Insights

Very preterm infants show delayed oculomotor response shifting, impacting later executive function. Early attention and cognitive development are linked to this infant behavior, highlighting risks for preterm children.

Area of Science:

  • Developmental neuroscience
  • Pediatric neurology
  • Cognitive psychology

Background:

  • Preterm children face higher risks for executive functioning deficits, impacting behavior and attention.
  • Early cognitive flexibility may predict later executive function, but its development and relation to neurobehavioral outcomes in preterm infants are unclear.

Purpose of the Study:

  • To investigate oculomotor response shifting in preterm and term infants at 12 months.
  • To examine the relationship between early oculomotor response shifting and later cognitive development and effortful control at 18 months.

Main Methods:

  • Longitudinal study involving 27 preterm and 25 term infants.
  • Oculomotor response shifting assessed at 12 months.
  • General cognitive development and effortful control assessed at 18 months.

Main Results:

  • Very preterm infants showed impaired inhibition of perseverative looking at 12 months compared to moderate-to-late preterm and term infants.
  • Lower inhibition of perseverative looking correlated with poorer general cognitive development and attentional shifting at 18 months.

Conclusions:

  • Atypical oculomotor response shifting in infancy may serve as an early behavioral marker for neurodevelopmental risks in preterm children.
  • These findings suggest potential for early identification of attention-related problems in preterm populations.

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...

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...

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.

Piaget's Stage 1 of Cognitive Development01:14

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.

Neuroplasticity01:01

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...
