Identifying when a person is bored seems very simple. The outward signs are pretty obvious and well known.
You need to be careful, however, because the gestures for a person who is fatigued are almost the same as for one who is bored.
Here are some tips to separate the two concepts.
First of all, consider what is going on around the person. If this is hour three of a four-hour lecture on pollution containing hundreds of detailed PowerPoint slides, then when a person has his chin in his palm, it is likely out of boredom.
On the other hand, if a student is holding her head up with her hand, during a lively or funny class, you might want to inquire if she was up all night finishing her paper.
The Eyes
The big difference between fatigue and boredom is in the eyes. A bored person is usually sitting and staring out with a blank stare and heavy, but not closed, eyelids. A tired person usually will have her eyes shut or nearly shut.
If you see a person unable to maintain focus with her eyes, then suspect boredom as the cause. You may also observe a rolling of the eyes with boredom but not fatigue.
The Hands
The usual position of the hand is for one hand to be propping up the head. Occasionally you may see both hands doing this at the same time, but the predominant gesture is just with one hand.
A person experiencing extreme fatigue will often put his or her head down on the table rather than try to hold it up with a hand.
The Mouth
The telltale sign of a bored person is to yawn. Unfortunately, it is difficult to separate a yawn induced by boredom from one caused by being overtired. It is often the case that both fatigue and boredom may be occurring simultaneously.
It is interesting to observe how infectious yawning is. When a person sees another person yawn, it is common to see the first person yawn within about 10 seconds. You can observe yourself yawning shortly after observing another person doing it. You may even yawn immediately after seeing your dog do it, or vice versa.
General Posture
The most common forms of boredom occur when people are seated. People who are bored generally lean forward rather than backward. The opposite is often true for people who are fatigued.
Props
Look for fidgeting or doodling as another indication of boredom rather than fatigue. A tired person is trying to sleep, so there is no energy to play with a paperclip or make a paper airplane.
A person who is bored has some energy that is likely to come out in the form of interfacing with a handy object, like a pencil.
What to do
Usually teachers or those who facilitate group activities will see these kinds of gestures.
Obviously if many of the students are exhibiting these kinds of symptoms, you need to take note and call a break or an activity that will get people moving or engaged some other way.
With fatigue, you normally will see the reaction in only one or two people, while boredom can spread over an entire group.
Be alert for the problem and change your methods to keep people engaged. When their outward gestures are extreme enough to see, they are not listening to you anyway.

The gestures associated with pride seem simple enough, but you need to be careful because there are other emotions that can have similar features. In this article I will give some tips on how to spot true pride. 
A person experiencing pride will have a slight smile associated with a symmetrical pulling back of both cheeks. If only one cheek is pulled back then the smile is gone, and the gesture is probably that of contempt or distrust as opposed to pride.
The physical manifestations of doubt are pretty easy to spot. We have a special way of contorting our face and upper torso to convey the message.
One interesting gesture of body language between two people is when a listener holds his or her head up using both hands while at the same time looking directly at the speaker. Earlier in this series 
You have probably noticed someone, when in a listening mode, pinch the bridge of his or her nose. There are several possible meanings with this gesture, as with all body language signals. I will share the common meanings in this article.
In my article last week, I covered wringing of the hands. This week I want to make some general statements about hand gestures and discuss several of the ones that are of high interest to me.
When you think about it, the human hand is a remarkable instrument. We have amazing dexterity and control of motion that is not seen in any other species. I once saw a demonstration by a speaker who had no hands. In order to illustrate the impact, he had a member of the audience come up on stage. There was a bottle of water on the table. The speaker asked the man to take a drink of water. Without using his hands, it was impossible for the man to get the bottle open. Think about how you would attempt to do it.
Finger or foot tapping is another very well-known form of body language. The implication is almost always impatience.
This type of body language is very well known, and the meaning is hard to miss. Perhaps it is a bit more conscious than other BL gestures because we actually refer to it in daily conversation.
