Utterly worthless study
Comments on 3 different videos each of a different robot and three different humans. This has no statistical power at all and makes only the most pathetic attempt to control for the huge number of factors which will affect responses that are nothing to do with the hypothesis they are supposed to be testing ('similar videos'). That would be bad enough with an experiment design which would be rejected as hopelessly naive and incompotent for a school child but they then make comments about the impact of gender in a study with only a single gender and no way of performing any sort of comparison!
Everyone involved has damaged their reputation.
It is the sort of fundamentally broken experiment you expect from a gender studies department not an engineering department like computer science.
