Face Perception & Motor Development Flashcards
Perceptual narrowing
developmental process characterized by a diminished ability to distinguish among less frequently-encountered stimuli
ex: own-species vs other-species; own-race vs other-race
absolute threshold
minimum sound level of stimulus to detect a sound
relative threshold
minimum difference in loudness or pitch to discriminate between sounds
do newborns prefer hearing speech more than non-speech sounds?
Yes
they prefer a mother voice’s over a stranger’s voice
“baby talk” over adult-directed speech
music perception
infants share the strong preferences adults have for some musical sounds over others
consonant
pleasing to the ear
dissonant
unpleasing to the ear
at what age do babies prefer music of their own culture
4 motnhs
William Thierry Pryer
english physiologiat who systematically document changes in his own son’s motor skills from birth to 3 years of age
proposed a common and universal sequence of motor development across species
gessell and motor milestone
american child psychologist who tracked the motor behaviours and physical growth of 107 infants between 4-56 weeks
maturation
genetically determind process that controls and preseves the order of behaviours and skills as children develop
what claims were maturation based off of
two twins were studied, one was trained and one was not
mrytle mcGraw and motor practice
trained one twin while the other remained in crib.
trained twin showed early performance on specific motor skills that were trained
Esther Thelen and Dynamic Systems
- dynamic systems: considers the many interacting forces that influence infants’ motor skills, beyond “top-down” brain explanations
-stepping reflex: newborns will show stepping behaviours as if they are stepping or walking but will disappear in 4 months
traditional idea
the reflex was controlled subcortical brain areas, it wasn’t under the infant’s conscious control (automatically happens)
