In order for children to understand and reason about the world in an adult-like fashion, they need to learn that conceptual categories are organized in a hierarchical fashion (e.g., a dog is also an animal). While children learn from their first-hand observation of the world, social knowledge transmission via language can also play an important…

The field of cognitive training (CT) has been researched for over a century. However, there is still a debate regarding its ability to produce cognitive improvement, especially in working memory (WM) indices. This meta-analysis examined whether there is an advantage in training gains by comparing the results of two specific WM training approaches,…

Early childhood is marked by significant developmental changes in the ability to recognize facial expressions. However, since the COVID-19 outbreak, people have been wearing masks more frequently during social interactions which may hamper the recognition of facial expressions. This study examines whether preschoolers recognize the facial…

To date, cross-cultural studies on Theory of Mind (ToM) have predominantly focused on preschoolers. This study focuses on middle childhood, comparing two samples of mainland Chinese (n = 126) and Australian (n = 83) children aged between 5.5 and 12 years. Strange Stories, the most commonly used measure of ToM, was employed. The study aimed to…

Fourteen-month-olds selectively imitated a sub-efficient means (illuminating a lightbox by a head-touch) when this was modeled by linguistic ingroup members in video-demonstrations. A follow-up study with slightly older infants, however, could replicate this effect only in a video-demonstration context. Hence it still remains unclear whether…

There are two lines of discussion regarding the function of the Approximate Number System (ANS). The first line focuses on the extent to which visual cues affect the estimation of numerosity. The second line investigates the extent to which ANS precision is associated with symbolic math performance. The current study combined these two lines of…

In this article, we analyze symbolic and non-symbolic numerical abilities of parents in order to understand whether these are predictors of children's numerical skills, considering basic symbolic, non-symbolic, and formal math skills (i.e., written calculation). A battery of cognitive and math tasks was administered to a sample of 83 children with…

The present study had two aims. First, we set out to evaluate the structure of processing speed in children by comparing five alternative models: two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output response model, and a timing modality model). Second, we then used the…

This experiment tests the age at which left-to-right spatial associations found in infancy shift to culture-specific spatial biases in later childhood, for both numerical and non-numerical information. Children ages 1-5 years (N = 320) were tested within an eye-tracking paradigm which required passive viewing of a video portraying a spatial…

The present study evaluated: (1) the effects of two training programs designed for promoting Theory of Mind (ToM) skills in children aged 7/8; and (2) the relations between second-order recursive thinking (II-order-RT), advanced-ToM (Adv_ToM) and metacognition. Ninety-one 7- to 8-year-old children were assigned to one of three training conditions:…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

Being connected to other people at the level of inner and unobservable mental states is one of the most essential aspects of a meaningful life, including psychological well-being and successful cooperation. The foundation for this kind of connectedness is our theory of mind (ToM), that is the ability to understand our own and others' inner…

Forming social evaluations of others is a core component of social cognition. In this study, the relationship between bilingual experience and social evaluations was investigated in 8-month-old infants. We compared monolingual and bilingual infants' responses to third-party interactions where characters performed prosocial and antisocial actions…

We describe research results and lessons learned from a laboratory/classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

Reading difficulties of children growing up in poverty contexts have not received as much attention as those of children from middle-income families. This paper analyzes the reading-related cognitive profiles of Argentine, Spanish-speaking, low-SES children with reading difficulties (RD), by comparing them with chronological age- (CA) and reading…
