I’ll save you the anxiety of guessing and the effort of researching—it’s the third one. Or maybe psychology grad students really are good at Photoshop, and I simply can’t stand pictures of Bradbrad that have been adulterated in any way.

JGordon, what are you talking about?

Aahh, I don’t even know anymore. But I guess I’m referring to this study that recently came out of Vanderbilt University, about how we recognize human faces. It turns out that while we identify most stuff (cars are given as an example in the article) by individual features, individual humans are identified by the whole collection of facial features.

Holistic recognition (the way we see faces) is nice because we can quickly distinguish between lots of individuals. But the reason we’re able to do it so well, say the scientists, is because we associate names with faces, individuating them as we learn them. This is a different mental path than identifying something by individual parts.

Basically, we don’t identify people by thinking “Let’s see… square jaw, pointy nose, thin eyebrows, small ears… ah! That’s David!” And if we had learned to identify people that way, we would have to relearn to identify them holistically by all their features at once, because the two methods of identification aren’t really linked.

Or something. Like I said, I don’t really know what I’m talking about.

The scientists did, however, attempt to illustrate their point with this picture of actor Brad Pitt. The idea is as follows:
“See this picture of Brad Pitt?”
“Yes, I see that picture of Brad Pitt. Very nice.”
“Are you sure? Take a closer look.”
“What on Earth are you… Oh my goodness! The eyes! Those are Matt Damon’s eyes! Well, I never!”
“Yes, those are Matt Damon’s eyes! But you didn’t look at the eyes and say, ‘This is Matt Damon,’ did you?”
“No indeed!”

Except, if you’re anything like JGordon, you looked at that picture and thought, “What happened to Brad Pitt? Has Angelina Jolie been hitting him? Does he have eyeball parasites?” And you were so distracted by this that any future mention of psychology was overwhelmed by your concern for Benjamin Button himself. He’s only a child, after all.

Eh. Anyway, your photo project looks crazy, Vanderbilt.

So here’s a project that researchers must have had a lot of laughs doing. They’ve found that chimps are as likely to remember a fellow acquaintance of their species by their butt as by their face.

Captive chimps were able to match up at a high rate of success photos of rear ends and faces of chimps they’d previously met. Here’s how it worked:

Each participating chimp was flashed a picture of another's rear end, with visible genitals, then shown the face of the derriere's owner and another face of the same gender.

Both males and females were successful in this anatomical match game, pairing faces and posteriors with much greater frequency than chance alone—but only if the photos showed chimps they already knew.

You are now free to go ahead and make up your own J-Lo joke.
