Children's hypothetical reasoning about complex and dynamic systems.

Children's hypothetical reasoning about a complex and dynamic causal system was investigated. Predominantly White, middle-class 5- to 7-year-old children from the Greater Toronto Area learned about novel food chains and were asked to consider the effects of removing one species on the others. In Study 1 (N = 72; 36 females, 36 males; 2018), 7-year-olds answered questions about both direct and indirect effects with a high degree of accuracy, whereas 5-year-olds performed at chance. Six-year-olds showed intermediate performance. Using food chains with clearer constraints, Study 2 (N = 72; 35 females, 37 males; 2020-2021) replicated these findings. These results indicate that the ability to think about hypothetical changes to dynamic causal systems develops between 5 and 7 years. Implications for science education are discussed.

Young children are not driven to explore imaginary worlds.

We address Dubourg and Baumard's claim that imaginary worlds are most appealing early in the lifespan when the exploratory drive is highest. Preschool-age children prefer fictions set in the real world, and fantastical information can be difficult for children to represent in real time. We speculate that a drive to explore imaginary worlds may emerge after children acquire substantial real-world skills and knowledge. An account of age effects on fictional preferences should encompass developmental change.

Learning science concepts through prompts to consider alternative possible worlds.

We investigated whether prompting children to think counterfactually when learning a complex science concept (planetary habitability) would promote their learning and transfer. In Study 1, children (N = 102 6- and 7-year-olds) were either prompted to think counterfactually about Earth (e.g., whether it is closer to or farther from the sun) or prompted to think about examples of different planets (Venus and Neptune) during an illustrated tutorial. A control group did not receive the tutorial. Children in the counterfactual and examples groups showed better comprehension and transfer of the concept than those in the control group. Moreover, children who were prompted to think counterfactually showed some evidence of better transfer to a novel planetary system than those who were prompted to think about different examples. In Study 2, we investigated the nature of the counterfactual benefit observed in Study 1. Children (N = 70 6- and 7-year-olds) received a tutorial featuring a novel (imaginary) planet and were either prompted to think counterfactually about the planet or prompted to think about examples of additional novel planets. Performance was equivalent across conditions and was better than performance in the control condition on all measures. The results suggest that prompts to think about alternative possibilities-both in the form of counterfactuals and in the form of alternative possible worlds-are a promising pedagogical tool for promoting abstract learning of complex science concepts.

Scientific reasoning and counterfactual reasoning in development.

In this chapter, we bridge research on scientific and counterfactual reasoning. We review findings that children struggle with many aspects of scientific experimentation in the absence of formal instruction, but show sophistication in the ability to reason about counterfactual possibilities. We connect these two sets of findings by reviewing relevant theories on the relation between causal, scientific, and counterfactual reasoning before describing a growing body of work that indicates that prompting children to consider counterfactual alternatives can scaffold both the scientific inquiry process (hypothesis-testing and evidence evaluation) and science concept learning. This work suggests that counterfactual thought experiments are a promising pedagogical tool. We end by discussing several open questions for future research.

Designing Narrative-Focused Role-Playing Games for Visualization Literacy in Young Children.

Building on game design and education research, this paper introduces narrative-focused role-playing games as a way to promote visualization literacy in young children. Visualization literacy skills are vital in understanding the world around us and constructing meaningful visualizations, yet, how to better develop these skills at an early age remains largely overlooked and understudied. Only recently has the visualization community started to fill this gap, resulting in preliminary studies and development of educational tools for use in early education. We add to these efforts through the exploration of gamification to support learning, and identify an opportunity to apply role-playing game-based designs by leveraging the presence of narratives in data-related problems involving visualizations. We study the effects of including narrative elements on learning through a technology probe, grounded in a set of design considerations stemming from visualization, game design and education science. We create two versions of a game - one with narrative elements and one without - and evaluate our instances on 33 child participants between 11- to 13-years old using a between-subjects study design. Despite participants requiring double the amount of time to complete their game due to additional narrative elements, the inclusion of such elements were found to improve engagement without sacrificing learning; our results indicate no significant differences in development of graph-reading skills, but significant differences in engagement and overall enjoyment of the game. We report observations and qualitative feedback collected, and note areas for improvement and room for future work.

What is and what never should have been: Children's causal and counterfactual judgments about the same events.

