BACKGROUND
There are strong parallels between early childhood and adolescent behavior problems. However, we do not know if behavioral symptoms associate with neurocognitive processes in very young children as they do in older children.
METHODS
We studied a population-based birth cohort of children (N = 1,950) whose developmental trajectories of physical aggression and hyperactivity were assessed between the ages of 17 and 41 months. We measured the following neurocognitive abilities at 41 months of age: Receptive vocabulary, visuospatial organization, and short-term memory.
RESULTS
After controlling for other neurocognitive abilities, frequent physical aggression was related specifically to receptive vocabulary deficits (p < .0001) while frequent hyperactivity was related specifically to deficits of visuospatial organization (p < .0001). The pattern of associations was robust despite controls for socioeconomic and perinatal status.
CONCLUSIONS
The different neurocognitive correlates of physical aggression and hyperactivity problems observed during adolescence are apparent in early childhood. Whereas physical aggression problems are associated with language deficits, hyperactivity problems are related to non-verbal deficits.
背景
幼儿期和青少年期的行为问题存在诸多相似之处。然而，我们并不清楚行为症状在幼儿中是否像在大龄儿童中那样与神经认知过程相关。
方法
我们对一个基于人群的儿童出生队列（N = 1950）进行了研究，这些儿童在17至41个月大时接受了身体攻击和多动的发育轨迹评估。我们在41个月大时测量了以下神经认知能力：接受性词汇、视觉空间组织和短期记忆。
结果
在控制了其他神经认知能力后，频繁的身体攻击行为与接受性词汇缺陷显著相关（p <.0001），而频繁的多动行为与视觉空间组织缺陷显著相关（p <.0001）。尽管对社会经济和围产期状况进行了控制，但这种关联模式依然稳固。
结论
青少年期观察到的身体攻击和多动问题的不同神经认知关联在幼儿期就已显现。身体攻击问题与语言缺陷相关，而动多问题与非语言缺陷相关。
