Congenitally blind and blindfolded sighted children at ages of 6, 8, 10 and 12 years performed a pointing task with their left and right index fingers at an array of three targets on a touch screen to immediate (0 s) and delayed (4 s) instructions. Accuracy was greater for immediate than delayed pointing and there was an effect of delay for the orientation(More)

Congenitally blind and sighted blindfolded children between the ages of 6 and 14 years were tested for hand preference with performance tasks. There were no differences between the groups in direction or degree of hand preference. The degree of handedness increased with age and was essentially linear though the blind seemed to be somewhat less lateralized(More)
The study raises the question of whether guide dogs and pet dogs are expected to differ in response to cues of referential communication given by their owners; especially since guide dogs grow up among sighted humans, and while living with their blind owners, they still have interactions with several sighted people. Guide dogs and pet dogs were required to(More)
Inter- and intra-modal processing was compared with modality-specific forms in two experiments on a group of 40 university students. In Exp. I, the RTs for tactual-to-visual and visual-to-visual processing were compared for 20 subjects, and in Exp. II, the visual-to-tactual and the tactual-to-tactual processing were compared for another group of 20(More)
In three experiments we examined whether memory for object locations in the peri-personal space in the absence of vision is affected by the correspondence between encoding and test either of the body position or of the reference point. In particular, the study focuses on the distinction between different spatial representations, by using a paradigm in which(More)
The present study examined the role of vision and haptics in memory for stimulus objects that vary along the dimension of curvature. Experiment 1 measured haptic-haptic (T-T) and haptic-visual (T-V) discrimination of curvature in a short-term memory paradigm, using 30-second retention intervals containing five different interpolated tasks. Results showed(More)
40 congenitally blind and 40 sighted children were tested for fantasy-reality distinctions of real and imagined objects and the development of concepts of darkness, hidden objects, space, dreams, emotions, facial expressions, size, and height. Analysis indicated that the blind children distinguished between contents of fantasy and reality, although they(More)
The study investigated pointing at memorized targets in reachable space in congenitally blind (CB) and blindfolded sighted (BS) children (6, 8, 10 and 12 years; ten children in each group). The target locations were presented on a sagittal plane by passive positioning of the left index finger. A go signal for matching the target location with the right(More)
The present study was designed to test for differences, if any, in children with impaired hearing compared with a control group of children with normal hearing (7-11-year-olds) in handedness, drawing, categorization, facial recognition, and play. Results indicated age differences in the performance of all the tasks. The children with hearing loss had more(More)
