A group of 34 male adolescents with poor results on a spelling test and 34 controls were examined neurologically and neuropsychologically. The index group was inferior to the controls mainly in tasks involving fine motor control of the left hand, but also in auditory non-verbal sequential information processing and phoneme manipulation tasks. The manual sequencing disorder and the verbal and non-verbal auditory problems could be interpreted in terms of deficient information-processing in the left hemisphere, but the reason for the psychomotor disorder of co-ordination, mainly in the left hand, remains unclear.
对一组在拼写测试中成绩较差的34名男性青少年和34名对照组进行了神经学和神经心理学检查。指标组主要在涉及左手精细运动控制的任务中比对照组差，但在听觉非言语序列信息处理和音素操作任务中也较差。手动序列障碍以及言语和非言语听觉问题可以用左半球信息处理不足来解释，但主要是左手的精神运动协调障碍的原因仍不清楚。
