Ch.5 Motor, Sensory, & Perceptual Development

Front 1

Esther Thalen, infants coordinate multiple skills or abilities to meet a motor goal

Back 1

Dynamic Systems Theory: Soft assembly

Front 2

Esther Thalen, result from a combo of motivation and learning to assemble the needed components

Back 2

Dynamic Systems Theory: New skills

Front 3

Esther Thalen, constant modification of assembly patterns

Back 3

Dynamic Systems Theory: Adaptation

Front 4

Toes stretch out, fan, and curl due to rubbing the bottom of the foot.

Back 4

Temporary reflex: Babinski reflex

Front 5

Infant has strong grasp, fingers and thumb wrap around object tightly, until grip is broken

Back 5

Temporary reflex: Palmar reflex

Front 6

Adaptive response , give infant feeling of being dropped or falling. Respond by throwing arms out to the side, pull them into middle of body, and head goes to midline

Back 6

Temporary reflex: Moro reflex

Front 7

Press object into foot, toes curl around object and grip

Back 7

Temporary reflex: Plantar reflex

Front 8

Beneficial with feeding behavior, stroke babies cheek close to mouth and baby will open mouth wide and turn towards stimulation, preparing to eat. *Don't only root in feeding situations

Back 8

Temporary reflex: Rooting response

Front 9

Put something in babies mouth and they will suck on it

Back 9

Temporary reflex: Sucking response

Front 10

Put babies weight on it's feet and it engages in stepping motions. Not all weight is placed on the feet.

Back 10

Temporary reflex: Stepping reflex

Front 11

Large muscle activities requiring postural control

Back 11

Gross motor skills

Front 12

Holding body and head upright

Back 12

Postural control

Front 13

Finely tuned movements that require finger dexterity

Back 13

Fine motor skills

Front 14

First major motor development

Back 14

Learning to walk

Front 15

Stepping movements, alternating leg movements, development of: postural control, muscle strength to support body weight, ability to balance on one leg long enough, and motivation

Back 15

Gross Motor Development at Birth

Front 16

Build on walking skills (1-2 years), running, walking backward, maneuvering stairs, coordinated enough for sports

Back 16

Gross Motor Milestones Beyond First Year

Front 17

Peak physical performance at 19-26 years , decline begins at about age 30

Back 17

Gross Motor Skills in Adulthood

Front 18

Main issue is slowed movement

Back 18

Gross Motor Skills and Aging

Front 19

No fine motor control at birth, reaching and grasping objects allows for finger movement and whole hand movement

Back 19

Fine Motor Development in Infancy

Front 20

Improvements in precision, improvements in coordination (eye, hand, arms, and fingers all work together)

Back 20

Fine Motor Development in Childhood and Adolescence

Front 21

Becoming accustomed to a stimulus and getting bored with it

Back 21

Habituation

Front 22

Gaining interest in a stimulus, re-orienting, re-engaging

Back 22

Dishabituation

Front 23

Tests infants' perception of depth , fear of heights. New crawlers intrigued by heights, experienced crawlers afraid of heights.

Back 23

Visual Cliff Experiments

Front 24

Lens thickens, visions become cloudy or distorted, treated by glasses, surgery (but these tend to regrow)

Back 24

Cataracts

Front 25

Fluid builds up in the eye, puts pressure on optic nerve and causes damage, treated with eye drops

Back 25

Glaucoma

Front 26

Deterioration of the retina, causes poor vision and blind spots, difficult to treat but laser surgery can work; but disease is progressive and retina continues to deteriorate

Back 26

Macular degeneration
