Better psychomotor performance with VA deficient diet

"In a subsequent study, nine prisoner volunteers were drawn from the same population and, under identical conditions as in the present study, were provided a liquid diet replete in vitamin C and all other nutrients but deficient in vitamin A. Psychological testing during a control period and after 34, 97, and 161 days on the vitamin A-deficient diet indicated no changes for any personality scales of the MMPI and a statistically significant improvement on the performance of several psychomotor tasks, including those showing decrement in the present vitamin C study." (Bold was added by me)
Some behavioral effects of ascorbic acid deficiency

Unfortunately the authors apparently didn't publish that Vitamin A deficiency study, so the above quotation might be all we can find out about it.

So, lets see... they took some people and lowered their VC levels and their psychomotor skills worsened?
Then they took some people and lowered their VA levels and their psychomotor skills increased?
https://www.organizationalpsychologydegrees.com/faq/what-are-psychomotor-skills/
"The psychomotor domain is sometimes referred to as the kinesthetic domain and differs significantly from a purely cognitive learning domain where the psychomotor skill set was first described. Physical activities used to support either cognitive or affective functions are not skill that may be labeled purely psychomotor. To label skills as psychomotor, they must clearly have an educational intention whereby some type of growth can occur with repetition."

One of my children had a hard time with small-motor skills, such as scissors. It was odd enough that teachers mentioned it. I always had crafting stuff out for my kids, so it wasn't because she hadn't used them. She still complains that she is a bit clumsy.
I wonder if clumsy is the word we are looking for here. That dropping VA can help you be less clumsy. Hands... they're not just for decoration. 😉

Definitely less clumsy here. But it started with heavy thiamine supplementation. And went on very nicely with vA avoidance diet. I suppose more thiamine helps get rid of vA.

@lil-chick It is not only a matter of less clumsy, and better psychomotor skills, but also of nimble of thinking. I notice that our mind is more clever, can think things in different ways, it is less stuck into the same limiting routines.
Also when I read the posts of some people, with time on the diet I notice they are getting very bright indeed!

As a kid, I used to be pretty good with my hands. Building stuff, knitting, drawing... all these things I enjoyed. It would be nice to get my old nimble skills back.

During my first attempt with a low VA diet I noticed my handwriting improve in a matter of weeks

Do you have any before and after pictures? That'd be really interesting. My handwriting has been sloppy since around 17. I haven't noticed any improvement there yet.

Grant mentions the same thing in his 5 year update.
"One other very surprising improvement over that last year is the quality of my handwriting. It has become noticeably nicer, more fluid, and stylish"

Yeah, I was aware of his observation. It's intriguing.
