	Abstract

Public opinion research on nanotechnology has primarily focused on judgments of abstract risks and benefits, rather than attitudes toward specific applications. This approach will be less useful as nanotechnology morphs from a scientific breakthrough into an enabling technology whose impacts on people’s lives come in the form of concrete applications in specific areas. This study examines the mental connections or associations US citizens have with nanotechnology (e.g. the extent to which people associate nanotechnology with the medical field, the military, consumer products, etc.), and how these associations moderate the influences of risk and benefit perceptions on attitudes toward nanotechnology. Our results suggest that the assumption that risk perceptions shape overall attitudes toward emerging technologies is simplistic. Rather, individuals who associate nanotech with particular areas of application, such as the medical field, take risk perceptions much more into account when forming attitudes than respondents who do not make these mental connections.
