late adolescents. An autonomous causality orientation is positively related to an informational identity style and negatively related to a diffuse–avoidant style. A controlled orientation is positively associated with a normative identity style, and an impersonal orientation is positively related to a diffuse–avoidant identity style. Participants' gender does not moderate these relationships. The findings suggest that the causality orientations late adolescents employ may play an important role in how actively and thoroughly they explore identity‐relevant issues.

Behavioral profile of L‐655,708, a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit,in social encounters between male mice

GABA‐A receptor is a transmembrane hetero‐oligomeric protein which consists of five subunits, the combination of which confers unique pharmacological properties to the receptor. It is well‐known that the GABAergic system is involved in the modulation of aggression. However, the role of α5/GABA‐A receptors has not been explored. In this study, we examined the effect of L‐655,708 (0.625‐5 mg/kg), a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit, on agonistic behavior elicited by isolation in male mice. Individually housed mice were exposed to an anosmic “standard opponent” 30 min after drug administration, and the encounters were videotaped and evaluated using an ethologically based analysis. L‐655,708 (5 mg/kg) exhibited an ethopharmacological profile characterized by a marked reduction of the time spent in offensive behavior (threat and attack) without affecting immobility, accompanied by a significant increase of avoidance/flee and nonsocial exploration behaviors, suggesting that the antiaggressive effect of the drug is unselective. Overall, this behavioral profile might indicate the existence of an anxiogenic‐like activity of L‐655,708 in mice. Aggr. Behav. 30:319–325, 2004. © 2004 Wiley‐Liss, Inc.     

Small wonders of the Indian market

Heavy competition in India in almost all product categories, due to diversification by large and medium companies and increased entry of multinationals, has restricted the growth of domestic companies. Previously, large companies enjoyed high profit margins by targeting premium priced products in the upper strata of Indian society. High levels of competition from equally reputed brands have not only decreased the companies' market share but also created price wars, reducing profit margins and limiting market growth. This has motivated companies to consider the lower classes and the rural segments, which they had previously ignored. By targeting these segments with products in small packs at lower price points, companies have experienced great success. At the same time, small packs also pose some challenges for the companies. This paper explains the importance of small packs for market expansion in various product categories within the Indian market, drawing on several examples to support the views of the authors.

Symbolic consumption in teenagers' clothing choices

The importance of the symbolic properties of goods has been explored in depth among adult consumers, but there has been less attention given to the symbolic consumption of young people. This study explores the subject of symbolic consumption with specific reference to clothing in the teenage market. Thirty‐eight young people were interviewed, and age, sex and social position variations were considered. The results of this study suggest that conspicuous consumption is relevant for young people, and that they are a group which is adept at reading the signals represented in clothing choices. The authors found that the clothes choices made by young people are closely bound to their self‐concept, and are used both as a means of self‐expression and as a way of judging the people and situations they face. Evidence was also found that clothing has a function in role fulfilment, making the wearer more confident and capable. Overall, clothing can be viewed as an essential social tool in the lives of teenagers. Copyright © 2004 Henry Stewart Publications Ltd.     

Visuo‐spatial play experience: forerunner of visuo‐spatial achievement in preadolescent and adolescent boys and girls?

This cross‐sectional study explored whether participation, from early childhood, in play involving different cognitive abilities predicts visuo‐spatial achievement at ages 9, 12, and 15. Based on parental assessment, prior and present practice of spatial manipulation play was found to be consistently more frequent in boys than in girls; the reverse held true for verbal expression play. Whereas boys did not significantly outperform girls in three visuo‐spatial tasks, girls were superior on a contrastive vocabulary task. In general, with IQ statistically controlled, regression analyses showed that estimated past and present spatial manipulation play predicted both genders' proficiency in the water‐level task and Embedded Figures Test, as did mothers' socioeconomic status for Block Design performance. Contrastingly, a negative relation was established between spatial manipulation play and vocabulary scores. Similar to the activity‐ability association often identified among adults, the relation established here between spatial play experience and visuo‐spatial ability was only modest. Further research should aim at more definitive conclusions through augmenting both diversity in the visuo‐spatial skills measured and sophistication in play behaviour appraisal.

Features and investigative implications of muti murder in South Africa

Drawing upon anthropological, legal and forensic publications, an interview with a South African Zulu traditional healer and direct information gained during homicide investigations, the nature of Muti murder is discussed. Muti murder is defined as a murder in which body parts are removed from a live victim for the sole purpose of using the victim's body parts medicinally. These body parts are then often mixed with other ingredients or used alone to make a medicine called muti. Muti is a Zulu (umuthi) word meaning medicine. The victim usually dies as a result of blood loss from the wounds. While muti murders have occurred throughout history in South African culture, little is known about them and little research exists on the phenomenon. The term muti murder has been used interchangeably with the term ritual or sacrificial murder, often adding to confusion in terminology and definitions regarding these types of cases. This paper provides an overview of muti murder, explains the context in which these types of murder occur, defines the offenders and victims involved, and provides guidelines for investigating these types of murders. Two cases where muti murder was suspected are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Self‐regulation and well‐being: The influence of identity and motives

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd.     

Stop and start control: A distinction within self‐control

A theoretical distinction within self‐control, between stop control and start control, was investigated in two studies. Study 1 consisted of a pilot study in which expert ratings of existing self‐control items were used to distinguish between stop and start control items and a confirmatory factor analyses of these items using a student sample (N = 474). Also, stop and start control were related to overall affect and behavioural outcomes. Stop control was negatively related to negative affect, whereas start control was positively related to positive affect. Study 2 (N = 226) replicated some of these findings; stop control was the best predictor (?) of smoking and alcohol consumption whereas start control was the best predictor (+) of exercising and studying.
