Symptoms Of Social Communication Disorder In Kids

Quick Summary

Communication disorders in children range from speech sound errors to difficulty understanding language to challenges using language socially. Social communication disorder (SCD) is a specific condition characterized by persistent difficulties using language appropriately in social contexts, including conversation, nonverbal communication, and understanding implied meaning. SCD differs from autism in that it does not include restricted interests or repetitive behaviors. Early identification and speech-language therapy significantly improve outcomes.

Communication is more than words. It is the timing of when you speak, the tone you choose, the way you read a room, the ability to know when a joke is welcome and when it is not, and understanding that "can you pass the salt?" is a request rather than a yes-or-no question. These are communication skills so automatic for most people that they barely notice using them.

Recognizing communication disorder symptoms is an important first step toward getting the right support. For children with communication disorders, particularly social communication disorder, these implicit rules of language are genuinely difficult. They are not choosing to be rude, odd, or socially awkward. They are navigating a complex social world without the intuitive map that most people develop naturally.

Understanding what communication disorders are, how social communication disorder specifically presents, and the communication disorder symptoms to watch for helps families and educators respond with knowledge rather than frustration.

At Innovative Interventions, our speech-language pathologists work with children across New Jersey to address the full spectrum of communication challenges, including social communication, as part of our early intervention and pediatric speech therapy services.

What Are Communication Disorders?

Communication disorders are conditions that affect a person's ability to communicate, whether through speech, language, or the social use of language. The American Speech-Language-Hearing Association (ASHA) defines communication disorders as impairments in the ability to receive, send, process, and comprehend verbal, nonverbal, and graphic symbol systems.

Communication disorders vary widely in type, severity, and cause. They can affect a single narrow area of communication, such as the production of one specific speech sound, or they can affect broad, fundamental aspects of how a person understands and uses language to connect with others. For an overview of the full range of speech sound disorders, see our post on speech sound disorders in children.

Main Types of Communication Disorders in Children

Speech Disorders

Speech disorders affect how sounds are produced. They include articulation disorders (difficulty producing specific sounds), phonological disorders (systematic sound pattern errors), childhood apraxia of speech (motor planning difficulties affecting speech), dysarthria (muscle weakness or coordination affecting speech), and fluency disorders such as stuttering.

Language Disorders

Language disorders affect the ability to understand language (receptive language disorder) or to express oneself through language (expressive language disorder), or both. A child with a language disorder may have limited vocabulary, struggle to follow directions, have difficulty forming sentences, or be unable to retell a story in a logical sequence.

Social Communication Disorder (SCD)

Social communication disorder is a distinct diagnostic category introduced in the DSM-5 in 2013. It describes a condition in which a child has significant, persistent difficulties using communication for social purposes, even when their language structure (vocabulary and grammar) is otherwise adequate.

SCD is different from autism spectrum disorder in one important way: children with SCD do not have the restricted interests and repetitive behaviors that are part of the autism diagnostic criteria. SCD is a social communication difficulty without those additional features. Distinguishing between SCD and autism is a clinical judgment that requires comprehensive evaluation by an experienced multidisciplinary team.

Communication Disorder Symptoms

1. Difficulty Using Language in Social Situations

Children with SCD struggle to adjust their language to fit different social contexts. They may use the same register regardless of who they are speaking to, talking to a teacher the same way they talk to a close friend, or using very formal language during casual peer play. They may not recognize that the same words carry different social weight in different settings.

2. Problems with Conversation Skills

Conversation requires a continuous series of pragmatic judgments: when to speak, how long to speak, how to signal you are listening, how to take turns smoothly, how to introduce or change a topic appropriately. Children with SCD may monopolize conversations, interrupt without awareness, fail to maintain a topic, or make abrupt topic changes that leave the other person disoriented.

3. Difficulty Understanding Nonverbal Communication

Facial expressions, eye contact, gesture, body posture, and proximity all carry communicative meaning. Children with SCD may not read these signals accurately. They may miss that a classmate is signaling boredom, that a teacher is displeased, or that a friend is hurt. They may also fail to use appropriate nonverbal communication themselves, resulting in social interactions that others experience as flat, confusing, or off-putting without being able to say exactly why.

4. Difficulty Understanding Nonliteral Language

Human language is rich with idioms, metaphors, sarcasm, humor, and implied meaning. "Break a leg," "it's raining cats and dogs," "do you have the time?" (a request, not an inquiry about your ability to tell time) are all examples of nonliteral language that most people process automatically. Children with SCD often interpret these literally, creating confusion and social difficulty.

5. Challenges with Storytelling and Narrative Skills

Effective storytelling requires organizing information in a way that accounts for what the listener knows, maintaining a coherent sequence, and including the right level of detail. Children with SCD may produce narratives that lack sufficient context for the listener, jump between events without clear logical connection, or include disproportionate levels of detail about some elements while skipping over others.

