Previous work suggests that threat-related stimuli are stored to a greater degree in working memory compared to neutral stimuli. However, most of this research has focused on stimuli with physically salient threat attributes, failing to account for how a “neutral” stimulus that has acquired threat-related associations through differential aversive conditioning influences working memory. The current study examined how differentially conditioned safe and threat stimuli are stored in working memory relative to a novel, non-associated stimuli. Participants completed a differential fear conditioning (...) task followed by a change detection task consisting of three conditions across two loads. Results revealed individuals successfully learned to distinguishing CS+ from CS– conditions during the differential aversive conditioning task. Our working memory outcomes indicated successful load manipulation effects, but no statistically significant differences in accuracy, response time, or Pashler’s K measures of working memory capacity between CS+, CS–, or N conditions. However, we observed significantly reduced RT difference scores for the CS+ compared to CS– condition, indicating greater RT differences between the CS+ and N condition vs. the CS– and N condition. These findings suggest that differentially conditioned stimuli have little impact on behavioral outcomes of working memory compared to novel stimuli that had not been associated with previous safe of aversive outcomes, at least in healthy populations.

The purpose of this essay is to investigate and critically analyse some of the formative factors which led to the spiritual maturation of a leading Vīraśaiva saint, Basava. This inquiry focuses on a single event in the life of this great reformer of medieval times, i.e. his spiritual conflict leading to his rejection of the upanayana ceremony. The study will proceed through an investigation of the earliest and subsequent sources which veil the personality of Basava. The traditional view will be (...) challenged as one-sided. By critically comparing the sources, a more comprehensive and plausible account will be suggested. (shrink)

The author replies to a letter to the editor from Felicitas Sofia Holzer concerning Wenner’s article “The Social Value Requirement in Research: From the Transactional to the Basic Structure Model of Stakeholder Obligations,” in the Hastings Center Report’s January‐February 2019 issue.

This is the first of a series of commentaries on the works of the latest Heidegger; all of Heidegger's works published by Neske of Pfullingen since 1954 will be presented and interpreted in the series. The expository plan announced in the editor's preface calls for three-part commentaries, with the first part summarizing the work in question, the second presenting glosses of lines or paragraphs as required by their respective importance, and the third giving philological exegesis of texts also as required (...) in the judgment of the editors. The interpretative inspiration is generally traditional, with more emphasis given to themes with echoes in medieval and modern rationalism and in Italian and French ontologism. The editors adopt Heidegger's characteristic attitude in his latter period, his relinquishing of all objective or subjective idealistic presuppositions. Ontology thus becomes the unveiling of the conditions of possibility of Dasein's speech as truth-making. In Being and Time these conditions of possibility were given in the fundamental ontology and reached their existential expression in resolve. In Gelassenheit Dasein has become a mere instrumentality for the ultimate sense of Being to come to pass. The conditions of possibility of the new Dasein are well understood and highlighted by Landolt. Their existential expression is a new temporal tension within the Dasein, that of Warten or attending. If resolve was the modal intentionality of authentic Dasein, attending is the modal intentionality of poetic symbolic Dasein. Landolt does not seem to have been sufficiently critical of the reflective character of this new intentionality. Can it adequately ground essence, fact and freedom? The techniques of this commentary often depart from hermeneutical respect for the text.--A. M. (shrink)

Next SectionOne of the major concerns about surrogacy is the potential harm that may be inflicted upon the surrogate mother and the child after relinquishment. Even if one were to take the liberal view that surrogacy should be presumptively allowed on the basis of autonomy and/or compassion, evidence of harm must be taken seriously. In this paper I review the evidence from psychological studies on the effect that relinquishing a child has on the surrogate mother and while it appears that (...) many surrogates are able to cope with relinquishment, I argue that there are good reasons, grounded in empirical evidence, to support the view that the subsequent management of the relinquishment necessarily objectifies the surrogate mother.
