The author nails the biggest issue with the cognitive approach right on the head with his final statement. Comparing the workings of the human mind to the way that a computer functions is unfortunately a very bad oversimplification of the process thoughts and emotion go through.
I do think that someday we will be able to decode the brain as MrPolitic99 mentions. Beyond decoding the electrical code I also think that advancements in other areas of science including the understanding of different wavelengths coming from the human mind will open up the possibilities of us actually dissecting the though process.
Yes, as crazy as it sounds I do think that what we now call extra sensory perception, or ESP, will someday be explainable. We may not learn how to communicate telepathically but I do think that we can develop technology that will further understand the thoughts emitting from the human mind.
Right now we can use magnetic resonance imaging to see the activity in different parts of the brain but we have still a very primitive way of decoding the activity.
I have hope that no matter what the correct or more proper way of analyzing the brain comes to be that we will be capable of further helping those with psychological and mental disorders.
