Perky effect

Noun The phenomenon whereby sensory input, or perceptions, can be mistaken for a mental image when perceptual processes and mental imagery interfere with each other. en 2007 Monica Gonzalez-Marquez Methods in Cognitive Linguistics 286 If Perky effects like these are indeed indicative of visual imagery making use of the same neural resources recruited for actual vision, then they can naturally be extended to language processing.
