Physiology Of Yawning : Proximate Mechanisms Supporting An Ultimate Function, Melanie Lee Shoup-Knox
Legacy Theses & Dissertations (2009 - 2024)
Recent research suggests that yawning functions to cool the brain during periods of mild hyperthermia. Evidence for this hypothesis is largely behavioral, and includes reports of increased yawning during increases in ambient temperature and times of stress as well as an amelioration of yawning upon nasal breathing and forehead cooling. Little research has been published on the physiological mechanisms supporting a brain cooling function, however. The current set of studies explores human and animal physiological parameters in search of evidence of brain cooling during yawning. In humans, heart rate, skin temperature, and skin conductance findings suggest that yawning involves an …

Disordered Eating And Negative Evaluation Anxiety As Canditates For The Extreme Female Brain Type, Jennifer Ann Bremser
Legacy Theses & Dissertations (2009 - 2024)
Baron-Cohen proposed an inclusive theory of individual differences in cognitive style by creating a taxonomy of brain types that is based on the distinction between empathizing and systemizing. More males, than females, use a `systemizing' cognitive style whereas more females than males use an empathetic cognitive style. Further, he posited that a small percentage of individuals will manifest the pathological "extremes" of sexually differentiated brain-types. In support this theory, people with autism have superior systemizing skills with deficits in empathizing. While Baron-Cohen (2003) also proposed the existence of an `extreme female brain', he did not specify the form it would …
