Congenitally Blind

The structure of spatial representation in congenitally and adventitiously blind 11-year-old children was examined by means of pointing, map-drawing, and spatial reasoning on two simple routes over repeated trials. Although all the children learned how to travel each route successfully after only one trial, three out of four of the congenitally blind children showed a complete lack of spatial understanding, as evinced by “egocentric” or “self-referent” spatial coding strategies, whereas all the adventitiously blind subjects exhibited appropriate externally referent spatial strategies compatible with convential two-dimensional maps. The role of previous visual experience in the encoding and decoding of spatial material in memory is discussed.

Blind Individuals

This article discusses the effect on congenitally blind children of three types of parents: those who are over-protective, those who push the child toward independence too soon, and those who are “good enough.” The authors focus on how the three styles of parenting affect the blind child's ability to give and receive and develop a sense of competence. These effects are discussed in the context of the ego ideal. The authors also examine the depressive core that is often the result of the blind child's inability to live up to the dictates of the ego ideal. Finally, they suggest a fourth style of parenting that would prepare blind children better for the problems they will encounter in the sighted world.

Visual Reference

Blindfold normal, blindfold autistic and congenitally blind children made reproduction location and distance estimates of an arm movement. For each task they first experienced a standard vertical movement of a predetermined extent. In the test tasks which followed, they either reproduced the movement exactly, reproduced the end point although commencing from a different starting position, or reproduced the same distance from a different starting point. Sighted normal children and blind children performed very similarly on both the reproduction and the location task. However on distance reproduction, the blind children underestimated the longer distances more markedly than did the normals. Autistic children resembled the blind in their attempts to reproduce the longer distances. In addition they had a tendency to overshoot over short distances in all tasks. The results are discussed in terms of the role of a visual reference system for different aspects of motor movements.

The Brain

In order to better understand how our visual system processes information, we must understand the underlying brain connectivity architecture, and how it can get reorganized under visual deprivation. The full extent to which visual development and visual loss affect connectivity is not well known. To investigate the effect of the onset of blindness on structural connectivity both at the whole-brain voxel-wise level and at the level of all major whitematter tracts, we applied two complementary Diffusion-Tension Imaging (DTI) methods, TBSS and AFQ. Diffusion-weighted brain images were collected from three groups of participants: congenitally blind (CB), acquired blind (AB), and fully sighted controls. The differences between these groups were evaluated on a voxel-wise scale with Tract-Based Spatial Statistics (TBSS) method, and on larger-scale with Automated Fiber Quantification (AFQ), a method that allows for between-group comparisons at the level of the major fiber tracts. TBSS revealed that both blind groups tended to have higher FA than sighted controls in the central structures of the brain. AFQ revealed that, where the three groups differed, congenitally blind participants tended to be more similar to sighted controls than to those participants who had acquired blindness later in life. These differences were specifically manifested in the left uncinated fasciculus, the right corticospinal fasciculus, and the left superior longitudinal fasciculus, areas broadly associated with a range of higher-level cognitive systems.
