Table 2. Parameter priors.

Values of the hierarchical prior over state transitions taken from [33].

Variable	Prior
State transition distribution	${\widehat{\pi }}_i\sim \text{Dirichlet}({\alpha }_0/K,\dots ,{\alpha }_0/K,{\alpha }_0/K·ϵ)$
Observation distribution	$\widehat{\varphi }\sim \text{Dirichlet}(0.8,0.8,0.8,0.8)$
Response time parameters	τ0 ∼ Γ(1, 10)
	μ ∼ Γ(1, 0.1)
	σ ∼ Γ(1, 0.01)
Hierarchical prior over state transitions	α = 1.3
	γ = 3.8
