Definición

  • Memory distortion when a picture or a photograph is remembered with a greater extent than actually present, as if the subject was using in his memory a wider angle of view, going as far as inserting new items in the new created space (Intraud & Richardson, 1989).

Nota editorial

  • In Intraub and Richardson's (1989) experiment, participants study 20 photographs, for 15 seconds each, depicting a main object or a group of objects. After the photographs are presented, subjects draw them from memory. The results show that participants tend to draw the objects smaller than in the studied scenes, thus filling the space with new elements that might have been present if the scenes had been presented with a wider viewing angle. Furthermore, a phenomenon of boundary contraction has been observed when the visual scene contains several dispersed objects, whereas boundary extension illusion occurs when the visual scene contains a few central objects (Bainbridge & Baker, 2020).
