Ralph Burhoe's Evolutionary Theory of Religion

Ralph Wendell Burhoe's legacy rests on a series of interrelated theories that deal with (1) the emergence of life within physical nature; (2) the symbiosis of genes and cultures in human evolution; (3) the central importance of the brain in this symbiosis; and (4) the function of religion within this evolutionary process to carry the traditions of trans-kin altruism that make human civilization possible. These theories give rise to a number of issues that are of current importance. Burhoe's stature is enhanced when one considers that these theories were first articulated by him in the 1970s, in reliance upon the work of J. Bronowski, Alfred E. Emerson, and Donald T. Campbell.     

Two Kinds of Organic Unity

This paper distinguishes two interpretations of G. E. Moore's principle of organic unities, which says that the intrinsic value of a whole need not equal the sum of the intrinsic values its parts would have outside it. A holistic interpretation, which was Moore's own, says that parts retain their values when they enter a whole but that there can be an additional value in the whole as a whole that must be added to them. The conditionality interpretation, which has been defended by Korsgaard, says that parts can change their values when they enter wholes, so no additional value is needed. The paper shows that the two interpretations, which differ on such apparently important issues as the nature of intrinsic value, can always yield the same conclusions about the overall value in a state of affairs, so there is in that sense nothing to choose between them. At the same time, though, the differences between the interpretations make sometimes one and sometimes the other more appropriate for expressing a given evaluative view. In this last connection the paper considers views about beauty, posthumous achievement, vices of disproportion, deserved and compassionate pain, and undeserved and malicious pleasure.     

Correlations of glucose metabolism and structural damage to language function in aphasia

Studies of aphasic patients using [18F]fluorodeoxyglucose positron computed tomographs have shown areas of metabolic depression in the left hemisphere larger than the area of infarction noted on CT. To evaluate these metabolic differences in relationship to language abnormalities, 11 patients had metabolic scans, CT, and were administered the Boston Diagnostic Aphasia Battery and the Porch Index of Communicative Ability. Correlation analyses were computed between metabolic, CT, and language data. CT demonstrated reliable correlations of speaking, oral reading, and repetition to Wernicke' area, consistent with current anatomic language models, while metabolic data from areas posterior, inferior, and superior to the traditional Wernicke's area and the head of the caudate nucleus also had reliable correlations with aphasic language function. The utilization of both structural and metabolic brain measures may improve our understanding of the anatomy of language as related to aphasia.     

Speeded recognition of ungrammaticality: Double violations

A model of sentence comprehension postulating that Subject-Verb-Object relations are specified prior to Noun-Adjective relations received support from a study of the speed at which sentences with various kinds of violations could be rejected. Compatible with the sequential model was the finding that Noun-Verb and Adjective-Noun double violations did not result in shorter RTs than Noun-Verb single violations — even though sentences with double violations were judged to be less acceptable.     

Comparison of the concurrent validity of Holland's theory for men and women in an enterprising occupation

This study examined the concurrent validity of Holland's theory for men and women employed in an enterprising occupation. Using Holland-theme scores obtained from both the Self-Directed Search (SDS) and the Strong-Campbell Interest Inventory (SCII), the degree of personality-environment correspondence and the relationships of personality type to job satisfaction were examined in a sample of 45 male and 43 female sales managers. In general, the findings suggested that, at least within an employed sample, Holland's theory is valid for women as well as for men. Using both the SDS and the SCII, women and men obtained their highest scores on the enterprising theme, and the mean E-theme scores of women were at least as high as were those of men. Significant sex differences on the Realistic, Artistic, and Social scales, found using SDS scores and SCII standard scores, were in the direction of generally-found sex differences. Both men and women were highly satisfied with their jobs, and moderate relationships between job satisfaction and enterprising and social scores were also found. While the results of this study suggest optimism regarding the theoretical and practical utility of Holland's theory for women as well as for men, differences in results as a function of different instruments and scoring methods suggest the need for further studies of this kind.     

A within-subject analysis of stimulus control therapy with severe sleep-onset insomnia.

Stimulus control, a behavioral technique designed to reduce sleep difficulties, has been demonstrated to be effective when compared with control procedures. These comparisons, mainly involving between-subjects analyses, have neglected the contribution of the stimulus control procedure to the production of clinically significant amelioration of sleep dysfunction. In contrast, the present within-subjects experiment was conducted to assess the capability of stimulus control to produce clinically relevant reductions in multiple measures of sleep disturbance. A comparison with the credible placebo procedure indicated that the stimulus control techniques reduced subjects' sleep onset latency to a mean latency below 30 min per week. Additionally, sedative-hypnotic usage was greatly reduced.     

Dissonance motivation: Its nature,persistence, and reinstatement

This paper examines whether arousal is a necessary component of the motivation to reduce dissonance. Alternative responses to attitude-behavior inconsistency include attitude change, explaining the behavior by a consonant cognition (i.e., low choice), and attributing the dissonance-induced state to an alternative source, such as the purported side effects of an ingested “drug.” For conditions in which there are few consonant cognitions (i.e., high choice), a comparison of different “drug” conditions in which attitude change does or does not occur was expected to clarify which components of the dissonance-induced state mediate attitude change. Attitude change occurred in high choice conditions where the “drug” was described as pleasant, but not in high choice conditions where the “drug” was described as unpleasant or in a low choice condition. In addition, when the “drug” was descibed as arousing there was, if anything, more attitude change than when the “drug” was described as nonarousing. These results suggest that unpleasantness and not arousal per se is the motivating factor in dissonance reduction. The effects of the passage of time and reinstating the counterattitudinal behavior on the alternative responses to attitude-behavior inconsistency were also examined. Subjects returned 2 weeks later, stated their attitudes, recalled their original counterattitudinal essay, and again stated their attitudes. Although there was a general decrease in attitude change during this period, the pattern of attitude change remained basically the same. Attitude change following reinstatement increased from its original level only in those conditions where it had been initially attenuated through misattribution or a consonant cognition.     

Consistency of the labial temperature change measure of human female eroticism

Six adult, human female volunteers participated in a study to determine the consistency of their pattern of sexual arousal to two erotic films over two experimental sessions. Sexual arousal was assessed objectively by means of continuous measurement of temperature changes of the labia minora and subjectively by periodic self-ratings. Each subject developed increases in labial temperature to both film presentations that ranged from about 0.10°C to 1.36°C above basal levels. The amount of temperature change in a subject's labia minora during the first film presentation was significantly correlated with that during the second film, and there was a reasonable degree of consistency across the two sessions with regard to the rate at which the subject's labial temperature subsided towards basal levels after the cessation of erotic stimulation. Labial temperature changes and subjective ratings were also significantly correlated during each of the two film presentations.
