Insights

The Ages and Stages Questionnaire (ASQ) effectively identified cognitive deficits in extremely preterm infants. This validated tool measured an average developmental deficit of -1.06 SD in these children compared to term-born peers.

Area of Science:

  • Developmental Pediatrics
  • Neonatal Neurodevelopment
  • Screening Tools in Pediatrics

Background:

  • Extremely preterm birth is associated with an increased risk of neurodevelopmental impairments.
  • Early identification of cognitive deficits is crucial for timely intervention.
  • The Ages and Stages Questionnaire (ASQ) is a parent-completed screening tool for child development.

Purpose of the Study:

  • To validate the Ages and Stages Questionnaire (ASQ) for use in extremely preterm infants.
  • To quantify the average cognitive deficit in children born extremely preterm using the ASQ.

Main Methods:

  • A cohort of term children (n=30) aged 36-42 months completed the ASQ, and underwent cognitive assessment using the Wechsler Preschool and Primary Scales of Intelligence--Revised.
  • A second study involved obtaining ASQ data from extremely preterm infants (n=22) and term-born controls (n=19) aged 35-44 months.

Main Results:

  • A significant correlation was found between overall ASQ scores and IQ scores (p=0.007).
  • Children born extremely preterm demonstrated an average ASQ score of -1.06 Standard Deviations below that of term-born children (p=0.048).

Conclusions:

  • The ASQ is a validated tool capable of identifying developmental deficits in extremely preterm infants.
  • The ASQ accurately measured a cognitive deficit of the expected magnitude in this high-risk population.

Binet's Contribution to Measures of Intelligence

Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing designs from...

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

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.

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...
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...
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...
