The personal epistemology of parents predicts the development of scientific reasoning in children aged 6-10 years.

The influence of the epistemological beliefs of parents on the development of comprehensive scientific reasoning abilities was investigated in a five-wave longitudinal study from kindergarten to elementary school. The 161 German 5-10-year-olds (89 girls, 72 boys) were assessed yearly on their scientific reasoning abilities using comprehensive measures for experimentation and data-interpretation skills, as well as understanding of the nature of science. The children were also tested on their language abilities and intelligence. Their parents completed a sociodemographics questionnaire and answered ten questions about their epistemological beliefs regarding (1) the interpretive nature of science, (2) the tentative nature of knowledge, and (3) the role of scientific framework theories. The personal epistemology of the parents significantly predicted the scientific reasoning development of their children regardless of the parents' education level and the children's general cognitive abilities. However, the effect of the epistemology of parents on their children's scientific reasoning was limited to the intercepts, suggesting that the epistemic understanding of parents affects how scientific reasoning develops in their children, but not the development speed. Although parental epistemology exerts substantial effects on scientific reasoning of their children, it did not affect their reading ability, suggesting an involvement of science-specific mechanisms rather than generalized family-based influences. These findings highlight the importance of family as a variable in the development of scientific reasoning, which is an area lacking in research, and it suggests that early interventions targeted at the epistemic understanding of caregivers can provide useful ways for promoting the reasoning of children. RESEARCH HIGHLIGHTS: A five-year longitudinal study shows significant development of scientific reasoning from kindergarten to elementary school. Caregivers' personal epistemology predicted scientific reasoning development-independent of children's general cognitive abilities and caregivers' level of education. The effect was most-pronounced for caregivers' understanding that social framework theories determine which aspects of science are accepted and how they are conducted. Caregivers' personal epistemology did not predict children's reading abilities, suggesting that the effect of the caregivers' epistemology on children's scientific reasoning is domain-specific.

The complex associations between scientific reasoning and advanced theory of mind.

This 6-wave longitudinal study (2014-2018) of 161 German 5- to 10-year-olds from a midsized city and rural area in southern Germany (89 females, 72 males; predominantly White; mostly middle class) found that scientific-reasoning abilities first develop at 6 years. Abilities were highly stable, with the kindergarten score predicting 25% of end-of-elementary-school variance. Individual but not developmental differences were related to language abilities (0.39), mindreading skills (0.33), and parental education (0.36). In early elementary school, mindreading skills predicted scientific reasoning (0.15), but not vice versa; in late elementary school, bidirectional associations emerged (0.11-0.33). Our findings suggest that mindreading is a precursor for the development of scientific reasoning and that older children use scientific reasoning to revise their advanced theories of mind.

The Development of Advanced Theory of Mind in Middle Childhood: A Longitudinal Study From Age 5 to 10 Years.

This 5-year longitudinal study investigated advanced theory-of-mind (AToM) development in 161 German 5- to 10-year-olds (89 females, 72 males). Core aspects of AToM developed nonlinearly, with children reaching a milestone at the age of 7 years, around when they attained the conceptual insight that mental states can be recursive. In late elementary school, a multicomponent battery was used. Performance on many aspects of AToM was predicted by information-processing skills (intelligence and language at 6 years), but not by the age when children acquired the basic conceptual insight; only some naturalistic, social-interpretative tasks were correlated with children's age at acquisition. This study documents significant developmental progressions in middle-childhood AToM and suggests that different mechanisms may underlie diverse aspects of social cognition.

Scaling of Advanced Theory-of-Mind Tasks.

Advanced theory-of-mind (AToM) development was investigated in three separate studies involving 82, 466, and 402 elementary school children (8-, 9-, and 10-year-olds). Rasch and factor analyses assessed whether common conceptual development underlies higher-order false-belief understanding, social understanding, emotion recognition, and perspective-taking abilities. The results refuted a unidimensional scale and revealed three distinct AToM factors: social reasoning, reasoning about ambiguity, and recognizing transgressions of social norms. Developmental progressions emerged for the two reasoning factors but not for recognizing transgressions of social norms. Both social factors were significantly related to inhibition, whereas language development only predicted performance on social reasoning. These findings suggest that AToM comprises multiple abilities, which are subject to distinct cognitive influences. Importantly, only two AToM factors involve conceptual development.

The development of scientific thinking in elementary school: a comprehensive inventory.

The development of scientific thinking was assessed in 1,581 second, third, and fourth graders (8-, 9-, 10-year-olds) based on a conceptual model that posits developmental progression from naïve to more advanced conceptions. Using a 66-item scale, five components of scientific thinking were addressed, including experimental design, data interpretation, and understanding the nature of science. Unidimensional and multidimensional item response theory analyses supported the instrument's reliability and validity and suggested that the multiple components of scientific thinking form a unitary construct, independent of verbal or reasoning skills. A partial credit model gave evidence for a hierarchical developmental progression. Across each grade transition, advanced conceptions increased while naïve conceptions decreased. Independent effects of intelligence, schooling, and parental education on scientific thinking are discussed.

Does Advanced Theory of Mind Protect Primary-School Children from Loneliness? Longitudinal Relations from 9-10 Years.

