Study 2: task design and examples of categorization-related shifts in the
perception of emotion in the self. Each participant judged his or her
own affective experience in response to graphic images using a
continuous scale in some blocks and a categorical scale in others (a).
Each image was presented for 6 s, during which time participants were
asked to indicate when they had made a decision concerning the affect
they experienced. Next, following a 2- to 6-s interval, participants
recorded their judgment. For each condition, the average subjective
response (“neutral” = 0, “bad” = 1) for each normative rating level was
then calculated, and the point of subjective equivalence (PSE) was
identified. The difference in the PSE between the conditions indexed the
participant’s categorization-related shift. In (b), the plot on the left
shows results for a participant with a categorization-related shift
(dashed red line) toward “neutral,” and the plot on the right shows
results for a participant with a categorization-related shift toward
“bad.”
