Multisensory environments actually stimulate learning. Smell stimulates coding in memory and remembering information. People remember more when they see and hear information at the same time, as in multisensory presentations that stimulate creativity and problem-solving skills.
Trainers should follow John Medina’s Brain Rule #9 that says to stimulate more of the senses. We can do that by using multimedia presentations, animations, exhibitions, demonstrations, relevant music, sounds, textures, or even by branding our training through a certain smell (that can be used later on by our participants to facilitate remembering the information better).
For those who have sight, vision is the strongest and most impactful of the senses.
When it comes to remembering information, pictures are an incredibly efficient tool. If we hear a piece of information, we will remember just 10% three days later. If we add a picture, we will remember 65% (John Medina, Brain Rules).
Visuals are even more effective than text. Medina says this might be because our brain sees words as a set of tiny pictures that must be analysed and compiled in order to be able to read—quite an inefficient process. A picture allows the brain to associate meaning much faster, and to recover that meaning faster too.
In order to capitalize on the incredible power of vision, trainers should:
