Perceptual salience improves the encoding of information into visual working memory (WM). However, the factors that contribute to this facilitation effect are not well understood. This study tested the influence of target familiarity on WM encoding. In each trial, participants were presented with either one or three targets and asked to encode their locations into WM. In Experiment 1, target familiarity was manipulated by presenting either an upright (familiar target) or upside-down (unfamiliarovel target) A. Increasing the novelty of the targets led to improved performance in the spatial WM task. Experiment 2 showed that participants were faster in responding to novel versus familiar targets in a spatial detection task. Experiment 3 demonstrated that the beneficial effect of target novelty on WM encoding was not driven by differences in low-level features. Our results suggest that target novelty enhances the processes required for WM encoding, just as it facilitates perceptual processing.View full textDownload full textKeywordsAttention, Encoding, Novelty, Salience, Spatial working memoryRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; var addthis_config = {"data_track_addressbar":true,"ui_click":true}; Add to shortlist Link Permalink http://dx.doi.org/10.1080/13506285.2011.594459

机译：感知显着性提高了信息到视觉工作记忆（WM）中的编码。但是，促成这种促进作用的因素尚不十分清楚。这项研究测试了目标熟悉度对WM编码的影响。在每个试验中，向参与者展示一个或三个目标，并要求将其位置编码为WM。在实验1中，通过呈现直立（熟悉的目标）或倒立（陌生/新颖的目标）A来操纵目标熟悉度。增加目标的新颖性可以改善空间WM任务的性能。实验2表明，在空间检测任务中，参与者对新颖目标和熟悉目标的反应速度更快。实验3证明，目标新颖性对WM编码的有益影响不是由低级功能的差异驱动的。我们的结果表明，目标新颖性会增强WM编码所需的过程，就像它促进感知处理一样。查看全文下载全文关键字注意，编码，新颖性，显着性，空间工作内存：：“ citeulike，netvibes，twitter，technorati，美味，linkedin，facebook，stumbleupon，digg，google，更多”，pubid：“ ra-4dff56cd6bb1830b”}; var addthis_config = {“ data_track_addressbar”：true，“ ui_click”：true};添加到候选列表链接永久链接http://dx.doi.org/10.1080/13506285.2011.594459
