Yet, the STS is a heterogeneous structure containing unique subregions, such as the superior temporal asymmetrical pit (STAP), which is a recently identified human-specific landmark. To date, no study has compared the STAP between ASD individuals and neurotypical controls (NTs) in a large sample. Here, we analyzed the mean intra-hemispheric sulcal depth and inter-hemispheric laterality of the STAP, as well as the anterior and posterior portions of the STS (aSTS, pSTS), in 100 NTs and 100 ASD male individuals (ages 5-18) using a discovery-replication design. Across samples, the STAP and pSTS showed rightward asymmetry, while the aSTS showed leftward asymmetry within groups. All features of the STAP, aSTS, or pSTS did not differ significantly between groups. However, pSTS laterality related to individual differences in social cognition, which was further supported by a meta-analysis across over 200 studies showing that neurocognitive functional differences associated with social cognition and ASD are restricted to portions of the STS outside of the STAP. Together, these findings provide fine-grained insight into prior studies showing coarse morphological differences of the STS between individuals with ASD and NTs, as well as open up new questions and new neuroanatomical targets of the heterogeneous STS in future studies of brain structure, brain function, and cognition in ASD, as well as other neurodevelopmental disorders targeting the superior temporal cortex.<\/jats:p>\n                <jats:sec>\n                  <jats:title>Lay Summary<\/jats:title>\n                  <jats:p>Here, we show that a recently identified human-specific landmark within the superior temporal sulcus, a common target in ASD research, is comparable between ASD individuals and neurotypical controls. Yet, laterality metrics outside of this human-specific landmark correlate with individual differences in social cognition, which aligns with meta-analyses across hundreds of studies. These findings provide new neuroanatomical targets within the heterogeneous superior temporal cortex for future studies not only in ASD, but also other neurodevelopmental disorders.<\/jats:p>\n
