Hearing, Language and Communication
No full textAfter a brief description of the neurophysiological basis of development in the first years, the book provides a comprehensive review of the various methods used for the neurological assessment in young infants describing how a combined approach of clinical and instrumental investigations can provide important diagnostic and prognostic information. The first part of the book describes the most used clinical neurological examinations and their applications in infants with neurological abnormalities, followed by a description of the value of neuroimaging and neurophysiological techniques in normal preterm and full term infants in the first two years and the main types of abnormal MR findings of neurophysiological findings (EEG and evoked potentials) in relation to brain lesions.Other sections include chapters describing techniques assessing specific aspects of cognitive, perceptual and sensory abilities.Special attention is given to hearing, language and communication and to development of vision and visual attention both in normal infants and in those with neonatal brain lesions

A longitudinal study of lexical and grammar development in deaf italian children provided with early cochlear implantation
No full textOBJECTIVE:
A growing number of studies on deaf children with cochlear implant (CI) document a significant improvement in receptive and expressive language skills after implantation, even if they show language delay when compared with normal-hearing peers. Data on language acquisition in CI Italian children are still scarce and limited to only certain aspects of language. The purpose of this study is to prospectively describe the trajectories of language development in early CI Italian children, with particular attention to the transition from first words to combinatorial speech and to acquisition of complex grammar in a language with rich morphology, such as Italian.
DESIGN:
Six children, with profound prelingual deafness, provided with CI, between 16 and 24 months of age were prospectively assessed and followed over a mean period of up to 34.8 months postimplant. During follow-up, each child received between four to five individual language evaluations through a combination of indirect procedures (parent reports of early lexical and grammar development) and direct ones (administration of standardized receptive and expressive language tests with Italian norms and collection of spontaneous language samples).
RESULTS:
In relation to chronological age, the acquisition of expressive vocabulary was delayed. However, considering the duration of hearing experience, most CI participants showed an earlier start and faster growth of expressive rather than receptive vocabulary in comparison with typically developing children. This quite atypical result persisted right up until the end of the follow-up. The acquisition of expressive grammar was delayed relative to chronological age, though all but one CI participant achieved the expected grammar level after approximately 3 years of CI use. In addition, the rate of grammar acquisition was not homogeneous during development, showing two different paces: one comparable with normal hearing in the transition from holophrastic to primitive combinatorial speech and a much slower one to attain more advanced levels of morphosyntactic control.
CONCLUSION:
From a rehabilitative viewpoint, our results suggest the importance of implementing rehabilitation in lexical comprehension, even when expressive vocabulary appears to be within normal range. Moreover, assessment of language acquisition in CI Italian children should focus on those grammar aspects that are more vulnerable to early acoustic deprivation (such as free and bound morphology) to ensure enhanced language therapy planning
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
