    "title": "Computational Exploration of Lexical Development in Down Syndrome",
    "subtitle": null,
    "abstract": "Research on lexical development in Down syndrome (DS) has\nemphasized a dissociation between language comprehension\nand production abilities, with production of words being\nrelatively more impaired than comprehension. Current\ntheories stress the role of associative learning on lexical\ndevelopment. However, there have been no attempts to\nexplain the atypical lexical development in DS based on\natypical associative learning. The long-term potentiation\n(LTP) and long-term depression (LTD) of synapses,\nunderlying associative learning, are altered in DS. Here we\npresent a neural network model that instantiates notions from\nneurophysiological studies to account for the disparities\nbetween lexical comprehension and production in DS. Our\nsimulations show that an atypical LTP/LTD balance affects\ncomprehension and production differently in an associative\nmodel of lexical development.",
