视觉工作记忆中回溯线索效应的影响因素 [The Influencing Factors of Retro-Cue Effect in Visual Working Memory]
The visual working memory is a temporary storage system, which encodes, maintains and retrieves visual information. The researchers have found that adding retro-cues to the maintenance phase of memory leads to changes in participants’ memory performance, which is the retro-cue effect. The magnitude of the retro-cue effect is not set in stone, but changes with the changes of its influencing factors. However, there is no study to summarize the influencing factors of the retro-clue effect. This paper looked into the articles related to the study of the retro-cue effect and summarized the influencing factors of the retro-cue effect: memory items, maintenance interval time, interference in maint…
视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
Anti-plant Defense Response Strategies Mediated by the Secondary Symbiont
Bacterial symbionts are omnipresent in insects, particularly aphids, and often exert important effects on the host ecology; however, examples of symbionts that mediate herbivore-plant interactions remain limited. Here, three clones with identical genetic backgrounds were established: a Hamiltonella defensa-free clone, H. defensa-infected clone and H. defensa-cured clone. H. defensa infection was found to increase the fitness of Sitobion miscanthi by increasing the total number of offspring and decreasing the age of first reproduction. Furthermore, gene expression studies and phytohormone measurement showed that feeding by the Hamiltonella-infected clone suppressed the salicylic acid (SA)- a…
