life span Flashcards
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
what is objective permanence
the child understands that people and objects exist even when they can’t see them
what is goal directed behaviour
children realise specific actions have a result
what is the pre-operational stage
- piaget
- 2-7 years
-Children begin to think symbolically (objects can represent ideas)
-Begin to see imaginative play eg. pretending to be a teacher. Nurse, doctor etc.
-Child begins to think in more complex ways
what are key features of pre-operational stage
Egocentrism
Animism
Transformation
Centration
Reversibility
what is egocentrism
-Is a concept what children at this stage do not understand
-The child is only able of thinking about things on their own point of view
what is animism
-Is the belief that everything is alive and has feelings
-This is generally linked with egocentrism, and these children believes that everything feels exactly the same as themselves
what is transformation
-Is the understanding that things can change shape or form
-A child can understand that ice melts and turners into water but cannot explain why this occurs
what is centration
-A child can only focus on one quality at a time, at this stage do not understand
-Eg the child can only focus on the length of a group of objects, they cannot take into account the quantity and space
what is reversibility
-The ability to track an argument to its starting point
-This accomplishment develops in the later years of the preoperational stage
what is the formal operational stage
-12+ years
-Children can think abstractly and reason about hypothetical problems
-More complex thought processes become evident and thinking becomes more sophisticated
-Individuals can think about moral, philosophical, ethical, political, issues, etc.
what are the key accomplishments in the formal operational stage
-Abstract thinking: a way of knowing what something is would literally seeing it “what is honesty”
-Logical thinking: individuals can develop plans to solve problems. Identify a range of possible solutions. Develop hypotheses and systematically test solution
