【摘要】：采用双任务范式并结合眼动追踪技术,探讨线索类型和奖赏对事件前瞻记忆的影响,结果发现:1.前瞻记忆成绩的线索类型主效应显著,并列、前置条件下成绩最好;2.奖赏可以提高前瞻线索的觉察率,也会抑制前瞻线索的觉察,但对后置有靶任务条件下前瞻线索的觉察没有显著影响;3.后置有靶条件下前瞻线索的眼动注视时间显著小于后置无靶条件。这些结果说明,工作记忆中可能存在优先加工缓存机制,保存前瞻线索信息,中央执行系统在每次新任务开始时迅速激活缓存机制并决定是否启动前瞻任务模式;优先加工缓存的激活概率可因奖赏、刺激重复出现等因素而增强,激活后使用与非前瞻任务不同加工通道独立加工。
[Abstract]:The effects of clue type and reward on event prospective memory were investigated by using dual task paradigm and eye movement tracking technique. The results showed that: 1. The main effect of the clue type of prospective memory score is significant, juxtaposition, the result is the best under the front condition; 2. Reward can improve the detection rate of prospective cues, but also inhibit the detection of prospective cues, but has no significant effect on the perception of prospective cues under the condition of post-target tasks. 3. The time of eye movement and fixation under the condition of posttarget was significantly less than that of the condition without target. These results suggest that there may be a preemptive cache processing mechanism in the working memory, and the central execution system can quickly activate the cache mechanism at the beginning of each new task and decide whether to start the forward-looking task mode. The activation probability of preferential processing cache can be enhanced by reward, stimulus repetition and other factors. After activation, the processing channel is independent from that of non-prospective task.
