Sydney Segal is a doctoral student in Clinical Psychology whose research centers on early development, attachment, and the role of communication within caregiver–child relationships. She is the former lab manager of the Human Language & Development Lab and also a member of the Center for Attachment Research. Within the Human Language and Development Lab, Sydney investigates nonverbal communication among Tseltal Maya mother–infant dyads, with a particular focus on breastfeeding as a contributor to attachment formation in cross-cultural contexts. Within the Center for Attachment Research, she examines children's understanding of parental technoference—technology-based interruptions to parent–child interactions—using play- and language-based measures, exploring how parental device use and limit-setting shape children's device regulation and attachment representations. Sydney formerly worked as an actor, and she also enjoys hiking and taking long walks around the city.
