Links between Short-Term Memory and Word Retrieval in Aphasia
… task: individuals listen to a list of digits or words and repeat them immediately after the list ends. People with aphasia demonstrate digit and word span lengths below that of neurologically healthy individuals. More specifically, resent research demonstrates that individuals with aphasia with …

Frontal-lobe mediated word retrieval in Parkinson's disease
Parkinsonians have been shown to have difficulty with executive functioning, which is mediated by the frontal lobes of the brain. Tests of verbal fluency have been used to evaluate frontal lobe dysfunction. Letter fluency, however, may require different processes and mechanisms than semantic …

The effect of phonological and semantic cues on word retrieval in adults
<p>Word retrieval difficulties can affect individuals who have had strokes or head trauma (Goodglass & Wingfield, 1997) and to a lesser extent, typically aging adults. This can affect an individual's ability to name pictures accurately and quickly. Cues are used to help individuals with word …

Neural activity reveals effects of aging on inhibitory processes during word retrieval
<p>Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. …

Drawing Conclusions about Aphasia: An Examination of the Relationship between Word Retrieval, Drawing, and Semantics
<p>The hallmark characteristic of aphasia, word retrieval impairment, can significantly affect a person’s ability to communicate their needs and ideas. Treatment for these deficits typically focuses on either restorative or compensatory strategies. In aphasia therapy, clinicians have predominately …

Effects of Semantic Feature Analysis+Multimodal Communication Program for Word Retrieval and Switching Behavior in Primary Progressive Aphasia
… characterized by language and cognitive decline. Word retrieval deficits are the most common PPA symptom, and contribute to impaired verbal expression. Intense semantic interventions show promise for improving word retrieval in people with PPA. Additionally, people with PPA may learn to use …

Semantically-Based Therapeutic Approach Through Aided Language Stimulation in a Child with Autism Spectrum Disorder
… was minimally verbal. Techniques for increasing word retrieval (e.g., the repeated modeling of a small number of target words/symbols) were used in theme-based sessions in conjunction with modeling the use of picture symbols. Overall, the intervention had a small effect on the child's production …

Development and Validation of a New Naming Task: The Southwestern Item Fluency Test (SWIFT)
… across groups, and often ignore speed of word retrieval even though this is a prominent component of word-finding difficulties (WFD). The aim of the current study was to develop and validate a brief, psychometrically sound naming task that is sensitive to WFD. One-hundred items were …

Shifting Semantic Activation via Context: A Study of Aging and Semantic Network Dynamics in Word Production
<p>There is ongoing debate about the locus of word retrieval deficits in aging, and how aging modifies the relationship between contextual processing and word production. Thematic relations among words (e.g., “sun” and “shell” are exemplars of the thematic category “beach”) are of particular …

Neighborhood Density and Word Recognition: Effects of Phoneme Position
… interest in how individuals process single words when they are heard. An examination of the literature reveals an interesting, yet little-explored contradiction between the assumptions underlying the neighborhood activation model (NAM) and contemporary models of word retrieval. In this …

An Investigation of the Impact of Multiple Exposures to New Vocabulary Words have on Students with Language Processing Disorders
… growth in their ability to identify and use the word using a four-point scale. Based on the results of the assessments, they showed that, overall, students made gains in their ability to recall the meaning of words and to use the words appropriately in context. Motivation was measured through …

Incorporating a feature tree geometry into a matcher for a speech recognizer
… in particular, plurals, and the process of word retrieval. The last component is not implemented with the feature tree, but the implications of a tree-based matcher are explored. Initially, a brief overview of the lexical access system is presented for the reader's background. Each component …

The Production and Comprehension Lexicons: What Is Shared and What Is Not
… and comprehension typically propose that word retrieval involves the selection of at least two levels of lexical information, semantic representations and word-forms (phonological and orthographic representations). The results from five experiments tested whether semantic and word-form …

The effects of disclosure on university students' perceptions of a person with aphasia.
… resulting language impairments typically include word-retrieval deficits, which lead to a decreased ability to communicate functionally. This increases the frustration of the person with aphasia (PWA), leading to social isolation, decreased autonomy, and depression. Individuals with aphasia often …

Telepractice in the Communication Treatment of Individuals with Post-stroke Aphasia: Systematic Review
… The treatment areas studies targeted are word retrieval, language skills, communication skills and language and communication skills, with communication skills being the area covered in highest number of studies. The review found that telepractice in the targeted treatment programs is …

Incremental lexical learning in speech production: a computational model and empirical evaluation
… derive from persistent changes in the way that words are activated and selected for production, and some have claimed that the findings are only understandable by positing a competitive mechanism for lexical selection. This dissertation presents and evaluates a simple model of lexical retrieval …
