ABSTRACT The objective of this paper is to describe the trends in current Brazilian research in numerical cognition, highlighting papers published in the last five years. The studies included in the narrative review have been described considering three thematic groups: numbers; operations and problem-solving; and difficulties or disabilities in learning mathematics. Besides describing the most recent papers in this field, the article includes specific issues, i.e., the active research groups and ways of publishing the research results. The most important conclusions are: there is a diverse growing research field of numerical cognition in Brazil; there is an emphasis on basic research, rather than applied research; most of the research is about children with learning disabilities or difficulties. Despite this growing research in the field, there are no recorded repercussions of the research in Brazil´s educational system, which is a very important challenge for Brazilian researchers.

巴西的数字认知：对一个不断发展的研究领域的叙述性回顾（巴西的数字：对德萨罗洛的研究与发展）

摘要本文的目的是描述巴西目前在数字认知方面的研究趋势，重点介绍最近五年发表的论文。描述性叙述中的研究已考虑了三个主题组：数字；操作和解决问题；以及学习数学的困难或障碍。除了描述该领域的最新论文外，本文还包括一些具体问题，即活跃的研究小组和发表研究成果的方式。最重要的结论是：在巴西，数字认知的研究领域正在不断发展。重点是基础研究，而不是应用研究；大多数研究是关于有学习障碍或学习障碍的儿童的。尽管该领域的研究不断发展，
