Table 4.

Stop-Signal Response Rate Changes Within Go Bias and Stop Bias Blocks

	Go Bias			Stop Bias
	Early	Middle	Late	Early	Middle	Late
Reinforcement	.27 (.20)	.26 (.23)	.22 (.20)	.56 (.20)	.63 (.22)	.71 (.23)
Strategy-Only	.25 (.16)	.42 (.20)	.44 (.22)	.73 (.14)	.79 (.16)	.82 (.13)

Stop-signal response rates were averaged over the first ten stop trials (Early), the second ten stop trials (Middle), and the last ten stop trials (Late) for each Motivation block. Standard deviations are in parentheses.
