コンピュータビジョンを用いた社会オペラント行動の計測に向けてのこれまでの歩み

Operant conditioning has not been well adapted to social behavior despite a growing interest among behavior analysts. This is due in part to technological limitations in measuring social behavior, especially in real time. This paper presents a summary of three of the present author􀊟s attempts to adapt computer vision technologies to the study of social operant behavior of zebrafish (Danio rerio). Experiment 1 examined whether the location of a single zebrafish in a three-dimensional (3D) space could be tracked in real time. In Experiment 2, locations of two zebrafish were tracked simultaneously. A transparent partition was placed between the two fish to aid in their identification. A food reinforcer was delivered when the two fish approached one another across the partition. Experiment 3 examined whether it is possible to track multiple fish without such a partition. Results of these three experiments were promising, suggesting that computer vision can be useful in the study of social operant behavior. [ABSTRACT FROM AUTHOR]
