Yet Another Reason Why We Need To Be Positive With Our Students

| 0 comments

From The Optimism Bias by Tali Sharot: extract in The Guardian:

To induce expectations of success, she primed college students with words such as smart, intelligent and clever just before asking them to perform a test. To induce expectations of failure, she primed them with words like stupid and ignorant. The students performed better after being primed with an affirmative message.

Examining the brain-imaging data, Bengtsson found that the students’ brains responded differently to the mistakes they made depending on whether they were primed with the word clever or the word stupid. When the mistake followed positive words, she observed enhanced activity in the anterior medial part of the prefrontal cortex (a region that is involved in self-reflection and recollection). However, when the participants were primed with the word stupid, there was no heightened activity after a wrong answer. It appears that after being primed with the word stupid, the brain expected to do poorly and did not show signs of surprise or conflict when it made an error.

A brain that doesn’t expect good results lacks a signal telling it, “Take notice – wrong answer!” These brains will fail to learn from their mistakes and are less likely to improve over time. Expectations become self-fulfilling by altering our performance and actions, which ultimately affects what happens in the future.

I’m adding this information to My Best Posts On Why It’s Important To Be Positive In Class.
