I would like to go over discussing this, so I can better understand it:
(bold added)as a role (3rd) function (LSE and LIE)
The individual makes an effort to adapt to the prevailing emotional atmosphere, especially in group situations, and tries to promote a positive emotional environment, as in making positive or witty remarks, in the presence of individuals he is already somewhat acquainted with and appreciates. Such efforts, however, are normally low-key and of short duration; it is difficult for him to display emotions more complex or intense than enthusiasm. He is essentially unable to participate in a group atmosphere where intense emotional expression as in loud laughing and mutual jokes are prevailing. The individual makes an effort to be aware of the need not to disrupt the prevailing emotional atmosphere but he does not succeed for any length of time if that would clash with his inner emotional state and private feelings about the other persons present. A typical example is the person who, in a group of people exchanging pleasantries and casual conversation, will occasionally correct erroneous statements made by others, in a way that can be perceived as annoying, despite otherwise making an effort to abide by the prevailing emotional atmosphere.
Particularly I am interested in talking about the bold sentences.
