In this article, we examine eighth graders' incorrect responses to a specific task on a national standardized assessment of mathematics. The task asked students to write the formula for the perimeter of a given figure as a function of a variable. We focus on incorrect responses to better understand students' difficulties with the algebraic…

A crucial component of mathematics curriculum in primary education is represented by the ability to solve arithmetic word problems. Previous studies investigated predominantly the cognitive factors underlying this skill, neglecting the role of emotional (e.g. math anxiety -- MA) and metacognitive aspects (e.g. perceived difficulty). Some findings…

Children's arithmetic performance is dependent on the arithmetic task format, but little is known about how domain-specific and domain-general abilities contribute to solving diverse arithmetic problems. In this study, 145 Italian typically developing children between the ages of five and six, who have not yet received formal schooling, were…

This article reconsiders Case's theory of central conceptual structures (CCS), examining the relation between working memory and the acquisition of quantitative CCS. The lead hypothesis is that the development of working memory capacity shapes the development of quantitative concepts (whole and rational numbers). Study I, with 779 children from…

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 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 investigated developmental differences in metacognitive monitoring and control in younger (5- to 6-year-old) and older (8- to 10-year-old) children's prospective memory (PM). Metacognitive monitoring was assessed by asking the children to judge their performance before (prediction) and after (postdiction) performing a resource-demanding…

This study aimed to investigate the role of theory of mind (ToM) and both cool and hot executive function (EF) in accounting for prosocial behavior. Typically developing children of 3 to 6 years of age (N = 183) were assessed on a battery of EF and ToM tasks, while parents and teachers completed a questionnaire examining the children's prosocial…

The Test of Emotion Comprehension (TEC) has been used extensively to investigate children's understanding of emotion. The present study aimed at investigating the TEC's factorial structure, its measurement invariance across age and gender, and defining age-referred TEC scores, in a large sample of 1,478 children (755 males, 723 females) aged…

The structure of executive functions in preschoolers is controversial. Miyake and colleagues found that, in adults, inhibition, shifting, and updating are correlated but distinguishable processes; this finding was sometimes replicated with schoolchildren. Based on schoolchildren data, Im-Bolter, Johnson, and Pascual-Leone proposed a four-component…

Research on prospective memory has paid no attention to the way in which the intentions to be remembered are framed. In two studies on time-based prospective memory, participants had to remember multiple delayed intentions framed as time rules (i.e., respond every 7 min, every 10 min) or as a series of corresponding instances (i.e., respond at…

Minority characteristic generic statements such as "ducks lay eggs" are judged to be generally true of the class, despite being true of a minority of cases, such as healthy female ducks of egg-laying age. Five studies explored the factors responsible for the acceptance of minority generic statements about biological kinds. Studies 1 and…

In our everyday life, we often need to anticipate the potential occurrence of events and their consequences. In this context, the way we represent contingencies can determine our ability to adapt to the environment. However, it is not clear how agents encode and organize available knowledge about the future to react to possible states of the…

This study investigated the roles of different executive function (EF) components (inhibition, shifting, and working memory) in 2-step arithmetic word problem solving. A sample of 139 children aged 8 years old and regularly attending the 3rd grade of primary school were tested on 6 EF tasks measuring different EF components, a reading task and a…

Previous findings suggest that religion has a specific impact on attentional processes. Here we show that religion also affects action control. Experiment 1 compared Dutch Calvinists and Dutch atheists, matched for age, sex, intelligence, education, and cultural and socio-economic background, and Experiment 2 compared Italian Catholics with…
