Learning and maintaining new vocabulary in persons with aphasia: Two controlled case studies

Factors influencing treatment-induced language recovery in chronic, post-stroke aphasia

“…Of these 19 participants, 15 individuals demonstrated significant learning effects for the receptive task but not the expressive task. Our findings concur with the results of previous studies, indicating that new word learning is possible in adults with chronic aphasia (Gupta et al, 2006;Kelly & Armstrong, 2009;Tuomiranta et al, 2011;Tuomiranta et al, 2012).…”

“…An emerging body of research has employed the use of novel word learning to investigate verbal learning in adults with aphasia (Gupta et al, 2006;Tuomiranta et al, 2011;Tuomiranta et al, 2012). The use of unfamiliar pictures (i.e., novel semantics) paired with novel word forms in a novel word learning task is suggested to provide a relatively pure measure of individuals' verbal learning capacity.…”

“…A number of studies have explicitly evaluated verbal and non-verbal learning ability in adults with chronic aphasia (Gupta, Martin, Abbs, Schwart, & Lipinski, 2006;Kelly & Armstrong, 2009;Tuomiranta et al, 2011;Tuomiranta, Rautakoski, Rinne, Martin, & Laine, 2012;Vallila-Rohter & Kiran, 2013a, 2013b) and a detailed review of this research is provided in Chapter Five. This research has demonstrated that whilst individuals with aphasia are able to learn new information, both verbal and non-verbal learning mechanisms are impaired in adults with aphasia (Gupta et al, 2006;Kelly & Armstrong, 2009;Vallila-Rohter & Kiran, 2013a).…”

“…A small number of studies have investigated novel word learning in individuals with aphasia (Breitenstein et al, 2004;Freedman & Martin, 2001;Gupta et al, 2006;Kelly & Armstrong, 2009;Tuomiranta et al, 2011;Tuomiranta et al, 2012). These studies indicate that people with aphasia retain, at least in some capacity, the ability to acquire novel verbal information.…”

“…Experimental data indicate that most individuals with aphasia perform better on receptive versus expressive assessments of newly acquired verbal information (Gupta et al, 2006;Kelly & Armstrong, 2009;Tuomiranta et al, 2012) and that there is much individual variability in participants' word learning abilities (Kelly & Armstrong, 2009). However, research conducted to date has utilised small sample sizes (Kelly & Armstrong, 2009;Tuomiranta, Camara, et al, 2014;Tuomiranta et al, 2011;Tuomiranta, Gronroos, et al, 2014;Tuomiranta et al, 2012) and has included participants with aphasia resulting from traumatic brain injury in the sub-acute phase of recovery (Laganaro et al, 2006b). Studies investigating novel word learning in a large sample of participants with chronic, post-stroke aphasia are limited.…”
