Illustration of two trials out of the target detection paradigm.
Fig 2.
Example for a parametrically manipulated baby.
From left to right: low BS condition, unmanipulated baby picture and high BS condition.
Fig 3.
Mean reaction times in ms to select the infant or the adult target (± SEM).
* p < 0.05, paired t-test, one-tailed.
Fig 4.
Negative correlation between salivary testosterone concentration and selective attention to human infant portraits (r = -0.402, p = 0.04, one-tailed).
Fig 5.
In both figures, the mean reaction times to select an adult or an infant target are shown for both administration conditions (oxytocin or placebo) (± SEM).
The reaction times to select an infant target are shown for the three baby schema conditions: minus = low BS, neutral = unmanipulated BS, plus = high BS. On the left side you can see the results for women with low T concentrations (nlowT = 19) and on the right side you can see the results for women with high T concentrations (nhighT = 19). Not significant = n.s., * = p < 0.05, t-test, one-tailed.

Negative correlation between salivary testosterone concentration and selective attention to human infant portraits (r = -0.394, p = 0.007; one-tailed).
