Gender differences in acute and chronic stress in Wistar Kyoto (WKY) rats

While females are considered more susceptible to depressive behavior, this assertion is not strongly supported by the experimental literature. Since stress contributes to depressive behavior, male and female Wistar Kyoto (WKY) rats were exposed to either one session (acute stress) or 5 sessions (chronic stress) of restraint plus cold in order to study depressive behavior in male and female rats. After their respective treatment exposure, rats were tested in the open field test (OFT) and for retention of a passive-avoidance (P-A) task. One stress session resulted in significant immobility in the OFT for males, whereas 5 sessions were required to produce similar immobility in female rats. Acute stress interfered with the retention of the P-A response for males, while both acute and chronic stress produced poor P-A responses in female rats. Food consumption decresed, progressively, as a function of stress sessions, in female rats, whereas feeding in males returned to control levels after five stress days. Both acute and chronic stress exacerbated the stress ulcer response in male rats, but not in female rats. Chronic, but not acute, stress resulted in an increase in serotonin transporter mRNA levels in the dorsal raphe nucleus of both male and, female rats. The general consensus from these data suggested that female rats were more vulnerable to chronic stress and consequently supported the notion that females may be more susceptible to stress induced behavioral depression.     

THE DOCTRINE OF CREATION AND MODERN SCIENCE

Abstract. In contrast to Christian theology that has ignored science, this essay suggests that a credible doctrine of God as creator must take into account scientific understandings of the world. The introduction of the principle of inertia into seventeenth-century science and philosophy helped change the traditional idea of God as creator (which included divine conservation and governance) into a deist concept of God. To recapture the idea that God continually creates, it is important to affirm the contingency of the world as a whole and of all events in the world. Reflecting on the interrelationship of contingency and natural law provides a framework for relating scientific theories of a universal field, the concept of emergent evolution, and the theological concept of eternal divine spirit active in all creation.     

FIELD REPLICATION OF CLASSWIDE PEER TUTORING

We conducted a large-scale field replication study of classwide peer tutoring applied to spelling instruction (Greenwood, Delquadri, & Hall, 1984). Two hundred and eleven inner-city students in four schools participated during their first- and second-grade school years. The effects of classwide peer tutoring were compared to teacher instructional procedures and pretest probes using a group replication design (Barlow, Hayes, & Nelson, 1984). Analysis of group and individual results indicated that (a) both teacher instructional procedures and classwide peer tutoring were effective in increasing spelling performance above pretest levels, (b) peer tutoring produced statistically greater gains relative to the teachers' procedures for both low and high student groups formed on pretest levels, (c) these outcomes were representative of groups, classes, individuals, and years during the project, and (d) participant satisfaction with the program was generally high. A separate analysis of the social importance of treatment outcome revealed differential findings for low and high groups related to pretest levels. Implications of these findings are discussed.     

Learning phonology with substantive bias: an experimental and computational study of velar palatalization

There is an active debate within the field of phonology concerning the cognitive status of substantive phonetic factors such as ease of articulation and perceptual distinctiveness. A new framework is proposed in which substance acts as a bias, or prior, on phonological learning. Two experiments tested this framework with a method in which participants are first provided highly impoverished evidence of a new phonological pattern, and then tested on how they extend this pattern to novel contexts and novel sounds. Participants were found to generalize velar palatalization (e.g., the change from [k] as in keep to [t⌢∫S] as in cheap) in a way that accords with linguistic typology, and that is predicted by a cognitive bias in favor of changes that relate perceptually similar sounds. Velar palatalization was extended from the mid front vowel context (i.e., before [e] as in cape) to the high front vowel context (i.e., before [i] as in keep), but not vice versa. The key explanatory notion of perceptual similarity is quantified with a psychological model of categorization, and the substantively biased framework is formalized as a conditional random field. Implications of these results for the debate on substance, theories of phonological generalization, and the formalization of similarity are discussed.     

