Child and Adolescent Growth and Development

Vocabulary practice flashcards covering developmental milestones, psychosocial stages, cognitive theories, physical parameters, and pediatric health risks from toddlerhood through adolescence.

Toddlerhood

The developmental stage occurring between $1$ and $3\,\text{years}$ of age, characterized by a slow and steady growth rate, advancing gross and fine motor skills, rapid language acquisition, and the pursuit of independence and autonomy.

Greenstick Fracture

A partial bone break common in children aged $2\text{--}3\,\text{years}$ where a bone bends and cracks along one side without breaking completely into multiple pieces, owing to the high flexibility of young bones.

Anterior Fontanel

The diamond-shaped, membrane-covered space located at the junction of the frontal and parietal bones of an infant's skull that normally closes completely by $18\,\text{months}$ of age.

Ossification

The physiological process of bone development and hardening that is initiated during childhood and reaches completion during puberty or the adolescent stage of development.

Autonomy vs. Shame and Doubt

Erikson's second psychosocial stage occurring from $1$ to $3\,\text{years}$ of age, centered around the question 'Can I do things myself or am I reliant on the help of others?', with the basic virtue of Will and the milestone of toilet training.

Regression

A behavioral phenomenon in which a child returns to an earlier developmental stage (such as a $2\text{-year-old}$ requesting a bottle or having angry outbursts) when coping with stress, illness, or changes such as the birth of a newborn sibling.

Separation Anxiety

An emotional distress response exhibited by young children when separated from primary caregivers, characterized by two primary phases: Protest (loud crying, kicking, and attempting to run toward the door) and Despair (withdrawn, quiet behavior, sadness, and thumb sucking).

Amblyopia

A visual disorder (commonly called lazy eye) causing blurry vision where the brain progressively ignores visual input from the weaker eye and relies on the stronger eye; untreated cases can impair depth perception and coordination and may be complicated by strabismus.

Binocular Vision

The physiological capacity of both eyes to focus and work together synchronously to produce a single, unified, three-dimensional perception of the environment.

Object Permanence

A Piagetian cognitive milestone acquired during toddlerhood whereby the child understands that objects and people continue to exist even when they are out of sight.

Preoperational Thought

Piaget's second cognitive developmental stage characteristic of toddlers and preschoolers, characterized by symbolic function, egocentrism, limited problem-solving ability, developing memory, and an inability to perceive danger.

Parallel Play

A form of play typical of children aged $2+\,\text{years}$ where the child plays alongside or near other children using similar toys without directly interacting or cooperating with them.

Symbolic Play

A form of play in which a child uses objects to represent other things or mimic adult roles, such as a $2\text{-year-old}$ toddler building a castle out of wooden blocks.

Solitary Play

A stage of play occurring between $0$ and $2\,\text{years}$ of age where a child plays entirely alone and demonstrates no interest in engaging with others.

Initiative vs. Guilt

Erikson's third psychosocial stage occurring in preschool children ($3$ to $5\,\text{years}$ or $3$ to $6\,\text{years}$), centered on the question 'Am I good or bad?', yielding the basic virtue of Purpose through active role exploration and play.

Centration

A preoperational cognitive limitation identified by Piaget in which a preschool child focuses entirely on a single prominent perceptual cue or aspect of a situation while neglecting all others.

Lack of Reversibility

A cognitive limitation in the preoperational stage where a child cannot mentally conceptualize that an action, alteration, or transformation can be undone or returned to its original state (such as understanding that a flat beach ball can be reinflated).

Magical Thinking

A normal cognitive characteristic of preschool-age children in which they believe their personal thoughts, desires, or behaviors possess direct causal influence over real-world external events (such as believing parental divorce is their fault).

Preconventional Morality

Kohlberg's level of moral development spanning ages $4$ to $10\,\text{years}$, where moral decisions and behaviors are guided primarily by the desire to receive rewards or avoid punishment.

Industry vs. Inferiority

Erikson's fourth psychosocial stage occurring in school-age children ($6$ to $11\,\text{years}$), where children perceive themselves as producers and gain self-worth from mastery and accomplishment fostered by positive reinforcement.

Concrete Operational Stage

Piaget's third cognitive stage beginning in school-age children ($6$ to $11\,\text{years}$), marked by a transition from egocentric thinking to organized, logical thought, understanding of causation, conservation, and systematic categorization.

Seriation

A concrete operational cognitive ability developed during the school-age period that enables a child to order and sort items systematically based on specific measurable properties or dimensions.

Reciprocity

A moral concept emerging during the school-age transition toward conventional morality characterized by mutual give-and-take, willingness to share, and actively caring for the needs of others.

Latency Stage

Freud's psychosexual stage corresponding to the school-age period ($6$ to $11\,\text{years}$) during which sexual drives and feelings remain dormant and unexpressed while energy is directed toward social and educational pursuits.

Scoliosis

An abnormal lateral curvature deformity of the spine that presents as a clinical risk in school-age children as their bodily center of gravity shifts downward.

Cooperative Play

An organized form of play emerging around $4+\,\text{years}$ and dominant in school age where children play together toward a shared objective, take turns, abide by established rules, and engage in team activities.

Identity vs. Role Confusion

Erikson's fifth psychosocial stage occurring during adolescence ($12$ to $18\,\text{years}$ or $12$ to $20\,\text{years}$), focused on resolving the question 'Who am I?' through establishing personal values, career goals, and peer group affiliation.

Formal Operational Stage

Piaget's final cognitive stage emerging during adolescence, characterized by the capacity for logical, scientific reasoning and abstract thinking, including anticipating future possibilities based on prior experiences.

Ambivalence

An emotional state commonly experienced during adolescence characterized by simultaneously holding two opposing feelings or attitudes (such as love and hate) toward the same person or situation.

Bulimia

An eating disorder prevalent in adolescence characterized by discrete episodes of binge eating followed by compensatory purging behaviors.

Anorexia

A serious adolescent eating disorder characterized by chronic self-starvation, severe restriction of caloric intake, and significant weight loss.

Human Papillomavirus (HPV) Vaccine

A primary prevention immunization recommended for administration to children aged $9\text{--}12\,\text{years}$ to prevent infection by HPV and the development of cervical cancer.
