Abstract

Discusses 3 issues raised by M. W. Eysenck and S. Folkard (see record 1981-07363-001) in their discussion of findings by the present authors (see record 1981-07372-001). The issues include (a) the individual difference variable mediating the time of day and caffeine effects; (b) the difference between the diurnal rhythms of low and high impulsives; and (c) the necessity of postulating multiple activation states.
