If testing hypotheses about the effects of race on memory of faces, it would be most appropriate to calculate a.. 1)Independent- sample t-test 2)Paired sampled t-test 3) One- sample t-test 4) Z-test
Several researchers have found empirical evidence for a phenomenon known as the
"other race
effect" (ORE), where people are quicker and more accurate when identifying faces of their own
race, relative to faces from other races. A single group of 35 Caucasian participants were shown
a series of faces (50 faces were Caucasian, 50 faces were Asian) in a learning phase. Next,
participants were shown a total of 100 faces from each race, some of which were present in the
learning trials, Participants were asked to state whether or not a face was present or absent in
the learning trials. They compared the accuracy for memory of the Caucasian vs. Asian faces.
