3 Note that while the difference in mean amplitude is approaching significance, the pattern is such that female names are higher in amplitude, which leads to the opposite expectation of what was observed if amplitude were causing the results (i.e., higher amplitude was associated with spikiness, while female names were associated with roundness; Lacey et al. 2020 ). 4 The pattern is the same if age is treated as a dummy coded categorical variable for age in years, with 5‐year‐olds as the reference level.