6. Social Relationship Difficulties

Because so much of human relationship is built through communication, children with SCD often struggle to form and maintain friendships. Peers may find them hard to connect with, even if they cannot articulate exactly what feels off. The child themselves may desperately want friends but not understand what is preventing those connections from forming.

This aspect of SCD can be emotionally painful and is an important reason why early identification and targeted support matter so much. A child who is helped to develop social communication skills during the preschool and early school years has a different social trajectory than one who reaches adolescence still lacking those tools.

Early Signs of Communication Disorders in Children

• Limited pointing or joint attention by 12 months

• No words by 16 months or no two-word combinations by 24 months

• Difficulty understanding simple directions beyond what is expected for age

• Speech that is significantly difficult to understand by familiar listeners

• Regression of previously acquired language or social skills at any age

Communication Disorder Symptoms by Age

Social communication difficulties present differently depending on the child's age and what is expected of them socially:

• Toddlers (1-3): Limited joint attention; reduced interest in back-and-forth vocal play; less frequent pointing and gesture compared to peers

• Preschoolers (3-5): Difficulty in group play; trouble adjusting communication for different play partners; literal interpretation of peer language

• School-age children: Struggling to understand classroom humor or implied rules; conflict with peers arising from misread social cues; difficulty with collaborative group work

• Teens: Social isolation; misreading romantic or social signals; difficulty in group conversations that require reading subtle cues

What Causes Communication Disorders?

Communication disorders arise from a range of underlying factors:

• Neurological differences: Conditions affecting brain development and function, including autism spectrum disorder, traumatic brain injury, and genetic conditions, frequently include communication difficulties

• Hearing impairment: Children who cannot hear clearly cannot learn language the way hearing children do. Undetected hearing loss is a significant cause of language and communication delay

• Developmental differences: Many communication disorders arise during the normal developmental process without a clear underlying medical cause

• Environmental factors: Limited language-rich interaction, trauma, or significantly restricted social exposure can contribute to communication difficulties

• Genetic factors: Family history of speech, language, or communication disorders is a known risk factor

When to Seek Help

Seek a speech-language evaluation if your child:

• Has difficulty being understood by people outside the immediate family

• Struggles to make or keep friends despite wanting social connection

• Consistently misinterprets what others say or is often misunderstood

• Has significant difficulty with conversation management, topic maintenance, or turn-taking

• Interprets language very literally and misses humor or sarcasm at an age when peers navigate these without difficulty

For children under three in New Jersey, early intervention services provide free evaluation and therapy in the home. Do not wait for a formal diagnosis before seeking evaluation.

Diagnosis of Communication Disorders

Communication disorders are diagnosed through comprehensive evaluation by a speech-language pathologist. For SCD specifically, evaluation must rule out autism spectrum disorder, which requires input from a developmental pediatrician, psychologist, or neurologist with autism assessment training.

A thorough evaluation includes standardized assessments, observation in naturalistic settings, parent and teacher interviews, and review of the child's developmental history.

Treatment Options for Communication Disorder Symptoms

Speech-Language Therapy

The primary treatment for most communication disorders is speech-language therapy delivered by a licensed SLP. For SCD, therapy focuses specifically on the social rules of language: conversation skills, nonverbal communication, narrative organization, perspective-taking, and flexibility across different social contexts. Treatment is typically play-based for young children and may incorporate role-play, video modeling, and explicit social scripts for older children.

Social Skills Training

For children with SCD, small-group social skills training can provide a structured environment in which to practice conversation, turn-taking, reading social cues, and conflict resolution with peers. Groups work because they provide real social interaction with support, as opposed to the simulated social interaction of individual therapy.

School-Based Support

Children with diagnosed communication disorders are typically eligible for speech and language services through their school district as part of an IEP or Section 504 plan. School-based support may include pull-out speech therapy, in-class support, and accommodations that account for the child's communication needs during instruction and assessment.

Parent Involvement Strategies

As with all communication interventions for young children, parent involvement dramatically amplifies the impact of professional therapy. Caregivers learn strategies to support social communication during daily routines, play, and family interaction. Our speech therapy team coaches families in these strategies as a core part of every session.

Supporting a Child with Communication Challenges

Beyond professional intervention, families can support children with communication disorders by:

• Creating predictable, low-pressure communication opportunities at home

• Reading books with socially complex characters and discussing emotions, motivations, and perspectives

• Narrating social situations: "I think he is upset because... what do you think?"

• Role-playing common social scenarios so the child has practiced scripts to draw on

• Advocating at school for appropriate support and accommodations

Key Takeaways

• Communication disorders include speech disorders, language disorders, and social communication disorder (SCD)

• SCD specifically affects the social use of language and is distinct from autism spectrum disorder

• Key symptoms include difficulty with conversation, nonverbal communication, nonliteral language, and social relationships

• Early identification and speech-language therapy significantly improve outcomes

• Parent involvement is a critical component of effective communication intervention

• Children under three in New Jersey can access free evaluation and therapy through the early intervention program
