THE CEREBRAL HEMISPHERES AND NEURAL-NETWORK SIMULATIONS - DESIGN CONSIDERATIONS

The conclusions concerning hemispheric specializations based on neural network simulations, which were previously reported by Kosslyn, Chabr is, Marsolek, and Koenig (1992), are shown not to be valid. Difference s in network performance on tasks said to be ''categorical'' and ''coo rdinate spatial'' in nature were due to imbalances in the input stimul i and cannot, in principle, be related to differences in performance o n such tasks in human subjects. The use of truth tables and correlatio n coefficients in the design of neural networks is discussed.
