1. The Role of Speech and Hearing in Communication | 口语与听力在沟通中的作用

Human communication relies heavily on the production of speech sounds and the auditory perception of those sounds. Spoken language allows us to share thoughts, express emotions and coordinate social activities. Hearing, on the other hand, is the physiological process that converts sound waves into neural signals, enabling us to decode the speaker’s message.

人类的沟通在很大程度上依赖于言语声音的产生和对这些声音的听觉感知。口语使我们能够分享想法、表达情绪并协调社交活动。而听力则是将声波转换为神经信号的生理过程，使我们能够解读说话者的信息。

From a psychological perspective, the interplay between speaking and listening shapes early cognitive development, social learning and even our sense of identity. Researchers in the WJEC specification often explore how infants move from babbling to fluent speech and how hearing impairments can alter the trajectory of language acquisition.

从心理学角度看，说与听的相互作用塑造了早期认知发展、社会学习甚至我们的自我认同感。WJEC 大纲中的研究者经常探索婴儿如何从咿呀学语发展到流利说话，以及听力障碍如何改变语言习得的轨迹。

2. The Building Blocks of Spoken Language | 口语的构成要素

Spoken language can be broken down into smaller units. The smallest distinctive sound units are called phonemes. For example, the word ‘cat’ consists of three phonemes: /k/, /æ/ and /t/. Changing one phoneme can alter the meaning entirely, as in ‘cat’ versus ‘bat’.

口语可以分解为更小的单位。最小的区别性声音单位称为音素。例如，单词 ‘cat’ 由三个音素组成：/k/、/æ/ 和 /t/。改变一个音素就可能完全改变词义，比如 ‘cat’ 和 ‘bat’。

Phonemes combine to form morphemes, the smallest units of meaning. The word ‘cats’ contains two morphemes: ‘cat’ (a free morpheme) and ‘s’ (a bound morpheme indicating plural). Syntax then governs how words are arranged into sentences. Understanding these building blocks helps psychologists analyse both typical and atypical speech development.

音素组合形成词素，即最小的意义单位。单词 ‘cats’ 包含两个词素：’cat’（自由词素）和 ‘s’（表示复数的黏着词素）。句法则支配词语如何排列成句子。理解这些构成要素有助于心理学家分析典型与非典型言语发展。

Phonemes – sound units that distinguish meaning (e.g., /p/ vs /b/)
音素 – 区分意义的声音单位（例如 /p/ 与 /b/）
Morphemes – meaning-carrying units (e.g., ‘un-‘, ‘happy’, ‘-ness’)
词素 – 承载意义的单位（例如 ‘un-‘、’happy’、’-ness’）

3. The Auditory System and Speech Perception | 听觉系统与言语知觉

Speech perception begins when sound waves enter the outer ear and travel through the auditory canal to the eardrum. The vibrations are transmitted via the ossicles in the middle ear to the cochlea in the inner ear, where hair cells convert the mechanical energy into electrical impulses sent to the brain’s auditory cortex.

言语知觉始于声波进入外耳，并通过耳道传到鼓膜。振动经由中耳的听小骨传至内耳的耳蜗，在那里毛细胞将机械能转化为电脉冲，发送至大脑的听觉皮层。

Psychologists are particularly interested in how we segment the continuous stream of speech into discrete phonemes. Coarticulation means that phonemes overlap in natural speech, yet humans are remarkably skilled at categorical perception – hearing physically different sounds as the same phoneme provided they fall within a boundary.

心理学家尤其感兴趣的是，我们如何将连续的语流切分为独立的音素。协同发音意味着在自然言语中音素会重叠，然而人类擅长于范畴性知觉——在声学上不同的声音，只要落在某个边界内，就被听成同一个音素。

Component	Function	部件	功能
Outer ear	Collects and funnels sound waves	外耳	收集和传导声波
Cochlea	Converts vibrations into neural signals	耳蜗	将振动转化为神经信号
Auditory cortex	Processes and interprets speech sounds	听觉皮层	处理并理解言语声音

4. Nature versus Nurture in Speech Development | 言语发展中的先天与后天之争

A central debate in psychology is whether the ability to speak and listen is primarily inherited (nature) or learned from the environment (nurture). Nativists argue that children are born with an innate capacity for language, while empiricists claim that speech is acquired through imitation, reinforcement and social input.

心理学的一个核心争论是：说话和倾听的能力主要是遗传的（先天）还是从环境中学来的（后天）。先天论者认为儿童天生就有语言能力，而经验主义者则主张言语是通过模仿、强化和社会输入习得的。

The WJEC specification expects you to evaluate both sides using evidence. For example, the rapidity and uniformity of language milestones across cultures support nativist ideas, but the variation in vocabulary and accent highlights the role of the environment. Hearing children of deaf parents can also provide insight: their speech development may be delayed if oral input is limited.

