SCIENCE MEETS BIBLICAL EXEGESIS IN THE GALILEO AFFAIR

Abstract Although Galileo's venture into theology, as discussed by McMullin, is limited to Galileo's exegesis of Scripture, it can be seen as an important element in a broader role in theology, namely in ecclesiology and in the development of doctrine. From the Council of Trent, the Reformation Council, until today there has been a development in the Church concerning the manner in which Sacred Scripture should be interpreted and as to whether it can be said to be in conflict with our scientific knowledge of nature. Galileo made a significant contribution to this development. With his telescopic observations he was, in fact, undermining the prevailing Aristotelian natural philosophy of his day and was defending the birth of modern science against a mistaken view of Scripture. The Church of his time was not prepared to accept his contribution to this theological development. What does this history have to contribute to the challenges we face today in the interactions between science and religious belief?     

Time to Guide: Evidence for Delayed Attentional Guidance in Contextual Cueing

Contextual cueing experiments show that, when displays are repeated, reaction times (RTs) to find a target decrease over time even when the observers are not aware of the repetition. Recent evidence suggests that this benefit in standard contextual cueing tasks is not likely to be due to an improvement in attentional guidance (Kunar, Flusberg, Horowitz & Wolfe, 2007). Nevertheless, we ask whether guidance can help participants find the target in a repeated display, if they are given sufficient time to encode the display. In Experiment 1 we increased the display complexity so that it took participants longer to find the target. Here we found a larger effect of guidance than in a condition with shorter RTs. Experiment 2 gave participants prior exposure to the display context. The data again showed that with more time participants could implement guidance to help find the target, provided that there was something in the search stimuli locations to guide attention to. The data suggest that although the benefit in a standard contextual cueing task is unlikely to be a result of guidance, guidance can play a role if it is given time to develop.     

Old Testament and Church Ministries in Two Ecumenical Dialogues

Abstract: To understand any church institution as founded by Jesus, one must take account of its relationship to his work of bringing the Old Testament revelation and its institutions to their eschatological realization. A sample of the work of recent ecumenical dialogues (BEM and the international Lutheran– Roman Catholic document on church and justification) shows that their discussions of church institutions have failed to do this adequately. This failure has complicated the efforts at unity to which these dialogues intend to contribute. Attention to the Old Testament roots of church institutions can help ecumenical ecclesiology to focus better on some important issues.     

Are things that are hard to physically move also hard to imagine moving?

Are objects that are more difficult to physically manipulate also more difficult to mentally manipulate? In our study, participants interacted with wooden objects modeled after the figures from Shepard and Metzler’s (1971) classic mental rotation experiment. One pair of objects was easy to physically rotate while another pair was difficult. They then completed a standard mental rotation task on images of these objects. Participants were slower to mentally rotate objects that were harder to physically rotate when they engaged in motor imagery. Further, this cost accrued with increasing angles of rotation. We verified this was the result of motor imagery by showing that the costs can be eliminated by using a strictly visual imagery strategy (imagining the objects moving on their own). These results reveal a striking constraint imposed by our real-world motor experiences on mental imagery, and also demonstrate a way that we can overcome such constraints.     

Does contextual cuing guide the deployment of attention?

Contextual cuing experiments show that when displays are repeated, reaction times to find a target decrease over time even when observers are not aware of the repetition. It has been thought that the context of the display guides attention to the target. The authors tested this hypothesis by comparing the effects of guidance in a standard search task with the effects of contextual cuing. First, in standard search, an improvement in guidance causes search slopes (derived from Reaction Time x Set Size functions) to decrease. In contrast, the authors found that search slopes in contextual cuing did not become more efficient over time (Experiment 1). Second, when guidance was optimal (e.g., in easy feature search), they still found a small but reliable contextual cuing effect (Experiments 2a and 2b), suggesting that other factors, such as response selection, contribute to the effect. Experiment 3 supported this hypothesis by showing that the contextual cuing effect disappeared when the authors added interference to the response selection process. Overall, the data suggest that the relationship between guidance and contextual cuing is weak and that response selection can account for part of the effect.
