Intentional Communication Flashcards
What is intentional communication?
Communication that has a discernible topic
orientated to real objects or events
Denotive or about something
e.g. pointing, words, lifting arms to be picked up
What is pre intentional communication?
Expressive - purposeful
e.g. crying, laughing, babbling
What are the 3 types of early communication development?
Vocal gestures - production (non speech, vocal communication e.g. crying and laughing) and perception (phonemic discriminations)
Manual - pointing, begging
Development of intentional communication
0-2 months- shared alertness, not separated from mother, object is separate
2-6 - early dyadic communication, mother and infant communicate with each other
6+ - joint object involvement, mum, infant and object all interact together
9-10 - can fixate pointing
11-13 - productive pointing but don’t bring in caregiver
14-15 - productive pointing, looking at caregiver first then pointing
Pointing to request (protoimperative)
Goal directed behaviour (reaching), turning to mother (attention seeking), waiting for a response, points to object, so mum gets it
Have a goal before actions, use visual and auditory actions to get mother, altered gaze from the referrent (apple) to recipient (mother) - persist and repeat signals if recipient doesn’t respond
means end reasoning -use of social partner - means = caregiver ends = attainment of object
Pointing to comment (protodeclarative)
Pointing towards an unknown referent
Point to event, look at mum, look back and forth between these
What are the two interpretations of protodeclarative pointing?
Lean interpretation - trying to get a response from caregiver, mean is the distant event, end=response from caregiver
Rich interpretation - child is aware that mother has a separate psychological perspective, uses pointing to influence mothers mind
goal = joint attention to object, belief that children have a TOM as young as 12 months old
What are the 3 perspectives on pointing?
The nativist theory
Cognitive or representational view
Learning theory
Nativist theory
Butterworth - human index finger pointing is biologically based and species specific, it is an evolutionary adaptation as a reference in humans - use gestures before words
Hand anatomy of chimps and humans - chimps have very small thumbs but long fingers so thumb sits far from fingertips. Humans use precision grip, tips of thumb and index finger held together whereas chimps use thumb and curl index finger - power grip. Butterworth thought these differences in grip contribute to pointing differences
Evidence to support nativist theory
Apes do not point in the wild, it is rare if they do
they mostly point with their whole hand
Human hands are biomechanically poised for index finger extension - when relaxing hand, index finger sits above other fingers but in chimps, all fingers are lined up with each other
Principle of antithesis
Opposite body postures express opposite emotions - develop from a power grip to precision grip between 6-20 months of age
Critique of nativist
Language trained apes can point with their index fingers - depends on rearing
Pointing with whole hands is a human behaviour too, despite the hand differences, there is no physical impairment to pointing in chimps - posture of hand doesn’t reflect cognitive capacity
Cognitive view
Humans have shared attentional modules, evidence = gaze monitoring and pro declarative pointing, means infants understand others as intentional agents with intentional and attentional agenda
Gestures influence others state of mind, so we must understand others - early indicator of TOM
Experiment on cognitive view - Liszkowski et al
75 babies, 12 months old Sit in front of window 4 conditions: joint attention (experimenter is positive and looks) face (positive emotion but doesn't turn) event (looks over but neutral face) ignore
If joint attention = babies are less likely to repeat pointing, satisfied. evidence that babies understand attention and psychological perspective of others
Moore
But, could be learning, infant knows that the point leads to a head turn and response from an adult. pointing infants will expect head turns and affective responses, infants repeated point in other conditions hoping to obtain the desired response
