Emoticons and Online Message Interpretation

The present study experimentally examines the impact of emoticons on message interpretation among secondary school students (N = 105). Furthermore, perceived motives for emoticon use are examined. Results show that emoticons do have an impact on message interpretation. Emoticons are useful in strengthening the intensity of a verbal message. Furthermore, it is possible to create ambiguity and express sarcasm online by varying the valence of the emoticon and the valence of the message. Overall, the authors conclude that to a large extent, emoticons serve the same functions as actual nonverbal behavior.

Reducing AIDS-related stigma in developing countries : The importance of theory-and evidence-based interventions

In many developing countries persons living with HIV and AIDS experience strong stigma and discrimination, and AIDS-related stigma has an enormous negative impact on their social relationships, access to resources, and psychological well being. Moreover, AIDS-related stigma hampers HIV-related health promotion, including voluntary HIV counselling and testing. In this article, we will argue that programs to reduce AIDS-related stigma are most likely to be effective if these programs are based upon thorough needs assessments, theory- and evidence-based intervention strategies and collaborative planning. A protocol for health promotion programs design is outlined. Furthermore, psychosocial correlates of AIDS-related stigma in developing countries, social-psychological theories that might be useful in designing intervention strategies to reduce stigmatisation and successful elements of previous interventions aimed at stigma reduction are discussed. It is concluded that psychological theory does provide guidelines for the development of stigma-reducing intervention programs, but that such programs can only be effective when based upon context-specific needs assessment and collaborative planning.

Self-Sacrificial Leadership and Follower Self-Esteem: When Collective Identification Matters

In the present research, we examine whether leader’s self-sacrifice positively influences followers’ self-esteem and whether followers’ identification with the collective plays a role in this process. It was predicted that leader self-sacrifice would influence followers’ self-esteem, but particularly so when followers exhibited strong (vs. weak) collective identification. Results from an organizational survey showed that leader self-sacrifice and collective identification interacted in predicting follower self-esteem, such that followers’ self-esteem was higher when they identified strongly with the collective and when the leader was self-sacrificial (vs. self-benefiting). An experimental scenario study replicated this interactive effect between collective identification and leader’s self-sacrifice on followers’ self-esteem and also showed that this effect was (at least partly) mediated by followers’ perceptions of whether the leader respected and valued the group. Implications with respect to the relationship between self-sacrifice and self-esteem are outlined, and possible integrations of leader self-sacrifice, identity, and empowerment are discussed.

Sex differences in emotional and behavioral responses to HIV+ individuals' expression of distress

Two studies examined the influence of HIV+ individuals expression of distress on perceivers’ emotional and behavioral reactions. In Study 1 (N = 224), HIV+ individuals expression of distress was experimentally manipulated by means of vignettes. Men and women reacted differently when persons with HIV conveyed distress: women reported stronger feelings of pity, whereas men reported stronger feelings of anger. Study 2 (N = 136) replicated this study in a realistic experimental setting with additional behavioral measures. Similarly, women reported stronger pro-social behavior than men when confronted with a person with HIV who conveyed distress. Results of the present study shed additional light to the self-presentational dilemma of ill persons. Conveying moderate levels of distress may evoke pro-social responses in women, but not in men.

Disgust sensitivity and eating disorder symptoms in a non-clinical population

In order to further explore the relationship between disgust sensitivity and eating disorder symptoms, 2 studies were carried out. In the first study, 352 higher education students (166 women, 186 men) completed a set of questionnaires measuring various aspects of disgust sensitivity and eating disorder symptoms. A correlational analysis revealed that there were few significant correlations between disgust scales and eating pathology scores. One exception was the relation between disgust sensitivity and external eating behavior, although this link only emerged in women. To investigate this relationship in more detail, Study 2 confronted women high (n=29) and low (n=30) on external eating behavior with a series of disgusting and neutral pictures. It was hypothesized that women who scored high on external eating would display shorter viewing times of disgusting pictures (i.e., show more avoidance behavior) than women scoring low on external eating. However, this hypothesis was not confirmed by the data. Altogether, the results of these studies suggest that there seems to be no convincing relationship between disgust sensitivity and eating disorder symptomatology, thereby casting doubts on the role of this individual difference factor in the development of eating pathology.

Does disgust enhance eating disorder symptoms

In the present study, the hypothesized causal relationship between disgust and eating pathology was investigated. Female undergraduates were either assigned to an experimental condition in which feelings of disgust were induced by means of a bad smelling odorant, or to a control condition in which no such disgust manipulation was carried out. Both groups completed questionnaires for measuring various eating disorder-related concepts (i.e., body esteem, restraint eating, and body change strategies). In addition, explicit and implicit preferences for high-caloric food were measured. Results demonstrated that women in the experimental condition did not report lower levels of body esteem, and neither showed higher levels of restraint eating or other body change strategies. Furthermore, they did not display a decreased explicit or implicit preference for high-caloric food. Thus, in the present study no indication for a causal relation between disgust and eating disorder symptoms in young females was found.
