Aim The differences between parent–child joint attention while reading together from a screen versus from a paper are unknown. The current study aimed to determine if parent–child brains synchronise differently during screen-based versus printed paper-based, in other words, a book reading. Methods The study was carried out in 2022 in Israel. Cohorts were recruited via posted ads. Cognitive and behavioural measures were assessed using standardised tests. In addition, two reading sessions were administered by the parent, one on the screen and another using a book, while electroencephalograph data captured their brain synchronisation. The difference in brain synchronisation between the conditions was correlated with behavioural measures. Results Of the 49 parent–child pairs age 3.94 years ± 0.751; 24 females who participated in language-based tasks for this study, electroencephalograph data from 11 dyads showed a higher brain-to-brain synchronisation during printed-based reading compared to screen-based reading was found and associated with the child's verbal and cognitive abilities. Conclusion Printed-paper reading fosters a higher parent–child neural synchronisation and cognitive engagement compared to screen-based reading.

Objective:Reading difficulties (RD) frequently co-occur with attention-deficit/hyperactivity disorder (ADHD), and children with both RD + ADHD often demonstrate greater challenges in reading and executive functions (EF) than those with RD-only.Methods:This study examined the effect of a 4-week EF-based reading intervention on behavioral and neurobiological correlates of EF among 8–12 y.o. English-speaking children with RD + ADHD (n = 19), RD-only (n = 18), and typically developing children (n = 18). Behavioral and resting-state fMRI data were collected from all participants before and after 4 weeks of the EF-based reading computerized program. Group (RD + ADHD, RD-only, typical readers) x Test (pre- and post-intervention) repeated measures ANOVAs were conducted for reading, EF, and brain functional connectivity (FC) measures.Results:Across groups, reading (fluency, comprehension) and EF (inhibition, speed of processing) behavioral performance improved following the intervention. Exploratory subgroup comparisons revealed that children with RD + ADHD, but not RD-only, showed significant gains in reading comprehension, whereas inhibition improved in both RD groups, but not among typical readers. Furthermore, across groups, FC between the frontoparietal (FP) and cingulo-opercular (CO) networks decreased following the intervention. Exploratory subgroup comparisons revealed that children with RD + ADHD, but not RD-only, showed a significant decrease in FC of FP-CO and FP-dorsal attention network.Conclusions:These results support the differential response to an EF-based reading intervention of children with RD with and without comorbid ADHD at brain and behavioral levels.

The expanded Simple View of Reading model suggests language processing and word reading as contributors to reading comprehension and points at the participation of executive functions as supporting these abilities. Switching and inhibition are both executive functions (EF) contributing to reading, especially in languages with two writing systems—shallow and deep, such as Hebrew. Here, we aimed to determine the specific role of switching/inhibition both cognitively and neurobiologically in the Simple View of Reading model among 49 eight- to 12-year-old Hebrew-speaking children. Children underwent reading and cognitive behavioural testing as well as a five-min resting-state fMRI scan. Functional connectivity of the fronto-parietal network related to switching/inhibition was determined and included in a moderation model. Results suggest that both switching/inhibition abilities and functional connectivity within the fronto-parietal network moderate the relations between word reading and reading comprehension. This strengthens the contribution of switching/inhibition to facilitating reading comprehension and supports the need to include it as part of the expanded SVR model.

The quality of parent-child interaction during shared reading may influence the activation and synchronization of reading-related brain networks. But could differences in brain activity while a child is listening to stories predict parent-child interaction level during reading? For this study, functional MRI including a stories listening task was performed with 22 4-year-old girls and behavioral measurement scores reflecting parent-child interaction as well as maternal depression levels affecting these interactions were collected using video observation data of a shared reading task of these children with their mothers. The study aim was to apply the fMRI stories-listening data to create a diffusion maps algorithm and then attempt to classify the level of parent-child interaction during a shared reading task outside of the scanner. The diffusion maps algorithm successfully clustered children in this manner, with higher parent-child engagement scores related to diffusion patterns in regions of the brain known to support reading. This study demonstrates that applying this diffusion maps algorithm to brain functional connectivity data can predict parent-child interaction during shared book reading. This algorithmic approach is a potential, novel, data-driven means to quantify parent-child interaction in different contexts (e.g., reading, play) and populations.

Narrative comprehension relies on basic sensory processing abilities, such as visual and auditory processing, with recent evidence for utilizing executive functions (EF), which are also engaged during reading. EF was previously related to the “supporter” of engaging the auditory and visual modalities in different cognitive tasks, with evidence of lower efficiency in this process among those with reading difficulties in the absence of a visual stimulus (i.e. while listening to stories). The current study aims to fill out the gap related to the level of reliance on these neural circuits while visual aids (pictures) are involved during story listening in relation to reading skills. Functional MRI data were collected from 44 Hebrew-speaking children aged 8–12 years while listening to stories with vs without visual stimuli (i.e., pictures). Functional connectivity of networks supporting reading was defined in each condition and compared between the conditions against behavioral reading measures. Lower reading skills were related to greater functional connectivity values between EF networks (default mode and memory networks), and between the auditory and memory networks for the stories with vs without the visual stimulation. A greater difference in functional connectivity between the conditions was related to lower reading scores. We conclude that lower reading skills in children may be related to a need for greater scaffolding, i.e., visual stimulation such as pictures describing the narratives when listening to stories, which may guide future intervention approaches.

Background

Smart devices have become an integral part of our lives. However, research has highlighted the potential implications of smartphone presence on task performance, particularly in young children. This study aimed to determine the effect of a smartphone presence on brainwaves associated with cognitive interruption in children.

