迄今为止，很少有研究比较和对比用于测量持续注意力的不同技术。我们选取了42个发育正常的11个月大的婴儿。我们使用六种不同的测量范式（四种基于屏幕的，两种自然的）来评估峰值注视持续时间。因子分析表明，四个基于屏幕的任务和两个自然任务映射到不同的因素。我们的研究结果质疑基于屏幕的任务的个体差异如何在更生态有效的环境中表现出来。趋同的研究指出了研究生命早期持续注意力的个体发生的重要性，但迄今为止很少有研究比较和对比可用于测量持续注意力的不同技术。在这里，我们比较了用于评估持续注意的一个参数的方法，即婴儿对新刺激的峰值注视持续时间。我们的重点是评估在不同的测量技术中，峰值注视持续时间的个体差异是否稳定。在42名11个月大的典型发育婴儿的单一队列中，我们使用六种不同的测量范式（四种基于屏幕的，两种自然的）来评估峰值注视时间。零级相关表明，四种基于屏幕的范式的峰值注视持续时间的个体差异是稳定的，但基于屏幕的范式和自然主义范式的峰值注视持续时间之间没有相关性。对视峰时长因变量进行因子分析，确定了两个因素。所有四个基于屏幕的任务都加载到第一个因素上，但两个自然任务没有关联，而是映射到不同的因素上。我们的研究结果质疑了在基于屏幕的任务中观察到的个体差异是如何在更生态有效的环境中表现出来的。
Little research hitherto has compared and contrasted different techniques available for measuring sustained attention. We took a single cohort of 42 typically developing 11-month-old infants. We assessed peak look duration using six different measurement paradigms (four screen-based, two naturalistic). A factor analysis suggested that the four screen-based tasks and two naturalistic tasks mapped onto separate factors. Our results question how individual differences on screen- based tasks might manifest in more ecologically valid contexts. Convergent research points to the importance of studying the ontogenesis of sustained attention during the early years of life, but little research hitherto has compared and contrasted different techniques available for measuring sustained attention. Here, we compare methods that have been used to assess one parameter of sustained attention, namely infants’ peak look duration to novel stimuli. Our focus was to assess whether individual differences in peak look duration are stable across different measurement techniques. In a single cohort of 42 typically developing 11-month-old infants we assessed peak look duration using six different measurement paradigms (four screen-based, two naturalistic). Zero-order correlations suggested that individual differences in peak look duration were stable across all four screen-based paradigms, but no correlations were found between peak look durations observed on the screen-based and the naturalistic paradigms. A factor analysis conducted on the dependent variable of peak look duration identified two factors. All four screen-based tasks loaded onto the first factor, but the two naturalistic tasks did not relate, and mapped onto a different factor. Our results question how individual differences observed on screen-based tasks manifest in more ecologically valid contexts.
