attention 3 Flashcards
Raymond, Shapiro and Arnekk 1992 attentional blink study procedure
- random letters appearing, had to find ‘x’ and distractor is a white random letter
- had to attend to another task while doing so
- distance between the x and white letter increases each time
results of Raymond shapiro and arnell 1992 study
- when asked to do 1 task scored above 80% correct
- when dual task, performance varies, 1/2 missed the ‘x’
- when doing it over 5 times performance increased
whats the ‘intentional blink paradime’
helps us to understand how attention works over time
what is inattentional blindness
where individuals fail to notice unexpected stimuli in their visual field when their attention is engaged in a primary task.
what is change blindness
where individuals fail to detect changes in visual stimuli, typically when those changes occur during a brief interruption, such as a flicker or a sudden movement.
- E.G A FLICKER
jensen et al., 2011 study found
types of failure- change and inattentional blindness
levin and simons 1997 study showed with images changing:
2/3 people did not notice
what did simons and levin 1997 find about moving eyes to different locations
- you dont take in information when moving your eyes
- you dont process info as well when your not interested
Rensink, O regan and clark 1997 study
- as images flicker on and off its hard to detect changes
whats the importance of interruption with example
- the image of plane with and without engine but flicker inbetween images makes it hard to detect whats changed
whats is Rensink’s 2002 coherence theory
suggests if change happens before we fixate it is harder to notice
what did Hollingworth and Henderson 2002 suggest
- over multiple fixations fairly less detailes representations are formed in LTM of several objects within a mental map
- which codes SPATIAL LAYOUT
- used eye tracking and showed that fixated objects showed greater change in detection
Jensen et al., 2011 study
- comparing what you represeneted from the target location before the change location to what there was after the change
- you conciously recognizze the discrepency
what did mack and rock 1998 say about change blindness
- the change occurs during an interutpion to viewing/attention
simons and chabris 1999 study with gorilla results
- when focusing on white team less than 80% ralised gorilla
- when focusing on black team more than 80% noticed gorilla
