Description
Exploration of a mouse model (C57BL/6J) capable of demonstrating behavioral changes after adolescent social isolation that are consistent with prior findings may prove beneficial in later research. This study examined 2 proposed long-term effects of isolated housing (one mouse/cage), when compared to group housing (two mice/cage) during adolescence. Mice were placed in their respective housing conditions after weaning (PND 21) and remained in those conditions until PND 60. The same cohorts were used in both phases of the experiment. Phase 1 sought to confirm previous findings that showed increases in ethanol intake after adolescent social isolation using a 2-bottle preference Drinking-in-the-Dark (DID) design over a 4-day period (PND 64-PND 67.). Phase 2 sought to elucidate the effects present after adolescent social isolation, as measured using response inhibition capabilities demonstrated during fixed-minimum interval (FMI) trials (PND 81-PND 111). Findings in phase 1 of the experiment were non-significant, save a strong tendency for female mice in both housing conditions to drink more as a proportion of their bodyweight (g/kg). However, a trend of lower bodyweight in single housed mice did exist, which does suggest that detrimental stress was applied via the used of adolescent isolation in that housing condition. Findings in phase 2 showed little effect of adolescent social isolation on mean inter-response time (IRT) at any criterion used (FMI-0, FMI-4, FMI-6). Evaluation of mean interquartile range (IQR) of IRTs showed a significantly greater amount of variation in IRT responses within single housed mice at the highest criterion (FMI-6), and a trend in the same direction when FMI-4 and FMI-6 were tested concurrently. Taken as a whole, the findings of this experiment suggest that the effect of adolescent social isolation on ethanol intake is far less robust than the effect of sex and may be difficult to replicate in a low-power study. Additionally, adolescent social isolation may interfere with the ability of mice to show consistent accuracy during FMI tasks or a delay in recognition of FMI criterion change.

Description
As a democratic innovation involving deliberation and decision making, participatory budgeting (PB) often catalyzes powerful changes among individual participants and within their respective communities. Certain models of PB designate autonomous spaces for young people to determine how to spend a portion of a particular budget, typically that of a municipality or school. These processes of youth PB may address recent trends in the underrepresentation of youth in civic spaces. Following the initial launch of youth participatory budgeting (youth PB) in Cluj (Romania), I spent three weeks in Cluj conducting 45 semi-structured interviews with youth PB participants and one focus group with youth PB facilitators. This thesis explores two areas: (a) the main dynamics of the online Cluj youth PB process (team development and organization, themes of projects proposed and their intended impacts, and inclusion throughout the process) and (b) impact of youth PB on participants (participant learning, change, and empowerment). Main findings suggest that organized groups with ongoing projects dominated the youth PB process and that a majority of projects aspired to impact either all residents of Cluj or a specific youth group (e.g. young artists, young engineers), while very few projects intended to impact young people in Cluj broadly. More than 85% of participants reported feeling empowered by involvement in youth PB. Some differences in learning and change were found by gender, ethnicity, and age. Key recommendations for future iterations of this process include establishing deliberation between teams, encouraging informal group development, restructuring the voting process, and enhancing inclusion of ethnic minorities and migrants.

Description
Contextual cues can impact how statements are perceived. Specifically, they may be perceived as more aggressive than they otherwise would be. For the study, both medium of communication (in-person versus online) as well as how competitive the context was (non-competitive or competitive) were examined, with a bit of focus on gender. 130 Arizona State University students enrolled in Psychology 101 were surveyed; the mean age was 19.32 (SD = 1.43). A 2x2 factorial design was used, consisting of four possible conditions: In-person/Competitive, Online/Competitive, In-person/Non-Competitive, and Online/Non-Competitive. Participants read two scenarios, each featuring a target character who says an ambiguous statement, and each scenario with one of the four conditions at random. One scenario involved earning a promotion, and the other involved trying to win a voucher via mini-golf. After, participants answered questions regarding how they felt about the intent of the ambiguous statement, how the participant would feel in the scenario, and what kind of person the participant felt the target character was. Exploratory Factor Analysis with Principal Axis Factoring and Direct Oblimin Rotation was used to find outcome variables. We hypothesized that Perceived Aggression and Participant Negative Emotion would be higher in both the competitive condition as well as the online condition, and that Perceived Agreeableness would be higher in both the non-competitive condition as well as the in-person condition; this applied for both scenarios. The results were mostly not statistically significant, and contrary to the hypotheses, Perceived Aggression and Participant Negative Emotion were higher in the in-person condition than the online condition. However, as predicted, Perceived Agreeableness was higher for the in-person condition, and the competitive led to higher levels of Perceived Aggression and Participant Negative Emotion, along with lower levels of Perceived Agreeableness, as opposed to the non-competitive condition. Limitations included a small age range and only one type of online communication (instant messaging), along with the fact that the study was a survey. Future studies are needed to examine what factors affect perception of aggression, as very few have been conducted.

