Answer:
Visual encoding
Step-by-step explanation:
When we try to remember a list of things it's easy to forget things. There are many methods that can help us to remember things in an easier way. One of these methods is visual encoding.
Visual encoding basically refers to the process of using visual images to remember information, by doing this, we create a picture in our head containing the elements we need to remember and this way it will be easy to remember them.
Darla successfully remembers the items by picturing herself sipping wine in her slippers, while Robert gives her a sponge bath. This means Darla created a picture in her head including all the items she needed to pick up from the store and therefore she used visual encoding.
