A computer-interactive multidimensional scaling
(MDS) program (INTERSCAL) was used together
with free response methods to represent and label
dimensions of individual cognitive structure underlying
person perception. INTERSCAL reduced by
40% the number of judgments required by each
respondent over traditional complete judgment
MDS methods. The dimensional structures derived
by INTERSCAL were predictive of semantic differential
type judgments, Repertory Grid Test triad
judgments, and independent pair-comparison judgments.
Typically, one or two dimensions were recovered
and were labeled evaluative and potency dimensions,
respectively. These dimensional structures
were stable within individuals over a period of
ten weeks. This pattern of overall consistency implies
that particular characteristics of an individual’s
structure and changes in the relative location
of the stimuli over time may be given serious consideration,
and that INTERSCAL is an efficient
method for scaling such dimensional structures.
