||A flashlight enables us to see a part of the world in the dark.
Our application 'Flashlight' uses this metaphor and shows the participant (and later the researcher in the analysis) a part of a stimulus. When the participant moves the mouse to inspect a stimulus on his computer, Flashlight uncovers the area underneath the mouse cursor while recording the mouse position.
Flashlight offers a cost effective and rapid means to collect data on how long and how often a participant attends to different areas of visual stimuli. These real time data are of central importance to understanding psychological processes and can facilitate opening the black box of human cognition.
