Through a cerebral hemispheric specialization model, I speculated that the reported discrepancy between visually impaired children's competency in language development and lags in cognition may be explained by the use of visual-spatial measurements of cognition. The performance of 51 visually impaired and 51 sighted children, ages 7 to 15 years, on a task of joke comprehension and conservation of weight scores was analyzed. I hypothesized that the ability to comprehend verbal humor would reflect the function of the left hemisphere of the brain and the ability to perform a Piagetian visual-spatial task would reflect the function of the right hemisphere. The findings indicate that although age and IQ contributed significantly to predicting joke comprehension, the ability to conserve did not have a unique contribution. In conclusion, I suggest that the cerebral hemispheric specialization model be considered when investigating language and cognition of visually impaired children.
通过大脑半球专门化模型，我推测，视力受损儿童在语言发展能力和认知滞后方面所报告的差异，可能可以通过对认知的视觉空间测量来解释。分析了51名7至15岁视力受损儿童和51名视力正常儿童在笑话理解任务和重量守恒分数上的表现。我假设理解言语幽默的能力将反映大脑左半球的功能，而执行皮亚杰式视觉空间任务的能力将反映右半球的功能。研究结果表明，虽然年龄和智商对预测笑话理解有显著贡献，但守恒能力并没有独特的贡献。总之，我建议在研究视力受损儿童的语言和认知时考虑大脑半球专门化模型。
