Measures of preference when applying the partner preference test across different types of relationships in Experiments 1 and 2. (a) Only in the case of a current partner did test animals spend a greater proportion of time in the preference zone of the familiar stimulus animal compared to the stranger. (b) In the case of a former infant attachment to the father, test animals displayed a trend to spend a greater proportion of time touching the grated window of the familiar compared to the stranger stimulus animals. (c) Test animals chose the familiar stimulus animal more frequently when tested with their current partner compared to when they were tested with their mother or father. Test animals also chose the stranger less frequently when tested with their current partner compared to when they were tested with their mother or father. ** P < 0.01; * P < 0.05. # P=0.07.
