RESUMO
This study was designed to empirically examine the effects of iPod device and text-messaging activities on driver distraction. Sixty participants were asked to perform a driving simulation task while searching for songs using an iPod device or text messaging. Driving errors as measured by lane deviations were recorded and analyzed as a function of the distracters. Physiological measures (EEG) were also recorded during the driving phases in order to measure participant levels of cortical arousal. It was hypothesized that iPod use and text messaging would result in a profound effect on driving ability. The results showed a significant effect of iPod use and text-messaging on driving performance. Increased numbers of driving errors were recorded during the iPod and text-messaging phases than the pre- and post-allocation phases. Higher levels of Theta activity were also observed during the iPod and Text-messaging phase than the pre- and post-allocation phases. Implications for in-vehicle systems design, training, and safety are also discussed.

The objective of this study was to develop a variety of sensory stimulation products for the behavioral intervention of patients with Alzheimer's type dementia. Many caregivers have relied on physical and chemical restraints as the primary method of patient intervention due to the lack of appropriate dementia management products. This significantly lowers the sufferer's quality of care and life. As the age group most susceptible to Alzheimer's disease (65 and older) is the fastest growing segment of our society, an appropriate care solution must be sought. The specific aim of this study was to develop products that are sensory satisfying for the Alzheimer's patient that exhibits self-stimulatory wandering behavior. Sensory satisfying objects for product development would be determined through structured observations of self-stimulatory wanderers in an institutionalized setting. Variations of product design and mounting would be pursued in order to develop products that are not only safe and effective for patient use, but are easy for the caregiver to implement and maintain. Such products would have widespread commercial application in both the institutional and private care settings such as nursing homes, adult day care facilities, Alzheimer's care facilities, convalescent homes, mental health institutions, and assisted-living facilities.

Comfort ratings and response times for changes in the experienced level of comfort were examined in 20 subjects using the NASA Flight Research Center's Jetstar aircraft modified to carry the GPAS system (General Purpose Airborne Simulator). Data were obtained for each of the subjects during two runs of 10 1-min. flight segments. In general, as the magnitude of aircraft motion increased in either the vertical or transverse (lateral) directions, there was an increase in feelings of discomfort and a decrease in response times to those changes. These results suggest parallels between the large body of laboratory data on human reaction time and that collected in this field study on response times to changes in ride comfort.
