“…Results of previous studies indicate that increased attention demands of dual-task conditions tend to impact language comprehension (Blackwell & Bates, 1995; Granier, Robin, Shapiro, Peach, and Zimba, 2000; King & Hux, 1996; LaPointe & Erickson, 1991; McNeil, Matthews, Hula, Doyle, & Fossett, 2006; McNeil et al, 2005; Murray, Holland, & Beeson, 1997; Tseng, McNeil, & Milenkovic, 1993) and production (Hula, McNeil, & Sung, 2007; Murray, 2000) in people with and without aphasia.…”

“…Attention allocation, the process of allotting attention to a given task in the face of competing tasks and complex or multiple stimuli to be processed, is of particular concern in people with aphasia. Attention limitations are generally considered to contribute to language comprehension deficits (Hula & McNeil, 2008; LaPointe & Erickson, 1991; McNeil et al, 2004, 2005; Murray, Holland, & Beeson, 1997; Robin & Rizzo, 1988). An increase in task demands requires more attention resources (Murray, 1999); that is, it requires greater cognitive effort, and taxes a finite capacity.…”

“…Reduced accuracy and slower reaction times during the dual-task condition are interpreted to reflect resource allocation problems or limited capacity resources due to increased task demands. People without aphasia tend to exhibit a decrease in performance on dual tasks when compared to single tasks in terms of accuracy and response time (Blackwell & Bates, 1995; Granier et al, 2000; Hula, McNeil, & Sung, 2007; McNeil et al, 2004, 2005; Tseng et al, 1993). In studies including individuals with and without aphasia, those with aphasia tended to demonstrate greater decrements in performance compared to control participants on dual tasks (King & Hux, 1996; LaPointe & Erickson, 1991; Murray, 2000, 2012; Murray, Holland, & Beeson, 1997, 1998).…”

“…For example, Tseng et al (1993) modified the probability of occurrence of phonetic and semantic target stimuli while participants identified semantic targets, phonetic targets, or both; Blackwell and Bates (1995) modified the length of digit sequences to be recognized while participants judged grammaticality of sentences; McNeil et al (2004, 2005, 2006) manipulated the complexity of stories to be remembered and for later retelling while participants carried out a manual tracking task. When complexity is increased, decreases in speed and accuracy tend to be observed in people with and without aphasia; these decrements, too, are attributed to an attention resource shortage or allocation inefficiency.…”

“…Examples of response execution in dual-task conditions to date include: (a) selecting and pressing a computer keyboard key (Murray et al, 1997, 1998, Tseng et al, 1993), (b) speaking (King & Hux, 1996), (c) gesturing or raising ones’ hand when hearing a target word (LaPointe & Erickson, 1991), and (d) continuous manipulation of a joystick or computer mouse during motor tracking (Granier et al, 2000; McNeil et al, 2005, 2006). Requisite eye-hand coordination, visual-spatial orientation, motor planning, and fine motor skills, are commonly affected by brain injury.…”

Numerous authors report that people with aphasia have greater difficulty allocating attention than people without neurological disorders. Studying how attention deficits contribute to language deficits is important. However, existing methods for indexing attention allocation in people with aphasia pose serious methodological challenges. Eye-tracking methods have great potential to address such challenges. We developed and assessed the validity of a new dual-task method incorporating eye tracking to assess attention allocation. Twenty-six adults with aphasia and 33 control participants completed auditory sentence comprehension and visual search tasks. To test whether the new method validly indexes well-documented patterns in attention allocation, demands were manipulated by varying task complexity in single- and dual-task conditions. Differences in attention allocation were indexed via eye-tracking measures. For all participants significant increases in attention allocation demands were observed from single- to dual-task conditions and from simple to complex stimuli. Individuals with aphasia had greater difficulty allocating attention with greater task demands. Relationships between eye-tracking indices of comprehension during single and dual tasks and standardized testing were examined. Results support the validity of the novel eye-tracking method for assessing attention allocation in people with and without aphasia. Clinical and research implications are discussed.

Purpose: Arousal and cognitive effort are relevant yet often overlooked components of attention during language processing. Pupillometry can be used to provide a psychophysiological index of arousal and cognitive effort. Given that much is unknown regarding the relationship between cognition and language deficits seen in people with aphasia (PWA), pupillometry may be uniquely suited to explore those relationships. The purpose of this study was to examine arousal and the time course of the allocation of cognitive effort related to sentence processing in people with and without aphasia. Method: Nineteen PWA and age- and education-matched control participants listened to relatively easy (subject-relative) and relatively difficult (object-relative) sentences and were required to answer occasional comprehension questions. Tonic and phasic pupillary responses were used to index arousal and the unfolding of cognitive effort, respectively, while sentences were processed. Group differences in tonic and phasic responses were examined. Results: Group differences were observed for both tonic and phasic responses. PWA exhibited greater overall arousal throughout the task compared with controls, as evidenced by larger tonic pupil responses. Controls exhibited more effort (greater phasic responses) for difficult compared with easy sentences; PWA did not. Group differences in phasic responses were apparent during end-of-sentence and postsentence time windows. Conclusions: Results indicate that the attentional state of PWA in this study was not consistently supportive of adequate task engagement. PWA in our sample may have relatively limited attentional capacity or may have challenges with allocating existing capacity in ways that support adequate task engagement and performance. This work adds to the body of evidence supporting the validity of pupillometric tasks for the study of aphasia and contributes to a better understanding of the nature of language deficits in aphasia.
