“…Most studies that have successfully manipulated delay of gratification have involved the provision of specific techniques to delay, such as providing children task‐specific cognitive strategies (e.g., look away from the marshmallow, Mischel & Ebbesen, ; ‘imagine the marshmallow as a cloud’; Mischel & Baker, ). Other work suggests that providing children with a personal or group identity associated with self‐control can increase delay (e.g., a Superman cape, Doebel & Munakata, ; Karniol et al, ; Toner, Moore, & Emmons, ; see White & Carlson, ; White et al, for similar examples). Instead, we used a model to represent the idea that exerting self‐control can be energizing.…”