Methods

EEG data were collected from 5.3 to 8.5-year-old children performing a simple reaction time task with and without the presence of a smartphone. Theta and alpha bands were calculated, and repeated measure analysis of variance was performed to assess the impact of two conditions on alpha and theta bands: 1) with the presence and; 2) without the presence of a smartphone. EEG waveforms were also correlated with standardized cognitive measures evaluating attention abilities using Pearson correlation.

Results

Theta and alpha activity values were higher in the absence vs the presence of a smartphone, with a significant difference between theta bands for the two study conditions. Moreover, the difference between theta bands in the two conditions was significantly correlated with lower scores on an auditory attention test.

Conclusions

The existence of an interactive electronic device during cognitive tasks is associated with alterations in brain activity related to cognitive control.

Impact

The presence of a smartphone during a simple reaction time task in young children was associated with a significant decrease in frontal theta frequency.

A trend of a decreased alpha band in the presence of a smartphone.

The differences in theta and alpha frequencies between conditions were significantly correlated with lower scores in auditory and visual attention and inhibition tests.

Aim Media use in children has exploded in the past several decades, most recently fuelled by portable electronic devices. This study aims to explore differences in functional brain connectivity in children during a story-listening functional MRI (fMRI) task using data collected before (1998) and after (2013) the widespread adoption of media. Methods Cross-sectional data were collected from English-speaking 5- to 7-year-old children at Cincinnati Children's Hospital Medical Center, USA, of a functional MRI narrative comprehension task completed in 1998 (n = 22) or 2013 (n = 25). Imaging data were processed using a graph theory approach, focusing on executive functions, language and visual processing networks supporting reading. Results Group differences suggest more efficient processing in the fronto-parietal network in the pre-media group while listening to stories. A modulation of the visual and fronto-parietal networks for the post-media exposure group was found. Conclusion Further studies are needed to assess effects over time in the more exposed group to discern a causal effect of portable devices on cognitive networks.

Purpose: Rhyming is a phonological skill that typically emerges in the preschool age range. Prosody/rhythm processing involves right-lateralized temporal cortex, yet the neural basis of rhyming ability in young children is unclear. The study objective was to use functional MRI (fMRI) to quantify neural correlates of rhyming abilities in preschool-age children. Method: Healthy pre-kindergarten child-parent dyads were recruited for a study visit including MRI and the Preschool and Primary Inventory of Phonological Awareness (PIPA) rhyme subtest. MRI included a fMRI task where the child listened to a rhymed and unrhymed story without visual stimuli. fMRI data were processed using the CONN functional connectivity (FC) toolbox, with FC computed between 132 regions of interest (ROI) across the brain. Associations between PIPA score and FC during the rhymed vs. unrhymed story were compared accounting for age, sex and maternal education. Results: 45 children completed MRI (age 54+8 months, 37-63; 19M 26F). Median maternal education was college graduate. FC between ROIs in posterior Default Mode (imagery) and right-Fronto-Parietal (executive function) networks was more strongly positively associated with PIPA score during the rhymed compared to the unrhymed story (F(2,39) = 10.95, p-FDR = 0.043), as was FC between ROIs in right-sided language (prosody) and Dorsal Attention networks (F(2,39) = 9.85, p-FDR = 0.044). Conclusions: Preschool-age children with better rhyming abilities had stronger FC between ROIs supporting attention and prosody, and also between ROIs supporting executive function and imagery, suggesting rhyme as a catalyst for attention, visualization and comprehension. These represent novel neural biomarkers of nascent phonological skills.

The Simple View of Reading model suggests that intact language processing and word decoding lead to proficient reading comprehension, with recent studies pointing at executive functions as an important component contributing to reading proficiency. Here, we aimed to determine the underlying mechanism(s) for these changes. Participants include 120 8- to 12-year-old children (n = 55 with dyslexia, n = 65 typical readers) trained on an executive functions–based reading program, including pre/postfunctional MRI and behavioral data collection. Across groups, improved word reading was related to stronger functional connections within executive functions and sensory networks. In children with dyslexia, faster and more accurate word reading was related to stronger functional connections within and between sensory networks. These results suggest greater synchronization of brain systems after the intervention, consistent with the “neural noise” hypothesis in children with dyslexia and support the consideration of including executive functions as part of the Simple View of Reading model.

The traditional models of reading development describe how language processing and word decoding contribute to reading comprehension and how impairments in word decoding, a defining feature of dyslexia, affect reading comprehension outcomes. However, these models do not include word and sentence reading (contextual reading) fluency, both of which engage executive functions, with notably decreased performance in children with dyslexia. In the current study, we compared cortical thickness and sulcal depth (CT/SD) in the cingulo-opercular (CO) executive functions brain network in children with dyslexia and typical readers and examined associations with word vs. contextual reading fluency. Overall, CT was lower in insular regions and higher in parietal and caudal anterior cingulate cortex regions in children with dyslexia. Children with dyslexia showed positive correlations between word reading fluency and CT/SD in insular regions, whereas no significant correlations were observed in typical readers. For sentence reading fluency, negative correlations with CT/SD were found in insular regions in children with dyslexia, while positive correlations with SD were found in insular regions in typical readers. These results demonstrate the differential relations between word and sentence reading fluency and anatomical circuitry supporting executive functions in children with dyslexia vs. typical readers. It also suggests that word and sentence reading fluency, relate to morphology of executive function-related regions in children with dyslexia, whereas in typical readers, only sentence reading fluency relates to morphology of executive function regions. The results also highlight the role of the insula within the CO network in reading fluency. Here we suggest that word and sentence reading fluency are distinct components of reading that should each be included in the Simple View of Reading traditional model.
