Sampling scheme of Study 1

Time of day	Experimental group
	Low sampling frequency	High sampling frequency
9:00–10:40	Questionnaire 1	Questionnaire 1
11:00–13:50		Questionnaires 2–4
14:10–15:50	Questionnaire 2	Questionnaire 5
16:10–19:00		Questionnaires 6–8
19:20–21:00	Questionnaire 3	Questionnaire 9

Note. The displayed sampling scheme refers to the first of the two time schedules from which participants could choose (9:00–21:00 vs. 10:30–22:30). That is, in the second time schedule, each questionnaire was scheduled 90 min later. For each questionnaire, participants had the option to delay their response for up to 15 min. In the high sampling frequency group, Questionnaires 2, 3, and 4 and Questionnaires 6, 7, and 8 were at least 28 min apart.
