Are processing problems inherited or caused by environmental factors?
There is evidence that processing deficiencies in skills such as processing speed and auditory analysis run in families. Slow mindedness, for example, often is found in families. This makes the problem an inherited problem. There is also evidence that processing development is delayed by physical trauma such as disease, like spinal meningitis and cancer, that captures the brain at critical times when processing skills should be developing. There is also evidence that emotional trauma is a cause. Sometimes the cause can be related to early life deprivation. Learning Solutions has tested several children, who spent their first formative years in orphanages from Romania, Bulgaria, or Russia, and all have had very weak processing skills. Whether the cause is physical or emotional (environmental trauma) does not matter. The important thing to know is that the undeveloped brain can be developed by proper mental exercises, with enough intensity, and patient repetitions.
