Developmental Psychology Flashcards
developmental psychology
the scientific study of age related changes in behavior and mental processes throughout a person’s lifespan
Piaget’s theory of cognitive development
Piaget believed that we build an understanding of our world and develop thinking skills through active interaction with our environment
schema
an idea about what something is and how to deal with it
2 processes by which we gain and change our schemas
- assimilation: interpreting new experiences and information based on our current understanding
- accommodation: adjustments to fit particulars of new information
- we construct and modify our schemas as we interact with the world
stages of cognitive development
- sensorimotor stage: birth to 2
- pre operational stage: 2 to 7
- concrete operational stage: 7 to 11
- formal operational stage: 11 through adulthood
sensorimotor stage
- construct understanding of the world by coordinating sensory experiences with motor abilities
- live in the present and have very little understanding that things continue to exist even if they are not within sight
- foundation for cognitive abilities and growth through assimilation and accommodation
concepts of sensorimotor stage
- object permanence
- understanding that things continue to exist even after they can no longer be seen, heard or touched
- infants will be able to search for hidden objects once they understand object permanence
- infants are presented with an interesting toy and then covering it with a beret:
- infants before 6 months failed to search for the toy
- by 8 months, infant begin responding to hidden object
- goal directed behavior
- ability to behave in purposeful manner in order to achieve particular goals
- combines and coordinates existing schemas to attempt new things and achieve goals
pre operational stage
- represent the world with words, images and drawings
- stable concepts formed, mental reasoning emerges, ability to remember, pretend and imagine
- grouping similar objects together
concepts of pre operational stage
- egocentrism
- inability to take another’s POV and only perceive the world from their own viewpoint
- believe that everyone sees what they see, hears what they hear and knows what they know
- not intentionally selfish as their world is self centred and might get angry if they don’t get their way
- animism
- tendency of children to believe that all objects and animals are living and capable of feelings and emotions
- believes that objects have the same feelings they do
- centration
- occurs when child only pays attention to a small range of aspects when observing a stimulus
- may pay attention to the height of an object and not its mass
concrete operational stage
thinking logically and carrying our mental operations with concrete materials but not with abstract ideas
concepts of concrete operational stage
- conservation
- understanding that the mass of an object remains the same even if its shape or appearance changes
- requires child to observe transformations in physical quantities that are initially equivalent and then the transformation
- classification
- ability to group sets of discrete items into a broader category
formal operational stage
- adolescents develop ability to think about and solve abstract problems in logical manner
- reasoning based on logic that includes abstractions and systematic thinking about hypothetical events
- able to understand double meanings and proverbs
concepts of formal operational stage
- logical thinking
- develop strategies to work through problems systematically, identify and hypothesise about various solutions to problems and systematically test solutions
- abstract thinking
- thinking that does not rely on being able to handle or see concrete materials in order to reason about them
three mountain task
- tests egocentrism
- uses apparatus called diorama involving 2 model mountains made of paper mache of different sizes, shape and colour and different landmarks on top
- first child is asked to walk around and familiarise with the diorama
- second child was asked to sit facing 3 mountains and a doll was placed behind the first mountain
- the child was asked ‘what can the doll see’ and were shown several pictures of the mountains from different viewpoints, one of which was the actual viewpoint of the child
- process was repeated with the doll in front of the second mountain and then the third
- the child was asked the same question and was required to select a picture
- Piaget found that children up to 7 years old chose the picture that showed what they could see
- seeing things from different perspective occurs at a later age when children stop centering on themselves
Martin Hughes
- policeman task
- children 3.5 to 5 years old could take another’s perspective
- no longer egocentric when asked to carry out task involving hiding a boy doll so that policeman can’t see him
- children were shown a model comprising 2 intersecting walls and then placed the policeman doll in several positions and asked child to hide the boy doll from the policeman
- very few mistakes were made as children were asked if they understood what was being asked of them
- second policeman doll was brought in and both policeman dolls were placed at end of 2 walls and child was asked to hide boy doll from both policemen
- 90% gave correct answers showing that children lost their egocentric thinking by 4 years old because they were able to take another’s perspective
