1. Early Brain Development and Dweck’s Mindset | 早期大脑发展与德韦克心态

The human brain undergoes rapid development both before and after birth. The brain stem, which controls basic life functions such as breathing and heart rate, is one of the first areas to mature. The thalamus acts as a relay station for sensory information, while the cerebellum coordinates movement and balance. The cerebral cortex, responsible for higher-order thinking, develops more slowly and continues to mature into early adulthood.

人类大脑在出生前后都经历快速发育。脑干是最早成熟的区域之一，控制呼吸、心跳等基本生命功能。丘脑充当感觉信息的中继站，小脑协调运动和平衡。负责高级思维的大脑皮层发育较慢，直至成年早期仍在成熟。

Carol Dweck’s mindset theory distinguishes between a fixed mindset and a growth mindset. Individuals with a fixed mindset believe intelligence is innate and unchangeable, leading them to avoid challenges. Those with a growth mindset view ability as malleable and embrace effort, resulting in greater resilience and learning. Gunderson et al. (2013) found that children praised for effort were more likely to develop a growth mindset and persevere with difficult tasks.

卡罗尔·德韦克的心态理论区分了固定心态与成长心态。具有固定心态的人认为智力是与生俱来且不可改变的，因此会回避挑战。具有成长心态的人认为能力是可塑的，乐于付出努力，从而拥有更强的韧性和学习能力。冈德森等人（2013）发现，因努力而受到表扬的儿童更可能形成成长心态，并在困难任务中坚持不懈。

2. Piaget’s Stages of Cognitive Development | 皮亚杰认知发展阶段

Jean Piaget proposed that children think differently from adults and pass through four universal stages. The sensorimotor stage (0-2 years) involves learning through senses and motor actions; object permanence develops around 8 months. In the pre-operational stage (2-7 years), children use symbols but remain egocentric, struggling to see others’ perspectives, as shown by Piaget’s three mountains task (1952). The concrete operational stage (7-11 years) brings logical thinking about tangible objects, including conservation of number and volume. Finally, the formal operational stage (11+ years) enables abstract reasoning and hypothesis testing.

让·皮亚杰提出儿童的思维方式与成人不同，并经历四个普遍的发展阶段。感觉运动阶段（0-2岁）通过感觉和动作进行学习；客体永久性在大约8个月时形成。前运算阶段（2-7岁）的儿童能使用符号，但仍以自我为中心，难以从他人视角看问题，正如皮亚杰（1952）的三山任务所示。具体运算阶段（7-11岁）带来了对具体事物的逻辑思维，包括数量和体积守恒。最后，形式运算阶段（11岁以上）具备了抽象推理和假设检验的能力。

Piaget’s work has influenced education by encouraging discovery learning and readiness. However, critics argue that he underestimated younger children’s abilities and that cognitive development may be more continuous. Nonetheless, the stages remain a cornerstone of developmental psychology and are required knowledge for the GCSE.

皮亚杰的研究通过倡导发现学习和准备度概念影响了教育。然而，批评者认为他低估了年幼儿童的能力，并且认知发展可能更具连续性。尽管如此，这些阶段仍是发展心理学的基石，也是GCSE的必考内容。

3. Memory: Multi-Store and Working Memory Models | 记忆：多存储与工作记忆模型

Atkinson and Shiffrin (1968) proposed the multi-store model of memory, which describes three separate stores. The sensory register holds information very briefly (less than half a second for visual, a few seconds for auditory). If attention is paid, information moves to short-term memory (STM). STM has a limited capacity of approximately 7±2 chunks and a duration of about 18-30 seconds without rehearsal. Rehearsal then transfers information into long-term memory (LTM), which has potentially unlimited capacity and a permanent duration.

阿特金森和希夫林（1968）提出了记忆的多存储模型，描述了三个独立的存储器。感觉登记器非常短暂地保存信息（视觉信息不足半秒，听觉信息几秒）。如果给予注意，信息进入短时记忆（STM）。STM的容量有限，约为7±2个组块，不经复述的持续时间约为18-30秒。复述可将信息转入长时记忆（LTM），其容量和持续时间在理论上都是无限的。

Baddeley and Hitch (1974) later developed the working memory model, which replaces the unitary STM. It features a central executive that directs attention and coordinates three slave systems: the phonological loop (processing sound and language), the visuospatial sketchpad (processing visual and spatial information), and the episodic buffer (integrating information from different sources and linking to LTM). This model better explains multitasking and is supported by dual-task studies.

巴德利和希奇（1974）后来提出了工作记忆模型，取代了单一的短时记忆。该模型包含一个中央执行系统，负责引导注意并协调三个从属系统：语音回路（处理声音和语言）、视觉空间画板（处理视觉和空间信息）和情景缓冲器（整合不同来源的信息并与长时记忆联系）。这个模型更好地解释了多任务现象，并得到双任务实验的支持。

4. Forgetting and Eyewitness Testimony | 遗忘与目击者证词

Forgetting can occur due to interference, whereby new or old information disrupts recall. Proactive interference happens when old memories hinder new learning; retroactive interference is when new information impairs old memories. Context-dependent forgetting also plays a role: recall is better when the external environment matches the learning context (Godden & Baddeley, 1975).

