Ch. 4 Development Flashcards
Brain Development
The brain develops connections that branch out as you grow
- Pruning
- Frontal Lobe rapid growth age 3-6
- Limbic System is evolutionary oldest, association areas last to develop
Pruning
Stimulation is required as an infant, or pruning occurs (connections fade away if baby doesn’t use them; use it or lose it)
Consequences of brain development for behavior
association areas are last to develop, so decision making and thinking is not present in younger brains
How memory changes over development
recognition memory does not decrease, but recall does; meaningless information more difficult to remember
Infantile Amnesia
inability to remember; avg earliest memory is 3.5 years
Stages of Cognitive Development (Piaget)
- Sensorimotor
- Preoperational
- Concrete Operational
- Formal Operational
Sensorimotor Stage
Birth- ~2yrs
- Object Permanence (6-8 months): awareness that things continue to exist even when they are not perceived
- Scale Errors: mistaking a small, play object for the real thing
- Mouthing: use senses to investigate the world
Preoperational Stage
~2yrs- ~6/7yrs
- Egocentric: have difficulty taking another’s point of view
- Lack conservation because they can only focus on one dimension
- Thinking with words and images
- Pretend play: imaginative play with symbolic objects (is still abstract?)
Concrete Operational Stage
~7yrs- ~11yrs
- Pass the egocentrism task (can take another’s point of view)
- Pass the Conservation Task: understanding that properties (mass, vol., #) remain the same despite changes in form
- Theory of Mind: understanding that others’ mental states (feelings, perceptions, thoughts) may be different from yours
- Mathematical transformations: easily reversing mathematical operations
- Conservation & mathematical transformations both on being able to “reverse” thinking
Formal Operational Stage
~12 yrs onward
Abstract thought
Logic & hypothetical reasoning
Ethical and moral reasoning
Kohlberg’s Moral Reasoning Theory
Preconventional Morality
Conventional Morality
Postconventional Morality
Preconventional Morality
Self interest, judgements are based on fear of punishment or hope of concrete rewards
Conventional Morality
judgements are based on social rules, laws, & norms; less self-interested (but only because of law/ rule)
Postconventional Morality
judgements are based on individual rights and social circumstances or follow personally perceived ethical principles
Attachment
Strong emotional tie between caregiver and child
Based on contact, familiarity, and trust
Function on both parents and children (ex: difficult vs. easy temperament)
Foundation of adult relationships
