The role of vision in auditory distance perception

In humans, multisensory interaction is an important strategy for improving the detection of stimuli of different nature and reducing the variability of response. It is known that the presence of visual information affects the auditory perception in the horizontal plane (azimuth), but there are few researches that study the influence of vision in the auditory distance perception. In general, the data obtained from these studies are contradictory and do not completely define the way in which visual cues affect the apparent distance of a sound source. Here psychophysical experiments on auditory distance perception in humans are performed, including and excluding visual cues. The results show that the apparent distance from the source is affected by the presence of visual information and that subjects can store in their memory a representation of the environment that later improves the perception of distance.     

Adopted Individuals’ Views on the Utility and Value of Expanded Carrier Screening

Adoptees may not have family medical history and ethnicity information. Carrier screening assesses reproductive risk. Expanded carrier screening (ECS) screens for many genetic conditions regardless of a patient’s knowledge of family history and ethnicity. This study aimed to better understand the opinions and attitudes of adopted individuals on the use of ECS in determining a patient’s reproductive genetic risks. Specifically, the study assessed how adopted individuals feel that results of ECS may be useful to them and whether adoptees feel that meeting with a genetics professional in the process of undergoing ECS would be useful. Adult adoptees (N?=?124) were recruited online. Their opinions on ECS were explored. The majority reported they had never been offered carrier screening (92%). The majority of adoptees wanted ECS (76%). Neither the amount of contact with biological relatives nor having medical knowledge about biological relatives was significantly associated with adoptees’ desire to pursue ECS. There was a significant positive correlation between adoptees of higher education levels and the amount they would pay for ECS (p?=?0.004). The majority of participants (95%) indicated a genetics professional would be helpful when undergoing ECS. The findings suggest this population may want ECS and support from genetics healthcare professionals. Advocacy for genetic counseling and testing for adoptees appears justifiable.     

Foucault and Derrida: The Question of Empowering and Disempowering the Author

This article focuses on Michel Foucault’s concepts of authorship and power. Jacques Derrida has often been accused of being more of a literary author than a philosopher or political theorist. Richard Rorty complains that Derrida’s views on politics are not pragmatic enough; he sees Derrida’s later work, including his political work, more as a “private self-fashioning” than concrete political thinking aimed at devising short-term solutions to problems here and now. Employing Foucault’s work around authorship and the origins of power, I show that Derrida is indeed fashioning himself. This self-fashioning is not merely private or fanciful. Rather, I argue that Derrida can be read as employing what Foucault would call “technologies of the self” to not only show the play of possibility and impossibility at work in all politics and thought, but also to use his savoir to create two important and potentially constructive power structures. First, there is the power of deconstruction itself as a “militant critique” that calls for a forceful and irreducible justice. Second, there is the power of Derrida himself, understood as leaving behind a legacy of himself as the “originator” of deconstruction and as a public intellectual.

The conflict of harmony: Intergroup contact,commonality and political solidarity between minority groups

Recent work on social change has complicated the picture regarding the influence of intergroup contact with majority groups on minority group members' perceptions of inequality and willingness to engage in social action. The present research investigated the ability of a commonality-focused message to inspire political solidarity between minority groups, as well as the potential moderating role of intergroup contact with a majority group on the efficacy of this message for political solidarity. Across two experiments, as hypothesized, political solidarity from one minority group to another was highest within a commonality condition, relative to group-boundaries salient and control conditions, which was explained by increases in commonality perceptions. As expected, however, these effects were moderated by majority group contact, such that those with high levels of contact with majority group were less likely to show the commonality-to-political solidarity relation. Implications for intergroup contact and more broadly social change are discussed.     

A place for the role of community in the structure of the state: Edith Stein and Edmund Husserl

This essay argues that Stein’s view of the state can overcome Husserl’s skepticism about the state being an authentic, intense community rooted in solidarity while not negating his hope for the advent of a genuinely ethical, rational culture. Whereas Husserl places rationality and freedom within the framework of culture proper and not in the state, Stein sees the state as an extension of persons that can give the state its own free, deliberating and rational Ich kann.
