Behavioral responses to novelty in mice: a reanalysis.

A recently proposed searching procedure for scale transformations and models was applied to previously obtained data on rearing responses and locomotor activity in mice from two inbred selection lines (SRH and SRL) and four hybrid generations. Logarithmic transformation provided the most appropriate scale of measurement for both behaviors. For rearing, the simple additive model was adequate, thus validating the earlier findings. However, contrary to the previous conclusions, an additivity-dominance model fitted the locomotion data best. These results demonstrate the usefulness of the procedure described.
