Social preference in rats

Rats were given repeated choices between social and nonsocial outcomes, and between familiar and unfamiliar social outcomes. Lever presses on either of 2 levers in the middle chamber of a 3-chamber apparatus opened a door adjacent to the lever, permitting 45-s access to social interaction with the rat in the chosen side chamber. In Experiment 1, rats preferred (a) social over nonsocial options, choosing their cagemate rat over an empty chamber, and (b) an unfamiliar over a familiar rat, choosing a non-cagemate over their cagemate. These findings were replicated in Experiment 2 with 2 different non-cagemate rats. Rats preferred both non-cagemate rats to a similar degree when pitted against their cagemate, but were indifferent when the 2 non-cagemates were pitted against each other. Similar preference for social over nonsocial and non-cagemate over cagemate was seen in Experiment 3, with new non-cagemate rats introduced after every third session. Response rates (for both cagemate and non-cagemate rats) were elevated under conditions of nonsocial (isolated) housing compared to conditions of social (paired) housing, demonstrating a social deprivation effect. Together, the experiments contribute to an experimental analysis of social preference within a social reinforcement framework, drawing on methods with proven efficacy in the analysis of reinforcement more generally.

Actions in Slow Motion: Theoretical and Methodological Reflections on Temporality in Actions and Intersubjective Understanding

This article examines the connection between actions, temporality, and media-based observation. Slow motion technology is currently being used especially in sports to examine and evaluate athletes’ actions more precisely in order to identify potential infringements of rules. Starting with a phenomenological perspective, this article engages in a critical assessment of the degree to which the intentions underlying athletes’ actions become clearer if their actions are slowed down using slow motion. It transpires that a more in-depth understanding is not possible because the process of time-stretching using media technology tends to obscure intersubjective understanding. Nevertheless, the use of different playback speeds does increase observers’ sensitivity to the temporality of action and observation. This is particularly the case when greater emphasis is placed on the body and its role in the formation and carrying out of intentions. With the phenomenological view and in special consideration of the body and the subjective intentionality, the paper contributes to a discussion about the connection of time and (inter-)action already led in ethnomethodology and conversation analysis. These findings mark a contribution to empirical social research as well, which is increasingly using video material in action analysis and should take slow motion as a possible augmented but also manipulated access to actions into account adequately. To this end, this article suggests a method for identifying the merits and demerits of using slow motion to analyse actions, and discusses the methodological implications of temporality in observation.

     

Rain,Rain Go Away! A Diary Study on Morning Weather and Affective Well-Being at Work

Weather determines a number of affective experiences in everyday life. Although affective events theory positions environmental features such as the weather as important in determining affective well-being also at work, research in this regard has mainly focused on predictors within the person or work context. Addressing this gap, we studied how daily morning weather relates to day-specific affective well-being at work. Specifically, we examined vigor and job satisfaction as positive well-being states, and negative affect and burnout as negative well-being states. Additionally, we examined individual weather sensitivity and positive/negative affectivity as person-level moderators of the daily weather–well-being relationship. Using data gathered in a diary study with 115 employees reporting on 457 workdays, we found morning weather to be related to state vigor and job satisfaction, but not to negative affect and burnout. Positive affectivity moderated the relationships between morning weather and job satisfaction as well as burnout. Weather sensitivity moderated the relationship between morning weather and vigor, while negative affectivity did not moderate any relationship between morning weather and well-being at work. Our results contribute to the understanding of affective well-being at work by pointing at the role environmental factors such as weather conditions can play.     