WJEC 大纲要求运用证据来评价双方观点。例如，跨文化中语言里程碑的快速性和一致性支持先天论，但词汇和口音的差异则突显了环境的作用。聋人父母所生的健听儿童也能提供深刻见解：如果口语输入有限，他们的言语发展可能会延迟。

5. Chomsky’s Nativist Theory and the Language Acquisition Device | 乔姆斯基的先天论与语言习得装置

Noam Chomsky proposed that every child is born with a biological predisposition to acquire language. He called this innate mental structure the Language Acquisition Device (LAD). According to Chomsky, the LAD contains universal grammar—a set of grammatical rules common to all human languages.

诺姆·乔姆斯基提出，每个孩子生来就具有习得语言的生理倾向。他将这种先天的心理结构称为语言习得装置（LAD）。根据乔姆斯基的观点，LAD 包含普遍语法——一套所有人类语言共有的语法规则。

Evidence for the LAD includes children’s ability to produce novel sentences they have never heard, and the fact that the stages of language development are remarkably consistent across cultures. However, critics point out that Chomsky’s theory underestimates the importance of social interaction and listening experience, which is where other theories come into play.

支持 LAD 的证据包括儿童能够说出他们从未听过的新句子，以及语言发展阶段在不同文化中惊人地一致。然而，批评者指出乔姆斯基的理论低估了社会互动和听力经验的重要性，而这正是其他理论发挥作用的地方。

6. Bruner’s Social Interactionist Approach | 布鲁纳的社会互动理论

Jerome Bruner argued that language cannot be acquired solely through an inborn device; it requires a Language Acquisition Support System (LASS) provided by caregivers. The LASS refers to the structured interactions in which adults scaffold a child’s language development, such as through joint attention, turn-taking and child-directed speech.

杰罗姆·布鲁纳主张，语言不能仅靠先天装置习得；它需要照料者提供的语言习得支持系统（LASS）。LASS 指的是成年人通过结构化的互动来支架儿童的语言发展，比如通过共同注意、轮流发言和儿向语等方式。

Child-directed speech (formerly called ‘motherese’) features a higher pitch, exaggerated intonation and repetition. This captures the infant’s auditory attention and makes the phonemic boundaries clearer, directly linking hearing with language growth. Thus, Bruner emphasises the quality of verbal and non-verbal exchanges in the child’s social world.

儿向语（以前称为“妈妈语”）具有较高的音调、夸张的语调和重复。这能抓住婴儿的听觉注意力，使音素边界更清晰，直接将听力与语言发展联系起来。因此，布鲁纳强调儿童社交世界中言语和非言语交流的质量。

Scaffolding – temporary support that is gradually removed as the child gains competence
支架 – 随着儿童能力增长而逐渐撤除的临时支持
Joint attention – adult and child focus on the same object while the adult names it
共同注意 – 成人与儿童注视同一物体，同时成人说出其名称

7. The Critical Period for Speech and Hearing | 口语与听力的关键期

The critical period hypothesis suggests there is a biologically determined window during which language must be acquired for normal development. If a child is not exposed to spoken language in early childhood, their ability to master syntax and phonology may be permanently impaired. This is closely linked to hearing, because auditory input is the primary channel for spoken language.

关键期假说认为，存在一个生物学上决定的时间窗口，在这个时期内必须习得语言才能实现正常发展。如果儿童在幼儿期未接触口语，他们掌握句法和音系的能力可能会永久受损。这与听力密切相关，因为听觉输入是口语的主要渠道。

Classic evidence comes from case studies such as Genie, who was deprived of linguistic input until adolescence. Despite intensive therapy, she never fully acquired grammar. Other supporting evidence includes the observation that cochlear implants are more effective when fitted before the age of two, underscoring the importance of early auditory stimulation.

经典证据来自个案研究，如吉妮（Genie），她在青春期前被剥夺了语言输入。尽管接受了强化治疗，她从未完全掌握语法。其他支持性证据包括观察发现，人工耳蜗在两岁前植入效果更好，这强调了早期听觉刺激的重要性。

8. Non-Verbal Communication and Active Listening | 非语言沟通与积极倾听

WJEC specifications also address non-verbal communication, which frequently accompanies speech. Paralinguistic features such as pitch, tone and pace influence how a verbal message is interpreted. Active listening involves not only hearing the words but also observing body language, facial expressions and eye contact to grasp the full meaning.

WJEC 大纲也涉及非语言沟通，它通常伴随言语出现。副语言特征，如音高、语气和语速，影响着口头信息如何被解读。积极倾听不仅包括听见词语，还包括观察身体语言、面部表情和眼神接触，以把握完整的意思。

Ekman’s research on facial expressions and gestures shows that some forms of non-verbal communication are universal, aiding cross-cultural listening comprehension. For psychologists, active listening is a skill that can be improved by reducing distractions, summarising the speaker’s points and asking clarifying questions, techniques that are also valuable in therapeutic settings.

