192The sensorimotor EEG mu rhythm, a measure of the neural mirroring system, may offer insight into language production during infancy. This study investigates whether 12-month-olds' mu rhythm desynchronization (MRD) during action observation is related to parent-reported vocabulary production from 12-24 months. We hypothesize that greater MRD will be associated with higher productive vocabulary, particularly for nouns. These findings may provide insight into early motor-language integration and the role of the mirroring system in language development.POSTER 64UNINFORMED CONSENT?: PARTICIPANT COMPREHENSION OF CONSENT FORMSKAITLYN CARR (SAINT JOSEPH'S UNIVERSITY), DEBORAH WARD (SAINT JOSEPH'S UNIVERSITY), CLARE CONRY-MURRAY (JOHNS HOPKINS UNIVERSITY) Although research participation requires informed consent, participants may not fully understand the content of consent forms. Participants (N=228) were randomly assigned to read one pair of consent forms, out of eight total variations. Forms varied in terms of reading level, format, and interactivity. Use of interactive questions improved comprehension, but lowered reading level and use of bullet-point formatting did not. Therefore, use of interactive questions in consent forms may improve participant comprehension of studies.POSTER 65USING AI TO GENERATE PERSONALITY TESTS: AN EXPLORATORY STUDYHANNAH BURGOYNE (MANHATTAN UNIVERSITY), MADELINE BRAUN (MANHATTAN UNIVERSITY), ARNO KOLZ (MANHATTAN UNIVERSITY) The purpose of this study was to see if two popular AI models, ChatGPT and Claude, could generate reliable tests of the Big-5 personality traits without inappropriately copying popular published scales. Both models were able to generate sufficiently unique items after only three prompt interactions. ChatGPT succeeded in producing 5 reliable scales, while Claude only produced one. The items generated by ChatGPT, but not Claude, demonstrated high factor loadings on the appropriate scales.POSTER 66USING SOCIAL NORMS MARKETING TO REDUCE STIGMATIZATION OF MENTAL HEALTH AND SELFDISCLOSUREGABRIELLE JAMIESON (UNIVERSITY OF SCRANTON), JESSICA NOLAN (UNIVERSITY OF SCRANTON) The present study examined the use of social norms marketing to reduce mental health stigma (MHS) and increase positive attitudes towards self-disclosure. Participants were informed that either 22% or 70% of adults experience mental health struggles. Afterreading a vignette describing someone self-disclosing mental illness, participants completed MHS and selfdisclosure attitude scales. The manipulation impacted perceived prevalence of mental illness but failed to influence stigma or self-disclosure attitudes, potentially indicating increasing public mental health awareness.POSTER 67VARIETY IS THE SPICE OF LIFE: EFFECTS OF LIGHTNESS HETEROGENEITYJESSICA COYLE (MANHATTAN COLLEGE), MARIA PERRINO (MANHATTAN UNIVERSITY), JULIA CIAMPA (MANHATTAN UNIVERSITY), JAY FRIEDENBERG (MANHATTAN UNIVERSITY) This study used varying ratios of black-and-white elements in a circular dot pattern to test for the effects of variety on ratings of beauty and interest. Perceived beauty was greatest for completely homogenous patterns, while interest ratings were higher for heterogeneous ones.POSTER 68WEIGHT BIAS AMONG COUNSELING TRAINEESLEAH WARDWELL (MILLERSVILLE UNIVERSITY OF PENNSYLVANIA), RACHEL MACINTYRE (MILLERSVILLE UNIVERSITY OF PENNSYLVANIA), SHAUN COOK (MILLERSVILLE UNIVERSITY OF PENNSYLVANIA), ELIZABETH THYRUM (MILLERSVILLE UNIVERSITY OF PENNSYLVANIA) Weight bias can negatively impact the treatment of overweight individuals. Graduate students and clinicians completed an online survey with a case study, photograph, and questionnaires. It was hypothesized that participants who received the \ photograph would display more tentativeness and prescribe more eating-based symptoms and diagnoses than participants who received the \no significant differences between groups. Future directions are discussed to improve research on weight bias in therapeutic settings.192