Description
Abstract The current study examined how people perceive three different types of relationships: Sugar Baby/Sugar Daddy (SB/SD) relationships, same-sex relationships, and heterosexual relationships. In an online survey, undergraduate students rated these different types of couplings on overall general view, acceptability and approval. Additionally, survey participants were asked to complete measures of religiosity and socio-sexual orientation to investigate whether these individual measures moderated ratings. Overall, SB/SD relationships were rated the most negatively, least acceptable, and least approved of out of the three relationship types. Following SB/SD relationships are same-sex relationships and then lastly heterosexual relationships. Higher religiosity scores led to lower general views, acceptability, and approval ratings of SB/SD relationships. The opposite pattern emerged for socio-sexuality such that higher socio-sexuality scores correlated to higher general views, acceptability, and approval ratings of SB/SD relationships. The findings suggest that societal views toward alternative relationship types are negative, relative to traditional heterosexual couplings, and these views may be exacerbated in the case of more, as opposed to less novel pairings. Just as cross-race and same-sex relationships have faced adversity in the past (Testa, 1987), newer types of relationships, such as SB/SD, that don't follow traditional conventions are still bound to face negativity. Moreover, these views are not monolithic in that individual differences based on religiosity and socio-sexuality lead to variation in judgments. The data presented herein represent an initial exploration of SB/SD relationships, a phenomenon that is increasing in frequency and about which many questions remain.

Description
Human perceptual dimensions of sound are not necessarily simple representations of the actual physical dimensions that make up sensory input. In particular, research on the perception of interactions between acoustic frequency and intensity has shown that people exhibit a bias to expect the perception of pitch and loudness to change together. Researchers have proposed that this perceptual bias occurs because sound sources tend to follow a natural regularity of a correlation between changes in intensity and frequency of sound. They postulate that the auditory system has adapted to expect this naturally occurring relationship to facilitate auditory scene analysis, the tracking and parsing sources of sound as listeners analyze their auditory environments. However, this correlation has only been tested with human speech and musical sounds. The current study explores if animal sounds also exhibit the same natural correlation between intensity and frequency and tests if people exhibit a perceptual bias to assume this correlation when listening to animal calls. Our principal hypotheses are that animal sounds will tend to exhibit a positive correlation between intensity and frequency and that, when hearing such sounds change in intensity, listeners will perceive them to also change in frequency and vice versa. Our tests with 21 animal calls and 8 control stimuli along with our experiment with participants responding to these stimuli supported these hypotheses. This research provides a further example of coupling of perceptual biases with natural regularities in the auditory domain, and provides a framework for understanding perceptual biases as functional adaptations that help perceivers more accurately anticipate and utilize reliable natural patterns to enhance scene analyses in real world environments.

Description
The transition from high school to college is associated with considerable life strain for adolescents, including higher reported levels of daily stress and negative affect (NA), and alterations in stress physiology have been linked to poor health. The purpose of this thesis was to use an ecological momentary assessment design to study associations between momentary experiences of negative affect and cortisol levels in a sample of adolescents transitioning to college. I also examined the potential moderating effects of two potential vulnerability or protective factors, alone status and perceived social support from friends. Adolescents provided salivary samples and completed paper-and-pencil diary reports of socioemotional experiences and alone status five times per day for three consecutive weekdays, as well as completed self-report questionnaires on perceived social support from friends. Within-person increases in momentary negative affect were associated with momentary cortisol reactivity. Alone status significantly moderated this association such that the association between momentary negative affect and momentary cortisol levels was only significant when individuals were with others and not when they were alone. Perceived social support from friends did not significantly moderate the within-person associations between negative affect and momentary cortisol levels. The findings add to our understanding of physiological correlates of socioemotional experiences, as well as contexts in which these associations may be exaggerated or attenuated. The findings inform our understanding of potential pathways by which physiological reactivity to socioemotional experiences may affect the health of adolescents as well as how prevention efforts could reduce potential poor health outcomes associated with heightened stress reactivity.

