什么是智力里的“g 因素”（一般智力）？
What is the 'g factor' (general intelligence)?
不同认知测验成绩彼此正相关，统计上可提取出一个共同因子 g，解释各测验的共享方差。支持者认为 g 反映神经效率等通用资源，批评者则强调具体能力与文化偏差，争论仍在继续。
Different cognitive tests correlate positively; statistically a common factor g explains their shared variance. Supporters link g to general resources like neural efficiency, while critics stress specific abilities and cultural bias—the debate continues.

Spearman 的“一般智力因素 g”是什么意思？
What is Spearman's general intelligence factor “g”?
Spearman 于 1904 年通过因素分析发现，各种心智测验成绩之间存在正相关，可用一个潜在的“一般智力因素 g”来解释，同时各测验还有各自的特殊因素 s。g 因素至今仍是智力研究中最被广泛支持的结构之一。
Through factor analysis in 1904, Spearman found positive correlations among diverse mental tests, explained by a latent “general intelligence factor g” plus specific factors s for each test. The g factor remains one of the most widely supported structures in intelligence research.

什么是“弗林效应（Flynn effect）”？
What is the “Flynn effect”?
弗林效应指 20 世纪多国人群在标准化 IQ 测验上的得分平均每十年上升数分的现象，由 James Flynn 于 1984 年系统报告。学界将其归因于营养、教育、环境复杂化等因素，近年在部分国家又出现得分回落的“反弗林效应”。
The Flynn effect is the widespread rise of about several IQ points per decade on standardized tests during the 20th century, systematically reported by James Flynn in 1984. Attributed to nutrition, education, and environmental complexity, some countries now show a reversing “anti-Flynn” trend.

什么是“默许偏差”与“社会赞许性”反应风格？
What are acquiescence bias and social-desirability response styles?
默许偏差指不论内容都倾向答“同意”；社会赞许性是把自己描得比真实更符合社会期待。这些反应风格会污染跨文化或自我评价数据，需在问卷设计中用反向题和效度量表控制。
Acquiescence bias is the tendency to agree regardless of content; social desirability is portraying oneself better than reality. These response styles contaminate cross-cultural or self-report data and must be controlled with reversed items and validity scales in design.

心理测量中的“项目反应理论”（IRT）是什么？
What is item response theory (IRT) in psychometrics?
IRT 用模型描述题目难度、区分度与答题者能力的关系，使不同试卷的分数可公平比较（量表等值）。它取代了古典真分数理论，是现代大型测验（如 PISA）的底层方法。
IRT models the relationship between item difficulty, discrimination and person ability, letting scores from different test forms be compared fairly (equating). It supersedes classical test theory and underlies modern large-scale assessments like PISA.

坎贝尔与菲斯克的多质多法矩阵凭什么区分聚合效度与区分效度?为什么“同一特质换方法测相关高、不同特质共用一法测相关低”才是理想格局?
How does Campbell and Fiske's multitrait-multimethod matrix separate convergent from discriminant validity, and why is it ideal when the same trait measured by different methods correlates highly while different traits sharing a method correlate poorly?
该矩阵把若干特质与若干方法的两两相关排成一张表:若同一特质跨方法的相关明显高于其余单元格,说明工具捕捉到的是特质本身而非方法伪影,这构成聚合效度的证据。反过来,若恰好共用同一测量方法的不同特质之间相关同样很高,则提示分数被共同方法变异污染,构念边界已经失效。理想模式要求“异法同质”相关压过“同法异质”相关,从而同时立起聚合与区分两条证据线。
The matrix arranges pairwise correlations among several traits and several methods: when same-trait cross-method correlations clearly exceed the remaining cells, the instrument is capturing the trait rather than method artifact, which constitutes convergent evidence. Conversely, if different traits that merely share one measuring method correlate just as strongly, scores are contaminated by common method variance and construct boundaries collapse. The ideal pattern requires heteromethod-monotrait correlations to dominate monomethod-heterotrait ones, erecting both lines of evidence at once.

智商（IQ）测验到底测的是什么？
What exactly does an IQ test measure?
IQ 主要测推理、工作记忆、处理速度和语言等通用认知能力，对学业与部分工作表现有中等预测力。它并不涵盖创造力、情商或实践智慧，且深受教育与文化环境影响。
IQ chiefly measures reasoning, working memory, processing speed and verbal ability—general cognitive skill with modest prediction of school and some job performance. It does not capture creativity, emotional skill or practical wisdom, and is shaped by education and culture.

