While I believe behavioral cognition to be a combination of Ni and Ne, a review of the thoughts and work of Tolman, an IEE, has lead me to believe that learning and conditioning are primarily delta NF affairs.
As such, it seems to me that an IEE EM type disposes a person to interest in the process of learning. Learning, as defined in An Introduction to Theories of Learning (Hergenhahn & Olson), is the intake of stimulie for the purpose of enhancing ability. Ability falls under delta Ne, therefore the prioritization of ability enhancement reflects delta Ne in a valued position. As far as it is selected as a fixation of attention, ability reflects delta Ne in the dominant EM position (movement from a state of null ability to one of having ability)