Entrepreneurial Passion: A Review,Synthesis, and Agenda for Future Research

The present study undertakes a comprehensive and critical review of the body of empirical work on entrepreneurial passion. In particular, we document how the “first generation” of research on entrepreneurial passion and work passion in entrepreneurs has gained growing attention in various sub-fields of entrepreneurship research including entrepreneurial management, psychology, and finance. We provide an overview over theories used, definitions and measurements adopted, research methods utilized (e.g., qualitative vs. quantitative, survey-based vs. experimental/intervention), the thematic focus of studies, and unit of investigation (e.g., individual vs. team). We not only flag the problems of inconsistencies and limitations with respect to theory use, the making of causal inferences, and the conceptualization and measurement of entrepreneurial passion in existing studies (e.g., jingle fallacies), but also review the antecedents and outcomes of entrepreneurial passion identified in prior work and work where it had been examined as a moderator. Following this, we offer a research agenda with concrete suggestions to act as a foundation for the “second generation” of entrepreneurial passion research that proactively addresses the issues and gaps identified in our review. Finally, we also highlight how insights from the entrepreneurial passion literature can inform scholarship on passion more broadly.

A combination of combat experience,early abduction,and severe traumatization fuels appetitive aggression and violence among abductees of rebel war in Northern Uganda

Individuals who perpetrate violence may likely perceive violence as appealing and infliction of violence to derive pleasure is termed as appetitive aggression. Individuals who were abducted as children into an armed group often experience a higher number of traumatic event types, that is traumatic load and are usually socialized in a violence-endorsing environment. This study aims to investigate the interaction between age at initial abduction with that of traumatic load, and their influence on appetitive aggression along with perpetration of violent acts by former members of an armed rebel group of both sexes. Semi-structured interviews were conducted among a target group of formerly abducted rebel-war survivors (including participants with and without combat experience) from Northern Uganda. Participants included 596 women and 570 men with N = 1,166 (M_age = 32.58, SD_age = 9.76, range: 18–80 years). We conducted robust linear regression models to investigate the influence of age at initial abduction, traumatic load, combat experience, and biological sex on appetitive aggression as well as their perpetrated violent acts. Our study shows, appetitive aggression and the number of perpetrated violent acts were specifically increased in individuals who were abducted young, experienced several traumatic events in their lifetime, and with previous combat experience. For perpetrated violence men showed increased levels whereas for appetitive aggression the association was independent of biological sex. Therefore, early abducted individuals with a higher traumatic load, who have combat experience, need to be given special intervention to prevent any further violence.     

The Ideological Foundations of Economic Protectionism: Authoritarianism,Social Dominance Orientation,and the Moderating Role of Political Involvement

Even though economic globalization and foreign trade are major topics in the political discourse of most societies and negative attitudes toward international trade are prevalent, there is a lack of research investigating the ideological roots of protectionist preferences from a psychological perspective. In the present research, we examined the implications of right-wing authoritarianism (RWA) and social dominance orientation (SDO) for trade attitudes. Using data from two nationally representative samples from the United States (Study 1) and Germany (Study 2), we found that RWA predicted protectionist attitudes above and beyond economic self-interest. Furthermore, we found that the relationship between RWA and opposition to international trade was moderated by political involvement. The association of SDO with protectionist attitudes was inconsistent across the two studies and was not moderated by political involvement. Taken together, these results emphasize the importance of basic ideological orientations and the psychological dispositions they reflect in explaining public attitudes toward international trade.

Simulated judicial decision-making for African and European American adolescents with illegal sexual behavior: The impact of medical data and victim race/ethnicity

The perceived importance of victim and defendant race/ethnicity and medical evidence in child sexual abuse cases has been recognized separately in the literature. However, few studies have considered these factors simultaneously. Within a sample of 880 college students, an interaction effect was tested between the presence of medical evidence and the race/ethnicity of a juvenile defendant and victim using child sexual abuse case vignettes. The main effects of medical evidence and the race of the defendant were observed. Medical evidence and race of victim influenced victim believability such that medical evidence was more impactful for cases with African American victims. Further, there were interactions between the race of the defendant and the race of the victim in adult versus juvenile court decisions, sex offender registration and notification requirements, and length of sex offender registration and notification. Interracial sexual offending was associated with substantially higher punishment than intraracial sexual offending. Accordingly, several important implications for court-level decision-making processes are explored.
