Two reasons are at the cause of this: Emotions such as joy, fear and sadness can all be gathered reliantly on just a person’s face.
Patients suffering from FTLD offer information on the biological complexity involved in generating self-conscious emotions.
Acquiring the ability to perform self-conscious emotions may be relatively difficult, but does bring benefits.
Equally performing in a situation while not sticking to the social norms can leave individuals feeling embarrassed.
An example of this is a study (Brown, 1970) where participants were shown to choose avoiding feelings of embarrassment over financial gains.
When an individual makes a social error, feelings of guilt or embarrassment changes not just the person’s mood but their body language.
There is a strong link between the ability of an individual to regulate their behaviour in an appropriate manner and problems with their self-conscious emotions.
While the findings are becoming more robust, the number of different variables involved will make it hard to ever come to a conclusion on the subject of poor behaviour being caused by these deficiencies.
The difficulty being the hardship of creating the proper environment within a lab where self-conscious emotions would not only occur, but could be adequately measured.
