Transcript Choice Blindness In Males & Females

Choice Blindness In Males and
Females
Lilly Tinsley and Vanessa Shadare
Choice Blindness
• Choice blindness is a form of inattentional
blindness, a phenomenon in which people fail
to notice unexpected stimuli in the world
around them.
Hypotheses
• Null Hypothesis: There is no difference in
choice blindness between males and females.
• Alternative Hypothesis: There is a difference in
choice blindness between males and females.
Methods
• 15 male and 15 females will be test
subjects.
• Present two photos side by side
and ask the test subject to tell
which person they find more
attractive.
• Remove photos and re-present
them with either their selection or
or an alternative photo.
• Ask the subject to justify their
choice.
Methods cont.
• Repeat previous steps ten
times with each test subject
using different pairs of
faces.
• The same protocol will be
followed with various
scents instead of faces.
Analysis
• We are going to
compare results
among genders
and senses.
• Sign tests and
tests of
heterogeneity will
be employed.
Results
• After collecting data, we
confirmed that our null
hypothesis is correct
– There is no difference in
choice blindness between
males and females
– The amount of choice
blindness exhibited by males
and females is not significant,
as determined by a sign test
