Abstract
Flexibility of implicit knowledge. Implicit learning and implicit report can be demonstrations of a same cognitive system that processes information without conscience. This system has a series of characteristics that differentiate it from the conscious cognitive system. One of these characteristics, the robustness or inflexibility, it is the object of the present work where we attempted to replicate the positive and negative transfer effects found by Lee and Vakoch (1996). The results of the experiment showed that these transfer effects can be limited to tasks that are similar to the tasks learnt in the acquisition phase.
