Perceptual organization and apparent brightness in subjective contour figures

According to a number of theories subjective contours arise from brightness contrast and/or assimilation. The apparent brightness gradients generated by these effects are assumed to give rise to the perception of contours delineating the gradients. A study is reported in which naive observers were shown a subjective contour display and asked to report what they saw. They were then asked to judge whether the center or the surround of the display appeared brighter. Subjects whose reports indicated that they had seen the subjective contour figure showed an overwhelming preference for the center of the display being brighter than the surround. However, subjects who did not see the subjective contour figure did not differ significantly in their selection of the center over the surround. This finding presents difficulties for any theory which derives subjective contours from the apparent brightness difference.     

Women's Perceptions of the Prison Environment: When Prison is "the safest place i've ever been"

Incarcerated women's perceptions of the prison environment were explored with respect to relative level of safety from interpersonal abuse in prison as compared to before incarceration. Perceived levels of safety were analyzed based on reported past experiences of interpersonal violence. Participants were 65 women incarcerated in a medium security prison for women with mental and physical health problems. Women's perceptions of safety were evaluated using close–ended quantitative and open–ended qualitative self–report questions. The results suggest that, for some women, prison may be a relatively safe environment and that perceived level of safety may vary with the extent of previous experience of interpersonal violence in childhood and adulthood. Given that the structure of correctional institutions often incorporates abusive dynamics, the directionality of the findings is theoretically and socially important. The patterns apparent in these data are also consistent with other research and theory on the experiences of incarcerated women.
