Delayed Matching to Sample (DMS)

Delayed Matching to Sample (DMS) is a cognitive task used to assess memory and learning. In this task, a person is shown a sample item (like a shape or color), then there's a delay period with no stimuli. After the delay, they’re presented with several options and must select the one that matches the original sample. The task evaluates how well someone can retain and recall information after a pause. It's often used in research and clinical settings to understand memory function and cognitive abilities in both humans and animals.
