Humans use emotions to communicate social cues to our peers on a daily basis. Are we able to identify context from facial expressions and match them to specific scenarios? This experiment found that people can effectively distinguish negative and positive emotions from each other from a short description. However, further research is needed to find out whether humans can learn to perceive emotions only from contextual explanations.

This study investigates the effects of familiarity and the size of a novel object on perception of depth. Familiar size is a visual depth cue that provides information about the distance of an object. This project explores if the familiar size illusion is a result of an automatic perceptual process or an intellectual thought process. This data was collected in two phases, a familiarization phase and a testing phase. The experimental participants were familiarized for 30 seconds with a novel object, while the control group was not shown any objects prior to presentation of test objects. The novel test stimuli were constructed in 5 sizes and participants in the familiar group were familiarized with the medium size object. Participants were then asked to indicate the perceived distance of different sized objects by moving a rod with a pointer at the end to match the distance. The smaller comparison objects subtended visual angles that participants had not previously experienced, while larger comparison objects produced a larger visual angle than the participants had seen during the familiarization phase. The testing phase was identical for both familiar and unfamiliar control groups. Apparent distance was influenced by the size of the objects. Larger objects were judged to be closer than the smaller objects. Participants not familiarized showed smaller effects of stimulus size than the familiarized group. The effect of familiarity was not significant for the smaller stimuli but was very significant for the larger stimuli. The results were not consistent with the cognitive theory which argues that familiar size is a result of a conscious thought process. These outcomes are predicted under the model of familiar size being an automatic perceptual process.

South Asian students are known for having immense pressure on them due to parental expectation and oftentimes that stress can present in psychosomatic symptoms. This investigation aimed to better understand the physical presentations of stress and how South Asians compare to their white peers. An online study was conducted with both South Asian (n = 15) and White (n = 58) individuals that use the Perceived Stress Scale and the New York State United Teachers physical stress assessment to understand the differences in stress. It was found that South Asians have a higher average perceived stress core of 25 versus 20 for whites and experience headaches, sore neck, an overall feeling of worry and anxiety, and diarrhea more frequently than their white counterparts. This suggests that South Asians may in fact have more psychosomatic manifestations of stress. It is posited that this is due to South Asian students not having an adequate outlet in which they can express negative emotions.

The structure of this project will open with the dangers posed by inadequate screening techniques to both individuals with Body Dysmorphic Disorder and their plastic surgeons. This discussion will be followed by a summary of the existing mental health screenings implemented in plastic surgery clinics and their limitations. The assessments that will be examined include The Body Dysmorphic Disorder Examination, The Body Dysmorphic Disorder Examination - Self-Report, The Cosmetic Procedure Screening Questionnaire, The Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder, and The Body Dysmorphic Disorder Questionnaire. These screening techniques were chosen based on a multitude of factors: frequency of use in psychiatric and cosmetic settings, innovation of screening methodology, and significance of studies that utilize the assessments. After describing the screening techniques, there will be a brief discussion of the limitations of developing a screening method for Body Dysmorphic Disorder, along with suggestions for methodology in future research. This thesis will demonstrate that no existing screening method for Body Dysmorphic Disorder in aesthetic surgery is flawless. Still, future research efforts should investigate combining questionnaires and clinical interviews to screen for the disorder within clinics efficiently and more reliably.

The climate conversation is growing more important and necessary than ever. The media has a way of promoting a "doom and gloom" sentiment over conservation efforts and what the public has the power to do in terms of making a change. Now due to the effects of COVID-19 on the population's attention spans and memories, there is a need for a way to communicate climate science effectively and to encourage those who feel discouraged by climate change to find their inner power. The answer lies in photography. Making science accessible and intriguing through the art of photography is what can get people more interested and empowered to fight against climate change and alter their attitudes towards environmentalism. This thesis explains psychological research and the reasons why people feel helpless in terms of our global future. In then dives into human subjects research conducted on ASU's campus and how the survey results argue in favor of the paper's hypothesis. Additionally, ways to get involved and reasons why we need to remain hopeful are discussed.

As the use of social media becomes more prevalent, especially in adolescents and young adults, there is a growing need to understand how social media use affects psychological well-being in the emerging adult population. Prior research has found that exposure to nature reduces stress and increases attention in comparison to urban environments, but nature has not been studied as a way to reduce the potentially negative effects of social media. The current study aimed to determine if viewing social media or nature for a brief time affected psychological well-being, social comparisons, future self-identification, and awe, and to test whether viewing nature scenes could buffer the effects of viewing social media. Data was collected from 275 participants using a survey on Amazon Mechanical Turk. Results showed that emerging adults exposed to nature scenes had significantly less negative affect compared to those exposed to their social media feeds. Exploratory analyses showed that those who spent more time outside tended to experience decreased negative affect when they viewed both social media and nature photos, but those who spent more time outside experienced increased negative affect when only viewing social media. Those who used social media more often generally experienced lower negative affect. Findings show that relations between humans, social media, and nature, are complex, and further research into these relations and their underlying causes may be beneficial.
