A comment on Ellwood-Lowe et al. (2020/2021): Presentation and discussion of results should take the lead from the preregistration

Preregistration establishes transparent and verifiable links between hypotheses, statistical tests, and error-control of decisions. In this comment, I critique both the preregistration of, and the presentation of preregistered results from two studies investigating scarcity as a potential cause of the word gap. The primary goal is to illustrate how and why preregistration should guide the way results are framed, and how this might influence conclusions drawn.

409The Word Gap: At What Age Does it Emerge? Results from a Prospective Cohort Study

Background Language is a critical development accomplishment of early childhood, enabling later literacy, education and employment. Previous studies have highlighted socioeconomic inequalities in the amount parents speak to their child, with researchers estimating by age four parents from professional backgrounds spoke 30 million more words to their children, than parents who were on welfare. Methods This study utilises innovative speech recognition technology called Language Environment Analysis (LENA), which counts the number of words children hear and speak over a day. LENA data is collected once every six months from 6 – 48 months of age, across two cohorts of children who are stratified by two levels of maternal education to examine the effects across socioeconomic groups. Results Results from the first three waves of data collection demonstrate that differences between education groups in the number of adult words spoken to the child are not evident until the children are 18 months old. Average change in adult word counts per day by maternal education show there is a difference of 17 words at 6 months, 568 words at 12 months and 3,851 words at 18 months. Conclusions This is the first study to be able to identify the age when socioeconomic differences in the amount of talk emerge. This has significant implications for the timing of interventions aiming to reduce the word gap, suggesting targeting the implementation of programs prior to 18 months. Key messages Socioeconomic differences in the amount parents talk to their children do not emerge until children are 18 months old.

Dismantling Persistent Deficit Narratives About the Language and Literacy of Culturally and Linguistically Minoritized Children and Youth: Counter-Possibilities

Despite decades of efforts, deficit narratives regarding language development and use by children and students from historically marginalized backgrounds remain persistent in the United States. Examining selective literature, we discuss the ideologies that undergird two deficit narratives: the notion that some children have a “word gap” when compared to their White middle-class peers, and students must develop “academic language” to engage in rigorous content learning. The “word gap” concept came from a study wherein a group of young children in low-income families heard fewer words than those in middle-class families. It assumes that language can only be acquired in one way—vocabulary exchange from one parent to one child—and ignores decades of research on diverse pathways for language development. We highlight an alternative perspective that language development builds on children’s experience with cultural practices and the harm on minoritized children by privileging a specific form of vocabulary acquisition. The second deficit narrative concerns “academic language,” a concept championed by scholars aiming to address educational inequity. The construct runs the risk of undervaluing the potential of students from historically marginalized backgrounds to engage in learning using language that is “informal,” nonconventional, or “non-native like.” It also is sometimes used as a rationale to relegate students to special programs isolated from more rigorous academic discourse, thus ironically removing them from opportunities to develop the academic registers they are deemed to be missing. We explore alternative frameworks that shift the focus from linguistic features of academic talk and texts as prerequisites for academic work to the broad range of linguistic resources that students employ for academic purposes in the classroom. Finally, we turn to a positive approach to youths’ language development and use: translanguaging by multilingual learners and their teachers. Translanguaging demonstrates the power of a resource-oriented perspective that values students’ rich communicative repertoires and actively seeks to disrupt language hierarchies. We argue that this approach, however, must be considered in relation to the broader social context to meet its transformative aims. Together, our analysis suggests counter-possibilities to dismantle deficit-oriented narratives and points to promising directions for research and practices to reduce inequity in education.

The education word gap emerges by 18 months: findings from an Australian prospective study

Background The idea of the ‘30 million word gap’ suggests families from more socioeconomically advantaged backgrounds engage in more verbal interactions with their child than disadvantaged families. Initial findings from the Language in Little Ones (LiLO) study up to 12 months showed no word gap between maternal education groups. Methods Families with either high or low maternal education were purposively recruited into a five-year prospective study. We report results from the first three waves of LiLO when children were 6, 12 and 18 months old. Day-long audio recordings, obtained using the Language Environment Analysis software, provided counts of adult words spoken to the child, child vocalizations and conversational turns. Results By the time children were 18 months old all three measures of talk were 0.5 to 0.7 SD higher among families with more education, but with large variation within education groups. Changes in talk from 6 to 18 months highlighted that families from low educated backgrounds were decreasing the amount they spoke to their children (− 4219.54, 95% CI -6054.13, − 2384.95), compared to families from high educated backgrounds who remained relatively stable across this age period (− 369.13, 95% CI − 2344.57, 1606.30). Conclusions The socioeconomic word gap emerges between 12 and 18 months of age. Interventions to enhance maternal communication, child vocalisations and vocabulary development should begin prior to 18 months.

Háblame Bebé: A phone application intervention to support Hispanic children’s early language environments and bilingualism

The early language environments of low-income Hispanic children can be negatively affected when their Spanish-speaking caregivers face racism, assimilation pressure, and/or misinformed advice based on English-only ideologies. This article reports on the design and efficacy of Háblame Bebé, a language-promoting phone application that encourages low-income Hispanic mothers to talk more to their children in their native Spanish with the goals of (1) improving their children’s early language environment, (2) promoting bilingualism, and (3) monitoring developmental milestones. The app was designed and tested across three phases as mandated by the US HRSA Bridging the Word Gap Challenge. In Phase I, we developed a curriculum that promotes high-quality language interactions in Spanish and designed the app components. In Phase II, we tested the app with 20 Hispanic mothers (half high school-educated, half college-educated) in a pretest–posttest design in which we examined their language interactions before and after two months of using the app. Preliminary results indicated that mother–child verbal interactions increased, but not always in their native Spanish, and the difference was not statistically significant. Focus group data revealed that many of the mothers had experienced linguistic racism and that tropes surrounding Spanish-speaking identity in the USA needed to be explicitly addressed within the intervention. In Phase III, a sociolinguistic pride component was added and the app was again tested with 12 additional Hispanic mothers (all high school-educated only). This time, a statistically significant increase in mother–child verbal interactions was found. Mothers also reported feeling prouder to use Spanish with their children. These results suggest that Háblame Bebé may be a viable means to reach low-income Hispanic caregivers who face obstacles in accessing health information and/or home-visiting programs for their children.
