Abstract:
Overarching theories such as the interactive specialization and maturational frameworks have been proposed to describe human functional brain development. However, these frameworks have not yet been systematically examined across the fMRI literature. Visual processing is one of the most well-studied fields in neuroimaging, and research in this area has recently expanded to include naturalistic paradigms that facilitate study in younger age ranges, allowing for an in-depth critical appraisal of these frameworks across childhood. To this end, we conducted a scoping review of 94 developmental visual fMRI studies, including both traditional experimental task and naturalistic studies, across multiple sub-domains (early visual processing, category-specific higher order processing, naturalistic visual processing). We found that across domains, many studies reported progressive development, but few studies describe regressive or emergent changes necessary to fit the maturational or interactive specialization frameworks. Our findings suggest a need for the expansion of developmental frameworks and clearer reporting of both progressive and regressive changes, along with well-powered, longitudinal studies.
摘要:
已经提出了诸如交互式专业化和成熟框架之类的总体理论来描述人类功能性大脑发育。然而,这些框架尚未在fMRI文献中进行系统检查.视觉处理是神经影像学中研究最充分的领域之一,在这一领域的研究最近已经扩展到包括自然主义范式,以促进在年轻年龄范围内的研究,允许在整个童年对这些框架进行深入的批判性评估。为此,我们对94项发育性视觉功能磁共振成像研究进行了范围审查,包括传统的实验任务和自然主义研究,跨多个子域(早期视觉处理,特定类别的高阶处理,自然主义视觉处理)。我们发现跨域,许多研究报告了逐步发展,但是很少有研究描述适应成熟或交互式专业化框架所必需的回归或紧急变化。我们的研究结果表明,需要扩展发展框架,并更清晰地报告渐进和回归变化,随着动力良好,纵向研究。
