Development of the Self Flashcards
what does cognitive neuroscience suggest about body representations?
body representations are multisensory perceptions involving the integration of a range of different sensory inputs.
these are crucial for perceiving the self and the environment
what is touch?
the first, and most bodily sense
when can responses to touch be seen?
before 7w gestation
understanding the development of tactile perception is crucial to understanding the development of the bodily self
how does gallagher (2005) use evidence to suggest there are innate body representations
evidence of phantom limbs in congenital aplasia. however, we should look earlier in development, as this is rare and controversial
meltzoff (1977) and neonatal imitation
infants have ‘active intermodal mapping’
- uses multisensory maps to match tactile facial configurations to their own movement
issues with using neonatal imitation as evidence of innate body representations
replications of neonatal imitation for gestures other than tongue protrusion are not reliable, as even tongue protrusion occurs under a range of circumstances, e.g., arousal.
what does newborns’ ability for hand-mouth coordinaton suggest?
there is an “innate” bodily self, however this does not consider their prenatal environment.
evidence of newborns responding differently to self-touch vs. touch by others at 1m is very weak.
when are somatotopic cortical responses present?
at 30w gestation, but it is unclear whether this adds to understanding of body representations or just somatosensory responses to touch
where is clear evidence that infants have body representations at birth?
young infants are sensitive to multisensory visual-tactile correspondences and audio-tactile colocations by 4m
when does tactile enhancement of visual limb processing develop?
between 4-8m (rigato, 2014)
what did bremner (2008) find about developing body representations?
infants cannot demonstrate the ability to locate touch in external space until 6m.
they continue to develop the ability to localise touch on the body by coordinating eye movements,
and track their limbs across changes in posture by 10m vs 6.5m
what does the rubber hand illusion show?
shows how body representations are fine-tuned during childhood, as children demonstrated a stronger RHI than adults between 4-9y (Botvinick and Cohen, 1998).
why did infants display a stronger RHI than adults?
is because they rely more heavily than adults on the visual sense of the body
when did adults show a greater RHI drift?
during synchronous stroking vs asynchronous stroking
when can early origins of the interpersonal self be seen?
in periodicity in infant-parent protoconversations, and possibly also early imitation.
however, there are doubts whether this reflects self-awareness
