本研究探讨知觉专业知识如何促进编码和识别。在研究中记录了汽车专家和汽车新手的脑电图，以及汽车和鸟类刺激的记忆/知道任务的测试阶段。汽车专业知识影响汽车的性能和事件相关电位（ERP），但不影响鸟类。专家识别和“回忆”汽车更准确，而新手误报更多。ERPs为专家记忆的理论假设提供了神经学证据。在研究阶段的记忆编码是不那么费力，更详细的专家比新手，表明较低的平均振幅随后“回忆”汽车和难以区分的差异，由于记忆的回忆和熟悉。顶叶的新/旧效应，在识别测试中测量的回忆的相关性，只发现了专家。结果表明，精细的知觉和语义加工，知觉专业知识的特点，促进记忆编码和再认记忆。
This study examined how perceptual expertise facilitates encoding and recognition. The electroencephalogram of car experts and car novices was recorded in the study as well as test phases of a remember/know task with car and bird stimuli. Car expertise influenced performance and event-related potentials (ERPs) for cars but not birds. Experts recognized and "recollected" cars more accurately, while novices had more false alarms. The ERPs provided neural evidence for theoretical assumptions about expert memory. Memory encoding in the study phase was less effortful and more elaborate for experts than novices, as indicated by lower mean amplitudes for subsequently "recollected" cars and by indistinguishable differences due to memory for recollection and familiarity. The parietal old/new effect, a correlate of recollection measured during recognition testing, was only found for experts. The results show that refined perceptual and semantic processing, characteristics of perceptual expertise, facilitate both memory encoding and recognition memory.