Description
Tempo control is a crucial part of musicianship that can provide an obstacle for novice musicians. The current study examines why novice percussionists increase their playing tempo when they increase their loudness (in music, loudness is referred to as dynamics). This study tested five hypotheses: 1) As actual tempo changes, listeners perceive that the tempo is changing; 2) There is a perceptual bias to perceive increases in acoustic intensity as also increasing in tempo; 3) All individuals, regardless of percussion experience, display the bias described in hypothesis 2; 4) Unskilled or non-percussionists increase or decrease produced tempo as they respectively increase or decrease loudness; and 5) Skilled percussionist produce less change in tempo due to changes in loudness than non-percussionists. In Experiment 1, percussionists and non-percussionists listened to metronome samples that gradually change in intensity and/or tempo. Participants identified the direction and size of their perceived tempo change using a computer mouse. In Experiment 2, both groups of participants produced various tempo and dynamic changes on a drum pad. Our findings support that both percussionists and non-percussionists, to some extent, display a perceptual bias to perceive tempo changes as a function of intensity changes. We also found that non-percussionists altered their tempo as a function of changing dynamic levels, whereas percussionists did not. Overall, our findings support that listeners tend to experience some integrality between perceptual dimensions of perceived tempo and loudness. Dimensional integration also persists when playing percussion instruments though experience with percussion instruments reduces this effect.

Description
This thesis aimed to discover the risks of being a high achieving student, in secondary school contexts. With the growing concern for college admission, the high achieving student has become more prevalent within society. This paper sought to gain deeper understanding into the risks and implications of attempting to achieve excellence for high achievers. Interviews with three frontline personnel at two college preparatory schools and one International Baccalaureate degree program were conducted. It was found that in the studied geographic location, peer pressure and relations, parental pressure, perfectionism, extra-curricular activities, college admission, mental health implications, and coping mechanisms are themes that are highlighted through interviews with primary staff of high achieving students. Although personnel at each of these secondary schools were clearly aware of the stress experienced by their students, a disparity remained between how certain programs managed the stress and how it negatively impacted students. College preparatory faculties appear to be more involved and current on their students' stress. This study was limited and further research should be conducted in the future that expands on this concept in various sociogeographic locations.

Description
Introspective awareness refers to direct access to one’s own internal and subjective thoughts and feelings (Wimmer & Hartl, 1991). Two theories, simulation theory and theory-theory, have been used to understand our access to our mental states. Simulation theory (Harris, 1991) involves imagining yourself in another person’s situation, reading off of your mental state, and attributing that state to the other person. Theory-theory (Gopnik, 1993) involves an interrelated body of knowledge, based on core mental-state constructs, including beliefs and desires, that may be applied to everyone—self and others (Gopnik & Wellman, 1994). Introspection is taken for granted by simulation theory, and explicitly denied by theory-theory. This study is designed to test for evidence of introspection in young children using simple perception and knowledge task. The current evidence is against introspective awareness in children because the data suggest that children cannot report their own false beliefs and they cannot report their on-going thoughts (Flavell, Green & Flavell, 1993; Gopnik & Astington, 1988). The hypothesis in this study states that children will perform better on Self tasks compared to Other tasks, which will be evidence for introspection. The Other-Perception tasks require children to calculate the other’s line of sight and determine if there is something obscuring his or her vision. The Other-Knowledge tasks require children to reason that the other’s previous looking inside a box means that he or she will know what is inside the box when it is closed. The corresponding Self tasks could be answered either by using the same reasoning for the self or by introspection to determine what it is they see and do not see, and know and do not know. Children performing better on Self tasks compared to Other tasks will be an indication of introspection. Tests included Yes/No and Forced Choice questions, which was initially to ensure that the results will not be caused by a feature of a single method of questioning. I realized belatedly, however, that Forced Choice was not a valid measure of introspection as children could introspect in both the Self and Other conditions. I also expect to replicate previous findings that reasoning about Perception is easier for children than reasoning about Knowledge.

Description
Community Action Research Experiences (CARE) collaborated with Citizenship Counts, a local non-profit organization that provides free civics curriculum to middle and high school teachers nationwide, to evaluate the effectiveness of the current curriculum and create additional curriculum materials. Data were collected over a three-month period through online and paper surveys distributed to teachers who had used some aspect of the Citizenship Counts curriculum previously. Of the teachers contacted, nineteen responded with completed surveys. The results indicate that teachers are pleased with their experience working with Citizenship Counts, but that there were areas where improvements could be made. The additional curriculum materials created were quizzes, which can be added to the Citizenship Counts curriculum as an additional improvement. The main areas of concern from teachers were the Citizenship Counts website and additional help when planning Naturalization Ceremonies.
