Early Signs of Autism Video Tutorial | Kennedy Krieger Institute

Main summary

Key takeaways

Educational

Main ideas and lessons conveyed

  • Purpose of the tutorial: To show early signs of autism spectrum disorders (ASD) by comparing pairs of videos of one-year-olds:

    • In each pair, the first child shows typical (neurotypical) development
    • The second child shows early signs of ASD

  • Core ASD-related developmental features are grouped into three main categories:

    1. Effective communication and sharing enjoyment
    2. Making social connections
    3. (Introduced as the one they “will begin seeing”) Play / social opportunity through play

  • Key message about ASD progression:

    • Signs are not temporary; they persist over time.
    • The earliest signs can be subtle and often become more noticeable in the 2nd and 3rd year of life.

  • Diagnosis guidance:

    • An ASD diagnosis should be made by one or more experts who:
      • Collect a thorough developmental history
      • Directly assess the child’s abilities
      • Conduct a medical exam

What the video shows (by scenario)

1) 19-month-olds — Social opportunity through play

Neurotypical example (no ASD signs)

  • Engages with toys (balls) and includes another person in play quickly.
  • Uses pretend play (balls as food) and offers the item to the other person.
  • Understands that objects and actions fit together in a meaningful routine (food/spoons/plates/eating).
  • Maintains awareness of others nearby.
  • Shares excitement with eye contact and smiling.
  • Links play and language to the other person’s comment (e.g., “food is hot”).
  • Imitates the other person’s actions within pretend play (e.g., pretend lipstick), showing learning through social interaction and synchronizing actions with others.

ASD signs example (19 months)

  • Shows intense interest in a specific toy (phone).
  • Does not share enjoyment of the toy with others:
    • Limited/no looking toward others and smiling.
  • Uses the toy in a restricted way (phone to ear) but does not show creative/interactive play.
  • Does not respond when their name is called.
  • Does not offer the toy to others to take turns.
  • Even with distraction (together/tickle):
    • Appears to enjoy the tickling, but does not look at the mother
    • Does not build a social connection to continue the interaction
    • Does not communicate to keep the game going.

2) 14-month-olds — Mild motor delay vs ASD signs, and social communication

Neurotypical example (14 months; mild motor delay but not ASD)

  • Explores a new toy while staying aware of nearby people.
  • Checks in with mother behind them to ensure mother also sees the toy.
  • Responds to social cues:
    • Immediately looks at an object/sticker when the woman points to it.
    • Then looks to a previously pointed-at sticker.
  • Maintains the partner’s topic:
    • Points to the Tigger sticker, continuing the communication thread.
  • Demonstrates motivation for social engagement and the ability to communicate using:
    • Coordinated gaze
    • Vocalization
    • Gesture

ASD signs example (14 months)

  • Enjoys bubbles but displays reduced social sharing:
    • Flaps hands while enjoying bubbles (enjoyment expressed, but not socially shared).
    • Does not share enjoyment by looking at or responding to the man.
  • Does not respond to name.
  • Even if looking at the man’s pointed finger:
    • Does not follow the pointing gesture to locate the object of attention.
  • Communication/social direction is not effectively matched to the partner’s cue.

Neurotypical example (14 months; social sharing request is clear)

  • Enjoys exploring the toy while staying engaged with people nearby.
  • Tries to share enjoyment:
    • Turns to show the toy to her mother.
    • Then shares with a lady across from her using gaze and smile.
  • When needing help, she makes a clear and effective request using:
    • Coordinated eye contact
    • Gesture
    • Vocalization
  • Demonstrates that the presence of a helpful partner is understood and used appropriately.

ASD signs example (14 months)

  • Attention becomes very focused on the toy to the point of reduced interaction:
    • Does not interact with people nearby.
    • Does not share attention.
  • Unusual exploration:
    • Drops the toy and watches it move, repeatedly focusing on the object’s motion.
  • Reduced help-seeking communication:
    • No eye contact, vocalization, or gestures to ask for help.
    • Body/mouth tensing in an unusual way.
  • Shows limited understanding of others’ social meaning:
    • Does not seem to realize the woman’s gesture is an offer of help.
    • Does not check in with mother or the lady to see whether they are paying attention.

Overall takeaway (explicit conclusions)

  • ASD affects multiple areas, especially social and communication skills.
  • Children with ASD often show:
    • Unusually intense interests in certain objects/sensory experiences
    • Repetitive behaviors (e.g., repeated patterns of play/exploration)
  • Early signs tend to persist, and earlier subtle signs often become clearer in later toddler years.
  • Proper diagnosis requires trained experts performing developmental assessment and a medical evaluation.

Instructions / methodology mentioned

How ASD should be diagnosed (high-level process)

  • One or more experts should:
    • Gather a thorough developmental history
    • Directly assess the child’s developmental abilities
    • Conduct a medical exam
