| contents | Pattern Perception and Pictures for the Blind Morton A. Heller Melissa McCarthy Ashley Clark Psicología This article reviews recent research on perception of tangible pictures insighted and blind people. Haptic picture naming accuracy is dependent uponfamiliarity and access to semantic memory, just as in visual recognition.Performance is high when haptic picture recognition tasks do not dependupon semantic memory. Viewpoint matters for the ease or difficulty ofinterpreting haptic pictures of solid objects. Top views were easiest forsighted and blind persons when geometrical solids had constant crosssectionsin the vertical axis. The presence or absence of viewpoint effectsdepends upon the nature of the solids that are represented. Congenitallyblind people do not spontaneously produce perspective drawings, but recentdata suggests that depictions including linear perspective can be understoodafter minimal experience. The results suggest that two-dimensionalconfigurations are not necessarily problematic for touch. 2005 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16926112 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.1 Vol.26 |
