To excel in CCEA Year 7 Psychology, you need to practise questions that blend knowledge from different disciplines. This article provides ten integrated applied questions that help you build cross-curricular skills, from calculating averages to evaluating brain scans and interpreting scatter plots. Each question is followed by a bilingual explanation so that you can learn key terms and reasoning in both English and Chinese.
心理学不仅是研究心智与行为的学科，还与生物学、化学、数学、地理和伦理学等领域紧密相连。要想在 CCEA 七年级心理学中取得优异成绩，你需要练习融合不同学科知识的题目。本文提供十道跨学科综合应用题，帮助你培养跨学科技能，内容包括计算平均值、评估脑成像图、解读散点图等。每道题都附有中英双语的解析，方便你同时掌握关键词汇和推理过程。
1. Identifying Independent and Dependent Variables | 识别自变量与因变量
In psychological experiments, the independent variable (IV) is the factor that the researcher manipulates or changes, while the dependent variable (DV) is what is measured to see the effect of the IV. Consider this scenario: A psychologist wants to test if listening to music improves concentration. She asks one group of participants to complete a puzzle while listening to classical music, and another group to complete the same puzzle in silence. The number of puzzles solved correctly is recorded.
在心理学实验中，自变量（IV）是研究者操控或改变的因素，因变量（DV）则是被测量以观察自变量效应的量。考虑以下场景：一位心理学家想测试听音乐是否能提高注意力。她让一组参与者在听古典音乐的同时完成拼图，另一组在安静环境中完成相同的拼图，并记录正确解决的拼图数量。
Question: Identify the IV and DV in this study.
问题：找出本研究中的自变量和因变量。
Answer: The IV is the presence or absence of music (music vs. silence). The DV is the number of puzzles solved correctly.
答案：自变量是音乐的有无（音乐 vs. 安静），因变量是正确解决的拼图数量。
Now try another: A researcher gives one group a sugary drink and another group water, then measures their running speed. What are the IV and DV?
再试一个：一位研究者给一组含糖饮料，另一组白水，然后测量他们的跑步速度。自变量和因变量分别是什么？
Answer: IV = type of drink (sugary vs. water); DV = running speed. Being able to spot these variables is a key skill that links scientific methodology with mathematical thinking.
答案：自变量 = 饮料类型（含糖 vs. 水）；因变量 = 跑步速度。能够识别这些变量是一项连接科学方法论与数学思维的关键技能。
2. Constructing Bar Charts from Experimental Data | 根据实验数据绘制条形图
A bar chart is a simple way to display the mean scores of different conditions in an experiment. Use the data below to construct a fully labelled bar chart.
条形图是展示实验中不同条件平均分的简单方法。使用以下数据绘制一张完整标注的条形图。
| Condition | Mean Puzzles Solved |
|---|---|
| Music | 15 |
| Silence | 10 |
Steps for constructing the chart:
绘制图表的步骤：
Step 1: Draw the horizontal x-axis and write the label ‘Condition’. Mark two positions for ‘Music’ and ‘Silence’.
第一步：绘制横轴（x 轴），并写上标签“条件”。标出“音乐”和“安静”两个位置。
Step 2: Draw the vertical y-axis and label it ‘Mean Number of Puzzles Solved’. Choose a scale from 0 to 20, with an interval of 2 or 5.
第二步：绘制纵轴（y 轴），标注“平均解决的拼图数量”。选择合适的刻度，从 0 到 20，间隔可取 2 或 5。
Step 3: For the Music condition, draw a bar up to 15; for Silence, draw a bar up to 10. The bars should have equal width and be separated by a gap.
第三步：在“音乐”条件上方画一个高度到 15 的条形；在“安静”条件上方画一个高度到 10 的条形。条形宽度应相等，且条形之间留有间隙。
Step 4: Give the chart a title, such as ‘Puzzle Performance in Music and Silence’. This task integrates art, mathematics and scientific data presentation.
第四步：给图表添加标题，例如“音乐与安静环境下的拼图表现”。这项任务融合了美术、数学与科学数据的展示。
3. Calculating Mean, Median, Mode and Range | 计算平均数、中位数、众数和极差
A psychologist measured the number of words recalled by ten students in a memory test. The scores were: 9, 12, 14, 10, 15, 13, 11, 14, 12, 10. These descriptive statistics help summarise the data.
一位心理学家测量了十名学生在记忆测试中回忆的单词数量，分数分别为：9, 12, 14, 10, 15, 13, 11, 14, 12, 10。这些描述性统计量有助于概括数据的特征。
First, calculate the mean. Use the formula:
首先，计算平均数。使用以下公式：
Mean = Σx ÷ n
Σx is the sum of all scores, and n is the number of scores. Sum = 9+12+14+10+15+13+11+14+12+10 = 130. n = 10. Mean = 130 ÷ 10 = 13.
