Insights

Three distinct sensory profiles were identified in preschool children with neurodevelopmental disorders (NDDs). These sensory profiles significantly correlate with emotional and behavioral regulation, independent of diagnosis, highlighting the importance of sensory assessments for early intervention.

Area of Science:

  • Neurodevelopmental Disorders
  • Sensory Processing
  • Child Psychology

Background:

  • Atypical sensory processing is a key feature across neurodevelopmental disorders (NDDs).
  • Sensory processing difficulties significantly impact emotional and behavioral regulation in children.
  • Understanding distinct sensory profiles is crucial for targeted interventions.

Purpose of the Study:

  • To identify distinct sensory processing profiles in preschool children with NDDs.
  • To investigate the association between sensory profiles and emotional-behavioral functioning.
  • To examine the link between sensory profiles and cognitive/developmental status.

Main Methods:

  • Latent profile analysis (LPA) was used to identify sensory subtypes in 263 children (aged 21-71 months) with NDDs.
  • Sensory processing, emotional-behavioral functioning, and cognitive/developmental levels were assessed using standardized instruments.
  • Multinomial logistic regression analyzed profile characteristics and predictors of profile membership.

Main Results:

  • Three sensory profiles emerged: Multisystemic Sensory Dysfunction (20.1%), Typical Sensory Processing (44.9%), and Mixed Subclinical Sensory Processing (35%).
  • The Multisystemic profile, prevalent in autism spectrum disorder (ASD), showed pervasive sensory and emotional difficulties.
  • Typical sensory processing was most common in language disorder (LD), while the Mixed profile spanned all diagnoses.
  • Higher cognitive functioning and fewer internalizing symptoms predicted typical sensory processing.
  • A clear gradient of symptom severity was observed across profiles, with the Multisystemic group exhibiting the most significant emotional-behavioral impairments.

Conclusions:

  • Distinct sensory-emotional phenotypes exist across NDD diagnostic categories, supporting a dimensional model of neurodevelopment.
  • Sensory profiles are strongly linked to emotional functioning, irrespective of specific diagnosis.
  • Early sensory assessment can provide valuable insights into emotional vulnerability and guide interventions for preschool children with NDDs.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Socioemotional Experience and Gender Development01:30

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
