Abstract |
The present study investigates the effect stimulus-response binding processes in action control have on drivers' behavior. Warning displays of driver assistance systems usually consist of several features, even those that may have no particular meaning for a currently to-be-executed response. Yet, research on distractor processing has shown that all features in a selection situation are integrated with responses and thereby can later on directly influence behavior due to feature-based retrieval of responses (which can be compatible or incompatible in the current situation). In four experiments we investigated the influence of ignored display-features on responses to local danger warnings. Participants responded manually (Experiment 1, N = 30) to the display colors and ignored additional icons (depicting a particular danger) on the displays. We approached responding in a driving and braking situation by using foot pedals for the responses (Experiment 2, N = 29), using a go/no-go task (as to imitate braking vs. no braking; Experiment 3, N = 60), and a real driving situation (Experiment 4, N = 25). We observed clear effects of feature-based response retrieval on performance when the features were relatively complex, while participants reacted via foot pedals as well as while driving a car. The repetition of an ignored feature facilitated behavior if the response also repeated, but hampered different responses. It is concluded that the possible influence of distractor-response binding on drivers' responses should be taken into account for the design of local danger warnings in driver assistance systems. |
