“…Our results corroborate the findings of Radanovic et al 33 who found no schooling effects for the Brazilian population with over 8 years of schooling on a comprehensive language test. It also confirms the reference values proposed by Mansur et al 11 for individuals with high education.…”

“…In the present study, even when removing the cards that caused more errors, schooling and, to a lesser degree age, remained significant covariates of performance. Moreover, when comparing our results to those obtained in the study of Mansur et al, 11 only five out of fifteen boards coincided among the ones that yielded more errors (items 8, 13 , 15 , 23 and 48). This inconsistency of performance among individuals needs to be analyzed further in order to decide whether items should be replaced or removed.…”

“…In our population, performance on the KDT has been recently investigated in a sample of Brazilian highly educated healthy young individuals 11 and the total score obtained was lower than that found with English participants, possibly reflecting cultural differences in processing the pictorial stimuli of the KDT. The authors illustrated the use of the test in two patients with dementia (semantic dementia and the behavioral variant of frontotemporal dementia FTDbv) and observed the predicted effects with a more marked impairment for verbs in FTDbv (compared to nouns as assessed by the PPT) and the opposite pattern in SD.…”

Action semantics is a relevant part of cognitive-linguistic assessment and the "Kissing and Dancing Test" (KDT) has been used extensively for this purpose, evidencing clinical distinctions among brain-damaged patients. To enhance its use, reference values are necessary, especially for populations with heterogeneous educational levels and socioeconomic backgrounds.ObjectiveTo analyze the effects of schooling and age on the KDT in cognitively unimpaired individuals.MethodsThe KDT was applied to seventy-four healthy subjects. Sociodemographic factors were investigated through correlational and between-group analyses. Reference values according to age and schooling were provided.ResultsKDT performance correlated significantly with schooling (r=0.757, p<0.01), age (r=–0.496, p<0.01) and socioeconomic status (r=0.418 p<0.01) but these variables were intercorrelated. Correlation with schooling and age remained significant when controlling for age and socioeconomic status (r=0.530, p<0.01), and for schooling (–0.305,<0.01), respectively. When controlling for schooling, correlation between socioeconomic status and KDT was not significant (p=0.164). Between-group analyses revealed no age effects. Significant differences were found in performance according to educational level. Scores below 39/52 and below 47/52 (percentile 25) for individuals with 8 or less years of schooling and for individuals with 9 or more years of schooling, respectively, seem suggestive of an impairment in Action Semantics Processing and shall be further investigated.ConclusionKDT performance was influenced both by age and schooling, indicating the need to consider these demographic features as covariates when analyzing performance on the test and to adjust cut-off scores according to these demographic characteristics in clinical practice.

“…A double dissociation may be postulated between PD patients and those exhibiting selective object-word deficits with relative preservation of action words and action semantics subsequent to posterior atrophy, as observed in Alzheimer's disease [36] and semantic dementia [37,38]. Furthermore, differential activations of frontal/prefrontal regions for verbs, and middle/posterior temporal regions for nouns, have been reported in neuroimaging studies with neurotypical native speakers of English [39,40], German [41], Italian [42], and Japanese [43].…”

In recent years, the disruption of non-motor functions in motor disease has emerged as a promising topic for both basic and translational neuroscience. Impairments of movement and cognition were long regarded as separate phenomena [1]. However, a growing body of evidence indicates that neurodegenerative motor disorders also involve high-order cognitive dysfunctions, ranging from working memory, attention, and executive processing deficits [2][3][4], to impairments of language [4][5][6][7][8][9][10] and action knowledge [11]. Further data comes from studies showing that the same genes (e.g., C9orf72) are involved in diseases once perceived as purely motor or purely cognitive, such as motor neuron disease (MND) and frontotemporal dementia, respectively [12].A cognitive domain which seems to be specifically compromised in motor diseases is action language, that is, processing of linguistic stimuli denoting motor actions, including idioms (e.g., cut a rug) and action verbs Words in moTion: moTor-lAnguAge couPling in PArkinson's diseAse Abstract A growing body of evidence indicates that neurodegenerative motor disorders involved high-order cognitive dysfunctions. Crucially, evidence obtained in multiple behavioral, neuroimaging, and electrophysiological studies points to selective impairments of action language -that is, processing of linguistic stimuli denoting motor actions, including idioms (e.g., cut a rug) and action verbs (e.g., clap). Action-verb deficits (with relative preservation of noun processing) have been repeatedly documented in Parkinson's disease (PD). However, research on relevant biomarkers is still scant, and clinical implications of these findings have not yet been formally discussed. Relevant insights may be obtained through the assessment of motor-language coupling (i.e., the behavioral and neural integration of action-verb processing and ongoing motor actions). We propose that motorlanguage coupling deficits, as indexed by a cortical-subcortical network, may constitute an early neurocognitive marker of PD. Specifically, deficits in this domain at the prodromal stage may be detected through the actionsentence compatibility (ACE) paradigm, which induces a contextual coupling of ongoing motor actions and action-verb processing. Our translational proposal is supported and illustrated by recent studies demonstrating the sensitivity of the ACE technique as well as its potential to assist in differential diagnosis and interventionprogram design.

“…A version of this task was created to assess reading (Rodrigues and Salles, manuscript submitted). In initial phases of research, instruments are available focusing on the assessment of semantic memory, such as the Cambridge semantic memory battery 65 used in patients with Primary Progressive Aphasia in Brazil 66 and the tests of semantic association Pyramids and Palm Trees, and Kissing and Dancing 67 instruments, have been investigated as relevant tools for the diagnosis of neurodegenerative syndromes such as primary progressive aphasia, particularly the semantic variant. 68 , 69 …”

The objective of this paper was to describe the evolution of language assessments in patients with acquired neurological diseases over a period of around 45 years from 1970, when interdisciplinarity in Neuropsychology first began in Brazil, to the present day. The first twenty years of data was based on memories of Speech Pathology University Professors who were in charge of teaching aphasia. We then show the contributions of Linguistics, Cognitive Psychology, as well as Psycholinguistic and Psychometric criteria, to language evaluation. Finally, the current panorama of adaptations and creations of validated and standardized instruments is given, based on a search of the databases Pubmed, Scopus and Lilacs. Our closing remarks highlight the diversity in evaluation approaches and the recent tendency of language evaluations linked to new technologies such as brain imaging and computational analysis.
