【摘要】：采用雙任務(wù)范式并結(jié)合眼動(dòng)追蹤技術(shù),探討線索類型和獎(jiǎng)賞對(duì)事件前瞻記憶的影響,結(jié)果發(fā)現(xiàn):1.前瞻記憶成績(jī)的線索類型主效應(yīng)顯著,并列、前置條件下成績(jī)最好;2.獎(jiǎng)賞可以提高前瞻線索的覺(jué)察率,也會(huì)抑制前瞻線索的覺(jué)察,但對(duì)后置有靶任務(wù)條件下前瞻線索的覺(jué)察沒(méi)有顯著影響;3.后置有靶條件下前瞻線索的眼動(dòng)注視時(shí)間顯著小于后置無(wú)靶條件。這些結(jié)果說(shuō)明,工作記憶中可能存在優(yōu)先加工緩存機(jī)制,保存前瞻線索信息,中央執(zhí)行系統(tǒng)在每次新任務(wù)開始時(shí)迅速激活緩存機(jī)制并決定是否啟動(dòng)前瞻任務(wù)模式;優(yōu)先加工緩存的激活概率可因獎(jiǎng)賞、刺激重復(fù)出現(xiàn)等因素而增強(qiáng),激活后使用與非前瞻任務(wù)不同加工通道獨(dú)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.
