pareidolia

La apofenia es la experiencia consistente en ver patrones, conexiones o ambos en sucesos aleatorios o datos sin sentido. El término fue acuñado en 1959 por Klaus Conrad, quien lo definió como «visión sin motivos de conexiones» acompañada de «experiencias concretas de dar sentido anormalmente a lo que no lo tiene».

apofenia, fenómeno psicológico limítrofe entre la psicosis y la creatividad, que consiste en la unión cerebral de dos elementos sin un aparente patrón común.

Synesthesia is a neurologically-based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. In one common form of synesthesia, known as grapheme → color synesthesia or color-graphemic synesthesia, letters or numbers are perceived as inherently colored, while in ordinal linguistic personification, numbers, days of the week and months of the year evoke personalities. In spatial-sequence, or number form synesthesia, numbers, months of the year, and/or days of the week elicit precise locations in space (for example, 1980 may be "farther away" than 1990), or may have a (three-dimensional) view of a year as a map (clockwise or counterclockwise). Yet another recently identified type, visual motion → sound synesthesia, involves hearing sounds in response to visual motion and flicker.
