Information Processing Approach01:30

Information Processing Approach

80
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...

Piaget's Stage 1 of Cognitive Development

676
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

122
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...

The Nativist Approach01:21

The Nativist Approach

89
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...

Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

85
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...

Piaget's Theory of Cognitive Development from Childhood into Adulthood

172
Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.

Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Public Health

Background:

  • Digital media exposure in children is a growing concern.
  • Early screen time is associated with extensive negative effects.
  • Understanding these impacts is crucial for child development.

Purpose of the Study:

  • To evaluate the association between screen time at 18 months and cognitive development.
  • To assess cognitive development in a Southern Brazil population-based sample.

Main Methods:

  • Cross-sectional study using data from a population-based cohort.
  • Sample included 470 children with completed cognitive assessments.
  • Cognitive development measured by Bayley Scales of Infant Development - Third Edition (BSID-III).
  • Screen time assessed via caregiver questionnaire.

Main Results:

  • 58.8% of children had ≥1 hour of screen time daily.
  • Lower cognitive development observed in children with mothers of lower education.
  • Boys showed different cognitive development trajectories.
  • Children exposed to ≥2 hours of screen time/day had lower cognitive development.

Conclusions:

  • Screen exposure shows a significant negative association with children's cognitive development.
  • Intervention and parental guidance on digital media impact are recommended.
  • Further research is needed to confirm findings and expand knowledge on the topic.
