When viewing televised coverage of sport events, it is noticeable to hear
commentators frequently refer to the body language of competing players while
also speculating on the level of con!dence of those performers. For example, one
often hears the following statements: “You can tell that the player has given up,”
“From looking at their body language one suspects they’ve lost their self-belief,”
or “The team look buoyant and really high on con!dence.”
