Hurricane knowledge and interpretation of forecasted error cone and wind potential graphics.

Objective: The purpose was to examine how participants understand, interpret, and make decisions using hurricane forecast graphics.

Design: A four-part online survey was administered. Participants were provided an error cone graphic and one of three experimental potential for damaging winds graphics.

Task-relevant perceptual features can define categories in visual memory too.

Although Konkle, Brady, Alvarez, and Oliva (2010, Journal of Experimental Psychology: General, 139(3), 558) claim that visual long-term memory (VLTM) is organized on underlying conceptual, not perceptual, information, visual memory results from visual search tasks are not well explained by this theory. We hypothesized that when viewing an object, any task-relevant visual information is critical to the organizational structure of VLTM. In two experiments, we examined the organization of VLTM by measuring the amount of retroactive interference created by objects possessing different combinations of task-relevant features.
