How did the CATALISE criteria adapt the intelligence (IQ) requirements for diagnosing DLD compared to traditional SLI criteria?

They adapted the criteria so as not to exclude children with a low IQ, provided they did not have an intellectual disability diagnosis.

What is the primary definition of the DLD diagnostic criterion according to the CATALISE consensus?

A persistent language delay, not resolved at age 5, that affects everyday communication and/or learning, which cannot be explained by a medical condition like brain injury or hearing loss.

How did the researchers in this study handle the diagnostic criteria to avoid controversy regarding comorbidity?

They used the label DLD but applied SLI criteria, meaning all selected children had a normal IQ and no other diagnoses except language difficulties.

How do the language learning profiles of bilingual children with DLD compare to monolingual peers with DLD?

Bilingual children learn both languages slower than age-matched monolinguals, but overall, they do not exhibit worse linguistic profiles than monolingual children with DLD.

How does the orthographic depth of a language affect reading acquisition?

A deeper orthography (lower correspondence between graphemes and phonemes) increases the time and complexity required to learn to read.

What role does rapid automatized naming (RAN) play in orthographically transparent languages compared to deep ones?

Rapid automatized naming has a greater impact on literacy development in orthographically transparent languages, sometimes being the unique predictor of reading in children with DLD.

What is a potential disadvantage of the inclusive education model in Spain for children with DLD?

The lack of visibility makes it easy for DLD to go unnoticed, making early detection and applying learning aids difficult in inclusive contexts.

What were the two primary objectives of this longitudinal study?

First, to describe the academic results of bilingual Catalan-Spanish children with DLD compared to peers; second, to identify the best pre-school processing predictors of these results.

How many children completed the follow-up in this longitudinal study, and what were the starting and ending grades?

Twenty-eight children completed the study (14 with DLD, 14 controls), starting in the 1st year of primary school (age 6) and ending in the last year of primary school (age 12).

On what variables was each child with DLD paired with a control child?

They were paired with a peer from the same classroom, of the same age, sharing the same gender, socioeconomic status (SES), and family language.

At what age do children in the studied Balearic context typically start school?

Schooling begins at 3 years of age, and children had already completed two years of kindergarten prior to the study's identification phase.

Which assessments were used to evaluate oral language skills at the 12-year follow-up?

Language comprehension was measured using the CEG, and language production was evaluated via the NEPSY sentence repetition subtest.

What linguistic characteristics do Spanish and Catalan share that facilitate code-switching in this dual-language context?

They share 76% of cognates, both have highly orthographically transparent structures, and they feature highly similar morphosyntactic structures.

How was semantic verbal fluency measured in the study's cognitive processing battery?

It was measured by counting the total number of distinct words the child could produce in 1 minute for two semantic categories (animals and food/drinks).

How did the rate of grade retention differ between the DLD and control groups?

Grade retention was significantly higher in the DLD group, with eight children repeating a grade compared to only one child in the control group.

What percentage of children in the DLD group had curriculum adaptations, and what was its association with grade retention?

Only 29% (four children) received curriculum adaptations, and there was a significant association as all of these children also repeated a grade.

What did the Group x Cycle interaction reveal about the academic marks of children with DLD?

The DLD group showed a significant decrease in average academic marks between the second and third cycles of primary school, whereas the control group did not.

In which primary school subjects did children with DLD achieve significantly lower marks than controls in the 3rd cycle?

They achieved significantly lower marks in science/social knowledge, art, Spanish, Catalan, and English, but did not significantly differ in math or physical education.

What was the unique significant predictor of the average academic mark in the control group?

Phonological awareness was the sole predictor, accounting for 53.6% of the variance.

Which three pre-school cognitive measures predicted academic outcomes when combining both groups, and how much variance did they explain?

Rapid naming, phonological awareness, and comprehension of instructions, which collectively explained 75.8% of the variance.

Why might phonological awareness be less critical for predicting academic outcomes in Spanish-Catalan DLD children than in English ones?

Because Spanish and Catalan are orthographically transparent languages, meaning decoding is easier, which reduces the predicting impact of phonological awareness.

Why does rapid naming play such a crucial role in predicting academic outcomes for Spanish-Catalan children with DLD?

Rapid naming speeds up arbitrary orthographic-phonological associations, which are essential for reading fluency and comprehension in transparent orthographies.

What does the study suggest about the effectiveness of current Spanish academic adaptations for children with DLD?

Neither curriculum adaptations nor grade retention worked adequately, as shown by the progressive worsening of DLD academic results at the end of primary education.

What are the primary limitations of the study's longitudinal design and sample size?

The relatively small participant sample size (N=28), due to strict diagnostic inclusion criteria and experimental mortality (dropouts) during the follow-up.

Which standardized tests were used in the identification phase to measure language profiles and non-verbal IQ?

The PLON-R (Navarra Oral Language Test-Revised) was used for language profiles, and the WPPSI was used to measure non-verbal IQ.

Did visual attention correlate with the academic outcomes of children with DLD in this study?

No, visual attention only correlated with academic outcomes in typically developing (control) children, not in the DLD group.

What recommendations do the authors propose to reduce academic failure in children with DLD?

They recommend targeted stimulation of rapid naming and language, as well as high-quality classroom adaptations that support decoding and academic learning.

How did the NEPSY rapid naming task used in this study differ from conventional rapid automatized naming (RAN) tasks?

It required children to name three dimensions (size, color, and shape) simultaneously instead of one, increasing demands on attention and working memory.

Why was the mean age of the DLD group significantly higher than the control group at the end of primary school?

Because the children in the DLD group experienced grade retention significantly more often than their control peers.

What limitation did the authors note regarding their assessment of phonological awareness?

They used a syllable-level task rather than a phoneme-level task, which may have been less sensitive in detecting differences between the groups.
