1Ambady suspected that deliberation focused them on vivid but misleading cues, such as certain gestures or utterances, rather than letting the complex interplay of subtle signals form a holistic impression.
主干主语：Ambady；谓语：suspected；宾语：that 引导的宾语从句（从句主干：deliberation focused them on cues... rather than letting...）
结构主句后接 that 引导的宾语从句。从句内部由 rather than 连接两个并列结构：focused them on vivid but misleading cues 与 letting the complex interplay...form a holistic impression，前者是实际发生的情况，后者是被否定的替代做法。such as 引出插入性举例，let 后接省略 to 的不定式 form 作宾语补足语，interplay of subtle signals 意为"细微信号之间复杂的相互作用"。
译文Ambady 怀疑，深思熟虑让参与者把注意力集中在生动却具有误导性的线索上，比如某些手势或话语，而不是让那些细微信号之间复杂的相互作用自然形成一个整体印象。
考点rather than 连接并列谓语结构，表"而不是"，常考肯否对比 · let sb./sth. do sth. 中不定式省略 to，form 在此作宾语补足语而非谓语
2And people made car-buying decisions that were both objectively better and more personally satisfying when asked to focus on their feelings rather than on details, but only if the decision was complex—when they had a lot of information to process.
主干主语：people；谓语：made；宾语：car-buying decisions（后接定语从句 that were both...satisfying）
结构decisions 后接 that 引导的定语从句，从句中 both...and... 连接两个比较级表语。when asked to focus... 是省略了主语和 be 动词的时间状语从句（= when they were asked），rather than 表对比。but only if 引出限制性条件状语从句，破折号后的 when 从句是对 complex 这一条件的同位语式解释，说明复杂具体指什么。
译文而且，当人们被要求关注自己的感受而非细节时，他们做出的购车决定客观上更优、个人满意度也更高——但前提是决定足够复杂，也就是有大量信息需要处理的时候。
考点when asked to... 为状语从句的省略形式，补充完整为 when they were asked to... · only if 引导条件状语从句表"只有当……才"，破折号后的 when 从句起补充解释作用，不是新的时间状语
3In one study, participants completed a battery of eight tasks, including four that tapped reflective thinking (discerning rules, comprehending vocabulary) and four that tapped intuition and creativity (generating new products or figures of speech).
主干主语：participants；谓语：completed；宾语：a battery of eight tasks
结构句子主干简单，难点在宾语后的修饰成分：including... 是现在分词短语作后置定语，其中包含两个并列的 four，各带一个 that 引导的定语从句（that tapped reflective thinking / that tapped intuition and creativity），两个括号内的动名词短语分别作同位语，举例说明两类任务的具体内容。a battery of 意为"一系列、一整套"。
译文在一项研究中，参与者完成了八项任务，其中四项考查反思性思维（辨别规则、理解词汇），另外四项考查直觉与创造力（创造新产品或新修辞手法）。
考点including 分词短语内嵌两个并列的定语从句 that tapped...，注意 tapped 在此意为"激发、动用" · 括号内动名词短语作同位语举例，阅读时可先略读，避免打断主干理解
4Then they rated the degree to which they had used intuition ("gut feelings," "hunches," "my heart").
主干主语：they；谓语：rated；宾语：the degree（后接"介词 + which"定语从句 to which they had used intuition）
结构核心考点是"介词 to + which"引导的定语从句，修饰 the degree，还原为 they had used intuition to the degree（他们在多大程度上使用了直觉），to 与 degree 构成固定搭配，故前置到 which 之前。括号内三个名词短语是 intuition 的同位语，用口语化表达解释"直觉"的含义。
译文然后，他们评估了自己在多大程度上动用了直觉（"本能感觉""预感""内心的声音"）。
考点"介词 + which"引导定语从句：to which = to the degree，判断介词要看从句内部的固定搭配 · to the degree/extent that... 是高频结构，表示"在……程度上"，注意识别其变体
