A linked list uses association to link from one item to the next. The exercise in the appendix where you linked a list of fifteen items is an example of a linked list. You might want to review the exercise to see how a linked list works.
You can also use this process to link several related points around a particular topic. Above in the association example we looked at using a polar bear to remind us that a role of oil is to keep the engine cool. The other five main roles of oil are shock absorption, protection, cleaning, sealing and lubrication. To create a linked list for this topic, you would then link the polar bear to an image related to the next item, shock absorption. Perhaps the polar bears have shock absorbers in place of their legs. You would then link those shock absorbers with an image that reminds you of protection, and so on until you have memorized the list.
An issue with this technique is you can “break the chain” if you forget one of the items. It’s then difficult to remember the next item. The next technique, peg words, does not have this issue.
