When do primitive reflexes (moro reflex) appear? When do they disappear?

Present at birth and usually disappear between 3 and 6 months of age

2

What does it mean when an infant shows stronger and more-sustained primitive reflexes?

Central nervous system injury

3

Infants with CNS damage may have delayed development of ________ reactions

postural

4

Gross Motor Milestones

  • Birth:
  • 2 months:
  • 4 months:

  • Birth: Turns head to side
  • 2 months: Lifts head when lying prone, head lag when pulled from supine position
  • 4 months: Rolls over, no head lag, pushes chest up with arms

5

Gross Motor Milestones

  • 6 months:
  • 9 months:
  • 12 months:

  • 6 months: Sits alone, leads with head when pulled from supine position
  • 9 months: Pulls to stand, cruises
  • 12 months: Walks

6

An infant's fine motor skills progress from control over ______ muscles to control over ______ muscles

Proximal; Distal

7

What are the primitive reflexes?

  • Moro reflex: symmetric abduction and extension of arms with trunk extension
  • Hand grasp: reflex grasp of any object placed in palm
  • Atonic neck reflex: If head is turned to one side, arms and legs extend on same side and flex on the opposite
  • Rooting reflex: turning of head toward same side as stimulus when corner of infant's mouth is stimulated

8

What are the postural reactions, and when do they start?

  • Head righting: ability to keep head vertical despite body being tilted (4-6 months)
  • Parachute: Outstretched arms and legs when body is abruptly moved head first in downward direction (8-9 months)

9

What are the fine motor milestones?

  • Birth:
  • 3-4 months:
  • 4-5 months:

  • Birth: Keeps hands tightly fisted
  • 3-4 months: Brings hands together to midline and then to mouth
  • 4-5 months: Reaches for objects

10

Fine motor milestones:

  • 6-7 months:
  • 9 months:
  • 12 months:

  • 6-7 months: Rakes object with whole hand; transfers object from hand to hand
  • 9 months: Uses immature pincer (ability to hold small object between thumb and index finger)
    12 months: Uses mature pincer (between thumb and tip of index finger)

11

What is the earliest sign of neuromotor problems in development?

Persistent fisting beyond 3 months of age

12

What red flags in motor development indicate spasticity?

Early rolling over, early pulling to a stand instead of sitting, and persistent toe walking

13

Early hand dominance (before 18 months of age) may be a sign of...

weakness in the opposite upper extremity associated with hemiparesis

14

Delays in ______ development are more common than delays in other domains

language

15

When is the window of opportunity for optimal language acquisition?

first 2 years of life

16

What is the difference between language and speech?

  • Language: refers to the ability to communicate with symbols
  • Speech: The vocal expression of language

17

At what age are cooing and musical sounds expected?

2-3 months

18

At what age is there babbling? When are words first used?

6 months: babbling

12 months: 1-3 words (mama, dada)

19

By 18 months, a child should know __ - __ words

By 3 years, more than __% of the child's speech should be intelligible

By 18 months, a child should know 20-50 words

By 3 years, more than 75% of the child's speech should be intelligible

20

What is the prespeech period?

0-10 months: expressive language consists of musical like vowel sounds (cooing) and adding consonants to the vowel sounds; receptive language is characterized by increasing ability to localize sounds

21

What is the naming period?

10-18 months: Characterized by the infant's understanding that people have names and objects have labels

22

What is the word combination period?

18-24 months: Early word combinations are "telegraphic" (no prepositions, pronouns, articles)

23

Intellecutal development depends on what three things?

  1. Attention
  2. Information processing
  3. Memory

24

What is the single best indicator of intellectual potential?

Language

25

What are the 5 stages of cognitive development? When does each start?

  1. Sensorimotor period - Physical manipulation of objects (birth to 2 years)
  2. Stage of functional play (begins at about 1 year of age)
  3. Stage of imaginitve play (24-30 months)
  4. Concrete thinking (preschool and early elementary years)
  5. Abstract thinking (Adolescent years)

26

As a result of this ability to maintain an image of a person ______ _______ develops when a loved one leaves the room

9 months; separation anxiety

27

What is magical thinking?

A normal state of mind during the preschool toddler years when a child assumes inanimate objects are alive and have feelings
