“…She may have been able to benefit from minimal exposure to either mapping operations or to structural information (as provided in the PDSM, for example), to produce passive sentences. For instance, as recently demonstrated in another patient by Inglis (2003), she may have had strong analytical abilities that allowed her to abstract the by-phrase "rule" necessary for correctly producing a passive sentence. That she employed a superficial learned strategy to produce passive sentences is supported by the fact that her sentence comprehension for passive sentences did not improve significantly, even on a test to which she was exposed repeatedly (Picture Comprehension Test).…”

This study investigated a new treatment in which sentence production abilities were trained in a small group of individuals and nonfluent aphasia. It was based upon a mapping therapy approach which holds that sentence production and comprehension impairments are due to difficulties in mapping between the meaning form (thematic roles) and the syntactic form of sentences. We trained production of both canonical and noncanonical reversible sentences. Three patients received treatment and two served as control participants. Patients who received treatment demonstrated acquisition of all trained sentence structures. They also demonstrated across-task generalisation of treated and some untreated sentence structures on two tasks of constrained sentence production, and showed some improvements on a narrative task. One control participant improved on some of these measures and the other did not. There was no noted improvement in sentence comprehension abilities following treatment. Results are discussed with reference to the heterogeneity of underlying impairments in sentence production impairments in nonfluent patients, and the possible mechanisms by which improvement in sentence production might have been achieved in treatment.

“…For example, Cupples and Inglis (1993) demonstrated that a patient who showed a syntactic comprehension deficit on sentence-picture matching showed excellent performance on the same sentence types for actor identification. A more recent study by Inglis (2003) showed that patient performance could be influenced by problem-solving abilities. Consequently, one would like to obtain online measures of processing that are not open to conscious control; however, obtaining reaction time data from brain-damaged patients is also a challenge, given possible motor control problems and the need to collect data from a large number of trials in any condition.…”

The neuropsychology of sentence processing: Where do we stand?

In the early 1980s, sentence comprehension deficits were attributed to a loss of syntactic knowledge in agrammatic Broca's aphasics and to a short-term memory deficit in conduction aphasics. Findings in the remainder of the decade called both of these claims into question and presented general difficulties for the group study approach. Results from case studies support the representational independence of syntactic and semantic information but the interaction of these knowledge sources during processing. Working memory is still considered to provide critical constraints on sentence comprehension, but the capacity involved appears to be largely independent of the phonological storage involved in word list recall. Current computational approaches to sentence comprehension provide the means of accounting for the interaction of multiple sources of information and working memory requirements, but have yet to be tested against neuropsychological findings.

“…Providing sufficient practice items, with feedback, so that the participant learns how to carry out the task as envisaged by the researcher is an important step to counter the generic problem of demand characteristics which remains a potential confound for any offline sentencecomprehension task, even in patients well used to that form of assessment, and without an apparent interpretive deficit (cf. NJ's follow-up plausibility judgements; Inglis, 2003).…”

Background: This article responds to the abstract report of a study by Salis and Edwards (2006). Aims: The aim is to show how that article, and prior articles, have incorrectly interpreted the hypothesis of Cupples and Inglis (1993). A further purpose is to critique other weaknesses of the research paradigm of sentence-picture matching. Main Contribution: It is argued in this paper that it is not appropriate to rule out a potential confound merely on the basis of finding that it does not seem to influence certain patients. Potential confounds should be controlled in the design, for otherwise the result of any study is ambiguous; the effects of the confounded variables cannot be teased apart. Ruling out the confound per se could only come from lack of support for the construct by researchers in the field. In view of the fact that such support exists, the confound remains, and should be addressed by any researcher continuing to make use of sentence-picture matching. Conclusions: The assessment task of sentence-picture matching has been superseded by other tasks which control for the particular confound found by Cupples and Inglis (1993). Testing patients for the confound, even if it turns out not to be operative, is a sign of good experimental control rather than any reflection on the validity of the confound. The task still has perhaps a screening role, but should not be relied on as a valid measure of sentence comprehension. There are inconsistencies in how it is administered across studies, which make comparisons difficult. A range of offline sentence-comprehension tasks is needed in order to be able to triangulate on the nature of a particular patient's comprehension deficit when no single task is ideal.
