Cognitive constraints on advance planning of sentence intonation

ABSTRACT: Pitch peaks tend to be higher at the beginning of longer than shorter sentences (e.g., ‘A farmer is pulling donkeys’ vs ‘A farmer is pulling a donkey and goat’), whereas pitch valleys at the ends of sentences are rather constant for a given speaker. These data seem to imply that speakers avoid dropping their voice pitch too low by planning the height of sentence-initial pitch peaks prior to speaking. However, the length effect on sentence-initial pitch peaks appears to vary across different types of sentences, speakers and languages. Therefore, the notion that speakers plan sentence intonation in advance due to the limitations in low voice pitch leaves part of the data unexplained. Consequently, this study suggests a complementary cognitive account of length-dependent pitch scaling. In particular, it proposes that the sentence-initial pitch raise in long sentences is related to high demands on mental resources during the early stages of sentence planning. To tap into the cognitive underpinnings of planning sentence intonation, this study adopts the methodology of recording eye movements during a picture description task, as the eye movements are the established approximation of the real-time planning processes. Measures of voice pitch (Fundamental Frequency) and incrementality (eye movements) are used to examine the relationship between (verbal) working memory (WM), incrementality of sentence planning and the height of sentence-initial pitch peaks.

Project description:Background/objectiveAdvance care planning (ACP) is associated with improved patient and caregiver outcomes, but is underutilized. To encourage ACP, the Centers for Medicare & Medicaid Services implemented specific ACP visit reimbursement codes in 2016. To better understand the utilization of these ACP reimbursement codes, we explored regional variation in billed ACP visits.DesignWe performed a retrospective cross-sectional analysis using a randomly sampled 5% cohort of Medicare fee-for-service (FFS) beneficiaries' claims files from 2017. Region was defined by hospital referral region.SettingNational Medicare FFS.ParticipantsA total of 1.3 million Medicare beneficiaries aged 65 years and older.MeasurementReceipt of billed ACP service, identified through Current Procedural Terminology code 99497 or 99498. Proportion of beneficiaries who received billed ACP service(s) by region was calculated. We fit a multilevel logistic regression model with a random regional intercept to determine the variation in billed ACP visits attributable to the region after accounting for patient (demographics, comorbidities, and medical care utilization) and regional factors (hospital size, emergency department visits, hospice utilization, and costs).ResultsThe study population included about 1.3 million beneficiaries, of which 32,137 (2.4%) had at least one billed ACP visit in 2017. There was substantial regional variation in the percentage of beneficiaries with billed ACP visits: lowest quintile region, less than 0.83%; subsequent regions, less than 1.6%, less than 2.4%, less than 3.3% to less than 8.4% in the highest quintile regions. A total of 15.4% of the variance in whether an older adult had a billed ACP visit was explained by the region. Although numerous regional factors were associated with billed ACP visits, none were strong predictors.ConclusionIn 2017, we found wide regional variation in the use of billed ACP visits, although use overall was low in all regions. Increasing the understanding of the drivers and the effects of billed ACP visits could inform strategies for increasing ACP.
