Learned helplessness in the rat.

Four experiments attempted to produce behavior in the rat parallel to the behavior characteristic of learned helplessness in the dog. When rats received escapable, inescapable, or no shock and were later tested in jump-up escape, both inescapable and no-shock controls failed to escape. When bar pressing, rather than jumping up, was used as the tested escape response, fixed ratio (FR) 3 was interfered with by inescapable shock, but not lesser ratios. With FR-3, the no-shock control escaped well. Interference with escape was shown to be a function of the inescapability of shock and not shock per se: Rats that were "put through" and learned a prior jump-up escape did not become passive, but their yoked, inescapable partners did. Rats, as well as dogs, fail to escape shock as a function of prior inescapability, exhibiting learned helplessness.     

Prepared phobias and obsessions: Therapeutic outcome

Sixty-nine phobic and eighty-two obsessional patients, treated at the Maudsley Hospital, were rated for ‘preparedness’, the evolutionary significance of the content and behaviour of the disorder. Reliable ratings (r = 0.78 and 0.90) of the dangerousness of the object or situation to pretechnological man indicated that the content of the large majority of the phobias and obsessions are judged as evolutionarily significant. Degree of preparedness, however, did not predict outcome of therapy, suddenness of onset of the disorder, severity of impairment, intensiveness of the treatment received, or age of onset. Nor was there any significant relationship between preparedness and certain other variables in the obsessional sample: stimulus generalization, effect on life style, impaired reproductive capacity and abnormal personality. The implications of these findings for the hypothesis that human phobias and obsessions are prepared, and for the clinical usefulness of the concept of preparedness, are discussed.     

Predicting Summer Energy Consumption from Homeowners' Attitudes1

Two surveys were conducted to examine the relationship between homeowners' attitudes toward energy use and their actual summer electric consumption. In Survey 1, 56 couples filled out questionnaires concerning their energy attitudes. A factor analysis of their responses revealed four factors: comfort and health concerns, effort to conserve and monetary savings, role of the individual, and legitimacy of the energy crisis. The factors were entered into a multiple regression analysis to predict actual summer electric consumption. The attitudinal factors together significantly accounted for 55% of the variance in summer electric consumption. The comfort and health factor by itself explained 30% of the consumption variance. Survey 2, consisting of 69 couples, was conducted to elaborate the meaning of the factors. The results of the factor analysis of Survey 2 revealed six factors: comfort, health, individual's role, belief in science, legitimacy of the energy crisis, and effort to conserve. An overall regression analysis showed that the factors significantly explained nearly 60% of the summer consumption variance. The comfort factor was again the best predictor of summer electric consumption, accounting for 42% of the variance. It was concluded that attitudes about one's comfort are significantly related to household energy consumption (primarily air conditioning). The implications for energy conservation campaigns were discussed.     

Champ or chump: strategic utilization of dual social identities of others

The Jamaican‐born, Canadian sprinter, Ben Johnson, won the gold medal at the 1988 Olympics, but afterward was disqualified for steroid use. At the time Johnson's identity in the Canadian media appeared to shift—he was ‘Canadian’ after winning the gold medal but ‘Jamaican’ after disqualification. We tested this hypothesis via an archival study of a newspaper database of Canadian newspapers. The results confirmed the speculation. In the second study with Canadian research participants, the nationality of a fictional athlete was experimentally manipulated. He either possessed Canadian‐ American (shared) or Belgian‐American (non‐shared) identity. The athlete's performance outcome at an Olympic event was also manipulated. In the shared identity condition the athlete was perceived as more Canadian when he won than when he lost. There were no significant differences in nationality judgment when neither of the athlete's dual nationalities was Canadian. Results regarding perceptions of similarity paralleled the nationality‐ratings results. Findings from these two studies illustrate an interesting extension of BIRGing and CORFing strategies in which multiple social identities of others are used strategically to include or exclude others from the in‐group.

Unpacking Intuition: A Conjecture

ABSTRACT— Can intuition be taught? The way in which faces are recognized, the structure of natural classes, and the architecture of intuition may all be instances of the same process. The conjecture that intuition is a species of recognition memory implies that human intuitive decision making can be enormously enhanced by virtual simulation.
