The Adaptive Value Of Complex Socio-Communicative Behavior, Sara A. Skiba

Master of Science in Integrative Biology Theses

Human spoken language represents the most elaborate communication system, however the selection pressures leading to its emergence are still uncertain. Unlike humans, bonobos and chimpanzees do not have language. However, bonobos may have been subjected to similar selection pressures as early hominins, subsequent to their phylogenetic split from chimpanzees roughly 1.5 million years ago. The current study investigated the similarities and differences in sociality and communicative production between bonobos and chimpanzees in captive settings, using 9, 10-minute focal follows for each individual. Analyses revealed a significant positive correlation between social proximity score and total communicative signals produced, as well as …

Bridging The Empathy Gap: Effects Of Brief Mindfulness Training On Helping Outgroup Members In Need, Daniel R. Berry

Theses and Dissertations

Witnessing others in need can be felt similarly to experiencing it oneself (empathy) and motivates assistance of those in need (prosocial action). It is well-documented that empathy can occur automatically, but when those in need are not members of a social ingroup, empathy and prosocial action are undermined. One major ingroup—outgroup division in American and in other countries is based on race. Although most condemn racial discrimination, empathy and prosocial action are often lower, however unintentionally, in interracial contexts. In light of this empathy gap, it is important to identify psychological factors that could bolster empathy and prosocial action toward …

To Help Or Not To Help? Assessing The Impact Of Envy And Gratitude On Prosocial Behaviors, Anna Maria C. Behler

Theses and Dissertations

Envy is an other-oriented but negative emotion; no research has examined the influence of envy on prosocial behavior. Study 1 examined whether envy and gratitude would promote or inhibit prosocial behavior. I hypothesized that envy would result in less helping behavior than a neutral condition, whereas gratitude would increase helping behavior. Results supported the hypothesis that envy inhibits prosocial behavior. There was not enough evidence to suggest that gratitude promoted helping.

Study 2 examined how envy and gratitude affected prosocial behavior when participants were given the choice to help or harm others. I hypothesized that experiencing envy would result in …
