Modeling eye movements in visual agnosia with a saliency map approach: Bottom-up guidance or top-down strategy?
2011, Neural NetworksCitation Excerpt :The structure of the saliency map model, and it’s inspiration in the hierarchical organization of the visual field, raises an interesting additional possibility: if some agnosias arise from a selective impairment in a particular type of feature, then their attentional behaviour might be better accounted for by adjusting the weights of the different features in the model. Simulating the disruption of different cognitive abilities by “lesioning” connectionist models has proven a useful tool in neuropsychology and artificial intelligence (see Olson & Humphreys, 1997, for a review), and here we sought similar insights by selectively tuning the saliency model based on observed behavioural deficits. As a proof of principle, we reanalyzed CH’s fixations on scenes during the view-and-remember task, varying the contribution of the three different feature channels that went into calculating visual saliency.
