The first column indicates the looked-for BCT. The diagonal shows the percentage of specific pointing (stimuli identified as only belonging to one BCT, indicated in the first column). Other values indicate the percentage of non-specific pointing (stimuli identified as belonging to multiple BCTs). Only percentages over 3% are shown. The BCT pairs with a mean link (shared use) higher than 10% (average between both directions of the pair, e.g., Green-Brown 21.03 and Brown-Green 26.35, mean shared use is 23.69%) are in bold. The number of asterisks indicates the strength of the link for the three least discriminable BCT pairs (more asterisks, less discriminability).
