Levels of heavy episodic drinking peak during emerging adulthood and contribute to the experience of negative consequences. Previous research has identified a number of trait-like personality characteristics that are associated with drinking. Studies of the Acquired Preparedness Model have supported positive expectancies, and to a lesser extent negative expectancies, as mediators of the relation between trait-like characteristics and alcohol outcomes. However, expectancies measured via self-report may reflect differences in learned expectancies in spite of similar alcohol-related responses, or they may reflect true individual differences in subjective responses to alcohol. The current study addressed this gap in the literature by assessing the relative roles of expectancies and subjective response as mediators within the APM in a sample of 236 emerging adults (74.7% male) participating in a placebo-controlled alcohol challenge study. The study tested four mediation models collapsed across beverage condition as well as eight separate mediation models with four models (2 beverage by 2 expectancy/subjective response) for each outcome (alcohol use and alcohol-related problems). Consistent with previous studies, SS was positively associated with alcohol outcomes in models collapsed across beverage condition. SS was also associated with positive subjective response in collapsed models and in the alcohol models. The hypothesized negative relation between SS and sedation was not significant. In contrast to previous studies, neither stimulation nor sedation predicted either weekly drinking or alcohol-related problems. While stimulation and alcohol use appeared to have a positive and significant association, this relation did not hold when controlling for SS, suggesting that SS and stimulation account for shared variability in drinking behavior. Failure to find this association in the placebo group suggests that, while explicit positive expectancies are related to alcohol use after controlling for levels of sensation seeking, implicit expectancies (at least as assessed by a placebo manipulation) are not. That the relation between SS and stimulation held only in the alcohol condition in analyses separate by beverage condition indicates that sensation seeking is a significant predictor of positive subjective response to alcohol (stimulation), potentially above and beyond expectancies.

When a sports performance is at its peak, it is akin to a musical performance in the sense that each player seems to perform their part effortlessly, creating a rhythmic flow of counterparts all moving as one. Rhythm and timing are vital elements in sports like basketball in which syncopated passing and shooting appear to facilitate accuracy. This study tests if shooting baskets “in rhythm,” as measured by the catch-to-release time, reliably enhances shooting accuracy. It then tests if an “in rhythm” timing is commonly detected and agreed upon by observers, and if observer timing ratings are related to shooting accuracy. Experiment 1 tests the shooting accuracy of two amateur basketball players after different delays between catching a pass and shooting the ball. Shots were taken from the three-point line (180 shots). All shots were recorded and analyzed for accuracy as a function of delay time, and the recordings were used to select stimuli varying in timing intervals for observers to view in Experiment 2. In Experiment 2, 24 observers each reviewed 17 video clips of the shots to test visual judgment of shooting-in-rhythm. The delay times ranged from 0.3 to 3.2 seconds, with a goal of having some of the shots taken too fast, some close to in rhythm, and some too slow. Observers rated if each shot occurs too fast, in rhythm slightly fast, in rhythm slightly slow, or too slow. In Experiment 1, shooters exhibited a significant cubic fit with better shooting performance in the middle of the timing distribution (1.2 sec optimal delay) between catching a pass and shooting. In Experiment, 2 observers reliably judged shots to be in rhythm centered at 1.1 ± 0.2 seconds, which matched the delay that leads to optimal performance for the shooters found in Experiment 1. The pattern of findings confirms and validates that there is a common “in rhythm” catch-to-shoot delay time of a little over 1 second that both optimizes shooter accuracy and is reliably recognized by observers.

An individual’s reputation can be beneficial or detrimental to their exchanges with others,
and these exchanges may be critical for achieving evolutionary goals, such as reproduction.
Depending on their reputation, an individual may or may not gain access to resources in order to
achieve their evolutionary goals. Reputation is typically described as being “positive” and
“negative,” but the current study aimed to identify potential nuances to reputations beyond the
traditional dichotomy. It was hypothesized that different types of reputations (such as “friendly”,
“dishonest”, and “aggressive”) would group together in categories beyond “positive” and
“negative.” Additionally, individuals with different life history strategies might find different
reputations important, because the reputations they find most important may help them get the
kinds of resources they need to attain their specific evolutionary goals. Therefore, it was also
predicted that the importance individuals place on different types of reputations would vary as a
function of life history strategy. Exploratory factor analysis identified a five factor structure for
reputations. Individuals also placed varying levels of importance on different types of
reputations, and found some reputations more important than others depending on their life
history strategy. This study demonstrates that reputational information is more nuanced than
previously thought and future research should consider that there may be more than just
“positive” and “negative” reputations in social interactions.

