The human visual system is very adept at extracting categorical information from complex scenes with only the briefest of exposure. Here we show that information from visual scenes can be processed to the level of identification with formally unattainable, ultra-brief (1 ms) presentations. This brief presentation time is afforded by a new instrument, the light-emitting diode (LED) tachistoscope, in which a liquid crystal display (LCD) is illuminated externally by a brief LED flash after LCD steady-state is reached, such that image onset and offset timing can be precisely controlled. Photographs of animals were presented with or without backgrounds for 1...
Highlights: ► New equipment displays images for 1 ms ► Participants able to identify animals by name with only 1 ms of exposure ► Evidence for superior identification performance for animals presented in isolation than with a background at rapid (1 ms) exposure)
