How do young children develop a concept of equity? Infants prefer dividing resources equally and expect others to make such distributions. Between the ages of 3–8, children begin to exhibit preferences to avoid inequitable outcomes in their distributions, dividing resources unequally if the result of that distribution is a more equitable outcome. Four studies investigated children’s developing preferences for generating equitable distributions, focusing on the mechanisms for this development. Children were presented with two characters with different amount of resources, and then a third character who will distribute more resources to them. Three- to 8-year-olds were asked whether the third character should give an equal number of resources to the recipients, preserving the inequity, or an unequal number to them, creating an equitable outcome. Starting at age 7, children showed a preference for equitable distributions (Study 1, N = 144). Studies 2a (N = 72) and 2b (N = 48) suggest that this development is independent of children’s numerical competence. When asked to take the perspective of the recipient with fewer resources, 3- to 6-year-olds were more likely to make an equitable distribution (Study 3, N = 122). These data suggest that social perspective taking underlies children’s prosocial actions, and supports the hypothesis that their spontaneous capacity to take others’ perspectives develops during the early elementary-school years.

Abstract Young children with limited knowledge of formal mathematics can intuitively perform basic arithmetic‐like operations over nonsymbolic, approximate representations of quantity. However, the algorithmic rules that guide such nonsymbolic operations are not entirely clear. We asked whether nonsymbolic arithmetic operations have a function‐like structure, like symbolic arithmetic. Children (
n = 74 4‐ to ‐8‐year‐olds in Experiment 1;n = 52 7‐ to 8‐year‐olds in Experiment 2) first solved two nonsymbolic arithmetic problems. We then showed children two unequal sets of objects, and asked children which of the two derived solutions should be added to the smaller of the two sets to make them “about the same.” We hypothesized that, if nonsymbolic arithmetic follows similar function rules to symbolic arithmetic, then children should be able to use the solutions of nonsymbolic computations as inputs into another nonsymbolic problem. Contrary to this hypothesis, we found that children were unable to reliably do so, suggesting that these solutions may not operate as independent representations that can be used inputs into other nonsymbolic computations. These results suggest that nonsymbolic and symbolic arithmetic computations are algorithmically distinct, which may limit the extent to which children can leverage nonsymbolic arithmetic intuitions to acquire formal mathematics knowledge. -
Abstract The ability to engage in counterfactual thinking (reason about what else
could have happened) is critical to learning, agency, and social evaluation. However, not much is known about how individual differences in counterfactual reasoning may play a role in children's social evaluations. In the current study, we investigate how prompting children to engage in counterfactual thinking about positive moral actions impacts children's social evaluations. Eighty‐seven 4‐8‐year‐olds were introduced to a character who engaged in a positive moral action (shared a sticker with a friend) and asked about whatelse the character could have done with the sticker (counterfactual simulation). Children were asked to generate either a high number of counterfactuals (five alternative actions) or a low number of counterfactuals (one alternative action). Children were then asked a series of social evaluation questions contrasting that character with one who did not have a choice and had no alternatives (was told to give away the sticker to his friend). Results show that children who generatedselfish counterfactuals were more likely to positively evaluate the character with choice than children who did not generate selfish counterfactuals, suggesting that generating counterfactuals most distant from the chosen action (prosociality) leads children to view prosocial actions more positively. We also found age‐related changes: as children got older, regardless of the type of counterfactuals generated, they were more likely to evaluate the character with choice more positively. These results highlight the importance of counterfactual reasoning in the development of moral evaluations.Research Highlights Older children were more likely to endorse agents who
choose to share over those who do not have a choice.Children who were prompted to generate more counterfactuals were more likely to allocate resources to characters with choice.
Children who generated selfish counterfactuals more positively evaluated agents with choice.
Comparable to theories suggesting children punish willful transgressors more than accidental transgressors, we propose children also consider free will when making positive moral evaluations.

Abstract 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.Research Highlights 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.

Abstract Background 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.Aims 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).
Methods & Procedures 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.
Outcomes & Results 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).Conclusions & Implications 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.
What this paper adds What is already known on the subject 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.
What this study adds 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.
What are the clinical implications of this work? 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.
