The link between amphibole aluminum content and reaction rim mineralogy

Creator:: Ellingwood, Ross T.
Abstract:: During volcanic eruptions ascending magma undergoes decompression, resulting in a decrease of dissolved H2O. This creates unstable conditions for the hydrous mineral amphibole. As a result a reaction rim forms from anhydrous minerals such as pyroxene, plagioclase, and Fe-Ti oxides (Rutherford and Hill, 1993). There have been numerous studies done...

Memory for emotional faces: Are angry faces more memorable than happy faces?

Creator:: Burros, Alison, Herdener, Nathan, and Lien, Mei-Ching
Abstract:: Previous studies have suggested that negatively valenced faces (e.g., angry faces) automatically capture attention away from faces with other emotional valences (e.g., happy faces and neutral faces). The present study evaluated whether this attentional bias enhances memory of the negative emotional faces. Participants first performed a gender discrimination task on...
