5SARA DINTIMAN (LEBANON VALLEY COLLEGE), LYDIA CRESPO (LEBANON VALLEY COLLEGE), EMMA RJEPAJ (LEBANON VALLEY COLLEGE), ALEXANDRA WASKO (LEBANON VALLEY COLLEGE), RACHEL ALBERT (LEBANON VALLEY COLLEGE) When infants babble, caregivers implicitly interpret the vocal maturity of the vocalization before deciding whether and how to respond. In this study, we asked whether infants' gaze while vocalizing actually shifts inexperienced caregivers' perceptions of vocal maturity. Students completed an experiment in which they rated the speech quality of examples of infant vocalizations manipulated for gaze and vocal quality. Our poster highlights the impact of multi-modal cues and caregiving experience on caregivers' perceptions of vocalizations.POSTER 20EARLY MEASURES OF INFANT ATTENTION AS A PREDICTOR OF TODDLER SOCIO-EMOTIONAL SKILLSSASHA ANDREWS (NEW YORK UNIVERSITY), DENISE WERCHAN (NYU LANGONE MEDICAL CENTER: NYU LANGONE HEALTH), NATALIE BRITO (NEW YORK UNIVERSITY) Associations have been reported between measures of early attention and later socio-emotional outcomes. We examined how infant attention and maternal social support were associated with infant socio-emotional skills during toddlerhood. In a sample of 47 infants, we found that measures of infant attention captured remotely in the home were associated with parentreport measures of socio-emotional skills. Social support also had an impact on infant attention and BITSEA scores.POSTER 21EFFECTS OF ADHD ON INTELLIGENCE AND THE PROCESSING SPEED/ACCURACY TRADE-OFFTAYLOR PITT (WILLIAM PATERSON UNIVERSITY), SIDAL YURT (WILLIAM PATERSON UNIVERSITY), CAMERYN FREGLETTE (WILLIAM PATERSON UNIVERSITY), ANNA SANCILIO (WILLIAM PATERSON UNIVERSITY), BRUCE DIAMOND (WILLIAM PATERSON UNIVERSITY) This study examines the relationship between intelligence, processing speed, and the speed-accuracy trade-off in children with ADHD. Archival data from 50 participants (ages 8%u201316) revealed weak to moderate relationships between intelligence, processing speed, and accuracy, even when controlling for response rate. Preliminary analyses found minimal group differences, except for omission errors. Ongoing analyses will explore relationships between omission and commission errors and processing speed to further understand cognitive dynamics in this population.POSTER 22EFFECTS OF INFANT SLEEP AND MATERNAL STRESS ON SOCIOEMOTIONAL DEVELOPMENTRIYA GOKHALE (NEW YORK UNIVERSITY), NATALIE BRITO (NEW YORK UNIVERSITY), DENISE WERCHAN (NEW YORK UNIVERSITY), MORIAH THOMASON (NEW YORK UNIVERSITY) This study examines the relationship between infant sleep at 6 months and socioemotional outcomes at 12 months, as well as the moderating role of maternal stress. In a sample of 232 mother-infant pairs, shorter nighttime sleep was linked to greater socioemotional problems. Maternal stress exacerbated the negative effects of poor sleep on later socioemotional outcomes. These findings highlight the importance of addressing both infant sleep quality and maternal stress to support socioemotional development in childhood.POSTER 23EFFECTS OF REWARD ON PRESCHOOLERS' EXECUTIVE FUNCTIONS: EXPLORING SES AND REWARD RESPONSIVENESSLAUREN BRYANT (SACRED HEART UNIVERSITY), SIERRA DOUGHTY (SACRED HEART UNIVERSITY), ASHLEE GOJCAJ (SACRED HEART UNIVERSITY), CATHERINE PALOMBO (SACRED HEART UNIVERSITY), SIERRA SAILER (SACRED HEART UNIVERSITY), BRYNNE SMITH (SACRED HEART UNIVERSITY), KIMBERLY CUEVAS (UNIVERSITY OF CONNECTICUT) Modern perspectives characterize executive functions (EFs) as the assembly of control processes pursuant to a specific goal; this varies with numerous intersecting factors, such as motivation and socio-economic status (SES). Our previous work found that rewards slowed preschoolers' responses on a Stroop-like task while improving their accuracy; these latter findings were moderated by reward sensitivity. Our current work examines how these patterns may be further moderated by children's SES.POSTER 24ETHNIC DISCRIMINATION AND PARENTAL DEPRESSION: ASSOCIATIONS WITH TODDLER LANGUAGE IN LOW-INCOME FAMILIESPATRICIA SOTO (BOSTON UNIVERSITY), SHAINA BRADY (BOSTON UNIVERSITY), DIANA LOPERA PEREZ (BOSTON UNIVERSITY), SARAH WATAMURA 5Friday, March 7
