Further Evidence of Auditory Extinction in Aphasia

Abstract

Results indicate that, for IWA, auditory extinction may not be attributed to a binding deficit or inefficient attention resource allocation because of equivalent performance across all 5 conditions. Rather, overall attentional resources may be influential. Future research in aphasia should explore the effect of the stimulus presentation in addition to the continued study of attention treatment.

Attention to attention in aphasia – elucidating impairment patterns, modality differences and neural correlates

“…That study reported slower and less accurate responses, at the group-level, to auditory stimuli in more complex tasks. In other previous investigations reporting difficulties in tests with auditory stimuli ( Erickson et al, 1996 ; LaCroix et al, 2021 ; Laures, 2005 ; Shisler Marshall et al, 2013 ), only responses to auditory stimuli were collected, hence no comparison between auditory and other sensory modalities can be made. Critically, poorer performance when reacting to auditory compared to visual stimuli might be attributable to differences in task difficulty or other task characteristics that are confounded with the modality.…”

“…A few studies have specifically investigated aspects of attention in individuals with aphasia (for a review see also Villard & Kiran, 2017 ). Most of this research focused on the processing of auditory stimuli and reported impairments in basic ( Laures, 2005 ; Shisler Marshall, Basilakos, & Love-Myers, 2013 ) or more complex auditory attention tests ( Kuptsova, Dragoy, & Ivanova, 2021 ; LaCroix, Baxter, & Rogalsky, 2020 ) as well as in situations where multiple stimuli must be attended at the same time ( Erickson, Goldinger, & LaPointe, 1996 ). Other recent studies used visual tasks ( LaCroix, Tully, & Rogalsky, 2021 ; Lee, Kocherginsky, & Cherney, 2020 ) and/or focused on the variabiltiy of reaction times ( Naranjo, Grande, & Alted, 2018 ; Villard & Kiran, 2015 , 2018 ), finding inter-individual differences and some associations with language performance.…”

“…Taken together, previous research suggests that there are various levels of attentional difficulties in patients with aphasia. However, previous investigations have often only considered one specific task ( Erickson et al, 1996 ; LaCroix et al, 2020 ; LaCroix et al, 2021 ; Laures, 2005 ; Lee et al, 2020 ; Naranjo et al, 2018 ), stimulus modality ( Erickson et al, 1996 ; LaCroix et al, 2020 ; LaCroix et al, 2021 ; Laures, 2005 ; Lee et al, 2020 ; Naranjo et al, 2018 ; Shisler Marshall et al, 2013 ), and/or type of measure ( Erickson et al, 1996 ; Shisler Marshall et al, 2013 ). Also, often only group-level analyses ( Erickson et al, 1996 ; LaCroix et al, 2020 ; LaCroix et al, 2021 ; Laures, 2005 ; Naranjo et al, 2018 ; Shisler Marshall et al, 2013 ; Villard & Kiran, 2015 , 2018 ) and/or data based on experimental tasks ( Erickson et al, 1996 ; Laures, 2005 ; Shisler Marshall et al, 2013 ; Villard & Kiran, 2015 , 2018 ) were presented.…”

The handful of more thorough investigations including standardised neuropsychological tests either contained very limited information on the aspect of speed ( Murray, 2012 ) or collapsed performance across modalities ( Schumacher et al, 2019 ; Spaccavento et al, 2019 ).…”

Effects of Acquired Aphasia on the Recognition of Speech Under Energetic and Informational Masking Conditions

“…The converse of this phenomenonright neglect in individuals with left-hemisphere damage and aphasia-is less common (Beis et al, 2004). However, despite this, a number of studies have noted some degree of decreased attention to stimuli presented on the right in PWA (Bouma & Ansink, 1988;Ihori, Kashiwagi, & Kashiwagi, 2015;Marshall, Basilakos, & Love-Myers, 2013;Petry, Crosson, Rothi, Bauer, & Schauer, 1994;Shisler, 2005).…”
