Central vision in the newborn

Newborns' fixations on a 4° dot were longer than their fixations on the comparable part of a blank field. This suggests newborns can detect a stimulus with the fovea or with some part of the retina near the fovea.     

INTRODUCTION: TOWARD A METAPHYSIC OF MEANING

We introduce a two‐part collection of articles (Part 2 to appear in the September 2010 issue) exploring a possible new research program in the field of science and religion. At the center of the program lies an attempt to develop a new theology of nature drawing on the philosophy of C. S. Peirce. Our overall idea is that the fundamental structure of the world is exactly that required for the emergence of meaning and truth‐bearing representation. We understand the emergence of a capacity to interpret an environment to be important to the emergence of life, and we see the subsequent history of biological evolution as a story of increasing capacities for meaning making and meaning seeking. Theologically, we understand God to be the ground of all such meaning making and the ultimate goal of the universe's emerging capacity for interpreting signs. Here we explain our reasons for seeking a new metaphysical framework in which science and theology may each find a home. We survey the contributions to the two‐part collection, and we suggest that the interdisciplinary collaboration from which these have arisen may serve as a methodological model for the field of science and religion.     

One version of direct response priming requires automatization of the relevant associations but not awareness of the prime

Priming is the influence of one event on performance during a second event. One type of priming is known as semantic priming because it biases interpretation of the subsequent stimulus. Another type, direct response priming, biases responding directly without semantic mediation. Research reviewed in this article indicates that two versions of the second type, direct response priming, can be distinguished. One version, explicit priming, requires awareness of the prime. The other version, associative response priming, occurs even if the prime is masked and not phenomenally visible. This version, which is attributed to associations relating specific sensory events to movements of particular muscles, is enabled only if the association has previously been automatized by brief practice in which the to-be-primed response is made to the stimulus that subsequently appears as the prime. Associative response priming can be explained by a simple stimulus–response interpretation; other varieties of priming are more theoretically challenging.     

TRANSFORMING THEOLOGICAL SYMBOLS

In this essay I explore the need for transforming the Christian theological symbols of the Trinity, Incarnation, and Redemption, which arose in the context of neo‐Platonic metaphysics, in light of late modern, especially Peircean, metaphysics and categories. I engage and attempt to complement the proposal by Andrew Robinson and Christopher Southgate (in this issue of Zygon) with insights from the Peircean‐inspired philosophical theology of Robert Neville. I argue that their proposal can be strengthened by acknowledging the way in which theological symbols themselves have a transformative (pragmatic) effect as they are “taken” in context and “break” on the Infinite.     

GOD AND THE WORLD OF SIGNS: INTRODUCTION TO PART 2

We introduce the second part of a two‐part collection of articles exploring a possible new research program in the field of science and religion. At the center of the program lies an attempt to develop a new theology of nature drawing on the philosophy of C. S. Peirce. Our overall idea is that the fundamental structure of the world is exactly that required for the emergence of meaning and truth‐bearing representation. We understand the emergence of a capacity to interpret an environment to be important to the emergence of life, and we see the subsequent history of biological evolution as a story of increasing capacities for meaning‐making and ‐seeking. Theologically, we understand God to be the ground of all such meaning‐making and the ultimate goal of the universe's emerging capacity for interpreting signs. Here we summarize the articles in Part 1, which focused on scientific and philosophical aspects of the research program, and introduce Part 2, which turns to the theological outworking of the project.     

Differences or deficits? The significance of pretend and sociodramatic play

The developmental significance of pretend and sociodramatic play remains unresolved. Quite possibly, such play experiences facilitate a range of developmental competences which other experiences (including focused training) can facilitate equally effectively. If this were so, individual differences in such forms of play need not be a matter of direct concern in themselves. Such differences could be related to proximate variables which would be of greater scientific significance than broader or vaguer social class labels, although the political and economic realities of socioeconomic status should not be forgotten.     

Recall failure following successful generation and recognition of responses by alcoholic Korsakoff patients

Amnesic Korsakoff patients and controls were presented with twelve words, each shown individually in the presence of a weak associate. They were then asked to freely associate to 12 other words that were strong associates of the to-be-remembered (TBR) words. The Korsakoff patients generated, and were able to recognize, as many of the TBR words as the controls. Yet, in spite of this recognition ability, these same patients were subsequently unable to recall the critical TBR words when the weak cues were again presented. A follow-up study found that the same recognition results could be obtained with Korsakoffs months after initial presentation suggesting that the patients might initially have “recognized” the most highly associated words simply because they represented the most probable choices. Intermediate association prompts failed to generate correct responses. It was hypothesized that the Korsakoff patients cannot restructure their semantic associative hierarchy during input in such a way as to become sensitized to other than the strongest associates as prompts during recall.
