Three experiments were conducted to investigate the carry-over of a location-based attentional set from a low-level visual search task to a search of natural images, using eye movements as the dependent measure. In each trial participants searched through letter strings arranged horizontally, vertically, or randomly across the screen, and then searched a natural image. Across all three studies the orientation of the letters influenced the spread of search in the picture task; participants showed wider search in the horizontal axis following a horizontal letter search, and wider search in the vertical axis following a vertical letter search. In Experiment Two this ‘carry-over’ effect also persisted to a second viewing of the natural images. Despite being unrelated to the picture search task, the strategy used to complete the letter search was influencing the way participants searched the pictures. Data from Experiment Three revealed that the strategy used to complete the picture search could also transfer to the letter search. When the task demands in the picture search were manipulated in order to influence fixation duration this had an impact upon fixation duration in the letter search task. The implications of these findings will be discussed.