遗忘可能源于信息间的干扰，即新信息或旧信息干扰回忆。前摄干扰指旧记忆阻碍新学习；倒摄干扰指新信息损害旧记忆。情境依赖遗忘也起重要作用：当外部环境与学习情境匹配时，回忆效果更好（戈登和巴德利，1975）。

Eyewitness testimony is notoriously unreliable. Bartlett (1932) demonstrated that memory is reconstructive through the ‘War of the Ghosts’ study, where participants distorted the story to fit their own cultural schemas. Loftus and Palmer (1974) showed how leading questions can alter memory: participants who heard the verb ‘smashed’ estimated higher speeds in a car accident video than those given the word ‘contacted’. This reveals the malleability of memory and has significant implications for the legal system.

目击者证词并不可靠。巴特利特（1932）通过“幽灵之战”研究证明了记忆是重构性的，参与者会歪曲故事以符合自身的文化图式。洛夫特斯和帕尔默（1974）展示了引导性问题如何改变记忆：观看车祸视频后，听到动词“猛撞”的参与者所估计的车速远高于听到“接触”的参与者。这揭示了记忆的可塑性，对法律系统具有重要影响。

5. Unipolar Depression: Symptoms and Explanations | 单相抑郁症：症状与解释

Unipolar depression is a mood disorder characterised by persistent low mood, loss of interest or pleasure (anhedonia), fatigue, changes in appetite or sleep, feelings of worthlessness, and difficulty concentrating. For a diagnosis, symptoms must be present for at least two weeks and cause significant distress or impairment. According to the World Health Organization, depression is a leading cause of disability worldwide.

单相抑郁症是一种心境障碍，特征为持续的情绪低落、兴趣或快感丧失（快感缺失）、疲乏、食欲或睡眠改变、自我价值感低下以及注意力困难。诊断要求症状持续至少两周，并造成显著痛苦或功能损害。据世界卫生组织统计，抑郁症是全球致残的主要原因之一。

Biological explanations emphasise the role of neurotransmitters, particularly low levels of serotonin and noradrenaline. Genetic factors also contribute, as shown by twin studies. Psychological explanations include Beck’s negative triad (negative views of the self, the world, and the future) and Ellis’s ABC model, where activating events lead to irrational beliefs, producing negative emotional consequences. Both cognitive behavioural therapy (CBT) and antidepressant drugs (e.g., SSRIs) are effective treatments.

生物学解释强调神经递质的作用，特别是血清素和去甲肾上腺素水平偏低。遗传因素也有贡献，双生子研究证实了这一点。心理学解释包括贝克的负性认知三联（对自我、世界和未来的消极看法），以及埃利斯的ABC模型，即激发事件经由非理性信念导致消极情绪后果。认知行为疗法（CBT）和抗抑郁药物（如SSRIs）均为有效干预方式。

6. Addiction: Causes and Treatments | 成瘾：成因与治疗

Addiction is characterised by a strong compulsion to engage in a behaviour or take a substance despite harmful consequences. Griffiths (2005) identified six components of addiction: salience (the behaviour dominates thinking), mood modification, tolerance, withdrawal, conflict, and relapse. These apply to both substance addictions (e.g., nicotine) and behavioural addictions such as gambling.

成瘾的特征是尽管存在有害后果，个体仍被强烈驱策从事某种行为或使用某种物质。格里菲斯（2005）确定了成瘾的六个组成部分：突出性（该行为主导思维）、情绪调节、耐受性、戒断反应、冲突和复发。这些标准既适用于物质成瘾（如尼古丁），也适用于赌博等行为成瘾。

Biological explanations point to the dopamine reward pathway: addictive substances or behaviours increase dopamine levels in the nucleus accumbens, creating intense pleasure and reinforcing the habit. Genetic vulnerability and changes in the prefrontal cortex also play a part. Psychological explanations include operant conditioning, where positive reinforcement (pleasure) and negative reinforcement (relief from withdrawal) maintain the behaviour. Social factors such as peer pressure and family norms are also influential. Treatments range from biological interventions like methadone to psychological approaches such as aversion therapy and self-help groups (e.g., Alcoholics Anonymous).

生物学解释指向多巴胺奖赏通路：成瘾物质或行为会提高伏隔核的多巴胺水平，产生强烈的愉悦感并强化该习惯。遗传易感性及前额叶皮层的变化也起一定作用。心理学解释包括操作性条件反射，即正强化（愉悦感）和负强化（戒断症状缓解）共同维持行为。同伴压力和家庭规范等社会因素也很重要。治疗方法从美沙酮等生物学干预到厌恶疗法和自助小组（如戒酒匿名会）等多种多样。

7. The Brain and Neuropsychology | 大脑与神经心理学

A neuron consists of a cell body, dendrites (receiving signals), an axon (carrying impulses away), and terminal buttons that release neurotransmitters across the synapse. The myelin sheath insulates the axon and speeds up transmission. Communication between neurons is electrochemical: an electrical impulse triggers the release of neurotransmitters, which bind to receptor sites on the postsynaptic neuron, potentially causing excitation or inhibition.

