A probabilistic graphical model showing a deep generative model with second-order, attentional states. This deep generative model includes a new level of states, denoted s⁽²⁾, which conditions the precision on the first-order likelihood mapping A⁽¹⁾. Attentional policies, π⁽²⁾, represent mental (covert) actions that condition transitions between attentional states. Adapted from a template given in Figure 4 in the study by Hesp et al. (2021).
