Individuals repeatedly receiving a stimulus without harm become habituated to it. However, few studies have been conducted on individual and sexual differences in the process of habituation to unfamiliar food stimuli. Therefore, we hypothesized that individual differences or sexual differences would be observed in reaction to an in-lab food-stimuli presentation of potential prey items (after that "food stimuli"). We tested the hypothesis using the Japanese tree frog Hyla japonica, and conducted statistical analyses of these results. A generalized linear model (GLM) showed individual and sexual differences in time to get used to the food stimuli. Females habituated more rapidly to food stimuli than males. The difference between sexes is discussed in view of two ultimate and one proximate reasons. en-copyright= kn-copyright= en-aut-name=TanabeShintaro en-aut-sei=Tanabe en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KasuyaEiiti en-aut-sei=Kasuya en-aut-mei=Eiiti kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Biology, Faculty of Sciences, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil= en-keyword=Habituation kn-keyword=Habituation en-keyword=Hyla japonica kn-keyword=Hyla japonica en-keyword=individual variation kn-keyword=individual variation en-keyword=sexual difference kn-keyword=sexual difference en-keyword=predation kn-keyword=predation END
