Men are more distracted by sexual images than women

Two experiments conducted on young people in the United Kingdom found that men are more distracted by sexual images than women. In all conditions, participants were slower to make decisions when exposed to sexual images. The research was published in Sexes.

Stimuli that evoke emotions tend to capture attention and trigger quicker reactions. For instance, forming a first impression of someone might take several seconds, but determining whether a person poses a threat takes less than a second. People generally respond more rapidly to threatening images than to non-threatening ones.

Similarly, sexual images can also trigger emotional reactions and alter attention and response times in a way comparable to threatening stimuli. Some studies have identified what is called a “sexual content-induced delay.” For example, in one study, participants were asked to decide whether a string of letters formed a real word. Results showed they took more time to classify sexual words than non-sexual ones. This delay likely occurs because sexual images capture cognitive priority, distracting individuals from other tasks.

Study author Robert J. Snowden and his colleagues aimed to examine how the presence of sexual images affects performance in a simple perceptual task—specifically, comparing the orientation of two lines. They hypothesized that sexual images would produce a delay in processing the task. The researchers also wanted to explore whether the magnitude of this effect differed between men and women, and whether it changed depending on whether the sexual image matched the participant’s preferred gender. Two experiments were conducted.

Participants in the first experiment included 43 young adults recruited via advertisements around the School of Psychology at Cardiff University in the United Kingdom. The average age was 22, and 22 participants were women.

Participants completed a line orientation perceptual task while being shown various images (which they were instructed to ignore). Ten of the images depicted heterosexual couples engaged in sexual activity, ten showed nude or partially dressed women who were not sexually active, ten showed nude or partially dressed men who were also not sexually active or aroused, ten contained people in neutral settings (e.g., people working or shopping), and ten depicted objects (e.g., clocks, boats, gardens). All images were converted to grayscale. Each participant completed 150 trials, with each image appearing three times. Participants also reported their sexual orientation.

The second experiment included 131 young adults, all students at Cardiff University; 58 were women. The overall setup was similar to the first experiment. However, this time, researchers used five images of nude or partially dressed men, five of nude or partially dressed women, and twenty neutral images. Unlike in the first experiment, where the image and task remained onscreen until the participant responded, the presentation time in the second experiment was limited to 150 milliseconds—short enough to prevent participants from shifting their gaze.

As expected, participants’ responses were slower when sexual images were shown. In Experiment 1, this slowing effect was more pronounced in men than in women. The delay was greatest when the image depicted a couple engaged in sexual activity.

In Experiment 2, the magnitude of the slowing effect in men depended on whether the sexual stimuli matched their gender preference. In other words, men’s responses were slowest when the image depicted a woman, faster when it depicted a man, and fastest when the image was neutral. Among women, the slowing effect was similar regardless of whether the image showed a man or a woman, although their responses to neutral images remained faster.

“The study demonstrates greater sexual distraction effects in men than women in a simple perceptual decision task. Furthermore, the distraction effects for men were shown to be category-specific (with a greater distraction from images of females), whereas those of women appeared to be category-non-specific,” the study authors concluded.

The findings shed light on how sexual imagery affects cognitive processing. However, it’s important to note that all participants in the study were young university students. Results may differ in other age or demographic groups.
