approached significancep =.07
The effect of Expectancy approached significance in Stay trials (F [1, 26]=3.57, p =.07, η 2 p =.121) with Unexpected Outcomes leading to a greater negativity ( M =−1.88 μV, SE=.49 μV) than Expected ( M =−0.35 μV, SE=.73 μV), and was significant in Switch trials (F [1, 26]=58.83, p <.0001, η 2 p =.693) with Expected Outcomes leading to a greater negativity ( M =−6.76 μV, SE=.78 μV) than Unexpected ( M =1.54 μV, SE=.59 μV). 4.3.
