Abstract:
Maintaining awareness in an ever-changing environment is a difficult task. The observer’s awareness at any given point in time is significantly impacted by the context and the goals of the observer. Despite the best intentions of the observer, there are a number of aspects of visual perception that are likely to cloud the observational accuracy of an individual performing a visual search task. In this experiment, I test the effect of a tool to allocate spatial attention in a movie clip of naturalistic video footage in an environment familiar to the observer. Observational awareness in viewing surveillance footage based on experience and expertise and the potential for technological assessment and improvement of visual search ability is discussed.
