Memories are more easily accessed, in humans, when contextual information is brought to mind. When making observations that lead to memories, if the context is relevant to the questions that you will attempt to answer in the future, you will not have to artificially call forth the contextual info. The solution is to approach new situations critically.

So, if you explore a neighborhood, before you set out determine what you will look for. For instance, ask yourself: Are architectural features related to the relative affluence of the area at the time of each building's construction.

Or, in math classes, consider what the lessons build upon and where they may lead.

Consider new situations with conscious consideration of previous knowledge. "Blankness" is not appropriate when approaching an experience in which you have previous expertise. Calling to mind relevant experiences helps to ensure that memories attain relevant associations.
