The present study aimed the adaptation of the Driving Log, a questionnaire that assesses aggressive and risky driving behaviors in a day by day basis, with 395 Spanish participants. Confirmatory factor analysis showed that the questionnaire fitted properly in two correlated factors, labeled as Risky Driving and Aggressive Driving. Subsequent analyses showed that the number of drives is significantly associated to Risky Driving, while the number of occasions in which anger is experimented correlated with Risky Driving as well as Aggressive Driving. Other findings suggest that men behave in a more risky and aggressive mannerthan women. Young people follow this same tendency in comparison to their elders. / El presente estudio tuvo como objetivo la adaptación del Driving Log, un cuestionario que valora los comportamientos agresivos y arriesgados al volante, en una muestra española de 395 personas. El análisis factorial confirmatorio mostró que el cuestionario ajustaba satisfactoriamente en dos factores, etiquetados como Conducción Arriesgada y Conducción Agresiva. Los análisis posteriores mostraron que el número de trayectos realizados se asoció significativamente a la Conducción Arriesgada, mientras que el número de veces en que se experimentó ira lo hizo tanto con la Conducción Arriesgada como con la Conducción Agresiva. Igualmente, se vio que los hombres se comportaban de forma más arriesgada y agresiva que las mujeres, y que los jóvenes lo hacían en mayor grado que los mayores.

This study investigates factors that may be related to dependency on driving and decisions to continue or ceased riving in older age. Some older drivers may be unsafe to drive (Drachman & Swearer, 1993), but are unwilling to cease, this can result in referrals to mental health services. The potential influence of attitudes towards driving on driving behaviour has been highlighted (O'Neill, 1996) but as yet has not been fully investigated. A questionnaire was developed, based on the Theory of Planned Behaviour, to elicit factors which might predict older drivers' intentions to drive more or less often. Reliability was demonstrated for the questionnaire, which was completed by 99 older drivers. The results indicated that the majority of older drivers used their car frequently. Two components of the Theory of Planned Behaviour were demonstrated to predict 73% of the variance in driving behaviour, namely, perceived behavioural control and attitude towards driving. Those drivers who perceived more positive outcomes for driving and less negative outcomes were likely to intend driving more often. Also those drivers with higher levels of perceived behavioural control were likely to intend to drive more often. A self-report measure of actual driving behaviour two to three months later, suggested that behavioural intention was highly related to subsequent driving behaviour. Methodological issues, future research and clinical implications of the findings are discussed. In particular, interventions based on attitude change and problem solving to decrease perceived dependency on the car, may facilitate the process of giving up driving.

abstract: ABSTRACT Research studies have demonstrated that stereotypes can elicit a priming response. An experiment was conducted to test the effects of priming elderly and young stereotypes on driving behavior. Participants drove in a driving simulator while navigating through two driving routes. Participants were guided by a neutral voice similar to "Siri" that informed them where to turn. Each route primed the participants with names that were deemed "old" or "young" as determined by a survey. The experiment yielded slower driving speeds in the elderly condition than in the young consistent with previous research regarding elderly stereotypes (Bargh et al, 1996; Branaghan and Gray, 2010; Taylor, 2010; Foster, 2012). These findings extend research on priming and behaviors elicited by participants in a simulated driving environment. / Dissertation/Thesis / M.S. Applied Psychology 2014

M.Ing. / The induction machine is being widely implemented in motor control systems. Frequently not all the parameters of a system, which consists of an induction machine, an inverter, a load and a controller, are known. As the response of an induction machine is very sensitive to changes in these parameters, it is important to be able to design a control system that is independent of any parameter changes. In the past years, many control techniques have been developed for speed control of machine drives. The use of intelligent controllers has also recently been proposed to improve the response of the induction machine drive. With a fuzzy controller, we will try to eliminate as much as possible the effects of parameter variations that influence the response of the drive system. Since the fuzzy controller design is independent of the dynamic drive system model, the performance of the fuzzy controller is insensitive to any parameter changes. The fuzzy controller replaces the proportional- and integral controller (PI-controller) to determine the slip in a slip controller. The system for which the fuzzy controller is being investigated for implementation, is a battery operated wheelchair using two three phase cage rotor induction machines. These small; low voltage machines show strong parameter variations, making conventional control difficult. The fuzzy logic controller was investigated and the response compared with that of the PI-controller. The results indicated that at high rotor speeds the response of the fuzzy control strategy was favourable, but at low speeds ineffective. By modifying the fuzzy control strategy the rotor speed response can be optimised over the total speed zone.

This thesis reports three experiments investigating how age-related declines in visual motion processing affect older drivers’ ability to drive safely. In particular, these experiments assess the efficacy of: 1) A test of motion sensitivity, the Peripheral Motion Contrast Threshold (PMCT) test, which evaluates ones’ contrast threshold for detecting motion in the periphery, and 2) the 3D multiple-object tracking test (3D MOT), which evaluates the maximum stimulus speed at which one can maintain visual attention on several objects moving in three dimensions. Two versions of the PMCT test—the PMCT-10 and the shorter PMCT-2—were employed. Driving safety was measured via a high fidelity driving simulator, in addition to several self-report measures and archival data. Study 1 showed that PMCT-2 and PMCT-10 thresholds were associated with number of crashes in the simulator and other indices of unsafe driving. Study 2 examined whether the PMCT-2 could predict older driver performance during a different set of simulated driving scenarios, and whether it was associated retrospectively with real world crash rates. PMCT-2 results were significantly correlated with simulated crash risk. Moreover, Study 2 provided the first evidence that PMCT scores are associated with real-world crash, albeit in a small retrospective sample. Study 3 examined the relationship between results from both the PMCT-2 and 3D MOT tests and simulated driving. Multiple object tracking has previously been associated with older drivers' performance. Results showed a strong relationship in our sample between crash rates and 3D MOT results. However, we failed to replicate the results showing a relationship between PMCT and crash occurrence. This may have been due to high rates of subject attrition due to simulator sickness, which resulted in a small final sample. Overall, findings from the three studies demonstrate that results from PMCT and 3D MOT are associated with older drivers’ performance measures, such as crash rates, dangerous lane deviations, and speeding. These findings support visual motion processing measures as viable candidates for inclusion in a multi-domain assessment of older drivers’ fitness to drive.
