Fig 1. Overview of experimental task.

One of the four possible cues appeared on the screen followed by a fixation cross for a random interval. Colour scheme was random and irrelevant for the current task. Participants were asked to press the button as quickly as possible once the landscape picture (one of a random set of ten), was presented on the screen. This was followed by a feedback display as to whether or not they were successful in the task and their current point total.
