In the original article, the following sentence:
“They found that increased F2 (i.e., higher vowels) was associated with increased redness on the color spectrum, while increased F1 (i.e., lower vowels) was associated with increased yellowness.”
is incorrect. It should be:
“They found that increased F2 (such as in front vowels like /i/) was associated with increased yellowness and greenness on the color spectrum, while increased F1 (such as in open vowels like /ɑ/) was associated with increased redness.”
This means that Figure 1 is also incorrect. A new Figure 1 is provided here.
