We used human electroencephalogram to study early audiovisual integration of dynamic angry and neutral expressions. An auditory-only condition served as a baseline for the interpretation of integration effects. In the audiovisual conditions, the validity of visual information was manipulated using facial expressions that were either emotionally con...

Primary objective: Does younger age at the time of severe traumatic brain injury (STBI) protect from cognitive symptoms? To answer this question, the authors compared the neuropsychological profile of late school-age children/adolescents and young adult patients at mid- and long-term recovery periods (6 and 12 months post-STBI). Methods and proce...

The human ability to perceive and synchronize to musical beat has communicative importance beyond the purely musical context. Entrainment to the beat hints at more general deductive and predictive mechanisms. Evidence for beat entrainment and its related mechanisms was found in behavioural as well as neuroimaging studies. However, the mechanisms be...

Individuals with Asperger syndrome/High Functioning Autism fail to spontaneously attribute mental states to the self and others, a life-long phenotypic characteristic known as mindblindness. We hypothesized that mindblindness would affect the dynamics of conversational interaction. Using generative models, in particular Gaussian mixture models and...
Article
Does temporal regularity facilitate prediction in audition? To test this, we recorded human event-related potentials to frequent standard tones and infrequent pitch deviant tones, pre-attentively delivered within isochronous and anisochronous (20% onset jitter) rapid sequences. Deviant tones were repeated, either with high or low probability. Stand...

Il Protocollo Montréal per la valutazione delle Abilità Comunicative, adattamento in lingua italiana del Protocole Montréal d'Évaluation de la Communication, è il primo strumento clinico di valutazione delle abilità comunicative in pazienti con danno cerebrale (lesione emisferica destra, trauma cranico) o con disturbi della comunicazione (es., schi...
Article
Purpose: To study the development of sequence memory skills in a group of participants with Spastic Bilateral Cerebral Palsy (CP) and their matched controls (TD). Sequence memory skills are defined as a blend of implicit and explicit competences that are crucial for the acquisition and consolidation of most adaptive skills along the lifespan. Met...
Article
Full-text available
The Mismatch Negativity (MMN) component of the event-related potentials is generated when a detectable spectrotemporal feature of the incoming sound does not match the sensory model set up by preceding repeated stimuli. MMN is enhanced at frontocentral scalp sites for deviant words when compared to acoustically similar deviant pseudowords, suggesti...
Article
Tracing the temporal structure of acoustic events is crucial in order to efficiently adapt to dynamic changes in the environment. In turn, regularity in temporal structure may facilitate tracing of the acoustic signal and its likely spatial source. However, temporal processing in audition extends beyond a domain-general facilitatory function. Tempo...
Article
In the last few years, a growing attention has been paid to the problem of human–human communication, trying to devise artificial systems able to mediate a conversational setting between two or more people. In this paper, we propose an automatic system based on a generative structure able to classify dialog scenarios. The generative model is compos...
Article
Full-text available
We report on the case of an elderly bilingual woman presenting with a diagnosis of primary progressive aphasia. The participant's native language was Friulian (L1), a predominantly oral Romance language, and her second language was Italian (L2), formally learned at primary school in oral and written forms. We investigated her linguistic abilities b...
Article
We present a preliminary investigation on prosody and complex syntax in a boy with Williams syndrome, one mental age matched control and one chronological age matched control. We aimed at verifying the existence of a deficit at the prosody/syntax interface in a language sample elicited by means of a conversational task. Results hint at a specific d...
Article
We investigated sequence-learning skills in 64 children with cerebral palsy (aged 4.01-14.7 years; 49 with bilateral, two with dystonic, and 13 with unilateral cerebral palsy), compared with a matched control group of typically developing children. Participants' motor and handling abilities were classified according to the Gross Motor Function Clas...
Article
The increased interest in social interaction in Williams-Beuren syndrome (WBS) is evident from infancy onwards, together not only with increased empathy, positive interpersonal bias, but also with social disinhibition. Previous studies have described behavioural and emotional problems as being widely represented in WBS. There is limited scope for c...
Article
Infrequent deviant sounds appearing in a repeated, ordered sequence of standard sounds elicit the Mismatch Negativity (MMN) event-related component-indexing regularity violation-if the Inter Stimulus Interval (ISI) is long enough to avoid perceptual grouping and subjects are unaware of the sequential pattern. When pattern structure is explicitly pr...
Article
The neurocognitive profile of Williams-Beuren syndrome (WBS) is characterized by visuospatial deficits, apparently fluent language, motor soft signs, and hypersociability. We investigated the association between neuromotor soft signs and visuospatial, executive-attentive, mnestic and linguistic functions in a group of 26 children and young adults w...
Article
Although typically developing children are attuned early to others’ communicative signals, one of the very first noticeable impairments in children with autism is in attending to voices and speech. Yet it is through conversations with others that children are made aware that apparently edible substances may in reality be contaminated. In two experi...
Article
Nine early non-demented bilingual (L1 - Friulian, L2 - Italian) patients with Parkinson's disease and nine normal controls matched for age, sex and years of education were studied on a spontaneous language production task. All subjects had acquired L1 from birth in a home environment and L2 at the age of six at school formally. Patients with PD evi...
Article
We compared the neurobehavioral profiles of children with Joubert syndrome (JS participants), a rare autosomal recessive condition characterized on magnetic resonance imaging (MRI) by hypoplasia of the cerebellar vermis and midbrain-hindbrain malformations, and children with malformations confined to the cerebellar vermis and one or both hemisphere...
Article
Full-text available
In the last few years, the interest in the analysis of hu-man behavioral schemes has dramatically grown, in partic-ular for the interpretation of the communication modalities called social signals. They represent well defined interac-tion patterns, possibly unconscious, characterizing different conversational situations and behaviors in general. In...
Article
Full-text available
This study aimed at investigating the long-term effects of the combination of severity of injury and time of injury in a 6-year-old bilingual Arabic-Italian child who sustained a severe left traumatic brain injury at the age of 7 months. Standard neurological, cognitive and neuropsychological assessments were administered at 40 days after surgery a...
Article
The phenomenon of lexical Representational Negativity (RN) refers to MMN to words being higher in amplitude than MMN to pseudowords. The nature of such enhancement is currently under investigation. To advance the discussion, in Experiment 1 we replicated the finding of lexical RN with bisyllabic words and pseudowords in fourteen Spanish native spea...
Conference Paper
In the human behavior analysis, the Visual Focus Of Atten- tion (VFOA) of a person is a very important cue. Its detection is di-cult, though, especially in a unconstrained and crowded environment, typical of video surveillance scenarios. In this paper, we estimate the VFOA by deflning the Subjective View Frustum, which approximates the vi- sual fle...

