Question

Quizplus · Accepted Answer

A double dissociation involves two separate groups with opposite symptoms, which is what is seen in this scenario: one patient can understand spoken English but not speak it fluently, while the other patient can speak English fluently but not understand it when spoken to. This is in contrast to a single dissociation, which involves only one group having symptoms while the other group does not. Experience-dependent plasticity refers to the ability of the brain to change and adapt based on experience, and is not relevant to this scenario.
