Research Interests

I am interested working memory capacity and the relationship of that concept to the concept of attention control. I have argued that individual differences in the construct measured as working memory capacity reflects differences in the ability to control attention to internally generated and externally elicited representations and that differences in this ability is an important component of general fluid intelligence (Engle & Kane, 2004). I have also entertained the likelihood that these differences reflect functioning of the normal frontal lobes which in turn reflect genetic differences in the regulation of dopamine and possibly other neurotransmitters.
