Active Learning and Community Engagement: Pedagogical Synergy through the "Mobile Neuroscience Lab" Project.

The Mobile Neuroscience Lab is a project that facilitates combined pedagogical strategies of active learning and neuroscience outreach as a service learning component of a physiological psychology course. The overall project goals were to improve science knowledge, foster oral communication, and encourage positive science attitudes and beliefs. Of these goals, positive science attitudes and beliefs were assessed. During active learning, university students completed hands-on activities corresponding to the physiological psychology course. Following, during the neuroscience outreach activity ("learning through teaching"), university students and middle school students engaged in small group activities (one university student to five middle school students) using the same hands-on activities. Assessment of the perceived benefit of the active learning showed that university and middle school students responded favorably to the hands-on activities. Students' science attitudes were also assessed (Hillman et al., 2016) using a pre-test, post-test design. Data showed that the neuroscience activity did not change middle school science attitudes and beliefs (p > .05), possibly as the science attitudes and beliefs were already positive (moderate to high) prior to the outreach activity. However, qualitative data showed that the aspect of the neuroscience outreach activity that most assisted the middle school students in their learning was seeing the brain, touching the brain, and social interaction with the university students. Overall, the pedagogical strategies of active learning, and "learning through teaching", were received with enthusiasm by university and secondary education students. Future studies will include classroom teachers' assessment of these hands-on activities.

Stress System Response and Decision Making in Heavy Episodic Users of Alcohol and Online Video Games.

Objective: Few empirical studies have addressed stress system response and subsequent decision making in problematic online video game players who also consume alcohol. Method: Participants were randomly assigned to either receive a psychosocial stressor, including evaluated public speaking and mental arithmetic, or control condition. Salivary cortisol, cardiovascular and subjective responses were collected. Following, decision making was assessed using the Iowa Gambling Task. Results: In this sample of moderate internet gamers (N = 71; 45 male, 16.9% meeting suggested DSM-5 criteria for internet gaming disorder), 53.52% met gender-specific cut-points for heavy episodic drinking. Overall, participants in the TSST condition demonstrated elevated systolic and diastolic blood pressure, self-reported anxiety, and negative affect (ps < .05). However, response to the TSST was varied, particularly in individuals reporting binge internet gaming (6 h or more consecutive use in the last 30 d) who did not display the expected decline in positive affect in response to the TSST (p = .02). Differences in greater advantageous decision making between heavy episodic internet gaming participants in the stress condition, versus those reading a travel magazine, were also noted. These differences were not significant in participants reporting an absence of heavy episodic gaming behavior. Conclusions: These findings support the continued study of individuals who engage in problematic internet gaming behavior, particularly those who engage in heavy episodic use of alcohol.

Web-Based Alcohol Intervention in First-Year College Students: Efficacy of Full-Program Administration Prior to Second Semester.

BACKGROUND: Commercially available, web-based interventions for the prevention of alcohol use are being adopted for universal use with first-year college students, yet few have received empirical evaluation. OBJECTIVES: This randomized controlled trial investigated the effectiveness of a novel, commercially available, personalized web-based alcohol intervention, Alcohol-Wise (version 4.0, 3rd Millennium Classrooms), on multiple measures of alcohol consumption, alcohol consequences, alcohol expectancies, academic achievement, and adaptation to college in first-year students. METHOD: Participants received Alcohol-Wise either prior to first semester or were waitlisted and received the intervention second semester. As longitudinal effectiveness was of interest, follow-up surveys were conducted 10 weeks (n = 76) and 24 weeks (n = 64) following the web-based alcohol intervention. RESULTS: Completion of Alcohol-Wise had effects on academic achievement. Specifically, at the 24 week follow-up, academic achievement was higher in participants who received the intervention first semester of their freshman year as compared to the waitlist control. The incremental rise in heavy episodic drinking during the first semester of college was also reduced in waitlisted participants by Alcohol-Wise administration prior to second semester. Conclusion/Importance: Implications for the timing of web-based alcohol interventions to include administration prior to both first and second semesters of the freshman year are discussed.

Feasibility and Acceptability of Using Ecological Momentary Assessment to Evaluate Alcohol Use with American Indian Women.

BACKGROUND: Ecological momentary assessments (EMA) are one way to collect timely and accurate alcohol use data, as they involve signaling participants via cell phones to report on daily behaviors in real-time and in a participant's natural environment. EMA has never been used with American Indian populations to evaluate alcohol consumption. The purpose of this project was to determine the feasibility and acceptability of EMA for American Indian women. METHODS: Eligible participants were American Indian women between the ages of 18 and 44 who were not pregnant and had consumed more than one drink within the past month. All participants received a TracFone and weekly automated messages. Self-reported measures of daily quantity and frequency of alcohol consumption, alcohol type, and context were assessed once per week for four weeks. Baseline measurements also included the Drinking Motives Questionnaire-Revised (DMQ-R) and the Interpersonal Support Evaluation List (ISEL). RESULTS: Fifteen participants were enrolled in the study. All but one participant completed all data collection time points, and drinking patterns were consistent across the study period. A total of 420 records were completed across 86 drinking days and 334 non-drinking days. Participants reported drinking an average of 5.7 days over the 30-day period and typically consumed 3.99 drinks per drinking occasion. Sixty-six percent of participants met gender-specific cut-points for heavy episodic drinking, with an average of 2.46 binge drinking occasions across the four week study period. CONCLUSIONS: This proof-of-concept project showed that EMA was both feasible and acceptable for collecting alcohol data from American Indian women. Additional studies are necessary to fully implement EMA with American Indian women to better understand the drinking motives, contexts, patterns, and risk factors in this population.

Neonatal ethanol and nicotine exposure causes locomotor activity changes in preweanling animals.

Sprague-Dawley rats were used to investigate the effects of neonatal ethanol (ETOH) and nicotine (NIC) exposure on activity levels in preweanling offspring. Male and female pups received daily oral intubations of ethanol ((ETOH) 5 g/kg/day), nicotine ((NIC) 12 mg/kg/day), ethanol and nicotine ((ETOH+NIC) 5 g/kg/day+12 mg/kg/day) or isocaloric maltose (control) on either postnatal days (PND) 1-7 or PND 8-14. A non-treated control group was also included. Peak blood ethanol concentrations (BECs) measured in a separate subset of animals ranged from 167 and 344 mg/dl depending upon neonatal treatment and period of exposure. Subjects were tested in an open field apparatus on PND 19-21. Animals exposed to ETOH or ETOH+NIC on PND 1-7 were hyperactive relative to the other treatment groups. In contrast, animals exposed to NIC or ETOH+NIC during PND 8-14 were hypoactive relative to other treatment groups. Males appeared more sensitive than females on measures of anxiety (distance traveled in the center of the open field) but this also varied dependent on neonatal treatment and period of exposure. These findings suggest that the third trimester is a critical period for ETOH and NIC effects on offspring activity although the pattern of effects on activity are different depending on when drug exposure occurred during the neonatal period.
