Chapter 5 Flashcards
do babies prefer a novel stimulus?
yes
auditory threshold
quietest sound that a person can hear
do infants hear as well as adults?
no
what is the main cause of hearing impairment in infants?
heredity
what are cones for
how we detect wavelength and colour
when can infants see all colour?
3 months
intersensory redundancy theory
infants perceptual system is attuned to amodal info that is present to multiple sensory modes
size constancy
realization that objects actual size remains the same despite changes in size of its retinal image
visual expansion
as objects move closer, it fills a greater portion of retina
this is why we flinch if someone throws a ball at us
motion parallax
nearby moving objects move across visual field faster than those at a distance
retinal disparity
right and left eye see slightly different versions of same scene
configural processing
can distinguish between same features but different configuration
featural processing
can distinguish between different features
what are the 3 networks/elements of attention?
orienting
alerting
executive
orienting network
determines which stimuli will be processed further and which will be ignored
alerting network
keeps childs attentional processes prepared, ready to detect and respond to stimuli
executive network
responsible for monitoring thoughts, feelings ,responses and resolving conflicts
what is the most complex element of attention?
executive network
which network/element of attention is the slowest to develop?
executive network
what are the 3 symptoms of ADHD
hyperactivity
inattention
impulsivity
what are treatments for ADHD
stimulant drugs like ritalin
psychosocial treatments
motor skills
coordinated movements of muscles and limbs
what are 2 challenges of motor skills
locomotion
fine motor skills
dynamic systems theory
motor development involves many distinct skills that are organized and reorganized over time to meet demands of specific tasks
when do children start stepping spontaneously
10 months
mastering intricate motions require what 2 things?
differentiation
integration
are children with active parents more active?
yes
when do kids pick a preferred hand?
after one year
what influences handedness (left/right handed)?
genes and experience
experience because modern culture favours right handedness
what do newborns prefer in regard to facial features? (3 things)
attractive faces
upright faces
normal features
whats a very important cue?
motion
which cones are sensitive to short wavelength
blue and violet
which cones are sensitive to long wavelength
red and orange
do babies hear sounds best that have pitches in the range of human speech?
yes
when can a baby recognize their own name?
4 1/2 months
