^*Mean of three items, each answered on nine-point scales: How enjoyable and entertaining the thinking period was and how bored participants were (reverse-scored). Cronbach's alpha = 0.89.

^†Extent to which participants reported that it was hard to concentrate on what they chose to think about (nine-point scale; the higher the number, the greater the reported difficulty).

^‡Extent to which participants reported that their mind wandered during the thinking period (nine-point scale; the higher the number, the greater the reported mind-wandering).
