When places are explored without vision, observers go from temporally sequenced, circuitous inputs available along walks to knowledge of spatial structure (i.e., straight-line distances and directions characterizing the simultaneous arrangement of the objects passed along the way). Studies show that a life history of vision helps develop nonvisual sensitivity, but they are unspecific on the formative experiences or the underlying processes. This study compared judgments of straight-line distances and directions among landmarks in a familiar area of town by partially sighted persons who varied in types and ages of visual impairment. Those with early childhood loss of broad-field vision and those blind from birth performed significantly worse than those with early or late acuity loss and those with late field loss. Broad-field visual experience facilitates perceptual development by providing a basis for proprioceptive and efferent information from locomotion against distances and directions relative to the surrounding environment. Differences in the perception of walking, in turn, cause the observed differences in sensitivity to spatial structure.
Inclusive higher education is a path to protect the educational rights of university students with disabilities. University teachers’ attitudes toward students with disabilities, and towards their inclusion in universities, are a key factor that will affect the development of inclusive higher education. This study used a questionnaire to explore an overall perspective of how university teachers in China view inclusive higher education from emotional, cognitional and conative aspects. Their responses suggest that university teachers in China have positive emotion and cognition toward the rights of students with disabilities to receive higher education; the teachers do, however, appear to lack motivation, relevant knowledge, skills, and effective strategies to cope with the students’ special needs. This suggests that effective implementation of inclusive higher education must be supported by an effective service center for those who have disabilities, a support network of professionals, and an administrative support system for teachers and students.
Teaching blind, preschool-age children to use a long cane in travel is a relatively new concept in orientation and mobility. This article examines this issue and discusses potential advantages of early cane use, challenging traditional arguments against early introduction of the cane. Instructional considerations and optional strategies for teaching use of the cane to preschoolers are included.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
