Bayes factors (BF) for the exploratory analyses against the unconstrained hypothesis (Hu) for task difficulty and pleasantness.

Hypothesis	Difficulty/Intrusionsa BFxu	Difficulty/Ratings BFxu	Pleasantness/Ratings BFxu
Ha: µtetris < µwordgamesb	.96.	1.94	.42
Hb: µtetris > µwordgames	1.04	.06	1.56
Hc: µtetris = µwordgames	1.72	.32	1.20

^aNumber of intrusions during the task as an indicator of task difficulty

^b< refers to Tetris being less difficult than Word games, (indicated by more intrusions during the task) and lower difficulty ratings.
