Three-dimensional computer graphic animations for studying social approach behaviour in medaka fish: Effects of systematic manipulation of morphological and motion cues
In experiment 1 (a), the effects of normal virtual medaka were compared with those of several static images of virtual medaka (Static, Grey scale/Static, Pressed/Static, and Pressed/Grey scale/Static groups) and blank (Blank group). In experiment 2 (b), two features of normal virtual medaka were changed, which resulted in the following five experimental groups: Grey scale/No locomotion, Grey scale/No body motion, Pressed/Grey scale, Pressed/No locomotion, and Pressed/No body motion. In experiment 3 (c), a single feature of normal virtual medaka was changed, which resulted in the following four experimental groups: Pressed, Grey scale, No locomotion, and No body motion. We analysed the time during which medaka were close to the display. All data are expressed as the means ± SD.
