Title: Infection detection in faces: Children's development of pathogen avoidance
Abstract This study examined the development of children's avoidance and recognition of sickness using face photos from people with natural, acute, contagious illness. In a U.S. sample of fifty‐seven 4‐ to 5‐year‐olds (46% male, 70% White), fifty‐two 8‐ to 9‐year‐olds (26% male, 62% White), and 51 adults (59% male, 61% White), children and adults avoided and recognized sick faces (ds ranged from 0.38 to 2.26). Both avoidance and recognition improved with age. Interestingly, 4‐ to 5‐year‐olds' avoidance of sick faces positively correlated with their recognition, suggesting stable individual differences in these emerging skills. Together, these findings are consistent with a hypothesized immature but functioning and flexible behavioral immune system emerging early in development. Characterizing children's sickness perception may help design interventions to improve health.  more » « less

  1. 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 HighlightsFour 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.

  2. Abstract With age, people increasingly emphasize intent when judging transgressions. However, people often lack information about intent in everyday settings; further, they may wonder about reasons underlying pro‐social acts. Three studies investigated 4‐to‐6‐year‐olds', 7‐to‐9‐year‐olds', and adults' (data collected 2020–2022 in the northeastern United States, totaln = 669, ~50% female, predominantly White) desire for information about why behaviors occurred. In Study 1, older children and adults exhibited more curiosity about transgressions versus pro‐social behaviors (ds = 0.52–0.63). Younger children showed weaker preferences to learn about transgressions versus pro‐social behaviors than did older participants (d = 0.12). Older children's emphasis on intent, but not expectation violations, drove age‐related differences (Studies 2–3). Older children may target intent‐related judgments specifically toward transgressions, and doing so may underlie curiosity about wrongdoing.

  3. Abstract In response to some resource inequalities, children give priority to moral concerns. Yet, in others, children show ingroup preferences in their evaluations and resource allocations. The present study built upon this knowledge by investigating children's and young adults’ (N = 144; 5–6‐year‐olds,Mage = 5.83,SDage= .97; 9–11‐year‐olds,Mage = 10.74,SDage= .68; and young adults,Mage = 19.92,SDage = 1.10) evaluations and allocation decisions in a science inequality context. Participants viewed vignettes in which male and female groups received unequal amounts of science supplies, then evaluated the acceptability of the resource inequalities, allocated new boxes of science supplies between the groups, and provided justifications for their choices. Results revealed both children and young adults evaluated inequalities of science resources less negatively when girls were disadvantaged than when boys were disadvantaged. Further, 5‐ to 6‐year‐old participants and male participants rectified science resource inequalities to a greater extent when the inequality disadvantaged boys compared to when it disadvantaged girls. Generally, participants who used moral reasoning to justify their responses negatively evaluated and rectified the resource inequalities, whereas participants who used group‐focused reasoning positively evaluated and perpetuated the inequalities, though some age and participant gender findings emerged. Together, these findings reveal subtle gender biases that may contribute to perpetuating gender‐based science inequalities both in childhood and adulthood.

  4. Abstract Adults often respond negatively toward children with incarcerated parents. Yet, the developmental foundations for such negativity remain unclear. Two studies (N = 331 U.S. residents; plurality White; plurality male; data collected between Winter 2019 and Spring 2021) addressed this topic. Study 1 probed 5‐ to 6‐year‐olds' and 7‐ to 8‐year‐olds' inferences about peers with and without incarcerated parents. Children reported less certainty that peers with, versus without, incarcerated parents possess moral beliefs. Study 2 showed that among older children, inferences about parental absence did not fully account for this pattern of results. Across studies, children behaved less generously toward peers with, versus without, incarcerated parents. These studies illuminate how early socio‐moral judgment may contribute to negativity toward children with incarcerated parents.

  5. Abstract Although children exhibit curiosity regarding science, questions remain regarding how children evaluate others' curiosity and whether evaluations differ across domains that prioritize faith (e.g., religion) versus those that value questioning (e.g., science). In Study 1 (n = 115 5‐ to 8‐year‐olds; 49% female; 66% White), children evaluated actors who were curious, ignorant and non‐curious, or knowledgeable about religion or science; curiosity elicited relatively favorable moral evaluations (ds > .40). Study 2 (n = 62 7‐ to 8‐year‐olds; 48% female; 63% White) found that these evaluations generalized to behaviors, as children acted more pro‐socially and less punitively toward curious, versus not curious, individuals ( = .37). These findings (data collected 2020–2022) demonstrate children's positive moral evaluations of curiosity and contribute to debates regarding overlap between scientific and religious cognition.
