Often in conversation, people would make joke with sarcasm and intend to go for small “white” lies with one another. Generally speaking, it is easy for most to tell when someone is telling the truth, and when someone is simply making a joke, However in some cases, the distinction can be fine. As for People having Alzheimer’s and Parkinson’s, or neurodevelopmental conditions like autism spectrum disorder, it is quite difficult to distinguish it. To find more about this, scientists from McGill University have developed a video inventory to offer assistance in knowing better about the cause of such difficulties, and discovered that men usually have more difficulties in identifying sarcasm than women.

As Kathrin Rothermich, co-author of the paper published in PLOS ONE,  from McGill’s School of Communication Disorders said, people tended to believe that people would tell the truth in most cases, So sarcasm and white lies appear to go against a general principle of what ‘should’ occur in daily conversation. This might be part of what made them so difficult to recognize for some.

N order to better understand the reason that people find true intentions during social interactions difficult to appreciate,  Rothermich and her colleague Marc Pell had spent two years so as to work out an inventory of short, scripted (and occasionally awkward) scenes demonstrating two persons in different relationships interacting. Afterwards, they showed these to some healthy participants to see whether they were sure when the characters in the videos were being sincere, when they were making jokes and what vocal and facial cues gave it all away.

From their tests, scientists discovered that generally speaking,people could be certain when the characters were making fun of each other, or when they were telling the truth, however, coming to sarcasm, things turned to be a bit trickier . It was quite interesting that scientists discovered that in comparison with women, men would find it more difficult to understand sarcasm when it was being used. The only case was that when the characters in the short films were pretending to be two friends, that the researchers found that men were found be more capable to be ease with the use of sarcasm.

From these videos, it was easily found that it wasn’t simply the tone in which comments were made, but more important, there was also a mixture of physical cues, for example, facial expressions, and even the relationships between the two characters, helping people understand whether certain comments are sincere or sarcastic. So what you intend to  make comments in a different way depend on what kind person the person you’re talking to, whether he is a close friend, a partner, or your boss. In the most previous studies,focus was given to t the vocal cues in these forms of social interaction.

It is hoped that this new library of videos, nearly 1,000 of them, would be helpful for future researchers in the fields of social cognition, interpersonal communication as well as the interpretation of a speaker’s intentions.