In the last few years, there has been a certain attention to the problem of human-human communication, trying to devise artificial systems able to mediate a conversational setting between two or more people. In this paper, we designed an automatic system based on a generative structure able to classify hard dialog acts. The generative model is comp...
Article
Full-text available
Verbal communication impairments are prominent features of schizophrenia. The grammatical and pragmatic components of expressive and receptive verbal abilities were systematically examined, for the first time, in Italian patients with schizophrenia. Indeed, most of the language literature is composed of studies on English speaking people. Elicited...
Article
This study aims to describe in detail the linguistic skills of a large group of SLI participants. Particular attention is paid to the analysis of age-related effects on their linguistic performance and to whether a linguistic assessment of a narrative task can capture language impairments that might not be adequately pointed out by standardized neu...
Article
Full-text available
Acquired cerebellar lesions in adults and children can lead to the development of a complex behavioural pattern termed 'Cerebellar Cognitive Affective Syndrome' (Schmahmann and Sherman, Brain, 1998; 121: 561-79), which is characterized by reduced cognitive efficiency associated with specific neuropsychological deficits (executive and visuospatial d...
Article
Orofacial praxis is the ability to plan and execute movements or sequences of voluntary movements, meaningful or not, using the muscles of the pharyngo-buccofacial system or the orofacial region. An original test was developed, the Orofacial Praxis Test, consisting of 36 gestures, 24 single and 12 complex, elicited through verbal and imitative requ...
Article
Acquired cerebellar lesions in children and adults may determine deficits of executive functions, visuoperceptual skills, expressive language and modulation of affect; a complex pattern termed 'cerebellar cognitive affective syndrome'. However, the long-term sequelae of malformative cerebellar lesions have yet to be systematically investigated, par...

Conference Paper
Developmental psychology has so far studied pragmatic acquisition with a number of methods, highlighting typical developmental patterns. Quite recently, pragmatic impairments in clinical samples with language disturbances (Developmental Language Disorders, acquired aphasias, early focal lesions, Eisele et al., 1998, Bates, 2004), have gained much a...
Article
Aims: To propose a set of simple linguistic indices for a norm-referenced assessment of narrative speech in children aged 4 to 10 Methods. We analysed narrative production in 213 Italian monolingual children aged 4 to 10 on asset of language indices organised into three domains of inquiry: narrative fluency (total uttered words, narrative time, wor...

To investigate the presence of syntactic impairments in native language in Parkinson's disease. Twelve bilingual patients, with Friulian as their first language (L1) and Italian as their second (L2), with Parkinson's disease and 12 normal controls matched for age, sex, and years of schooling, were studied on three syntactic tasks. Patients with Par...
Article
Two young adult dizygotic twins with high schooling suffered two strokes at the ages of 26 and 30 years. On the first occasion, Case 2 suffered a stroke only a few months after Case 1; on the second occasion, Case 1 suffered a second stroke a few months after Case 2. In Case 1, lesions were mainly localized to the left cerebellar hemisphere in both...
Article
This work discusses the neuropsychological profile of 12 children and adolescents aged 4-15 years, affected with brain tumor (10 astrocytomas 4 of which located in the cerebellum, 4 in the cortex, 1 in the thalamus and 1 in the brainstem; 1 ganglioglioma in the left hippocampus; 1 pituitary craniopharyngioma) assessed before (TEST) and after (RETES...
Article
We present a review of the literature on subcortical aphasia and a follow up study of 5 cases of subcortical aphasia in bilingual patients. Two cases involve damage to thalamic nuclei, while the remaining 3 mainly involve damage to the caudate nucleus and the putamen. Results suggest that the thalamus and basal ganglia of the left hemisfere may be...
Article
This case study aims to investigate whether the treatment of only one language (L2) of a multilingual fluent aphasic(L1 Slovenian, L2 Italian, L3 Friulian, L4 English) results in a parallel improvement of all languages and whether the hypothesized benefits of rehabilitation last four years after the end of treatment. After a first assessment by mea...
