Fig. 3From: Identifying and describing subtypes of spontaneous empathic facial expression production in autistic adultsClusters found in a ASD (N = 27) and b NT adults (N = 57). The ASD cluster analysis revealed a larger more stable cluster (cluster 1, n = 19) and a smaller, less stable cluster (cluster 2, n = 8). The NT cluster analysis revealed a larger more stable cluster (cluster 1, n = 39) and a smaller, less stable cluster (cluster 2, n = 18)Back to article page
