To provide coverging support that the proper integration of analog and propositional representational systems is associated with spatial ability, visual, auditory and bimodal brain event-related potentials were recorded from 50 right-handed Caucasian males. Sensory interaction indices were derived for these S s who had taken the Surface Development Test of spatial ability. Product-moment correlations were computed between sensory interaction indices for eight cerebral sites and spatial ability test scores. Sensory interaction for left- and right-hemispheric regions was significantly related to spatial ability. As sensory suppression lessened, spatial ability increased. The results substantiated the theory that the visual-imaginal-analog and the auditory-verbal-propositional representational systems are implicated in spatial ability. The extent to which the cortex can inhibit or attenuate the interaction or integration between these dual-symbol systems is associated with complicated spatial task performance.
