Im not sure who or how this was determined but having read your query I felt that I had to find my own answer.
Results below
I put a large square block into a goldfish bowl,That was scientifically measured to allow a goldfish to swim round It In exactly 3 seconds.
I let the goldfish go and he swam around the block Taking 3 seconds
I did this several times for accuracy.
I then waited for It to swim round the corner and noted that as It came round to Its start point and saw me It had Its mouth open as If surprised to see me.
Again this was carried out several times to make sure that this was not a fluke.
I think this proves beyond doubt that the 3 second memory span has been proved.As the goldfish who we will call (JAWS) for the purpose of this experiment was unable to recognise who I was
I hope this clears this question up for you and you can devote your attentions to other questions that may be bothering you
I have put my experimentations onto to DVD If you would like a copy.
