Topology of the transition probabilities in the dHMM. Hidden states are denoted by circles, and transitions among hidden states are denoted by arrows, along with their probabilities. The beginning of the sequence is denoted by π. The capital letters on the right denote the experimental sessions with different mental-rotation strategies (LFRR = left-side-fixed right-side-rotated, RFLR = right-side-fixed left-side-rotated), and the small letters within the circles denote the names of the hidden states or processes (e = encoding and searching, c = comparison, s = searching on one-side pair).
