The Role of Social Presence in Interactive Agent-Based Persuasion

This investigation examines the extent to which interactive social agent technology can influence social presence, information processing, and persuasion. Specifically, it looks at how interactive media using virtual agents can increase the sensation of social presence, or the extent to which a person feels “with” a mediated being. Using logic based on the Heuristic Systematic Model (HSM), social presence is posited to impact indicators of heuristic and systematic processing, leading to changes in attitude and intention toward a health issue. A 2 × 2 between subjects experiment was conducted (N = 125) with manipulations of interactivity (interactive or not) and source attractiveness (attractive or unattractive). Results of causal model tests suggest that interactive agents facilitate social presence leading to increased message processing, which in turn affects both attitude and behavioral intentions toward the issue of healthy blood pressure. Contrary to expectations, however, social presence with an unattractive source did not impede attitude and intentions. These findings are interpreted in light of presence, new media, and HSM scholarship.     

Moderators of the association between exercise identity and obligatory exercise among participants of an athletic event

Previous research has connected exercise identity with obligatory exercise, yet to date no empirical studies have identified moderator variables of this association. The current study included participants of an athletic event (full marathon, n = 582; half marathon, n = 1,106; shorter distance, n = 733) who completed questionnaires about exercise behaviors, obligatory exercise, and internalization of both the thin-ideal and athletic-ideal body shapes. General linear model analyses were conducted to examine the exercise identity–obligatory exercise relationship; moderator variables included gender, internalization of the thin-ideal body shape, and internalization of the athletic-ideal body shape. After controlling for the effects of body mass index, age, and distance group, the three-way interaction of exercise identity, gender, and internalization of the athletic-ideal body shape predicted obligatory exercise. Findings suggest that women who report high identification with exercise and high value on having an athletic physique may be vulnerable to obligatory exercise.     

The epistemological status of a naturalized epistemology

Philosophically inclined psychologists and psychologically inclined philosophers often hold that the substantive discoveries of psychology can provide an empirical foundation for epistemology. In this paper it is argued that the ambition to found epistemology empirically faces certain unnoticed difficulties. Empirical theories concerned with knowledge‐gaining abilities have been historically associated with specific epistemological views such that the epistemology gives preferential support to the substantive theory, while the theory empirically supports the epistemology. Theories attribute to the subject just those epistemic abilities which associated epistemologies attribute to the scientist. The concept of epistemological significance is introduced as the significance a psychological theory can have for modifying the epistemological suppositions with which the theory was originally associated. Substantive psychological theories are strongly constrained by the epistemologies used in their development; the endorsement an epistemology receives from its associated theory should carry no weight. The alliance between psychology and epistemology is not progressive to the development of either field. Alternative sources of progress in epistemology and psychology are suggested.     

The effects of smoking norms and attitudes on quitting intentions in Malaysia,Thailand and four Western nations: A cross-cultural comparison

This research investigated the influence of smoking attitudes and norms on quitting intentions in two predominantly collectivistic countries (Malaysia and Thailand) and four predominantly individualistic Western countries (Canada, USA, UK and Australia). Data from the International Tobacco Control Project (N = 13,062) revealed that higher odds of intending to quit were associated with negative personal attitudes in Thailand and the Western countries, but not in Malaysia; with norms against smoking from significant others in Malaysia and the Western countries, but not in Thailand; and with societal norms against smoking in all countries. Our findings indicate that normative factors are important determinants of intentions, but they play a different role in different cultural and/or tobacco control contexts. Interventions may be more effective if they are designed with these different patterns of social influence in mind.     

Predictors of distress following an acute stroke: Disability,control cognitions,and satisfaction with care

Abstract

Whilst clinical predictors of distress following acute stroke have been identified (e.g., lesion site), this study hypothesised that greater prediction would be achieved by addressing individual differences in patients' cognitions (e.g., perceived control, satisfaction with care, recovery confidence) and coping responses. We examined these relationships in a longitudinal study of 71 survivors of acute stroke. Measures were collected at three time points: 10-20 days after the stroke, and one month and six months after hospital discharge. Stepwise multiple regression analyses were performed using only significant bivariate correlates and where the dependent variables were residualised scores which controlled for baseline levels of anxiety and depression. Satisfaction with treatment and confidence in recovery at one month predicted anxiety outcome at six months, and satisfaction with advice and confidence in recovery at one month predicted depression outcome at six months. These results offer tentative suggestions for interventions targeting patient cognitions and improving patient satisfaction.     

