iScale: Studying Long-Term Experiences through Memory - Modeling Users' Experiences with Interactive Systems - page 90

Fig. 5.2 In the constructive iScale (top), one starts by plotting points in a serial order (feed-
forward progression) and participants are asked to report details of experiences right after a
line segment was added (concurrent reporting). In Value-Account iScale (bottom), a line con-
nects the start with the end and participants may further split this in distinct periods (top-down
progression). Once participants have graphed the full pattern of change over time, they are
asked to report on one or more experiences for each line segment (non-concurrent reporting)
