Electrophysiological correlates of adult decisions made during a conservation of quantity task.
Visual evoked responses were recorded from 10 scalp locations over the left and right hemisphere while adults were involved in a conservation of quantity task. Multivariate analyses involving principal components analysis and ANOVA identified bilateral and left hemisphere lateralized components of the visual evoked responses which discriminated between conservation judgments made by subjects.
