Towards a Psychologically Plausible Dynamic Binding Mechanism

A psychologically plausible binding mechanism for connectionist networks is sought. Twenty--two subjects were tachistoscopically presented with pairs of coloured shapes which they had to identify almost immediately. The frequencies of their correct responses and various types of incorrect responses were recorded. Simulations of connectionist binding mechanisms were undertaken to discover whether the experimental results can be accounted for by either an enumerated representation model, a non--concatenatively compositional representation model or an oscillatory representation model employing phase synchrony to indicate binding. The effects on these simulations of the different values of their free variables was explored. Whilst none of the simulation results matched the experimental results, the detailed findings suggest improvements to both the experimental method and the design of the simulations. 1.