心理测验里的“常模”是什么？
What is a 'norm' in psychological testing?
常模是某一代表性群体的分数分布，用来解释个人分数是高还是低。脱离常模，单个原始分没有意义；好的常模需与受测者同文化、同年龄层才有参考价值。
A norm is the score distribution of a representative reference group, used to interpret whether a person's score is high or low. Without norms a raw score means little; good norms must match the test-taker's culture and age to be useful.

为什么自评问卷常常不那么可靠？
Why are self-report questionnaires often unreliable?
自评受记忆偏差、社会赞许、当下情绪与对题目的理解差异影响，同一人不同天可能给出不同答案。因此重要结论常以行为任务或多方法交叉验证，而非单靠自我报告。
Self-reports suffer from memory bias, social desirability, current mood and differing interpretations, so the same person may answer differently on another day. Important conclusions often combine behavioral tasks or multiple methods rather than relying on one survey.

心理测量中“信度”与“效度”有何区别？
What is the difference between "reliability" and "validity" in psychometrics?
信度指测量结果的一致性与稳定性（如重测信度、内部一致性），效度指测量是否真的测到了它声称要测的构念（如效标关联效度、结构效度）。一句常说的话是“效度以信度为前提，但高信度不等于高效度”。
Reliability is the consistency and stability of a measure (e.g., test–retest, internal consistency), while validity is whether it truly measures the construct it claims (e.g., criterion-related, construct validity). A common saying is that validity presupposes reliability, but high reliability does not guarantee validity.

韦克斯勒智力量表（WAIS/WISC）有何特点？IQ 分数如何分布？
What are the features of the Wechsler scales (WAIS/WISC), and how are IQ scores distributed?
韦克斯勒于 1939 年编制的量表分言语与操作多个分测验，给出总智商及分量表指数，适用成人与儿童（WAIS、WISC）。现代 IQ 测验按正态分布标定，均值 100、标准差 15，约 95% 的人落在 70–130 区间。
Wechsler's scales from 1939 include multiple verbal and performance subtests yielding a full-scale IQ and index scores for adults (WAIS) and children (WISC). Modern IQ is normed to a normal distribution with mean 100 and SD 15, so about 95% score between 70 and 130.

一项信度很高却效度很低的测验,其测量结果会呈现出什么样子?能否举例说明?
What would the results of a test look like if it were highly reliable but poorly valid, and can you illustrate with an example?
此时分数极其稳定,却始终稳定地偏离了测量目标:就像一台体重秤每次给出相同读数,读数却一直错。例如以鞋码预测数学能力,重测一致性可以做得很高,与真实数学成绩的相关却接近零。可见信度只是效度的必要条件,绝非充分条件。
Scores would be extremely stable while steadily missing the intended target, like a bathroom scale that returns identical readings every time yet never lands on the true weight. Predicting mathematical ability from shoe size, for instance, could yield excellent test–retest consistency while correlating with actual performance at nearly zero. Reliability is thus a necessary condition for validity, never a sufficient one.

星座式的人格描述为什么人人觉得准?福勒实验一句话戳破的幻觉叫什么?
Why does horoscope-style personality text feel accurate to nearly everyone? One classroom experiment named the illusion.
1948年福勒给全班发了同一份人格分析——摘自星座读物的套话,如「你外表自律实则内心时有不安」「你有大量尚未发挥的潜能」——请学生按0到5评准确性,平均4.26,学生惊呼这就是自己。以放之四海皆准的模糊陈述换取高认同,就是巴纳姆效应(福勒效应)。它是MBTI、星座运势、冷读术的心理引擎:人们优先记住符合的部分、自动脑补事例,描述者永远立于不败。对策是盲测:不给标签只给基线,看预测能否胜过随机。
In 1948 Forer handed every student the same personality sketch assembled from horoscope boilerplate — disciplined outside, occasionally insecure within, unused potential — and asked them to rate its accuracy on a zero-to-five scale: average 4.26, many stunned by how personal it felt. Accepting vague, universally applicable statements as uniquely self-descriptive is the Barnum (Forer) effect — the psychological engine of astrology, MBTI-style reports and cold reading: we remember hits, auto-generate confirming examples, and the describer can never lose. The antidote is blind testing — strip labels, give baselines, and check whether predictions beat chance.
