【摘要】：采用雙任務范式并結(jié)合眼動追蹤技術,探討線索類型和獎賞對事件前瞻記憶的影響,結(jié)果發(fā)現(xiàn):1.前瞻記憶成績的線索類型主效應顯著,并列、前置條件下成績最好;2.獎賞可以提高前瞻線索的覺察率,也會抑制前瞻線索的覺察,但對后置有靶任務條件下前瞻線索的覺察沒有顯著影響;3.后置有靶條件下前瞻線索的眼動注視時間顯著小于后置無靶條件。這些結(jié)果說明,工作記憶中可能存在優(yōu)先加工緩存機制,保存前瞻線索信息,中央執(zhí)行系統(tǒng)在每次新任務開始時迅速激活緩存機制并決定是否啟動前瞻任務模式;優(yōu)先加工緩存的激活概率可因獎賞、刺激重復出現(xiàn)等因素而增強,激活后使用與非前瞻任務不同加工通道獨立加工。
[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.
