Because the non-adaptive arithmetic task was a completely different
kind of activity from the creativity assessment, so different that the
training did not have any negative transfer (interference) to the
creativity assessment.
I am under the impression that context and task similarity contribute
independently to the degree of interference that training at one task
will have on another, and it seems likely that the creativity
assessment and adaptive arithmetic task both require cognitive
control. (one component of the creativity assesment - thinking of the
number of uses of an object, is also used to evaluate frontal lobe
function) But, prolonged training at a non-adaptive arithmetic task
eventually causes the trainee to switch strategies from mental
calculation to recollection. So, the non-adaptive arithmetic task
probably did not demand much cognitive control for the trained
subjects. This means the task similarity is much higher between the
creativity assessment and the adaptive arithmetic task than it is
between the creativity assessment and the non-adaptive arithmetic
task.