Last Hymn was created by the team of Tyler Pinho, Jefferson Le, and Curtis Spence with the desire to create an eccentric Role Playing Game focused on the exploration of a strange, dying world. Battles in the game are based off of rhythm games like Dance Dance Revolution using a procedural generation algorithm that makes every encounter unique. This is then complemented with the path system where each enemy has unique rhythm patterns to give them different types of combat opportunities. In Last Hymn, the player arrives on a train at the World's End Train Station where they are greeted by a mysterious figure and guided to the Forest where they witness the end of the world and find themselves back at the train station before they left for the Forest. With only a limited amount of time per cycle of the world, the player must constantly weigh the opportunity cost of each decision, and only with careful thought, conviction, and tenacity will the player find a conclusion from the never ending cycle of rebirth. Blending both Shinto architecture and modern elements, Last Hymn used a "fantasy-chic" aesthetic in order to provide memorable locations and dissonant imagery. As the player explores they will struggle against puzzles and dynamic, rhythm based combat while trying to unravel the mystery of the world's looping time. Last Hymn was designed to develop innovative and dynamic new solutions for combat, exploration, and mapping. From this project all three team members were able to grow their software development and game design skills, achieving goals like improved level design, improved asset pipelines while simultaneously aiming to craft an experience that will be unforgettable for players everywhere.

Although social cognitive deficits are considered a hallmark trait of schizophrenia, research on schizotypy and social cognition is inconsistent. The present study examines the associations among schizotypy, aberrant salience, and social cognition. Schizotypy and aberrant salience were assessed continuously using the Schizotypal Personality Questionnaire Brief Revised (SPQ-BR) and the Aberrant Salience Inventory (ASI). Social cognition was examined using The Awareness of Social Inference Test (TASIT), an audio-visual paradigm that taps into multiple domains of social cognition. Data from 849 undergraduate students was analyzed. Results indicated that schizotypy overall was not associated with social cognitive deficits. However, when schizotypy was analyzed dimensionally, positive schizotypy was associated with social cognitive impairments. Further, aberrant salience was revealed to be consistently associated with social cognitive impairments, except when positive schizotypy was included in the model. This suggests the possibility that positive schizotypy could mediate the association between aberrant salience and social cognition. Overall, this study highlights the importance of focusing on positive schizotypy and aberrant salience in future investigations of social cognitive difficulties in psychosis.

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.

The present study examines the role of uncertainty and how it relates to variables pertinent to student success such as anxiety, future self-identification, and academic self-efficacy. The present study consists of two parts. Part 1 of the study aims to address whether levels of perceived uncertainty predict levels of state-anxiety, future self-identification, academic self-efficacy, and perceived predictability. Part 2 of the study aims to test the efficacy of a web-based manipulation among a sample of first-year students at Arizona State University. The experimental manipulation utilizes elements of self-compassion to attempt to mitigate the effects of uncertainty and anxiety, and their negative effects on cognitive performance. Additionally, the manipulation aims to increase academic self-efficacy and future self-identification. The study was administered online and consisted of 170 participants. For part one of the study, all participants were used in the correlational analyses. For part two of the study, the participants were randomly divided into two groups, the control condition and the self-compassion condition. As hypothesized, findings show that uncertainty of one’s future predicted (a) higher state-anxiety, (b) weaker future self-identification(b) less perceived predictability of the future, and (c) less academic self-efficacy. Analysis also revealed that perceived uncertainty and anxiety predicted a higher level of cognitive interference as evidenced by the number of errors on the Stroop Task. Nevertheless, the proposed manipulation did not demonstrate statistically significant effects to reduce students’ perceived uncertainty and anxiety about their future. In conclusion, the present findings support the theorized relationships between uncertainty, anxiety, future self-identification, self-efficacy, and cognitive performance. Implications, limitations and future directions of this research are discussed.

The body tilt illusion relates to one’s exaggerated perception of body tilt angle in comparison to reality. People tend to overestimate this illusion and feel that they are tilted at 45º when they are tilted less than 45º in reality. This illusion increases with lack of sensory cues and decreases when sensory cues are added. In the present study, distortion in the perception of body tilt was examined as a function of center of mass. There are gender differences in regards to where one’s center of mass lies on their body, with females having a lower center of mass on average compared to males (Elert, 2005). We used a human-sized 3D gyroscope to test participants’ experience of the body tilt illusion. The findings support that perception of body tilt is multisensory and that visual information as well as the tilting plane affects the magnitude of the illusion. This is consistent with the illusion being functional for helping people keep their balance. Yet, we did not find significant differences in the size of the illusion due to differences in center of mass. The pattern of findings supports that the body tilt illusion is relatively universal, and likely functional, but does not vary much due to individual body shape differences like center of mass.

