Adolescence: Physical, Cognitive, and Psychosocial Development

Vocabulary flashcards covering biological, cognitive, and psychosocial milestones of adolescence, including puberty, Piaget's formal operational stage, reasoning types, and Erikson's and Marcia's theories of identity development.

Adolescence

The developmental period from approximately 10 to 18 years old that begins with puberty and ends with the transition to adulthood, characterized by significant cognitive development and physical growth.

Puberty

A period of rapid growth and sexual maturation that begins around age 10 for girls and age 12 for boys, contributing to gender role intensification and greater physical sex differences.

Primary Sexual Characteristics

Biological changes directly involving the reproductive organs that develop during puberty.

Spermarche

A male's first ejaculation of semen, typically occurring between 11 and 15 years of age.

Menarche

A female's first menstrual cycle, typically occurring between 9 and 14 years of age.

Secondary Sexual Characteristics

Visible physical changes signaling physical maturity that are not directly linked to reproduction, such as facial hair growth, broader shoulders, deeper voice, breast development, and broader hips.

Limbic System

A brain network that regulates emotion and reward- or novelty-seeking, which develops during adolescence and is linked to hormonal changes during puberty.

Eating Disorders

Persistent disturbances of eating or eating-related behavior that alter food consumption or absorption and significantly impair physical health or psychosocial functioning, occurring at rates 2.5 times higher in adolescent girls than boys.

Formal Operational Stage

Piaget's fourth stage of cognitive development (beginning at age 12 and continuing onward) in which individuals develop the capacity to understand abstract principles and utilize hypothetical-deductive reasoning.

Hypothetical-Deductive Reasoning

The formal operational ability to develop hypotheses based on what might logically occur, used primarily within areas of personal interest.

Transitivity

A logical property wherein a relationship between two elements carries over to other elements logically related to the first two (e.g., if $A < B$ and $B < C$, then $A < C$).

Adolescent Egocentrism

A state of heightened self-focus arising from adolescents attributing unlimited power to their own thoughts.

Imaginary Audience

The adolescent belief that those around them are as intensely concerned with and focused on their appearance and behavior as they are themselves.

Personal Fable

An aspect of adolescent egocentrism involving the belief that one is unique, special, and invulnerable to harm.

Introspection

The cognitive practice of thinking about one's own thoughts and feelings.

Idealistic (Cognitive Development)

The tendency of adolescents to insist upon high standards of behavior due to their newly acquired ability to imagine how the world could be.

Hypocrisy (Cognitive Development)

Pretending to be what one is not as a result of conforming to external social pressures and norms.

Pseudostupidity

Approaching simple problems at a level of cognitive complexity that is too high, leading to failure because the task itself is overly simple.

Inductive Reasoning

A bottom-up processing method emerging in childhood wherein specific observations are gathered to draw general conclusions.

Deductive Reasoning

A top-down processing method emerging in adolescence that begins with a general principle and proposes specific logical conclusions.

Dual-Process Model

The theory proposing that humans have two distinct, interacting cognitive networks for information processing: intuitive thinking and analytic thinking.

Intuitive Thinking

Automatic, unconscious, and fast information processing that is cognitively easier and thus relied upon more frequently.

Analytic Thinking

Deliberate, conscious, and rational information processing.

Identity vs. Role Confusion

Erik Erikson's fifth psychosocial stage (occurring during adolescence from ages 13 to 18) where the central task is to answer 'who am I?' and establish an identity.

Psychological Moratorium

A period during identity formation when adolescents put commitment on hold while actively exploring various alternative options.

Identity Diffusion

An identity status in James Marcia's model characterized by an absence of both identity exploration and ideological commitment.

Identity Foreclosure

An identity status in James Marcia's model where an individual commits to an identity without prior exploration of alternatives.

Identity Moratorium

An identity status in James Marcia's model where an individual is actively exploring alternative identities but has not yet made a commitment.

Identity Achievement

An identity status in James Marcia's model reached when an individual successfully commits to an identity following a period of active exploration.

Self-Concept

A self-description based on internal and external qualities that frequently becomes full of contradictions during adolescence.

Self-Esteem

An evaluative judgment about one's worth that often experiences a slight drop in early adolescence before recovering in mid-to-late adolescence.

Homophily

The tendency of adolescents who share similar characteristics, attitudes, and behaviors to associate and spend time with one another.

Crowd

A large, reputation-based peer group defined by shared traits or activities (such as jocks, brains, popular, or theatre) rather than personal friendships.
