Simon and Chabris Flashcards
what is the aim of this study
simon and chabris intended to investigate the nature of inattentional visual blindness
what was the method and design
lab experiment and independant mesures design
what are the 4 independant variables
1) p’s count passess made by black or white team
2) unexpected event person in gorilla outfit or lady with umberella
3) count how many passes made or count how many bounce passes and ariel passess made
4) if the video is transparent or opaque
what is the dependant variable
the number of participants in each condtion that noticed the unexpected event
what is the sample technique for this study
self selected sample
what is the sample for this study
192 participants equally distributed accross 16 conditons
what were the 3 questions particpants were asked
while you were doing the counting did you notice anything unusual?
did you notice anything other than 6 players?
did you see the goriila/ women
what were some of the controls
each 21 experimenters had written protocall
all p’s tested individually
duration of unexpected event was the same
both videos filmed the same way
how long were the videos
75 seconds
when did the unexpected event occur
between 44-48 seconds into the video
what were some of the results
54% noticed the unexpected even and 46% failed to notice
opaque condtion 67% transparent 42%
what are some of the conclusions
the level of inattentional blindess depends on the difficulty of the primary task
objects can pass through the spatial extent of attentional focus and still not be ‘seen’ if they are not specifially been attended too.
key theme question
who-192 participants almost all undergraduate students from harvard univeristy
what- investigate the nature of inattentional visual blindness
how- watching a video with a task of counting basketball passes and unexpected event of gorilla or women with umberella
findings-54% noticed the unexpected event and 46% failed to notice it
area question
principle-interested in mental processing and looks at input, process and output in order to understand this #
aim- simon and chabris aimed to investigate the nature of inattentional visual blindness
findings-out of 192 participants 54% noticed the unexpected event and 46% failed to notice the event.
