棉花糖实验的预测力在后续研究中发生了什么变化？
What happened to the predictive power of the marshmallow test in later research?
米歇尔的原始研究发现，能为更大奖励延迟满足的幼儿在若干年后学业与社会适应表现更好，这被广泛解读为自控力决定人生成就。后来一项样本量大得多、并控制家庭社会经济地位与母亲教育水平的重复研究发现，延迟时间与青少年期学业成绩的相关虽仍存在，但幅度大约减半，且在纳入背景变量后大部分预测力被吸收。这提示等待能力部分是资源稳定与信任环境的产物，把它单纯归结为个体意志品质会掩盖结构性因素。
Mischel's original work found that preschoolers who could delay gratification for a larger reward showed better academic and social outcomes years later, widely read as self-control determining life success. A much larger replication that controlled for family socioeconomic status and maternal education found the association between delay time and adolescent achievement still present but roughly half as large, with much of the predictive power absorbed once background variables entered the model. Waiting ability is therefore partly a product of stable resources and a trustworthy environment, and reducing it to individual willpower obscures structural factors.

罗马尼亚孤儿院研究揭示了早期剥夺的哪些长期后果？
What long-term consequences of early deprivation did the Romanian orphanage studies reveal?
英国的罗马尼亚收养研究追踪了从极端剥夺环境被跨国收养的儿童，发现六个月前离开机构的儿童发展基本追平对照组，而六个月后才离开的儿童在青少年与成年期仍有较高比例出现注意缺陷、类似自闭的社会性异常与认知损伤。布加勒斯特早期干预项目采用随机分配设计，把机构养育儿童安置到寄养家庭，结果显示越早安置，智商、语言与依恋安全性的改善越明显。两项研究共同支持敏感期概念，也表明干预时机比干预强度更关键。
The English and Romanian Adoptees study followed children adopted internationally out of extreme deprivation and found those who left institutions before six months of age largely caught up with comparison groups, while those who left later showed elevated rates of inattention, quasi-autistic social difficulties, and cognitive impairment persisting into adolescence and adulthood. The Bucharest Early Intervention Project used random assignment to move institutionalised children into foster care and found that earlier placement produced larger gains in IQ, language, and attachment security. Together they support the notion of sensitive periods and indicate that the timing of intervention matters more than its intensity.

错误信念任务测的是什么？为什么改用非言语版本会得出不同结论？
What do false-belief tasks measure, and why do nonverbal versions yield different conclusions?
经典的萨莉与安妮任务要求儿童预测一个不知道物品被移动的人会去哪里寻找，通过它意味着儿童理解他人可以持有与现实不符的信念，通常在四岁左右达成。但用注视时间或期待性眼动作为指标的非言语范式显示，十五个月甚至更小的婴儿在他人信念被违背时表现出惊讶反应。争论焦点在于早期反应是否已构成真正的心理理论，还是仅反映对行为规律的统计学习，因此当前研究更强调区分内隐的行为预期与需要语言与执行功能支持的外显推理。
The classic Sally-Anne task asks a child to predict where someone who did not see an object moved will look for it, and passing implies understanding that others can hold beliefs contrary to reality, typically achieved around age four. Nonverbal paradigms using looking time or anticipatory eye movements, however, show that infants as young as fifteen months react with surprise when another agent's belief is violated. The dispute is whether such early responses constitute genuine theory of mind or merely statistical learning about behavioural regularities, so current research distinguishes implicit behavioural expectations from explicit reasoning that depends on language and executive function.

皮亚杰的守恒任务为什么被批评低估了幼儿的能力？
Why is Piaget's conservation task criticised for underestimating young children?
在经典的数量守恒任务中，实验者把一排纽扣拉长后再次提问，学龄前儿童常改口说变多了，皮亚杰据此认为前运算阶段的儿童缺乏守恒概念。批评者指出，任务的语言与语用设置容易误导：连续两次问同一个问题暗示答案应当改变，而实验者刻意的操作也被儿童理解为提示。麦加里格与唐纳森把变化改为顽皮泰迪熊的破坏行为，使操作显得偶然，儿童的正确率显著上升，说明部分失败源于对成人意图的解读而非逻辑能力缺失。
In the classic number conservation task the experimenter spreads out a row of counters and repeats the question, and preschoolers often switch to saying there are now more, which Piaget took as evidence that preoperational children lack conservation. Critics observed that the task's language and pragmatics mislead: asking the same question twice implies the answer should change, and the adult's deliberate rearrangement is read as a hint. When McGarrigle and Donaldson attributed the change to a naughty teddy bear so that it looked accidental, children's accuracy rose markedly, showing part of the failure stems from interpreting adult intentions rather than from missing logic.

弗林效应指什么？近年部分国家出现的智商测分下降说明了什么？
What is the Flynn effect, and what does the recent decline in test scores in some countries suggest?
弗林通过比较各国智力测验的常模发现，二十世纪中大多数工业化国家的原始得分每十年上升约三点，增幅在瑞文推理等流体智力测验上最明显，因此需要不断重新标定常模。通常的解释包括营养与健康改善、受教育年限延长、家庭规模缩小以及日常环境中抽象符号任务增多。挪威等国基于全体征兵样本的研究显示，出生于二十世纪七十年代中期以后的世代得分转为缓慢下降，且家庭内部也出现同样趋势，这更支持环境变化而非人口构成变化的解释。
By comparing test norms across countries, Flynn found raw scores in most industrialised nations rose about three points per decade during the twentieth century, most steeply on fluid reasoning measures such as Raven's matrices, which is why norms must be restandardised repeatedly. Common explanations include better nutrition and health, longer schooling, smaller families, and a daily environment richer in abstract symbolic tasks. Studies using complete Norwegian conscription records show scores turning slowly downward for cohorts born after the mid-1970s, with the same trend appearing within families, which favours environmental change over shifts in population composition.

陌生情境实验如何划分依恋类型？这些类型的稳定性有多高？
How does the Strange Situation classify attachment styles, and how stable are those classifications?
安斯沃思设计的标准程序让一岁左右的婴儿在实验室经历母亲离开与返回，观察重点是重聚时的行为而非分离时的哭闹程度。安全型婴儿会主动寻求安抚并较快恢复探索，回避型表现出对母亲的忽视，矛盾型难以被安抚并交替出现依附与反抗，后来又补充了行为混乱的混乱型。跨文化研究发现三类比例存在系统差异，例如日本样本矛盾型偏多、德国样本回避型偏多，且分类会随家庭压力和照护变化而改变，说明它反映的是关系模式而不是婴儿固有的人格特质。
Ainsworth's standardised procedure exposes infants around one year old to a mother's departures and returns in the laboratory, with classification hinging on reunion behaviour rather than how much the baby cried during separation. Secure infants seek comfort and resume exploring fairly quickly, avoidant infants appear to ignore the caregiver, resistant infants are hard to soothe and alternate clinging with anger, and a disorganised category was later added for contradictory behaviour. Cross-cultural work finds systematic differences in the distribution — more resistant classifications in Japanese samples, more avoidant in German ones — and classifications shift with family stress and changes in care, indicating a relationship pattern rather than a fixed infant trait.
