abstract = {The most consistent cognitive sex differences have been
found in the visuo-spatial domain, using Mental Rotation
(MR) tasks. Such sex differences have been suggested to bear
implications on our understanding of autism spectrum
disorders (ASD). However, it is still debated how the sex
difference in MR performance relates to differences between
individuals with ASD compared to typically developed control
persons (TD). To provide a detailed exploration of sex
differences in MR performance, we studied rotational
(indicated by slopes) and non-rotational aspects (indicated
by intercepts) of the MR task in TD individuals (total N =
50). Second-to-fourth digit length ratios (2D:4D) were
measured to investigate the associations between prenatal
testosterone and performance on MR tasks. Handedness was
assessed by the use of the Edinburgh Handedness Inventory in
order to examine the relation between handedness and MR
performance. In addition, we investigated the relation of
spatial to systemising abilities, both of which have been
associated with sex differences and with ASD, employing the
Intuitive Physics Test (IPT). Results showed a male
advantage in rotational aspects of the MR task, which
correlated with IPT results. These findings are in contrast
to the MR performance of individuals with ASD who have been
shown to outperform TD persons in the non-rotational aspects
of the MR task. These results suggest that the differences
in MR performance due to ASD are different from sex-related
differences in TD persons, in other words, ASD is not a
simple and continuous extension of the male cognitive
profile into the psychopathological range as the extreme
male brain hypothesis (EMB) of ASD would suggest.},
