    "title": "Memory Capacity Limits in Processing of Natural Connected Speech:\nThe Psychological Reality of Intonation Units",
    "subtitle": null,
    "abstract": "Many theories of memory propose some type of short-\nterm store limited in capacity to a small number of in-\nformation chunks. However, although short-term ver-\nbal memory is generally considered to be a crucial\ncomponent of language processing, the relevant infor-\nmation chunk level that may de?ne capacity limits in\necologically-valid spoken language has never been inves-\ntigated. The Intonation Unit (IU), an intermediate-level\nprosodic phrase, has been theorized to be a fundamental\nunit of spoken language, the focus of a speaker's mental\nprocessing. This suggests that IUs might play a role as\nthe relevant unit representing \\chunks\" of spoken lan-\nguage. We report the results of an experiment investi-\ngating the role of IUs in short-term memory in a serial\nrecall task. We found a signi?cant non-linear e?ect of\nstimulus size in IUs, but not clauses. We conclude that\nIntonation Units are the primary linguistic unit used for\nchunking spoken language input in memory.",
