Although many human behaviors are held to have adaptive significance, specific examples of behaviors that represent direct holdovers from the ancient world have been few, particularly in the cognitive realm. In the present research, the authors tested the hypothesis that such cognitive examples might in fact exist and be experimentally verifiable. They suggested that human predispositions to learn basic aspects of hunting with relative ease might be "left over" from human evolution in the pre-agricultural past. This hypothesis was tested in 3 experiments with reference to the learning and recall of animal tracks, an activity of probable high adaptive significance within the area of visual memory. Undergraduate students selected at random learned and recalled animal tracks with significantly greater ease than they recalled other animate and inanimate items. A single exception lay in relatively unfamiliar kitchen implements, which were recalled with greater facility than were animal tracks, consistent with current theoretical considerations. Results indicate that direct behavioral holdovers from the ancient world may exist in the cognitive realm and that these may be accessed experimentally and predictably under appropriate conditions.

Although previous research has shown the importance of feature-intensive processing of relevant information in the staving off of addictive behaviors, the present study examined the possibility that a more global, gestalt rejection of cigarette smoking may be operating to reduce smoking behavior. The present study addressed this possibility through the use of a decision efficacy rating procedure, in which smoking and nonsmoking respondents were asked to determine whether an individual was justified in smoking in a variety of given situations. Nonsmokers tended to reject smoking under any circumstances, whereas smokers tended to entertain mitigating circumstances more favorably in justifying smoking, especially when smoking could be construed as providing some perceived positive gains in serious situations. Results are discussed in terms of the gestalt/feature-intensive processing theory of cognition, and in terms of the importance of cognitive approaches to the understanding of addictive behaviors.
