该句暂无译文！
第四段
1 .A while back, some researchers examine about 1,500 portraits painted from the 16th to the 20th century in Western Europe.
该句暂无译文！
2 .And in the majority of them is the left һ side of the face that's most prominently displayed.Why is that?
该句暂无译文！
第五段
1 .And interestingly enough, this tendency to show the left side has diminished over time,
该句暂无译文！
2 .especially in the 20th century.
该句暂无译文！
3 .In fact, the leftһ right ratio is now about 1:1.50% left 50% right.
该句暂无译文！
第六段
1 .Why is that?
该句暂无译文！
第七段
1 .We do know that for many artists, the choice of left side, right side was very important.
该句暂无译文！
2 .There is an image by the Dutch painter Vincent Van Gogh called the Potato Eaters that shows the profiles of a group of farmers.
该句暂无译文！
3 .It's a lithograph, which is a print made from i mages drawn on a stone.
该句暂无译文！
4 .When you print something that way, what you get is a mirror image of the original picture.
该句暂无译文！
5 .The exact same image, except that left and right are reversed,
该句暂无译文！

该句暂无译文！
第八段
1 .Anyway, why do you think so many painters in the past chose to depict the left side of their subjects' face? Nancy.
该句暂无译文！
第九段
1 .Could it have to do with whether the artists were left-handed or right-handed,
该句暂无译文！
2 .like maybe most of them were right-handed, and maybe for some reason they feel more comfortable painting the left side?
该句暂无译文！
第十段
1 .Ok, many right-handed artists do find it easier to paint left profiles, and many art historians think that's the reason for the directional bias.
该句暂无译文！
2 .But if that hypothesis, let's call it the right-handed hypothesis, was correct,
该句暂无译文！
3 .you'd expect that left-handed artists would find it easier to paint right profiles.
该句暂无译文！
4 .But the research suggests that left-handed artists find it just as easy to paint left profiles as right.
该句暂无译文！
5 .So any other ideas?
该句暂无译文！
第十一段
1 .Well, another theory is what's known as the parental imprinting hypothesis,
该句暂无译文！
2 .which proposes that people are more used to seeing left profiles because supposedly right-handed parents are more likely to hold their babies in their left arm.
该句暂无译文！
第十二段
1 .Well, my sister just had a baby and she keeps talking about how her left arm is getting so much stronger than her right.
该句暂无译文！
第十三段
1 .Ok, so there's some anecdotal evidence.
该句暂无译文！
第十四段
1 .So, then when the baby looks up at their parent, what they see is the left profile.
该句暂无译文！
第十五段
1 .Right. And so the theory goes:the left side of the face becomes imprinted in our memories.
该句暂无译文！
第十六段
1 .But the parental imprinting hypothesis doesn't explain why left profiles have decreased over time.
该句暂无译文！
2 .I mean, parents are still carrying their babies in their left arm, right?
该句暂无译文！
第十七段
1 .Exactly! All right, what about the way the artists' studio is organized, specifically the light source.
该句暂无译文！
第十八段
1 .Remember that the light source determines where the shadows are.
该句暂无译文！
2 .So, if you're a right-handed artists, you'd want to the light coming from your left because you don't want your painting hand to cast a shadow across your canvas, right?
该句暂无译文！
3 .And if the light's coming from your left,
该句暂无译文！
4 .ou'd want your subject to turn to their right into the light. If they do that, what do you see?
该句暂无译文！
第一十九段
1 .The left side of their face.
该句暂无译文！
第二十段
1 .Exactly, and well into the 20th century,
该句暂无译文！
2 .many an artist's primary light source would be the sun.
该句暂无译文！
3 .And they set up their studio to take maximum advantage of it.
该句暂无译文！
4 .But then what happens as other high-quality, portable, artificial light sources become available?
该句暂无译文！
第二十一段
1 .Well, you could position your subject in a lot more different ways and still have good lighting on your subject and on your canvas.
该句暂无译文！
第二十二段
1 .So...?
该句暂无译文！
第二十三段
1 .You'd expect to see a more balanced ratio of left- and right-side portraits.
