a person's sexual orientation from their eyes. Pupils, that is. According
to Stephanie Pappas, a new study finds that pupil dilation is an accurate
indicator of sexual orientation. When people look at erotic images and
become aroused, their pupils open up in an unconscious reaction, which gave
researchers a much easier way to to study orientation and arousal without
traditionally invasive blood flow to the genital measurements.
Researcher Ritch Savin-Williams, a developmental psychologist at Cornell
University, says the new study is the first large-scale experiment to show
that pupil dilation matches what people report feeling aroused by.
"So if a man says he's straight, his eyes are dilating towards women," Savin
-Williams told LiveScience. "And the opposite with gay men, their eyes are
dilating to men."
Savin-Willims told Live Science that the pupils dilate slightly in response
to any exciting or interesting stimulus, a sign that the autonomic nervous
system — the system that controls involuntary actions like pulse and
breathing — is ramping up.
Savin-Williams and fellow researcher Gerulf Rieger had 325 men and women who
idetified as gay, straight, or bisexual watch one-minute videos of a man
masturbating, a woman masturbating, and neutral landscape scenes while a
camera measured tiny changes in their pupil sizes.
The results, according to Live Science, showed that pupil dilation matches
the pattern seen in genital arousal studies. In men, this pattern is
generally straightforward: Straight men respond to sexual images of women;
gay men to sexual images of men; and bisexual men to both men and women. But
women's responses were more complex, said Savin-Wiliams, because while
lesbians responded to images of other women, straight women "dilate
basically equally in response to erotic images of both sexes, despite
reporting feelings of arousal for men and not women."
Whether there's a host of closeted bisexual women or another evolutionary
answer to this straight girl dilation, it gives researchers a complex result
to try to unravel. | p****u