Introduction: Edibles, THC-infused food products, are a popular type of cannabis. However, there is limited research on how acute effects of edibles differ from more traditional cannabis types, such as smoked flower (e.g., dried bud). The current study examined the subjective response of cannabis between smoked flower and edibles using a two-week long ecological momentary assessment (EMA). Sex differences were also examined.Method: Individuals (n=101) using both edibles and flower at least once weekly completed a cannabis report within 30 minutes (T1) of first cannabis use each day as well as two follow-up reports sent 1.5 (T2) and 3 hours (T3) after initial use. Participants additionally completed assessments throughout the day for fourteen consecutive days to examine daily affect. Multi-level models examined whether overall high, low-arousal negative effects, high-arousal negative effects, and general positive effects differed by edibles and flower. Given time differences in effects between cannabis types, subjective effects were examined at T1, T2, and T3, as well as for the peak effects across the three-hour time window. Covariates included demographics, variant- and invariant- cannabis use characteristics, and daily affect. Results: At T1, edibles produced lesser positive effects (b=-0.60, S.E.=0.16, p=0.001) and overall high (b=-2.00, S.E.=0.27, p<0.001) relative to flower. At T2, edibles produced greater positive effects (b=0.52, S.E.=0.21, p=0.01) relative to flower. At T3, edibles produced greater low-arousal negative effects (b=0.63, S.E.=0.23, p=0.01) relative to flower. Edibles produced greater peak low-arousal effects relative to flower (b=0.59, S.E.=0.21, p=0.01), With respect to sex differences, there was an interaction between sex and cannabis type at T1 for positive effects (b=-0.99, S.E.=0.31, p=0.001), such that males reported greater positive effects for flower. Males additionally reported lesser low-arousal effects at T1 (b=-0.60, S.E.=0.30, p=0.05) and greater overall high at T3 relative to females (b=1.24, S.E.=0.56, p=0.03). Discussion: Smoked flower produced greater effects immediately and edibles produced greater delayed effects. Edibles appear to have greater peak levels of low-arousal effects (e.g., sluggish, drowsy, slow) relative to smoked flower. Males may be more sensitive to the rewarding effects of cannabis, particularly when smoking flower.

Anxiety disorder diagnosis is a risk factor for alcohol use disorders (AUDs), but mechanisms of risk are not well understood. Studies show that anxious individuals receive greater negative reinforcement from alcohol when consumed prior to a stressor, but few studies have examined whether anxious individuals receive greater negative (or positive) reinforcement from alcohol in a general drinking context (i.e., no imminent stressor). Previous studies have also failed to examine possible moderating effects of specific drinking contexts (e.g., drinking in a group or alone). Finally, no studies have investigated mediating variables that might explain the relationship between anxiety and reinforcement from alcohol, such as physiological response to alcohol (e.g., cortisol response). Data for this study were drawn from a large alcohol administration study (N = 447) wherein participants were randomized to receive alcohol (target peak BAC: .08 g%) or placebo in one of four contexts: group simulated bar, solitary simulated bar, group sterile laboratory, solitary sterile laboratory. It was hypothesized that anxiety would be associated with positive subjective response (SR) under alcohol (above and beyond placebo), indicating stronger reinforcement from alcohol. It was also hypothesized that social and physical drinking context would moderate this relationship. Finally, it was hypothesized that anxiety would be associated with a blunted cortisol response to alcohol (compared to placebo) and this blunted cortisol response would be associated with stronger positive SR and weaker negative SR. Results showed that anxiety was not associated with positive SR in the full sample, but drinking context did moderate the anxiety/SR relationship in most cases (e.g., anxiety was significantly associated with positive SR (stimulation) under placebo in solitary contexts only). There was no evidence that cortisol response to alcohol mediated the relationship between anxiety and SR. This study provides evidence that anxious drinkers expect stronger positive reinforcement from alcohol in solitary contexts, which has implications for intervention (e.g., modification of existing interventions like expectancy challenge). Null findings regarding cortisol response suggest alcohol’s effect on cortisol response to stress (rather than cortisol response to alcohol consumption) may be more relevant for SR and drinking behavior among anxious individuals.
