In complex environments that require fast and accurate responses (e.g. traffic), individuals tend to neglect information and reduce the amount of stimulus properties
they process to a sufficient minimum. Most situations, however, offer more than one of these ‘strategies’ that help to facilitate (but not guarantee) fast and accurate responses.
For example, the ordinary traffic light offers both different colors (red, yellow, green) and different positions (top, middle, bottom) as simple,
correlating properties that cue the correct response (stop, accelerate/slow down, go). Using a variant of the common traffic light,
this experiment examines how consistently participants choose between strategies and whether shifts happen within and/or between subjects.
