Description
One of the nation's most pressing health related issues is that of healthy diet and proper nutrition. Because much research has shown that many Americans are in poor health or are at risk to become so due to poor diet and nutrition, understanding the psychological factors of a healthy diet or lack thereof is of the utmost importance. In order to understand the adoption and maintenance of health related behaviors, the link between intentions and behaviors must be evaluated. Of current health behavior models, the model utilized in this study was the Health Action Process Approach model (HAPA), which addressed this "intention-behavior gap." The HAPA model proposes that planning is the key mediator of the link between intentions and behavior. The current research was performed in two stages. The first stage evaluated the psychosocial constructs of the HAPA model, and their predictive utility for current diet and the second stage evaluated a planning-based intervention that aimed to increase proper nutrition in college-aged women. All HAPA constructs were found to be significantly correlated with one another, and planning was found to significantly and fully mediate the link between intention and healthy diet. The intervention did not lead to an increase in healthy diet relative to a standard-of-care control, although all participants across conditions reported increased intention, self-efficacy, and healthy diet from pre-test to follow-up.

Description
Recent research on alcohol use among LGB young adults indicates that sexual minority youth are at increased risk relative to their heterosexual peers. One possible contributing factor is that religiosity fails to provide the significant protection for LGB youth that it has been demonstrated to provide in general population samples. Although recent studies provide some support for this hypothesis, there is little research seeking to understand the reasons that religiosity may fail to protect against heavy drinking among LGB youth. The current study attempted to address this gap by examining relations among religiosity, age of self-identification, and alcohol use in a sample of 103 young adults self identified as lesbian, gay, or bisexual. Using multiple regression, we found that religiosity had an indirect effect on alcohol use operating through age of identification as LGB. Higher religiosity was associated with a later age of self-identification, which in turn, predicted greater increases in alcohol use among LGB youth during the transition from high school through college. Exploratory analyses found that gender significantly moderated the influence of age of self-identification on alcohol use such that a later age of self-identification was a risk factor for increased drinking for women, but not for men. The findings have important implications for understanding complex relations between religiosity and alcohol use among LGB youth. In addition, the findings may inform the development of religious support groups for LGB youth that will allow them to experience the benefits of religious involvement that heterosexual youth experience.

Description
Humans require sufficient social understanding and connectedness to thrive (Baumeister & Leary, 1995). The current study evaluates the effectiveness of the Social Intelligence Institute's training program pilot. At a middle school in Phoenix, Arizona, students in a 7th and 8th grade class participated in this pilot program during the spring of 2013. Pre- and post-test questionnaires administered indicated changes in participants reported measures of Perspective Taking, Empathetic Concern, Interpersonal Expectations, and Relationship Self-Efficacy. The program consists of seven modules, each with several sessions, including instructional videos with reflection questions and class discussions. It was predicted that there would be a significant increase in mean scores for the dependent variables in the questionnaire mentioned above from the pre-test to the post-test. However, the null hypotheses were not rejected; statistical significance in t-tests of the measured variables were not met. Yet, the program was more effective for 8th graders than for 7th graders for Perspective Taking. This study of the SI pilot program demonstrates areas of improvement and provides support for wider implementation in the future.

Description
This study examined the relation between Religiosity (a motivational system) and Working Memory Capacity (a cognitive system) to determine how they interact to promote goal-directed behavior. Participants completed a religiosity questionnaire and engaged in a battery of tasks that were used to assess their Working Memory Capacity (WMC) and overall ability to maintain goal-directed behavior. The Stroop task was used to examine the participants' ability to maintain goals in the face of interference. It was predicted that religiosity and WMC would be inversely related and that when we controlled for religiosity, WMC would be the only significant predictor of Stroop performance. Furthermore, we hypothesized that religiosity and Stoop would be inversely related, whereas WMC and Stroop would be positively correlated with one another. Religiosity and Stroop performance were each divided into three different components. Religiosity was divided into: Intrinsic Motivation, Extrinsic Motivation, and CARMA. Stroop Performance was measured through Stroop Accuracy, the Stroop Effect, and Post-Error Slowing. The results of our study supported each of our hypotheses. These findings demonstrated that there is a cognitive process underlying motivational systems, such as religion, which affect an individual's ability to sustain goal-directed behavior.

Description
Increasing vegetable consumption among the adult population is a major goal, as the health benefits of vegetables can decrease one's risk of heart disease, cancer, diabetes, and obesity. The current study examined a potential strategy to increase consumption of vegetables by pairing them with a dip and a TV distraction. Based upon results of previous, similar research studies (Blass et al., 2006; Fisher et al., 2012; Johnston et al., 2012; Mittal, Stevenson, Oaten, & Miller, 2011), we hypothesized that eating vegetables with dip or while distracted with a television sitcom would result in increased consumption. We also hypothesized that both dip and a distraction together will synergistically increase vegetable consumption. A total of 126 college students were assigned to one of four conditions: eating vegetables with dip, with dip and a television distractor, with only a television distractor, or without either dip or a television distractor. While television had no significant influence on vegetable consumption, pairing vegetables with a dip significantly increased consumption of vegetables. Pairing vegetables with a dip may prove to be an effective strategy for increasing vegetable intake in the adult population.

The media often portrays professional basketball players as narcissistic, entitled and selfish, but are these portrayals accurate? After all, basketball is a team sport and team sport research indicates that players are more altruistic and selfless. This study proposes a way to assess narcissism and altruism through observable behaviors from all the active players in the NBA.

Description
Sport is a widespread phenomenon across human cultures and history. Unfortunately, positive emotions in sport have been long vaguely characterized as happy or pleasant, or ignored altogether. Recent emotion research has taken a differentiated approach, however, suggesting there are distinct positive emotions with diverse implications for behavior. The present study applied this evolutionarily informed approach in the context of sport to examine which positive emotions are associated with play. It was hypothesized that pride, amusement, and enthusiasm, but not contentment or awe, would increase in Ultimate Frisbee players during a practice scrimmage. Further, it was hypothesized that increases in pride and amusement during practice would be differentially associated with sport outcomes, including performance (scores, assists, and defenses), subjective social connectedness, attributions of success, and attitudes toward the importance of practice. It was found that all positive emotions decreased during practice. It was also found that increases in pride were associated with more scores and greater social connectedness, whereas increases in amusement were associated with more assists. The present study was one of the first to examine change in positive emotions during play and to relate them to specific performance outcomes. Future studies should expand to determine which came first: emotion or performance.

Description
Realistic or unrealistic expectations are formed prior to having the child and can affect the relationship quality of the mother and infant at 3 months and the reported maternal stress levels at 6 months. Violated expectations can either positively or negatively change the course of the relationship quality and stress levels. To test the nature of such relations, a series of regression analyses and one-way ANOVAs examined the associations between maternal expectations (and violations of maternal expectations) and maternal stress at 6 months. Further, mother-infant relationship quality was examined as a possible mediator of this association. Results indicated that prenatal maternal expectations and maternal expectations at 6 weeks were significantly correlated with maternal stress at 6 months. The higher the maternal expectations, the lower the maternal stress. There were no significant relations discovered between maternal expectations and relationship quality or relationship quality and maternal stress. Relationship quality does not mediate the relation of maternal expectations (or violated maternal expectations) and maternal stress. Violated maternal expectations that moved towards realistic did achieve better relationship quality scores, but maternal stress scores stayed consistent no matter the direction of the change.

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
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.
