An Investigation Of The Neural Components And Saccade Sequences That Enable Direct Navigation Through Virtual Space, Daniel R. Barto

Psychology ETDs

Spatial navigation is a critical behavior for nearly all life forms. The ability to navigate to a destination and to remember how to return to that destination involves numerous brain processes such as perception, attention, memory, learning, proprioception, and distance estimation. The study of spatial navigation, in various organisms and on different sorts of maze-apparatuses, has revealed what is required of the brain and what is required of the environment to enable successful navigation. This dissertation adds to this vast literature by examining the physiological and behavioral components involved in human navigation in a virtual environment.

Social Risks As Costly Trait Signals, Ruth E. Sarafin

Psychology ETDs

Costly signaling theory posits that people will sometimes engage in seemingly irrational behavior to show off attractive qualities about themselves. These behaviors may end in or incur a cost to the actor such that only individuals who are highly fit are able to succeed at the behavior, and therefore behavior success is an honest signal of fitness. Previous research has used costly signaling to explain human physical risk taking behaviors such as rock climbing, but the current study seeks to apply them to social risk taking, such as raising one’s hand in class. Should social risk taking prove to be …
