Everyone has the right not to participate within the group, although it is usually preferable for all members to contribute.

Some members will prefer to observe rather than to participate vocally and others may wish to contribute but feel too shy, fear self-disclosure or lack confidence.  To overcome lack of self-confidence, where members wish to contribute but fear to do so, their non-participation needs an encouraging, positive approach, however, they should not be embarrassed or pressured to participate.

Some group members who are withdrawn may just take longer to warm to the group situation and to open up.  Over time, group members who were initially quite extrovert may listen more and say less, whilst those who said little initially may begin to say more, which will lead to more balanced contributions.
