欢迎阅读这份9年级CCEA心理学单元测试模拟卷的详细解析。我们将逐一讲解研究方法、记忆、依恋、社会影响、大脑功能、认知发展、心理健康和数据处理等典型题目，提供标准答案和考情分析，以加深你的理解。
1. Research Methods and Ethics | 研究方法与伦理
A common multiple-choice question tests whether you can distinguish between the independent variable (IV) and the dependent variable (DV).
一道常见的选择题考查你是否能区分自变量（IV）和因变量（DV）。
In an experiment, the IV is the factor the researcher deliberately changes or manipulates, while the DV is the factor that is measured to see if it is affected by the changes in the IV.
在实验中，自变量是研究者有意改变或操纵的因素，而因变量是被测量的因素，以观察它是否受自变量变化的影响。
For example, if you are testing whether the amount of sleep affects reaction time, the amount of sleep is the IV and reaction time is the DV.
例如，如果你测试睡眠时长是否影响反应时间，那么睡眠时长是自变量，反应时间是因变量。
Short-answer questions often ask you to explain one ethical issue in psychological research. A strong answer would describe the need for informed consent: participants must be told the true aims and procedures before they agree to take part.
简答题常要求你解释心理学研究中的一个伦理问题。一个好的答案会描述知情同意的必要性：参与者在同意参与之前必须被告知真实目的和程序。
Another key ethical principle is protection from harm. Researchers must ensure participants do not suffer physical or psychological distress during or after the study.
另一个关键的伦理原则是免受伤害。研究者必须确保参与者在研究期间或之后不会遭受身体或心理上的痛苦。
When a mock paper asks 'Describe how a study could be improved ethically,' you can mention using a full debrief at the end, where all details are explained and any concerns are addressed.
当模拟卷问“描述如何从伦理上改进一项研究”时，你可以提到在研究结束时进行全面的事后说明，解释所有细节并处理任何担忧。
2. Memory Models and Processes | 记忆模型与过程
A typical fill-in-the-blank question tests your knowledge of the multi-store model. The three stores are sensory memory, short-term memory (STM), and long-term memory (LTM).
典型的填空题考查你对多储存模型的掌握。三个储存库分别是感觉记忆、短时记忆（STM）和长时记忆（LTM）。
Sensory memory holds information from the senses for up to half a second for visual stimuli, while echoic memory can last for two to three seconds.
感觉记忆对视觉刺激的保持时间最长为半秒，而回声记忆可以持续两到三秒。
ed capacity of 7±2 items and a duration of about 18 to 30 seconds unless rehearsal occurs.
短时记忆的容量有限，为7±2个组块，持续时间为18至30秒，除非进行复述。
Mock questions sometimes ask you to identify the type of encoding used by each store. STM tends to encode acoustically, whereas LTM encodes semantically – by meaning.
模拟题有时要求你识别每种储存库使用的编码类型。短时记忆倾向于声学编码，而长时记忆进行语义编码——即按意义编码。
When explaining why we forget from STM, you should refer to displacement or decay. A correct response might state: 'Information is pushed out by new incoming items because STM has limited capacity.'
在解释短时记忆为何遗忘时，你应提到干扰或衰退。正确的回答可能是：“由于短时记忆容量有限，新的信息会将旧的信息排挤出去。”
3. Attachment and Early Development | 依恋与早期发展
Questions about attachment typically refer to Ainsworth's Strange Situation. You need to describe the three main attachment types: secure, insecure-avoidant, and insecure-resistant.
关于依恋的题目通常涉及Ainsworth的陌生情境。你需要描述三种主要的依恋类型：安全型、不安全-回避型和不安全-反抗型。
Secure infants use the caregiver as a safe base, show distress when separated, and are easily soothed upon reunion. The correct answer in a multiple-choice item often highlights reunion behaviour.
安全型婴儿把照顾者当作安全基地，分离时表现出痛苦，重聚时容易被安抚。选择题中，正确答案通常强调重聚行为。
In an extended-response question, you might be asked to discuss cultural variations in attachment. A model answer notes that secure attachment is the most common pattern across cultures, but that rates of avoidant and resistant attachment differ.
在扩展回答题中，你可能会被要求讨论依恋的文化差异。标准答案指出，安全型依恋是跨文化中最常见的模式，但回避型和反抗型的比例存在差异。
Mock papers also test the concept of maternal deprivation, often referring to Bowlby's work. Key points include the critical period of the first two years and the potential long-term effects on emotional development.
模拟卷还会考查母性剥夺的概念，常提及Bowlby的研究。关键点包括最初两年的关键期以及对情感发展的潜在长期影响。
4. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Questions on conformity usually ask about Asch's line study. The independent variable was the presence of confederates giving the wrong answer, and the dependent variable was whether the real participant conformed.
关于从众的题目通常问及Asch的线段实验。自变量是同谋者给出错误答案的存在，因变量是真实参与者是否从众。
A typical short-answer query is 'Explain one factor that affects conformity.' You could describe group size: conformity increases as the group size grows up to about three or four confederates, after which it levels off.
简答题典型问题是“解释一个影响从众的因素”。你可以描述群体大小：随着群体规模增加到大约三到四个同谋者，从众程度会提高，之后趋于平稳。
Obedience items often reference Milgram's electric shock experiment. The key finding was that 65% of participants continued to the maximum shock level under an authority figure's instruction, even when the learner cried out in pain.
关于服从的题目常引用Milgram的电击实验。关键发现是，65%的参与者在权威人物的指令下，即使
