PURPOSE The goal of this study was to evaluate aspects of the functional distance hypothesis, which predicts that tasks regulated by brain networks in closer anatomic proximity will interfere more with each other than tasks controlled by spatially distant regions. Speech, verbal fluency, and manual motor tasks were examined to ascertain whether right-handed activity would interfere more with speech and language performance because of the presumed greater demands on the left hemisphere.

Cognitive Load Affects Speech Motor Performance Differently in Older and Younger Adults.

Increased cognitive load involving response inhibition, selective attention, and working memory processes within a speech production task disrupted both the stability and timing with which speech was produced by both age groups.

Effects of Concurrent Manual Task Performance on Connected Speech Acoustics in Individuals With Parkinson Disease.

There were little to no changes in speech production when a low-demand oscillatory motor task was performed with concurrent reading and for the extemporaneous task, however, individuals with PD exhibited significant changes when the speech and manual tasks were performed concurrently, a pattern that was not observed for control speakers.

Bidirectional Interference Between Speech and Nonspeech Tasks in Younger, Middle-Aged, and Older Adults.

The results increase what is known about bidirectional interference between speech and other concurrent tasks as well as age effects on speech motor control.

Speech Motor Sequence Learning: Effect of Parkinson Disease and Normal Aging on Dual-Task Performance.

Data suggest that PD affects the later stages of speech motor learning, as the dual-task condition interfered with production of the recently learned sequence beyond the effect of normal aging.

Individual differences in auditory-motor integration revealed by speech fluency manipulations

A role for auditory feedback in maintaining fluency appears less specific than for pitch control, as one example, but delayed auditory feedback (DAF) clearly provides a potent manipulation of


Speaking while doing another task is frequent in everyday life. While the effect of speaking on performing another task has been often studied, little is known on the effect of dual-task on speech,

Effects of Syntactic Complexity on Speech Motor Performance

Effects of Syntactic Complexity on Speech Motor Performance Kelsey L Boyce Department of Communication Disorders Master of Science This study evaluated the possible influence of linguistic demands on



Effects of concurrent motor, linguistic, or cognitive tasks on speech motor performance.

Findings show that distractor tasks during speech can have a significant influence on several labial kinematic measures, which suggests that the balance of neural resources allocated to different aspects of human communication may shift according to situational demands.

The findings reveal that speech motor activity can influence linguistic performance as well as be influenced by it, and suggest that clinicians working with disordered speakers should not overlook the potential interactions among the demands of language formulation, cognitive activity, and speech motor performance.

The Effect of a Concurrent Task on Parkinsonian Speech

It is suggested that speech and skeletal movement control are similarly driven by the higher-order frontostriatal impairment inherent in PD.

Dividing attention between the hands and the head: Performance trade-offs between rapid finger tapping and verbal memory.

We tested a multiple resources approach to time-sharing performance which assumes that each cerebral hemisphere controls its own set of processing resources that it cannot share with the other

Temporary interference in human lateral premotor cortex suggests dominance for the selection of movements. A study using transcranial magnetic stimulation.

It is concluded that the premotor cortex is important for selecting movements after a visual cue and that the left hemisphere is dominant for the rapid selection of action.

The dual task paradigm: Speech dominance or manual dominance?

Neural representations of skilled movement.

Stroke patients with ideomotor limb apraxia who had damage lateralized to a left hemispheric network involving the middle frontal gyrus and intraparietal sulcus region revealed that discrete areas in the left hemisphere of humans are critical for control of complex goal-directed movements.

Activation of right insular cortex during imaginary speech articulation

The current magnetoencephalography study, in which 12 participants were required to imagine vocalizing a phonogram after a visual cue, was designed to visualize the prearticulatory ‘automatic’ processes corresponding to the motor initiation, suggesting that motor control of speech proceeds from the insular regions.
