semantic representation of language Flashcards

1
Q

the chinese room problem

A

can translate to other symbols > still arbitrary and don’t understand meaning
when given pictorial stimuli - makes sense

Q

amodal symbol system

A

experience transduced into abstract symbols

- predicts language is processed in a central processing unit

Q

problem with amodal symbol system

A
  • symbols not different from eachother
  • symbol grounding problem
  • no rule saying what symbol should be used for what object

Q

symbol grounding problem

A

symbols not grounded in anything = no meaning

no constraint to force it to refer to a particular things

Q

embodied cognition theory

A

mental representations are different experiences with object
different senses represented in different brain areas
lots of peripheral system supporting it
predicts language interacts with perception and action

Q

benefit of embodied cognition theory

A

address symbol grounding problem

- physical constraint - if image in mind and real life = similar > match

Q

reading vs sensory perception study

A

sentence - picture verification task
(Ps presented sentences then pics, asked if pic in sentence)
2 sentences (john put pen in cup/drawer)
2 pen orientations (vertical/horizontal)
faster response when match
- preactivation of particular neuron - priming

supports embodied
amodal would predict would make no difference

egg in a pan = cooked
faster when match

Q

reading vs body movements study

A

Ps read sentence describing action then must perform action
sentences = open/close drawer
action = yes above or yes below

faster response when match
- preactivation of particular neuron - priming

supports embodied
amodal would predict would make no difference

Q

reading vs body movements - BRAIN

A

part of brain activated when read action words = part of motor cortex corresponding to it (fMRI)

distributed in brain - supporting embodied

Q

TMS - reading vs body movement BRAIN

A

single pulse TMS administered and measure muscles using MEP
stimulation to different areas of motor cortex = different depending on action word read

after reading about hand/foot - MEP smaller in that area
as engages hand/foot system - interfering with MEP

Q

reading and multimodal experience

A

read short narratives
coded change in information
found different changes involve different brain areas

Q

character involves

A

temporal and parietal-temporal junction

17
Q

goal involved

A

parietal and frontal

18
Q

object involves

A

dorsolateral prefrontal and occipital temporal

19
Q

time involved

A

midfrontal and prefrontal

20
Q

Parkinson’s processing action words

A

literal and metaphoric verbs parkinsons patient slower to process then control verb
idiomatic parkinsons no difference to control verb (normal people faster)

impairment in understanding action words and in making actions
supporting embodied as brain must stimulate these areas in understanding

21
Q

future research

A
  • is all meaning represented in embodied? (numbers?)
  • abstract concepts? no physical entity (amodal required?)
  • how flexible is mental stimulation?
22
Q

Embodied theories have difficulties in explaining abstract language representations because:

A

not directly mapped to 5 senses

no physical entity
