Tilt aftereffect due to adaptation to natural stimuli.

摘要: Abstract The human visual system continuously adjusts to the current environment. To investigate these adjustments, biases in observers’ perceptions owing changes environment are measured (visual aftereffects). Typically, stimuli used synthetic and composed of oriented patterns such as lines or gratings. These known activate individual neurons cortex, but cover only a small subset actual stimulations. overcome this drawback, recent research has focused on that mimic several aspects natural stimulation. However, aftereffects stimulation per-se remain largely unexplored. Here, we interleaved presentations unmodified image adaptors, selected according criteria favoring content at particular orientation, with targets test perceived orientation. This allowed us measure change namely tilt aftereffect (TAE), which resulted from repeated presentations. Results show close standard TAE adaptor durations around 500 ms, is reduced longer Importantly, our method can be generalized other by selecting images differently.
