It’s been two years since the whole Laurel/Yanny situation, an audio clip where some people heard Laurel, some heard Yanny, and sometimes it switched for the listener. The reality is the person was saying Laurel, but the way the said it and the frequency at which it was played had an effect on what people heard.
Something similar has happened again! This time it’s a Tik Tok video that is going viral. Try to listen to the audio without reading the text first.
The video, which first hit the internet in 2018, but has since seen new life after recently going viral on TikTok, has now gone viral, with more than 7.5 million views and nearly 500,000 likes on the popular social media app. The voice appears to say either Green Needle or Brainstorm.
The reality is the toy is based off of the Television show Ben10 and is saying one of the shows character names; Brainstorm.
“The effect seems to work as follows: When you ‘think’ green needle you hear that word, but when you ‘think’ brainstorm, you hear the other,” Valerie Hazan, a professor of speech sciences at University College London, said in 2018.
“Basically, you are priming your brain to expect acoustic patterns that match expected patterns for a particular word,” she added. “When faced with an acoustic signal which is somewhat ambiguous because it is low-quality or noisy, your brain attempts a ‘best fit’ between what is heard and the expected word.”
