Richardson, Kelly C.; Sussman, Joan E. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The purpose of the current study was to examine sensory and auditory memory limitations on intensity resolution in individuals with Parkinson's disease as compared to healthy older and younger adults. Method: Nineteen individuals with Parkinson's disease, 10 healthy age- and hearing-matched adults, and 10 healthy young adults were…

Riffo, Bernardo; Guerra, Ernesto; Rojas, Carlos; Novoa, Abraham; Veliz, Mónica – Journal of Psycholinguistic Research, 2020
The association between a word and typical location (e.g., cloud-up) appears to modulate healthy individuals' response times and visual attention. This study examined whether similar effects can be observed in a clinical population characterized by difficulties in both spatial representation and lexical processing. In an eye-tracking experiment,…

Thompson, Megan R.; Stone, Ramona F.; Ochs, V. Dan; Litvan, Irene – Educational Gerontology, 2013
In order to determine primary health care providers' (PCPs) knowledge gaps on Parkinson's disease, data were collected before and after a one-hour continuing medical education (CME) lecture on early Parkinson's disease recognition and treatment from a sample of 104 PCPs participating at an annual meeting. The main outcome measure was the…

Lam, Jennifer; Tjaden, Kris – Journal of Speech, Language, and Hearing Research, 2016
Purpose: The authors investigated how different variants of clear speech affect segmental and suprasegmental acoustic measures of speech in speakers with Parkinson's disease and a healthy control group. Method: A total of 14 participants with Parkinson's disease and 14 control participants served as speakers. Each speaker produced 18 different…

Monroe, Penelope; Halaki, Mark; Kumfor, Fiona; Ballard, Kirrie J. – International Journal of Language & Communication Disorders, 2020
Background: Acquired brain injury (ABI), such as Parkinson's disease, dementia or stroke, can result in communication difficulties that lead to an impoverished ability to connect meaningfully with others. Choral singing is a complex task that uses multiple brain regions which are also responsible for language and communication skills. The…

Whitfield, Jason A.; Kriegel, Zoe; Fullenkamp, Adam M.; Mehta, Daryush D. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and…

Chiu, Yi-Fang; Neel, Amy; Loux, Travis – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Auditory perceptual judgments are commonly used to diagnose dysarthria and assess treatment progress. The purpose of the study was to examine the acoustic underpinnings of perceptual speech abnormalities in individuals with Parkinson's disease (PD). Method: Auditory perceptual judgments were obtained from sentences produced by 13 speakers…

Senthinathan, Anita; Adams, Scott; Page, Allyson D.; Jog, Mandar – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Hypophonia (low speech intensity) is the most common speech symptom experienced by individuals with Parkinson's disease (IWPD). Previous research suggests that, in IWPD, there may be abnormal integration of sensory information for motor production of speech intensity. In the current study, intensity of auditory feedback was systematically…

Knowles, Thea; Adams, Scott G.; Jog, Mandar – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The aim of this study was to quantify changes in speech intelligibility in two cohorts of people with Parkinson's disease (PD; those with and without deep brain stimulation [DBS]) across a broad range of self-selected speech rate alterations in: (1) read sentences; and (2) extemporaneous speech (monologues). Method: Four speaker groups…

De Groote, Evelien; Bockstael, Annelies; Botteldooren, Dick; Santens, Patrick; De Letter, Miet – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Several studies have demonstrated increased auditory thresholds in patients with Parkinson's disease (PD) based on subjective tonal audiometry. However, the pathophysiological mechanisms underlying auditory dysfunction in PD remain elusive. The primary aim of this study was to investigate cochlear and olivocochlear function in PD using…

Whitfield, Jason A.; Mehta, Daryush D. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The purpose of the current study was to characterize clear speech production for speakers with and without Parkinson disease (PD) using several measures of working vowel space computed from frequently sampled formant trajectories. Method: The 1st 2 formant frequencies were tracked for a reading passage that was produced using habitual and…

Abur, Defne; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Given the role of auditory perception in voice production, studies have investigated whether impairments in auditory perception may underlie the noted disruptions in speech in Parkinson's disease (PD). Studies of loudness perception in PD show impairments in the perception of self-generated speech, but not external tones. Studies of pitch…

Chiu, Yi-Fang; Neel, Amy – Journal of Speech, Language, and Hearing Research, 2020
Purpose: This study investigated whether perceptual ratings of speech parameters were predictive of transcription intelligibility in quiet and in noise for speakers with Parkinson's disease (PD). Method: Ten speakers with PD and five healthy controls read 56 sentences. One group of 60 listeners orthographically transcribed the sentences in quiet,…

Smith, Sarah K.; Roddam, Hazel; Sheldrick, Heulwen – International Journal of Language & Communication Disorders, 2012
Background: Dysphagia is a common symptom of Parkinson's disease and can have negative consequences for physical health and quality of life. A variety of treatment options are available to clinicians working with people who have dysphagia and Parkinson's disease. These options can be broadly categorized as being compensatory or rehabilitative in…

Basirat, Anahita; Moreau, Caroline; Knutsen, Dominique – International Journal of Language & Communication Disorders, 2021
Background: Parkinson's disease (PD) leads to changes in verbal communications. The focus of most studies to date has been on speech impairment, which is specifically referred to as dysarthria. Although these studies are crucial to understanding the impact of PD on verbal communication, they do not focus on the features of dialogues between people…
