Description

It is possible that autistic people find it easier to socialize within their own peer group (Beaupré & Hess, 2006), by recognizing socio-emotional nonverbal cues, due to a shared neurodivergence. To assess this, it would be helpful for researchers to have a database of emotional stimuli, validated for use with autistic individuals. Unfortunately, this does not exist. This current study’s objective is to create such a database that evokes natural emotion, rated by autistic individuals to be used in future research. All participants completed the Alexithymia Scale (TAS-20) which measures the participants’ ability to identify and describe their own emotions (Taylor et al., 2003), the Marlowe-Crowne Social Desirability Scale to ensure participants are answering authentically (Crowne & Marlowe, 1960), and the SRS-2 scale which indicates the participants’ social ability (Constantino et al., 2003). Participants watched 45 short videos (Ack Baraly, 2020) chosen to elicit either a positive, negative, or neutral reaction. After each video, participants reported emotional responses using the Affect, Anxiety, Pride, and Energy (AAPE) scale (Riccio, 2020). Preliminary analysis included 70 participants. 41% of participants scored above the SRS-2 clinical cutoff. Participants' videos were then clustered using k-means, based on the ratings and SRS-2 scores. Results reveal both overlap and nonintersecting responses between participants above and below the SRS-2 cutoff..The next step is to use hierarchical analysis within each k-means cluster, allowing exploration of the variability. Further insight on these differences will allow production of a video database labeled with the emotions they evoke in autistic participants.
