https://fediscience.org/@coganla...❔3️⃣: There is discussion about why stimulation decreased encoding but enhanced task performance: stimulation reduced ‘excess’ control. We’d be curious to see this stim. setup done using a task-switching paradigm, as it may be that stimulation is improving cognitive flexibility.

https://fediscience.org/@coganla...❔2️⃣:Did the RTs differ between subjects with strong and weak coding partitions on repeat trials? A strong coding partition may make it easier to disentangle information between past and present states, decreasing switch cost, but if past and present states share a lot of information (as during repeat trials), would subjects with a weak coding partition decode these trials faster and thus have a lower RT on repeat trials?

https://fediscience.org/@coganla...❔1️⃣: What would happen the switch was between drastically different tasks (e.g. stop/go task vs. flanker task)? Would the PFC then need to use higher-dimensional subspaces to encode all of the task information? What about for more stimuli/per task?

Perhaps there are factors that lead to one person having a strong/weak coding partition, and also potential dis-/advantages in an educational setting.
