The second experiment was designed in exactly the same way, but used a simpler discrimination task, in which 20 other participants were required to determine whether or not pairs of shapes they saw were the same or different colours.
We were able to rule out some alternative, lower level explanations through our design and additional tests (e.g. monkeys do not attend exclusively to one of the stimulus' edges, see electronic supplementary material, S1): testing primates in an operant setup could help exclude additional simpler discrimination strategies.

The authors describe several likely causes: differing amounts of experience (an explanation for 10% of the gap); occupational and industry differences (women are more likely to be in lower-paying service jobs) and simple discrimination (although this is hard to quantify).So why did the gender pay gap narrow in the 1980s and 1990s?
