概括
与典型发育的同龄人相比,患有自闭症谱系障碍 (ASD) 的儿童在识别普通话音调时使用语音上下文的程度较低. 像口头智能这样的认知能力也会影响典型发育的儿童的这种上下文效应.
科学领域:
- 心理语言学 心理语言学
- 发展心理学 发展心理学
- 神经发育障碍 神经发育障碍
背景情况:
- 患有自闭症谱系障碍 (ASD) 的人经常表现出不典型的处理上下文信息.
- 关于ASD如何影响语音处理中的上下文线索的整合,特别是在音调语言中,目前的研究有限.
研究的目的:
- 为了调查在普通话说话的儿童和没有ASD的词汇音调识别.
- 检查语音和非语音语境在音调感知中的作用.
- 确定认知能力是否调节有或没有自闭症儿童的背景效应.
主要方法:
- 25名患有自闭症儿童和25名典型发育 (TD) 儿童在言语,非言语和平面非言语语境中识别了普通话的词汇音调.
- 认知评估包括口头智力,非语言智力和工作记忆能力.
主要成果:
- 对于这两组人来说,只在语音环境中观察到上下文效应.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
