Any thought ? Yes, I have thoughts but they often disappear into the vapors unless I am able to write them down. But, that is just my messed up brain.

All kidding aside,

Speed of processing has been found to be important in many endeavors. The training studied also includes peripheral vision exercises. Researchers used to believe speed of processing was the basis for higher levels of intelligence. Recently, they have discovered that the ability to observe and include peripheral information in cognitive processes is the primary basis for increased intelligence levels.

One issue they do not address is quite simple. Did these subjects studied develop 'lazy' brains as they aged or were they living a lifestyle of low key mental effort or focus or was there any other way of quantifying their pre-existing processing speed ?

Many brain training exercises cause improvement in the specific task of the exercise. Did these improvements start from a mean level, below mean or above mean ? Is the mean level due to cultural and experiential standards ? Modern society tends to be narrowly focused in most activities. TV's, smart phones, a single teacher/lecturer, narrow educational focuses, teaching to the test, etc. tend to limit the needs to develop peripheral vision and processing skills. In generations past, there was more need to see and process a broader field of view, both visually and educationally.

So, does brain training just develop skills that have lied dormant and under developed because they have not been used and exercised ?

It makes one wonder how much an injured brain can accomplish by exercising and developing many of these underdeveloped skills.

I think I am going to dig out my Posit Science brain training suite and see if it included the speed of processing training or UFOV exercises used.
