Fun Online Test: The Face in the Branches

Post Reply New Topic

The test was too fast for me.

/gave up

Face In The Fence - Your score was 96. The average score is 91.38. You scored higher than six out of every ten people who took this test.

Old-New Women - Your score was 40. The average score is 38.97. You scored higher than three out of every ten people who took this test.

Face In The Noise Branches - Your score was 95. The average score is 88.18. You scored higher than seven out of every ten people who took this test.

For the Old-New women test, I was mostly guessing.

Face In The Branches -
Your score was 55. The average score is 60.85.
You scored higher than one out of every ten people who took this test

Old-New Women -
Your score was 36. The average score is 38.97:
You scored higher than one out of every ten people who took this test

Face In The Big Branches -
Your score was 85. The average score is 90.54
You scored higher than one out of every ten people who took this test

the branches test was me guessing half the time since i mostly didnt see anything.

I sucked at this:

Face in the Branches: 47

Old New Women: 31

Face in the Fence: 82

I was guessing for most of it. I'm prosopagnosic, and I'm pretty sure I have the subtype of prosopagnosia where the fusiform gyrus works fine but has no interest in faces. (Fusiform gyrus does highly specialized recognition, in most people it does face recognition and in experts it does recognition of area of expertise.) If my brain doesn't single out faces as important, it explains why I'd have trouble detecting faces among a jumble of other things.

You're assuming it's normally distributed. A normally distributed sample will have the mean, median and mode all be the same. If the test results aren't normally distributed (for example if they have a ceiling effect) then a few extremes on one tail will pull the average out.

For example (very small sample because I can't be bothered to make up too many numbers), let's say you have this pattern of scores on one test:

16
2
15
16
17
15
14
16

The average is 13.88, lower than all but one of the individual scores. That's because the outlier 2 dragged it down. The mode is 16, and the median is 9.5.

If 17 was the highest possible score you could get on the test (ceiling effect - most people score close to the maximum), then a larger sample wouldn't help matters. If even a few were very low, they would exert a disproportianate effect on the average because it's impossible to get an extreme outlier in the opposite direction to balance it out.

*Brain drain*

It's taxing enough just to read the instructions.

Backpack in the Branches: 54 (felt utterly impossible, right?)

That test took too much effort, ha.

I didn't make it through. That was really uncomfortable.

They say they think people will be able to find faces in branches easier than backpacks, but they made a mistake in the way they presented the information. The backpacks were on a background of warped, stretched shapes - very easy to mistake one of the lines in that for a solid line in the backpack shape at a quick glance. The faces, however, were on a relatively solid background, making it ridiculously easy for me to pick out the solid lines or blocks of color of the faces at a glance. I wasn't "recognizing a face" I was just finding something that stood out from the background. So I scored higher on finding faces in the branches, but it had nothing to do with the fact that it was faces instead of backpacks, and everything to do with the background they were placed against. They should have used the same background for both - why on earth would they use different ones, unless they are trying to skew the results?

I left a note about this in the comments section at the end. I hope they will try the experiment again with a better setup, otherwise their results are meaningless.

Anyway, I did a lot better than I expected at the old/new faces part. I have terrible trouble recognizing the faces of people I haven't known for a very long time. So many awkward accidental meetings where someone said hi to me and I knew I had probably seen them somewhere before but had absolutely no idea where, then it turned out to be someone I had seen *many* times before, but they were wearing a different jacket or something so I had no idea who they were.

There's an object version of this too, where you spot backpacks instead of faces. Here's my score:

If you look back in the test, my 'face in the branches' score was 47, much lower than the average 91. So I'm better at spotting backpacks quickly than faces.

Honestly, I could not readily identify any faces in the branches except maybe 3 times, and for those three times, I wasn't sure if it was a face or not. For the first 3 sub-tests I scored above average even though on each of them I had a "disobedient finger" that pressed the wrong number and I was aware I pressed the wrong number (meaning, my brain picked "1" and my finger picked "2"), but for the last one it says "You scored higher than zero out of every ten people who took this test." I probably would have scored better if I would have just picked a number and stuck with it. Because I honestly couldn't see any faces.
