This article presents a model for the motion of a long-cane executing the touch technique and presents formulas for the projected length of a cane adequate to protect an individual with blindness against wall-type and pole-type hazards. The paper concludes that the long-cane should reach from the floor to the user's armpit. (JDD)

Explores children's conceptions of burning through observation and discussion of a number of challenging phenomenon. Finds that children's conceptions are both specific and contextually based. (Author/CCM)

Research has suggested that perception and action are independent (see M. A. Goodale & A. Haffenden, 1998). The authors used the Ebbinghaus illusion to test this hypothesis in 2 experiments. Verbal reports of perceived size were compared with maximum grip aperture during grasping (Experiment 1) and manual reports of perceived size (Experiment 2).…

This study of the haptic exploratory strategies used by nine children with visual impairments and additional disabilities when interacting with portable and freely manipulable objects found that a broader approach to assessment and analysis is required than is used with typically developing children. An "adaptive-tasks" approach is proposed as a…

In tactile learning, sucrose is the unconditioned stimulus and reward, which is usually applied to the antenna to elicit proboscis extension and which the bee can drink when it is subsequently applied to the extended proboscis. The conditioned stimulus is a tactile object that the bee can scan with its antennae. In this paper we describe the…

This laboratory experiment utilizes the characteristic aromas of some functional groups to exploit the sense of smell as a discriminating tool in an organic qualitative analysis scheme. Students differentiate a variety of compounds by their aromas and based on their olfactory classification identify an unknown functional group. Students then…

This study evaluated the effectiveness of fine motor physical activity with tactile stimulation during two conditions of math problem solving, visual and auditory. Eight 4th and 5th grade students with attention problems participated. Using an alternating treatments design, students solved as many math story problems as they could, presented on…

Viewing a threatening stimulus can bias visual attention toward that location. Such effects have typically been investigated only in the visual modality, despite the fact that many threatening stimuli are most dangerous when close to or in contact with the body. Recent multisensory research indicates that a neutral visual stimulus, such as a light…

Two experiments were conducted with 80 college students to examine factors associated with the crossmodal facilitation of learning Braille symbols when the visual modality is utilized. In Experiment 1 subjects using the haptic mode were informed of both the structure of the braille cell and the range of dot numerosity of the symbols to be…

The paper reports on a study of Braille learning in which subjects (N=96) were provided with information about the structure of the Braille alphabet and expressly instructed to use that information during learning. A previous experiment had found that merely providing subjects with information about Braille alphabet structure had no effect on…

Forty-eight blind children, able to cope with set sizes of two and three, four, five or six serial items were tested on probed recall of Braille letters they could either name or discriminate. (Editor/RK)

Paper presented at the International Seminar on Experimental Research in Music Education (University of Reading, Reading, England, July 9-16, 1968).

A STUDY OF PERCEPTION USED A SAMPLE OF 325 CEREBRAL PALSIED CHILDREN (211 WERE SPASTIC, 114 WERE ATHETOID) AND 110 NORMAL CHILDREN. ALL CHILDREN WERE BETWEEN SIX AND 16 YEARS OF AGE AND OF NORMAL INTELLIGENCE. TO INVESTIGATE PERCEPTUAL DISTURBANCES, SIX TESTS WERE ADMINISTERED--THE TACTUAL MOTOR TEST, THE SYRACUSE VISUAL FIGURE BACKGROUND TEST…

GRADES OR AGES: Four-, five-, and six-year olds. SUBJECT MATTER: Sensory experiences, including tactile, auditory, and visual. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into three sections, one for each of the above sensory areas. Each section lists materials and describes activities; illustrations are interspersed. The guide is…
