Visualization Ability

In research on cognitive issues in automation, spatial visualization ability (SVA) was investigated as a mediator of performance. Prior to performing the experimental task in a simulation environment, 83 undergraduate psychology students completed an on-line version of a test of SVA. The two basic experimental conditions were “monitoring” and “on-call.” In the monitoring condition, participants monitored status messages and responded to system alerts. In the on-call condition, participants performed an unrelated task in between responding to alerts. Dependent measures included decision accuracy. A correlational analysis of SVA scores with decision accuracy found a higher correlation for men than for women. Further analysis indicated that SVA was not a significantly stronger predictor of performance for men than it was for women in the simulated environment. With a larger sample size, however, differential prediction is likely. If confirmed, this finding has implications for the use of SVA in personnel selection. Textual and tabular alternatives to graphical displays may be helpful to low-SVA users.

Visualization Ability

The attitude towards computer-related tasks, computer anxiety, and spatial visualization ability (SVA) of a group of first-year computer science students were measured just before their study commenced. The results were analyzed empirically based on two independent variables, i.e., culture and computer experience. It was found that African and European users generally have the same attitude towards computer use. Users’ attitudes improved after experience with computer-related tasks. African students experienced significantly higher levels of computer anxiety than their European counterparts with the same amount of experience. It was also found that African users generally have a lower SVA than European users. Users with higher SVA generally have a better attitude towards working with computers and experience a lower level of computer anxiety.

Visualization Ability

Studies involving the inheritance of primary mental abilities in twins have generally shown that spatial ability appears to be the ability most influenced by hereditary factors (Thurstone, Thurstone, & Strandskov, 1955; Vandenberg, 1965). Stafford (1961), using the Identical Blocks Test as a measure of spatial visualization, demonstrated that a sex-linked recessive gene may be involved in the transmission of spatial abilities. The present study represented an attempt to replicate Stafford's earlier work, using a test which represented a reasonably pure measure of spatial visualization ability.
