Visual Attention and the Semantics of Space

The distinction between central and peripheral cues has played an important role in understanding the functional nature of visual attention for the past 30 years. In the present article, we propose a new taxonomy that is based on linguistic categories of spatial relations. Within this framework, spatial cues are categorized as either “projective” or “deictic.” Using an empirical diagnostic, we demonstrate that the word cues above, below, left, and right express projective spatial relations, whereas arrow cues, eye-gaze cues, and abrupt-onset cues express deictic spatial relations. Thus, the projective-versus-deictic distinction crosscuts the more traditional central-versus-peripheral distinction. The theoretical utility of this new distinction is discussed in the context of recent evidence suggesting that a variety of central cues can elicit reflexive orienting.
