26
Q

fine motor skills sequence (1 month - 12 months)

A
  • 1st month: pre-reaching reflex, grasp reflex
  • 3 months: intentional reaching
  • 4-5 months: reaching and grasping
  • 9-12 months: pincer grasp (thumb and forefinger)
27
Q

depth perception

A
  • ability to discern relative distance of objects from self in environment
  • requires binocular vision
28
Q

binocular vision

A

ability to coming the images of both eyes into one
- develops around 3 months

29
Q

intermodal perception

A

integration and coordination of sensory information (e.g. when they hear a sound they can turn to look for its source)

30
Q

Piaget’s sensorimotor substages (4)

A
  1. simple reflexes (0-1 month)
  2. first habits and primary circular reactions (1-4 months)
  3. secondary circular reactions (4-8 months)
  4. coordination of secondary schemes (8-12 months)
31
Q

simple reflexes

A

sucking, grasping, rooting (latching on to bottle or breast)
- more assimilation than accomodation

32
Q

first habits and primary circular reactions

A

actions start from unintentional action, but are repeated intentionally
- primary (focus on body) circular (repeated)

33
Q

secondary circular reactions

A

actions still start unintentionally, repeat actions in external world
- e.g. rolling a ball, pulling hair

34
Q

coordination of secondary schemes

A

actions begin as intentional goal-directed behaviour
- can coordinate schemes (move object to reach another)

35
Q

object permanence

A

awareness that objects continue to exist even when we can’t see or touch them
- develops around 8-12 months

36
Q

information processing approach

A
  • sensory memory (brief memory that retains impression of sensory information)
  • short term memory (information that is current focus of attention)
  • working memory (aspect of short term where info is stored as it’s comprehended)
  • long term memory (info that is committed to longer-term storage)
37
Q

habituation

A

gradual decrease in attention

38
Q

dishabituation

A

revival of attention with a new stimulus

39
Q

joint attention

A

ability to attend to what others are attending (looking and pointing at what others are looking at)
- develops by 12 months

40
Q

habituation measures

A
  • eye contact (how long?)
  • heart rate (how slow?)
  • sucking thumb (how fast?)
41
Q

recognition memory

A

recognising something as correct once its seen
- easier for babies
- e.g. the Chase when at the board

42
Q

recall memory

A

remembering something without hint
- e.g. the final Chase

43
Q

Gessell Scales (4)

A
  • motor skills
  • language use
  • adaptive behaviour
  • personal-social behaviour

produces developmental quotient (DQ)

44
Q

Bayley Scales (4)

A
  • cognitive
  • language
  • motor
  • habituation

suitable for 16 days - 3.5 months old
BSID-III Scale

45
Q

mozart effect

A

belief that listening to mozart made information retain better - led to creationg of educational videos and DVDs

46
Q

prelinguistic communication

A
  • cooing (ooh-ahhing) - 2 months
  • babbling (ba-ba-ba, da-da-da) - 4-10 months
47
Q

non-verbal communication

A

facial expressions, gestures pointing, imitation (8-10 months)

48
Q

infant directed speech

A
  • ‘motherese’ / baby talk
  • pitch and voice are higher
  • intonation exaggerated
  • infants prefer it
49
Q

A
  • Thomas and Chess
  • innate differences in the way in which individuals respond to the world around them
  • biologically based raw materials
50
Q

Thomas and Chess’ aspects of behaviour (3)

A
  • abilities: capacity to carry out behaviour
  • motivation: reason for performing behaviour
  • temperament: style in which they perform behaviour
51
Q

dimensions of temperament (6)

A
  1. activity level
  2. adaptability
  3. intensity of reactions
  4. quality of mood
  5. emotionality
  6. sociability
52
Q

A
  1. sensitivity
  2. activity level
  3. regularity
  4. intensity
  5. approach/withdrawal
  6. adaptability
  7. persistence
  8. distractibility
  9. mood
53
Q

goodness-of-fit

  • child’s behaviour and development shaped by interaction of temperament and environment
  • parents reactions/responses can strengthen or weaken infants persistence with temperament
54

  • disgust
  • surprise

58

A

infants learn to adapt and change their emotional reactions in response to others

59
Q

erikson’s infant stage

A

trust vs. mistrust

60
Q

Bowlby

A

evolutionary theory of attachment
- feeding is not the basis for attachment
- biologically preprogrammed to form attachments to survive

62
Q

  3. resistant
63
Q

three progressive stages of distress
