Insights

Preterm infants often show signs of sensory processing disorder (SPD), particularly sensory overresponsivity. Early education and screening for SPD in these vulnerable infants are crucial for timely intervention.

Area of Science:

  • Developmental Pediatrics
  • Neuroscience
  • Child Psychology

Background:

  • Sensory Processing Disorder (SPD) affects development in young children.
  • Preterm infants represent a population at higher risk for developmental challenges.
  • Understanding SPD prevalence in preterm infants is critical for early intervention.

Purpose of the Study:

  • To systematically review and synthesize evidence on the prevalence and patterns of SPD in preterm infants (birth to 3 years).
  • To identify specific SPD subtypes and their occurrence in this population.
  • To inform healthcare providers and caregivers about SPD in preterm infants.

Main Methods:

  • Systematic review of multidisciplinary literature.
  • Inclusion of 45 articles covering physiological, behavioral, and temperament research.
  • Analysis of 295 findings related to SPD in preterm infants aged birth-3 years.

Main Results:

  • 44% of findings indicated evidence of SPD in preterm infants.
  • Sensory Modulation Disorder (SMD) was the most common category (43% positive findings).
  • Sensory overresponsivity was the most prevalent SMD subtype (82% of SMD findings positive).
  • Limited evidence was found for sensory underresponsivity, sensory-seeking SMD, sensory discrimination disorder, and sensory-based motor disorder.

Conclusions:

  • Evidence supports the need for educating neonatologists, pediatricians, and caregivers about SPD symptoms in preterm infants.
  • Findings justify follow-up screening for SPD in children born preterm.
  • Further research utilizing measures based on sensory processing theory is recommended.

Piaget's Stage 1 of Cognitive Development

The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

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.

Sensory Perception: Organization of the Somatosensory System

The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Parallel Processing01:20

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...
