概括

婴儿语音类发音 (可变性) 在发育群体中是相似的,但自闭症 (ASD) 或发育迟缓 (DD) 的男孩在第一年表现出独特的可变性下降.

科学领域:

发展心理学发展心理学
语音语言病理学语言病理学
儿科神经学儿科神经学

背景情况:

人类婴儿表现出高率的语音类发音 (可变性),明显超过了猿类亲属的发音.
这种声音行为是早期发育和沟通技能的关键指标.

研究的目的:

纵向记录和分析典型发育 (TD) 婴儿,自闭症谱系障碍 (ASD) 婴儿和发育迟缓 (DD) 婴儿的婴儿发声能力.
为了确定这些群体在生命的第一年声调模式的潜在差异.

主要方法:

从302名婴儿身上收集了全天的长度音频录音.
训练有素的编码人员分析了这些录音中的5分钟段,以量化类似语音的发音,哭声和笑声.

主要成果:

所有婴儿组在第一年表现出相似的发声率 (4-5个发声/分钟).
所有组 (TD,ASD,DD) 的男孩表现出比女孩更高的发言能力.
虽然TD婴儿的发言能力保持稳定,但ASD和DD的男孩的发言能力下降,与这些群体中的女孩不同.

结论:

婴儿发言能力在TD,ASD和DD组之间显示了广泛的相似之处.
一个重要的发现是,在被诊断为ASD或DD的男性婴儿中观察到的发声能力下降,这种模式在TD婴儿中不存在.
在有风险的男性中,这种独特的发声轨迹可能会为早期发育轨迹和诊断标记提供见解.

Autism Spectrum Disorder

Autism Spectrum Disorder

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.

Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Modeling in Therapy

Modeling in Therapy

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.

Participant modeling involves therapists demonstrating calm and effective behaviors in...
