A new study shows that an iOS (iPhone, iPad, etc.) app yields results on a dichotic listening test that are as reliable as laboratory tests.
Two years ago, psychology researcher Josef Bless was listening to music on his phone when he suddenly had an idea. “In dichotic listening, each ear is presented with a different syllable at the same time (one to the left and one to the right ear) and the listener has to say which syllable seems clearest.
The test indicates which side of the brain is most active during language processing,” Bless explains.
The free app for dichotic listening is called iDichotic; it was launched on the App Store in 2011. Now, more than one year later, more than 1,000 people have downloaded the app, and roughly half have sent their test results to the researchers’ database.
