Results indicated normative relationships between looming ability and age, looming ability and driving violation records, and age and driving violation records. Findings also confirmed the validity and reliability of the measurements taken with the device. In conclusion, this device may be useful for identifying drivers at risk for rear-end collisions, developing effective training interventions, and creating fair and valid driver licensing tests.

A Portable Device for Dynamic Visual Acuity

DVA is sensitive to alcohol and aging. In two within-subject, repeated-measures designs, a laser DVA device was compared to the traditional device. Both tasks were administered to two groups: Group I received graded stimuli at 60, 75 & 90 degrees per second (dps); Group II at 60, 90 & 120 dps. Testing involved different target sizes, velocities, type of target, and time course changes within a session. Findings: 1) retest reliabilities of the two DVA devices were comparable and higher with the laser; 2) average correlations between the devices were r = 0.62 ( p < .01) and r = 0.65 ( p < .01) for Group I and II respectively. In spite of the known differences in implementation, the laser device can be developed to measure the same construct as the more traditional DVA device, and the laser is considerably more flexible.

Visually-induced motion sickness: An experimental investigation

Forty adults between the ages of 18 and 47 participated in this experiment. In the control condition, the participants were required to complete a single self-propelled rotation simulation (SRS) trial, and then use a visually coupled head mounted virtual reality (VR) device plus exposure to an optokinetic rotating drum (OKN) device. In the experimental condition, all the participants took part in a five-session study in which they were exposed to five trials of the SRS and to the VE and OKN rotating drum. Immediately following each task, all participants were required to rate their level of dizziness. The results showed a significant main effect of adaptation training on both the VR and OKN rotating drum as reported by the dizziness ratings. These findings indicate that the difference in dizziness rates was markedly higher among the control group than the experimental group.

Forty participants were randomly assigned to either a control (no training with SRS) or experimental (4-day training with SRS) condition. The results indicated that the experimental group who had prior training with SRS reported lower DLQ scores (Mean=2.09) than the control group participants (Mean=4.09) following VE exposure. Similarly, the experimental group who had prior training with SRS reported lower DLQ scores (Mean=1.95) than the control group participants (Mean=3.68) following OKN exposure. With regard to SSQ scores, the experimental group who had prior training with SRS reported significantly lower SSQ scores following the day 5 SRS exposure (Mean= 11.49) than the control group (Mean=1.60). Furthermore, the experimental group who had prior training with SRS reported significantly lower SSQ scores (Mean=11.75) than the control group participants (Mean=22.71) following VE exposure.

Forty participants were randomly assigned to either an OKN or a VE training condition. In the OKN condition, participants trained on the OKN device for four days, and were then tested on the VE and OKN devices on day five. In the VE condition however, they trained on the VE device for four days and were then tested on the VE and OKN devices on day five. The results indicated a 14.6% drop in DLQ scores and a 48.12% drop in SSQ scores for the OKN group. Similarly, a 21.28% drop in DLQ scores and a 23.64% drop in SSQ scores was obtained for the VE group. These results suggest that transfer of training occurred for both VE and OKN environments. Finally, these patterns of results are consistent and point to the importance of specific pre-adaptation training environments that would promote transfer to other motion sickness platforms. These findings have implications for training on different platforms.

The goal of this case study was to assess the risk of injuries and accidents from conducting various tasks in the restaurant, specifically carrying/lifting, table management, and polishing silverware. The nine participants were servers at a local country club restaurant. Physical workload was measured by a scale of physical exertion. Cognitive workload was assessed, as well as cumulative trauma disorder risk. Overall results show that there is sufficient risk in some of the tasks to warrant concern. Specific results are discussed, as well as recommendations for improved safety.

The program was to include a fully automated computer-based instructional system as well as simulator-based driver-training scenarios. This first phase of the research was to focus on concept feasibility and prototype development. The methodology that the authors used to achieve the aforementioned objective included conducting a thorough assessment of the Driver Training Program of the Orange County Public School System (OCPS). Based on that assessment, a computer-based driver training system was developed, and a scenario for a high fidelity driving simulator for training and evaluation was created. Lastly, preliminary validation of the computer based training modules was conducted.

Driving, aging, and temporal factors in vision: an exploratory study

Driving places major demands on human perceptual, cognitive, and motor capabilities and so age-related declines in these capabilities negatively affect driving performance. Given that driving largely involves the processing of visual information that changes rapidly over time, agerelated changes in dynamic visual abilities are likely to have some impact on driving performance. Driving anD age-relateD visual Declines With age, a number of changes occur in the human eye that result in the visual system operating less efficiently. One of the major declines in vision due to aging involves visual acuity. Contrast sensitivity also declines with age. Furthermore, older adults tend to be more affected by glare and have a longer recovery time after having been subjected to it.

