Abstract
Conservation science and practice commonly draw on the theories and methods of social psychology to explain human cognition, emotion, and behavior germane to biodiversity conservation. We created a systematic map of the cross‐disciplinary conservation science literature, which draws on social psychology concepts and methods in their application broadly described as conservation psychology. Established protocols were used to systematically collect and collate peer‐reviewed research published in an explicit selection of multidisciplinary conservation journals. We sought to catalog the literature, elucidate trends and gaps, and critically reflect on the state of conservation psychology and its research practices that aim to influence conservation outcomes. The volume of publications per year and per decade increased from 1974 to 2016. Although a diversity of research designs and methods was applied, studies disproportionately focused on specific concepts (attitudes and beliefs), locations (North America and Europe), and contexts (terrestrial, rural). Studies also tended to be descriptive, quantitative, and atheoretical in nature. Our findings demonstrate that although conservation psychology has generally become more visible and prominent, it has done so within a limited space and suggest that disciplinary research principles and reporting standards must be more universally adopted by traditional and multidisciplinary conservation journals to raise the floor of empirical research.
