Open field test: The study authors state that hand scored items were performed by a blinded observer (++ for blinding). Other endpoints in the open field test were digitally recorded and analyzed using TopScan tracking software. The test apparatus was described, but not in great detail (+ for methods; + overall).

Novel social test: The study authors report that endpoints were scored by a blinded observer and movements were recorded digitally and analyzed by TopScan software (++ for blinding). The test apparatus is described in a separate reference and endpoint collection was described in moderate detail (+ for methods; + overall).

Partner preference test: The test setting was adequately described and methods seem appropriate (+ for methods). Preference was assessed by time spent together or in contact which was recorded digitally and analyzed using TopScan tracking software (+ for blinding; + overall).
