Research Interest
The recognition potential (RP) is an electrical response of the brain that is evoked by recognizable images, such as words, pictures, or faces (Rudell, 1991). Meaningless images do not evoke it. The RP peaks about 200 to 300 ms after image onset. Its latency indicates how rapidly an image is perceived. Image quality, word difficulty, and level of reading skill are some factors that affect RP latency. The RP occurs rapidly, well before a behavioral response can be made to a word. Short latency restricts the processes that it reflects to fast acting neural operations. This gives the RP immunity to non-perceptual factors that affect longer latency potentials and behavioral reaction time (RT).
