Abstract / Description
Individuals who have Attention Deficit/Hyperactivity Disorder (ADHD) experience adverse effects relating to driving; in addition, they experience deficits in scanning ability (Barkely et.al, 1996; Fischer et al., 2007; Munoz et al., 2003; Naja-Raja et al., 2007). The present study examined the effects of ADHD on eye tracking while driving. Ten participants consisting of both ADHD and individuals who do not have ADHD were included in this study. It was hypothesized that individuals who have...
Show moreIndividuals who have Attention Deficit/Hyperactivity Disorder (ADHD) experience adverse effects relating to driving; in addition, they experience deficits in scanning ability (Barkely et.al, 1996; Fischer et al., 2007; Munoz et al., 2003; Naja-Raja et al., 2007). The present study examined the effects of ADHD on eye tracking while driving. Ten participants consisting of both ADHD and individuals who do not have ADHD were included in this study. It was hypothesized that individuals who have ADHD will make more saccadic eye movements and thus shorter fixations than individuals who do not have ADHD. Furthermore, it was hypothesized that despite the fact that individuals who have ADHD will make more saccadic eye movements than individuals without ADHD, those individuals with ADHD will commit more traffic violations including collisions compared to individuals who do not have such a diagnosis. Findings indicated that hypothesis one was not supported by the data, whereas hypothesis two was supported in that ADHD individuals had more collisions and committed more traffic violations than the Control group. Additionally, upon conducting a Chi Square test for independence, a significant difference was found in the spatial distributions of the fixations between the ADHD and Control groups. The findings of this study could help better understand the factors involved in ADHD driving and could be used to train individuals with ADHD to become more aware of their surroundings and driving habits and thus become safer drivers.

Abstract / Description
Stress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration.

Show moreStress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students with normal color vision, depth perception and good visual acuity participated in this study. The overall findings of the study suggest that virtual nature is able to reduce stress and anxiety, generally the more immersive and interactive the better. Moreover, though both the those in the passive VR nature condition and those in the coloring condition reported a reduction in stress, only those in the passive VR nature condition exhibited the physiological changes indicative of stress reduction.

Abstract / Description
Although individuals have limited directed attention capabilities, it has been shown that exposure to natural environments elicit cognitive restoration (i.e. Berman, 2008). It has also been shown that individuals prefer blue and green colors because they are relaxing and prompt happy feelings (Guilford (&) Smith, 1959; Mahnke, 1996; Wexner, 1954). The question however, is what aspects of nature elicit these effects: is it the natural colors, the environmental setting, or both? The present...
Show moreAlthough individuals have limited directed attention capabilities, it has been shown that exposure to natural environments elicit cognitive restoration (i.e. Berman, 2008). It has also been shown that individuals prefer blue and green colors because they are relaxing and prompt happy feelings (Guilford (&) Smith, 1959; Mahnke, 1996; Wexner, 1954). The question however, is what aspects of nature elicit these effects: is it the natural colors, the environmental setting, or both? The present experiment will examine the effects of color (Blue, Green, Black and White, (&) Natural) and environmental setting (Urban, Foliage, (&) Aquatic) on measures of attention, short term memory, and mood. Additionally, this study was designed to replicate the findings of Berman et.al 2008, all while rigorously controlling for the pictorial content of its manipulation. Due to the exploratory nature of this study, no specific hypotheses were made. However, the goal of this research was to (")tease apart(") the effects of color and environment on the restoration of cognitive abilities. One hundred and nineteen non-color blind individuals completed pre and post tests for the State Trait Anxiety Inventory (Form Y-1), Backwards Digit Span, and the Attention Network Task and viewed one of the twelve color/environmental setting picture sets between the pre and posttests. Results of the 2x3x4 Mixed ANOVAs do not support past research which suggests that natural environments are restorative in nature.
