What is global conciousness?
conciousness from everywhere. Not aware of everything but aware of specific things
1 of 20
What are the two proposed ways of creating coherent and meaningful consciousness?
a central manger selecting appropriate contents of awareness. and a brain process that organises themselves
2 of 20
Why is the central manager flawed?
no evidence. it isnt true. the loudest sound always drowns out others. visual pathways not a feed forward system. circuits in circuits. global conciousness architechture
3 of 20
What is the self organising brain?
proof of principle- mathmatics, complex coherant patterns emerging from simple oscilllating networks. re entrant links, architecture for global processing. to bring features together to form content (gamma synch)
4 of 20
Explain the role of gamma and synchronisation
gamma helps synchronise. brain areas conjointly involved in a task become gamma synchronised when the task is performed. mechanism for bringing features together forming content. but still dont know.

Do we react to what we percieve?
1) can only react to what we have conciously percieved. 2) we can only react selectively to something we have conciously percieved. (repition blindness, attentional blink, inattentional bline, change blindness
6 of 20
describe contrasting evidence for consciously percieving
visual neglect- not seeing what is left. damage to the right parietal cortex (stroke) consistantly ignores the left side of the world.
7 of 20
Explain the line bisection task
two lines, patient ignores the left side. implicit knowledge in intact.. conciousness awareness of the left side is impaired. not processing left stimuli
8 of 20
explain the blindsight
vision in a blindspot. lesion to the primary visual cortex causes scotoma (blindness in part of the visual field).
9 of 20
what is a scotoma
blindness in part of the visual field
10 of 20
what is subjective blindness?
reporting not seeing
11 of 20
what is objective blindness?
do not respond to stimuli in that area. (earlier stages of visual processing is still in tact)
12 of 20
What is residual blindness
processing in the blind area. Localisation task- patients only react to blind-field stimuli when prompted. insit they do not see the stimuli. correct guessing but no subjective sense
13 of 20
what is subliminal perception?
blindsight in normal observers. visual masking. 9different tasks, lexical, semantic and form decision)
14 of 20
what does visual masking do?
it can lower stimulus visibility until it becomes subjectively invisible or subliminal. processed at retinal level.
15 of 20
what is semantic priming?
speed at response to a word. target preeced by semantically related or non-related word. rime words.activate semantic association
16 of 20
what is subliminal semantic priming?
prime words masked prevent concious perception. therefore words not processed in isoclation. activates semantic associates. automatically without concopus.
17 of 20
what is contrasting evidence for selectively reacting to something we conciously percieve?
neglect implicit designs, blinsight but correct guessing, subliminal priming, semantic associations.
18 of 20
can we only control our responses to something we have conciously percieved??
semantic priming with polysemous words, disambiguious bias words. consitant/inconsistant target. we cannot selectively inhibit some
19 of 20
can we inhibit our responses to something we have concously percieved
yes. subliminal priming, mortor priming. prime first activates motor response.
