Here’s how learning disabilities symptoms may also be explained by retained primitive reflexes and incomplete lower brain development.
The criterion for having a learning disability is a considerable difference between intellectual ability and achievement. However, such discrepancy is also the hallmark of a disorganized brain.
Retained primitive reflexes, incomplete development of the lower centers of the brain, and poor vestibular and proprioceptive processing are going to affect a person’s ability to express cognitive thinking, perform motor skills, and learn the content curriculum with ease and success. Such people will have trouble registering, storing, and retrieving information and that, in turn, causes problems with reading, writing, and math.
For example, both brain hemispheres need to work together to solve a math problem: We use our right hemisphere to recognize symbols and numbers and to test the plausibility of an answer. We use our left hemisphere to understand the meaning of symbols, register procedures, carry out sequential tasks, and align numbers in correct columns. So, a retained Asymmetrical Tonic Reflex can interfere with good communication between the hemispheres. As a result, such people often experience difficulty in math.
