(This is an excerpt from the book Pomodoro Technique Illustrated)
In 1933 Hedwig von Restorff performed a set of memory experiments. Her conclusion was that an isolated item, in a list of otherwise similar items, would be better remembered. If I read a shopping list with one
item highlighted in azure blue, it’s more likely that I remember the highlighted item than any of the others. This is now identified as The
Von Restorff effect.
The Now List is not another artifact in Pomodoro Technique. It’s my name for a concept: what I give my attention to right now. The cardinality of my Now List is binary. Either I focus on 1 activity or 0 activities. It can
never be 2, 3, 4 or any other number of activities. Before I wind up the clock, I choose one single activity. My challenge during a 25 minute Pomodoro is to not give another activity attention for a minute or two.
The Von Restorff effect tells me that I can provoke my memory to store things that I highlight. I may use a highlighter felt-tip pen to mark the current activity on the To Do Today sheet. Or I can explicitly write the
activity title on a slip of paper and put it in front of me.
