Learning impairment following insoluble problems: Learned helplessness or altered hypothesis pool?

According to the learned helplessness hypothesis, the learning impairment typically displayed by subjects previously given insoluble problems results from the veridical learning of response-outcome independence. This learning is represented as a belief in helplessness which interferes with the subsequent acquisition of adaptive responses. However, this interpretation is suspect since subjects in a psychology experiment tend not to learn that random relationships are random. Instead, an alternative interpretation of these findings attributes the learning impairment following insoluble problems to a hypothesis pool alteration in the direction of (inappropriately) complex hypotheses. This alternative interpretation tended to be supported ported in Experiment 1, which varied the difficulty of the test task and found the impairment (relative to a no-treatment control) following insolubility to be inversely proportional to the test difficulty. In contrast, Experiment 2 employed a procedure which facilitated the attribution of response-outcome independence and found the impairment following insolubility to be directly proportional to the test difficulty. It was concluded that the results of Experiment 2 represented learned helplessness.     

The similarity-attraction relationship: Is there an ideal one?

It is proposed that we are attracted to similar individuals because: (1) such individuals are similar to our ideals and (2) such individuals are similar to ourselves. Previous studies have employed a similarity manipulation which has confounded these two components. When the components are separated, similarity to the ideal was expected to exert a major influence and similarity to the self a minor influence on attraction. A series of experiments orthogonally manipulated similarity to self and similarity to ideal with a new technique involving content-free dimensions. The results indicated a consistent main effect for ideal similarity on liking and no consistent main effect for similarity to the self. Finally, the results also indicated that given any two of the three variables—similarity to self, similarity to ideal, and own self to own ideal discrepancy—subjects seemed able to infer the other or third variable in a fairly logical fashion.     

ROBERT JOHN RUSSELL VERSUS THE NEW ATHEISTS

This essay compares Robert John Russell's work in his recent book Cosmology from Alpha to Omega: The Creative Mutual Interaction of Theology and Science (2008) to that of the authors known collectively as "the new atheists." I treat the latter as recent contributors to the modern tradition of scientific naturalism. This tradition makes claims to legitimacy on the basis of its close relations to the natural sciences. The purpose of this essay is to show up the poverty of the naturalist tradition's scientific credentials by contrasting it with Russell's careful account of positive relations between science and Christian theology.     

PERCEIVING NATURAL EVIL THROUGH THE LENS OF DIVINE GLORY? A CONVERSATION WITH CHRISTOPHER SOUTHGATE

Finding a way to come to terms with the disvalues in the evolutionary world is a particular challenge in the light of Neo‐Darwinian theories. In this article I trace the shift in Christopher Southgate's work from a focus on theodicy to a theologian of glory. I am critical of his rejection of the tradition of the Fall, his incorporation of disvalues into the work of divine Glory, and the specific theological weight given to scientific content. I offer a critique of Holmes Rolston III's approach to the valuation of nature that I believe has influenced Southgate's theology. Constructively, I offer an alternative that seeks to recover an understanding of the origin of evil and the Adamic event that draws on the work of Paul Ricoeur. I also draw on the work of anthropologist Tim Ingold for an alternative philosophical approach to evolution which opens up a space for a recovery of the concepts of creaturely Sophia and shadow Sophia in the work of Sergius Bulgakov.     

TRACING ORIGINS OF TWENTY‐FIRST CENTURY ECOTHEOLOGY: THE POETRY OF CHRISTOPHER SOUTHGATE

With the goal of better understanding how science, religion, and poetic art came together in the work of Christopher Southgate, the authors first explore his spiritual poetry. They come away with a better understanding of the author's commitment to a broad naturalism that contributes, along with his own faith experience, to his prose works in the emerging field of ecotheology. The authors conclude that Southgate's work is part of the worldwide emergence of a theological rationale that supports environmentalism, the protection of species, and the conservation of biodiversity. The authors find Southgate's poetry warm, appealing, accessible, and re‐readable to good effect, but with a thread of danger and warning throughout. Both features are quite appropriate for the environmental movement in the twenty‐first century.     

