4.2.6.2 Back channel support

The ratio of back channel items to the number of words in the discussion is low. G11 receives the most back channel items, but gives few (she receives 5 and gives 1). B9, on the other hand, gives the most (6) and receives the fewest (1). G12 gives no back channel support. This resembles the pattern noted in discussions I and III concerning the distribution of back channel support: the person who speaks most receives most back channel support items, and the speaker who gives most receives fewest. The table below shows the distribution of back channel support.

The relatively infrequent back channel support, and its unequal distribution, suggest a non-co- operative rather then a co-operative discussion.
