A multi-level approach to the analysis of narrative language in aphasia
Andrea Marini, Sara Andreetta, Silvana Del Tin, Sergio Carlomagno, 2011, izvirni znanstveni članek

Opis: Several studies have shown that traditional standardised aphasia tests may not be sensitive enough to adequately assess linguistic deficits and recovery patterns in persons with aphasia. As a result, both functional and structural methods for the ana- lysis of connected language samples from people with aphasia have been devised (see Armstrong, 2000; Prins & Bastiaanse, 2004). The present article focuses on our attempt to provide a comprehensive, multi-level procedure for both structural and functional analysis of narrative discourse produced by speakers with brain damage. Accordingly, we will describe a method for analysis of connected language samples elicited on single picture and cartoon story description tasks. This method has proven sensitive in the assessment of language deficits in many neurogenic populations. A comprehensive description of the language production sys- tem, a thorough discussion of the different approaches to discourse analysis in persons with aphasia, and the procedure for the analysis of narrative discourse are detailed. The characteristics of the eliciting stimuli, the procedures for their administration and the transcription of the language samples are carefully explained. The analysis focuses on four main aspects of linguistic processing: productivity, lexical and grammatical pro- cessing, narrative organisation, and informativeness. To further illustrate the analytic procedure, two case reports and an appendix with the analysis of a narrative sample are provided. We will provide direct evidence of the usefulness of the multi-level procedure for discourse analysis for assessing changes in discourse performance of two persons with fluent aphasia, with different aetiologies, that were not captured by tradi- tional standardised aphasia tests. The method of analysis presented in this paper has strong grounds in linguistic and psychological theories of linguistic structure and functioning. It also has the advantage of being both quantitative and functional as it captures selective aspects of linguistic processing, and can provide relevant information about the person's communicative and informative skills.

Narrative discourse in anomic aphasia
Andrea Marini, Anna Cantagallo, Sara Andreetta, 2012, izvirni znanstveni članek

Opis: Anomic aphasia is a disturbance affecting lexical retrieval. Nonetheless, persons with this disorder may also experience difficulties in the construction of coherent narratives. Whether this symptom is a sign of a macrolinguistic difficulty per se or reflects the lexical disorder is still an open debate. In order to analyze the effect of the lexical impairment on macrolinguistic processing, we compared the narrative skills of a group of ten participants with chronic anomic aphasia with those of ten healthy control individuals matched for age and educational level. The anomic participants produced narratives with lowered speech rate, reduced mean length of utterance, fewer grammatically well-formed sentences, more semantic paraphasias. The macrolinguistic analysis showed that they also produced more errors of cohesion and global coherence and fewer lexical information units. Interestingly, their levels of thematic selection were normal. A bivariate correlational analysis showed a strong correlation between the production of errors of cohesion and production of complete sentences, and between production of errors of global coherence and lexical information units. These correlations showed that aspects related to lexical retrieval may affect macrolinguistic processing during the construction of a narrative. Indeed, it is suggested that lexical deficits lead to two main consequences: First, patients with anomia frequently interrupt the utterances they are producing and this reduces the levels of sentence completeness and the overall degree of cohesion across the utterances; Second, they use strategies to cope with the lexical impairment and produce a quantity of lexical fillers and repetitions that, clustered in utterances, reduce the levels of global coherence.

Patterns of impairment of narrative language in mild traumatic brain injury
Andrea Marini, Marina Zettin, Sara Andreetta, Valentina Galetto, 2013, izvirni znanstveni članek

