title: Erratum to: Rats demonstrate helping behavior toward a soaked conspecific.
abstract: Erratum to: Anim CognDOI 10.1007/s10071-015-0872-2. The authors would like to correct the word "less" to "more" in the sentence under the heading "Results and discussion". The correct sentence should read as: This indicates that the soaked rats spent more time in the pool area than did the helper rats.
