Androgen Deprivation Alters Attention to Sexually Provocative Visual Stimuli in Elderly Men.

Introduction: Testosterone is known to regulate male sexual interest, but the exact way that androgens influence men's sexual cognition remains unclear.

Aim: To investigate the influence of androgen deprivation (AD) on visual responses to sexually suggestive stimuli in men treated for prostate cancer with AD therapy.

Methods: Patients with AD-treated prostate cancer, patients with prostate cancer not on AD therapy, and age-matched healthy control participants were exposed to images of male and female runway models fully or minimally clothed.

Eye contact affects attention more than arousal as revealed by prospective time estimation.

Eye contact can both increase arousal and engage attention. Because these two changes impact time estimation differently, we were able to use a prospective time estimation task to assess the relative changes in arousal and attention during eye contact. Pairs of participants made a 1-minute prospective time estimate while sitting side-by-side and performing three different gaze trials: looking at the wall away from their partner (baseline/away trials), looking at their partner's profile (profile trials), or making eye contact with their partner (eye contact trials).

Wearable computing: Will it make people prosocial?

We recently reported that people who wear an eye tracker modify their natural looking behaviour in a prosocial manner. This change in looking behaviour represents a potential concern for researchers who wish to use eye trackers to understand the functioning of human attention. On the other hand, it may offer a real boon to manufacturers and consumers of wearable computing (e.

Hide and seek: the theory of mind of visual concealment and search.

Researchers have investigated visual search behavior for almost a century. During that time, few studies have examined the cognitive processes involved in hiding items rather than finding them. To investigate this, we developed a paradigm that allowed participants to indicate where they would hide (or find) an item that was to be found (or hidden) by a friend or a foe.

Top-down and bottom-up aspects of active search in a real-world environment.

Visual search has been studied intensively in the labouratory, but lab search often differs from search in the real world in many respects. Here, we used a mobile eye tracker to record the gaze of participants engaged in a realistic, active search task. Participants were asked to walk into a mailroom and locate a target mailbox among many similar mailboxes.

Leftward biases in picture scanning and line bisection: a gaze-contingent window study.

A bias for humans to attend to the left side of space has been reported in a variety of experiments. While patients with hemispatial neglect mistakenly bisect horizontal lines to the right of centre, neurologically healthy individuals show a mean leftward error. Here, two experiments demonstrated a robust tendency for participants to saccade to the left when viewing photographs.
