Figure 2.
From left to right: female (0% male), relatively female (20% male), neutral (50% male), relatively male (80% male) and male (100% male). In a pilot study we asked participants (n = 15) to rate the gender of 9 different faces ranging from absolutely female to absolutely male (10 repetitions per face and presented in random order) in a 5-level scale (female/somehow female/cannot guess/somehow male/male). In order to achieve an s-shape psychometric curve, we selected the faces that best fit the 0%, 20%, 50%, 80% and 100% male.

Figure 4.
An example of a trial in experiment 1 (memorisation task).
This example shows an adaptation to female-associated objects, a male face as the test stimulus with no delay between the objects and the test face and a ‘new’ object for the subsequent old/new recognition task.
