Background: There is an increasing recognition that the communication problems one observes in persons with aphasia extend beyond verbal deficits and that the myriad of symptoms observed are not solely due to a faulty linguistic system. Rather, there exists a coalition of causal elements resulting in a wide range of communicative deficits. There is some preliminary evidence suggesting that communicative success of clients with aphasia may depend on the integrity of executive function skills… Expand
Using a computer to communicate: Effect of executive function impairments in people with severe aphasia
Background : Some individuals with severe non-fluent aphasia do not respond in a functional way to any form of communication therapy. Others show improved ability to communicate with treatmentExpand
The relationship of language and attention in elders with nonfluent aphasia
Abstract Background: Researchers have questioned whether aphasia coincides with deficiencies in the non-linguistic executive functions needed to coordinate cognitive-linguistic skills. Attention, anExpand
Achieving conversational success in aphasia by focusing on non-linguistic cognitive skills: A potentially promising new approach
Background : Recent reports from a variety of labs have demonstrated that some patients with aphasia have concomitant non-linguistic cognitive compromises, especially in the area ofExpand
Executive function and conversational strategies in bilingual aphasia
Background: Deficits of executive function (EF) have been proposed as all or part of the underlying mechanisms of language impairment in at least some types of aphasia. Executive functions also playExpand
A specific pattern of executive dysfunctions in transcortical motor aphasia
Background: Recent studies imply that executive functions (EF) are closely related to our ability to comprehend and produce language. A number of findings suggest that functional communication andExpand
Executive function in aphasia: is there a bilingual advantage?

Executive functions in aphasia: A novel aphasia screening for cognitive flexibility in everyday communication
Good specificity and sensitivity are found and it is shown that the screening is correlated with language skills and verbal cognitive flexibility, revealing promising construct validity and feasibility of the new screening. Expand
Executive dysfunction as an explanatory basis for conversation symptoms of aphasia: A pilot study
Background: Lack of communicative success for people with aphasia is no longer seen as purely a linguistic deficit. Instead, the integrity of the executive functions (EF) is thought to be at leastExpand
The novel cognitive flexibility in aphasia therapy (CFAT): A combined treatment of aphasia and executive functions to improve communicative success
This pilot study indicates that CFAT offers a novel opportunity to directly train cognitive flexibility in communicative settings and complements conventional therapy for optimal patient outcome. Expand
Addressing concomitant executive dysfunction and aphasia: previous approaches and the new brain budget protocol
ABSTRACT Background: Findings from a number of researchers have suggested that many individuals with aphasia demonstrate concomitant, non-linguistic cognitive deficits, particularly affectingExpand


Memory Impairment and Executive Control in Individuals with Stroke-Induced Aphasia
Examination of memory abilities of aphasic individuals in relation to site of neurological lesion found stroke patients were impaired relative to control subjects on tests of verbal memory, and executive control deficits were postulated as explanatory of the LTM impairment associated with anterior lesions. Expand
Verbal memory function in mild aphasia
Persistent verbal-memory impairments accompanying even mild residual aphasia may be responsible for much of the difficulty mildly aphasic patients experience returning to vocational, academic, and social life. Expand
Disorders in executive control functions among aphasic and other brain-damaged patients.
The results suggest that aphasics' impairments in executive control are independent of their linguistic and visuospatial deficits and are specific to lesions in left frontal and prefrontal regions. Expand
Disturbances of long-term memory in aphasic patients. A comparison of anterior and posterior lesions.
The findings support a functional and neuroanatomical dissociation of short and long-term memory systems and suggest that neural connections of the inferior frontal lobe and the basal ganglia may be crucial for initiating the retrieval process. Expand
Auditory vigilance during divided task attention in aphasic individuals
Abstract Little research has been reported on auditory vigilance skills of aphasic individuals, particularly under a dual task paradigm designed to divide attention. Six aphasic males and six genderExpand
Assessment of executive functions in clinical settings: problems and recommendations.
In this article we provide a tutorial review of various theoretical issues that surround executive function research from the perspective of cognitive psychology, focusing on issues that haveExpand
Memory and aphasia
Both brain-damaged groups were significantly impaired in all memory tasks (except for chronic patients in the story learning task) compared to normal controls, and chronic patients performed significantly better than acute patients only in the Corsi's learning task. Expand

An information-processing model is outlined that predicts that performance on non-routine tasks can be impaired independently of performance on routine tasks. The model is related to views on frontalExpand
Frontal lobe and frontal-striatal substrates for different forms of human cognitive flexibility
It is suggested that the frontal lobe and basal ganglia participate differently in the neural substrate of cognitive flexibility, as the corticostriate system appears to mediate reactive flexibility, which may require direct cortical-cortical interactions byThe frontal lobe in order to access knowledge systems with novel strategies that transcend the most common semantic linkages.

Working memory: a foundation for executive abilities and higher-order cognitive skills.
An overview of three prominent models of working memory is provided with experimental support for each and future directions for the development of both theory and assessment tools are offered. Expand
