Facial resemblance between couples
Couples who originally bore no particular resemblance to each other when first married had, after 25 years of marriage, come to resemble each other, although the resemblance may be subtle, according to a new research report. Moreover, the more marital happiness a couple reported, the greater their increase in facial resemblance. The increase in facial similarity results from decades of shared emotions, according to Robert Zajonc, a psychologist at the University of Michigan, who did the research. In the study, people were presented a random array of photographs of faces, with the backgrounds blacked out, and were instructed to match the men with the women who most closely resembled them. Two dozen of the photographs were of couples when first married; another two dozen were of the same couples 25 years later, most taken around the time of their silver wedding anniversary. All the couples in the photographs were white, lived in Michigan or Wisconsin and were between 50 and 60 years old at the time of the second picture.
