Do zoo visitors induce attentional bias effects in primates completing cognitive tasks?

Animal Cognition - While previous research has focused on the impact of visitors on zoo-housed animals’ behavior, here, we evaluated the impact of visitors on the performance of four...     

Understanding users' switching intention of cloud storage services: A push-pull-mooring framework

Highly sensitive and private information is stored in the cloud, so understanding how and why customers choose and switch between cloud storage service providers is pivotal. However, prior studies have tended to focus on users' adoption of cloud storage services, whereas little attention has been paid to their switching intention behavior based on non-functional factors. Using the push-pull model, developed from human migration theory, and by employing a survey (n = 326), we demonstrate that the push factor (i.e., satisfaction) has a significant negative effect, while the pull factor (i.e., alternative attractiveness) has a significant positive effect on users' switching intentions. Furthermore, mooring factors such as switching costs, habitual use, and past switching experiences have a varying moderation effect on the relationship between push and pull factors and switching intentions. The results offer several important theoretical and actionable managerial implications.     

The Subjective Assessment of Accomplishment and Positive Relationships: Initial Validation and Correlative and Experimental Evidence for Their Association with Well-Being

In his Authentic Happiness Theory, Seligman describes three orientations that lead to happiness: The life of pleasure, the life of engagement, and the life of meaning (in Authentic happiness, Free Press, New York, 2002). The Orientations to Happiness Questionnaire (OTH; Peterson et al. in J Happiness Stud 6:25–41, 2005) has been developed as a subjective measure for these three orientations. In 2011, Seligman revised his theory and added two new components; i.e., positive relationships and accomplishment. These five are the basic tenets of his well-being theory. The present set of studies describes the construction and initial validation of two short scales for the subjective assessment of the endorsement of positive relationships and accomplishment. Their relation with the OTH-scales is also tested. Study 1 describes the scale construction and provides evidence for the factorial, convergent and divergent validity in three samples (n = 233, n = 336, and n = 125). Study 2 showed that the new scales have high test–retest reliabilities over a period of 1, 3, and 6 months (r = .68–.78), respectively. Study 3 examines the malleability of positive relationships and accomplishment in an intervention study that shows that the scores of both new scales increase in the intervention condition. Overall, the three studies show that the new scales have satisfactory psychometric properties—also when used together with the OTH-scales—and possible applications are discussed.     

Positive and negative intergroup contact predict Black and White Americans' judgments about police violence against Black Americans

We examined whether past positive and negative interracial contact predict people's views of interracial police violence. White (N = 207) and Black (N = 116) Americans reported on their past intergroup experiences before viewing information about one of two true events involving the death of a Black man at the hands of a White police officer. For White Americans, negative contact predicted a reluctance to blame the officer and a willingness to believe that people's responses to the events involved “playing the race card.” For Black Americans, positive contact predicted marginally less officer blame and lower beliefs that the victim was racially profiled. This suggests the potential for a vicious cycle, whereby past contact experiences color perceptions of intergroup conflict in the present.     

“Pure Joy”: Spinoza on Laughter and Cheerfulness

Laughter is a significant topic for Renaissance and seventeenth-century philosophers. Still, the latter rarely approved of laughter but endorsed it as useful mockery for theological or philosophical purposes. Benedict Spinoza’s view of laughter stands out as an exception to this attitude as well as to previous and later ones. Spinoza differentiates between mockery and laughter, denounces the former as evil, and characterizes the latter as “pure joy”: laughter is about oneself rather than another and originates in noticing something good, rather than base or ugly. In contrast to melancholy, cheerfulness is “always good” and is a precondition of our liberation as it furthers the use of reason. Not only is Spinoza’s view original, but it is an important source of the eighteenth-century notions of good-natured laughter and good humor through a more than probable influence on their proponent, the Earl of Shaftesbury. Whilst Spinoza’s view of cheerfulness is briefly addressed in recent studies, his view of laughter goes unnoticed in most commentaries and is misrepresented in humor studies. Contrary to what is assumed in the philosophy of laughter, I argue that the most important defense of laughter comes not from a British Enlightenment thinker, but from the Dutch Jewish seventeenth-century philosopher.
