“…The Pick-like possibility of a "two stage error" mechanism for neology suggested that a viable alternative would involve some sort of anomic, and that response Pick suggested was a semantic substitute, which was subsequently altered by phonemic error. This set up a prediction for endstage recovery (Eaton, Marshall & Pring 2011). The conduction theory is not a two stage theory, so recovery from that type of neologism would resolve to correct outputs, or perhaps, this could be the endstage speech output monitoring ability as recently suggested and that was not to be confused with anomia.…”

In this paper the authors will discuss the nature of jargonaphasia. Any dictionary definition of the word “jargon” will indicate that once again the medical science of aphasia usurped what was originally a lay term. Some researchers have gone as far as modifying a neologism in adults with that sort of jargon by called recognizable ones “target related” and “non-target related. Even studies of the so-called “semantic pa ra pha sias,” go way beyond what is need to describe any of the three jargons – much less to describe “semantic jargon.” Finally, as we shall see, it is often the case that jargon samples have been elicited from naming tasks, mostly object naming. Nevertheless, it is typical to engage the jargon subjects in tasks that require spontaneous stretches of speech discourse. The complex nature of Jargonaphasia which involve a heterogeneity that will ultimately drive many subcategories of it is discussed. The authors described the 3 jargons of jargonaphasia.

“…The nonwords are usually phonologically related to the target; however, nonwords with no clear phonological overlap with the target have also been reported (Eaton et al . ). Research investigating naming impairments in jargon aphasia has honed in on a deficit either at the phonological level and/or in accessing the phonological level (e.g., Bose and Buchanan , Hillis et al .…”

Background Severe word production difficulties remain one of the most challenging clinical symptoms to treat in individuals with jargon aphasia. Clinically, it is important to determine why some individuals with jargon aphasia improve following therapy when others do not. We report a therapy study with AM, an individual with severe neologistic jargon aphasia, and provide a subsequent comparison with previous cases, with the purpose of informing both our theoretical and clinical understanding of jargon aphasia. Aims To investigate AM's locus of word production deficit and determine the effectiveness of phonological component analysis (PCA) therapy, a phonological cueing therapy, in the re‐learning and generalization of naming responses for words. In addition, AM's performance in therapy, linguistic profile and ability to engage with therapy/cues were compared in a retrospective analysis with the background linguistic and therapy data of two other individuals with jargon aphasia (P9 and FF), who responded differentially to PCA. This was undertake to explore possible prognostic indicators of phonological therapy for jargon aphasia. Methods & Procedures A battery of linguistic and neuropsychological tests was used to identify AM's word production deficit. A single‐subject multiple probe design across behaviours was employed to evaluate the effects of PCA therapy on the re‐learning and generalization of naming responses. In the retrospective analysis of AM, P9 and FF, we compared differences and similarities in performance on various linguistic tasks, the ability to engage in therapy (i.e., ability to generate and use the cues), as well as to retain and maintain cues. Outcomes & Results AM's locus of deficit was identified in the mapping between semantics and phonology. PCA was found to be effective in improving naming in two of the three treated word lists during the treatment phase; however, these gains were not maintained. Generalization to untreated picture names was not observed. Findings from the retrospective analysis illustrated that oral reading skills, the ability to segment phonological information from words and active engagement with provided cues are likely prerequisites for obtaining robust and long‐term gains. Conclusions & Implications We demonstrated that phonological therapy could be beneficial for the remediation of naming abilities at least in the re‐learning phase; however, maintenance and generalization of these gains were limited. This research helps to elucidate the considerations and evaluations necessary for the appropriateness of phonological therapy and candidacy of individuals with jargon aphasia for this treatment approach.

“…Production in Jargon aphasia is fluent but underspecified and contains numerous non-word errors, rendering it hard to comprehend. Prognosis in Jargon aphasia is poor, with reports of declining vocabulary size and mixed therapeutic outcomes (e.g., Panzeri et al, 1987 ; Robson et al, 1998a , b ; Eaton et al, 2011 ; Bose, 2013 ). Perseveration, repeated patterns of phonological distortion, frequently co-occurs with Jargon aphasia and is particularly evident during elicitation tasks such as serial repetition.…”

This study examined patterns of neologistic and perseverative errors during word repetition in fluent Jargon aphasia. The principal hypotheses accounting for Jargon production indicate that poor activation of a target stimulus leads to weakly activated target phoneme segments, which are outcompeted at the phonological encoding level. Voxel-lesion symptom mapping studies of word repetition errors suggest a breakdown in the translation from auditory-phonological analysis to motor activation. Behavioral analyses of repetition data were used to analyse the target relatedness (Phonological Overlap Index: POI) of neologistic errors and patterns of perseveration in 25 individuals with Jargon aphasia. Lesion-symptom analyses explored the relationship between neurological damage and jargon repetition in a group of 38 aphasia participants. Behavioral results showed that neologisms produced by 23 jargon individuals contained greater degrees of target lexico-phonological information than predicted by chance and that neologistic and perseverative production were closely associated. A significant relationship between jargon production and lesions to temporoparietal regions was identified. Region of interest regression analyses suggested that damage to the posterior superior temporal gyrus and superior temporal sulcus in combination was best predictive of a Jargon aphasia profile. Taken together, these results suggest that poor phonological encoding, secondary to impairment in sensory-motor integration, alongside impairments in self-monitoring result in jargon repetition. Insights for clinical management and future directions are discussed.
