   How do children learn about the structure of the social world? We tested whether children would extract patterns from an agent's social choices to make inferences about multiple groups’ relative social standing. In Experiment 1, 4‐ to 6‐year‐old children (N = 36; tested in Central New York) saw an agent and three groups (Group‐A,Group‐B, andGroup‐C) and observed the agent choose between pairs of individuals from different groups. Across pairwise selections, a pattern emerged: The agent chose individuals fromGroup‐A > Group‐B > Group‐C. Children tracked the agent's choices to predict thatGroup‐Awas “most‐preferred” and the “leader” and thatGroup‐Cwas “least‐preferred” and the “helper.” In Experiments 2 and 3, we examined children's reasoning about a more complex pattern involving four groups and tested a wider age range. In Experiment 2, 5‐ to 10‐year‐old children (N = 98; tested in Central New York) used the agent's pattern of pairwise choices to infer that the agent likedGroup‐A > Group‐B > Group‐C > Group‐Dand to make predictions about which groups were likely to be “leaders” and “helpers.” In Experiment 3, we found evidence for social specificity in children's reasoning: 5‐ to 10‐year‐old children (N = 96; from 26 US States) made inferences about groups’ relativesocialbut notphysicalpower from the agent's pattern of affiliative choices across the four groups. These findings showcase a mechanism through which children may learn about societal‐level hierarchies through the patterns they observe over time in people's group‐based social choices.

   Children in our sample extracted patterns from an agent's positive social choices between multiple groups to reason about groups’ relative social standing.

   Children used the pattern of an agent's positive social choices to guide their reasoning about which groups were likely to be “leaders” and “helpers” in a fictional town.

   The pattern that emerged in an agent's choices of friends shaped children's thinking about groups’ relativesocialbut notphysicalpower.

   Children tracked social choices to reason about group‐based hierarchies at the individual level (which groups an agent prefers) and societal level (which groups are privileged).

2. The effect of group status on children's hierarchy‐reinforcing beliefs

   Members of advantaged groups are more likely than members of disadvantaged groups to think, feel, and behave in ways that reinforce their group's position within the hierarchy. This study examined how children's status within a group‐based hierarchy shapes their beliefs about the hierarchy and the groups that comprise it in ways that reinforce the hierarchy. To do this, we randomly assigned children (4–8 years;N = 123; 75 female, 48 male; 21 Asian, 9 Black, 21 Latino/a, 1 Middle‐Eastern/North‐African, 14 multiracial, 41 White, 16 not‐specified) to novel groups that differed in social status (advantaged, disadvantaged, neutral third‐party) and assessed their beliefs about the hierarchy. Across five separate assessments, advantaged‐group children were more likely to judge the hierarchy to be fair, generalizable, and wrong to challenge and were more likely to hold biased intergroup attitudes and exclude disadvantaged group members. In addition, with age, children in both the advantaged‐ and disadvantaged‐groups became more likely to see membership in their own group as inherited, while at the same time expecting group‐relevant behaviors to be determined more by the environment. With age, children also judged the hierarchy to be more unfair and expected the hierarchy to generalize across contexts. These findings provide novel insights into how children's position within hierarchies can contribute to the formation of hierarchy‐reinforcing beliefs.

   A total of 123 4–8‐year‐olds were assigned to advantaged, disadvantaged, and third‐party groups within a hierarchy and were assessed on seven hierarchy‐reinforcing beliefs about the hierarchy.

   Advantaged children were more likely to say the hierarchy was fair, generalizable, and wrong to challenge and to hold intergroup biases favoring advantaged group members.

   With age, advantaged‐ and disadvantaged‐group children held more essentialist beliefs about membership in their own group, but not the behaviors associated with their group.

   Results suggest that advantaged group status can shape how children perceive and respond to the hierarchies they are embedded within.

3. The role of vision in the acquisition of words: Vocabulary development in blind toddlers

   https://doi.org/10.1111/desc.13475  

   Campbell, Erin ; Casillas, Robyn ; Bergelson, Elika ( January 2024 , Developmental Science)

   What is vision's role in driving early word production? To answer this, we assessed parent‐report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7–57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N = 6574). We found that on average, blind children showed a roughly half‐year vocabulary delay relative to sighted children, amid considerable variability. However, the content of blind and sighted children's vocabulary was statistically indistinguishable in word length, part of speech, semantic category, concreteness, interactiveness, and perceptual modality. At a finer‐grained level, we also found that words’ perceptual properties intersect with children's perceptual abilities. Our findings suggest that while an absence of visual input may initially make vocabulary development more difficult, the content of the early productive vocabulary is largely resilient to differences in perceptual access.

   Infants and toddlers born blind (with no other diagnoses) show a 7.5 month productive vocabulary delay on average, with wide variability.

   Across the studied age range (7–57 months), vocabulary delays widened with age.

