This review aimed to synthesise studies examining the presence of gender stereotypes and biases expressed by young children aged 3–5 years, with a focus on informing early childhood settings. Our review located only 21 separate studies in 16 articles, highlighting a dearth of research in this area. There was substantial heterogeneity in the operationalisation of gender stereotypes and biases. There was evidence that children in early childhood are aware of, and can apply, gender stereotypes. There was also evidence of the malleability of these biases and stereotypes. The social and cultural environment plays a large role in defining the cues by which young children classify on the basis of gender. Research is needed to understand ways to support the establishment of equitable gender attitudes amongst children in early childhood, as this could deliver important benefits to individuals across their lifetime, as well as society more broadly.

这篇综述旨在综合研究年龄在3-5岁的幼儿中性别刻板印象和偏见的研究，重点是为幼儿期提供信息。我们的评论仅对16篇文章中的21项独立研究进行了研究，突显了该领域的研究不足。在性别定型观念和偏见的运作上存在很大的异质性。有证据表明，幼儿期的儿童意识到并可以应用性别定型观念。也有证据表明这些偏见和刻板印象具有延展性。社会和文化环境在确定幼儿根据性别进行分类的线索方面起着重要作用。需要进行研究，以了解支持在幼儿中建立公平的性别态度的方法，
