Part II of the book analyzes the aesthetics of haptic form and the art of the blind. The work of blind sculptors is presented and is analyzed. There are a number of illustrations. item. The mechanisms underlying tactile perception of form remain relatively little understood, despite long interest in the topic. This interest extends at least several hundred years, for instance, to Molyneux's question, whether a blind person suddenly given sight would immediately recognize by vision objects previously identified by touch, and to Diderot's letter on the blind (see Morgan, ).Cited by: Object recognition, whether visual or haptic, is impaired in sighted people when objects are rotated between learning and test, relative to an unrotated condition, that is, recognition is view-dependent.

Participants studied pairs of unfamiliar 3-D objects and performed a two-alternative forced-choice identification task, with the learned objects presented both unrotated and rotated ° about the y-.

The present study tests whether age at onset of total blindness and the proportion of life-time without visual experience affect the haptic processing and recognition of tactile pictures in a sample of 20 totally blind adults.

The performance in letter recognition of 21 blind participants was compared with that of 16 age-matched sighted participants in an n-back working memory participants were tested tactually with series of raised letters and Braille characters, and sighted participants tactually with series of raised letters and visually with series of letters presented on a computer by: memory, in a similar way in which a sighted person may mark a graph or table at a point of interest, or leave a note in a margin.

1. Introduction. For obvious reasons, blind people have to rely on other senses than vision. In case of blindness, touch is the most likely sense to replace vision for the acquisition of spatial knowledge of the environment and object properties (Hatwell, a, Hatwell, b).However, as Heller () has pointed out, studying touch in blind persons is subject to several practical by: 9.
