When attention and memory disagree
Here is a heat map from a neuroscience study I was completing where I wanted to see what happens in a buyer's brain when a vendor shows a problem that the buyer has (left page in a printed handout) vs. the vendor's solution (right page). Notice the more intense attention to the problem than the solution. This might not be a bad thing because it may mean that the solution was so easy to understand that it did not demand that much attention. However, after 48 hours, the buyers remembered the problem more so than the solution (which did not make the vendor very happy!)
However, this contrast (high attention but low recall vs. low attention but high recall) offers powerful insight into how attention and memory don’t always align.
First, some observations as to why the results may be so. The problem was fairly complex, involving more mental effort. In addition, humans like dwelling on problems; we have a negativity bias because we like to protect ourselves. In addition, emotion and relevance will contribute to someone's memory. It’s possible that the problem, in this case, was heavy, but the solution was light.
So, what practical guidelines can we learn from this? A serious problem deserves more than a generic solution. If there’s emotional weight on one side, match it with emotional relief on the other. Consider an “emotional solution,” not just a logical answer to a heavy problem.
But let’s consider the worst-case scenario: imagine that a solution is not easy to pair with a strong emotion. If we want people to remember it, we can use other pathways to memory, such as repetition and distinctiveness. For example, this brochure did have more pages, so the design can reinforce the solution in multiple spots.
