Introduction
Pareidolia refers to the illusory perception of meaningful shapes from random or ambiguous stimuli. In the visual domain, individuals often report seeing images of faces, animals, or objects in random scenes, such as the Man in the Moon, the Moon Rabbit, and Jesus in a toastSpatio-temporal features of the human face perception system have been extensively investigated with neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI) and electro/magneto-encephalography (EEG/MEG)Albeit the neuroimaging evidence reviewed above provides information about the localization and timing of face pareidolia, there is so far a lack of The study of illusory face perception is rendered complex by the literature inconsistencies on the concept of face pareidolia and its operationalization. Indeed, it has been used to refer to faces seen in face-like patterns in the environment, as well as in meaningless noise patterns. Accordingly, previous studies investigated pareidolia with pure noise images (i.e., in which no face is present)In line with previously reported tACS effects on both accuracy and RTs (e.g., visual detection tasks)
