“…In studies where phonological cues which corresponded to a semantic coordinate or an associated semantic item (e.g. L(ion) for tiger or W(ater) for bath) significantly increase semantic errors (Howard & Orchard-Lisle, 1984;Soni, et al, 2009;Soni, et al, 2011). Howard and Orchard-Lisle (1984) found that these miscued semantic errors were often not rejected by the speaker.…”

“…Naming accuracy of individuals with central semantic impairments can be improved or disrupted by the provision of cues to an intact system e.g. to the phonological system (Howard & Orchard-Lisle, 1984;Soni et al, 2009;Soni, Lambon Ralph, & Woollams, 2011). For example, naming accuracy is significantly improved by presenting a correct phonological cue alongside the picture to be named (a technique frequently used therapeutically to improve naming in a variety of populations e.g.…”

“…Unrelated phonological cues produce significantly fewer semantic errors than semantically related phonological cues. However, overall accuracy is disrupted to the same extent because unrelated cues produce a high number of omissions (Soni, et al, 2011). It is therefore possible to affect performance of one (impaired) system by providing concurrent or non-concurrent information to a second (intact) system within the central linguistic system.…”

Facilitating and disrupting speech perception in word deafness

Background: Word deafness is a rare condition where pathologically degraded speech perception results in impaired repetition and comprehension but otherwise intact linguistic skills. Although impaired linguistic systems in aphasias resulting from damage to the neural language system (here termed central impairments), have been consistently shown to be amenable to external influences such as linguistic or contextual information (e.g. cueing effects in naming), it is not known whether similar influences can be shown for aphasia arising from damage to a perceptual system (here termed peripheral impairments). Aims: This study aimed to investigate the extent to which pathologically degraded speech perception could be facilitated or disrupted by providing visual as well as auditory information. Methods and Procedures: In three word repetition tasks, the participant with word deafness (AB) repeated words under different conditions: words were repeated in the context of a pictorial or written target, a distractor (semantic, unrelated, rhyme or phonological neighbour) or a blank page (nothing). Accuracy and error types were analysed. Results: AB was impaired at repetition in the blank condition, confirming her degraded speech perception. Repetition was significantly facilitated when accompanied by a picture or written example of the word and significantly impaired by the presence of a written rhyme. Errors in the blank condition were primarily formal whereas errors in the rhyme condition were primarily miscues (saying the distractor word rather than the target). Conclusions: Cross-modal input can both facilitate and further disrupt repetition in word deafness. The cognitive mechanisms behind these findings are discussed. Both 4 top-down influence from the lexical layer on perceptual processes as well as intralexical competition within the lexical layer may play a role.

“…Misleading phonemic cues (e.g. the initial phoneme of a semantically related item, also called a 'miscue'), which presumably strengthen activation of semantic competitors, also lead to significantly poorer picture-naming performance in access deficit patients [39][40][41][42]. These effects have also been found in non-verbal matching tasks: non-verbal sound-to-picture (and sound-to-word) matching [30], selecting an object to complete a common task (e.g.…”

Semantic impairments have been divided into storage deficits, in which the semantic representations themselves are damaged, and access deficits, in which the representations are intact but access to them is impaired. The behavioural phenomena that have been associated with access deficits include sensitivity to cueing, sensitivity to presentation rate, performance inconsistency, negative serial position effects, sensitivity to number and strength of competitors, semantic blocking effects, disordered selection between strong and weak competitors, correlation between semantic deficits and executive function deficits and reduced word frequency effects. Four general accounts have been proposed for different subsets of these phenomena: abnormal refractoriness, too much activation, impaired competitive selection and deficits of semantic control. A combination of abnormal refractoriness and impaired competitive selection can account for most of the behavioural phenomena, but there remain several open questions. In particular, it remains unclear whether access deficits represent a single syndrome, a syndrome with multiple subtypes or a variable collection of phenomena, whether the underlying deficit is domain-general or domain-specific, whether it is owing to disorders of inhibition, activation or selection, and the nature of the connection (if any) between access phenomena in aphasia and in neurologically intact controls. Computational models offer a promising approach to answering these questions.
