Key Features to Alert Providers to Assess for ASD in Globally Developmentally Delayed Toddlers

Social Affect	Restricted and Repetitive Behaviors
Infrequently directs vocalizations to provider or parent	Clear demonstrations of interests in sensory aspects of objects or environment (e.g., sniffing, licking, or repeatedly touching a specific texture; bringing objects up to eye level and peering at them)
Absence of consistent eye gaze during social interaction to modulate interaction (e.g., looking at provider when provider speaks to child, looks and points to item to request)	Repetitive movements of hands or fingers (e.g., tensing, finger flicking)
Lack of response to name when called by provider or parent	Restricted interests (e.g., only wants to play with one part of toy or object, such as spinning wheels of car) or stereotyped behaviors (e.g., lining up toys; insistence on other people performing a ritual) that cause distress if interrupted
Diminished shared enjoyment during play (e.g., not smiling, laughing. Or looking at provider/parent when tickled or playing peekaboo)
Absence of eye contact and another behavior (e.g., vocalization, handing object to provider/parent, facial expression) to request specific object (e.g., snack or toy) from provider or parent
Does not make eye contact with provider or parent if provider or parent pretends to be unable to open toy or snack container
Absence of behaviors to draw another person’s attention to an object that is out of reach (e.g., a toy across the room)
