Blood Alcohol Levels

Two experiments were performed to determine the effects of alcohol and marihuana on visual scanning patterns in a simulated driving situation. In the first experiment 27 male heavy drinkers were divided into three groups of nine, defined by three blood alcohol levels produced by alcohol treatment: 0.0%, 0.075%, and 0.15% BAC's. Significant changes in visual search behavior including increased dwell duration, decreased dwell frequency, and increased pursuit duration and frequency were found under alcohol. In the second experiment, 10 male social users of marihuana were tested under both 0 mcg and 200 mcg tetrahydrocannabinol per kilogram bodyweight. Marihuana was found to have no effect on visual search behavior. The results are related to previous studies of alcohol and marihuana effects on information processing.

AbstractVisual inspection of luggage using X-ray technology at airports is a time-sensitive task that is often supported by automated systems to increase performance and reduce workload. The present study evaluated how time pressure and automation support influence visual search behavior and performance in a simulated luggage screening task. Moreover, we also investigated how target expectancy (i.e., targets appearing in a target-often location or not) influenced performance and visual search behavior. We used a paradigm where participants used the mouse to uncover a portion of the screen which allowed us to track how much of the stimulus participants uncovered prior to their decision. Participants were randomly assigned to either a high (5-s time per trial) or a low (10-s time per trial) time-pressure condition. In half of the trials, participants were supported by an automated diagnostic aid (85% reliability) in deciding whether a threat item was present. Moreover, within each half, in target-present trials, targets appeared in a predictable location (i.e., 70% of targets appeared in the same quadrant of the image) to investigate effects of target expectancy. The results revealed better detection performance with low time pressure and faster response times with high time pressure. There was an overall negative effect of automation support because the automation was only moderately reliable. Participants also uncovered a smaller amount of the stimulus under high time pressure in target-absent trials. Target expectancy of target location improved accuracy, speed, and the amount of uncovered space needed for the search.Significance Statement Luggage screening is a safety–critical real-world visual search task which often has to be done under time pressure. The present research found that time pressure compromises performance and increases the risk to miss critical items even with automation support. Moreover, even highly reliable automated support may not improve performance if it does not exceed the manual capabilities of the human screener. Lastly, the present research also showed that heuristic search strategies (e.g., areas where targets appear more often) seem to guide attention also in luggage screening.

On The Road

This paper reports on two studies that examined the relationship between field dependence and on-the-road visual search behavior. In the first study, concerned with eye movements in curve negotiation, it was found that field-dependent subjects have a less effective visual search pattern. In the second study, young and aged drivers were compared on several information processing tasks and on their ability to maintain their eyes closed part of the time while driving. Of the various information processing tasks, only field dependence and visual search time correlated significantly with the mean time the drivers needed to maintain their eyes open while driving, Together the two studies indicate that field dependent subjects require more time to process the available visual information and are less effective in their visual search pattern.

Static Conditions

The perception of road curves by car drivers was studied in a simulated driving situation. The purpose was to investigate how planting structures along the road would affect the distance at which the curve was clearly perceived by novices and by experienced subjects, respectively. Subjects rated the clarity of the curve percept in different situations on a nominal scale from 1 to 7. Estimations were made under static conditions at the distances 0 m, 100 m, and 200 m before the beginning of the curve. The critical point for a clear percept was found to be at 100 m for novices and at 200 m for experienced drivers. The planting conditions made no difference.
