text: The structure of the T-maze is, as the name suggests, a T-shaped maze, consisting 
  of a centre location, a cue location (bottom of the T), and reward and loss locations (one 
  in each arm of the T) (Figure 2). On every trial, the agent can move to one of the two 
  arms of the T to receive a reward; one, called the reward location, will yield rewards with 
  a higher probability than the other side. At the cue location, which the agent can move 
  to, the agent receives a cue that indicates which of the locations is the reward location. 
  Generally, the cue may be more or less informative; in this example, it always accurately 
  reflected the reward conditions state (reward in the right or left arm). The reward location 
  only provides a reward probabilistically. This means the agent can either take a chance 
  and go directly to one of the two upper arms, or spend its first move seeking information 
  about where the reward is before moving to the reward location. Since the clue location 
  is not preferred, the second option comes with a cost in terms of pragmatic value, which 
  has to be outweighed by the epistemic value in resolving uncertainty about the reward 
  location state. Note that for the agent to realise that this uncertainty reduction will aid it in 
  its subsequent choice of arm, it would have to be able to anticipate the effect of its actions 
  on its own future beliefs, a process called “sophisticated inference” [58].