Characteristics of exiled smoking from workplaces

Abstract

This paper explores factors influencing the extent of exiled smoking from workplaces: that is leaving work so as to smoke a cigarette. Exiled smoking may be disruptive to work practices and it is a means by which smokers minimise the effects of workplace smoking bans on their daily consumption. As such it reduces possible health benefits that might have resulted from a greater decrease in consumption. Smokers (n = 145) were recruited while engaging in exiled smoking. The results indicate that among this group (of largely regular exiled smokers), indices of addiction were only loosely related to the extent of exiled smoking, and it did not appear to be primarily driven by social benefits. While most preferred taking breaks with company, the lack of company would only inhibit a minority. Perceived improvements in capacity to work was a common reason, as was the opportunity to discuss work related problems. Enjoyment of the cigarette and the opportunity to break up the day were also important. It appears exiled smoking is multiply determined. To the extent addiction is involved, it is not through strongly felt urges to smoke, but is more due to minor irritation such as reduced ability to concentrate. It is suggested that such experiences provide the extra motivation to take a break that non-smokers may think about but rarely feel sufficiently motivated to do.     

Testing mediator variables in a resistance training intervention for obese adults with type 2 diabetes

A poor understanding of behaviour change mechanisms has hindered the development of effective physical activity interventions. The aim of this study was to identify potential mediators of change in a home-based resistance training (RT) program for obese individuals with type 2 diabetes. Obese individuals with type 2 diabetes (N?=?48) were randomly allocated to either an RT intervention (n?=?27) or a control group (n?=?21) for the 16-week study period. The study sample included 16 men and 32 women and the mean age of participants was 54.4 (±11.7) years. Participants in the RT group received a multi-gym and dumbbells and home supervision from a certified personal trainer. RT behaviour was measured using a modified Godin Leisure Time Questionnaire. Social-cognitive constructs were measured and tested in a mediating variable framework using a product-of-coefficients test. The intervention had a significant effect on RT behaviour (p?<?0.001) and muscular strength (p?<?0.001). The intervention had a significant effect on RT planning strategies (p?<?0.01), which mediated the effect of the intervention on RT behaviour. The home-based RT program successfully targeted participants’ RT planning strategies which contributed to their exercise adherence.     

Low Self-Esteem as a Risk Factor for Loneliness in Adolescence: Perceived - but not Actual - Social Acceptance as an Underlying Mechanism

Low self-esteem has been shown to relate to concurrent and later feelings of loneliness in adolescence. However, it remains unclear why low self-esteem puts adolescents at risk for experiencing loneliness. Further, longitudinal research on the direction of effects between loneliness and self-esteem is virtually non-existent. The present study aims to fill these gaps in the literature. First, the direction of effects between loneliness and self-esteem was investigated in two independent longitudinal studies: a five-wave study sampling Dutch adolescents (M age?=?15.22 years at T1; 47 % female; N?=?428) and a three-wave study sampling Belgian adolescents (M age?=?14.95 years at T1; 63 % female; N?=?882). Second, the underlying role of social acceptance was investigated in the latter sample by applying a multi-method approach that included actual (i.e., peer-reported) and perceived (i.e., self-reported) social acceptance. Results indicated that self-esteem and loneliness influenced one another in a reciprocal manner. Furthermore, the dominant path from self-esteem to loneliness was partially mediated by perceived—but not actual—social acceptance. The importance of distinguishing actual from perceived social acceptance is discussed, and suggestions for future research are outlined.     

Explicit- and Implicit Bullying Attitudes in Relation to Bullying Behavior

The main aim of this study was to examine whether an assessment of implicit bullying attitudes could add to the prediction of bullying behavior after controlling for explicit bullying attitudes. Primary school children (112 boys and 125 girls, M age = 11 years, 5 months) completed two newly developed measures of implicit bullying attitudes (a general Implicit Association Test on bullying and a movie-primed specific IAT on bullying), an explicit bullying attitude measure, and self reported, peer reported, and teacher rated bullying behavior. While explicit bullying attitudes predicted bullying behavior, implicit attitudes did not. However, a significant interaction between implicit and explicit bullying attitudes indicated that in children with relatively positive explicit attitudes, implicit bullying attitudes were important predictors of bullying behavior. Theoretical and practical implications are discussed.
