Abstract

Visual working memory (VWM) emerges in the first year of life and has far-reaching implications for academic and later life outcomes. Given that caregivers play a significant role in shaping cognitive function in children, it is important to understand how they might impact VWM development as early as infancy. The current study investigated whether caregivers’ efficiency of regulating inhibitory control was associated with VWM function in their infants. Eighty-eight caregivers were presented with a Go-NoGo task to assess inhibitory control. An efficiency score was calculated using their behavioural responses. Eighty-six 6-to-10-month-old infants were presented with a preferential looking task to assess VWM function. VWM load was manipulated across one (low load), two (medium load) and three (high load) items. Functional near-infrared spectroscopy was used to record brain activation from caregivers and their infants. We found no direct association between caregiver efficiency and infant VWM behaviour. However, we found an indirect association - caregiver efficiency was linked to infant VWM through left-lateralized fronto-parietal engagement. Specifically, infants with low efficiency caregivers showed decreasing left-lateralized parietal engagement with increasing VWM performance at the medium and high loads compared to infants with high efficiency caregivers, who did not show any load- or performance-dependent modulation. Our findings contribute to a growing body of literature examining the role that caregivers play in early neurocognitive development.

照顾者的抑制控制对婴儿视觉工作记忆的影响

视觉工作记忆（VWM）出现于儿童出生后的第一年，对其学业和日后的生活有着深远的影响。鉴于照顾者在塑造儿童认知功能方面扮演着重要角色，了解他们如何影响婴儿时期的视觉工作记忆发展就显得尤为重要。本研究调查了照顾者调节抑制控制的效率是否与婴儿的VWM功能有关。研究人员向 88 名照顾者布置了一项 Go-NoGo 任务，以评估其抑制控制能力。根据他们的行为反应计算出效率分数。86 名 6 至 10 个月大的婴儿接受了优先寻找任务，以评估 VWM 功能。VWM 负荷在一个（低负荷）、两个（中等负荷）和三个（高负荷）项目中进行调节。我们使用功能性近红外光谱记录了照顾者及其婴儿的大脑激活情况。我们发现，照顾者的效率与婴儿的 VWM 行为之间没有直接联系。但是，我们发现了一种间接的关联--照顾者的效率通过左侧前顶叶的参与与婴儿的暴力记忆行为相关联。具体来说，在中负荷和高负荷下，低效能照料者的婴儿表现出左侧顶叶参与度的下降，而高能效照料者的婴儿则没有表现出任何与负荷或表现相关的调节。越来越多的文献研究了照料者在婴儿早期神经认知发展中所扮演的角色，我们的研究结果为这些文献的研究做出了贡献。

期刊介绍： Infant Behavior & Development publishes empirical (fundamental and clinical), theoretical, methodological and review papers. Brief reports dealing with behavioral development during infancy (up to 3 years) will also be considered. Papers of an inter- and multidisciplinary nature, for example neuroscience, non-linear dynamics and modelling approaches, are particularly encouraged. Areas covered by the journal include cognitive development, emotional development, perception, perception-action coupling, motor development and socialisation.
