Autism and Social Communication Disorder on the Praxis 5331

Social communication is one of the Big Nine and a reliable source of Praxis 5331 items — usually framed as a case: a child with adequate vocabulary and grammar who can't sustain a conversation, or a differential between autism spectrum disorder (ASD) and social (pragmatic) communication disorder (SCD).

The differential that decides most items

• ASD requires both persistent social communication deficits and restricted, repetitive behaviors, interests, or activities (RRBs), including sensory differences.
• Social (pragmatic) communication disorder has the social communication deficits without RRBs — and it cannot be diagnosed if ASD criteria are met.
• Developmental language disorder affects form and content (syntax, morphology, vocabulary) more than social use.
• ADHD can look pragmatically impaired through impulsivity and turn-taking violations, but social understanding is intact.

What "social communication" contains

Four interacting components the exam expects you to name:

• Social interaction — greetings, turn-taking, joint attention
• Social cognition — theory of mind, inference, perspective-taking
• Pragmatics — speech acts, register, presupposition, topic maintenance and repair
• Language processing — comprehension of figurative and non-literal language

Early red flags

• Limited or absent joint attention by 12 months — the single strongest early marker
• No pointing to share interest (protodeclarative) by 14 months
• No response to name by 12 months
• Absence of pretend play by 18 months
• Loss of previously acquired speech or social skills at any age

Compare with the typical sequence in the milestones guide.

Assessment

Standardized language tests routinely miss pragmatic breakdown. Expect the correct answer to combine methods:

• Naturalistic observation across partners and settings
• Caregiver and teacher interviews / rating scales (CCC-2, SRS-2, Social Language Development Test)
• Language sample analyzed for discourse and repair
• ADOS-2 and ADI-R — diagnostic instruments used by a team; SLPs contribute but ASD diagnosis is interdisciplinary
• Dynamic assessment to gauge learning potential and reduce cultural bias

Pragmatic norms are culturally bound. Eye contact, interruption, and directness vary widely by community — see cultural responsiveness before labeling a difference a disorder.

Evidence-based intervention

• Naturalistic developmental behavioral interventions (e.g., JASPER, ESDM) — play-based, follow the child's lead, embed targets in routines.
• Video modeling and peer-mediated instruction — strong evidence for generalization.
• Social narratives and comic strip conversations for predictable routines and perspective-taking.
• Visual supports — schedules, choice boards, first/then.
• AAC for minimally speaking clients; robust evidence shows it supports rather than suppresses speech. See the AAC guide.
• Environmental arrangement and communication temptations to create genuine reasons to communicate.

The exam favors naturalistic, generalizable, client- and family-centered answers over decontextualized drill or compliance training. Answers that frame the goal as "appearing neurotypical" are wrong; goals should increase communicative effectiveness and participation.

Working with the team

School-based services flow through the IEP; social communication goals must connect to educational access — see IEP basics. Early intervention for under-3s runs through IFSPs with family coaching, covered in early intervention.
