Exam #4 Flashcards
developmental psychology
- study of changes across the lifespan
- physical, cognitive, moral, social
- as a result of biological & environmental influences
cross-sectional design
different age groups are studied at one time
longitudinal design
group of participants is studied over time
nature
human development is governed by automatic, genetically predetermined signals
nurture
development occurs by learning through experience
examples of nature vs. nurture
- intelligence
- language
- aging
intelligence
- nature: genes/biology determines IQ
- nurture: environment & learning from early on
language
- nature: Language Acquisition Device (innate “program” that contains a schema for human language)
- nurture: operant and observational learning
aging
- nature: cellular clock theory (limits on # of times cells can reproduce)
- nurture: wear-and-tear theory (repeated use and abuse of body’s tissues)
interactionist perspective
development results from combination of genes and experiences in the environment
continuity of stages
- cognitive development/skills develop in stages (qualitative)
- physical development/motor skills continuous (quantitative)
Jean Piaget
- children are driven by an innate need to know, as part of our overall need for survival
- in order to survive, we need to adapt to out environment
- cognitive development
3 concepts of cognitive development
- schemas
- assimilation
- accommodation
schemas
files of knowledge that act like a set of blueprints for figuring out our environment
assimilation
process of taking in new info that fits into schema
ex. 5 year old thinks all cats are furry bc she has a cat
accommodation
occurs when new info cannot be assimilated and the schema must be changed
Piaget’s 4 stages
- sensorimotor
- pre-operational
- concrete operational
- formal operational
sensorimotor stage
- birth to 2
- cannot think about their environment using language, symbols, images
- object permanence > awareness that objects and people continue to exist even if they are out of sight
pre operational stage
- 2 to 7
- can represent things w/ words (language) & pictures but lack logical reasoning (operations)
- egocentrism > view of the world entirely form own perspective
- animism > belief that all things are living
- understanding of conservation > awareness that physical quantities remain constant despite changes in shape of appearance
concrete operational stage
- 7 to 12
- develop ability to think logically but not abstractly or hypothetically
- master principle of conservation & reversibility
formal operational stage
- 12 to adulthood
- adds abstract, reasoning, & conceptualization
- hypothetical thinking (What if…?)
- deductive reasoning (If… then)
- only 40-60% reach this stage
- Important bc values and beliefs, can reason from the “real” to the “possible”, & thinking about what “could be” to “should be” (right vs wrong)
Kohlberg’s Levels
-pre conventional
-conventional
-post conventional
(moral development)
(based on white men)
pre conventional level
- birth to adolescence
- self-centered
conventional level
- adolescence and young adulthood
- other-cenetered (think about other people)
