Which of the following explanations for the cross-race effect is most supported by empirical research?

a.
the cue-utilization hypothesis

b.
the unusualness hypothesis

c.
the interracial contact hypothesis

d.
the prejudice hypothesis

e.
the physiognomic homogeneity hypothesis

a. the cue-utilization hypothesis

The interracial contact hypothesis is most supported by empirical research as an explanation for the cross-race effect. This hypothesis suggests that people have more exposure and experience with individuals of their own race, leading to better recognition and memory for same-race faces compared to other-race faces. Studies have consistently shown that increased interracial contact can reduce the magnitude of the cross-race effect.
