The cognitive processing of symbolic and nonsymbolic events was compared. Evidence was drawn from the clinical and experimental literature on normal processing, on hemispheric asymmetry and on brain damage sequelae. It was concluded that several basic cognitive activities were manifest both symbolically and nonsymbolically. The cognitive activities included analysis of rapidly changing stimuli, categorical perception, categorical production, hierarchical organization and the production of complex movements. Damage to subcortical as well as cortical structures may contribute to the covariation of symbolic and nonsymbolic deficits. Suggestions were made for future research and the implications for the understanding of aphasia were described.
对符号性和非符号性事件的认知加工进行了比较。证据取自关于正常加工、半球不对称性和脑损伤后遗症的临床及实验文献。得出的结论是，几种基本的认知活动在符号性和非符号性方面均有体现。这些认知活动包括对快速变化刺激的分析、范畴知觉、范畴生成、层级组织以及复杂动作的产生。皮层下结构和皮层结构的损伤可能导致符号性和非符号性缺陷的共同变化。针对未来研究提出了建议，并描述了其对失语症理解的影响。
