Compilers of crosswords take heart from their understanding of human nature. It is easier to reach for a pencil and attempt a crossword in the morning than go to the local gym. Crossword addicts maintain, however, that they are exposing their brains to a mind gym.
I suppose the `best’ pleasure obtained from completing a cross word is in satisfaction in over coming a challenge. The will probably always be one or two clues that hold you up - but the fierce enjoyment of completing the crossword more than makes up for the frustration of not being able to give the solution immediately.
Verbal reasoning exercises also call for the ability to solve word problems. I can not see however the satisfaction of completing a number of verbal reasoning questions can compete with the joy of filling in the final letters so that you just know that you have completed the grid.
In a crossword every clue has to have some form of a definition. This means that the answer has to be unique. We have all worked through verbal reasoning exercises where occasionally there have been more than one answer. This gives real pleasure to all concerned - particularly when the answer book has a range of answers.
Once the verbal reasoning tests are over, turning to crosswords may give pleasure and stimulation to young minds for many years to come. The great benefit of a crossword is that it can be cast aside - and then picked up when the mood strikes. We are not quite sure why the brain is sometimes able to solve a problem if there has been a delay or period of incubation.
So when you are working on a verbal reasoning paper, and the answer is not immediately apparent, be reasonably confident that you may be able to solve the problem a little later on.
