We are often not explicitly aware of the location of our spatial attention, despite its influence on our perception and cognition. During a picture memory task, we asked whether people could later recognise their eye fixations in a two-alternative test. In three separate experiments, participants performed above chance when discriminating their own fixation patterns from random locations or locations fixated in a different image. Recognition was much poorer when the task was to spot your own versus someone else's fixations on the same stimulus, but performance remained better than chance. That we are sensitive to our own scan patterns has implications for perception, memory, and meta-cognition.

How "old" and "attractive" an individual appears has increasingly become an individual concern leading to the utilisation of various cosmetic surgical procedures aimed at enhancing appearance. Using eyetracking, in the present study we aimed to investigate how individuals perceive age and attractiveness of younger and older faces and what "bottom-up" facial cues are used in this process. One hundred and twenty eight digital images of neutral faces of ages ranging from 20 to 89 years were paired and presented to subjects who judged age and attractiveness levels while having their eye movements recorded. There was an effect of face attractiveness on age-rating accuracy, with attractive faces being rated younger than their true age. Similarly, stimulus age affected attractiveness ratings, with younger faces being perceived as more attractive. Judgments of age and attractiveness were tightly linked to fixations on the eye region, along with the nose and mouth. It is thus likely that cosmetic surgical procedures targeted at the eyes, nose, and mouth may be most efficacious at enhancing one's physical appearance.

In science, as in advertising, people often present information on a poster, yet little is known about attention during a poster session. A mobile eye-tracker was used to record participants' gaze during a mock poster session featuring a range of academic psychology posters. Participants spent the most time looking at introductions and conclusions. Larger posters were looked at for longer, as were posters rated more interesting (but not necessarily more aesthetically pleasing). Interestingly, gaze did not correlate with memory for poster details or liking, suggesting that attracting someone towards your poster may not be enough.

Salience-map models have been taken to suggest that the locations of eye fixations are determined by the extent of the low-level discontinuities in an image. While such models have found some support, an increasing emphasis on the task viewers are performing implies that these models must combine with cognitive demands to describe how the eyes are guided efficiently. An experiment is reported in which eye movements to objects in photographs were examined while viewers performed a memory-encoding task or one of two search tasks. The objects depicted in the scenes had known salience ranks according to a popular model. Participants fixated higher-salience objects sooner and more often than lower-salience objects, but only when memorising scenes. This difference shows that salience-map models provide useful predictions even in complex scenes and late in viewing. However, salience had no effects when searching for a target defined by category or exemplar. The results suggest that salience maps are not used to guide the eyes in these tasks, that cognitive override by task demands can be total, and that modelling top-down search is important but may not be easily accomplished within a salience-map framework.
