Which animal sounds larger? (part 4)

Welcome and thank you for your interest!

About the study

Have you ever gone through a forest, heard some creature's voice in the bushes, and wondered how large it might be? We often form an impression of body size from the voice alone, and the aim of this study is to learn how this size estimation works.

Instructions

Find a quiet spot to do this experiment and use headphones if possible. The method is called the Implicit Associations Test. You are instructed to press the left arrow if you see a particular image or hear a particular sound, while another image and another sound require you to press the right arrow. These pairing rules change repeatedly.

NB: try to answer quickly, but not at the expense of accuracy - your main task is to answer correctly!
You need to score >75% correct (by memorizing and following the current rule) in order for your submission to be approved!