Substantial research with adults has characterized the contents of individuals' counterfactual thoughts. In contrast, little is known about the types of events children invoke in their counterfactual thoughts and how they compare with their causal ascriptions. In the current study, we asked children open-ended counterfactual and causal questions about events in which a character's action enabled a force of nature to cause a minor mishap. Children aged 3.5-8 years (N = 160) tended to invoke characters' actions in their counterfactual judgments to explain how an event could have been prevented (e.g., "She should have closed the window") and tended to invoke forces of nature in their causal judgments (e.g., "The rain got it wet"). Younger children were also significantly more likely than older children to invoke forces of nature in their counterfactuals (e.g., "It shouldn't have rained"). These results indicate that, similar to reasoning patterns found in adults, children tend to focus on controllable enabling conditions when reasoning counterfactually, but the results also point to some developmental differences. The developmental similarities suggest that counterfactual reasoning may serve a similar function from middle childhood through adulthood.

Children's Counterfactual Reasoning About Causally Overdetermined Events.

In two experiments, one hundred and sixty-two 6- to 8-year-olds were asked to reason counterfactually about events with different causal structures. All events involved overdetermined outcomes in which two different causal events led to the same outcome. In Experiment 1, children heard stories with either an ambiguous causal relation between events or causally unrelated events. Children in the causally unrelated version performed better than chance and better than those in the ambiguous condition. In Experiment 2, children heard stories in which antecedent events were causally connected or causally disconnected. Eight-year-olds performed above chance in both conditions, whereas 6-year-olds performed above chance only in the connected condition. This work provides the first evidence that children can reason counterfactually in causally overdetermined contexts by age 8.

Mature counterfactual reasoning in 4- and 5-year-olds.

Counterfactual reasoning is a hallmark of the human imagination. Recently, researchers have argued that children do not display genuine counterfactual reasoning until they can reason about events that are overdetermined and consider the removal of one of multiple causes that lead to the same outcome. This ability has been shown to emerge between 6 and 12 years of age. In 3 experiments, we used an overdetermined physical causation task to investigate preschoolers' ability to reason counterfactually. In Experiment 1a, preschoolers (N = 96) were presented with a "blicket-detector" machine. Children saw both overdetermined (2 causal blocks on a box) and single-cause trials (1 causal and 1 non-causal block) and were asked what would have happened if one of the two blocks had not been placed on the box. Four-year-olds' performance was above chance on both trial types, and 5-year-olds' performance was at ceiling, whereas 3-year-olds did not perform above chance on any trial types. These findings were replicated in Experiment 1b with 4- and 5-year-olds (N = 40) using more complex question wording. In Experiment 2 (N = 40, 4- and 5-year-olds), we introduced a temporal delay between the placement of the first and second block to test the robustness of children's counterfactual reasoning. Even on this more difficult version of the task, performance was significantly above chance. Given a clear and novel causal structure, preschoolers display adult-like counterfactual reasoning.

The Role of Book Features in Young Children's Transfer of Information from Picture Books to Real-World Contexts.

Picture books are an important source of new language, concepts, and lessons for young children. A large body of research has documented the nature of parent-child interactions during shared book reading. A new body of research has begun to investigate the features of picture books that support children's learning and transfer of that information to the real world. In this paper, we discuss how children's symbolic development, analogical reasoning, and reasoning about fantasy may constrain their ability to take away content information from picture books. We then review the nascent body of findings that has focused on the impact of picture book features on children's learning and transfer of words and letters, science concepts, problem solutions, and morals from picture books. In each domain of learning we discuss how children's development may interact with book features to impact their learning. We conclude that children's ability to learn and transfer content from picture books can be disrupted by some book features and research should directly examine the interaction between children's developing abilities and book characteristics on children's learning.

Storybooks aren't just for fun: narrative and non-narrative picture books foster equal amounts of generic language during mother-toddler book sharing.

Parents and children encounter a variety of animals and objects in the early picture books they share, but little is known about how the context in which these entities are presented influences talk about them. The present study investigated how the presence or absence of a visual narrative context influences mothers' tendency to refer to animals as individual characters or as members of a kind when sharing picture books with their toddlers (mean age 21.3 months). Mother-child dyads shared both a narrative and a non-narrative book, each featuring six animals and matched in terms of length and quantity of text. Mothers made more specific (individual-referring) statements about animals in the narrative books, whereas they provided more labels for animals in the non-narrative books. But, of most interest, the frequency and proportion of mothers' use of generic (kind-referring) utterances did not differ across the two different types of books. Further coding of the content of the utterances revealed that mothers provided more story-specific descriptions of states and actions of the animals when sharing narrative books and more physical descriptions of animals when sharing non-narrative books. However, the two books did not differ in terms of their elicitation of natural facts about the animals. Overall, although the two types of books encouraged different types of talk from mothers, they stimulated generic language and talk about natural facts to an equal degree. Implications for learning from picture storybooks and book genre selection in classrooms and home reading are discussed.
