Ecological systems theory

holds that people encounter different environments throughout their lifespan that may influence behavior in varying degrees

Microsystem

an individual's immediate environment which includes the people the person interacts with daily, having the most direct, immediate impact on the individual

Mesosystem

a connection of two or more microsystems, such as a child's home and school

Exosystem

environments in which an individual is not an active participant, yet these still impact the person's development (e.g., mass media or government policies)

Macrosystem

the idea that development takes place in unique stages, which happen at specific times or ages (e.g., Erikson's 8 stages of development)

Lifespan development

the study of patterns of growth, change, and stability in behavior that occur throughout the entire life span

Stability and change

stability refers to traits and behaviors that remain more or less constant throughout a person's life, while change refers to traits and behaviors that are more fluid and flexible

when children use grammar in an irregular way as they are learning the rules (e.g., "I runned", "he hitted", "you buyed")

Behavioral perspective

a theory suggesting that behavior is learned and is shaped by observable, environmental factors

Classical conditioning

a learning process that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behavior (e.g., salivation)

Association

when a subject is conditioned to connect a stimuli with another stimuli, and this results in a specific behavior
