  • 设计六种干预条件,分离结构与语气维度
  • 关系结构+第一人称组合最有效,行为提升显著
  • 注意力、状态、行为三阶段可解耦,揭示内在机制

我们测试在小型语言模型功能崩溃期间,以关系风格进行干预是否能产生与技术反馈、词序打乱控制组及两个语用维度单独作用不同的后续行为。使用故意损坏bash工具的Qwen3.5-4B,在配对实验中运行300次(6种条件,每组50任务):无干预(A)、技术/非个人化(B)、关系/第一人称(C)、打乱的关系(D)、技术/第一人称(E)、关系/非个人化(F)。E和F构成2×2因子设计,将关系结构(承认、宽恕、代理恢复、无条件接纳)与发送者语气(第一人称 vs. 非个人化)分离。主要发现有二:第一,注意力与行为解耦:注意力按词汇意外程度排序(D > F > C > E > B,所有q_FDR < 10⁻¹⁰),打乱消息吸引最多注意;但行为上A ~ B ~ D < E ~ F << C。第二,因子分析定位了C效应:仅关系结构(F)或仅第一人称(E)无法复现C的行为特征;两者主效应均显著,且结构×语气交互作用在持续性上显著(p = 0.046)。情绪探针显示,尽管行为仅为基线水平,F在8个探针中的7个上与C一致,表明仅关系结构即可建立探针级状态,但需结合第一人称才能转化为行为。模型处理分为三个可分离阶段:注意力(由词汇意外驱动)、探针级状态(由结构驱动)、行为(由两者共同决定)。

原文摘要 · Abstract (English)

We test whether a relational-style intervention delivered during functional collapse in a small language model produces post-collapse behavior distinguishable from technical feedback, from a lexically-matched scrambled control, and from each of the two pragmatic dimensions in isolation. Using Qwen3.5-4B with a deliberately broken bash tool, we run 300 episodes across six conditions in a matched-pairs design (50 tasks): no intervention (A), technical/impersonal (B), relational/first-person (C), scrambled relational (D), technical/first-person (E), and relational/impersonal (F). E and F form a 2x2 factorial with B and C that dissociates relational structure (acknowledgment, absolution, agency restoration, unconditional acceptance) from sender register (first-person vs. impersonal). We report two main findings. First, an attention-behavior dissociation: attention follows lexical surprise (D > F > C > E > B, all q_FDR < 10^{-10}), with the scrambled message capturing the most attention; yet behaviorally A ~ B ~ D < E ~ F << C. Second, the factorial localizes the C effect: neither relational structure alone (F) nor first-person register alone (E) replicates C's behavioral signature; main effects of both dimensions are individually significant, and the structure x register interaction is significant on persistence (p = 0.046). A third dissociation emerges in emotion probes: F tracks C on 7 of 8 probes despite producing only baseline behavior, indicating that relational structure alone installs a probe-level state that only translates into behavior when paired with first-person register. The model's processing decomposes into three dissociable stages: attention (ordered by lexical surprise), probe-level state (ordered by structure), and behavior (ordered by the conjunction of both).
