Preliminary Observations on Play Behavior in Puppies

Previous research suggested that the experimenter variable in conservation assessment procedures has not been adequately studied. This experiment investigated the effect of sex of experimenter on length conservation responses in second-grade subjects under group testing procedures. Results of contingency table analysis of observed frequencies suggested that there are significantly more operational conservers under female test administration than under male test administration. Further analysis revealed no significant difference in the number of operational conservers for male and female Ss with either male or female examiners. The sex of experimenter variable does appear to be an important factor in conservation assessment at the lower elementary level.
