We're basically testing a hypothesis regarding a possible "malfunction" in how sounds are categorized when being attached to the letter symbols. The experiment (see previous post for a write-up of it) will entail the subjects (a) learning either a phonemic or graphemic rule, and (b) task switching to a new rule during the middle of the experiment without their knowing. The hypothesis is that if they start with a phonemic rule, it will take longer to learn but they will be able to normally switch to the graphemic rule. Whereas if they start with a graphemic rule, they will have no trouble learning it and will either not be able to pick up on the new rule or will take longer in general to learn it compared to the control subjects. We're starting with normal-reading adults while we fine tune the testing materials we will be using. We started off with two educational tests and one cognitive task, but after today's meeting it may increased to as much as 5 tests and 3 cognitive tasks once we are set to test the child population.
