Yet, the cognitive and neural mechanisms underlying this association remain understudied. This study sought to fill in the gap using both behavioral and neuroimaging methodologies. Eighty\u2010one native Mandarin\u2010speaking children (age = 8.7\u201312.0 years) and their parents were recruited. Family history (FH) of RD and home environmental factors (SES and HLE) were collected, as well as children's diffusion MRI, reading\u2010related cognitive skills (rapid automatized naming [RAN], phonological awareness [PA], and morphological awareness [MA]), and reading outcomes. Participants were divided into the following groups according to their FH of RD and current reading status: children with a FH of RD who showed typical development (FH+TD) or who developed RD (FH+RD), and a typically developing control group without a FH (FH\u2010TD). Chain mediation analyses showed that in FH+TD, the number of children's books (NCB) was linked to the axial diffusivity (AxD) of children's right superior longitudinal fasciculus (rSLF). This neural metric was further linked to children's silent reading comprehension (SRC) via their MA. No such mediation relationship was shown in either FH+RD or FH\u2010TD. These results suggest that reading\u2010related cognitive skills constitute important pathways linking HLE and reading outcomes in at\u2010risk children who developed typical reading skills, while the right\u2010hemispheric white matter fiber tract may serve as one possible neural intermediary. Our findings have educational implications for developing early interventions that focus on enriching HLE to help mitigate the risk of RD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Summary<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>Number of children's books (NCB) is uniquely associated with reading development in children with a family history (FH) of reading difficulties (RD) who nevertheless develop typical reading abilities.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Rapid automatized naming (RAN) serves as a significant cognitive mediator for oral reading fluency (ORF), and morphological awareness (MA) for silent reading comprehension (SRC).
