life span Flashcards
(88 cards)
what is life span
-it is development psychology
-stages of people from conception to death
what are the different periods of developments
- infancy →birth -2 years
- early childhood→2-5 years
- adolescence→12-18 years
- early adulthood→18-40 years.
- Middle adulthood→40-60 years
- late adulthood→60+ years
what are the areas of development
- physical- changes in the body
- cognitive- change in mental ability Eg, memory, language skills, decision making.
- social- changes in relationships, the ability to react with others
- emotional- changes in your feelings and how you express them
what is quantitative changes
a change in the amount of thought feeling or behavior
what is Qualitative changes
change in quality, kind of type Eg: crawling to walking
what are the two different views of development
continuous and discontinuous
what is continuous development
- development is gradual and ongoing
- quantitative changes are continuous
-consider height- we gorw in very, very small amounts each day
what is discontinuous development
- development has distinct and separate stages that you progress
-qualitative changed are discontinuous
Advantages of cross-sectional research
- results can be collected quickly (ask each group at the same time)
- less likely that participants will withdraw from the research
cheap
Disadvantages to cross-sectional research
-it does not determine cause and effect
-cohort effects- people in the same age group may have been affected by a shared experience
what is Longitudinal research
-Research is repeated with the same people many times
-For example: at school we may investigate if students mathematics skills improve as they get older
-We could test this every two years (NAPLAN)
Advantages of Longitudinal research
It is possible to identify patterns over time
Observation of changes is more accurate than cross-sectional studies
disadvantages of Longitudinal research
Time consuming
Expensive
Participant drop out
what are the differences between cross sectional and longitudinal
cross section longitudinal
-1 point in time. -several paints in time
-different samples -same samples
-snapshot of given - change at the individual level
point in time Eg; british birth cohort studies
Eg: british social
atitudes survey
who is piaget
- Swiss psychologist know for his work on children development
what does piaget theories of development include
-Schema theory
-Accommodation vs. assimilation
-Four stages of cognitive development
schema are used to…
-Organise our knowledge
-To assist recall
-To guide our behaviour
-To predict likely happening
-To help us to make sense of current experiences
what is a schema
- Schemas are cognitive structures that are derived from prior experience and knowledge
-They set up expectations about what is probable in relation to particular scenarios
-Schemas are culturally specific but may vary even within a single culture because of such factors as class
what are the two ways we deal with new information
Accommodation
-When as existing schema is replaced
Assimilation
-When you add information to your schema
what are the stages of cognitive development
-Sensorimotor stage- birth to 2 years
-Preoperational stage- 2-7 years
-Concrete operational stage- 7-11 years
-Formal operational stage-12 and up
what is the sensorimotor stage
- piaget
-happens between birth to 2 years - children learn about the word around them through sensation and movement
-use basic actions like grasping, looking and listening
what is the reaction that happens between 1-4 months
Primary circular reaction-Begin to repeat pleasurable actions
what is the reaction that happens between 4-8 months
Secondary circular reactions-Intentionally repeat actions to trigger a response
what is the reaction that happens between 12-18 months
Tertiary circular reactions-Trial and error experimentation
