Thus, the evidence from double dissociations does not support modularity, although it should be noted that lack of dissociation is not evidence against a module; this inference cannot be logically made.

Along with double dissociations shown in monkeys, DF s experience is good evidence for the two streams theory of visual perception and shows that the dorsal stream alone provides information for aperture scaling.

Prosopagnosia has been shown to have a similar double dissociation as phonagnosia in that some patients show an impairment of memory for familiar faces while others show impairment when discriminating familiar faces from unfamiliar ones.

In cognitive neuroscience, double dissociation is an experimental technique by which two areas of neocortex are functionally dissociated by two behavioral tests, each test being affected by a lesion in one zone and not the other.

This phenomenon of double dissociation can be an indicator of domain-specific disorders of awareness modules, meaning that in anosognosia, brain damage can selectively impact the self-monitoring process of one specific physical or cognitive function rather than a spatial location of the body.

Double dissociation occurs when brain damage impairs task A in Patient1 but spares task B and brain damage spares task A in Patient 2 but damages task B . It is assumed that one instance of double dissociation is sufficient proof to infer separate cognitive modules in the performance of the tasks.

This possible double dissociation involving HD and DAT patients suggests that different implicit memory tasks are mediated by distinct neural systems and that these tasks can be used to differentiate some of the so-called " cortical " ( e . g ., DAT ) from " subcortical " ( e . g ., HD ) dementias ( Cummings and Benson, 1984 ).

Subject 1 with a lesion in the " A " region of the brain may show impaired functioning in cognitive ability " X " but not " Y ", while subject 2 with a lesion in area " B " demonstrates reduced " Y " ability but " X " is unaffected; results like these allow inferences to be made about brain specialization and localization, also known as using a double dissociation.
