What is it about?
In this work we have studied the role of verbal working memory capacity in a non-verbal task – mental image rotation. If this capacity were domain specific it would be expected that high and low verbal span participants would obtain similar results in the mental rotation task. We have found that this is not the case as the high span participants performed better in terms of both speed and accuracy. Moreover, these differences depended on the processing component of the mental rotation task: the higher the processing requirements the higher the differences as a function of the working memory capacity. Therefore, the evidence presented here supports the domain general hypothesis.
