I think the websites might help or might not help.
I tend to see Processing Speed as basically fixed, however there is a lot that can be done to affect the overall length of time that tasks take.

So I'd sit down with DS and ask him what are the things he gets caught up on over and over, and make a list, than rank the top three concerns, and look for something that that you can attack.
Example - perhaps getting out to school in the morning is a problem. The rate of neuron flow might be the same, but having a well oiled set of habits is so much more powerful than that. So brainstorm a list of possible 'habits' that might become automatic and speed up the process. At our house this meant buying more pairs of his favorite style of pants and shirts so that he can set out entire sets of clothing on Sunday for Monday through Friday. I used something like this -

This is the kind of kid who might really want to work at memorizing those times tables in Math, or perhaps he can get accomidation to use a written out table of all Math facts in the classroom so he can continue to learn the content.
I've seen plenty of kids with WM/PRI gaps like this and PS/PRI gaps like this. Having both is a pain in the rear end, but still clearly overcomable. What 'worries' me more is the gap between Verbal and PRI. Clearly anyone with a PRI in the strongly gifted range with 114 Verbal is going to be frustrated in school, where the Verbal skill are worshiped.
It may be that his Verbal type skills are fine and his WM and PSI difficulties blocked him from expressing it to this particular tester on that particular day. Anyway,I'd want to be sure to spend as much time enriching the PRI strength as working on the other challenges.
If you wanna share his top 3 irritations, we can help brainstorm systems and habits.
If you wanna share his PRI related interests, we can help brainstorm possible enrichment activities.
Love and More Love,
