Behavioral results. Data, including response time (RT) from the time perception (TP) task and log-transformed discounting rates (indicated as delay discounting [DD] in the graph above), for baseline (BS) and two different conditions (the left-to-right [LtoR] and the right-to-left [RtoL]) were displayed in different shapes (baseline, circle; the LtoR condition, triangle; the RtoL condition, square). In the graph above, the gray circles represent the mean value across participants. Significant differences are marked with an asterisk (*: q < 0.05). (A) RTs from the TP task in each condition. The TP task RTs showed a significant difference only in the LtoR scenic block, compared to BS. (B) The DD in each condition. The discount rates showed a significant difference in both conditions compared to BS. (C) The correlation between differences in the RTs and the following discount rates between each condition and BS. There was a significant correlation between differences in RTs and discount rates only between the LtoR condition and BS (q < 0.05). (D) The correlation between differences in RTs (each condition—BS) and discount rates for each condition. The RT differences between the LtoR condition and BS tended to be linked to the discount rates for the LtoR condition itself (uncorrected p = 0.032), though this relationship was not significant after correction for multiple comparisons (q = 0.111). This means that in the LtoR conditions, the DD decreased depending on the degree to which TP was changed.
