J.N.C. 接受西方心理服务的版税, 用于社会反应量表 (SRS) 的商业分布, 这是30月到成年后的自闭症特征的定量测量。其余的作者没有什么可透露的。

以上的例子分析表明, vrRSB 的强大的心理特性作为一个定量的幼儿测量 RSB。在 vrRSB 上的分数显示了一些类似的特点, SRS, 一个良好的验证措施的 RSB 为较年长的儿童3, 包括持续评分分布在一般人群, 遗传力的证据, 并能够区分无 ASD 的儿童 (在 vrRSB 试验中)。vrRSB 分数在18和24月的年龄与36月的 SRS 评分相关, 证实 RSB 的特征性稳定性在幼儿期是可衡量的。因此, vrRSB 代表了 SRS 和第一仪器的有效向下扩展, 对我们的知识, 提供了一个维度测量 RSB 量化个体差异的典型和超发展的幼儿。这种能力与像 M 聊天和 CSBS 这样的筛选机相比, 它采用了一种分类方法来风险的 ASD 或其他延迟19,20 , 并没有专门索引 RSB。vrRSB 的实施可以提高早期干预的效率, 通过促进对核心 asd 症状变化的快速评估, 这可能显示出与 asd 的其他损害范围 (如自适应功能) 相比有明显的反应。此工具还具有简短、可访问性和适用于多种管理选项的优点, 包括红帽子中的完全开发的在线选项, 这些都适合临床和研究设置。除了密苏里的研究人口在这里报告, 我们的团队已经成功地管理这一调查, 主要是拉美裔的双胞胎人口, 结果显示可比较的心理特性 (未公布的数据, 哈里斯, B., 2017)。因此, 这种工具适用于不同的人群, 并且很容易被翻译成其他语言, 特别是当解释得分锚的社会行为不依赖于口语时。
我们采用了两种方法来克服照顾者报告 RSB 在幼儿中的内在挑战: a) 调整 SRS 项目的子集, 使之适合学步儿童和 b) 实施录像计分锚, 以提供照顾者评分的参考框架。这些策略允许视频参考评分描述社会沟通, RSB 的中心组成部分, 和更广泛的 RSB 总分涵盖社会沟通和限制重复行为, 两个核心症状领域的 ASD。两个分数都证明了有用的测量属性。视频参考评分, 通过使用一个单一的参考儿童的视频在所有年龄的评估, 设计是敏感的变化 RSB 在学步期间, 和所有分数, 它显示了最大的效果大小, 改善 RSB 从18个月到24月。这一评分也比 RSB 总分更强地与表达语言相关, 这与这一尺度对社会交际的关注是一致的。在 RSB 总分的情况下, 纳入与 RSB 和 ASD 相关的特征的 SRS 项目与更强的测试重测可靠性和更高的相关性与36月的总 SRS 评分;这些观察与视频参考评分对社会沟通增量变化的敏感性保持一致。视频参考和 RSB 总分均显示高单卵双生子双孪生和谐, 这意味着测量误差低和可靠性强, 同时证实了良好的测试-重测可靠性, 这可能是易受由于18岁至24月之间的快速发展变化, 低估。此外, 在飞行员测试中, 视频参考和 RSB 总分的杰出儿童与无 ASD。这一差异的影响大小, 虽然很大的两个评分, 是稍微更大的 RSB 总分, 这使机会, 以捕获自闭症特征的变化, 通过更多的项目和覆盖的 ASD 症状域 (即,限制重复行为, 除了社会沟通)。然而, 在视频参考评分中也观察到了强烈的效果大小, 这表明它在幼儿中作为一种非常简短的定量的 ASD 筛查措施的潜在可行性。
这项议定书取得成功的一个关键步骤是适当挑选告密者, 他们必须有足够的经验与儿童有能力评价儿童的 RSB 水平。到目前为止, 我们已成功地与父母作为告密者, 虽然这项调查也适用于其他护理人员, 如日托提供商或其他家庭成员经常与儿童接触 (即,不少于6小时在过去的一个月里, 与孩子互动或看着孩子与他人互动)。应提醒调查受访者观看完整的视频, 以便评分锚提供一个统一的标准, 在评分人, 并有助于提前通知应答者, 允许 15-20 分钟查看视频, 并完成问卷.如果调查是在线管理的, 记录在调查中花费的时间对于质量控制是有帮助的, 因为调查完成得太快引起了对有效性的担忧。最后, 由于评分的多个步骤提供了一个错误的机会, 我们建议使用自动评分算法和交叉检查分量与总分。
vrRSB 的一个局限性是, 在年龄较长的视频参考项目中, 有可能产生地板效应, 因为蹒跚学步的幼儿30月后可能比19月前的得分锚更能显示出更先进的社交交流。因此, 在老年时期, RSB 总分有望在 RSB 中占据更具代表性的变异。此外, 由于评分锚显示了强大的社会沟通能力, 一些照顾者可能倾向于对他们的孩子的评分与得分锚在所有项目, 而不是考虑孩子和锚之间的差异。我们的研究结果, 包括广泛的分数分布和视频参考评分对发展变化的敏感性, 表明这不是一个主要的问题, 在这个样本;尽管如此, vrRSB 的后续迭代可能会探索使用不同级别的 RSB 的多个记分锚, 以及反向得分的视频引用项目, 以检查响应的概念一致性。
未来的方向包括测试 vrRSB 在和没有 ASD 的儿童的较大样本, 以确定该措施的心理特性, 并确定 vrRSB 评分预测 ASD 风险的程度。更大的示例还将有助于减少数据的方法, 以便通过删除 RSB 中的差异低的项目来改进仪器。从方法论的角度看, 有希望的视频参考评分的心理支持视频评分锚在提高行为评分的可靠性和有效性的一般效用。一个婴儿评分锚可以切实允许进一步向下扩展的 RSB 措施, 以更年轻的幼儿和婴儿, 这可以提高及时转诊的早期干预和扩大典型和非典型社会的特征发展轨迹。总之, vrRSB 为改善 ASD 风险的临床评估和干预反应提供了重要的机会。vrRSB 的能力, 检测 RSB 的尺寸变化, RSB 的变化, 以及遗传对 RSB 的影响, 当 asd 出现时, 也重要的是要澄清早期的影响, 基因和环境对 RSB, 这可以指导未来治疗的 asd 和相关疾病。

