Hi TeeEss and welcome here,
I just wrote to another new member about NLD, where I mentioned using a graphical organizer, which is also called 'mind-mapping'.
Where this is really to do with your note that: 'he can get anxious when things don't go to plan'?
Where with NLD, people use Verbal rather then Non-Verbal planning?
Non-Verbal planning is more like a visual plan. Where we can see the plan as a whole, which makes it much easier change and rearrange parts within it.
But with Verbal planning, we have a series of words that outline the plan.
Where if you look at this Verbal plan as a paragraph that you have just written?
Where a change occurs, so that you have to remove one sentence in the paragraph?
Which will probably mean that you have to start all over again?
Though a graphical or mind mapping approach to planning?
Instead of creating a list, it organizes things around a whole page. So that we can look and see how it all fits together.
So that when any part changes? We don't have to start all over again? As we can see how that part fits into the whole plan.
Though he could also use it to prepare for any possible changes?
As an analogy, you might compare a verbal plan that describes how to arrange everything in a room?
As opposed to a picture as a plan?
But then we have a change to the plan?
With the picture, it would be easy to see what effect the change would have.
But with the verbal plan, we might have to start all over again?
So that what I'm rather suggesting, is that it could provide an opportunity for him to explore a different way of planning, that can cope with changes?
