Description
Infectious diseases have been a major threat to survival throughout human history. Humans have developed a behavioral immune system to prevent infection by causing individuals to avoid people, food, and objects that could be contaminated. This current project investigates how ambient temperature affects the activation of this system. Because temperature is positively correlated with the prevalence of many deadly diseases, I predict that temperature moderates the behavioral immune system, such that a disease prime will have a stronger effect in a hot environment compared to a neutral environment and one's avoidant behaviors will be more extreme. Participants were placed in a hot room (M = 85F) or a neutral room (M = 77F) and shown a disease prime slide show or a neutral slide show. Disgust sensitivity and perceived vulnerability surveys were used to measure an increased perceived risk to disease. A taste test between a disgusting food item (gummy bugs) and a neutral food item (gummy animals) measured food avoidance. There was no significant avoidance of the gummy and no significant difference in ratings of disgust sensitivity or perceived vulnerability as a function of temperature conditions. There were no significant interactions between temperature and disease. The conclusion is that this study did not provide evidence that temperature moderates the effect of disease cues on behavior.

Description
Anti-atheist prejudice is cross-culturally prevalent and marked by intuitive distrust. However, recent research suggests that, when social perceivers know additional relevant information about others (i.e., their reproductive strategies), this information overrides religious information and nonreligious targets are trusted as much as religious targets. That is, perceivers seem to use religious information as a cue to a specific set of behavioral traits, but prioritize direct information about these traits when available. Here, I use this framework to explore the possibility that atheists are viewed positively in certain circumstances. First, atheists might be viewed positively for certain purposes because of their perceived reproductive strategies, even while being trusted less. Second, atheists who are family-oriented do not sacrifice trust, but may still be viewed positively for other traits (i.e., open-mindedness, scientific thinking). Third, given the constraints religion often imposes on behavior, atheists might be trusted more in situations where these constraints interfere with religious people’s inclination to cooperate. I tested these hypotheses using fictitious social media profiles to examine social perception. The study had a 3 (Target Religion: Religious, Nonreligious, or Atheist) × 3 (Target Reproductive Strategy: No Information, Committed, Uncommitted) experimental design (N = 550). Contrary to my predictions, participants did not rate atheists and nonreligious targets as “fast” compared to religious targets. Consistent with predictions, however, atheists and nonreligious individuals were rated significantly higher on perceived open-mindedness and scientific thinking. Finally, atheist and nonreligious targets were trusted more in two of the three trust domains: trust with scientific findings that contradict their worldview and trust with a secret about a friend’s abortion. Further analyses compared patterns of responding for religious and nonreligious individuals, finding evidence for ingroup bias in most perceptions, but not all. Results suggest that perceptions of atheists are complex, but that atheists may, at least sometimes, be viewed favorably. Finally, these results point to the importance of reproductive strategy as a dimension of social perception, as this variable had a clear effect, independent of target religion, on the hypothesized perceptions.

Description
Transgenic experiments in Drosophila have proven to be a useful tool aiding in the
determination of mammalian protein function. A CNS specific protein, dCORL is a
member of the Sno/Ski family. Sno acts as a switch between Dpp/dActivin signaling.
dCORL is involved in Dpp and dActivin signaling, but the two homologous mCORL
protein functions are unknown. Conducting transgenic experiments in the adult wings,
and third instar larval brains using mCORL1, mCORL2 and dCORL are used to provide
insight into the function of these proteins. These experiments show mCORL1 has a
different function from mCORL2 and dCORL when expressed in Drosophila. mCORL2
and dCORL have functional similarities that are likely conserved. Six amino acid
substitutions between mCORL1 and mCORL2/dCORL may be the reason for the
functional difference. The evolutionary implications of this research suggest the
conservation of a switch between Dpp/dActivin signaling that predates the divergence of
arthropods and vertebrates.

Description
The present study tested the hypothesis that women dress modestly to signal to other women that they pose no mate poaching threat and are sexually restricted, and that this is especially true for religious women. Participants were 392 Muslim women living in the United States. They read two passages describing fictional situations in which they met with a potential female friend and then indicated what kind of outfit they would wear in both situations. In one situation, the participant obtained a reputation for promiscuity; in the other situation, reputation was not mentioned. I predicted that participants would choose more modest outfits for the promiscuous reputation passage, because if women dress modestly to signal sexual restrictedness, then they should dress more modestly around women with whom they have a reputation for promiscuity—to counteract such a reputation, women may wish to send a strong signal that they are not promiscuous. The hypothesis was partially supported: Less religious women chose more modest outfits for the promiscuous reputation situation than they did for the no reputation situation. This suggests that some women dress modestly to signal sexual restrictedness to other women, but that this is especially true for women who are less religious, not more. More religious women dress more modestly than less religious women, but they may not dress modestly to signal sexual restrictedness. Two important goals for this area of research are to determine the proximate reasons that more religious women dress modestly and to investigate modest dress among non-Muslim religious women.

Description
National surveys indicate that Americans hold greater prejudice toward atheists than many other historically stigmatized groups. The religious prosociality perspective posits that people will demonstrate prejudice toward anyone who does not believe in a monitoring and punishing god, including atheists, because of the perception that those who lack belief in a monitoring and punishing god cannot be trusted to act in a prosocial manner. The sociofunctional perspective posits that people will demonstrate distinct forms of prejudice toward individuals who present certain types of threats to the group, and previous research suggests that atheists are perceived as posing a threat to group values. In the current study, participants rated targets whose values largely matched their own values more favorably than targets whose values did not largely match their own values. Also, participants rated both targets who believed in a monitoring and punishing god and targets who believed in a god who does not monitor nor punish more favorably than atheist targets. These judgments spanned a variety of measures, including emotional reactions to the target, judgments of target traits, and preferred social distance from the target. Results were consistent with the sociofunctional perspective but did not support the religious prosociality perspective.