一个先决条件为社会能力的发展是相互社会行为 (RSB), 规范性能力参与情感上适当, 社会上有需要的行为与其他1。RSB 的中断与社会沟通、人际意识、社会兴趣和参与的显著缺陷有关, 是自闭症频谱紊乱 (ASD) 的一个定义特征。这种可遗传的神经发育条件, 在社会和适应功能上呈现出广泛的损害范围, 一般由幼儿期产生, 并能对早期干预作出反应。因此, RSB 在早期生活中的量化对于 ASD 风险的临床评估以及社会能力典型发展的表征都具有重要意义。
社会反应量表 (SRS) 是 RSB 30 月以上儿童适用的快速定量评分表。这个看护人-报告的措施是利用受访者在自然主义情况下对孩子的累积观察, 以获得 RSB 的细微评价。项目查询评分者对儿童社会沟通缺陷程度和限制性重复行为的印象, 即 ASD2的两个核心症状域, 从而为 RSB 中的量化缺陷编制索引。与 SRS 的广泛研究证实了其强大的心理测量属性3, 包括一个连续的, 单一的评分分布, 其中包含了一般人群的变化, 同时也区分个人与 ASD4 ,5。RSB 的定量变化表现为纵向稳定性6, 与行为特征一致;与自适应函数7的区别, 在 ASD 中的另一个显著方面是缺陷;并且是可继承的5,8,9,10,11, 支持 RSB 与 ASD 相关的遗传学和神经生物学的相关性。
由于 SRS 只延伸到30月的年龄, 需要一个可替代的快速、定量的 RSB 为幼儿提供一个) 量化 asd 风险的早期迹象, b) 跟踪对 asd 早期干预措施的反应。然而, RSB 的测量是复杂的, 在社会交际能力的实质性的个体间差异, 这可能是很难区分可靠的基于书面描述的评分。此外, 照顾者的印象可能会降低一致性, 由于解释有限的语言输出在幼儿的固有主观性, 幼儿行为对情境和环境的敏感性, 以及在一个多产的发展时期, 社会能力的加速进步。
为了解决这些方法上的挑战, 我们制定了相互社会行为的视频参考评分 (vrRSB), 这是为儿童设计的 RSB 的定量指标, 为 18-30 月的年龄12。我们用两种策略来表示 RSB 的特征性连续性, 同时赋予 RSB 早期发育变化的敏感性。首先, 为了促进 vrRSB 和 srs 之间的同源性, 我们从 srs 中调整了一个项目的子集, 使它们在发育上适合于幼儿。第二, 我们结合了一系列新颖的, 独特的视频参考项目, 其中照顾者评定他们的孩子的社会交往行为相比, 一个录像的儿童作为得分锚。此方法在参考效果的框架上进行了计算, 其中提供附加的上下文信息给评分人提高行为特征度量的可靠性和有效性13,14。在这里, 一个可视的参考框架提供了一个3分钟的视频蒙太奇一个典型的发展19月的老显示强大的社会沟通技巧, 同时从事与成人的戏剧基础的互动。由于 RSB 的各个方面在个人15、16中高度相关, 因此该视频的特点是对单个儿童的多面视图, 而不是几个儿童的简短剪辑, 以增强生态有效性。以前的研究还支持视频参考方法的生态学有效性, 因为在临床诊断之前, 可以在录像观察中检测到 ASD 的细微迹象17,18。选定的视频段以视觉方式突出显示了社会沟通的特征, 包括转乘、参与动机和对社会和情感线索的响应1, 从而确保 RSB 的基本方面的内容有效性, 并口语使用限制为避免属性语言能力 RSB 的评分。
根据我们的知识, 目前还没有其他的 RSB 的简单措施来衡量 RSB 在一般人群和 ASD 或其他社会延迟情况下的尺寸变化。已建立的照顾者-报告检查室的 ASD 和相关的延迟, 如幼儿的自闭症核对表 (M 聊天)19或通信和符号行为比例 (CSBS)20一般由项目组成指示是否已经实现了行为里程碑, 并且没有明确地设计来量化社会能力的微妙变化。此外, 与 vrRSB 不同的是, 这些仪器并不特定于 RSB, 也不用于评价核心自闭症症状的水平 (即,社会交往中的损害和受限制的重复行为)。观察性评估, 如自闭症诊断观察计划21, 已制定, 以协助诊断;然而, 这些通常是时间密集型的, 历时 40-60 分钟, 需要训练有素的评分者, 限制其在某些临床设置的可行性。不需要进行任何培训来完成 vrRSB, 使其适合与照顾者、服务提供者和其他有足够的最近经验观察儿童的自然主义社会互动和谁理解书面英语的人使用。该措施, 包括3分钟的视频, 是简短的, 需要 15-20 分钟, 并易于管理的人或远程, 因为它可以邮寄给参加者或完成在线22。因此, vrRSB 的简洁、可获取性和灵活性有助于其在研究、临床和教育环境中的实施, 以便在较早的年龄之前获得对 RSB 的连续、定量测量。

