ALTRUISM AND THE ADMINISTRATION OF THE UNIVERSE: KIRTLEY FLETCHER MATHER ON SCIENCE AND VALUES

Abstract. Few American scientists have devoted as much attention to religion and science as Harvard geologist Kirtley Fletcher Mather (1888–1978). Responding to antievolutionism during the 1920s, he taught Sunday School classes, assisted in defending John Scopes, and wrote Science in Search of God (1928). Over the next 40 years, Mather explored the place of humanity in the universe and the presence of values in light of what he often called “the administration of the universe,” a term and concept he borrowed from his former teacher, geologist Thomas Chrowder Chamberlin. Human values, including cooperation and altruism, had emerged in such a context: “the administrative directive toward orderly organization of increasingly complex systems transcends the urge for survival.” He was also active in the early years of the Institute on Religion in an Age of Science, an organization created by his good friends Ralph Wendell Burhoe and Harlow Shapley.     

A Vocational interest test minus sex bias

The Vocational Preference Inventory responses from 290 subjects (110 males and 180 females) were subjected to a Rasch item analysis, one of a class of latent trait models. After elimination of 22 items which did not fit the model, a sex-free form of the VPI was obtained. Group interest scale scores are presented for each of the Holland scales and data are produced which indicate that no violence was done to the Holland coding system.     

The center and range of the probability interval as factors affecting ambiguity preferences

Ambiguous decision situations are characterized as having probabilities that are uncertain. The uncertainty is due to the common, real-world deficiency of information about the process by which the outcomes are determined. Thirty lotteries having uncertain probabilities were constructed by varying the centers and the ranges of the intervals within which the imprecise probabilities of winning could lie. Pairs of the lotteries were presented as choice alternatives to subjects, with each pair having lotteries with the same interval center but differing interval ranges. Ambiguity avoidance, the selection of the less ambiguous option, was found to increase with the interval center C, with ambiguity indifference occurring for values of C ? 0.40. No evidence of ambiguity seeking as the prevalent behavior was obtained. Ambiguity avoidance did not significantly increase with the interval range R, but an interaction effect between C and the ranges R₁ and R₂ of the choice pair was obtained. This effect of the ranges could not be described simply by knowledge of the difference R₁ ? R₂; knowledge of both individual values was necessary. The theoretical implications of these results are discussed.     

Enhancing children's attitudes toward disabled peers using a multi-media intervention

Interventions are being developed to enhance children's attitudes toward disabled peers and thereby facilitate mainstreaming in schools. This study evaluates the impact of Feeling Free, a multi-media program of disability-related films, activities, discussions, and books. Participants were children from 16 classrooms, grades 3 through 6. Two classes at each grade level (N = 8) were randomly assigned to the six-session program and were compared on five outcome measures to the eight remaining classrooms. Treatment children demonstrated increased knowledge about disabilities, more positive perceptions of disabled persons, and greater awareness of appropriate behavioral responses to disabled peers. There were no long-lasting treatment effects on two measures of children's acknowledged willingness to interact with disabled peers, although treatment girls demonstrated short-term gains on one measure. Suggestions are made for increasing program impact and providing services to other participants in the mainstreaming process.     

Rule learning in children: Multiple-set training and intermediate-size transposition

Two experiments were conducted in which the subjects were trained to choose the middle-size stimulus in either a single stimulus set or in each of two nonoverlapping stimulus sets. Following criterion, each subject was presented with a series of 12 test trials involving a new stimulus set. In Experiment 1, kindergarten children tended to choose the middle-size test stimulus if the test set consisted of stimuli intermediate in size to the stimuli in the smaller and larger training sets. When the test stimuli were all larger than any of the training stimuli, the probability of choosing the middle-size stimulus increased as the distance between the two training sets increased. Three groups of children participated in Experiment 2: a kindergarten group, a first-grade group, and a first-grade group that experienced middle-size training a year earlier. The distance between training sets and two training procedures affected the three groups in a similar manner during acquisition, but several interactions were obtained during the test. The findings were discussed in terms of the Lane and Rabinowitz (D. M. Lane & F. M. Rabinowitz, Child Development, 1977, 48, 412–426) rule based theory of intermediate-size transposition and suggestions were made as to how children acquire the concept of middle.     

Visual discrimination learning with a 1-min delay of reward

Eight rats were successfully trained in a black-white discrimination with a 1-min delay of reward. The procedure was unusual in that the rat spent the delay outside the apparatus in its home cage. Immediately after the rat responded, whether correctly or incorrectly, it was removed from the choice compartment and placed in its home cage. When the delay ended, it was returned to the startbox. If the preceding response had been correct, the rat received a reward of sugar water; otherwise, it was allowed to make another choice response. Mediation by external cues was excluded because there was no difference in the way the rats were treated after a correct or an incorrect response until the delay interval ended. Mediation by proprioceptive stimuli was excluded because position was an irrelevant cue.
