Speech Sound Categories Affect Lexical Competition: Implications for Analytic Auditory Training.

Objectives: We provide a novel application of psycholinguistic theories and methods to the field of auditory training to provide preliminary data regarding which minimal pair contrasts are more difficult for listeners with typical hearing to distinguish in real-time.

Design: Using eye-tracking, participants heard a word and selected the corresponding image from a display of four: the target word, two unrelated words, and a word from one of four contrast categories (i.e.

Nonconsensual Dissemination of Sexual Images Among Adolescents: Associations With Depression and Self-Esteem.

The nonconsensual dissemination of sexual images is a form of image-based sexual abuse that is relatively common among adolescents. However, literature on this issue with adolescent samples is relatively scarce. Therefore, this study is aimed at investigating how this phenomenon varies based on gender and sexual orientation, along with its association with depression and self-esteem.

Dublin Anti-Bullying Self-Efficacy Models and Scales: Development and Validation.

Literature on anti-bullying programs shows a growing consensus about promoting victims and bystanders' self-efficacy against bullying, but provides no theoretical model nor measurement scale to assess the extent of achieving this aim. The current research aims to address these theoretical and empirical gaps by proposing the Dublin Anti-Bullying Self-Efficacy Models and Scales, using a convenience sample of 14-year-old students in Ireland ( = 1,100). After establishing both content and face validity, four separate scales were tested to measure anti-bullying self-efficacy beliefs among offline victims (20-item), online victims (20-item), offline bystanders (20-item), and online bystanders (20-item).

Effects of cholesterol on the structure and collapse of DPPC monolayers.

Cholesterol induces faster collapse by compressed films of pulmonary surfactant. Because collapse prevents films from reaching the high surface pressures achieved in the alveolus, most therapeutic surfactants remove or omit cholesterol. The studies here determined the structural changes by which cholesterol causes faster collapse by films of dipalmitoyl phosphatidylcholine, used as a simple model for the functional alveolar film.

Ancient DNA at the edge of the world: Continental immigration and the persistence of Neolithic male lineages in Bronze Age Orkney.

Orkney was a major cultural center during the Neolithic, 3800 to 2500 BC. Farming flourished, permanent stone settlements and chambered tombs were constructed, and long-range contacts were sustained. From ∼3200 BC, the number, density, and extravagance of settlements increased, and new ceremonial monuments and ceramic styles, possibly originating in Orkney, spread across Britain and Ireland.
