Deceptive Perception

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.
