“…However, there have been inconsistent findings across studies, likely due in part to variability in characteristics of the task. Specifically, delay discounting is influenced by reward magnitude (Myerson & Green, 1995), delay length, type of reward (e.g., monetary versus non-monetary) (Chapman & Elstein, 1995; Demurie, Roeyers, Baeyens, & Sonuga-Barke, 2013; Friedel, DeHart, Madden, & Odum, 2014; Killeen, 2015), and whether the rewards are immediately consumable (e.g., food versus money) (Forzano, Michels, Sorama, Etopio, & English, 2014). We recently found ADHD-associated increases in delay discounting to be specific to girls and specific to a novel real-time discounting task involving immediately consumable rewards, but not a classic monetary discounting task, suggesting that inconsistent findings across studies may also be due to task differences or individual characteristics such as sex (Rosch & Mostofsky, 2016).…”
