Warm-up Activity (5 minutes)

Activity: Brainstorming Session

• 🗣️ Ask students to share what they already know about Autism Spectrum Disorder.

• 💡 Briefly address any misconceptions about ASD.

Main Instruction

Part A: Understanding the Core Deficits

I. Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history:

• 🤝 Deficits in social-emotional reciprocity:
  • 🗣️ Abnormal social approach

  • 👁️ Reduced sharing of interests, emotions, or affect
  • ⛔ Lack of initiation of social interaction
• 🎭 Deficits in nonverbal communicative behaviors used for social interaction:
  • 👁️ Poorly integrated verbal and nonverbal communication
  • 👁️ Abnormalities in eye contact and body language
  • 😥 Deficits in understanding and use of gestures
  • 表情 Total lack of facial expression and nonverbal communication

  • 🤝 Difficulties adjusting behavior to suit various social contexts
  • 👯 Difficulties in sharing imaginative play or in making friends
  • 🧑‍🤝‍🧑 Absence of interest in peers

II. Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history:

• 🗣️ Stereotyped or repetitive motor movements, use of objects, or speech:
  • 🤸 Simple motor stereotypes
  • 玩具 Lining up toys or flipping objects
  • 🗣️ Echolalia
  • 🗣️ Idiosyncratic phrases
• 🧩 Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior:

  • трудности Difficulties with transitions
  • 儀式 Rigid thinking patterns

  • ✨ Excessive smelling or touching of objects
  • 💡 Visual fascination with lights or movement

Severity is based on social communication impairments and restricted repetitive patterns of behavior.

📝 Assessment

Case Study Analysis:

Present students with several case studies illustrating individuals with varying presentations of ASD. Have them identify which diagnostic criteria are met in each case and determine the level of severity.
