RELIGION AND THE THEORIES OF SCIENCE: A RESPONSE TO BARBOUR

Abstract. This paper offers a detailed response to “Religion and the Theories of Science” in Barbour's Gifford Lectures I. Topics include: complementarity, indeterminacy, parts and wholes, and Bell's theorem in quantum theory; metaphysical issues raised by relativity theory and thermodynamics, principally the problem of temporality and “top-down” versus “bottom—up” causality; design arguments and the origins of the universe in astronomy and creation; and God's action in the context of evolution and continuing creation. Areas of agreement and disagreement between Barbour and myself over philosophical and theological implications are presented, and endnotes indicate further areas of conversation.     

A Systematic Framework for Integrating Psychological Evaluations and Interventions

A systematic framework for an integrative approach to psychological evaluations and interventions is proposed based on the executive system model of intelligence, the transactional processes of stress and coping, and the field properties of the personal domain. The executive system of intelligence is a comprehensive model that helps to explain the active components of various types of psychotherapies. We are proposing that psychotherapies facilitate clients' uses of their executive functions to develop coping strategies in their transactions with the environment and the events in their life space. A clinical case is presented to illustrate our systematic approach to psychological evaluation and intervention.     

Caregivers of adults with cancer: Multidimensional correlates of psychological distress

The relationship between psychological distress and intrapersonal, family, and socioecological variables was examined in 77 caregivers of adults actively receiving cancer treatment. Results indicated that a sizable minority (29%) of caregivers was experiencing clinically significant psychological distress. Furthermore, family disturbances and maladaptive coping strategies were most predictive of psychological distress in this sample. The clinical implications of these findings in relation to the assessment and treatment of both patients and caregivers are discussed.     

Preferred rates of repetitive tapping and categorical time production

In a constrained finger-tapping task, in which a subject attempts to match the rate of tapping responses to the rate of a pacer stimulus, interresponse interval (IRI) was a nonlinear function of interstimulus interval (ISI), in agreement with the results of Collyer, Broadbent, and Church (1992). In an unconstrained task, the subjects were not given an ISI to match, but were instructed to tap at their preferred rate, one that seemed not too fast or too slow for comfortable production. The distribution of preferred IRIs was bimodal rather than unimodal, with modes at 272 and 450 msec. Preferred IRIs also tended to become shorter over successive sessions. Time intervals that were preferred in the unconstrained task tended to be intervals that were overproduced (IRI > ISI) when they were used as ISIs in the constrained task. A multiple-oscillator model of timing developed by Church and Broadbent (1990) was used to simulate the two tasks. The nonlinearity in constrained tapping, termed theoscillator signature, and the bimodal distribution in unconstrained tapping were both exhibited by the model. The nature of the experimental results and the success of the simulation in capturing them both provide further support for a multiple-oscillator view of timing.     

The effects of methylphenidate on various types of activity level and attention in hyperkinetic children

The effects of methylphenidate on a number of objective measures of activity level and attention were assessed on three repeated occasions in four types of settings: free play, movie viewing, testing, and restricted play periods. Subjects were 36 boys between 5 and 12 years of age and of average intelligence. Of these, 18 were diagnosed as hyperkinetic and participated in a double-blind drug-placebo crossover design. The remaining 18 boys, matched in age and IQ with the hyperkinetic children, served as a control group and received no drugs. Results indicated that compared to placebo, methylphenidate significantly reduced wrist, ankle, locomotor, and seat movement activity in the hyperkinetic children regardless of the type of setting in which the measures were taken. Relatively fewer significant drug effects were noted on the measures of concentration or attention. While concentration to reaction time, maze performance, and a movie viewing task improved during drug treatment, the length of attention to toys in free play was not significantly improved. Parental ratings of activity level were also improved by the drug. The hyperkinetic children were also observed to increase their level of task-irrelevant activity over time while control children remained relatively stable in activity over repeated assessment. Despite the positive drug effects, clinical observations suggested that methyl-phenidate may have reduced the interest of some children in their environment.     

On the consistency between attitudes and behavior: Look to the method of attitude formation

A field study and a laboratory experiment were conducted to test the hypothesis that the method by which an attitude was formed is a crucial variable affecting attitude-behavior consistency. It was predicted that people who form their attitudes on the basis of direct behavioral interaction with the attitude object will demonstrate significantly greater attitude-behavior consistency than individuals whose attitudes were formed by other means. In the field study, students with direct prior experience with a housing crisis demonstrated greater consistency between their attitudes and behavioral attempts to alleviate the crisis than did students with similar attitudes but without prior direct experience. In the laboratory experiment, subjects who indicated their attitude toward a variety of puzzle types after working examples of each demonstrated greater consistency between these attitudes and subsequent behavior in a free play situation than subjects with similar attitudes formed on the basis of information given by the experimenter. It was suggested that direct behavioral experience produces an attitude which is more clearly, confidently, and stably maintained than an attitude formed through more indirect means.     

Good News-Bad News: Affective and Interpersonal Effects1

News broadcasts conveying “good news” or “bad news” were played to subjects who subsequently made evaluative responses of anonymous others. The news broadcasts were shown to differentially elicit positive and negative affective responses and to affect subjects' evaluations of others. Additionally, reported affect was shown to be positively related to those interpersonal evaluations.     

On the Piliavin & Piliavin Model of Helping Behavior: Costs Are in the Eye of the Beholder

Two field experiments tested the Piliavin and Piliavin cost-reward model of helping. The model predicts that the most helping should occur when the costs for helping are low and when the costs for not helping are high. The results of Experiment 1 provided partial support for this prediction, and the results of Experiment 2 were completely consistent with the model.     

Specificity and savings of behavioural habituation over a series of intra- and inter-modal stimuli

A series of four tone stimuli, differing either in tonal frequency or in melody, was presented at the rate of one presentation per day to a group of rats. Habituation was specific to the frequency of simple auditory stimuli and to the melody of patterned stimuli, as shown both by the distraction to stimulus change, and by the trials to habituate to the new stimulus. Savings in habituation occurred when a series of tone stimuli was presented, but was not found for a series of inter-modal stimuli.
