Figure 1.
Heuristic diagram of the significant interaction effect of ‘short-term mating strategy’ and ‘early onset of sexual activity’ on ‘timing of childbearing.’
End points calculated using 25th and 75th percentiles for ‘early onset of sexual activity’ and ‘short-term mating strategy,’ with educational attainment at the median (upper high school).
Figure 2.
Heuristic diagram of the significant interaction effect of ‘short-term mating strategy’ and ‘reproductive output’ on average duration of breastfeeding per child (in months).
End points calculated using 25th and 75th percentiles for ‘reproductive output’ and ‘short-term mating strategy,’ with educational attainment at the median (upper high school), age at the mean (64.44 years) and ‘timing of childbearing’ at the mean.
