Ch. 4: Cognition, Consciousness, and Language Flashcards
Explain Piaget’s stages of cognitive development.
- Sensorimotor - manipulating the environment to meet physical needs
- Preoperational - symbolic thinking, egocentricity, concentration
- Concrete operational - understanding feelings of others and manipulating physical objects
- Formal operational - abstract thought and problem solving
What is a mental set?
Pattern of approach for a given problem
What are heuristics?
Shortcuts used to made decisions
What are biases?
Exist when information cannot be able to objectively evaluate information
What is Gardner’s multiple intelligence theory?
Linguistic
Logical-mathematical
Musical
Visual-spatial
Bodily-kinesthetic
Interpersonal
Intrapersonal
What is the reticular formation?
nerual structure in brainstem that keeps the cortex awake and alert
What is electroencephalograpy (EEG)?
records electrical patterns within the brain during sleep
What are beta waves?
high frequency and occur when a person is alert or attending to a task that requires concentration
What are alpha waves?
occur when we are awake but relaxing with our eyes close
What occurs in stage 2 in sleep cycle?
theta waves with sleep spindles (bursts of high frequency waves) and K complexes (singular higgh amplitude waves)
What occurs in stage 3 in the sleep cycle?
slow-wave sleep (SWS)
slow EEG, only a few waves per seconds
delta waves
cognitive recovery, memory consolidation
What occurs in rapid eye movement (REM) sleep?
HR, breathing patterns, and EEG mimic wakefulness but individual is asleep
memory consolidation
where most dreaming occurs
What is the sequential order of brain waves?
BAT-D
1. beta
2. alpha
3. theta
4. delta
Explain melatonin.
sleepiness
decreated from the pineal gland and usually triggered be decreasing light (from retina)
Explain cortisol.
helps you wake up
produced in the adrenal cortex
