Question 2

Thorndike's Law of Effect suggests that the strength of a stimulus-response connection $S_c$ increases as a function of satisfaction $R$. If $S_c(t+1) = S_c(t) + \alpha(R - S_c(t))$, where $\alpha$ is the learning coefficient ($0 < \alpha < 1$), calculate the steady-state value of $S_c$ as $t 	o \infty$.

S_c = R

Question 6

Consider a cognitive model where the probability of a correct choice $C$ is defined by the ratio of internal weights $w_1$ and $w_2$ such that $P(C) = \frac{w_1}{w_1 + w_2}$. If an agent updates $w_1$ via a learning rule $w_1(t+1) = w_1(t) + \Delta$, find the expression for the change in probability $\Delta P$ in terms of $w_1, w_2,$ and $\Delta$.

Question 8

An organism shows an initial response magnitude of $R_0 = 100$ units. After $n$ trials of a stimulus, the response magnitude follows the decay function $R(n) = R_0 e^{-kn}$. If after $n = 5$ trials the response is $R(5) = 36.79$, calculate the habituation rate constant $k$.
