David Brang of the department of psychology at the University of California, San Diego asked 183 students to visualize the months of the year and construct this representation on a computer screen.

Four months later the students were shown a blank screen and asked to select a position for each of the months. They were prompted with a cue month – a randomly selected month placed as a dot in the location where the student had originally placed it.

Uncannily, four of the 183 students were found to be time-space synaesthetes when they placed their months in a distinct spatial array – such as a circle – that was consistent over the trials.
