Developmental Psych Flashcards
What is developmental psychology?
The study of what changes and what stays the same, across different periods of life
Two central questions
- What development happens in stages and what happens continuously
- How do nature and nurture influence development
Qualitative development
Stages, you can see a change in quality
Quantitative development
Continuous, development bit by bit
Nature and nurture
- What we inherit
- What we experience
Interplay between these two
Nature and nurture driven similarities
All humans share as they develop (e.g. pre-installed reflexes or hearing speech during a critical period)
Nature and nurture driven differences
Vary from person to person with development (e.g. birth weight or crawling development)
Reflexes
Automatic patterns of motor responses triggered by some type of sensory stimulation
Baby reflexes
Rooting reflex, sucking reflex, grasping reflex
Habituation
Decreased response to a repeated stimulus
Novelty-preference procedure
Demonstrates infants ability to perceive and respond: present –> observe habituation –> present old or new
Dishabituation
Increased response to new stimulus after habituating to the old
Motor development
Changes in the ability to coordinate and perform bodily movements
Rules for motor development
Head –> toe and centre –> periphery
Discipline of cognitive development
Changes in mental activities associated with thinking, knowing, remembering, and communicating
