Developmental Psych Flashcards
What are the three stages of human embryonic development?
1 germinal stage
2 embryonic stage
3 fetal stage
what is developmental psychology?
the study of changes and transitions that accompany physical growth or maturation
what are the five major reflexes of the neonate?
- sucking
- head turning
- Moro
- Babinski
- Palmar
What is the Moro reflex?
a neonatal reflex - throwing out the arms and legs, then bringing them together again in response to frightening noises
What is the Babinski reflex?
a neonatal reflex - fanning the toes when the bottom of the foot is stroked
What is the Palmar reflex?
a neonatal reflex - grasping objects that touch the hand
What were the two mechanisms of Piaget’s adaption?
- assimilation
- accommodation
What does assimilation mean in terms of developmental psych?
fitting new info into existing ideas and schemas
What does accommodation mean in terms of developmental psych?
modifying cognitive schemata to incorporate new information
What were Piaget’s 4 stages of development?
- sensorimotor
- pre-operational
- concrete operational
- formal operational
What are the four behavior types in Piaget’s sensorimotor stage of development?
- reflexive behavior cued by sensations
- circular reactions
- object permanence
- acquiring representation
What is a circular reaction?
a repeated behavior intended to manipulate the environment
What is object permanence?
knowing an object continues to exist even when it can no longer be seen
What does representation (in the context of sensorimotor stage development) mean?
visualizing or putting words to objects
What are the key characteristics of Piaget’s preoperational stage of development?
- rapidly acquiring words & symbols
- egocentric understanding of things
- poor ability to perform mental operations (causality, quantity)
What are the key characteristics of Piaget’s concrete operational stage of development?
- understanding of concrete relationships (quantity, simple math)
- understanding conservation of quantity
What are the key characteristics of Piaget’s formal operational stage of development?
understanding abstract relationships such as logic, ratios, and values
What did Piaget hypothesize about language development?
that it was dependent on the cognitive stage of the child