相互的社会行为 (RSB), 一种早期涌现的社会应急能力--这是社会学习和社会能力的基础--被假定在自闭症频谱紊乱 (ASD) 中被打乱。在幼儿期, 当 asd 的核心症状经常出现时, 量化全系列 RSB 的能力, 对于评估 asd 的早期风险、表征社会发展以及跟踪早期干预措施的反应至关重要。然而, RSB 的重要参数--特别是在语言发展之前--可以是微妙的, 难以用基于问卷的方法来描述。为了应对这一挑战, 我们开发了一个测量 RSB 的数量变化的系统 (年龄 18-30 月), 它不仅纳入了护理人员的标准调查表数据, 而且还包含了一套新的视频参考项目, 通过该方法,答辩人将一个受访者的行为与在一个幼儿的短片中所观察到的, 表现出高度胜任的社会沟通水平。对这一措施的测试在一个普通的人口样本双胞胎证实, 视频引用的项目和 RSB 总分 (视频引用的项目加上非视频参考项目) 显示单一, 连续分布, 强大的内部一致性, 显著保护个体差异, 极高的遗传力。此外, 在儿童早期发展过程中, 视频参考项目对于量化社会交往中 RSB 的一个主要因素的增量变化特别敏感。分数在 vrRSB 清楚地被区分的孩子与和没有 ASD, 并且这些数据包括初步证实这个有希望的方法定量早期的 RSB-跨分段, 随着时间, 并且作为早期干预的作用。