神经元由细胞体、树突（接收信号）、轴突（传导冲动）及终扣组成，终扣在突触处释放神经递质。髓鞘包裹轴突起绝缘作用并加快传导速度。神经元间的通信是电化学性的：电冲动触发神经递质释放，递质与突触后神经元上的受体结合，可能引发兴奋或抑制。

The cerebral cortex is divided into four lobes: the frontal lobe (decision-making, personality, motor control), the parietal lobe (sensory processing, spatial awareness), the temporal lobe (auditory processing and memory), and the occipital lobe (vision). The cerebellum supports coordination, while the brain stem handles vital functions. Sperry (1968) studied split-brain patients whose corpus callosum had been cut. He found that the left hemisphere specialises in language and analytical tasks, whereas the right hemisphere excels in spatial and creative tasks, demonstrating hemispheric lateralisation.

大脑皮层分为四个叶：额叶（决策、人格、运动控制）、顶叶（感觉处理、空间意识）、颞叶（听觉处理和记忆）及枕叶（视觉）。小脑辅助协调，脑干掌管生命功能。斯佩里（1968）研究了胼胝体被切断的裂脑患者，发现左半球专门负责语言和分析性任务，右半球擅长空间和创造性任务，证明了大脑功能的偏侧化。

8. Social Influence: Conformity, Obedience, and Prosocial Behaviour | 社会影响：从众、服从与亲社会行为

Conformity refers to yielding to group pressure. Asch (1951) demonstrated that participants would give clearly incorrect answers about line lengths to conform with a unanimous majority. Conformity increased with larger group sizes up to three confederates, and decreased when there was a dissenting partner. Obedience involves following direct orders from an authority figure. Milgram (1963) found that 65% of participants administered what they believed were lethal electric shocks to a learner, simply because an experimenter instructed them to continue.

从众指屈从于群体压力。阿希（1951）证明，参与者会为了与一致多数保持一致而给出明显错误的线段长度判断。当合谋者人数增至三人时，从众程度上升；若有异议同伴加入则下降。服从涉及遵循权威人物的直接指令。米尔格拉姆（1963）发现，65%的参与者仅仅因为实验者要求继续，就对学习者施加了他们认为是致命的电击。

Bystander intervention is influenced by diffusion of responsibility. Latané and Darley (1968) showed that in an emergency, the presence of other bystanders reduces the likelihood of any one person helping. Deindividuation, as shown in Zimbardo’s Stanford prison experiment (1973), illustrates how anonymity and group immersion can lead to a loss of personal identity and an increase in aggressive behaviour. Prejudice was studied in Sherif’s Robbers Cave experiment (1961), where competition between groups led to hostility, but superordinate goals successfully reduced conflict.

旁观者干预受责任扩散的影响。拉塔内和达利（1968）表明，紧急情境中其他旁观者的出现会降低任何个体提供帮助的可能性。去个体化，如津巴多的斯坦福监狱实验（1973）所示，揭示了匿名状态和群体浸入如何导致个人身份感丧失并加剧攻击行为。谢里夫的强盗洞实验（1961）研究了偏见，组间竞争引发了敌意，但超然目标成功减少了冲突。

9. Research Methods and Ethical Considerations | 研究方法与伦理考量

Psychologists use a variety of research methods. Experiments involve manipulating an independent variable (IV) to measure its effect on a dependent variable (DV), while controlling extraneous variables. Experimental designs include independent groups, repeated measures, and matched pairs. Correlational studies examine relationships without manipulation, with the correlation coefficient ‘r’ ranging from -1.0 to +1.0. Observations, interviews, and questionnaires allow data collection in natural or structured settings.

心理学家使用多种研究方法。实验通过操纵自变量（IV）来测量其对因变量（DV）的影响，并控制额外变量。实验设计包括独立组设计、重复测量设计和配对设计。相关研究在不进行操纵的情况下考察变量间关系，相关系数“r”取值范围为-1.0到+1.0。观察法、访谈法和问卷法可在自然或结构化环境中收集数据。

Data analysis involves descriptive statistics such as mean, median, mode, and range. The mean is calculated as the sum of all scores divided by the number of scores:

Mean = Σ x / n

数据分析涉及描述性统计，如平均数、中位数、众数和全距。平均数的计算方式为所有分数之和除以分数的个数：

平均数 = Σ x / n

Ethical guidelines from the British Psychological Society require informed consent, protection from harm, confidentiality, and the right to withdraw. Studies with deception must be followed by a full debrief. Sampling techniques vary: random, stratified, volunteer, and opportunity sampling each have strengths and limitations regarding representativeness and bias. Understanding these principles is vital for evaluating research quality in the exam.

英国心理学会的伦理准则要求知情同意、免受伤害、保密和退出权。存在欺骗的研究之后必须进行充分的事后解说。抽样技术多样：随机抽样、分层抽样、志愿者抽样和机会抽样在代表性和偏差方面各有优缺点。理解这些原则对于在考试中评价研究质量至关重要。
