“…Given how frequently semantic cues were used but how infrequently they were effective, clinicians may like to re-consider the value of semantic cueing, especially if aiming for an error minimization approach. There is a growing body of evidence for phonological cueing being effective in reducing error rates (Best et al, 2002;Cheneval et al, 2018) perhaps due to the recruitment of many brain regions (Nardo et al, 2017). However, further research is needed regarding the mechanisms behind the different types of cueing and the longer-term effects of cueing on generalisation to other communication contexts outside the clinic room.…”

Background: Usual care is the term used to describe everyday practice in the management of a client within a profession. The knowledge of the tasks used in therapy and key therapeutic processes used within these treatments, provides critical information about if and how the therapy works. The Very Early Rehabilitation in SpEech Randomised Controlled Trial (VERSE RCT) had three arms with therapists within the intensive Usual Care-Plus arm (UC-Plus) providing daily direct aphasia therapy at their discretion for 20 sessions. Aims: To describe usual care aphasia treatment provided in the Usual Care-Plus arm of VERSE RCT. Methods and Procedures: One in four intensive Usual Care-Plus treatment sessions were video-recorded (N = 187) within the main trial. Twenty-five of these (13%) were transcribed, coded, and analysed for therapeutic inputs to describe usual care aphasia therapy using the Template for Intervention Description and Replication (TIDieR) checklist as an overriding framework. Outcomes and Results: Therapy predominantly took place in an inpatient setting (52%) with an average session duration of 51 minutes (SD 7.8). Across the sessions, 96 different tasks were used and 57% of these focused on verbal expression at the single word level. Visual materials were most frequently used compared to the use of technology during sessions. Therapists (n = 16) did the majority of the talking during sessions and most frequently provided models as cues or problemsolving accuracy feedback. Models (55%), sentence completion (51%), and orthographic cues (44%) were the most successful at eliciting the target response. Conclusions: Considerable variability in task selection was seen in the sample which may be a hallmark of usual care. Therapists may have a preference for single word tasks and appear to produce the majority of verbal utterances during sessions, potentially creating an unequal communication environment. This study provided a comprehensive description from the Usual Care-Plus data of the VERSE RCT and may establish a baseline of therapy type for future research.

“…Also, these effects did not occur in occipital-temporal areas, where the picture is visually processed and recognized. This suggests that the locus of the phonological cueing effect is phonological encoding and not lemma retrieval (Pellet Cheneval et al, 2018) or picture recognition (Meteyard & Bose, 2018).…”

“…There was no interaction with lexical frequency or length in phonemes. On the basis of these findings, Meteyard and Bose conclude that phonological cueing helps the earliest stages of picture recognition rather than lexical selection (Pellet Cheneval et al, 2018) or phonological encoding (Nardo et al, 2017), an insight that they take to be critically important for treatment.…”

Background: Difficulties with word finding occasionally occur in all speakers and commonly in all aphasia types. An understanding of these difficulties and their treatment-induced improvement is of fundamental scientific and clinical importance. Phonological cueing yields immediate and treatment effects in behavioural and neural measures. Disagreement exists about the locus of the cueing effects in aphasia and whether the effects arise from the same neurocognitive mechanisms as phonological effects in picture naming by healthy speakers. Aims: Computer simulations were conducted to expand our understanding of immediate and treatment effects on word finding in behavioural and neural measures and to examine whether a unified account of the phonological effects in health and disease is possible. Methods & Procedure: Picture naming performance of the WEAVER computer model, which accounts for immediate phonological effects in healthy speakers, was assessed in simulations of immediate and treatment effects of phonological cueing in poststroke aphasia. The model assumes (1) a phonological encoding locus of the cueing effects, (2) a cohort mechanism in cue perception, and (3) activation of lexical and sublexical phonological levels by the cues. Outcomes & Results: The model successfully simulated the empirically observed effects in behavioural naming performance and neural measures. Conclusions: The simulations provide a proof of concept for the idea that immediate and treatment effects of phonological cueing in aphasia arise from the same neurocognitive mechanisms as immediate phonological effects in healthy speakers. This expands our understanding of word finding, associated difficulties, and their improvement by therapy.

Background: Even if both phonological and semantic cues can facilitate word retrieval in aphasia, it remains unclear if their respective effectiveness varies according to the underlying anomic profile.Aim: The aim of the present facilitation study is to compare the effect of phonological and semantic cues on picture naming accuracy and speed in different types of anomia.Methods: In the present within-subject design study, 15 aphasic persons following brain damage underwent picture naming paradigms with semantic cues (categorically- or associatively related) and phonological cues (initial phoneme presented auditorily, visually or both).Results: At the group level, semantic cueing was as effective as phonological cueing to significantly speed up picture naming. However, while phonological cues were effective regardless of the anomic profile, semantic cueing effects varied depending on the type of anomia. Participants with mixed anomia showed facilitation after both semantic categorical and associative cues, but individuals with lexical-phonological anomia only after categorical cues. Crucially, semantic cues were ineffective for participants with lexical-semantic anomia. These disparities were confirmed by categorical semantic facilitation decreasing when semantic/omission errors prevailed in the anomic profile, but increasing alongside phonological errors.Conclusion: The effectiveness of phonological vs semantic cues seems related to the underlying anomic profile: phonological cues benefit any type of anomia, but semantic cues only lexical-phonological or mixed anomia.
