Objects of Our Attention - A/Prof Branka Spehar

What is this research about?

The visual stimulation presents too much information to be perceived, remembered, and acted upon, and only a subset of relevant information is prioritised by attentional processes for further processing. The two most studied aspects of this selective operation concern the manner in which it is achieved (top-down or bottom-up) and the content of such selection (locations or objects).

Perceptual organization – the structuring visual information into coherent units – is of crucial importance and influence in this regard. The aim of this project is to directly probe mechanisms by which isolated and fragmented features are integrated into coherent perceptual wholes capable of influencing attentional deployment.
