Research by Vermeulen et al. shows that the brain responds to facial expressions denoting fear and disgust quite differently. Expressions denoting fear heighten our sensory input and increase our attention to the material immediately following the stimuls, whilst a face denoting disgust throttles our sensory input and attention.

What does this mean for adult learning? Using imagery and soundscapes it would be relatively simple to stimulate fear in learners, fear of job loss, fear of poor health and so on, then follow it up with critical information to prevent these fears being realised. As an eLearning consultant, I’ve used this technique quite often, for example using disturbing case studies as an extrinsic motivator, but never with the intent of generating fear.

What about the ethical dimensions this approach? Do the ends justify the fear? Is a good scare what learners need?
