Fish are curious about new numbers (VIDEO)
Caption
The video shows experiments described in the lab of Prof Vallortigara and reported in Messina et al (2022). On the left side an example is shown of the procedure of habituation of a zebrafish to a certain numerosity; on the right side one can notice that during the dishabituation test when the numerosity is abruptly changed the zebrafish exhibit increased stay close to the stimulus to explore the novelty. Controls showed that zebrafish responded to numerosity as such and not just to change in area or spatial positions of the dots.
