Description
Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Description
Northeastern Arizona has experienced a recent increase in helium extraction activity. This qualitative case study articulates and explores various sociotechnical imaginaries – or, collectively produced social justifications for technological decisions and systems – that inform this new stage of underground helium extraction. Leveraging two years of interviews, document analysis, and participant observations to understand and interrogate the political and cultural origins of perceptions around helium extraction, I examined how these imaginaries and associated power dynamics influenced communication within and between stakeholder groups. In order to mitigate the power differentials between stakeholder groups, and put these imaginaries in conversation with each other, I led the development of a series of short videos that explain controversial technoscientific concepts from this research. These videos were produced in continuous collaboration with multiple disparate stakeholders, including activists, regulators, and industry members, in order to create a space for a productive conversation and reflection to explore tensions between conflicting points of view between stakeholders. This iterative work used the imaginaries of helium extraction in Arizona to produce a space for collective deliberation that can result in negotiated shared knowledge through brokered dialogue amongst these disparate groups and their competing visions of Arizona’s helium futures.
