How do children's experiences relate to their naturalistic emotional and social processing? Because children can struggle with tasks in the scanner, we collected fMRI data while 4-to-11-year-olds watched a short film with positive and negative emotional events, and rich parent-child interactions (n = 70). We captured broad, normative stressful experiences by examining socioeconomic status (SES) and stressful life events, as well as children's more proximal experiences with their parents. For a sub-sample (n = 30), parenting behaviors were measured during a parent-child interaction, consisting of a picture book, a challenging puzzle, and free play with novel toys. We characterized positive parenting behaviors (e.g., warmth, praise) and negative parenting behaviors (e.g., harsh tone, physical control). We found that higher SES was related to greater activity in medial orbitofrontal cortex during parent-child interaction movie events. Negative parenting behaviors were associated with less activation of the ventral tegmental area and cerebellum during positive emotional events. In a region-of-interest analysis, we found that stressful life events and negative parenting behaviors were associated with less activation of the amygdala during positive emotional events. These exploratory results demonstrate the promise of using movie fMRI to study how early experiences may shape emotional, social, and motivational processes.
儿童的经历如何与他们自然主义的情绪和社会加工相关联？由于儿童在扫描仪中完成任务时可能会遇到困难，我们在4至11岁的儿童观看一部包含积极和消极情绪事件以及丰富亲子互动的短片时收集了功能磁共振成像（fMRI）数据（n = 70）。我们通过考察社会经济地位（SES）和应激生活事件，以及儿童与父母更直接的经历，获取了广泛的、具有代表性的应激经历。对于一个子样本（n = 30），在亲子互动期间测量养育行为，互动内容包括一本图画书、一个具有挑战性的拼图以及玩新奇玩具的自由游戏。我们对积极养育行为（如温暖、赞扬）和消极养育行为（如严厉语气、身体控制）进行了特征描述。我们发现，在亲子互动电影事件中，较高的社会经济地位与内侧眶额皮质的更大活动相关。消极养育行为与在积极情绪事件期间腹侧被盖区和小脑的激活减少有关。在一项感兴趣区域分析中，我们发现应激生活事件和消极养育行为与在积极情绪事件期间杏仁核的激活减少有关。这些探索性结果表明了使用电影功能磁共振成像来研究早期经历如何塑造情绪、社会和动机过程的前景。
