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.
What is double dissociation example?
Double Dissociation is when two related mental processes are shown to function independently of each other. A classic example of Double Dissociation is speech and language comprehension. Although both processes pertain to use of language, the brain structures that control them work independently.
What is the difference between a dissociation and a double dissociation?
Establishing a single dissociation between two functions provides limited and potentially misleading information, whereas a double dissociation can conclusively demonstrate that the two functions are localized in different areas of the brain.
What is double dissociation brain damage?
The paradigm of double dissociation is of considerable historical importance. The term, first proposed by Hans-Lukas Teuber (1955), refers to a situation in which a lesion of brain area A impairs function 1 but not function 2, while a lesion of brain area B produces the reverse pattern.

- Focused Attention: Refers to our ability to focus attention on a stimulus.
