Figure 2a Dimensions 1 and 3 of the affective perceptual space produced by the PREFMAP
analysis
This research used the SD method and MDS analysis to construct an affective
perceptual space, labeling the 3 axes ‘Liveliness & Creativity,’ ‘Refinement,’ and
‘Technicality.’ This space enabled visualization of users’ affective responses to
each blog interface. MDS’s PREFMAP algorithm could plot affective response data
into a perceptual space of blog interface similarity (ALSCAL). Examining how the
visual features of the sample blogs are distributed along the dimension axes of the
space allowed more objective identification of the important
