负性面孔的工作记忆离线态存储不影响在线态存储
The passive storage of negative facial expressions in working memory does not affect the active state storage
摘要
Abstract
Visual working memory(VWM)is a cognitive system responsible for the temporary storage and manipulation of visual information and serves as a cornerstone for high-level social cognition.State-based models propose that memory representations are hierarchically organized:items within the focus of attention are maintained in an active state,while those outside this focus are retained in a passive state.Previous research investigated the passive storage mechanisms predominantly employed simple color stimuli,demonstrating that passive memory storage operates independently from active memory processing.However,in daily-life context,facial information processing is critically important for human social interactions.It remains unclear whether variations in the emotional valence of faces retained in the passive state affect concurrent active memory processing. To address this question,this study adopted a sequential presentation memory task involving 22 college students,who were instructed to memorize two sequentially presented arrays containing face stimuli.The first array(M1)was expected to enter the passive state during the active maintenance of the second array(M2).The emotional valence of face stimuli in M1 was either angry or neutral,whereas M2 always contained neutral faces.Behavioral performance and EEG neural activities were recorded,including late positive potential(LPP,indexing encoding attention),contralateral delay activity(CDA,reflecting active memory storage),and the whole-trial neural decoding of memory representations. Behavioral results showed that the emotional valence modulation of M1 had no significant impact on performance related to M2.Consistently,neural indices suggested functional independence between active and passive storage states.Specifically:1)during the encoding of M2,parieto-occipital LPP amplitudes did not differ as a function of M1's emotional valance,indicating that attentional resource allocation remained unaffected;2)multivariate decoding of M2-related maintenance-phase activity yielded no distinguishable neural patterns between angry-and neutral-face in M1.Moreover,time-generalization analysis confirmed that passive representations lacked cross-phase generalizability. These findings support the notion of resource independence between VWM active and passive states,indicating that emotional representations in the passive state do not influence ongoing memory processing.These results extend the domain-general characteristics of passive storage to complex socially relevant stimuli,and highlight the adaptive efficiency of VWM in processing sequentially presented facial information.Overall,the present study demonstrates that emotional information stored in the passive state does not interfere with concurrent active processing of facial stimuli.关键词
