A psychological model of social control and stigmatization: evolutionary background and practical implications

The strengths and limitations of three main theoretical approaches to social control and stigmatization are discussed, originating from social psychology, sociology and anthropology, and evolutionary psychology, respectively. A theoretical model is proposed that integrates universal (evolutionary derived) psychological aspects of social control and the great variation that can be observed in responding to deviance within and between cultures and historical periods. Practical implications of the model are discussed.     

Condom use in steady and casual sexual relationships: Planning, preparation and willingness to take risks among adolescents

Condom use within steady and casual sexual relationships was examined among 14-16 year old Dutch adolescents from secondary school (N?=?140). It was hypothesised that among adolescents sex and subsequently condom use with casual sex partners is less likely to be considered in advance, more context-dependent and less habitual; whereas the opposite is true for steady relationships. Therefore, preparatory behaviours (buying and carrying condoms and communicating about condom use) were expected to mediate the intention-behaviour relation in the context of steady relationships, but not in the context of casual sex. Results confirmed that condom use with steady sex partners was explained by preparatory behaviours, habits, and to some extent, behavioural willingness, and that preparatory behaviours mediated the intention-behaviour relationship. Condom use with casual sex partners was predicted by risk willingness and intentions, without any mediation by preparatory behaviours. The results indicate that it is essential to increase awareness among adolescents that unexpected sexual situations may occur and to train them to take preparatory actions.     

Clustering of diet,physical activity and smoking and a general willingness to change

Addressing multiple health behaviours are important in preventing disease and mortality. The present study investigated the clustering of health behaviours, cognitive determinants and stages of change in 2827 adults for the lifestyle factors of physical activity, fruit, vegetable and fat consumption and smoking. The results showed that only 3% of the total population met recommended guidelines for all of the five behaviours. Behaviours were found to be weakly associated. Behaviour-specific cognitions and stages of change for the behaviours clustered more strongly, however. With respect to diet and physical activity, respondents in the preparation stage for one behaviour were likely also to be preparing to change another behaviour. Possible mechanisms for the apparent general willingness to change multiple behaviours are discussed, as well as potential implications for health promotion practice.     

How to turn a hawk into a dove and vice versa: Interactions between emotions and goals in a give-some dilemma game

The present study investigated emotional influences on behavior in a one-shot, simultaneous, give-some dilemma game. In accordance with functional perspectives on the role of discrete emotions, we found fear to reduce, and guilt to increase levels of cooperation. Moreover, we showed individual differences in the effect of induced emotional states. Specifically, results indicated that inducing fear reduced cooperation only for individuals with a pro-social value orientation, and that guilt induction increased cooperation only for individuals with a pro-self value orientation. We also established that both social value orientations could be adequately described in terms of differences in chronically accessible goals (as assessed by value-importance ratings). These results, therefore, seem to support our hypothesis that individual differences in the behavioral consequences of induced emotional states are related to variation in chronic accessibility of general goals associated with a particular emotional state.     

The role of expectancies in the size-weight illusion: A review of theoretical and empirical arguments and a new explanation

The size–weight illusion (SWI) refers to the phenomenon that objects that are objectively equal in weight but different in size or volume are perceived to differ in weight, such that smaller objects feel heavier than larger ones. This article reviews studies trying to support three different viewpoints with respect to the role of expectancies in causing the SWI. The first viewpoint argues for a crucial role; the second admits a role, yet without seeing consequences for sensorimotor processes; and the third denies any causal role for expectancies at all. A new explanation of the SWI is proposed that can integrate the different arguments. A distinctive feature of the new explanation is that it recognizes the causal influence of expectancies, yet combines this with certain reactive and direct behavioral consequences of perceiving size differences that are independent of experience-based expectancies, and that normally result in the adaptive application of forces to lift or handle differently sized objects. The new account explains why the illusion is associated with the repeated generation of inappropriate lifting forces (which can, however, be modified through extensive training), as well as why it depends on continuous visual exposure to size cues, appears at an early age, and is cognitively impenetrable.     

Why Barbie feels heavier than Ken: the influence of size-based expectancies and social cues on the illusory perception of weight

In order to examine the relative influence of size-based expectancies and social cues on the perceived weight of objects, two studies were performed, using equally weighing dolls differing in sex-related and age-related vulnerability or physical strength cues. To increase variation in perceived size, stimulus objects were viewed through optical lenses of varying reducing power. Different groups of participants were required to provide magnitude estimates of perceived size, physical strength, or weight, or of expected weight. A size-weight illusion (SWI) was demonstrated, such that smaller objects felt heavier than larger ones, that was entirely accounted for by the mediating role of expected weight. Yet, perceived physical strength exerted an additional and more reactive influence on perceived weight independently of measured expectancies. Results are used to clarify the nature of "embodied", internal sensory-motor representations of physical and social properties.     

Emotional reactions to ethnic minorities

The present study investigated the role of emotion in the area of intergroup relations. Results showed three ways in which emotions are relevant when Dutch autochthonous people are confronted with members of the three major ethnic minorities in The Netherlands: Surinamers and immigrant workers from Turkey and Morocco. First, four categories of emotions could be identified which appeared to be strongly associated with ethnic attitude-positive mood, anxiety, irritation and concern-each related to a specific kind of action readiness. Second, the influence which proximity of an ethnic group appeared to have on ethnic attitude could be explained by the specific kind of emotional experience related to different levels of proximity. The third way in which emotions appeared to be relevant was their ability to differentiate between the qualitative aspects of various forms of ethnic contact. With Surinamers, more personal forms of contact were associated with an increase in positive mood and a decrease in anxiety, irritation and concern. But for Turks and Moroccans, who can be considered to be in more basic respects culturally dissimilar from the Dutch, only negative aspects of close contact were found. The correspondence of the results with several research findings in the field of intergroup relations, is extensively discussed.     

School programs targeting stress management in children and adolescents: A meta-analysis

Introduction

This meta-analysis evaluates the effect of school programs targeting stress management or coping skills in school children.

Methods

Articles were selected through a systematic literature search. Only randomized controlled trials or quasi-experimental studies were included. The standardized mean differences (SMDs) between baseline and final measures were computed for experimental and control groups. Experimental groups were groups that either received an intervention of (a) relaxation training, (b) social problem solving, (c) social adjustment and emotional self-control, or (d) a combination of these interventions. If no baseline measurement was available, SMDs were calculated between final measures of the groups. The overall pooled effect size was calculated and the pooled effect sizes of improvement on stress, coping, (social) behavior, and self-efficacy by random effects meta-analysis. The dependence of the results on study characteristics (i.e. methodological quality and type of intervention) was evaluated using meta-regression analysis.

Results

Nineteen publications met the inclusion criteria of controlled trials for class programs, teaching coping skills or stress management. Overall effect size for the programs was − 1.51 [95% confidence interval (CI) − 2.29, − 0.73], indicating a positive effect. However, heterogeneity was significant (p < .001). Sensitivity analyses showed that study quality and type of intervention were sources of heterogeneity influencing the overall result (p values < .001). The heterogeneity in quality may be associated with methodological diversity and differences in outcome assessments, rather than variety in treatment effect. Effect was calculated per intervention type, and positive effects were found for stress symptoms with a pooled effect size of − 0.865 (95% CI: − 1.229, − 0.502) and for coping with a pooled effect size of − 3.493 (95% CI: − 6.711, − 0.275).

Conclusion

It is tentatively concluded that school programs targeting stress management or coping skills are effective in reducing stress symptoms and enhancing coping skills. Future research should use clear quality criteria and strive for less diversity in methodology and outcome assessment.