vrRSB 在156双双胞胎对例流行病学被测试了从密苏里家庭记数器确定了作为早期的相互社会行为研究的一部分, 前瞻性, 纵向研究RSB12 的发展。我们选择了一个双胞胎的研究设计, 以检查 vrRSB 是否能检测到 RSB 中的人群中的个体差异, 以及这种变异是否是可遗传的。这两种功能都已在较年长的儿童5、8中显示, 并且是评估 vrRSB 在 RSB 中捕获基因信息差异的能力的关键, 这与典型和非典型发展.
照顾者在18、24、36和48月的年龄完成对双胞胎的行为措施;vrRSB (主要是硬拷贝版本, 作为在线版本在研究以后开发) 收集了在18和24月时间点。该样本主要是高加索 (80.1%) 和非西班牙裔 (91.6%), 类似密苏里人口的23, 而平均每年家庭收入的样本 ($ 60001 $ 9万) 高于密苏里 ($ 47200)。与会者对调查的非正式反馈通常是积极的, 95% 以上的返回调查正确完成。为了考虑双数据的非独立性, 对可靠性、行为相关性和纵向差异的分析包括随机选择的一对双胞胎的数据。一个孩子, 谁经历了发展的回归, 最终接受了社区诊断的 ASD, 被排除在这两个分析。
视频引用的分数和 RSB 总分在一般人口样本 (图 1) 的18和24月中显示了连续的、单一的分布。对于视频参考评分, 更大的优势, 较低的分数在24月的年龄提出了轻微的地板效应, 由于更先进的发展 (更高的分数表明较少 RSB)。RSB 总分的分布, 就像 SRS3 的一样, 是右偏斜的, 反映了 RSB 中有大量赤字的个人的小部分。相似的比分发行在一个独立样品被观察了在主要西班牙裔, 双语双胞胎从加利福尼亚 (未发表的数据, 哈里斯, B., 2017)。
在18月 (克隆巴赫系数的 alpha 视频参考评分 =. 841, p < 001, 视频参考项目和 RSB 总分的内部可靠性良好;克隆巴赫系数的 alpha RSB 总分 =. 879, p < 001) 和24月 (克隆巴赫系数的 alpha 视频参考分数 = 881, p < 001;克隆巴赫系数的 alpha RSB 总分 = 868, p < 001)。强烈的内部一致性表明, 这些项目指数代表了整个学步的凝聚力结构。
按组内相关系数 (ICCs; 双向混合单指标), 根据18和24月的时间点获得的分数计算测试的可靠性。在视频参考评分 (ICC (31) = 中, 观察到了良好的6月测试复验可靠性. 505、p < 001、图 2a), 并观察到 RSB 总分 (ICC (31) = 735、p < 001 的强测试重测可靠性;图 2b)。
除了演示测试重测的可靠性, 并通过扩展, 在 RSB 中检测与品质相关的一致性的能力, vrRSB 的一个重要目标是跟踪 RSB 在发展方面的进展。视频参考和 RSB 总分都能检测到 RSB 随着时间的推移而显著的改善, 在18个月 (表 2) 之间, 分数降低 (分数表示更好 RSB)。视频参考分数显示了更大的效果大小为这些下降 vs. RSB 总分 (科恩的 d = 0.66 vs 0.48)。对于非视频引用的项目 (表 2) 的单独计算, 这些项未设计为跟踪更改, 显示了这些项目的效果大小 (科恩的 d = 0.22)。
由于 RSB 的变异已被证明是遗传的在老人口, 双胞胎双胞胎和谐被计算为录影参考的比分和 RSB 总比分在18月 (表 3)。在单卵双生子 (相同) 双胞胎中, 与卵 (异卵) 双胞胎 (组内) 的较高的相关性, 他们的基因材料的平均一半, 与 RSB 的遗传力是一致的。和谐为单卵双生子双胞胎是相当高的, 并且在许多情况下大致加倍那些卵双胞胎, 支持一个强有力的作用为基因影响。注意, 单卵双生子双和谐也表示可能测量误差的上限。对于两个 vrRSB 分数, 可能的测量误差小于9% 在整个双样本的水平 (错误 = 1-单卵双生子双胞胎和谐)。
作为对并发有效性的测试, 我们研究了 vrRSB 中的 "M 聊天"、"ASD" 筛选的分数的相关性。正相关与 vrRSB 捕获与 ASD 风险相关的变化的能力 (视频参考评分: r =. 444, p < 001;RSB 总分: r = 654, p < 001)。我们还获得了 vrRSB 分数和表达式词汇 (分数) 之间的相关性, 由麦克阿瑟-贝茨的交际发展清单 (简称为24) 来衡量, 考虑到语言和社会之间的预期关系。通信.在视频参考评分 (r =-419, p < 001) 和 RSB 总分 (r =-309, p < 001) 中发现了显著的相关性。
最后, 在先导测试 (表 4) 中, 我们比较了双胞胎的分数, 而没有对 asd 的诊断和儿童的小样本, 无论是对 asd 的社区诊断, 还是自闭症诊断观察计划的自闭症或自闭症评分21(平均年龄 (SD): 24.75 (5.56) 月; 年龄范围:17-33 月)。视频参考评分和 RSB 总分在儿童与无 ASD 之间区分, 效果大小 (科恩的 d) 为-1.39 的视频参考评分和-1.66 的 RSB 总分。对 ASD 核心症状域 (社会沟通: 科恩的 d =-1.58) 项目评分也观察到组差异;限制性的, 重复的行为: 科恩的 d =-1.52)。在定量 RSB 评分水平上, 18 月的视频参考评分和 RSB 总分与36月 SRS 的总分相关 (视频参考评分: r = 298, p = 001;RSB 总分: r = 624, p < 001)。

