“…Other studies focused on interest (n = 15, 17.44%; e.g., "How interested have you been in what you have been doing?") (Kraft et al, 2022), positive affect (n = 8, 8.45%; e.g., "I felt excited at the time of the beep") (Thompson et al, 2021), anhedonic depression (n = 4, 4.65%; "Felt like I had a lot to look forward to") (Bean & Ciesla, 2021;Kaiser et al, 2024;Kalmbach et al, 2017;Peterson et al, 2021), hedonic experience during activities (n = 1, 1.16%; item not worded) (Kluge et al, 2018), and/or social affective forecasting (n = 2, 2.33%; items not worded) (Shovestul et al, 2022;Wu et al, 2017). Although conceptually similar to reward prediction error, social affective forecasting was typically operationalized as the difference between consummatory pleasure ratings at one prompt and anticipatory pleasure ratings at the previous prompt.…”