埃克曼对面部表情和手势的研究表明，某些形式的非语言沟通具有普遍性，有助于跨文化听力理解。对心理学家而言，积极倾听是一种可以通过减少干扰、总结说话者观点和提出澄清性问题来提升的技能，这些技巧在治疗情境中也极有价值。

9. Key Study: Eimas et al. (1971) on Phoneme Discrimination in Infants | 关键研究：Eimas 等人 (1971) 婴儿音素辨别实验

Eimas and his colleagues studied whether infants could discriminate between similar phonemes. They used a high-amplitude sucking procedure. One-month-old infants sucked on a pacifier connected to a pressure transducer while hearing a repeated phoneme, such as /ba/. Once the infants habituated and their sucking rate declined, the sound was switched to /pa/.

Eimas 及其同事研究了婴儿能否辨别相似的音素。他们使用高振幅吮吸法。一个月大的婴儿一边吮吸连接着压力传感器的安抚奶嘴，一边反复听到某个音素，如 /ba/。一旦婴儿习惯化、吮吸速率下降，声音就切换为 /pa/。

Results showed that infants increased their sucking rate significantly when the phoneme changed, suggesting they detected the difference. This supports the idea that categorical perception is innate and not dependent on extensive listening experience, a finding frequently cited in WJEC exam answers to support the nativist perspective.

结果显示，当音素改变时，婴儿的吮吸速率显著增加，表明他们察觉到了差异。这支持了范畴性知觉是先天具备的，并不依赖于大量的听力经验，这一发现常被 WJEC 考试答案引用来支持先天论观点。

10. When Speech and Hearing Go Awry: Communication Disorders | 当口语与听力出问题时：沟通障碍

Understanding speech and hearing also involves studying communication disorders. Specific language impairment (SLI) affects around 7% of children, where language development is delayed despite normal hearing and intelligence. Phonological disorders, such as difficulty producing certain phonemes, can hamper intelligibility.

理解口语与听力也涉及对沟通障碍的研究。特定型语言障碍（SLI）影响约7%的儿童，表现为尽管听力与智力正常，但语言发展迟缓。音系障碍，如生成某些音素困难，可能影响言语的可懂度。

Hearing loss, whether congenital or acquired, has profound implications. Early identification and intervention, including hearing aids and speech therapy, can significantly improve outcomes. Exam questions may ask you to discuss the psychological impact of hearing impairment on social development and self-esteem, linking back to the importance of functional hearing for normal social interaction.

听力损失，无论是先天性还是后天获得的，都有深远的影响。早期识别与干预，包括助听器和言语治疗，能显著改善结果。考题可能会要求你讨论听力障碍对社会发展和自尊的心理影响，并联系到功能性听力对于正常社交互动的重要性。

11. Applying Theories to Exam Questions on Speech and Hearing | 将理论应用于口语与听力的考题

When tackling WJEC examination questions, it is crucial to structure your answers using evidence. For a question like ‘Discuss the role of nature and nurture in the development of speech perception’, you might outline Chomsky’s LAD and Eimas et al.’s study for nature, then contrast it with Bruner’s LASS and the effects of hearing deprivation.

在应对 WJEC 考试题目时，使用证据来组织答案是至关重要的。对于像“讨论先天与后天在言语知觉发展中的作用”这样的问题，你可以为先天方面概述乔姆斯基的 LAD 和 Eimas 等人的研究，然后用布鲁纳的 LASS 和听力剥夺的影响来对比。

Examiners reward critical evaluation. Do not simply describe theories; weigh them against each other. Acknowledge that modern psychologists often favour an interactionist approach, recognising that an intact auditory system provides the platform, but rich social input is needed to activate the innate capacity for speech. Use terms such as ‘phonemes’, ‘categorical perception’ and ‘critical period’ to demonstrate subject knowledge.

考官会奖励批判性评价。不要仅仅描述理论，要相互权衡。要承认现代心理学家通常倾向于互动主义取向，即认识到完好的听觉系统提供了平台，但丰富的社会输入是激活先天言语能力所必需的。使用“音素”、“范畴性知觉”和“关键期”等术语来展示学科知识。

12. Revision Tips for the Speech and Hearing Topic | 口语与听力主题的复习建议

Create a glossary of key terms in both English and your home language. Flashcards with the terms ‘Language Acquisition Device’, ‘categorical perception’ and ‘child-directed speech’ on one side and definitions on the other are highly effective. Practise drawing and labelling a simple diagram of the auditory pathway.

用英语和你的母语制作关键术语词汇表。一面写着“语言习得装置”、“范畴性知觉”和“儿向语”等术语，另一面写着定义的闪卡非常有效。练习绘制并标注听觉通路的简图。

Form study groups where you explain theories aloud, which reinforces both your understanding of speech and your ability to articulate answers in an exam setting. Time yourself writing essay plans for past paper questions. Finally, listen to podcasts or watch videos on language development, as the auditory input will help consolidate the material in a different modality.

组建学习小组，你可以在其中大声解释理论，这既能强化你对言语的理解，也能锻炼你在考场中清晰表达答案的能力。计时为历年试卷题目撰写论文提纲。最后，收听语言发展方面的播客或观看相关视频，因为听觉输入将以不同方式帮助巩固材料。