ESSAYS IN HONOR OF CHRISTOPHER SOUTHGATE: INTRODUCTION

This article is an introduction to the special issue of Zygon in honor of Christopher Southgate. Over the years he has made many significant contributions to the field of science and religion, and contributors have gathered to celebrate him on his sixty‐fifth birthday. This introduction includes some biographical background and an outline of the issue's contents.     

EVOLUTION,CONTINGENCY, AND CHRISTOLOGY

Christopher Southgate has made important contributions to theodicy and the theory of divine action in light of the contingency in evolution and the suffering of creation. What happens then when one thinks through the implications of contingency for Christology? One can admit that aesthetic and moral judgments are products of a contingent history and yet affirm that they really are valid. Similarly, we argue, one can acknowledge the contingency of Jesus’ existence, actions, and subsequent impact and still maintain that his will was uniquely united with the divine will. Following a critical engagement with the recent work of Keith Ward, we argue that a high Christology is compatible with the actual contingencies of evolutionary and social history, without the necessity of interventionist divine action.     

The effect of instructions to organize for good and poor learners

Two studies are reported which investigate the possibility that instructing individuals to organize their recall will differentially facilitate the performance of “fast” and “slow” learners (defined in terms of performance on a pretest). Experiment I utilized alphabetic organization in the free-recall learning of a list of unrelated words; Experiment II used a categorized word list under similar conditions. In each study, half of the individuals in each ability group received instructions, prior to the first of six learning trials, that contained information about the respective nature of organization present in the list and encouragement to use this type of organization in learning the list. In Experiment I, instructions to use alphabetic organization facilitated the performance of both ability groups to about the same extent. In Experiment II, instructions to use categorical organization in learning resulted in a substantial facilitation of performance for “slow” learners and a slight decrement in performance for “fast” learners. The results from the two studies are discussed in terms of sources of individual differences in learning.     

Factors affecting developmental changes in the speed of processing

Although many studies have found developmental changes in the speed of various processes, they have potentially confounded the subject's age with his knowledge of the task domain and use of strategies. In this study, the strategies used by the subject and his domain knowledge were independently assessed by a number of tasks. Subsequently, processing rate measures were obtained for a task (the “same/different” judgment task of simultaneously presented stimuli) in which domain knowledge was manipulated independently of age while controlling for strategy usage. It was found that the usual adult superiority in speed of processing could be markedly reduced if children possessed equivalent amounts of domain knowledge and this effect was domain specific. Further, it was found that differences in knowledge affected processing rates in both knowledgeable adults and children and to about the same extent. It was concluded that some part of the typical adult superiority in processing rate was due to knowledge differences.     

The halo effect revisited: Forewarned is not forearmed

The purpose of the present research was to determine if forewarning subjects about the halo effect eliminated the effect or made people aware of its impact. The research was a replication and extension of R. E. Nisbett and T. D. Wilson's (Journal of Personality and Social Psychology, 1977, 35, 250–256) experiment on the halo effect. Subjects viewed an interview of a college instructor who was either warm or cold and then rated his physical appearance, mannerisms, and French accent. Some subjects were told to introspect about their cognitive processes while viewing the interview and were told that the purpose of the study was to see how aware they were of the determinants of their ratings. Other subjects were also told specifically what the halo effect was and given a motivation either to show it or not to show it. In addition, a measurement technique different from that used by Nisbett and Wilson was utilized to allow a more precise measurement of awareness, and a new cover story was used to make the task more involving and important to subjects. Despite these attempts to eliminate the halo effect (or, at a minimum, to make people aware of it), the results indicated that subjects in all conditions were very susceptible to it. That is, subjects who viewed the warm version of the interview rated the instructor's appearance, mannerisms, and accent significantly higher than did those who viewed the cold version, even when informed and forewarned about this effect. The forewarning and introspection instructions also had no impact on subject's awareness of the halo effect. Subjects in all conditions indicated that their liking for the instructor had had only a minimal effect on their ratings.
