Hi everyone! My name is Lauren and I am a master student fascinated by animal behaviour. The last six months I had the pleasure of working with Jolle and his three-spined sticklebacks at the University of Konstanz. I studied the effects of individual behavioural tendencies on group learning performance. Different group compositions were tested in a Y-maze to study group learning and reversal learning. I have learned a lot about individual tendencies and group dynamics by observing stickleback behaviour both during experiments and in their housing tanks.
