Description
There are several visual dimensions of food that can affect food intake, example portion size, color, and variety. This dissertation elucidates the effect of number of pieces of food on preference and amount of food consumed in humans and motivation for food in animals. Chapter 2 Experiment 1 showed that rats preferred and also ran faster for multiple pieces (30, 10 mg pellets) than an equicaloric, single piece of food (300 mg) showing that multiple pieces of food are more rewarding than a single piece. Chapter 2 Experiment 2 showed that rats preferred a 30-pellet food portion clustered together rather than scattered. Preference and motivation for clustered food pieces may be interpreted based on the optimal foraging theory that animals prefer foods that can maximize energy gain and minimize the risk of predation. Chapter 3 Experiment 1 showed that college students preferred and ate less of a multiple-piece than a single-piece portion and also ate less in a test meal following the multiple-piece than single-piece portion. Chapter 3 Experiment 2 replicated the results in Experiment 1 and used a bagel instead of chicken. Chapter 4 showed that college students given a five-piece chicken portion scattered on a plate ate less in a meal and in a subsequent test meal than those given the same portion clustered together. This is consistent with the hypothesis that multiple pieces of food may appear like more food because they take up a larger surface area than a single-piece portion. All together, these studies show that number and surface area occupied by food pieces are important visual cues determining food choice in animals and both food choice and intake in humans.

Description
The unpleasant bitter taste found in many nutritious vegetables may deter people from consuming a healthy diet. We investigated individual differences in taste perception and whether these differences influence the effectiveness of bitterness masking. To test whether phenylthiocarbamide (PTC) `supertasters' also taste salt and sugar with greater intensity, as suggested by Bartoshuk and colleagues (2004), we infused strips of paper with salt water or sugar water. The bitterness rating of the PTC strip had a significant positive linear relationship with ratings of both the intensity of sweet and salt, but the effect sizes were very low, suggesting that the PTC strip does not give a complete picture of tasting ability. Next we investigated whether various seasonings could mask the bitter taste of vegetables and whether this varied with tasting ability. We found that sugar decreased bitterness and lemon decreased liking for vegetables of varying degrees of bitterness. The results did not differ by ability to taste any of the flavors. Therefore, even though there are remarkable individual differences in taste perception, sugar can be used to improve the initial palatability of vegetables and increase their acceptance and consumption.

Description
A prior experiment by Li and colleagues found that when participants rated same sex faces in physical attractiveness, their self-reports of religiosity were higher in comparison to those that rated opposite sex faces. Could this be due to participants feeling their sexuality was threatened or misunderstood? In the current experiment, we attempted to replicate these findings and extend them by using a pseudo personality test that presented false feedback to participants. This feedback explained that their personalities were similar to homosexual or heterosexual people. Four hundred and fifty participants from Amazon Mturk were randomized into these conditions. We also measured homophobia, moral values, and the believability of the experiment. Results displayed no replication of the original findings. Men were more homophobic than women, while displaying lower moral values and religiosity. Those that self-reported being more homophobic also reported being more religious and moral. In conditions of sexual threat (homosexual personality, same sex faces) and sexual comfort (heterosexual personality, opposite sex faces), self-reports of moral values increased. Participants that reported believing the feedback displayed higher religiosity in both sexual threat and sexual comfort conditions. For a more concrete understanding of the relationship between religiosity, mating goals, and threats to sexuality, more research needs to be performed.

Description
Statistics are rising for adults who are overweight and/or obese, putting them at higher risk of developing serious health problems. Eating fewer portions of vegetable than the daily-recommended amounts contributes to this increase with. College students, being more susceptible to weight gain as they are transitioning from childhood to adulthood. Previous studies demonstrated that children ate more vegetables when repeatedly paired with a low-fat dip compared to when served plain. The current study examined whether this effect was also successful in college-aged subjects. A total of 148 (55 males, 91 females) college-aged students from an introductory psychology class at Arizona State University (Tempe, AZ) participated in the study. Subjects were randomly assigned to receive cauliflower or broccoli (raw) either served plain or with low-fat ranch dressing. Subjects showed a greater preference for and consumption of the vegetable plain that was previously given with dip than without dip. These findings suggest that serving vegetables with low-fat ranch dip two times can increase the liking and consumption of vegetables in college students.

Description
When discussing gay literature in the French, contemporary sphere, one of the most up
and coming and prominent authors is Édouard Louis. His works’ focus on the realism and
violence of the working class offers a critical and necessary perspective of the gay experience in
modern-day France. While recent in their creation, Louis’ works follow a connecting thread that
is inseparable from other autofiction novels that have a narrator with same sex attractions such as
Annie Ernaux’s Ce qu’ils disent or rien and Didier Eribon’s Retour à Reims. Often commonly
discussed as French LGBT literature, these autofictional works that extend from Gide to Eribon
to now Louis demonstrate how the proposed societal dualities, limitations, and hierarchies
described by philosophers like Michel Foucault and Judith Butler affect homosexual
performativity. Louis’ first novel En finir avec Eddy Bellegueule, published on January 2, 2014,
offers another illustration of this analysis. It specifically describes the metaphysical
(metaphysical being the relationship between the outer stimuli and internal perspective) effects
and constraints of current poverty on homosexual performativity. By analyzing En finir avec
Eddy Bellegueule through this theoretical framework of power and poverty, this thesis adds a
theoretical and intersectional nuance to the narrative voice that current literature focusing on the
novel’s landscape mentions but does not reflect on. I argue that it is important to attach an
autofictional timeline that is necessary to promote and apply future ontological doctrines to this
genre.
