We describe 62 gesture forms in the preverbal repertoire. These were categorized into deictic, iconic, non-referential and conventional gesture types, similar to co-speech gesture types. We also find that the type-function relation of preverbal gestures map similarly to type-meaning relation of co-speech gestures.

In this study, we investigated the relationship between maternal gaze at the infant's face and typical verbal measurement of mind-mindedness in free-flowing interactions. Forty 11- to 13-month-old infants and their mothers participated in the study; the mothers were asked to wear a head-mounted eye tracker to measure their gaze during infant-mother free-play interactions. We measured the proportion of time mothers looked at the infant's face when it was present in the mother's field of view and examined the relationship between the face-looking proportion and verbal measurement of mothers' mind-mindedness. Mothers who displayed appropriate mind-related comments looked at the faces of their infants more frequently. Moreover, their looking was coordinated in a timely manner with appropriate mind-related comments compared with other comments.

However, successful attention to shape (shape bias) is dependent on other factors, including children's vocabulary size as well as opportunities for object exploration. The current study explored the combined impact of both vocabulary and object exploration on attention to shape and their cascading impact on retention of object labels. Here, 336 17-to-30-month-old children completed a Novel Noun Generalization (NNG) task and were tested on retention of exemplar name-object pairings. Children in a pre-familiarization condition physically explored objects before every trial; children in a no-familiarization condition did not. Vocabulary (via MacArthur-Bates Communicative Development Inventory) significantly predicted attention to shape, and higher rates of shape-match exploration yielded a stronger shape bias. However, object exploration did not impact NNG performance or retention, and children struggled to retain word-referent mappings. Though attention to shape is thought to support learning, exploratory analyses revealed that children's NNG performance did not predict retention. The results suggest that vocabulary significantly influences word learning processes but object exploration may not offer support. Future research should consider how task demands and other cognitive abilities impact word learning.</p>\u0000 </div>","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"30 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cross-sectional study was conducted using a convenience sample of 183 children; a historical control group of Costa Rican children (<i>n</i> = 171) was also included.

Significant differences were found when comparing the risk of development delay, particularly in the overall score and the fine motor domain score. The probability of overall delay was associated with the child's sex, age, maternal education level and whether the primary caregiver role was shared by both parents or fulfilled by a single parent. In Costa Rica, the development of children assessed post-pandemic was lower than that of children assessed pre-pandemic. The probability of these delays was associated with growing up during the pandemic, child's sex, and families' Socioeconomic Development Index.
