Varied deviation of action time and extracted rapid changes in local Qʹ factor. (a) Subset of action time in ‘short’ trials from 2 h 20 m to 3 h 5 m after the onset of experiment on Day 15 shown in Fig. 2a. Arrows on the left and on the right point to samples of action time with smaller deviation and samples with larger deviation, respectively. (b) A collection of 20 consecutive samples of action times from the target trial that is indicated by the arrow. Filled circles are samples obtained during data collection. Open circles are other samples, not belonging to the data collection. (c) Cumulative distribution of action time in the data collection shown in (b). (d) Median and interquartile range (IQR) measured in local distributions of action time as exemplified in (c). Black filled circles and grey open circles indicate median and interquartile range (IQR), respectively. (e) Rapid decrease of local Qʹ factor in the period shown in (a). Arrows on the left and on the right point to the local Qʹ factors extracted from the samples pointed by arrows in (a). The interval between vertical dashed lines is 10 min. The open arrow represents approximate direction of local Qʹ factor change in the period. (f )The same analysis in a different period in the same daily session. The interval between vertical dashed lines is 10 min, also in (g). (g) Rapid increase of local Qʹ factor in the period shown in (f). Open arrow represents approximate direction of local Qʹ factor change in the period. (h) Temporal change of local Qʹ factor during the task on Day 15 shown in Fig. 2a. Arrows point to rapid changes of local Qʹ factor. The onset and width of R( +) time window in ‘short’ trials were 300 and 700 ms, respectively.
