Fig. 2From: Strengthening spatial reasoning: elucidating the attentional and neural mechanisms associated with mental rotation skill developmentBefore training, the training groups did not differ in accuracy on the cubes task (a) or the molecules task (b). After training, both training conditions improved on the cubes task (a), but the experimental group improved significantly more than the control group. Only the experimental group improved on the molecules task (b)Back to article page
