言语错误揭示了说话人对音位制约的内隐知识，既有语言范围的制约(例如，当一个人说英语时，/ŋ/不能是音节的开头)，也有实验诱导的制约(例如，/k/不能是实验过程中的开头)。四个实验考察了新的二阶限制条件的获得，其中辅音的允许位置取决于音节的其他属性(例如，/k/只有在元音为/i/时才能是声母)。在为期4天的实验中，参与者背诵了一串串显示出新奇限制的音节。他们的错误反映了新学到的限制，但直到培训的第二天才出现。这与之前的研究不同，以前的研究表明，误差几乎立即对一阶约束变得敏感。提出了一种学习将音素分配到音节位置的模型。它将二阶约束习得的相对缓慢归因于这些约束的自我干扰特性。
Speech errors reveal the speaker's implicit knowledge of phonotactic constraints, both languagewide constraints (eg,/ŋ/cannot be a syllable onset when one is speaking English) and experimentally induced constraints (eg,/k/cannot be an onset during the experiment). Four experiments investigated the acquisition of novel 2nd-order constraints, in which the allowable position of a consonant depends on some other property of the syllable (eg,/k/can only be an onset if the vowel is/I/). Participants recited strings of syllables that exhibited the novel constraints throughout a 4-day experiment. Their errors reflected the newly learned constraints but not until the 2nd day of training. This contrasts with previous research showing that errors become sensitive to 1st-order constraints almost immediately. A model that learns to assign phonemes to syllable positions is presented. It attributes the relative slowness of the acquisition of 2nd-order constraints to the self-interfering property of these constraints.
