Abstract. Central to the work of Arthur Peacocke on science and religion is the intention to develop a reasonable faith within an intelligible framework of meaning. Showing the inadequacy of reductionism is necessary for this purpose. Knowledge of God is related to what science can tell us about creation. From an evolutionary framework, characterized as a delicate balance that issued in humans, and manifested through contingency and chance, God's actions are expressed as exploring the potentialities of creation. The creation is understood to be in God, but God is more than the world, as in panentheism. God suffers with the creation in love, and the focus of human meaning is expressed in Jesus Christ, the Incarnation, the sacrament of God.  相似文献

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group.  相似文献

Goodman's (1979, 1981, 1985) loglinear formulation for bi-way contingency tables is extended to tables with or without missing cells and is used for exploratory purposes. A similar formulation is done for three-way tables and generalizations of correspondence analysis are deduced. A generalized version of Goodman's algorithm, based on Newton's elementary unidimensional method is used to estimate the scores in all cases.This research was partially supported by National Science and Engineering Research Council of Canada, Grant No. A8724. The author is grateful to the reviewers and the editor for helpful comments.  相似文献

Abstract. It is misleading to speak of warfare between science and Christian theology, as Andrew White did in 1896. White also was mistaken in exaggerating the conflict between the church and Galileo and Copernicus. The more important issue between science and theology has to do with the mechanistic interpretation of nature. When he introduced the principle of inertia in his natural philosophy, René Descartes insisted that God's immutability renders it impossible for God to intervene in the creation. He reduced the idea of God to a deistic notion by speaking of motion exclusively as a property of bodies. Even though Isaac Newton offered a different view, the Cartesian view dominated subsequent thinking. This made dialogue with theology difficult. Michael Faraday, followed by Albert Einstein, introduced the idea of field; bodily phenomena were subordinated as manifestations of fields. The precursor of the idea of field is the Stoic idea of spirit, which is close to the biblical concept of spirit. Thomas Torrance and I have taken this concept of field as an occasion to reopen dialogue. Mechanistic thinking accounts for the tension between Darwinian thought and theology. In principle the tension can be resolved, because the Bible itself asserts that all living things were brought from the earth—that is, organic life emerged from inorganic matter. Thus, emergence, contingency, and novelty are consistent with Darwinian evolutionary thinking. Contingency can be related conceptually to the activity of God in creation.  相似文献

Concurrent schedules may be viewed as consisting of two pairs of stay and switch schedules, each pair associated with one of the alternatives. A stay schedule arranges reinforcers for staying and responding at one alternative, whereas the associated switch schedule arranges reinforcers for switching to the other alternative. In standard concurrent schedules, the stay schedule at each alternative is equivalent to the switch schedule at the other alternative. MacDonall (1999) exposed rats to one pair of stay and switch variable-ratio schedules and varied the response requirements across conditions. Combining results from symmetric pairs produced composite performances that were described by the generalized matching law. This outcome was noteworthy because the data were obtained from performances at two alternatives with contingencies that were functionally unrelated to each other. This result suggests that concurrent performances may consist of two unrelated performances that alternate as behavior moves between alternatives. The purpose of the present experiment was to extend those results to interval schedules. Rats were exposed to pairs of random-interval schedules, and across conditions their mean intervals were varied. When data from appropriately paired conditions were combined, the composite performances were consistent with the generalized matching law. In addition, the results supported two models of concurrent performances that were based on local variables at an alternative (behavior, and stay and switch reinforcers): a modified version of the contingency discrimination model (Davison & Jenkins, 1985) and the local model (MacDonall, 1999).  相似文献

Six pigeons were trained in sessions composed of seven components, each arranged with a different concurrent-schedule reinforcer ratio. These components occurred in an irregular order with equal frequency, separated by 10-s blackouts. No signals differentiated the different reinforcer ratios. Conditions lasted 50 sessions, and data were collected from the last 35 sessions. In Part 1, the arranged overall reinforcer rate was 2.22 reinforcers per minute. Over conditions, number of reinforcers per component was varied from 4 to 12. In Part 2, the overall reinforcer rate was six per minute, with both 4 and 12 reinforcers per component. Within components, log response-allocation ratios adjusted rapidly as more reinforcers were delivered in the component, and the slope of the choice relation (sensitivity) leveled off at moderately high levels after only about eight reinforcers. When the carryover from previous components was taken into account, the number of reinforcers in the components appeared to have no systematic effect on the speed at which behavior changed after a component started. Consequently, sensitivity values at each reinforcer delivery were superimposable. However, adjustment to changing reinforcer ratios was faster, and reached greater sensitivity values, when overall reinforcer rate was higher. Within a component, each successive reinforcer from the same alternative (\"confirming\") had a smaller effect than the one before, but single reinforcers from the other alternative (\"disconfirming\") always had a large effect. Choice in the prior component carried over into the next component, and its effects could be discerned even after five or six reinforcement and nonreinforcement is suggested.  相似文献

We used response-restriction (RR) assessments to identify the preferences of 7 individuals with mental retardation for a variety of vocational and leisure activities. We subsequently increased their engagement in nonpreferred activities using several procedures: response restriction per se versus a Premack-type contingency (Study 1), supplemental reinforcement for engagement in target activities (Study 2), and noncontingent pairing of reinforcers with nonpreferred activities (Study 3). Results indicated that preferences are not immutable and can be altered through a variety of relatively benign interventions and that the results of RR assessments may be helpful in determining which types of procedures may be most effective on an individual basis.  相似文献

The purpose was to assess infants' sensitivity to social contingency, taking affective state into account, during face‐to‐face interaction with the mother in a double video set‐up. Infants' behaviour during three sequences of live face‐to‐face interaction were compared to two sequences where the interaction between the infant and the mother was set out of phase, by presenting either the infant or the mother with a replay of their partners' behaviour during earlier live interaction. We found a significant negative correlation between the infant's degree of negative affect and the average time of looking at the mother during the live sequences. A median split was calculated to separate the infants into a high‐negative‐affect group and a low‐negative‐affect group on the basis of their emotional responses during the experiment. The low‐negative‐affect infants looked significantly more at their mothers than other foci during the live but not the replay sequences, while the high‐negative‐affect infants did not show this difference. The results suggest that 2–4‐month old infants are able to distinguish between experimental distortion of contingent aspects in live and replay sequences, but that this effect of the replay condition may not be shown by moderate to highly distressed infants. Our findings underline the importance of taking infants' emotional state into account in experiments intended to assess their capacity for intersubjective communication.

Fifty-eight smokers received abstinence-contingent monetary payments for 1 (n  =  15) or 14 (n  =  43) days. Those who received contingent payments for 14 days also received 0, 1, or 8 experimenter-delivered cigarette puffs on 5 evenings. The relative reinforcing effects of smoking were assessed in a 3-hr session on the final study day, when participants made 20 choices between smoking or money. The reinforcement contingencies exerted robust control over smoking, and programmed smoking lapses produced few discernible effects. These results further illustrate the robust control that reinforcement contingencies can exert over cigarette smoking and suggest that any effects of lapses on the relative reinforcing effects of smoking are modest under conditions involving abstinence-contingent reinforcement contingencies.  相似文献
