媒体多任务经验对不同注意模式下内隐记忆的影响

本研究采用经典背景线索范式，在分布式注意（限制眼动）和集中式注意（自由观看）两种模式下考察不同媒体多任务经验者的内隐记忆表现。实验1要求被试在学习阶段自由观看场景并搜索目标，在测试阶段限制眼动并使用外周视野搜索目标。实验2将学习、测试阶段的注意模式反转。结果发现，高媒体多任务经验者在两种注意模式下均表现出背景线索效应；低媒体多任务经验者仅在集中式注意模式下表现出背景线索效应。结果表明，高媒体多任务经验者在分布式注意模式下存在一定的内隐记忆优势。

The Influence of Media Multitasking Experience on Implicit Memory in Different Attention Patterns

In this study, the classic contextual cueing paradigm was used to investigate the implicit memory of different media multitaskers in the distributed attention mode (limited eye movement) and focused attention mode(free viewing). In experiment 1, participants could freely move their eyes and search the target in the learning phase. On the contrary, participants were required to fixate the screen center and use peripheral vision for search in the testing phase. Experiment 2 reversed the conditions of attention in the learning and testing stages. The current results revealed that heavy media multitaskers showed contextual cueing effect in both attention modes while light media multitaskers only showed such effect in the focused attention mode. The results showed that heavy media multitaskers had better performance on the contextual cueing effect task under the distributed attention mode, indicating that heavy media multitaskers have some specific cognitive advantages.
