The hollow-face illusion, in which a mask appears as a convex face, is a powerful example of binocular depth inversion occurring with a real object under a wide range of viewing conditions. Explanations of the illusion are reviewed and six experiments reported. In experiment 1 the detrimental effect of figural inversion, evidence for the importance of familiarity, was found for other oriented objects. The inversion effect held for masks lit from the side (experiment 2). The illusion was stronger for a mask rotated by 90° lit from its forehead than from its chin, suggesting that familiar patterns of shading enhance …

The purpose of this study was to assess university students’ self-reported knowledge, behavior, and behavioral intention regarding H1N1 influenza. Participants included students at a major university in the southwestern US. Data were collected in early spring 2010 through a 24-item selfadministered survey. Outcome variables included knowledge, behavior and intention. A total of 483 students participated. Most reported trying to prevent H1N1 influenza though specific behaviors. Many lacked knowledge about symptoms and treatment; a few (10%) had been vaccinated; and half had no intention of getting vaccinated or practicing self-isolation. Gender and age were significantly associated with the three outcome variables. …
