Abstract
Motivation, affect and cognition are interrelated. However, the control of attentional deployment and more specifically, attempting to provide a more complete account of the interactions between the dorsal and ventral processing streams is still a challenge. The interaction between overt and covert attention is particularly important for models concerned with visual search. Further modeling of such interactions can assist to scrutinize many mechanisms, such as saccadic suppression, dynamic remapping of the saliency map and inhibition of return, covert pre-selection of targets for overt saccades and online understanding of complex visual scenes.
Highlights
The interplay between bottom-up and top-down influences on overt attention is the key for investigating and modeling attention
The functionality of this model lies on the presence of a saliency map, analyzing an image through distinct characteristic maps and other specific operands as well as a winner-take-all neural network selecting the area of the image towards which attention is oriented
Attention is the basis of human cognition and can be trained in favor of mental flexibility, learning and self-consciousness
Summary
The interplay between bottom-up and top-down influences on overt attention is the key for investigating and modeling attention. Future research should begin with widening the currently narrow scope on top-down factors. Attentional and emotional processes are in the focus of research, overall research in this field is just at the beginning and suffers from the diversity of concepts of both attention and emotion. Models of saliency maps and research on elementary image features have not considered emotional components. It is a challenging task for future research to incorporate bottom-up factors and emotion as a strong top-down factor
