Transfer occurs at a subconscious level if one has achieved automaticity of that which is to be transferred, and if one is transferring this learning to a problem that is sufficiently similar to the original situation so that differences are handled at a subconscious level, perhaps aided by a little conscious thought(Perkins, David N. and Salomon, Gavriel (September 2, 1992). Unfortunately, researchers are unable to develop a general theory of educational transfer of learning. This would allow students to get better at applying and mastering the idea of transfer in an educational setting.
