Selective spatial enhancement: Attentional spotlight size impacts spatial but not temporal perception

Goodhew, Stephanie Catherine; Shen, Elizabeth; Edwards, Mark


An important but often neglected aspect of attention is how changes in the attentional spotlight size impact perception. The zoom-lens model predicts that a small ("focal") attentional spotlight enhances all aspects of perception relative to a larger ("diffuse" spotlight). However, based on the physiological properties of the two major classes of visual cells (magnocellular and parvocellular neurons) we predicted trade-offs in spatial and temporal acuity as a function of spotlight size....[Show more]
