Dissociation between normal hemispheres in delayed recognition of verbal and spatial cues of the same visual pattern

Is each hemisphere capable of disentangling a specific kind of information from a complex 3-target set of stimuli in an expectancy-free delayed recognition experiment on normals? A tachistoscopical study set out to answer this question. It provided evidence for a double dissociation between the hemisphere of input of complex stimuli (comprising both spatial and verbal information) and the kind of information to be retrieved.
