Chapter 5: Cognitive Development in Infancy and Toddlerhood Flashcards
Schemas
An understanding of how things are, not necessarily correct
Assimilation
Adapting schemas by including more information (learning all four legged animals are dogs from having a pet dog)
Accomodation
Adapting schemas by separating information (learning by seeing a cat that not all four legged animals are dogs)
Cognitive equilibrium and disequilibrium
When we don’t find new information to challenge schemas, the world is the way we know it
Sensorimotor substages
- Reflexes (birth - 1 month) - grasping
- Primary Circular Reactions (1-4 months)
- Secondary circular reaction (4-8 months) - repeating actions because they like how it feels
- Coordination of secondary circular reactions (8-12 months) - intentional behavior
- Tertiary circular reactions (12-18 months) - experiment with environment
- Mental representation (18-24 months)
Three methods for evaluating sensorimotor reasoning
Violation of expectation tasks, A not B tasks, deferred imitation tasks
Violation of expectation tasks
Mental representation capacities of very young infants, train isn’t stopped by the block covered by the screen, may happen sooner than 8 months
A not B tasks
Tests object permanence, motor skills, inhibition, and controlling attention. The baby understands the toy is under one mat, but once another mat was introduced the baby became confused.
Deferred imitation tasks
Imitation of facial expressions, unique actions, replicate something when asked. The infant needs memory ability to complete this.
Three types of memory and examples
- Sensory (touch, sight, hearing)
- Working memory (used to decide action, attention)
- Long-term memory
How is information encoded into memory?
Incoming information –> sensory memory –> working/active memory –> encoding –> long-term memory
Attention
Ability to direct awareness. We have the skill early on, but gain the ability to control it as we age.
How is attention measured in infants?
Preferential looking procedures
Memory
Recall of visual and auditory stimuli for neonates, recall of motor activities for infants. Familiar contexts and emotional engagement affect memory. At three months you can hold stimuli for a day.
Categorization
Infants create conceptual categories based on perceived function, behavior, and perceptual similarity. This includes learning that toys are not food.
