Language of closure
Closure literally closes the body up. It may range from a slight bringing together of the limbs to curled up into a tight ball. Extreme cases may also include rhythmic rocking of the body to and fro.
In a closed positions one or both arms cross the central line of the body. They may be folded or tightly clasped or holding one another. There may also be holding one another.
Lighter arm crossing may include resting an arm on a table or leg, or loosely crossed with wrists crossing.
Varying levels of tension may be seen in the arms and shoulders, from a relaxed droop to tight tension and holding on to the body or other arms.
Legs, likewise can be crossed. There are several styles of leg crossing, including the ankle cross, the knee cross, the figure-four (ankle on opposite knee) and the tense wrap-around.
Legs may also wrap around convenient other objects, such as chair legs.
When legs are crossed but arms are not, it can show deliberate attempts to appear relaxed. This is particularly true when legs are hidden under a table.
Looking down or away
The head may be inclined away from the person, and particularly may be tucked down.
