Speech misperceptions are fairly common due to the
importance of our ability to keep up with a conversation in troubling
environments. People are scratching their heads over a viral video of a toy
that is circling the internet right now. The toy is activated and says a word
that can be perceived as both “Brain Storm” and “Green Needle”. It is
impossible to hear both words at the same time, what you hear completely relies
on what you are expecting to hear. Helen Blank, Matt Davis, and colleagues
presented a study to investigate speech misperception. Their findings showed
that reduced activity in the left superior temporal sulcus was the cause of
misperception. Their research strengthens the idea that speech perception
relies heavily on what we expect to hear.
