Object Location Memory Test

Remember where each object sits in the grid, then put every one back in its place.

Object Location

~2-4 min

  1. A few objects appear in a grid. Remember where each one is.
  2. They disappear. Tap an object in the tray, then the square it was in.
  3. Six rounds, from 3 objects to 8. Each object in the right square scores.

Link each object to a corner or a neighbour: the moon above the key.

Your result: — / 33

How does the object location memory test work?

A few objects appear in a 4×4 grid: a star, a key, a moon and so on. You have 1.2 seconds per object to study them; then they vanish and wait in a tray. Tap an object, then the square where it was. Tap a placed object to pick it up again. When all are placed, press Check to see which were right. There are 6 rounds, from 3 objects to 8.

How is your result calculated?

Every object put back in exactly the right square scores one, out of 33 across the 6 rounds. You also see how many rounds you got entirely right. Placing is not timed.

What does object location memory mean?

Object location memory is remembering what was where: not only which squares were used, but which object was in each. That takes binding each object to its place, which is why swapping two objects costs two points here even though every used square is filled. It is the kind of memory you use for where you left your keys.

How to remember where things are

  • Link objects to each other. "The moon is above the key" is easier to keep than two separate positions.
  • Use the corners and edges. Objects in corners are easy; place the middle ones relative to them.
  • Make a quick story. A star falling into a cup takes one image to remember instead of two facts.

This is a recreational memory game, not an assessment. For memory for lit squares alone, try the Visual Memory Test; for memory for order, the Sequence Memory Test.

Questions

What is object location memory?
Remembering what was where: which object was in which place. It is tested here by putting each object back in its own square.
Does it matter which object goes in which square?
Yes. An object only scores in its own square, so two objects swapped score nothing, even though both squares were right.
How long do I get to study?
1.2 seconds per object, plus a short moment to settle: about 4 seconds for three objects and 10 for eight.
Can I move an object after placing it?
Yes. Tap a placed object to pick it up again, until you press Check.
Is this a test for memory problems?
No. It is a game, with no norms. If you are worried about your memory, talk to a doctor.
