Often learning new skills, such as how to throw a basketball or how to play the piano, are better accomplished practicing with another than from self-practice. Why? We propose that during joint action, partners learn to adjust their behavior to each other. For example, when dancing with a partner, we must adjust the timing, the force, and the spatial locations of movements to those of the partner. We call these adjustments a joint body schema (JBS). That is, the locations of our own effectors and our own movements are adapted by interaction with the partner. Furthermore, we propose that after a JBS is established, learning new motor skills can be enhanced by the learner's attunement to the specifics of the partner's actions. We test this proposal by having partners engage in a motor task requiring cooperation (to develop the JBS). Then we determined whether a) the JBS enhances the coordination on an unrelated task, and b) whether the JBS enhances the learning of a new motor skill. In fact, participants who established a JBS showed stronger coordination with a partner and better motor learning from the partner than did control participants. Several applications of this finding are discussed.

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
The Latino population is the fastest growing minority group in the United States (U.S Census Bureau, 2003). Such a rapidly changing demographic stresses the importance of implementing strategies into the community social framework to accommodate for cultural and language differences. This research paper seeks to answer: what factors influence the sense of community among Latino families in Phoenix? The following questions will help to assess the dynamic relationship between sense of community and literacy 1) what is the perceived importance of literacy among Latino families living in Phoenix? 2) How is language development reflected among the family dynamics within a predominantly collectivist culture? It is hypothesized that both collectivism and literacy are the main influences on sense of community among this population.

Description
This project, which consists of a review article and an applied creative project, proposes mirror neurons as being a physiological mechanism for motor imagery. The review article highlights similarities between motor imagery research and research on mirror neurons. The research is roughly divided into three types of studies: neuroimaging studies, transcranial magnetic stimulation (TMS) and electromyography (EMG) studies, and electroencephalography (EEG) studies. The review also discusses the associative hypothesis of mirror neuron origin as support for the hypothesis and concludes with an assessment of conflicting research and the limitations of the hypothesis. The applied creative project is an instructional brochure, aimed at anyone who teaches motor skills, such as dance teachers or sports coaches. The brochure takes the academic content of the review and presents it in a visually pleasing, reader-friendly fashion in an effort to educate the intended audience and make the research more accessible. The brochure also prescribes research-based suggestions for how to use motor imagery during teaching sessions and how to get the best benefits from it.

Description
Sleep is an extremely important component of living a healthy life than can impact development and behavior starting in childhood. We expanded on past research regarding this topic to determine the role of childhood sleep and the onset of problem behaviors (externalizing and internalizing behaviors) among a sample of school-aged children. We predicted that lower sleep duration, decreased sleep efficiency, and prolonged sleep latency along with negative sleep habits would be associated with problem behaviors. Our sample was made up of 381 school-aged children (M = 8.49 years old, 49.6% female, 56% Caucasian) who were recruited through the Arizona Twin Study when the children were 12 months old. Mixed-model regressions included sex, socioeconomic status, and zygosity as covariates. Correlations and mixed-model regressions showed a significant relationship between negative sleep habits and problem behaviors (both externalizing and internalizing). Our results revealed that those who experience higher amounts of parent-reported negative sleep habits also demonstrate externalizing behaviors (aggression) and internalizing behaviors (anxiety). The findings in the current study are consistent with past research on this topic and suggest that poor sleep impacts daytime functioning and behavior.

Description
Recent evidence suggests that youth from affluent and upper-middle-class, white collar families are at high risk for maladaptive behaviors, such as aggression, rule breaking, and substance use. A major hypothesized underlying factor is lax parental discipline that involves low repercussions for errant behaviors such as substance use—also known as perceived parents’ “containment” of such behaviors. In this study, the focus is on multiple dimensions of perceived containment among parents and school authorities, in relation to both externalizing problems and drug use behaviors. These associations are examined in four different schools: two boarding schools and two day schools. Results show much stronger links with maladjustment for perceived containment by parents as opposed to perceived containment by school. The largest significant effects within the containment indices were found to be between parent containment of drug use and the levels of substance use behaviors reported by students. These effects were found across gender and all schools, indicating robust links. Overall, the most robust index studied was the perceived parental monitoring variables; monitoring effects were stronger than effects from any containment variables. Students who perceived the highest levels of parental monitoring exhibited the least amount of externalizing behaviors across all schools and genders. A possible explanation includes students perceiving that their parents monitor their behavior due to caring on the behalf of the parent, which then leads to fewer externalizing outcomes. These results suggest that the most effective means of decreasing substance use levels seem to lie within the parents of the students and not the schools.

