“…To analyze the eyetracking data, eye movements were first preprocessed by combining fixations of less that 80 ms with the preceding or following fixations if these fixations fell within half a degree of visual angle (for similar approaches, see, e.g., Attard & Bindemann, 2014 ; Bindemann, Scheepers, Ferguson, & Burton, 2010 ). Fixations that fell outside the dimensions of the display monitor or that were obscured by eye blinks were excluded.…”

Comparing methods for the analysis of pupillary response

Changes in eye-pupil size index a range of cognitive processes. However, variations in the protocols used to analyze such data exist in the psychological literature. This raises the question of whether different approaches to pupillary response data influence the outcome of the analysis. To address this question, four methods of analysis were compared, using pupillary responses to sexually appetitive visual content as example data. These methods comprised analysis of the unadjusted (raw) pupillary response data, z-scored data, percentage-change data, and data transformed by a prestimulus baseline correction. Across two experiments, these methods yielded near-identical outcomes, leading to similar conclusions. This suggests that the range of approaches that are employed in the psychological literature to analyze pupillary response data do not fundamentally influence the outcome of the analysis. However, some systematic carryover effects were observed when a prestimulus baseline correction was applied, whereby dilation effects from an arousing target on one trial still influenced pupil size on the next trial. This indicates that the appropriate application of this analysis might require additional information, such as prior knowledge of the duration of carryover effects.

Pupillary Response as an Age-Specific Measure of Sexual Interest

In the visual processing of sexual content, pupil dilation is an indicator of arousal that has been linked to observers’ sexual orientation. This study investigated whether this measure can be extended to determine age-specific sexual interest. 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. In both experiments, the pupils of male observers dilated to photographs of women but not men, children, or neutral stimuli. These pupillary responses corresponded with observer’s self-reported sexual interests and their sexual appeal ratings of the stimuli. Female observers showed pupil dilation to photographs of men and women but not children. In women, pupillary responses also correlated poorly with sexual appeal ratings of the stimuli. These experiments provide initial evidence that eye-tracking could be used as a measure of sex-specific interest in male observers, and as an age-specific index in male and female observers.

“…Only participants' left eyes were tracked and calibrated using the standard nine-point fixation EyeLink procedure. For this experiment, a free-viewing paradigm was adopted so as not to constrain spontaneous eye movements, whereby participants were instructed to view the images as "naturally as they normally would" (for similar approaches, see, e.g., Attard-Johnson et al, 2016;Attard & Bindemann, 2013;Fromberger et al, 2012). Each trial began with a fixation dot, which allowed for drift correction.…”
