This distinction is important because it relates to an effect in psychology known as the " positive feedback bias" : teachers tend to give Black students more positive and less critical feedback than they give to the students' white peers.

这种区别很重要，因为它与心理学中被称为“积极反馈偏见”的效应有关：与白人学生相比，教师倾向于给黑人学生更多积极、更少批评的反馈。