A Novel Experimental and Analytical Approach to the Multimodal Neural Decoding of Intent During Social Interaction in Freely-behaving Human Infants

Understanding typical and atypical development remains one of the fundamental questions in developmental human neuroscience. Traditionally, experimental paradigms and analysis tools have been limited to constrained laboratory tasks and contexts due to technical limitations imposed by the available set of measuring and analysis techniques and the age of the subjects. These limitations severely limit the study of developmental neural dynamics and associated neural networks engaged in cognition, perception and action in infants performing &#8220;in action and in context&#8221;. This protocol presents a novel approach to study infants and young children as they freely organize their own behavior, and its consequences in a complex, partly unpredictable and highly dynamic environment. The proposed methodology integrates synchronized high-density active scalp electroencephalography (EEG), inertial measurement units (IMUs), video recording and behavioral analysis to capture brain activity and movement non-invasively in freely-behaving infants. This setup allows for the study of neural network dynamics in the developing brain, in action and context, as these networks are recruited during goal-oriented, exploration and social interaction tasks.

This protocol presents a novel methodology for the neural decoding of intent from freely-behaving infants during unscripted social interaction with an actor. Neural activity is acquired using non-invasive high-density active scalp electroencephalography (EEG). Kinematic data is collected with inertial measurement units and supplemented with synchronized video recording.

