Among the factors that give rise to the ‘Change Blindness’ phenomenon we wanted to investigate the influence of the informativeness of changing elements on change detection time.

Secondarily, we wanted to determine the extent to which each map could predict the performance in a change detection task. We hypothesized that if an observer would include an element in an informativeness map, he would detect the change of that element in a change detection task. On the contrary, if the element was absent from the map, it would go undetected. Our findings show that not all the methods are predictive of the change detection performance and we discuss the implications for scene representation and memory.

Which kind of informativeness map can predict the change detection performance?

Abstract

Among the factors that give rise to the ‘Change Blindness’ phenomenon we wanted to investigate the influence of the informativeness of changing elements on change detection time. In order to generate an informativeness map of a natural scene we developed six different methods derived from other experiments on change blindness (Rensink et al., 1997 Psychological Science 8 368 – 373), scene perception (Antes, 1974 Journal of Experimental Psychology 103 62 – 70) and scene memory [Holšánová, 2001 Picture viewing and picture description (Lund University Cognitive Studies 83)]. Our purpose was to compare such methods and the maps they produced on the basis of their capability to predict the observer’s representation of a natural scene. Secondarily, we wanted to determine the extent to which each map could predict the performance in a change detection task. We hypothesized that if an observer would include an element in an informativeness map, he would detect the change of that element in a change detection task. On the contrary, if the element was absent from the map, it would go undetected. Our findings show that not all the methods are predictive of the change detection performance and we discuss the implications for scene representation and memory.
