Bridging psychology and biology with animal research.

Comments on the article by S. M. Kosslyn et al (see record 2002-12932-001), which advocated combining group-based research and individual differences research to illuminate the links between psychology and biology. The authors agree that the study of individual differences is vital for uncovering processes that have hitherto remained obscured by relying too heavily on group-level approaches, and commend their multilevel, multidisciplinary approach to this important topic. However, they believe that Kosslyn et al should have given more attention to one of the most promising avenues for pursuing their multilevel approach--comparative research. The authors suggest that, although Kosslyn et al did refer to animal studies, they did not sufficiently emphasize the potential contribution of animal research.
