Frequencies of experienced run lengths and streak lengths [mean (SD)]

Run lengths		Winning streaks				Losing streaks
Run length	All expts	Streak length	Expt 1	Expt 2	Expt 3	Streak length	Expt 1	Expt 2	Expt 3
1	44	1	23 (±2)	23 (±2)	23 (±2)	1	23 (±2)	23 (±2)	23 (±2)
2	24	2	11 (±2)	12 (±2)	11 (±2)	2	11 (±2)	11 (±2)	12 (±2)
3	9	3	6 (±2)	6 (±2)	5 (±2)	3	5 (±1)	5 (±2)	5 (±2)
4	7	4	3 (±1)	3 (±1)	3 (±2)	4	3 (±1)	3 (±1)	2 (±1)

Nb. run length was experimentally controlled and thus did not vary between experiments or participants. Feedback was not under experimental control, and therefore, the average frequency for each level of winning and losing streak length is presented.