Advanced theory of mind (AToM) has been associated with several socioemotional consequences, including loneliness. However, the empirical evidence for this relation is mixed, with some studies finding no significant associations. The present study aimed to replicate and extend previous cross-sectional work. Specifically, we investigated the longitudinal associations between AToM and loneliness in late primary school [from grade 3 (G3) to grade 4 (G4)] by assessing 122 children for AToM (social reasoning) skills, loneliness and self-esteem (aged 9.06 ± .33 years, mean ± SD; 68 girls, 54 boys). Regression analyses showed that G4 loneliness was predicted by G3 self-esteem (ß = .231, p <.05). However, in contrast with earlier findings, neither concurrent nor longitudinal associations emerged between AToM (social reasoning) and loneliness, suggesting that AToM alone affects children's real-world social functioning less than currently assumed.

Some but not all aspects of (advanced) theory of mind predict loneliness.

Children's (advanced) theory of mind (AToM) has been related to numerous real-world social consequences, including regarding their feelings of loneliness. A recent study has shown that AToM does not rely on a single underlying ability, instead involving three distinct factors: social reasoning, reasoning about ambiguity, and recognizing transgressions of social norms. The present study of 229 5- to 8-year-olds investigated whether and how these three aspects of AToM cognition are related to children's feelings of loneliness while controlling for the influence of self-esteem. Our results show that social reasoning is the only AToM factor that is related to children's loneliness, and it is independent from children's self-esteem. Our findings have consequences for the conceptualization of AToM and our understanding of children's feelings of loneliness and their ability to form friendships. Statement of contribution What is already known on this subject Theory-of-mind (ToM) understanding is related to children's ability to form friendships and to their loneliness. Results are mixed concerning the effects of advanced ToM. Recent studies show that advanced ToM is comprised of three separate factors. What the present study adds Social reasoning is the only advanced ToM factor that is related to children's feelings of loneliness. Our results add to our knowledge about diverse real-world consequences of AToM. Our findings have consequences for the conceptualization of AToM.

Preschool children's ability to visually represent relations.

The developmental origins of mapping temporal relations onto space was investigated in N = 122 3- to 5-year-old children and adults. Spontaneous production and comprehension were investigated. Production was investigated in two conditions: an iconic condition (three-dimensional objects depicting the events or objects to be represented) and an abstract condition (plain discs). Consistent with findings by Tversky, Kugelmass and Winter (1991), 5-year-olds performed on an adult-like level. Developmental progress was observed between the ages of 3 and 4 years, with comprehension preceding production. Consistent with DeLoache's findings (2000), 4-year-olds' performance was better in abstract than in iconic conditions, indicating that dual representational demands may have affected task performance in the iconic condition. In sum, abilities to map temporal relations onto spatial relations appear to develop spontaneously, even before children have experience with conventional notational systems.

Scientific thinking in elementary school: Children's social cognition and their epistemological understanding promote experimentation skills.

Do social cognition and epistemological understanding promote elementary school children's experimentation skills? To investigate this question, 402 children (ages 8, 9, and 10) in 2nd, 3rd, and 4th grades were assessed for their experimentation skills, social cognition (advanced theory of mind [AToM]), epistemological understanding (understanding the nature of science), and general information-processing skills (inhibition, intelligence, and language abilities) in a whole-class testing procedure. A multiple indicators multiple causes model revealed a significant influence of social cognition (AToM) on epistemological understanding, and a McNemar test suggested that children's development of AToM is an important precursor for the emergence of an advanced, mature epistemological understanding. Children's epistemological understanding, in turn, predicted their experimentation skills. Importantly, this relation was independent of the common influences of general information processing. Significant relations between experimentation skills and inhibition, and between epistemological understanding, intelligence, and language abilities emerged, suggesting that general information processing contributes to the conceptual development that is involved in scientific thinking. The model of scientific thinking that was tested in this study (social cognition and epistemological understanding promote experimentation skills) fitted the data significantly better than 2 alternative models, which assumed nonspecific, equally strong relations between all constructs under investigation. Our results support the conclusion that social cognition plays a foundational role in the emergence of children's epistemological understanding, which in turn is closely related to the development of experimentation skills. Our findings have significant implications for the teaching of scientific thinking in elementary school and they stress the importance of children's epistemological understanding in scientific-thinking processes.

Testing primary-school children's understanding of the nature of science.

Understanding the nature of science (NOS) is a critical aspect of scientific reasoning, yet few studies have investigated its developmental beginnings and initial structure. One contributing reason is the lack of an adequate instrument. Two studies assessed NOS understanding among third graders using a multiple-select (MS) paper-and-pencil test. Study 1 investigated the validity of the MS test by presenting the items to 68 third graders (9-year-olds) and subsequently interviewing them on their underlying NOS conception of the items. All items were significantly related between formats, indicating that the test was valid. Study 2 applied the same instrument to a larger sample of 243 third graders, and their performance was compared to a multiple-choice (MC) version of the test. Although the MC format inflated the guessing probability, there was a significant relation between the two formats. In summary, the MS format was a valid method revealing third graders' NOS understanding, thereby representing an economical test instrument. A latent class analysis identified three groups of children with expertise in qualitatively different aspects of NOS, suggesting that there is not a single common starting point for the development of NOS understanding; instead, multiple developmental pathways may exist.
