double dissociation

a research process for demonstrating the action of two separable psychological or biological systems, such as differentiating between types of memory or the function of brain areas. One experimental variable is found to affect one of the systems, whereas a second variable affects the other. The differentiating variables may be task related, pharmacological, neurological, or individual differences. For example, double dissociation has been used to separate declarative memory from procedural learning. [developed by Hans-Lukas Teuber]
