In this study, we examined the relative benefits of using video-based instruction, compared to in-person instruction for young children within the domain of spatial language—a domain known to be closely associated with children’s later academic success. We asked whether children would learn as readily from video instruction as they do from in-person instruction, and whether we can improve children’s learning further by instructing them in both gesture and speech than in speech-alone. We predicted that children would show no effect of instruction medium (live, video) but an effect of modality (with gesture, without gesture), with better learning outcomes when instructed with gesture. We tested these predictions by examining the responses of 3- to 5-year-old children to questions about different spatial descriptions—half with gesture and half without gesture—using either a video or a live instruction. Our analysis showed no effect of instructional medium or modality, suggesting that children learn equally well in video and live instruction—whether it is presented with gesture or without gesture.

We investigated the progression of episodic memory binding in 79 preschool children (44 boys, 35 girls, aged 3–6 years) using a nonverbal object placement task that required the memory of 'what' (objects), 'where' (space), and 'when' (temporal order) information. In each trial, the child watched as the experimenter hid three distinct objects into three of five cups on a tabletop apparatus; after an interference task, children were asked to re-enact the sequence. We set the association of space and objects in conflict with their temporal order by handing the objects to the children during the re-enactment phase either in the same or shuffled order. Although children showed an overall improvement in memory with age, younger children’s pattern of errors in the shuffled order condition revealed that they often responded according to the temporal sequence of locations instead.

No discernible reaction time pattern emerged for the 4-year-olds. Instead of a linear increase in reaction time with angular disparity typical for mental rotation tasks, the 5-year-olds’ reaction times reflected a recapitulation of actual biomechanical movements needed to align their hands with the stimulus.

These findings are in line with the view that cognition is ontogenetically grounded in the sensorimotor system and becomes increasingly abstract with development.

This preliminary study investigates L1 word learning in French kindergarten children (ages 5–6), focusing on the impact of gestures compared to pictures. Using a within-subject design, 30 children learned 10 new words across two learning conditions: gesture reproduction and picture presentation. The main aim was to assess whether reproducing gestures during learning is more effective than viewing pictures, based on the idea that motor engagement could improve both phonological and semantic memory representations, thereby supporting both fast and slow mapping processes. To evaluate learning outcomes, children completed comprehension (word recognition), production (free recall and naming), and definition tasks to assess the depth of word knowledge. Additional measures included children’s initial vocabulary levels and manual dexterity to examine their potential influence on learning performance, particularly in the gesture condition. Findings revealed that the effectiveness of gesture-based learning varied depending on the task.

Around 5.5 years, children indicated that others should select the smaller resource (paper and foods) when this would reduce waste, showing that they think others should minimize material waste. For example, when a person could create a paper snowflake using either a larger or smaller sheet of paper, children aged 5.5 and older recommended using the smaller sheet (reducing the amount of paper wasted as scraps).
