Sensory and Perceptual Development
_____% of 5 yo have two point discrimination, and by ______ yo a child should have it. -
correct answer-50%
7.5 yo
acuity - correct answer--sharpness of sight
-snellen eye chart for adults
-can be tested in children at 1 yr
aspects of object perception - correct answer--objects attributes are based on size, shape,
and motion
-perception based on information about edges
-Figure and ground (objects of interest seen as distinct from background); develops around
4-6 yo and fully develops around 6-8 yo
-Whole and part: Parts of a picture or object discriminated from whole, yet can be integrated
-Parts and whole perceived simultaneously
-children <9 can only see bigger picture
auditory development over time: - correct answer-newborns: turn in direction of sound
-1-4 mo: discrimination of basic sounds
-3 mo: infants hear low frequencies but not high pitches
-6 mo: hearing is similar to adult
-3 yrs: children can locate distant sounds
-3-5 yo: accuracy in discrimination improves
-13 yo: still refining auditory differences
body awareness: laterality - correct answer--body sides are distinct
-reached by 4-5 yo
-right vs left
-can identify but struggle with application (turn left three steps, then right)
-show adult like responses to laterality by 10 yo
-hand dominance occurs at 4-6 yo
common impairments for visual acuity - correct answer-esotropia
exotropia
amblyopia
development of shape and orientation perception - correct answer--Newborns are sensitive
to object shape
-Newborns perceive faces
-Children refine their ability to detect subtle changes in object orientation
development of space perception - correct answer--by 6 months, infants perceive depth
-depth is refined to adult like levels in adolescence
