Intractability and the use of heuristics in psychological explanations

Many cognitive scientists, having discovered that some computational-level characterization f of a cognitive capacity ${\phi}$ is intractable, invoke heuristics as algorithmic-level explanations of how cognizers compute f. We argue that such explanations are actually dysfunctional, and rebut five possible objections. We then propose computational-level theory revision as a principled and workable alternative.     

The pursuit of happiness can be lonely

Few things seem more natural and functional than wanting to be happy. We suggest that, counter to this intuition, valuing happiness may have some surprising negative consequences. Specifically, because striving for personal gains can damage connections with others and because happiness is usually defined in terms of personal positive feelings (a personal gain) in western contexts, striving for happiness might damage people's connections with others and make them lonely. In 2 studies, we provide support for this hypothesis. Study 1 suggests that the more people value happiness, the lonelier they feel on a daily basis (assessed over 2 weeks with diaries). Study 2 provides an experimental manipulation of valuing happiness and demonstrates that inducing people to value happiness leads to relatively greater loneliness, as measured by self-reports and a hormonal index (progesterone). In each study, key potential confounds, such as positive and negative affect, were ruled out. These findings suggest that wanting to be happy can make people lonely.

Engaged at Work and Happy at Home: A Spillover–Crossover Model

The current diary study among 50 Spanish dual-earner couples examines whether engagement at work has an impact on own and partners’ well-being. Based on the Spillover–Crossover model, we hypothesized that individuals’ work engagement would spill over to the home domain, increasing their happiness level at the end of the day. Moreover, we predicted a crossover of happiness between the members of the couple. Participants filled in a diary booklet during five consecutive working days (N = 100 participants and N = 500 occasions). The results of multilevel analyses showed that daily work engagement has a direct effect on daily happiness. We also found that employees’ daily work engagement influenced partner’s daily happiness through employees’ daily happiness. Finally, results showed a clear bidirectional crossover of daily happiness between both members of the couple. These findings indicate that the positive effects of work engagement go beyond the work setting and beyond the employee.     

Pleasure,Arousal, Dominance: Mehrabian and Russell revisited

This paper presents a discursive review of the dimensions pleasure, arousal and dominance that Mehrabian and Russell developed in 1974 to assess environmental perception, experience, and psychological responses. Since then numerous researchers applied these dimensions to assess the experience of the physical environment and its perceived qualities. Although the dimensions appeared to be useful, there is a long-lasting debate going on among environmental psychologists about the interpretation of pleasure, arousal and dominance and its underlying mechanisms. Due to the lack of clarity researchers use different adjectives to describe environmental experiences, which makes any comparison between research findings difficult. This paper shows that the three dimensions can be linked to the current ABC Model of Attitudes: pleasure, arousal and dominance can be respectively related to affective, cognitive and conative responses, i.e. Affect, Cognition and Behaviour (ABC). In addition, connecting the three dimensions to the triad feeling, thinking and acting, can also help to improve our understanding, interpretation and measurement of pleasure, arousal and dominance. Based on this review, it is proposed to re-introduce the three dimensions and to replace the nowadays often used two dimensional model with pleasure and arousal by a three dimensional model, including dominance as a third dimension, to represent the complete range of human responses.     

Genetic Counseling Practice in Next Generation Sequencing Research: Implications for the Ethical Oversight of the Informed Consent Process

The potential for next generation sequencing research (NGS) to generate individual genetic results could have implications for the informed consent process and the provision of genetic counseling. We undertook a content analysis of informed consent templates and guidelines produced by Canadian institutional review boards, purposively sampling documents used by researchers to obtain consent from participants in genetics studies. Our goal was to examine the extent to which the informed consent documents addressed genetic counseling and the return of individual genetic results. Our analysis reveals that the majority of informed consent documents did not mention genetic counseling while several did not mention the return of results. We found differences in the ways in which documents addressed availability of counseling, eligibility criteria for referral to a genetic counselor, genetic counselor involvement, provision of services to family members of participants and incidental findings. From an ethical standpoint, consent documents should provide appropriate information so that participants may make an informed decision about their participation in research. The need to ensure adequate counseling for study populations in an NGS research context will necessarily involve adapting values that underlie care in genetic counseling practice. If the interests of research participants are to be truly promoted, the drafting and review of informed consent documents should give proper due to genetic counseling.     

Recovery at home and performance at work: A diary study on self–family facilitation

This 5-day diary study among 65 Dutch employees focuses on the interplay between time on and off the job. We examined how daily off-job (work-related, physical, household) activities, in combination with the degree to which people want to engage in these activities relate to self–family facilitation (i.e., the positive influence of the fulfilment of one's own interests on one's family life). Further, we tested whether self–family facilitation relates to psychological detachment from work, recovery, and finally whether recovery relates to job performance. Multilevel analyses revealed that household activities enhance self–family facilitation only on days that people want to engage in such activities. Furthermore, spending time on household activities hinders psychological detachment on days people do not want to spend time on these activities. In addition, self–family facilitation and psychological detachment relate to better recovery the next morning. Finally, feeling recovered in the morning is beneficial for task performance during work. These findings emphasize the role of one's “wants” in the degree to which off-job activities lead to recovery. Furthermore, the results highlight the importance of keeping a good interaction between the self and the family for daily recovery and performance.     

The added value of the positive: A literature review of positive psychology interventions in organizations

This paper systematically reviews research investigating the effects of positive psychology interventions applied in the organizational context. We characterize a positive psychology intervention as any intentional activity or method that is based on (a) the cultivation of positive subjective experiences, (b) the building of positive individual traits, or (c) the building of civic virtue and positive institutions. A systematic literature search identified 15 studies that examined the effects of such an intervention in organizational contexts. Subsequent analyses of those studies revealed that positive psychology interventions seem to be a promising tool for enhancing employee well-being and performance. As a side-effect, positive psychology interventions also tend to diminish stress and burnout and to a lesser extent depression and anxiety. Implications of those findings for theory and praxis and recommendations for future research on positive psychology interventions in organizations are discussed.
