Female observers did not show different pupil responses to semi-naked and clothed stimuli or male and female targets. If this differentially affects the stimulus categories in the current study, then this could influence the measurement of pupil responses as an index of sexual interest. But straight women dilate basically equally in response to erotic images of both sexes, despite reporting feelings of arousal for men and not women. In 16th-century Italy, women would take eye drops made from the toxic herb Belladona, which kept their pupils from constricting and was thought to bestow a seductive look. A similar pattern is also found as an arousal response to pleasant and unpleasant stimuli Bradley et al. Back in the s, Charles Darwin linked the pupils to emotions such as fear or surprise. Are we attracted to dilated pupils?
Despite these promising results, there have been no attempts to replicate these findings until recently. While few studies have focussed on pupil dilation as a measure of sexual interest for photographs of adults, there has been even less research on pupillary responses to persons of different ages. Male observers demonstrated more pupil dilation to semi-nude women than any other stimuli. These characteristics might make pupillary response an ideal measure for the assessment of sexual interest. Female observers showed pupil dilation to photographs of men and women but not children. And then there's the invasiveness issue. One theory is that because women have been at risk of being raped throughout history, they evolved to respond with lubrication to any sexual stimulus, no matter how unappealing. This manipulation can decrease image quality by reducing light—dark contrasts. It's also a great way to make all of your surroundings 'fade to black' and concentrate on each other. The dilation is a sign that the autonomic nervous system — the system that controls involuntary actions like pulse and breathing — is ramping up. Swaminathan , VisionWeb ]. In two experiments, the pupillary responses of heterosexual adults to images of males and females of different ages were related to self-reported sexual interest, sexual appeal to the stimuli, and a child molestation proclivity scale. OK, so our pupils dilate when we're stimulated, but is it also going the other way around? But light isn't the only thing orchestrating when the pupils dilate or contract. A similar pattern is also found as an arousal response to pleasant and unpleasant stimuli Bradley et al. For females however, it's a little more complicated: However, the difference between these percentage fixations is not indicative of a sensitive measure of involuntary behavior. They recruited men and women, including gay, straight and bisexual participants. Traditionally, researchers have studied arousal and sexual orientation by asking volunteers to watch erotic movies or pictures while attached to instruments that measure blood flow to the genitals. Gay women show more pupil dilation to images of other women, similar to the pattern seen in straight men. About a century later, scientists discovered that pupils also pop when we experience emotions on the sunnier end of the spectrum. However, a subsequent experiment also recorded a pupil dilation effect in female observers that appeared to be related to sexual interest Hamel, Twenty measurements were obtained for each stimulus by manually measuring pupil diameter at each frame of the video footage. While this is an interesting possibility, the pupillary response to sexual arousal has received little research attention. The researchers detail their findings today Aug.
