Understanding object feature binding through experimentation as a precursor to modelling

In order to explore underlying brain mechanisms and to further understand how and where object feature binding occurs, psychophysical data are analysed and will be modelled using an attractor network. This paper describes psychophysical work and an outline of the proposed model. A rapid serial visual processing paradigm with a post-cue response task was used in three experimental conditions: spatial, temporal and spatio-temporal. Using a ?staircase? procedure, stimulus onset asynchrony for each observer for each condition was set in practice trails to achieve textbackslashtexttttextbackslashchar12650cue. In future work, the model could be lesioned so that neuropsychological phenomena might be exhibited. In such a way, the mechanisms underlying object feature binding might be clarified.
