Insights

Children born very preterm (VPT) or with very low birth weight (VLBW) showed cognitive deficits in shifting but not inhibition or working memory. Behavioral measures indicated everyday working memory challenges, highlighting the need for combined assessments.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatrics

Background:

  • Children born very preterm (VPT) and/or very low birth weight (VLBW) may experience executive function (EF) challenges.
  • Executive functions encompass inhibition, working memory, and shifting, crucial for daily functioning.
  • Understanding sex differences in EF for VPT/VLBW children is important.

Purpose of the Study:

  • To compare cognitive and behavioral executive functions in VPT/VLBW children versus term-born controls.
  • To investigate potential sex differences in executive function performance.
  • To determine the congruence between cognitive and behavioral EF measures.

Main Methods:

  • Fifty-two VPT/VLBW children and 36 term-born controls (aged 8-12 years) participated.
  • Cognitive EF was assessed using inhibition, working memory, and shifting tasks.
  • Behavioral EF was evaluated through maternal reports on the Behavior Rating Inventory of Executive Function (BRIEF).

Main Results:

  • VPT/VLBW children performed significantly lower on cognitive shifting tasks compared to controls.
  • Mothers reported more behavioral working memory problems in VPT/VLBW children.
  • No significant sex differences were found in cognitive or behavioral EF measures.

Conclusions:

  • Cognitive and behavioral assessments of executive functions are not always congruent in VPT/VLBW children.
  • VPT/VLBW children may exhibit specific difficulties in cognitive shifting and everyday working memory.
  • Combined cognitive and behavioral instruments are essential for comprehensive identification of executive difficulties in clinical practice.

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 also...
Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
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 exist...
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 Development during Infancy01:30

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 2 of Cognitive Development01:14

Piaget's Stage 2 of Cognitive Development

The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...
