[Abstract]: Choosing a response format is a problem when designing computerised tests.
Programmers often solve this problem by highlighting a response option and
allowing the user to select this option or choose another by using the cursor keys.
It is possible that such well-meaning attempts to make computers more userfriendly
may heighten response style tendencies. The two experiments to be
reported in this study were designed to test the effect of cursor positioning in
personality and ability tests. In the first experiment, sixty two Participants were
randomly assigned to two groups and asked to complete computerised versions of
Forms A and B of the Eysenck Personality Inventory. The position of the
highlight was manipulated to produce a two-by-two factorial design with repeated
measures on one factor. Results showed that there was evidence of a cursor effect
but that it was confined to one of the conditions in the design. Experiment two
employed the same sort of manipulation in a computerised version of the ACER
Word Knowledge Test with another sample of 36 participants. Here, no evidence
was found for any effect of cursor positioning. Overall, it was concluded that the
highlighting technique itself is unlikely to have any effect on measures of
cognitive ability but that it may have some effect in the more subjective
personality testing domain.
