Nice or Naughty? The Role of Emotions and Digital Media Use in Explaining Adolescents’ Online Prosocial and Antisocial Behavior

The opportunities and mostly the risks of digital communication technologies for adolescents have been documented extensively in the last two decades, but less is known about how adolescents interact with each other online, especially regarding positive interactions. Moreover, since online prosocial and antisocial behavior have rarely been assessed simultaneously, it is hard to obtain a balanced view of adolescents’ online behavior. Therefore, in this study, we examined both dimensions of online social behavior and how these are related to adolescents’ experienced emotions and their uses of digital media. Findings indicated that participants performed and received more prosocial than antisocial behavior online. Experiencing negative as well as positive emotions was related to online social behavior, and these associations were mediated by adolescents’ use of social and audiovisual media, but not by gaming or functional Internet use. The social sharing of emotions and mood management theory are used to discuss the results.     

Factor structure of the Norwegian version of the WAIS-III in a clinical sample: the arithmetic problem

Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of factors and in the placement of the Arithmetic subtest in a mixed clinical sample (n = 272). Only the four-factor solutions had adequate goodness-of-fit values. Allowing Arithmetic to load on both the Verbal Comprehension and Working Memory factors provided a more parsimonious solution compared to considering the subtest only as a measure of Working Memory. Effects of education were particularly high for both the Verbal Comprehension tests and Arithmetic.     

Musiktherapie in der Psychosomatik

It is a long way to the formal recognition of a so-called non-verbal mode of therapy that was long considered only as an additional intervention in complex forms of treatment. A historical overview of the development of music therapy in German psychosomatic medicine is followed by a detailed report of the diversities of present techniques in music therapy. Outcome research shows music therapy to be a richer and more diversified method than one would suppose. On this basis specific indications for the implementation of music therapy in medical settings are identifiable.     

Transitioning between temporary and permanent employment: A two‐wave study on the entrapment,the stepping stone and the selection hypothesis

The present two‐wave study investigates how transitioning between temporary and permanent employment relates to a number of psychological consequences; namely, work engagement, affective organizational commitment, life satisfaction, and turnover intention. We hypothesize that temporary employment associates with unfavourable outcomes when it is a trap (entrapment hypothesis), while no such unfavourable outcomes are expected for those who transition to permanent employment (stepping stone hypothesis). Furthermore, we investigate the assumption that transitioning from permanent to temporary employment relates to unfavourable outcomes. Finally, we investigate dynamics related to selection into temporary or permanent employment. Hypotheses are tested on a sample of 1,475 workers. The results show that continuous temporary employment does not relate to unfavourable outcomes over time, while gaining permanent employment associates with increased work engagement. Also, permanent workers who transition to temporary employment are more engaged and committed after transitioning. No evidence for possible selection mechanisms is found.     

Social comparison with friends versus non‐friends

This paper investigates whether several aspects of social comparison in school classes differ as a function of the type of relation between the student and his or her target. Participants were 9612 students in the first grade of secondary education in the Netherlands (equivalent to Grade 7 in the US). Results indicated that (1) 78% of the students who had at least one friend also compared with a friend; (2) social comparison with friends was much more often reciprocal than comparison with non‐friends; (3) preferences for upward and downward comparison were less often given by students who compared with friends than students who compared with non‐friends; (4) the similarity in initial performance level between students and their comparison targets was higher when targets were friends; (5) despite these differences, which seem to imply that friends often serve as routine standards whereas non‐friends are more deliberately chosen as comparison targets, it appeared that consequences of social comparison for subsequent performance were about the same for both types of relations. Further findings of this paper suggest that previously found effects of friends' grades on subsequent performance may be explained by social comparison. Copyright © 2007 John Wiley & Sons, Ltd.     

Integrating commons dilemma findings in a general dynamic model of cooperative behavior in resource crises

The research on commons dilemmas is characterized by innumerable published findings, each standing relatively isolated from the other. To date there is little integration of the findings under a unified concept. The present contribution aims to integrate already existing findings in a general dynamic model of cooperative behavior in resource crises by means of computer simulation. The model postulates that people base their decisions regarding resource use on both ecological and social information. Whether or not ecological or social information will dominate, however, depends on people's social values, attributions, and their perceptions of the state of the resource. The advantage of the simulation method used is that successful integration of the findings can be shown explicitly, as the simulation then replicates the experimental data. With the model presented here, it is also possible to let variables work together whose interaction has not yet been investigated in real experiments. For instance, the simulation model allows us to hypothesize that people, in dependency upon their resource uncertainty and in dependency upon their attributions, utilize a resource completely differently if the resource is in an optimal or sub‐optimal condition.

The Role of Consumption Emotions in the Satisfaction Response

We report 2 studies that served to clarify the role of consumption emotions in the satisfaction response. In the 1st study, we examined the role of consumption emotions within the expectancy‐disconfirmation model of consumer satisfaction and investigated whether consumption emotions are a result of product performance or disconfirmation. The findings show that both positive and negative emotions are primarily a function of product performance and influence satisfaction even when the effects of expectations, performance, and disconfirmation are controlled. In the 2nd study, we proposed and tested an alternative framework for understanding the role of consumption emotions in the satisfaction response for situations in which consumers use more of an experiential perspective to anticipate and experience consumption. According to this model, consumers form affective expectations about how consumption of the product will make them feel, experience positive or negative emotions as a result of these expectations and product consumption, and evaluate the discrepancy between experienced and anticipated emotions. All 3 variables, then, impact satisfaction. The results empirically support many of the relations in the new model of the experiential satisfaction response but also raise several interesting avenues for future research.
