本研究采用事件相关脑电位（ERP）和反应时（RTs）研究听觉中内源性内隐空间定向的机制。在一个实验条件下，受试者被指示对任何目标音调做出反应，无论它是否存在于有效（空间预测线索），中性（无信息线索）或无效（误导线索）试验中。在另一个实验条件下，只有在提示位置出现的目标音调需要反应，也就是说，受试者可以完全忽略在未提示耳朵出现的音调。提示有效性对RT有影响，包括有效试验的收益和无效试验相对于中立试验的RT的成本。在100 - 300毫秒的时间范围内，提示有效性也有明显的ERP效应。在未提示音可以忽略的条件下，这些ERP效应被放大。提示效度对反应时和事件相关电位的影响表现出隐蔽定向在听觉刺激需要一个公开的反应，也不需要一个行为反应的刺激。有人认为，这种注意选择位于信息处理的中间阶段，而不是在外围阶段，如基本的感官特定的处理或反应选择。
The present study examines mechanisms of endogenous covert spatial orienting in audition as revealed by event-related brain potentials (ERPs) and reaction times (RTs). In one experimental condition, subjects were instructed to respond to any target tone irrespective of whether it was presented in a valid (spatially predictive cue), neutral (uninformative cue), or invalid (misleading cue) trial. In another experimental condition, only target tones presented at a cued position required a response—that is, subjects could completely ignore tones presented at the uncued ear. Cue validity had an effect on RT, which consisted in benefits for valid trials and in costs for invalid trials relative to the RTs in neutral trials. There were also distinct ERP effects of cue validity in the 100–300 msec time range. These ERP effects were enlarged in the condition in which uncued tones could be ignored. The effects of cue validity on RTs and ERPs demonstrated covert orienting in audition both for stimuli requiring an overt response and also for stimuli that did not require a behavioural response. It is argued that this attentional selection is located at intermediate stages of information processing, rather than at peripheral stages such as basic sensory-specific processing or response selection.
