“…Verbal short-term memory in mild aphasia is generally impaired; thus the study replicates previous research on other aphasic groups (see e.g. Meier et al, 1990). But there is also selectivity in the impairment.…”

The effect of mild aphasia (n = 9), as a result of subarachnoid haemorrhage (SAH), was evaluated against one matched (sex, age, and education) control group suffering from SAH of unknown origin without aphasia, and against one matched healthy control group. According to aphasia testing (Reinvang & Engvik, 1980), criteria for a classical diagnosis were not met. Therefore, the patients were characterized as mild aphasics: They generally displayed intact audo-verbal comprehension and repetition abilities, and they demonstrated a fluent, spontaneous speech. However, they showed phonemic and semantic paraphasias, with self-corrections; a few patients displayed alexia and agraphia. Memory performance of these three groups was evaluated by a neuropsychological test battery, designed to tap various components of verbal memory function. From the results it was concluded that: (a) Short-term memory is impaired, as regards the phonological loop and the central executive in working memory, whereas maintenance rehearsal is unaffected, given that the demands on phonological coding is minimized, (b) long-term memory is also generally impaired, whereas long-term learning and forgetting by means of subject-performed tasks proceeds within a normal range. Impairments were hypothesized to reflect less efficient central executive functions of working memory, involving generation of less appropriate semantic codes and phonological representations, (c) mildly aphasic patients are not subjectively aware of their own memory deficits, and (d) aphasia classification by means of standard procedures do not sufficiently characterize the nature of a mildy aphasic patient's memory problems.

“…Other independent evidence (Meier et al, 1990) agrees with this conclusion. Meier et al ( 1990) used a verbalizable token test (same-different decisions on one dimension of coloured squares and circles that vaned in size), both with and without distractors (verbal and non-verbal).…”

“…16 Further studies controlling for more possibly influential factors will be needed to clarify the crucial characteristics of patients who take advantage of tactile feedback. It may be relevant that the Token Test has been considered as a test of abstract attitude rather than of language comprehension in a narrow sense.…”

“…General agreement exists in the literature that individuals with aphasia (IWA) present with impaired memory systems in conjunction with deficits in language processes (e.g., Burgio & Basso, 1997; Erickson, Goldinger, & LaPointe, 1996; LaPointe & Erickson, 1991; Martin & Saffran, 1997; Meier, Cohen, & Koemeda-Lutz, 1990; Ronnberg et al, 1996; Warrington & Shallice, 1969). Further, there is also general agreement that adults with aphasia present with a WM deficit that contributes to their language processing impairments (e.g., Caspari, Parkinson, LaPointe, & Katz, 1998, Friedmann & Gvion, 2003; Laures-Gore, Marshall, & Verner, 2010; Martin, 2008; Ronnberg et al, 1996; Sung, McNeil, Pratt, Dickey, Hula, Szuminsky, & Doyle, 2009; Ween, Verfaellie, & Alexander, 1996; Wright, Downey, Gravier, Love, & Shapiro, 2007; Wright & Shisler, 2005; Yasuda & Nakamura, 2000).…”

Background General agreement exists in the literature that individuals with aphasia can exhibit a working memory deficit that contributes to their language processing impairments. Though conceptualized within different working memory frameworks, researchers have suggested that individuals with aphasia have limited working memory capacity, impaired attention-control processes as well as impaired inhibitory mechanisms. However, across studies investigating working memory ability in individuals with aphasia, different measures have been used to quantify their working memory ability and identify the relationship between working memory and language performance. Aims The primary objectives of this article are to (1) review current working memory theoretical frameworks, (2) review tasks used to measure working memory, and (3) discuss findings from studies that have investigated working memory as they relate to language processing in aphasia. Main Contribution Though findings have been consistent across studies investigating working memory ability in individuals with aphasia, discussion of how working memory is conceptualized and defined is often missing, as is discussion of results within a theoretical framework. This is critical, as working memory is conceptualized differently across the different theoretical frameworks. They differ in explaining what limits capacity and the source of individual differences as well as how information is encoded, maintained, and retrieved. When test methods are considered within a theoretical framework, specific hypotheses can be tested and stronger conclusions that are less susceptible to different interpretations can be made. Conclusions Working memory ability has been investigated in numerous studies with individuals with aphasia. To better understand the underlying cognitive constructs that contribute to the language deficits exhibited by individuals with aphasia, future investigations should operationally define the cognitive constructs of interest and discuss findings within theoretical frameworks.
