Derivation of the predicted transitions (cf. Brandstätter et al., 2008).

Type of transition	Reading phase	Choice phase				Choice and reading phases
		Priority heuristic			Expectation model	Priority heuristic						Expectation model
		r = 1	r = 2	r = 3		r = 1		r = 2		r = 3
						No.	%	No.	%	No.	%	No.	%
Outcome-probability	4	0	1	1	4	4	50	5	50	5	42	8	57

r = 1, one-reason choices; r = 2, two-reason choices; r = 3, three-reason choices.
