A Cross-Cultural Study of Environmental Influences and Mechanical Aptitude in Several Indian Groups.
Bowd, Alan D.
Mechanical aptitude is considered to be a composite of several abilities--general intelligence, spatial, mechanical knowledge and comprehension, and relevant manual dexterity and coordination. Abilities are conceived as if organized in a hierarchical model and are assumed to develop as overlearned and generalized response patterns to particular aspects of environmental stimulation. Mechanical aptitude is recognized as a particular grouping of abilities which is the product of a technologically sophisticated society. However, it is proposed that it is of relevance to peoples undergoing acculturation, and that certain aspects of it are likely to show different levels of development in comparison with others. Several American groups of diverse background have been selected (all subjects were 12- to 14-year-old boys) in an attempt to specify the particular aspects of the environment which are likely to relate to mechanical skills. For purposes of comparison a white sample is also included, and to assist in evaluating comparative levels of ability a verbal test is included in the battery. The purpose of the study is not only to evaluate comparative levels of ability, but to compare the factorial structures apparent in one culture group with those developed in others. For this reason the data are analyzed by several factorial procedures and an attempt is made to maximize factor congruence across groups. The results are interpreted as offering general support for the developmental theory of abilities, and the hierarchical model is considered to have useful application in the cultural groups studied.
