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?

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

fine motor skills

motor development involves many distinct skills that are organized and reorganized over time to meet demands of specific tasks