Opis: Mild traumatic brain injury (mTBI) represents a condition whose cognitive and behavioral sequelae are often underestimated, even when it exerts a profound impact on the patients’ every-day life. The present study aimed to analyze the features of narrative discourse impairment in a group of adults with mTBI. 10 mTBI non-aphasic speakers (GCS > 13) and 13 neurologically intact participants were recruited for the experiment. Their cognitive, linguistic and narrative skills were thoroughly assessed. The group of mTBIs exhibited normal phonological, lexical and grammatical skills. However, their narratives were characterized by the pres- ence of frequent interruptions of ongoing utterances, derailments and extraneous utterances that at times made their discourse vague and ambiguous. They produced more errors of global coherence [F (1; 21)1⁄424.242; p1⁄4.000; h2p1⁄40. 536] and fewer Lexical Information Units [F (1; 21) 1⁄4 7.068; p 1⁄4 .015; h2p 1⁄4 .252]. The errors of global coherence correlated negatively with non- perseverative errors on the WCST (r 1⁄4 1⁄4.755; p < .012). The mac- rolinguistic problems made their narrative samples less informa- tive than those produced by the group of control participants. These disturbances may reflect a deficit at the interface between cognitive and linguistic processing rather than a specific linguistic disturbance. These findings suggest that also persons with mild forms of TBI may experience linguistic disturbances that may hamper the quality of their every-day life.

The effect of lexical deficits on narrative disturbances in fluent aphasia
Andrea Marini, Sara Andreetta, 2015, izvirni znanstveni članek

Opis: Background: The label “fluent aphasia” applies to different aphasic syndromes char- acterised by fluent speech with difficulties in lexical retrieval and/or grammatical processing. Aims: This study aims at investigating microlinguistic and macrolinguistic skills in persons with fluent aphasia. We hypothesised that their lexical and syntactic (i.e., microlinguistic) difficulties would affect also their narrative (i.e., macrolinguistic) skills. Methods & Procedures: Growing evidence shows that traditional tests may not be sensitive enough to capture the patterns of the linguistic impairments observed in these persons. Therefore, we used a narrative task to elicit linguistic samples. Spontaneous speech was elicited through a picture description task. The narrative samples were analysed with a multilevel approach that allows clinicians to quantify their productivity levels as well as their lexical, grammatical, and narrative skills. The spontaneous speech produced by a group of 20 persons with fluent aphasia was compared to that of a group of 20 healthy participants. All participants with aphasia were in the phase of neurological stability. The two groups were matched for age and level of formal education. Outcomes & Results: Results showed that the lexical impairment observed in the group of participants with fluent aphasia hampered the ability to produce well-formed sentences that, in turn, lowered the levels of cohesion of their narrative samples. Furthermore, the reduced levels of lexical informativeness were found correlated also to the production of errors of global coherence. Conclusions: These findings support the hypothesis that in these patients, microlin- guistic difficulties might affect macrolinguistic processing. Furthermore, these results stress the importance of a multilevel approach to assess linguistic skills in patients with fluent aphasia, as it assesses both microlinguistic and macrolinguistic dimensions in parallel. Therefore, it allows linguists, psychologists, and clinicians to observe how the linguistic levels interact during natural language processing.

Thermal lens spectrometry - still a technique on the horizon?
Mladen Franko, 2015

Opis: In 1980’s thermal lens spectrometry (TLS) was still considered as a “spectrometric technique on the horizon” as one can also read from one of the textbooks on spectrochemical analysis of that time. Intensive development of thermal lens instrumentation and methods of chemical analysis and material characterisation has however resulted in substantial progress in this field, which is evident from important instrumental innovations and first commercial instruments (i.e. thermal lens microscopes -TLM) designed for lab-on-a-chip chemistry as well as from novel applications of TLS in various areas, where highly sensitive and rapid chemical analysis of complex samples is needed, including food safety and quality control, environmental analysis and biomedical diagnostics. This presentation is a review of most significant contributions and applications of thermal lens spectrometry, with emphasis on most recent achievements in instrumentation, which culminated into construction of novel optimized TLM instruments, capable of exploiting the tuneability of incoherent light sources and enabled novel applications particularly in micro-fluidics. Based on latest progress relying on bio-analytical assays and micro-fluidic flow injection with TLM detection we have also witnessed firs routine applications of TLS in analytical and diagnostic laboratories, which on wine side actually classifies TLS as a conventional and routine analytical tool, but at the same time opens new horizons for development and applications of this ultrasensitive and rapid spectrometric technique.
