Tone deaf people may find it harder to tell if a laugh is fake or read facial expressions

Being tone deaf could affect more than just your karaoke ability. A new study shows that being unable to recognise musical pitch could also have a serious affect on social skills. People with'congenital amusia' - the scientific term for tone deafness - may find it more difficult to accurately read facial expressions or tell if a laugh is fake, according to a new study. As part of the study by researchers from Goldsmiths, University of London and University College London (UCL), 24 participants were asked to judge the emotion in extracts of speech, based on patterns hear in the tone of voice. Some people claim they're born to sing, while others openly admit they're tone deaf, but what if you could take a pill and become pitch perfect?
