Exam 2 Flashcards
Who was piaget and what did he do
he was one of the most influential development theorists of the 20th century
he carefully observed children(especially his own son) and used this info to form the theory that human cogntion develops not so much through traditional learning processes as through changes in the way children approach problems(believed that infants learn by doing)
piaget believed that all children pass through a series of universal stages in a fixed order. what are the stages
- sensorimotor
- preoperational
- concrete operations
- formal operations
during the stages, piaget believed that
- both quantity and quality of knowledge increase
- focus is on the change in understanding that occurs as child moves through stages
- movement through stages occurs with physical maturation & experience with environment
what are schemes
organized patterns of sensoriment functioning
what is assimilation
when people understand an experience in terms of their current stage of cognitive development & way of thinking
ex: sucking on every toy the same way or calling all animals dogs
what is accomodation
the change in existing ways of thinking that occur in respone to encounters with new stimuli or events
ex: sucking on things based on shape, calling all flying animals birds
what are the 6 substages on the sensorimotor stage of development?
1) Simple reflexes
2) 1st habits & primary circular reactions
3) Secondary circular reactions
4) coordination of secondary circular
5) teritary circular reactions
6) beginnings of thought
What happens in the 1st substage of the sensorimotor development
1) Simple reflexes
- 1st month of life
- various reflexes determine the infants interactions with the world
What happens in the 2nd substage of the sensorimotor development
2) 1st habits & primary circular reactions
- from 1-4 months of age
- coordination of actions
- circular reactions
- primary circular events occur
what is a circular reaction
an activity that permits the construction of cognitive schemes through reptition of a chance motor event
what are primary circular reactions
enjoyable actions on his/her body
What happens in the 3rd substage of the sensorimotor development
3) Secondary circular reactions
- 4-8 mnths
- begins to act on world
- secondary circular reactions
- vocalization increases & imitation
what are secondary circular reactions
repeated actions meant to bring about a desriable consequence on the outside world
What happens in the 4th substage of the sensorimotor development
4) Coordination of secondary circular reactions
- 8-12 mnths of age
- employs goal-directed behavior
- developemt of object permanance
what is goal-directed behavior
where several schemes are combined & coordinated to generate a single act to solve a problem
what is object permanence
the realization that people and objects exists even when they cannot be seen
What happens in the 5th substage of the sensorimotor development
5) Tertiary circular reactions
- 12-18 mnths of age
- tertiary circular reactions happen
what are tertiary circular reactions
they involve the deliberate variation of actions to bring describable consequeces
- minature “experiments” to observe consequences
- interest in understanding the unexpected
What happens in the 6th substage of the sensorimotor development
6) Beginning of thought
- 18-24 mnths of age
- capacity for mental representation
child gains ability to pretend and deferred imitation
what is mental represenation
an internal image of a past event of object
what is deferred imitation
in which a person who is no longer present is imitated by children who have witnessed a similar act
linguistic comprehnestion is the understanding of
speech
linguistic production is the use of language to
communicate
comprehension of language precedes
production of language
Understanding wha others means come before the ability to speech
infants show prelinguistic communication through
sounds, facial expressions, gestures, imitations & other non-linguistic means
1st words are general spoken between
10-14 months
what are holphases
one-word utterances that depend on the particular context in which they are used ti determine meaning
by 15 months, the average child knows about
15 words
between 16-24 months, the average child knows about
100 words
by 18 months infants are using telegraphic speech which means?
where words not critical to the message are left out
what is stranger anxiety
the caution & wariness displayed by infants when encountering an unfamiliar person
-appears in the 2nd half of the 1st year
infants with more experience with strangers tend to show
less anxiety
infants tend to show less anxiety with
female strangers and other children than males
what is seperation anxiety
the distress displayed by infants when a customary care provider deports
- usually begins about 8 or 9 months and peaks at 14 months
- starts slightly later than stranger anxiety
