Insights

Externalizing behaviors are present in 12-month-olds and can be reliably assessed. These behaviors, while less frequent than in older toddlers, show stability and context correlations, warranting further research.

Area of Science:

  • Child Psychology
  • Developmental Psychology
  • Behavioral Science

Background:

  • Investigates externalizing behaviors in infants and toddlers.
  • Compares 12-month-olds to 24- and 36-month-olds.
  • Examines behavior occurrence, informant agreement, stability, and context.

Purpose of the Study:

  • To assess externalizing behaviors in 12-month-old children.
  • To compare these behaviors across different early childhood age groups.
  • To validate the Child Behavior Checklist (CBCL) for infant assessment.

Main Methods:

  • Utilized the Child Behavior Checklist (CBCL/1½-5) with mothers and fathers.
  • Collected data from a large general population sample (N=786 to 744).
  • Assessed 1-year stability and child, mother, and family characteristics.

Main Results:

  • Externalizing behaviors occurred frequently in 12-month-olds, though less than in older children.
  • Mother-father agreement and 1-year stability were significant but lower in 12-month-olds.
  • Context characteristics correlated with behaviors similarly across age groups.

Conclusions:

  • Externalizing behaviors in 12-month-olds are a valid area for research.
  • The CBCL can be used to validly assess these behaviors in infants.
  • Findings support early identification and intervention for behavioral concerns.

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

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.

Attachment01:20

Attachment

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...
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.

Psychosexual Stages of Personality: Anal01:26

Psychosexual Stages of Personality: Anal

Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...
