Novel metaphors comprehension in a child with High-Functioning Autism Spectrum Disorders. A study on assessment and treatment

Until the first decade of the current millennium, the literature on metaphor comprehension highlighted typical difficulties in children with high-functioning Autism Spectrum Disorder (ASD). More recently, some scholars have devised special programs for enhancing the capability of understanding metaphors in these children. This article presents a case study based on a treatment aiming at enhancing novel metaphor comprehension in a high-functioning child with ASD. M.M., a pseudoacronym for an 8;10 year-old boy, diagnosed with high-functioning ASD, was first assessed with a metaphor comprehension test. This testing (at time TO) highlighted a rigid refusal of metaphors and a marked tendency toward literal interpretation. A baseline treatment (8 sessions of 45-60 min each, twice a week) was implemented, based on a series of recognition, denomination and emotion comprehension activities. M. M.'s metaphor comprehension was assessed a second time (Ti), followed by the experimental treatment (same duration and frequency as the first one), specifically focused on metaphor comprehension. Finally, a third assessment of metaphor comprehension took place (T2), followed by a last assessment 4 months later (follow-up, T3). The comparison between the performances at the metaphor comprehension test across the four assessments, from TO to T3, showed that the baseline treatment produced no effect at all, whereas a significant improvement appeared at T2, just after the experimental treatment, later confirmed at the follow up. Both quantitative and qualitative results showed an evident improvement in the way M.M. handled the semantic issues posed by the metaphors of the test, in line with the strategies he was taught during the treatmen

Beyond the literal meaning of words in children with klinefelter syndrome: two case studies

Literature on children with Klinefelter Syndrome (KS) points to general linguistic difficulties in both comprehension and production among other cognitive functions, and in the majority of cases, these coexist with an intellectual level within the norms. In these conditions, children having language delay generally engage in language therapy and are systematically monitored across ages. In this article, we present the profiles of two children with KS (47, XXY), aged 9.1 (Child S) and 13 (Child D), whose language development was assessed as adequate at age 3, and for this reason, did not receive any language treatment. At the present stage, their IQ, as measured by Wechsler Scales (Child S: 92; Child D: 101), is within the norm, but they both present marked weaknesses in pragmatic skills such as figurative language comprehension. The analysis of these two cases points to the need to go beyond global indexes of verbal abilities, as the same global index may mask a wide diversification of individual profiles. In addition, this study underlines the importance of monitoring the developmental trajectories of children like Child D and Child S, because weaknesses in pragmatic skills that are relevant for both academic achievement and social adaptation could emerge at later stages

Poor written and oral text comprehension in third grade children. A multiple case study

In this multiple case study we analyzed oral text comprehension, reading profiles and underlying cognitive abilities (attention, executive functions, working memory, narrative memory, rapid automatized naming and vocabulary) of 9 children identified as poor written text comprehenders after a school screening on 75 third grade children. Four out of the 9 children were named Language-Minority (L-M) children, since they had immigrant parents. The remaining 5 children were born in Italy from Italian parents. The comparisons of the two subgroups suggested that the lexical route of reading was particularly impaired in the L-M subgroup and that written text comprehension was weakened by restricted vocabulary which, in turn, was not supported by efficient phonological short-term memory. In a second type of data analysis we examined the individual profiles of the 9 children, irrespective of their belonging to the L-M or Italian subgroups, and identified different patterns of associations among reading performance, written text comprehension and oral text comprehension. The findings showed that poor text comprehension always co-occurred with word and/or text reading difficulties which, in turn, were associated to slow naming and weak verbal working memory. Moreover, when children had both written and oral text comprehension difficulties, not only verbal working memory was impaired but also narrative memory, suggesting a weakness in the episodic buffer (Baddeley 2000; 2010). The implications of poor working memory associated to slow naming and/or weak episodic buffer for text comprehension are discusse

Phonological and lexical reading in Italian children with dyslexia

In this study we explore the development of phonological and lexical reading in dyslexic children. We tested a group of 14 Italian children who have been diagnosed with dyslexia and whose reading age is end of grade 1. We compared this group with a group of 70 typically developing children who have been tested for reading at the end of grade 1. For each dyslexic child we also selected a participant who was attending the same grade, was close in age, and showed typical reading development when tested with a narrative passage reading task (Cornoldi, Colpo, & Gruppo MT, 1981) for correctness and reading speed. Children in this group are "same grade controls." We used a reading task consisting of 40 three syllables words. A qualitative and quantitative method of coding children's naming allowed us to distinguish several components of their reading performance: the grapheme and word recognition, the size of orthographic units involved in the aloud orthography-phonology conversion, the reading process used to recognize words. The comparison of the dyslexic group with the reading age and the same grade control groups reveals different trends of delayed reading processes. Considering dyslexic children's chronological age, lexical reading is greatly delayed. Considering dyslexic children's reading age, the type of reading process that is more deeply delayed is phonological reading. The rate of fragmented phonological reading (i.e., a type of syllabized phonological reading) is much higher in dyslexic children compared to the reading age group, suggesting that some factors undermine the possibility of internalizing the orthography-phonology conversion and the blending processes

Training verbal working memory in children with mild intellectual disabilities: effects on problem-solving

This multiple case study explores the effects of a cognitive training program in children with mild to borderline intellectual disability. Experimental training effects were evaluated comparing pre-post-test changes after (a) a baseline phase versus a training phase in the same participant, (b) an experimental training versus either a no intervention phase or a control training in two pairs of children matched for cognitive profile. Key elements of the training program included (1) exercises and card games targeting inhibition, switching, and verbal working memory, (2) guided practice emphasizing concrete strategies to engage in exercises, and (3) a variable amount of adult support. The results show that both verbal working memory analyzed with the listening span test and problem-solving tested with the Raven’s matrices were significantly enhanced after the experimental trainin

La valutazione e l’intervento con D.: disabilità intellettiva o disturbo generalizzato dell’apprendimento?

Assessment and treatment of D.: intellectual or learning disability? The first part of this study is an overview of the controversial evidences supporting the interpretation of IQ in terms of unitary intellective function. Taking into account evidences of cognitive psychology, neuropsychology and biology I argue that impaired learning underlying a deficitary IQ is likely to be generated by: i) deficits in executive functions and working memory; ii) atypical development of some neurobiological structures (i.e., dendrites) supporting the learning process. These same cognitive functions and neurobiological structures, however, can be modified as suggested by both some treatment studies and the environmental enrichment effects in animal models of mental retardation. The second part of the study explores this hypothesis reporting the effects of treating attention, executive functions and verbal working memory in D., a 14-year-old boy with mild intellectual disability
