The Human Body as Corpus Absconditum

ABSTRACT

One of the most compelling scientific issues of our generation is the Search for Extraterrestrial Intelligence. The question of whether we are alone in the universe has long fascinated the media and the public and has received fresh momentum in the discovery of exoplanets, a small minority of which have Earth like characteristics. The discovery of life elsewhere in the universe, especially if it is intelligent, asks major but fruitful questions of the Christian tradition in areas such as creation, incarnation, redemption and the nature of what it means to be human. Theological work is needed now rather than being left as a future possibility.     

On the visual span during object search in real-world scenes

The current study investigated from how large a region around their current point of gaze viewers can take in information when searching for objects in real-world scenes. Visual span size was estimated using the gaze-contingent moving window paradigm. Experiment 1 featured window radii measuring 1, 3, 4, 4.7, 5.4, and 6.1°. Experiment 2 featured six window radii measuring between 5 and 10°. Each scene occupied a 24.8 × 18.6° field of view. Inside the moving window, the scene was presented in high resolution. Outside the window, the scene image was low-pass filtered to impede the parsing of the scene into constituent objects. Visual span was defined as the window size at which object search times became indistinguishable from search times in the no-window control condition; this occurred with windows measuring 8° and larger. Notably, as long as central vision was fully available (window radii ≥ 5°), the distance traversed by the eyes through the scene to the search target was comparable to baseline performance. However, to move their eyes to the target, viewers made shorter saccades, requiring more fixations to cover the same image space, and thus more time. Moreover, a gaze-data based decomposition of search time revealed disruptions in specific subprocesses of search. In addition, nonlinear mixed models analyses demonstrated reliable individual differences in visual span size and parameters of the search time function.     

A RELATIVISTIC ESCHATOLOGY: TIME,ETERNITY, AND ESCHATOLOGY IN LIGHT OF THE PHYSICS OF RELATIVITY

Unique epistemological challenges arise whenever one embarks on the critical and self‐critical reflection of the nature of time and the end of time. I attempt to construct my preference for an eschatological distinction between time and eternity from within a middle way, avoiding both the hubris that claims complete comprehension and the resignation that concedes readily to know nothing. Surveying the history of reflection on this multifaceted question of time, with its ephemeral and everlasting dimensions, I argue that the eschatological interplay between the “already” and the “not yet” has much to offer: promise for the religion‐science dialogue as well as hope for humanity, especially for those on society's bleakest edges. But understandings of time, to be authentically theological, must be also informed by cosmology and the physics of relativity. My proposal seeks to respect the theological and scientific interpretations of the nature of time, serving the ongoing, creative interaction of these disciplines. Between physics and theology I identify four formal differences in analyzing eschatology, all grounded in the one fundamental difference between extrapolation and promise. Discussion of what I term deficits in both the scientific and theological approaches leads to further examination of the complex relationship between time and eternity. I distinguish three models of such relationships, which I label the ontological, the quantitative, and the eschatological distinction between time and eternity. Because of the way it embraces a multiplicity of times, especially relating to the culmination and the consummation of creation, I opt for the eschatological model. The eschatological disruption of linear chronology relates well to relativ‐istic physics: This model is open, dynamic, and relational, and it may add a new aspect to the debate over the block universe.     

Exploring Diurnal Cortisol Rhythms of Kindergarten Teachers in Kosovo and Ukraine

Teachers’ stress is a dynamic combination of the individual teacher's characteristics and characteristics of the classroom and school environment. To date, there are limited studies on teachers’ stress in the context of lower‐middle‐income countries (LMICs), where working conditions as well as general political and economic circumstances might pose a considerable threat for teachers’ well‐being. This study explores whether certain combinations of individual and environmental experiences of teachers in LMICs may result in stress, assessed as patterns of diurnal cortisol rhythm. Participants were kindergarten teachers in Kosovo and Ukraine, two LMICs in Europe. Latent Profile Analysis identified three subgroups of teachers that significantly differed on teachers’ education and experience. Preliminary results of Latent Growth Modeling suggested differences between profiles in baseline waking cortisol and patterns of diurnal decline. Teachers in the profile that was characterized by the longest experience working in the field but the lowest level of education showed blunted cortisol in the morning and a flatter slope; a pattern that could indicate a maladaptive cortisol response. Future directions for studying stress processes among teachers in LMICs and implications for policy and practice on how to support teacher well‐being in low‐resource contexts are discussed.     

Unambiguous generalization effects after treatment of non-canonical sentence production in German agrammatism

Agrammatism is-among others, characterized by a deficit in producing grammatical structures. Of specific difficulty is the utilization of complex, non-canonical sentence structures (e.g. object-questions, passives, object-clefts). Several studies have documented positive effects when applying a specific treatment protocol in terms of increasingly correct production of target complex sentence structures with some variance in generalization patterns noted across individuals. The objective of this intervention study was to evaluate an intervention program focussing on the production of non-canonical sentences. Hypotheses about the occurrence of treatment effects were formulated on the basis of syntactic complexity, referring to the amount of syntactic phrase structures necessary to generate specific German sentence structures. A multiple single case study with seven agrammatic participants was applied, each participant receiving training in the production of object-relative-clauses and who-questions. The investigation was designed to unambiguously evaluate for each individual, structure specific and generalized learning effects with respect to the production of object-relative-clauses, who-questions and passive sentences. Results showed significant improvements for all sentences types. This outcome is considered within methodological issues of treatment studies. Theoretical and clinical implications are discussed.     

Word for word: Multiple lexical access in speech production

We report an experiment in which we test the possible influence of the tense of the verb and explicit negatives with indicative conditionals. We tested the effects of systematically negating the constituents of four fundamental inferences based on conditionals in three different tenses (present tense, past tense, future tense): Modus Ponens (i.e., inferences of the form: if p then q; p; therefore q), Modus Tollens (if p then q; not-q; therefore not-p), Affirmation of the Consequent (if p then q; q; therefore p), and Denial of the Antecedent (if p then q; not-p; therefore not-q). The latter two inferences are invalid for true conditionals, but are valid for bi-conditionals (if, and only if, p then q). The participants drew their own conclusions from premises about letters and numbers on cards. We discuss the results in relation to an affirmation premise bias, a negative conclusion bias, and a double negation effect. We outline the importance of our findings for theories about conditional and counterfactual thinking.
