Imagine a conditioned stimulus CS) and an unconditioned stimulus US) are paired 10 times until the association strength in the Rescorla-Wagner model reaches 1.0 "units." The CS is then presented 5 times on its own.Which of the following is the most plausible value for the final association strength between the CS and US?
A)-0.5 units
B)0 units
C)0.5 units
D)1.0 unit

The Rescorla-Wagner model predicts that the strength of the association between a conditioned stimulus (CS) and an unconditioned stimulus (US) will decrease if the CS is presented without the US, a process known as extinction. Since the association strength reached 1.0 units through pairing and then the CS was presented alone 5 times, it is plausible that the association strength would decrease but not completely vanish, making 0.5 units a reasonable estimate for the final association strength.