Behavioral Assessment of Hearing in 2 to 4 Year-old Children: A Two-interval, Observer-based Procedure Using Conditioned Play-based Responses

Collecting reliable behavioral data from toddlers and preschoolers is challenging. As a result, there are significant gaps in our understanding of human auditory development for these age groups. This paper describes an observer-based procedure for measuring hearing sensitivity with a two-interval, two-alternative forced-choice paradigm. Young children are trained to perform a play-based, motor response (e.g., putting a block in a bucket) whenever they hear a target signal. An experimenter observes the child&#39;s behavior and makes a judgment about whether the signal was presented during the first or second observation interval; the experimenter is blinded to the true signal interval, so this judgment is based solely on the child&#39;s behavior. These procedures were used to test 2 to 4 year-olds (n = 33) with no known hearing problems. The signal was a 1,000 Hz warble tone presented in quiet, and the signal level was adjusted to estimate a threshold corresponding to 71%-correct detection. A valid threshold was obtained for 82% of children. These results indicate that the two-interval procedure is both feasible and reliable for use with toddlers and preschoolers. The two-interval, observer-based procedure described in this paper is a powerful tool for evaluating hearing in young children because it guards against response bias on the part of the experimenter.

This paper describes a procedure for measuring hearing sensitivity in 2 to 4 year-old children. Children are trained to perform play-based responses when they hear a target signal. Thresholds are then estimated in a two-interval, two-alternative forced-choice paradigm, based on observations of the child&#39;s behaviors.

Psychophysiological Assessment of the Effectiveness of Emotion Regulation Strategies in Childhood

Effective regulation of emotion is one of the most important skills that develops in childhood. Research interest in this area is expanding, but empirical work has been limited by predominantly correlational investigations of children's skills. Relatedly, a key conceptual challenge for emotion scientists is to distinguish between emotion responding and emotion regulatory processes. This paper presents a novel method to address these conceptual and methodological issues in child samples. An experimental paradigm that assesses the effectiveness with which children regulate emotion is described. Children are randomly assigned to use specific emotion regulation strategies, negative emotions are elicited with film clips, and changes in subsequent psychophysiology index the extent to which emotion regulation is effective. Children are instructed to simply watch the emotion-eliciting film (control), distract themselves from negative emotions (cognitive distraction), or reframe the situation in a way that downplays the importance of the emotional event (cognitive reappraisal). Cardiac physiology, continuously acquired before and during the emotional task, serves as an objective measure of children's unfolding emotional responding while viewing evocative films. Key comparisons in patterns of obtained physiological reactivity are between the control and emotion regulation strategy conditions. Representative results from this approach are described, and discussion focuses on the contribution of this methodological approach to developmental science.

A Within-subjects Experimental Protocol to Assess the Effects of Social Input on Infant EEG

Despite the importance of social interactions for infant brain development, little research has assessed functional neural activation while infants socially interact. Electroencephalography (EEG) power is an advantageous technique to assess infant functional neural activation. However, many studies record infant EEG only during one baseline condition. This protocol describes a paradigm that is designed to comprehensively assess infant EEG activity in both social and nonsocial contexts as well as tease apart how different types of social inputs differentially relate to infant EEG. The within-subjects paradigm includes four controlled conditions. In the nonsocial condition, infants view objects on computer screens. The joint attention condition involves an experimenter directing the infant's attention to pictures. The joint attention condition includes three types of social input: language, face-to-face interaction, and the presence of joint attention. Differences in infant EEG between the nonsocial and joint attention conditions could be due to any of these three types of input. Therefore, two additional conditions (one with language input while the experimenter is hidden behind a screen and one with face-to-face interaction) were included to assess the driving contextual factors in patterns of infant neural activation. Representative results demonstrate that infant EEG power varied by condition, both overall and differentially by brain region, supporting the functional nature of infant EEG power. This technique is advantageous in that it includes conditions that are clearly social or nonsocial and allows for examination of how specific types of social input relate to EEG power. This paradigm can be used to assess how individual differences in age, affect, socioeconomic status, and parent-infant interaction quality relate to the development of the social brain. Based on the demonstrated functional nature of infant EEG power, future studies should consider the role of EEG recording context and design conditions that are clearly social or nonsocial.

This novel protocol is designed to assess the neural bases of social interaction in infants. The paradigm is designed to tease apart how various social inputs such as language, joint attention, and face-to-face interaction relate to infant neural activation. Infant EEG power is recorded during both social and nonsocial conditions.