Σx 表示所有分数的总和，n 表示分数的个数。总和 = 9+12+14+10+15+13+11+14+12+10 = 130，n = 10，平均数 = 130 ÷ 10 = 13。
Second, find the median. Arrange the scores in ascending order: 9, 10, 10, 11, 12, 12, 13, 14, 14, 15. With 10 scores (an even number), the median is the mean of the 5th and 6th values: (12 + 12) ÷ 2 = 12.
其次，确定中位数。将分数从小到大排列：9, 10, 10, 11, 12, 12, 13, 14, 14, 15。因为共有 10 个分数（偶数个），中位数是第 5 和第 6 个数值的平均数：(12 + 12) ÷ 2 = 12。
Third, identify the mode. The scores 10, 12 and 14 each appear twice, so the data set is multimodal.
第三，找出众数。分数 10、12 和 14 各出现两次，因此该数据组是多众数的。
Finally, calculate the range. Range = maximum – minimum = 15 – 9 = 6. These calculations show how mathematics is used to describe psychological data.
最后，计算极差。极差 = 最大值 – 最小值 = 15 – 9 = 6。这些计算展示了如何用数学描述心理学数据。
4. Brain Structures and Their Functions | 大脑结构及其功能
Psychologists working in biological psychology need to link brain areas to behaviour. The table below shows four major lobes of the cerebral cortex and two deeper structures.
从事生物心理学的心理学家需要将大脑区域与行为联系起来。下表展示了大脑皮层的四个主要脑叶以及两个深层结构。
| Brain Structure | Main Function |
|---|---|
| Frontal lobe | Reasoning, planning, speech production |
| Parietal lobe | Touch, spatial awareness, body orientation |
| Occipital lobe | Visual processing |
| Temporal lobe | Hearing, memory, understanding language |
| Cerebellum | Balance, coordination, fine motor skills |
| Brain stem | Heartbeat, breathing, basic survival functions |
Question: After an accident, a patient reports that she cannot recognise familiar faces, yet her eyes are healthy. Which lobe is most likely damaged? Use your knowledge of localisation of function.
问题：事故发生后，一位患者报告说她无法辨认熟悉的面孔，但其眼睛是健康的。最可能受损的是哪个脑叶？请利用功能定位的知识作答。
Answer: The occipital lobe is responsible for processing visual information. Damage to this region, particularly the fusiform face area within the temporal-occipital border, can cause prosopagnosia (face blindness). This question shows how biology explains psychological phenomena.
答案：枕叶负责处理视觉信息。该区域（尤其是枕颞交界处的梭状回面孔区）受损可导致面孔失认症（脸盲）。这一问题说明了生物学如何解释心理现象。
5. Neurotransmitters and Synaptic Transmission | 神经递质与突触传递
Neurons communicate at synapses using chemical messengers called neurotransmitters. The process involves several steps that link chemistry and psychology.
神经元在突触处通过称为神经递质的化学信使进行沟通。这个过程包含多个步骤，连接了化学与心理学。
When an electrical impulse (action potential) reaches the end of a neuron, vesicles release neurotransmitters into the synaptic gap. These molecules then bind to receptor sites on the next neuron, causing a new impulse.
当电冲动（动作电位）到达神经元末梢时，囊泡将神经递质释放到突触间隙中。这些分子随后与下一个神经元上的受体位点结合，引发新冲动。
The pathway can be summarised as:
该通路可概括为：
Action potential → Vesicle release → Neurotransmitter in synapse → Receptor binding → New impulse
Key neurotransmitters include serotonin (mood, sleep) and dopamine (reward, movement). Some drugs mimic or block these chemicals: for example, selective serotonin reuptake inhibitors (SSRIs) increase serotonin availability by blocking reuptake.
重要的神经递质包括血清素（情绪、睡眠）和多巴胺（奖赏、运动）。某些药物会模拟或阻断这些化学物质：例如，选择性血清素再摄取抑制剂（SSRIs）通过阻断再摄取来提高血清素水平。
Question: If a drug blocks dopamine receptors, which psychological function would most likely be reduced?
问题：如果一种药物阻断了多巴胺受体，最可能降低的是哪项心理功能？
Answer: Motivation and feelings of reward would be reduced, because dopamine is central to the brain’s reward pathway. Linking chemical processes to mental states is a core interdisciplinary skill.
答案：动机和奖赏感会降低，因为多巴胺在大脑奖赏通路中起核心作用。将化学过程与心理状态联系起来是一项核心的跨学科技能。
6. Understanding Correlations from Scatter Plots | 解读散点图的相关性
A correlation describes a relationship between two measured variables, but it does not imply causation. The scatter plot below is described in words: as students’ anxiety scores increase from 1 to 10, their test scores tend to decrease from 90% to 40%. The points slope from top-left to bottom-right.
相关性描述的是两个被测量变量之间的关系，但并不意味着因果关系。以下用文字描述一幅散点图：随着学生的焦虑分数从 1 升高到 10，他们的考试成绩从 90% 趋向于下降到 40%。
