Visual Illusion Susceptibility In Dogs Using The Ebbinghaus-Titchener Illusion In A Spontaneous Choice Task, Nicolette Becker
Visual Illusion Susceptibility In Dogs Using The Ebbinghaus-Titchener Illusion In A Spontaneous Choice Task, Nicolette Becker
Theses and Dissertations
In recent years, dogs have been a popular test subject when studying visual illusion susceptibility. Multiple studies have investigated whether animals perceive illusions as humans do, but few studies have evaluated dogs’ perception of illusory stimuli. In this thesis, we studied if dogs are visually susceptible to the Ebbinghaus-Titchener illusion when presented in a spontaneous choice task. Subjects were presented two visual images on a board, which had bologna pieces embedded in the stimuli. In control trials, two different sized bologna pieces were placed in the center of the images. In these control conditions, dogs were expected to choose the …
The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe
Masters Theses, 2010-2019
The relation between chronic sleep restriction and performance on the Psychomotor Vigilance Task (PVT) have been well documented in the human literature, with chronic sleep restriction as little as 7 hours per night resulting in significant impairment in sustained attention performance measured via the PVT. Recently, an analogous version of the human PVT has been developed for use with rodent models (rPVT). Recent studies have measured the effects of sleep restriction on rPVT performance, citing similar results found in the human literature. However, few studies to date have directly examined the role of adenosine accumulation during sleep deprivation in producing …