Portable Intermodal Preferential Looking (IPL): Investigating Language Comprehension in Typically Developing Toddlers and Young Children with Autism

One of the defining characteristics of autism spectrum disorder (ASD) is difficulty with language and communication.1 Children with ASD's onset of speaking is usually delayed, and many children with ASD consistently produce language less frequently and of lower lexical and grammatical complexity than their typically developing (TD) peers.6,8,12,23 However, children with ASD also exhibit a significant social deficit, and researchers and clinicians continue to debate the extent to which the deficits in social interaction account for or contribute to the deficits in language production.5,14,19,25
Standardized assessments of language in children with ASD usually do include a comprehension component; however, many such comprehension tasks assess just one aspect of language (e.g., vocabulary),5 or include a significant motor component (e.g., pointing, act-out), and/or require children to deliberately choose between a number of alternatives. These last two behaviors are known to also be challenging to children with ASD.7,12,13,16
We present a method which can assess the language comprehension of young typically developing children (9-36 months) and children with autism.2,4,9,11,22 This method, Portable Intermodal Preferential Looking (P-IPL), projects side-by-side video images from a laptop onto a portable screen. The video images are paired first with a 'baseline' (nondirecting) audio, and then presented again paired with a 'test' linguistic audio that matches only one of the video images. Children's eye movements while watching the video are filmed and later coded. Children who understand the linguistic audio will look more quickly to, and longer at, the video that matches the linguistic audio.2,4,11,18,22,26
This paradigm includes a number of components that have recently been miniaturized (projector, camcorder, digitizer) to enable portability and easy setup in children's homes. This is a crucial point for assessing young children with ASD, who are frequently uncomfortable in new (e.g., laboratory) settings. Videos can be created to assess a wide range of specific components of linguistic knowledge, such as Subject-Verb-Object word order, wh-questions, and tense/aspect suffixes on verbs; videos can also assess principles of word learning such as a noun bias, a shape bias, and syntactic bootstrapping.10,14,17,21,24 Videos include characters and speech that are visually and acoustically salient and well tolerated by children with ASD.

Portable Intermodal Preferential Looking IPL: Investigating Language Comprehension in Typically Developing Toddlers and Young Children with Autism

A reliable home-based way to assess the language comprehension of very young typically developing children, as well as those with autism, is described. The method analyzes children's eye gaze while viewing side-by-side images but hearing an audio that matches only one image. Stimuli are designed with young participants in mind.

An Electrophysiology Protocol to Measure Reward Anticipation and Processing in Children

We present a protocol designed to measure the neural correlates of reward in children. The protocol allows researchers to measure both reward anticipation and processing. Its purpose is to create a reward task that is appropriate for young children with and without autism while controlling reward properties between two conditions: social and nonsocial. The current protocol allows for comparisons of brain activity between social and nonsocial reward conditions while keeping the reward itself identical between conditions. Using this protocol, we found evidence that neurotypical children demonstrate enhanced anticipatory brain activity during the social condition. Furthermore, we found that neurotypical children anticipate social reward more robustly than children with autism diagnoses. As the task uses snacks as a reward, it is most appropriate for young children. However, the protocol may be adapted for use with adolescent or adult populations if snacks are replaced by monetary incentives. The protocol is designed to measure electrophysiological events (event-related potentials), but it may be customized for use with eye-tracking or fMRI.

This protocol is designed to measure reward anticipation and processing in young children with and without autism. Specifically, the protocol is designed to study the neural correlates of reward during social and nonsocial conditions while controlling for reward between conditions.

Comparing Eye-tracking Data of Children with High-functioning ASD, Comorbid ADHD, and of a Control Watching Social Videos

