Term
Psychoanalytic theories
Definition
Includes psychosexual and psychosocial. Development is an active dynamic process influenced by a person’s inborn biological drives and unconscious social and emotional experiences. Freud and Erikson.
Term
Cognitive Theories
Definition
How thinking and problem solving skills develop over time, Piaget, information processing.
Term
Behaviorism/learning
Definition
studies observable behaviors, recognized learning experiences over time as source of developmental changes. Describes learning as relatively permanent change in the capacity to perform certain behaviors that result from experience.
i. Learning theory: emphasized the sequences and processes of conditioning that underlie most human and animal behavior.
1. Conditioning: relationship between stimulus and response.
2. Classical conditioning: Ring a bell, dog salivates. (Pavlov)
3. Operant conditioning: Positive and negative reinforcement. (Skinner)

Theory
Definition

Term
Piaget
Definition
i. The way people think and understand shapes their behavior and personality.
1. Scheme: internal cognitive structure that provides procedure to use in a specific circumstance.
2. Assimilation: process of using those schemes to make sense out of experiences.
3. Accommodation: changing a scheme as result of new information.
4. Equilibration: balancing assimilation and accommodation to create new schemes.
ii. Four major stages:
1. Sensory motor (0-18 mos): using senses and motor skills.
2. Pre operational (18 mos-6 yrs): learning about symbols, points of view.
3. Concrete operational (6-12): begin to learn logic based on concrete examples they can see.
4. Formal operational (12+): manipulate ideas and ask “what if?”
Term
Vygotsky
Definition
i. Thinking doesn’t occur in a vacuum
ii. Understanding one’s culture-so that knowledge and skills are relevant
iii. Development is an apprenticeship- one works with a skilled teacher to develop (parents, teachers, siblings, peers)
1. Guided participation: direct working with someone else to guide them through the process. Ex. Making bread.
2. Zone of proximal development: what someone can do with some assistance. Ex. Riding a bike.
3. Scaffolding: activities that we do to help someone else learn. Ex: hold baby’s hand to help walk.
