Driving simulation and cognitive models reveal differences between novice and experienced drivers

06.08.2013
A recent study compared the differences between novice and experienced drivers using a driving simulator and modeled the difference using computational cognitive models.

The method and results provide important cognitive-psychological bases for developing intelligent driver training and driving assistance systems.

The study titled "Modeling the effect of driving experience on lane keeping performance using ACT-R cognitive architecture," authored by Shi Cao, Yulin Qin, and Mowei Shen, has been published on CHINESE SCIENCE BULLETIN, 2013.

Driving experience is a critical human factor of driving safety. In China, there are currently more than 100 million licensed drivers, about one-third of whom are novice drivers with driving experience no more than 3 years. The lack of driving experience is a potential risk factor of accidents.

From the perspective of cognitive psychology, driving is a complex task that requires seamless coordination of multiple cognitive skills including perception, decision, and memory. Analyzing the differences between novice and experienced drivers and studying the mechanisms of driving skill learning are very important and valuable for improving driver training courses and the innovation of training techniques.

Previous studies on driving skills often focused on one cognitive skill but lacked an integrated view of all necessary skills. Considering different aspects of driving skills, Cao et al. used driving simulation to directly measure driving performance (Figure 1), compared the difference between novice and experienced drivers, and quantitatively modeled the difference using computational simulation of human performance.

As the first author Shi Cao said, there were two major challenges of this study: (1) building computerized models that can simulate what happens in a driver's mind in terms of cognitive information processing and (2) figuring out which cognitive factors are different between novice and experienced drivers. Cognitive sciences have provided theories about the architecture of human mind, that is, the mind is a complex integration of different functional modules such as visual encoding, memory, and decision modules. Cognitive-architecture-based models integrate all aspects of cognition to explain how the mind works. Researchers are using such models to support the design and evaluation of complex human-machine systems.

The results from this study showed that the experienced drivers had better control of vehicle lane position than the novice drivers, which was simulated by setting a closer visual attention point for the novice drivers in the cognitive models. It indicates that novice drivers' poorer control of lane position may be due to not utilizing road information farther enough.

The authors believe that there will be more and more simulation and intelligent systems that can be used to facilitate driver training and improve driving safety. The driving simulator used in this study can also run on common personal computers that most people have today. After some configuration of road and environment scenarios, such simulators can be used to train new drivers under simulated emergencies such as tire explosion and skid. Computational models will be able to track the development of skills and intelligently determine the contents and progress of training. The authors are planning to develop such training systems in the next phase of research.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
