我们能否在无法描述目标的情况下，建立关于目标发生地点的内生预期？受试者在不被告知有效和无效试验比例的情况下，进行了不同比例的线索-目标检测任务，并表现出典型的内源性效应。大约一半的人随后能够正确地描述线索-目标关系（“言语化者”）。然而，即使是nonverbalizer参与者表现出内源性定向与周边线索（实验1和3），而不仅仅取决于实践（实验2）。明确的指令并没有带来显着的优势，在性能（实验4）。与中央象征性线索，只有言语表现出可靠的内源性影响（实验5）。我们的结论是，内源性定向与周边线索可以独立于参与者发展明确的假设线索-目标关系。(c)2006年由Elsevier Inc.出版
Can we build endogenous expectations about the locus of occurrence of a target without being able to describe them? Participants performed cue-target detection tasks with different proportions of valid and invalid trials, without being informed of these proportions, and demonstrated typical endogenous effects. About half were subsequently able to correctly describe the cue-target relationships ('verbalizers'). However, even non-verbalizer participants showed endogenous orienting with peripheral cues (Experiments 1 and 3), not depending solely on practice (Experiment 2). Explicit instructions did not bring about dramatic advantages in performance (Experiment 4). With central symbolic cues, only verbalizers showed reliable endogenous effects (Experiment 5). We concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue-target relationships.
