Abstract

A study of spatial attention is reported in which different colours and categories of object tended to appear at different locations. Subjects made speeded orientation judgements to alphanumeric characters that could appear either above or below the centre of a display. In the Colour Condition subjects were informed that red characters tended to appear at one location (p = 0.8), while green characters tended to appear at the other. In the Category Condition letters tended to appear at one location, and digits at the other. Before each trial subjects were cued to expect either a red or a green character (Colour Condition); or a letter or a digit (Category Condition). It was found that spatial selectivity varied according to the colour, or category of object presented. The latter finding replicated an earlier report (Lambert 1987). Spatial selectivity was appropriate for the character presented, even when it was in the uncued colour (or category). It is concluded that subjects are able to form and make use of complex attentional expectancies concerning combinations of colour with location, and category with location. Theoretical implications of these results are discussed.
