58parameters, with findings showing no significant correlation between sleep quality and decision-making.POSTER 10AFFECTIVE DYNAMICS: UNDERSTANDING DAILY AFFECTIVE EXPERIENCES OF BLACK AND LATINAE INDIVIDUALSCHELSEA LAMAR (SAINT JOHN'S UNIVERSITY), LINDSAY BONN (SAINT JOHN'S UNIVERSITY), SOPHIA RIVERA (SAINT JOHN'S UNIVERSITY), MALAIKA SHEIKH (SAINT JOHN'S UNIVERSITY), BRIANNA MANNINO (SAINT JOHN'S UNIVERSITY), JOSHUA CASTELLANOS (SAINT JOHN'S UNIVERSITY), ANACHKHAIDZE (SAINT JOHN'S UNIVERSITY), MARCUS JOYNER (SAINT JOHN'S UNIVERSITY), ELIZABETH BRONDOLO (SAINT JOHN'S UNIVERSITY) This study examined the association of ethnicity and ethnic identity on affective dynamics%u2014patterns of emotional experience over time%u2014using data from Black and Latinae adults in New York City. The analyses found that Latinae participants showed greater emotional polarity in anger compared to Black participants. These findings highlight the complex interplay among ethnicity, ethnic identity and emotional experiences.POSTER 11AGE AS A FACTOR FOR STRUCTURAL NEUROIMAGING SCAN QUALITY IN ARFIDJACQUELINE ALTMAN (MGH), STEFANIA YEE (MGH), LUKE ALEXANDER DYSART (MGH), SIDDARTH SEENIVASA (MGH), LILIAN PALMER (MGH), JENNIFER J. THOMAS (MGH), ELIZABETH A. LAWSON (MGH), KAMRYN T. EDDY (MGH), MAREK R. KUBICKI (MGH), LAUREN BREITHAUPT (MGH), MARY C. CATANESE (MGH) Understanding potential impacts of age on magnetic resonance imaging (MRI) image quality is critical. In an MRI study in Avoidant Restrictive Food Intake Disorder (ARFID), we examine age in relation to image quality, comparing ARFID (n=250) and controls (n=100), aged 9-45 years. In a subset, aged 9-23, a main effect of age on image quality was observed across groups aged 9-15 years. This work will inform neuroimaging studies with young participants, including ARFID.POSTER 12ALCOHOL USE DISORDER AND PREDICTORS OF FAMILY RESILIENCEWILLIAM ECKERT (PENN STATE LEHIGH VALLEY A CAMPUS OF THE PENNSYLVANIA STATE UNIVERSITY), DAVID LIVERT (PENN STATE LEHIGH VALLEY A CAMPUS OF THE PENNSYLVANIA STATE UNIVERSITY) The study examines predictors of resilience in households that include and individual with AUD. Two phases of the research involve 1) a survey of Penn State students that identifies AUD-member households and assess basic mental health status and interpersonal relationships and 2) a follow-up questionnaire distributed to AUD-household members other than the student.POSTER 13ALPHA POWER AND 1/F APERIODIC COMPONENTS PREDICT PERFORMANCE IN COVERT ATTENTION MODELSDEANNA SINCLAIR (SWARTHMORE COLLEGE), BRIAN METZGER (SWARTHMORE COLLEGE) EEG alpha-band power is a predictor of task performance across several cognitive domains. Recently, 1/F slope has emerged as a predictor/correlate of cognition. The present research seeks to determine whether alpha power and 1/F slope from resting-state EEG subsequently predict performance on a covert attention cueing task. AIC analyses will be used to compare predictive models that include alpha power and 1/F slope against models that contain either alpha or 1/F.POSTER 14AN EVALUATION OF STRESSORS EXPERIENCED BY MINORITIZED FIRST-YEAR COLLEGE STUDENTSCATALINA CRUZ (MILLERSVILLE UNIVERSITY), LAUREN REINHART (MILLERSVILLE UNIVERSITY), KARENA RUSH (MILLERSVILLE UNIVERSITY), SARAH BIRCH (ST. JOSEPH'S UNIVERSITY), CIERRA STRAWBRIDGE (MILLERSVILLE UNIVERSITY), DEBRA VREDENBURG-RUDY (MILLERSVILLE UNIVERSITY) Acclimating to college during the first year can be challenging. Many students report increases in stress with students with minoritized identities at an even greater risk (McGuinness & Nordstokke, 2023). The purpose of the current study was to examine thedifference between stressors reported by first-year students from minoritize groups compared to students from majority groups. The findings from this study are discussed as well as variables to consider for enhancing an inclusive classroom environment.58
