Language-Specific Effects in Response to Spelling Intervention in Italian and in English as an Additional Language
No full textAccording to a language-integrated view of spelling development, learning to spell involves the same language-learning skills across alphabetic systems. A prediction based on this view is that the same spelling training should be equally effective for learning to spell in a shallow (Italian, native language) or an opaque (English, additional language) orthography. We tested this prediction by teaching 6- to 9-year-old Italian children to use multiletter spelling units to spell words in Italian and English. The children were trained on the spelling of Italian words containing orthographic difficulties that required switching from phoneme–grapheme spelling correspondences to larger grain size (multiletter) spelling units. In a stepped-wedge cluster randomized trial, 108 Italian children (ages 6–9 years) were assigned to the experimental spelling training or a waiting list condition. Their ability to spell the trained (Italian and English) word lists and to generalize the acquired knowledge to new (untrained) words was assessed. Similar learning effects were found in the two languages for the trained word lists. However, generalization of the acquired spelling knowledge to new words occurred only in English. The influence of language-specific factors on learning to spell could account for these findings
The influence of first language spelling and response inhibition skills on English-as-an-additional-language spelling
No full textEnglish spelling is widely investigated, but little is known about spelling in English as an additional language (EAL), especially in the context of text production. This study examined the contribution of language-specific Italian and EAL spelling knowledge, and inhibition skills to EAL spelling in Italian adolescents’ essays. Fifty students, attending two language-focused high schools in Italy, completed standardized spelling tests in Italian and English, a Flanker task to assess inhibition skills, and two, persuasive texts in English. Texts were scored for spelling errors, fluency (words/minute), lexical diversity (type token ratio, TTR), and productivity (total words). Spelling errors in EAL writing were 3%. An exploratory factor analysis identified two factors accounting for EAL spelling in writing: a general EAL spelling/writing (including spelling ability, writing fluency, TTR and total words) factor, and a cognitive factor, corresponding to response inhibition skills. Italian spelling skills did not predict EAL-in-text spelling. The only significant predictors of spelling in EAL writing were EAL spelling/writing and inhibition skills. Inhibition skills contributed to explain morphological and code-switch errors, but not phonological and orthographic errors in English texts. These findings align with the contrastive typological framework and phonological and orthographic proximity hypothesis of language transfer
Time-Course of Grammatical Processing in Deaf Readers: An Eye-Movement Study
No full textTwenty participants who were deaf and 20 chronological age-matched participants with typical hearing (TH) (mean age: 12 years) were asked to judge the correctness of written sentences with or without a grammatically incongruent word while their eye movements were registered. TH participants outperformed deaf participants in grammaticality judgment accuracy. For both groups, First Pass and Total Fixation Times of target words in correct trials were significantly longer in the incongruent condition than in the congruent one. However, whereas TH students showed longer First Pass in the target area than deaf students across congruity conditions, deaf students made more fixations than their TH controls. Syntactic skills, vocabulary, and word reading speeds (measured with additional tests) were significantly lower in deaf students but only syntactic skills were systematically associated to the time-course of congruity processing. These results suggest that syntactic skills could have a cascading effect in sentence processing for deaf readers
Oral sentence generation training to improve fifth and 10th graders’ writing
Full text linkText generation—the mental translation of ideas into language at word, sentence, and discourse levels—involves oral language abilities. However, oral language skills are rarely a target of writing interventions. We ran an intervention to improve fifth and 10th graders’ written production through the development of oral sentence generation (grammatical and syntactic) skills. One hundred and fifteen students—68 fifth graders (four classrooms) and 47 tenth graders (four classrooms)—participated in a stepped-wedge cluster-randomized controlled trial. Two fifth-grade classrooms (n = 35) and two 10th-grade classrooms (n = 20) received nine 90-min sessions (3 weeks, three sessions a week) of oral language intervention immediately after the pretest (experimental groups); the two other fifth- (n = 33) and 10th-grade classrooms (n = 27) received business-as-usual writing instruction and received a delayed oral language intervention after the posttest (waiting list group). The intervention consisted of team-based games to improve oral sentence generation and sentence reformulation skills. We assessed written sentence generation, written sentence reformulation, written text quality (macrostructure and language), and text writing fluency before (pretest) and after (posttest) the intervention and 5 weeks after the intervention (follow-up). The results showed that training on oral sentence generation skills can lead to significant gains in both sentence generation and sentence reformulation skills and text macrostructural quality. Improvement at the sentence level was, however, significant only for the younger writers (fifth graders)
Cumulative semantic cost without successful naming
Full text linkAccessing semantic information has negative consequences for successive recovering attempts of similar information. For instance, in the course of picture-naming tasks, the time required to name an object is determined by the total number of items from the same category that have already been named; naming latencies increase proportionally to the total number of semantically related words named previously. This phenomenon is called cumulative semantic cost (or interference). Two picture-naming experiments with children (4–11 years old, 229 participants) investigate whether having successfully named the previous within-category items is a necessary condition for the cumulative semantic cost to appear. We anticipated that younger children would have a larger rate of nonresponses compared with older children, reflecting the fact that younger children have not yet consolidated many lexical representations. Our results confirmed this prediction. Critically, we also observed that cumulative semantic cost was independent of having successfully retrieved previous within-category lexical items. Furthermore, picture trials for which the previous within-category item elicited a nonresponse showed the same amount of cost as those picture trials for which the previous within-category item elicited a correct naming event. Our findings indicate that it is the attempt to retrieve a lexical unit, and not the successful retrieval of a specific lexical unit, that causes semantic cost in picture naming. This cost can be explained by a mechanism of weakening the semantic-to-lexical mappings of semantic coordinate words. The findings are also discussed in the context of retrieval-induced forgetting effects in memory recall research
The cognitive effects of computational thinking: A systematic review and meta-analytic study
Full text linkIn this paper, we review and meta-analyze the findings of experimental studies published between 2006 and 2022 that examined the effects of coding and programming interventions on children's core and higher order executive functions (response inhibition, working memory, cognitive flexibility, planning and problem solving). The systematic review and meta-analysis aimed to address three research questions: 1) Which executive functions are most impacted by the teaching of CT? 2) Which instructional modality (educational robotics/virtual coding/unplugged coding) is most effective in enhancing executive function skills in learners aged 4–16 years? and 3) Does the cognitive effectiveness of coding vary with children's age? A total of 19 studies with 1523 participants met the selection criteria for the systematic review. The meta-analysis included 11 of those studies. The results reveal beneficial effects of structured virtual and tangible coding (educational robotics) activities for preschoolers and first graders, and significant effects of more unstructured virtual coding activities (e.g., Scratch-based) for older students. A multivariate fixed-effects model meta-analysis shows that the teaching of coding significantly improves problem-solving with the highest effect (dppc2 = 0.89), but also planning (dppc2 = 0.36), and inhibition and working memory with lower effects (dppc2 = 0.17, dppc2 = 0.20)
How primary classes visually represent while temporal relations: A preliminary evaluation study
No full textWe are working on a temporal reasoning web tool for novice readers. The acquisition of temporal relations and reasoning with them depends on age and experience, as well as linguistic factors. We conducted a preliminary evaluation with 6-8 olds in order to assess whether and how they would visually represent "while" temporal relations of a story. In this paper, we present and discuss our experimental evaluation, which paves the way for the visual representation of such relations in our e-tool.

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
