It may be necessary for the task, to have the virtual rat learn only the forward direction through the T-maze, not returning from the goal to its initial location. If this is so, then learning in ECIII that currently depends on exploration on the return trip must be achieved differently. Either (a), the reverse path can be learned with a reverse STM buffer for ECIII. Or (b), the backward-spread hypothesis can be replaced with a forward-only hypothesis of learning and navigation.
The experimental branch of the base model to be used for the reversal learning task is stored as: reversal-learning.ccm.
A forward-only implementation will be persued in parallel to this and may be used as a basis for future versions of the reversal task model. The first implementation of the reversal task model should use a STM buffer with reverse item pair order.
