AMICAI: A Method Based on Risk Analysis to Integrate Responsible Research and Innovation into the Work of Research and Innovation Practitioners

Science and Engineering Ethics - The integration of ethics into the day-to-day work of research and innovation (R&I) is an important but difficult challenge. However, with the Aachen method...     

Gender differences in online and offline self‐disclosure in pre‐adolescence and adolescence

Although there is developmental research on the prevalence of offline self‐disclosure in pre‐adolescence and adolescence, it is still unknown (a) how boys’ and girls’online self‐disclosure develops in this period and (b) how online and offline self‐disclosure interact with each other. We formulated three hypotheses to explain the possible interaction between online and offline self‐disclosure: the displacement, the rich‐get‐richer, and the rehearsal hypothesis. We surveyed 690 pre‐adolescents and adolescents (10–17 years) at three time points with half‐year intervals in between. We found significant gender differences in the developmental trajectories of self‐disclosure. For girls, both online and offline self‐disclosure increased sharply during pre‐ (10–11 years) and early adolescence (12–13 years), and then stabilized in middle and late adolescence. For boys, the same trajectory was found although the increase in self‐disclosure started 2 years later. We found most support for the rehearsal hypothesis: Both boys and girls seemed to use online self‐disclosure to rehearse offline self‐disclosure skills. This particularly held for boys in early adolescence who typically have difficulty disclosing themselves offline.     

Friend networking sites and their relationship to adolescents' well-being and social self-esteem.

The aim of this study was to investigate the consequences of friend networking sites (e.g., Friendster, MySpace) for adolescents' self-esteem and well-being. We conducted a survey among 881 adolescents (10-19-year-olds) who had an online profile on a Dutch friend networking site. Using structural equation modeling, we found that the frequency with which adolescents used the site had an indirect effect on their social self-esteem and well-being. The use of the friend networking site stimulated the number of relationships formed on the site, the frequency with which adolescents received feedback on their profiles, and the tone (i.e., positive vs. negative) of this feedback. Positive feedback on the profiles enhanced adolescents' social self-esteem and well-being, whereas negative feedback decreased their self-esteem and well-being.     

Defensive self-esteem impacts attention, attitude strength, and self-affirmation processes

Individuals with defensive self-esteem score low on implicit measures of self-esteem (ISE) and high on explicit measures of self-esteem (ESE). Although there is some evidence about the consequences of defensive self-esteem, much of it is indirect and open to alternative explanations. Here, we offer direct and novel evidence regarding the implications of defensive self-esteem. Using a standard visual attention paradigm, Study 1 revealed that defensive self-esteem is associated with enhanced attention to defensiveness-related words. Building upon these results, Study 2 found that defensive self-esteem individuals reported particularly strong attitudes, across different operationalizations of attitude strength as well as different attitude objects. Study 3 examined the sensitivity of defensive self-esteem individuals to self-affirmation effects. The results revealed that self-affirmation was particularly effective for defensive self-esteem individuals in reducing actual-ideal self-discrepancies. Overall, the results provide novel and firm evidence that the combination of simultaneously low ISE and high ESE elicits defensiveness.     

A flexible latent trait model for response times in tests

Latent trait models for response times in tests have become popular recently. One challenge for response time modeling is the fact that the distribution of response times can differ considerably even in similar tests. In order to reduce the need for tailor-made models, a model is proposed that unifies two popular approaches to response time modeling: Proportional hazard models and the accelerated failure time model with log–normally distributed response times. This is accomplished by resorting to discrete time. The categorization of response time allows the formulation of a response time model within the framework of generalized linear models by using a flexible link function. Item parameters of the proposed model can be estimated with marginal maximum likelihood estimation. Applicability of the proposed approach is demonstrated with a simulation study and an empirical application. Additionally, means for the evaluation of model fit are suggested.     

The structure of affective action representations: temporal binding of affective response codes

Two experiments examined the hypothesis that preparing an action with a specific affective connotation involves the binding of this action to an affective code reflecting this connotation. This integration into an action plan should lead to a temporary occupation of the affective code, which should impair the concurrent representation of affectively congruent events, such as the planning of another action with the same valence. This hypothesis was tested with a dual-task setup that required a speeded choice between approach- and avoidance-type lever movements after having planned and before having executed an evaluative button press. In line with the code-occupation hypothesis, slower lever movements were observed when the lever movement was affectively compatible with the prepared evaluative button press than when the two actions were affectively incompatible. Lever movements related to approach and avoidance and evaluative button presses thus seem to share a code that represents affective meaning. A model of affective action control that is based on the theory of event coding is discussed.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60-95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.     

Impersonal Sex Orientation and Multitasking Influence the Effect of Sexual Media Content on Involvement With a Sexual Character

The aim of the present study was to investigate whether responses to sexual media content depend on personal and situational factors. Specifically, we studied the role of the personal factor impersonal sex orientation (IS) and the situational factor multitasking in the effect of sexual media content on involvement with the character, a concept that has received increasing attention as an explanation of sexual media effects. College-aged women who were low or high in IS watched a neutral scene or a sex scene. Half of the participants in the neutral and sex condition had to multitask (a tone detection task) while viewing the scene. In the sex condition, participants high in IS were more involved with the character than participants low in IS. Multitasking resulted in opposite patterns of involvement with the character in the sex condition: Participants high in IS became less involved with the character, whereas participants low in IS became more involved with the character.
