Memories are more solid when the initial experiences are escorted by unpleasant odors, a group of scientists has discovered. The research widens our knowing of what can boost Pavlovian reactions and underlines how negative experiences manipulate our capability of recalling earlier events.
“These outcomes show that bad smells are able to make memory improvements in both adults and adolescents, underlining new methods to research how we remember and learn from negative and positive experiences,” claims the senior author of the paper and assistant professor in Department of Psychology at New York University, Catherine Hartley, claimed. This study is posted in the Learning and Memory journal.
“Since our results spanned different groups of age, this research shows that unpleasant odors may be employed in the future to study memory processes and emotional learning all over development,” claims the lead author of the paper and an NYU postdoctoral fellow, Alexandra Cohen, to the media.
The affect of off-putting experiences on memory has long been demonstrated—and is well known to us. For instance, you might develop an off-putting memory of a dog if you are bitten by that dog, and your negative relation might also go on to oversimplify to all dogs. In addition, due to the trauma covering the bite, you are expected to have a better recollection of it as compared to what you might have with other dog past experiences.
On a related note, study by the University of Chicago neuroscientists displays how working, short-term memory employs neuron networks differently relying on the complexity of the task in question.
The scientists employed modern AI methods to train CNN to resolve a series of complicated behavioral tasks that needed storing data in short term memory. The AI systems were based on the biological framework of the brain and disclosed two distinct procedures comprised in short-term memory.
