Abstract
Abstract – Most who have spent any time working on visual attention intuitively know that saliency, selection, and eye movements are somehow connected, but details on their linkages seem elusive. These connections are important to the evolution of our new cognitive architecture STAR (Selective Tuning Attentive Reference). This presentation will begin with very brief overviews of STAR, of our Selective Tuning model of visual attention (ST) and of our visual saliency model AIM (Attention via Information Maximization). It will then develop how ST and AIM interact and what their roles might be in the decisions to move eye gaze within STAR. The result, the STAR-FC model (STAR – Fixation Controller) will be described and its performance detailed. Although a fully implemented computational model, it is unique in that not only does it exhibit human-like performance but it also provides a wealth of falsifiable predictions for future experimental investigation.
