chapter seven: attention Flashcards
what is dichotic listening task
two different messages in each ear, only attend to one, person must ignore other message
what does dichotic listening task test
test what you are aware of in other message
what did donald broadbent do
coined early filter theory, filter only allows certain information through further processing in the brain
what is said about braodbent’s theory
not much is retained, but there is still aware of some stuff
what are people aware of (tentative)
physical qualities of sound, loud or soft and the rough pitch, woman or man sounding
what problems arise from this theory
the cocktail party effect
what is the cocktail party effect
different groups have different convos, but when name is heard in another group, you are aware of it
what did ann treisman discover
did the same tests as broadbent, but found that when something doesnt make sense, people borrow from unattended ear. created variation of filter theory
what did treisman say about her filter theory
instead of a filter that blocks, it is a filter that weakens. if something is meaningful enough, even if unattenuated, there is still awareness of it
where are these messages stored
the dictionary unity, the meaningful words you pay attention to when not attending, like name
what is late selection filter theory
all information is processed for meaning, only the most meaningful get through to further processing
what is cerebral lateralization
some abilities are more dependent on one side of the brain
what side is in charge of language
the left hemisphere of the brain
what side is in charge of spatial awareness
the right hemisphere
what did the bisection task conclude
when paying attention, we have a bias to the left side (left visual field is in the right side of brain and right visual field is in the left)
