Abstract

This study quantified the spatial exploration of 13 infants born very and extremely preterm (PT) at 4 months corrected age as they learned that moving their feet vertically to cross a virtual threshold activated an infant kick-activated mobile and compared results to 15 infants born full-term (FT) from a previously published study. Spatial exploration was quantified using two general spatial exploration variables (exploration volume, exploration path), two task-specific spatial variables (duration of time in the task-specific region of interest, vertical variance of kicks), and one non-task-specific spatial variable (horizontal variance of kicks). The infants born PT, similar to FT, increased their general spatial exploration and duration in the region of interest and did not change the vertical and horizontal variances of kicks. However, the infants born PT, compared to FT, spent less time in the task-specific region of interest and had a greater non-task-specific horizontal variance throughout the task. This may indicate that infants born PT and FT exhibit similar general spatial exploration, but infants born PT exhibit less task-specific spatial exploration. Future research is necessary to determine the contribution of learning and motor abilities to the differences in task-specific exploration between infants born PT and FT.

早产婴儿在支架式踢腿活动移动任务中表现出任务特异性探索减少。
这项研究量化了13名在4个月校正年龄时出生的极早产(PT)婴儿的空间探索,因为他们了解到垂直移动双脚以越过虚拟阈值会激活婴儿踢腿激活的移动设备,并将结果与之前发表的一项研究中的15名足月出生(FT)婴儿进行了比较。空间探索使用两个通用空间探索变量(探索量、探索路径)、两个特定任务的空间变量(在特定任务感兴趣区域的持续时间、踢球的垂直方差)和一个非特定任务空间变量(踢球的水平方差)进行量化。出生于PT的婴儿,与FT类似,增加了他们在感兴趣区域的一般空间探索和持续时间,并且没有改变踢的垂直和水平变化。然而,与FT相比,出生于PT的婴儿在感兴趣的特定任务区域花费的时间更少,并且在整个任务中具有更大的非特定任务水平方差。这可能表明出生于PT和FT的婴儿表现出相似的一般空间探索,但出生于PT的婴儿表现较少的任务特异性空间探索。未来的研究是必要的,以确定学习和运动能力对出生于PT和FT的婴儿在特定任务探索方面的差异的贡献。

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
