Brain and Language Flashcards
(52 cards)
Reflexes are
preprogrammed, involuntary, stereotype, responses to specific stimuli
Newborn reflexes
grasping, rooting, sucking, stepping, swimming, moro (startle), babinski (stroke side of feet, toes will fan out), tonic neck (if you turn the babies head that side of their body will extend)
When do newborn reflexes disappear?
By the end of first year (2-6 month range)
What shift in control happens?
Subcortical to cortical structures
What is SIDS?
Unexplained death that occurs from birth to 1 year
When is SIDS at the highest risk?
2 to 6 months
Triple Risk SIDS Model
- Critical period of development when moving to cortical structures 2. Individual underlying vulnerability 3. environmental challenge to breathing
Risk factors for SIDS
stomach sleeping, soft mattresses, cigarette smoke, low birth weight, bed sharing
COL 1. Phonology
phonemes- fundamental units of sound in a given language and rules for combining them
COL 2. Semantics
meanings of individual words and combinations
COL 3. Grammar
rules about language structure, morphology, morpheme- fundamental unit of meaning and rules for combining to build words, syntax- rules for combining words into sentences/phrases
COL 4. Prosody
patterns of intonation, stress, etc, rhythmic aspect of language can convey meaning
COL 5. Pragmatics
social conventions around language use
PS 1. Perception
innate sensitivity to language, newborns prefer speech sounds, young infants “universal listeners”, by 10-12 months specialize
PS 2. Production
6-8 weeks cooing, 3-6 months babbling, 9-10 months speech like babbling
PS 3. Gestures
proto imperative pointing (using a gesture as a command or request), proto declarative (gesture to show/invite interest and attention)
Habituation
gradual decline in response to a repeated stimulus
Dishabituation
recovery of response when stimulus changes
Slower Habituation is seen in
preterm, younger, low birth weight, some brain injury
Classical Conditioning
unconditioned stimulus, unconditioned response, conditioned stimulus, conditioned response)
Reinforcement
increases frequency of behavior. positive reinforcement: ADD increases behavior with an added reward, negative reinforcement: REMOVE increases behavior when something negative is taken away
Punishment
decrease frequency of behavior, positive punishment: ADDING something to stop a behavior, negative punishment: REMOVE something to stop a behavior
Imitation
present early in infancy, probably from birth (newborn facial imitation)
Differed imitation
behavior is modeled, stop, then chance to imitate