Three major groups of participants employed in the proposed research. The younger group range from 19 to 34 years of age, the middle-age group range from 35 to 59 years, and the older group were 60 years and above. The research for first phase of the study was carried out in the Visual Performance Laboratory in the Department of Psychology at the University of Central Florida. It consisted of determining various perceptual and cognitive measures. In addition, tests assessing neurological status were carried out in the FASST Laboratory at the same time. The last phase or the simulation phase of the study was also carried out in the Visual Performance Laboratory using a low fidelity simulation of the driving task. In general, it was found that tests such as the UFOV, the Digit Symbol, the Block Design, the Trails B, and Contrast Sensitivity seem to be better able to predict driving performance on the low fidelity simulation task compared to some of the other tests. It was observed that younger drivers had more collisions/crashes than middle-aged drivers, and they had more collisions/crashes than older drivers. Older drivers were less likely to exceed speed limits and younger drivers. It was also found that the various measures of UFOV (useful-field-of-view) increased with the age of the participant. Thus, younger drivers were found to be responsible for more collisions/crashes and lack of obeying of speed limits than older drivers. However, changes in older drivers might best be measured using various neurological measures and the UFOV.

Effects of Alcohol, Aging, and Sleep Loss on Temporal Factors in Vision

Thus a driver must very rapidly and continuously shift attention to interact with changing elements in a dynamic visual scene. Typically, however, visual tests used for certification and renewal of driver licenses ignore the transient nature of seeing and use visual test stimuli presented for extended duration under static conditions. Furthermore, recent literature implies that disruption of visual performance due to alcohol ingestion and other stressors is greater for tests involving transient visual capabilities than for tests of static visual performance such as high and low contrast acuity. We believe that how these temporal visual factors are modified by alcohol and aging, and even how many temporal factors there might be, have not been investigated thoroughly. While considerable literature exists on temporal and spatio-temporal processing, transportable, standardized tests of such abilities have not been generally available. To this end, a portable computerized test battery of six temporal acuity tests (saccadic accuracy, simultaneity, strobe, phi phenomenon, critical flicker frequency, and masking) was administered to participants in a series of interlocking studies. Reliabilities, effects of practice, and predictive validities are available for alcohol, aging, and sleep loss effects. Factor analyses from two of these studies (N=58 and N=45) suggested a consistent two-factor dimensionality for the battery. The application of these tests for driving safety is discussed and current plans for relating performance to simulated and real driving performance (i.e. accidents) is reported.(A) For the covering abstract of the conference, see ITRD Abstract No. E201067.

Perceptual measures included far and near point acuity, stereopsis, a measure of lateral and vertical phoria, color vision; and spatial contrast sensitivity. Cognitive functioning was examined using the Useful-Field-of-View (UFOV) Test. In addition, each driver completed a Driving Habits Questionnaire (DHQ). Although older drivers tended to have fewer collisions and exhibited better adherence to speed limits in a simulated driving task than did younger drivers, older drivers appear to be at a greater risk of having a collision, resulting from degraded divided and selective attention compared to the younger drivers.

Items presented were generated by a human speaker or by a text-tospeech computer synthesizer. Results were consistent with the idea that the comprehension of synthetic speech imposes increased resource demands on the short term memory system. Older subjects performed significantly more poorly than younger subjects, and both groups performed more poorly with synthetic than with human speech. Findings suggest that short term memory demands imposed by the processing of synthetic speech should be investiqated further, particularly regarding response systems in devices for

Given the psychological complexity of experienced trait loneliness and its potential to reduce perceived social presence, an experiment using a social robot was conducted to examine how trait loneliness impacted perceived social co-presence, psychobehavioral interdependence, and subjective mutual presence in social robot interactions. Furthermore, we explored whether these effects differed from human-to-human interactions. Although trait loneliness only affected third order subjective copresence among the three social presence dimensions, individuals with higher trait loneliness were more likely to accept the robot as a social companion.

This can be especially observed in food distribution systems within nursing homes. While nursing homes have various practices and structures that affect a resident’s physical and mental health, the process of food distribution considerably relates to issues of autonomy. Because loss of independence may lead to increased rates of elderly loneliness and depression, mealtimes and the process of food distribution are an integral part of improving a resident’s quality of life and encouraging socialization and self-sufficiency. Moreover, developing patient experiences within food distribution systems, whether centralized or decentralized, will likely improve resident’s autonomy and self-efficacy, reduce frustration, and enhance their overall mental and physical health.