Children with autism spectrum disorders (ASD) are known to have sensory-perceptual processing deficits that weaken their abilities to attend and perceive social stimuli in daily living contexts. Since daily social episodes consist of subtle dynamic changes in social information, any failure to attend to or process subtle human nonverbal cues, such as facial expression, postures, and gestures, might lead to inappropriate social interaction. Traditional behavioral rating scales or assessment tools based on static social scenes have limitations in capturing the moment-to-moment changes in social scenarios. An eye-tracking assessment, which can be administered in a video-based mode, is therefore preferred, to augment clinical observation. In this study, using the single-case comparison design, the eye-tracking data of three participants, a child with autism spectrum disorder (ASD), another with comorbid attention deficit-hyperactive disorder (ADHD), and a neurotypical control, are captured while they view a video of social scenarios. The eye-tracking experiment has helped answer the research question: How does social attention differ between the three participants? By predefining areas of interest (AOIs), their visual attention on relevant or irrelevant social stimuli, how fast each participant attends to the first social stimuli appearing in the videos, for how long each participant continues to attend to those stimuli within the AOIs, and the gaze shifts between multiple social stimuli appearing concurrently in the same social scene are captured, compared, and analyzed in a video-based eye-tracking experiment.

This is a qualitative comparative case study analysis of eye-tracking data on the first moments of social video scenes as viewed by three participants: one with autism spectrum disorder, one with comorbid attention deficit-hyperactive disorder, and one neurotypical control.

Modeling Verbal Behavior Deficits with the Stimulus Control Ratio Equation, SCoRE

Verbal operant analyses are the extension of functional analysis technology to the field of verbal behavior, of particular relevance to autism spectrum disorders and associated developmental disabilities. Similarly, a verbal operant analysis carefully controls specific environmental factors that influence language, and measures strength of responding across four verbal operant classes: tact, mand, echoic, and sequelic. The frequency of each independent verbal operant is then measured against one another using the stimulus control ratio equation (SCoRE) to summarize the relative strength of the speaker&#8217;s repertoire. The verbal behavior SCoRE yields a statistic that can be compared against itself (e.g., for the purposes of pre/post testing) or against others (e.g., for the purposes of randomized controlled trials). The results of this evaluation provide an individualized hierarchy for diverging stimulus control across the verbal operants, from which a treatment plan for errorless language learning may be prescribed.

This article describes the procedures for conducting a verbal operant analysis (VOA), calculating the stimulus control ratio equation (SCoRE), and developing individualized verbal behavior treatment plans, specifically significant to address the deficits characteristic of autism.

Exploring Infant Sensitivity to Visual Language using Eye Tracking and the Preferential Looking Paradigm

We discuss the use of the preferential looking paradigm in eye tracking studies in order to study how infants develop, understand, and attend to the world around them. Eye tracking is a safe and non-invasive way to collect gaze data from infants, and the preferential looking paradigm is simple to design and only requires the infant to be attending to the screen. By simultaneously showing two visual stimuli that differ in one dimension, we can assess whether infants show different looking behavior for either stimulus, thus demonstrating sensitivity to that difference. The challenges in such experimental approaches are that experiments must be kept brief (no more than 10 min) and be carefully controlled such that the two stimuli differ in only one way. The interpretation of null results must also be carefully considered. In this paper, we illustrate a successful example of an infant eye tracking study with a preferential looking paradigm to discover that 6-month-olds are sensitive to linguistic cues in a signed language despite having no prior exposure to signed language, suggesting that infants possess intrinsic or innate sensitivities to these cues.

Eye tracking studies using a preferential looking paradigm can be used to study infants&#39;&#160;emerging understanding of, and attention to, their external visual world.

An Automated Method for Assessing Visual Acuity in Infants and Toddlers Using an Eye-Tracking System

Visual acuity measurement is an important visual function test to perform in infancy and childhood. However, accurate visual acuity measurement in infants is difficult because of deficiencies in their communication ability. This paper presents a novel automated method to assess visual acuity in children (5-36 months old). This method, the automated acuity card procedure (AACP), uses a webcam for eye tracking and recognizes children's watching behaviors automatically. A two-choice preferential-looking test is performed when the tested child watches the visual stimuli shown on a high-resolution digital display screen. When the tested child watches the stimuli, their facial pictures are recorded by the webcam. These pictures are used by the set computer program to analyze their watching behavior. With this procedure, the child's eye movement responses to different stimuli are measured, and their visual acuity is assessed without communication. By comparing the results with grating acuity obtained by Teller Acuity Cards (TACs), AACP performance is deemed comparable to that of TACs.