Crossfostering in mice selectively bred for high and low levels of open-field thigmotaxis

The main purpose of this research was to investigate whether the difference in open-field (OF) thigmotaxis between mice selectively bred for high and low levels of wall-seeking behavior originated from genetic or acquired sources. Unfostered, infostered, and crossfostered mice were compared in two experiments in which the effects of strain, sex, and fostering on ambulation, defecation, exploration, grooming, latency to move, radial latency, rearing, thigmotaxis, and urination were studied. These experiments revealed that OF thigmotaxis was unaffected by the foster condition and thus genetically determined. The selected strains of mice also diverged repeatedly with regard to exploration and rearing. The findings are in line with the previously described existence of an inverse relationship between emotionality and exploration.     

Revisiting Religious Ethics as Field and Discipline

Returning to John P. Reeder's 1978 essay on “Religious Ethics as a Field and Discipline,” this essay explores debates surrounding the original intentions for the Journal of Religious Ethics (JRE) and for the field of religious ethics, as these have played out over the decades among an influential group of scholars involved with the JRE since its inception: Arthur Dyck, Ronald Green, Stanley Hauerwas, and Jeffrey Stout. While the JRE and its founding mission are in need of ongoing critique and transformation, we might well still affirm the journal's ongoing importance as a site for the negotiation of a commons, the identification of possibilities for shared life, imagined beyond exclusion and domination.     

THEOLOGICAL APPROPRIATION OF SCIENTIFIC UNDERSTANDINGS: RESPONSE TO HEFNER, WICKEN, EAVES, AND TIPLER

Abstract. Philip Hefner's focus on contingency and field as the guiding concepts in my thinking and his characterization of my theological enterprise as a Lakatosian research program are appropriate and helpful.
I welcome Jeffrey Wicken's holistic approach to the emergence of life. Theology can appropriate the language of self-organizing systems exploiting the thermodynamic flow of energy degradation for interpreting organic life as a creation of the Spirit of God.
However, I cannot sympathize with Lindon Eaves's equation of "hard science" with a reductionism which raises the double helix to the status of icon; the "meaning" of DNA derives from its place in the total phenomenon of life—not the reverse.
Frank Tipler's cosmology raises the prospect of a rapprochement between physics and theology in the area of eschatology. A Christian cosmology, however, would require at least three modifications: contingency in the history of creation; the uniqueness of Jesus' resurrection; and the relation of these to the problem of evil.     

Focal attention and the perception of pattern structure in extrafoveal vision

Several studies have shown that visual attention enhances the encoding of the positional relationships between pattern elements, i.e., the perception of pattern structure. This theoretical note discusses the possibility that the inferiority of extrafoveal vision in the perception of pattern structure results, at least partially, from less effective focal attention in the periphery. Hence, there may exist higher level differences between foveal and extrafoveal vision in information processing which cannot be explained by the spatial inhomogeneity of the retino-striate system.

The Latin American contribution to the psychoanalytic concept of phantasy

The author argues that the ubiquity of phantasies at various levels of mental functioning is undisputed in the current schools of psychoanalytic thought; however, she demonstrates some variations in their understanding of how the psychotherapeutic access to different configurations occurs. In the process of examining and acknowledging the central role played by unconscious phantasies in his patients’ symptoms, Freud gradually broadened the vernacular meaning of the German word ‘Phantasie’ that refers to imagination and the world of imagination, conferring on it the specific features that came to characterize its use in the psychoanalytic vocabulary. Later, the expansion of the concept derived from Melanie Klein’s clinical material obtained from child analyses gave rise to important debates. The author discusses the main points of disagreement that led to these debates, as well as their various theoretical and technical implications. Psychoanalytic associations in Latin America were strongly influenced by Klein and her followers. Thus, most of their scientific writings use the concept of unconscious phantasy put forward by the Kleinian school. Taking Kleinian principles as their starting point, Baranger and Baranger made the most original Latin American contribution to the concept of unconscious phantasy with their works on the unconscious phantasies generated by the analytic pair.
