Class inclusion versus quantifiers comprehension tasks: an experimental study with school‑aged children Marcella Brunetti1   · Rosalia Di Matteo1 · Tiziana Aureli1 · Maria Concetta Garito1 · Claudia Casadio2 Received: 11 February 2019 / Accepted: 26 September 2020 © Marta Olivetti Belardinelli and Springer-Verlag GmbH Germany, part of Springer Nature 2020

Abstract Literature in developmental psychology pays special attention to the difficulties met by preschool children when confronted with (universal vs. existential) quantified sentences. According to the pivotal Piagetian view, the difficulties exhibited in quantifier comprehension during the preoperational period (age 2–6) derive from the same limitations in logical reasoning that cause bad performance outcomes in class inclusion problems. Nevertheless, as far as we know, a direct comparison between the two tasks has never been produced. In this research we tested the logical hypotheses concerning the failure in quantifier comprehension of preschool children by administering a sentence–picture matching task to two groups of children (5–6 vs. 7–8 years old). Pictures, obtained by partially pairing two entity sets, one of which outnumbers the other, were presented to participants. After each picture, children were asked to answer questions involving quantified versus class inclusion contents. Main findings showed that younger children performed the quantifier task worse than older children and their performance in that task was also worse with respect to the class inclusion task. This difference was not observed with older children who obtained better results than younger children in both tasks. These findings suggest that the specific abilities involved in solving the two problems evolve independently from each other during cognitive development. The results have been discussed in the light of the recent developmental theories. Keywords  Class inclusion · Quantifiers · Cognitive development · Logical reasoning

Introduction Developmental psychology studies, with particular reference to cognitive abilities, pay special attention to the difficulties met by young children when confronted with universal sentences, that is, sentences in which universal quantifiers such as every or all occur (Smith 1980; Roeper and Handling editor: Pia Knoerferle (Humboldt University of Berlin); Reviewers: Francesca Foppolo (University of Milan), Dagmar Bittner (Leibniz-Centre for General Linguistics, Berlin), and two researchers who prefer to remain anonymous. * Marcella Brunetti [email protected] 1
