M.A. (Psychology)
Spatial ability as a cognitive ability has for some time been recognised as a distinct component in the intellectual make-up of the individual. Since the earliest identification of spatial ability in the 1920's, interest has been shown in the fuller understanding of this ability. Many controversies still exist since spatial ability has yet to be defined in a definitive manner. Spatial ability has received relatively little attention. Since a relationship between spatial ability and occupational success has been established, more interest
has been shown in this field. Spatial ability is as important as language for survival in the business world and more so in the technical field. Spatial ability is synonymous with the socalled "minor" hemisphere. The importance of the "minor" hemisphere and in particular the link between the right hemisphere and the language centres of the left hemisphere, has recently been. recognised. This recognition is found where the right
hemisphere together with the damaged left hemisphere may be included in a rehabilitation programme. Spatial ability is the product of environmental influences
which include child rearing practices, education and nutrition. Other influences are of a genetic, hormonal and neurological nature. Associated the concept
terms, the associated with of left with the cognitive functions of the brain, is
lateralisation of functions.
