(Co-authored with Steve Smith and Dylan Vinales)
Last week, during a workshop on vocabulary learning that I delivered in my faculty, I carried out a little experiment with my colleagues which aimed at raising their awareness of the limitation of human working memory by making them experience cognitive overload (i.e. the inability of working memory to cope with a task due to excessive demand on their processing capacity).
The task was simple. One person had a list of twenty words and had to utter each word on the list, one by one ( first word 1, then word 2, followed by word 3, etc.) to their partner. The latter had to repeat at each round all the words read so far, rigorously in the same order as they had been read to them ( relying solely on their memory as they had not access to the list).
