Chapter 5: motor, sensory, and perceptual Development Flashcards
dynamic systems theory
infants assemble motor skills for perceiving and acting
motor behaviors are the result of…
body’s physical properties, nervous system development, the child’s goal and environmental support
reflexes allow infants to…
respond adaptively to the environment before they have had the opportunity to learn.
rooting reflex
when an infant’s cheek is stroked or the side of the mouth is touched, the infant turns its head and tried to find something to suck
sucking reflex
occurs when infants suck an object placed in their mouth
moro reflex
a startle response to sudden, intense noise or movement (ie. newborns arch their back or throw back their head)
grasping reflex
infants tightly grasp any object placed in their palm
gross motor skills
involve large-muscle activities, such as moving one’s arms or walking
development of gross motor skills requires…
requires postural control
dynamic processes are linked with… (3)
- sensory information in the skin, joints, and muscles to sense where we are
- vestibular organs to regulate balance
- vision and hearing
which 2 things are linked to learning to walk and sitting upright?
locomotion and postural control
in the second year of life infant are able to…
explore the environment more extensively and initiate social interactions
infants’ development of a skill requires…
considerable behavioral flexibility
boys usually outperform girls in ________
gross motor skills
girls usually outperform boys in ______
fine motor skills
decline in general biological functioning begins at the age of ___
30
leading cause of injury death in adults 65+
Falls
fine motor skills
involve finley tuned movements, such as any task requiring finger dexterity
palmer grasp in infants
grasp with whole hand
pincer grip in infants
grab small objects with thumb and forefinger
perceptual-motor coupling is necessary to…
coordinate grasping
the improvement of fine motor skills is supported by…..
increased myelination of the central nervous system
children begin to show manipulative skills such as complex, intricate, and rapid movements similar to the abilities of adults at ages….
ages 10-12
