Abstract

Three litters from each of 11 inbred strains of rat were tested in a Hebb‐Williams maze. Substantial (p < .001>) genetic and interaction effects were found. Data were analysed in terms of theories of delay of reinforcement, incentive motivation, and adrenergic‐cholinergic balance in task performance. A genetic variable with characteristics reminiscent of Spearman's “g” was found, possibly implicating a single underlying biochemical mechanism. Copyright © 1968 John Wiley & Sons, Inc.
