Record keeping in two types of relationships.

On the basis of a distinction between communal and exchange relationships (Clark Mills & Clark, 1982), the following predictions were made: (a) Members of exchange relationships would keep track of individual inputs into joint tasks and (b) members of communal relationships would not. These hypotheses were tested in three studies. In each study, subjects worked on a task with a partner with whom they (a) desired or had a communal relationship or (b) desired or had an exchange relationship. The task involved locating and circling number sequences in a large matrix. Whether subjects used a pen of the same or of a different color from that used by their partner served as the dependent measure. If partners worked with pens of the same color individual inputs wee obscured. If they worked with different color pens, individual inputs were clear. Given this, if the proportion of subjects in a condition choosing different color pens was greater than 50% (chance), it was taken as evidence that subjects in that condition were trying to keep track of individual inputs. If this proportion was less than 50%, it was taken as evidence that subjects were trying to avoid keeping track of individual inputs. As predicted, in all three studies the proportion of subjects in the exchange conditions who chose a different color pen was significantly greater than 50% and was significantly greater than the proportion of subjects in the communal conditions who chose a different color pen. Also as expected, in no study was this percentage greater than 50% in he communal conditions.(ABSTRACT TRUNCATED AT 250 WORDS)