Description
Simulation theory states that text comprehension is achieved by simulating (or imagining) text content using motor, perceptual, and emotional systems. Hence, motor skill should correlate with comprehension skill. In fact, previous research has linked fine motor skills (FMS) with word processing and mathematical skills. I predicted a positive relationship between FMS and reading comprehension. Children enrolled in a reading comprehension intervention were assessed on FMS using the Movement ABC-2. There was a significant correlation between FMS and comprehension of narrative texts, but contrary to the prediction, the correlation was negative. Also unexpected, the control condition performed better on comprehension questions than the intervention conditions. To try to understand these results, we examined the time each child took to answer the comprehension questions. Many children answered the questions quickly, and average time to answer the questions was strongly correlated with comprehension scores. Children may have been answering questions quickly (and randomly) in order to advance to the next story. Nonetheless, the data do not support a relationship between FMS and reading comprehension.

Description
Introduction: Depression is one of the most prevalent mental illnesses in the United States, and is characterized by feeling sad or empty most of the day, nearly every day (American Psychiatric Association, 2013). The experience of childhood trauma is one of many factors that may lead to depression, while trauma can also yield other adverse life outcomes, such as alcohol-related consequences (Felitti et al., 2001; Neumann, 2017). One of the specific aims of this investigation was to examine the direct influences of childhood trauma on depression. We also examined selected direct and indirect influences of childhood trauma on drinking outcomes through the potential mediating mechanism of depression. We examined three distinct drinking outcomes, 1) impaired control over drinking (i.e. the inability to stop drinking when intended), 2) heavy episodic drinking (four or more drinks on one occasion for men, four or more for women), and 3) alcohol-related problems. Methods: A survey was administered to 940 (466 women, 474 men) university students. Structural equation modeling was used to examine the data. Potential two- and three-path mediated effects were examined with the bias corrected bootstrap technique in Mplus (MacKinnon, 2008). Results: Emotional abuse was found to be positively associated with depression. In contrast, having an emotionally supportive family was found to be negatively associated with depression. Congruent with the Self-Medication Hypothesis, depression was found to be positively associated with impaired control over drinking. Physical neglect was found to be positively associated with impaired control. Lastly, emotional abuse was found to be indirectly linked to increased heavy episodic drinking and alcohol-related problems through depression and impaired control.

Description
Fast mapping is the initial link infants make between a word and its referent, and it is crucial to later processes of learning the meanings of words. Despite the importance of fast mapping, previous research has suggested that fast mapping is fragile, with infants being unable to retain words learned through fast mapping longer than five minutes. The current study tested the robustness of fast mapping by imposing task irrelevant interruptions on a fast mapping task. Forty-seven infants (14.7 \u2014 17.4 months old) were assigned to a No Interruption condition, a Posture Interruption condition, or a Visual Interruption condition, and they performed a fast mapping task in which a novel object was named in one trial. Videos of the infants were coded for accuracy of fast mapping and for attentional behaviors (looking behavior) during the task. We found that infants did not learn novel word-object pairings when interrupted, demonstrating that infants' fast mapping abilities are easily disrupted. Overall, there was no evidence that looking behaviors were affected by interruptions, or that they were correlated with accuracy. These findings suggest that fast mapping is fragile in young infants, and further research is required to determine the mechanisms for infant learning, and how infants transition from fast to slow mapping processes.

Description
Academic success in childhood is crucial for later academic, occupational, and life success (Heckman, 2006; Kuncel, Hezlett, & Ones, 2004; Spengler, Brunner, Damian, Lüdtke, Martin, & Roberts, 2015). Recent research suggests sleep is important for academic success but lacks objective measures of sleep (Buckhalt, El-Sheikh, Keller, & Kelly, 2009; Curcio, Ferrara, & De Gennaro, 2006; Dewald, Meijer, Oort, Kerkhof, & Bögels, 2010; Philbrook, Hinnant, Elmore-Staton, Buckhalt, & El-Sheikh, 2017). The purpose of this study was to examine the relations between sleep and academic success among children through objective measures of sleep in order to expand on the literature. Our sample consisted of 381 twins (50.4% male; 56% Caucasian; 36.5% same sex dizygotic) participating in an 8-year assessment from a longitudinal twin study. Actigraphy was used to assess sleep while various measures were used to assess academic success. A series of mixed model regressions were used to test the main predictions, with family entered as a random effect. Sex, age, Hispanic, SES, and zygosity were controlled for. Significant negative relations were revealed between sleep latency and reading and sleep latency and school liking. Additionally, SES was the most consistent significant positive predictor of our measures of academic success. These results suggest sleep and effects of SES should be considered when developing ways to help children’s school performance.
