The idea that reading ability might vary with right-left hand skill, such that children with mild biases to the right hand have advantages for learning, while children at both left and right extremes have disadvantages, was supported by findings for a large sample of primary schoolchildren. Poor readers tended to have weak left hand skills, giving strong right hand preferences in many cases. Those with additionally poor right hand skills tended to be of low intelligence. Good left hand skills and raised incidences of mixed and left hand preference were found only in a small subgroup, "bright dyslexics".
阅读能力可能因左右手技能而异的观点，即右手有轻微偏向的儿童在学习上具有优势，而左右手极端偏好的儿童则处于劣势，这一观点得到了大量小学生样本研究结果的支持。阅读能力差的儿童往往左手技能较弱，在许多情况下表现出强烈的右手偏好。那些右手技能也很差的儿童往往智力较低。只有在一个小的亚组“聪明的诵读困难者”中发现了良好的左手技能以及混合手和左手偏好发生率的增加。
