It may be a question you remember from graduate school: What's the deal with sensory extinction? Is it a form of extinction? Of punishment? Or, is it something else? This week, we revisit that old chestnut by discussion four articles that hope to solve the mystery of sensory extinction. And we review one of the most complementary replication articles of all time!