   Blind and sighted children's early vocabularies contain similar distributions of word lengths, parts of speech, semantic categories, and perceptual modalities.

   Blind children (but not sighted children) were more likely to say visual words which could also be experienced through other senses.

4. Teaching little kids big sentences: A randomized controlled trial showing that children with DLD respond to complex syntax intervention embedded within the context of preschool/kindergarten science instruction

   https://doi.org/10.1111/1460-6984.12882

   The language of the science curriculum is complex, even in the early grades. To communicate their scientific observations, children must produce complex syntax, particularly complement clauses (e.g.,I think it will float;We noticed that it vibrates). Complex syntax is often challenging for children with developmental language disorder (DLD), and thus their learning and communication of science may be compromised.

   We asked whether recast therapy delivered in the context of a science curriculum led to gains in complement clause use and scientific content knowledge. To understand the efficacy of recast therapy, we compared changes in science and language knowledge in children who received treatment for complement clauses embedded in a first‐grade science curriculum to two active control conditions (vocabulary + science, phonological awareness + science).

   This 2‐year single‐site three‐arm parallel randomized controlled trial was conducted in Delaware, USA. Children with DLD, not yet in first grade and with low accuracy on complement clauses, were eligible. Thirty‐three 4–7‐year‐old children participated in the summers of 2018 and 2019 (2020 was cancelled due to COVID‐19). We assigned participants to arms using 1:1:1 pseudo‐random allocation (avoiding placing siblings together). The intervention consisted of 39 small‐group sessions of recast therapy, robust vocabulary instruction or phonological awareness intervention during eight science units over 4 weeks, followed by two science units (1 week) taught without language intervention. Pre‐/post‐measures were collected 3 weeks before and after camp by unmasked assessors.

   Primary outcome measures were accuracy on a 20‐item probe of complement clause production and performance on ten 10‐item unit tests (eight science + language, two science only). Complete data were available for 31 children (10 grammar, 21 active control); two others were lost to follow‐up. Both groups made similar gains on science unit tests for science + language content (pre versus post,d= 2.9,p< 0.0001; group,p= 0.24). The grammar group performed significantly better at post‐test than the active control group (d= 2.5,p= 0.049) on complement clause probes and marginally better on science‐only unit tests (d= 2.5,p= 0.051).

   Children with DLD can benefit from language intervention embedded in curricular content and learn both language and science targets taught simultaneously. Tentative findings suggest that treatment for grammar targets may improve academic outcomes.

   We know that recast therapy focused on morphology is effective but very time consuming. Treatment for complex syntax in young children has preliminary efficacy data available. Prior research provides mixed evidence as to children’s ability to learn language targets in conjunction with other information.

   This study provides additional data supporting the efficacy of intensive complex syntax recast therapy for children ages 4–7 with Developmental Language Disorder. It also provides data that children can learn language targets and science curricular content simultaneously.

   As SLPs, we have to talk about something to deliver language therapy; we should consider talking about curricular content. Recast therapy focused on syntactic frames is effective with young children.

5. The impact of sufferers’ wealth status on pain perceptions: Its development and relation to allocation of healthcare resources

   https://doi.org/10.1111/desc.13467

   Wealth‐based disparities in health care wherein the poor receive undertreatment in painful conditions are a prominent issue that requires immediate attention. Research with adults suggests that these disparities are partly rooted in stereotypes associating poor individuals with pain insensitivity. However, whether and how children consider a sufferer's wealth status in their pain perceptions remains unknown. The present work addressed this question by testing 4‐ to 9‐year‐olds from the US and China. In Study 1 (N = 108, 56 girls, 79% White), US participants saw rich and poor White children experiencing identical injuries and indicated who they thought felt more pain. Although 4‐ to 6‐year‐olds responded at chance, children aged seven and above attributed more pain to the poor than to the rich. Study 2 with a new sample of US children (N = 111, 56 girls, 69% White) extended this effect to judgments of White adults’ pain. Pain judgments also informed children's prosocial behaviors, leading them to provide medical resources to the poor. Studies 3 (N = 118, 59 girls, 100% Asian) and 4 (N = 80, 40 girls, 100% Asian) found that, when evaluating White and Asian people's suffering, Chinese children began to attribute more pain to the poor than to the rich earlier than US children. Thus, unlike US adults, US children and Chinese children recognize the poor's pain from early on. These findings add to our knowledge of group‐based beliefs about pain sensitivity and have broad implications on ways to promote equitable health care.

   Four studies examined whether 4‐ to 9‐year‐old children's pain perceptions were influenced by sufferers’ wealth status.

   US children attributed more pain to White individuals of low wealth status than those of high wealth status by age seven.

   Chinese children demonstrated an earlier tendency to attribute more pain to the poor (versus the rich) compared to US children.

   Children's wealth‐based pain judgments underlied their tendency to provide healthcare resources to people of low wealth status.
