New research shows that overall, the prevalence of adverse and positive childhood experiences reported by parents of teenagers hasn’t changed substantially in the United States in recent years. The findings suggest that interventions designed to boost positive family experiences and shield children from negative experiences may not be hitting the mark on a national scale, the study’s authors say.
Living in a neighbourhood where people feel safe and supported is linked to a reduced risk of psychosis among Stockholm residents – but only for people of Swedish or European origin. This is shown in a new study from Karolinska Institutet and UCL published in the journal Nature Mental Health. For people of North African or Middle Eastern origin, an increased risk of psychosis was seen in the same neighbourhoods.
Dr Maria Santacà is a behavioral biologist who specializes in the study of animal cognition and perception. Her research at the Department of Behavioral & Cognitive Biology of the University of Vienna explores how visual illusions can reveal the evolutionary roots of perception, asking whether similarities and differences across species reflect shared ancestry and neural complexity, or unique adaptations to ecological and social environments. In a newly published Frontiers in Psychology article, she uses a trick of vision where identical circles appear larger or smaller, depending on the context, to investigate differences in perception. She studied this two very different species: guppies and ring doves. In the following guest editorial, she describes how not only how fish and birds perceive their worlds, but also how ecological pressures shape the evolution of perception.
