Response distribution network of the ASD group. Photographical nodes in the network represent the 43 target words; word-form nodes in the network represent the source words; edges between these nodes represent the relationship of participants' choices between target words and source words: The more times that a word was chosen by participants, the thicker the edge. Density is the actual connections divided by potential connections (all possible connections) in network. In the present study, there were 5 possible answers (i.e., 5 nodes) and 10 potential connections for a given item. If no actual connection exits, density is zero; In-degree is an item-based measure that counts connections from all nodes (all possible answers) to a particular node (the correct answer)
