| Modern society is a information society, people living there are a lot of infor-mation in the environment, everyone should learn to in the information sea, due to the limitations of human attention to system capacity, this information can rarely part of being noticed by the people, that is to say, our cognitive mechanism has the function of "filter" that is based on the current behavior of the target and the environments for se-lective information processing. And selective attention in what stage of cognitive pro-cessing is always pay attention to the research in the field of early and late two model is the focus of debate. Thought, the selective attention in perceptual processing stage; While the latter thinks that selective attention in stimulating reaction stage. Contrary to the classic view, the current study about spatial attention, selective attention in percep-tual processing or reaction phase can change according to the task, to a certain degree, and pay attention to the early and late selection, but these studies mainly focused on the field of spatial attention. Note that instantaneous release (Attentional Blink, AB) phe-nomenon found that will develop the field of research into the time dimension. Note in-stantaneous release series is more rapid at present (RSVP) paradigm, which asked par-ticipants in a series of indifferent stimulus (distraction) of these two target stimuli (the first target for T1, the second goal for T2), which can identify found that when the two goals of time interval in200～500ms, the recognition accuracy of T2. Recent studies have focused attention on transient time off window was not noticed that stimulation of the cognitive processing mechanism, to pay attention to the mechanism research pro-vides a new perspective. Note, however, instantaneous stimulus processing mechanism within the time window, controversial.Based on spatial selective attention allocation of empirical research, this study about note transient during T1off load level of high and low will affect the T2in per- ception or level by the perception of the problem put forward assumption:pay attention to the transient period, off T1perceptual load have influence on the machining mecha-nism of T2, namely perceptual load affect the selective attention processing mechanism. Past research suggests that a general stimulation, contains information about emotional stimulus have priority processing level and emotional confrontation with significant at-tention off instantaneous effect, and contains the negative emotional valence of stimulus relative to the positive or neutral emotional stimuli, to pay attention to the instantaneous has significant attention to instant off take off against the effect, therefore, this study selected negative emotional valence words and neutral for two levels. The purpose of this study is to investigate perceptual load level of emotional words note transient mechanism against the effect. If perceptual load theory is correct, then, according to a recent study described above, T1of perceptual load levels can affect not only general stimulus during the attention off instantaneous processing mechanism, should also in-fluence the high-priority information processing. To test this prediction, this study car-ried out two experiments, in order to verify the emotional word processing to the atten-tion of the instantaneous velocity of the confrontation would effect influenced by T1perceptual load.In order to test the hypotheses, this study every experiment using different meth-ods to manipulate the T1of perceptual load, no matter adopt what kind of method to adjust the T1perceptual load, this study assumes that:under the condition of low per-ceptual load levels, emotional words to the attention of the instantaneous fight off effect is not going to disappear during the attention off transient; Instead, under the condition of high perceptual load levels, emotional words can produce marked to the attention of the transient effect. Experiment1by regulating flankers tasks T1perceptual load and perceptual load on T2in note transient during impact on perception after processing, the experimental results show that under the condition of low T1perceptual load and neu-tral words of accuracy will be affected by the attention off instant reaction, and it showed significant negative words to the attention of the instantaneous confrontation effect, emotional stimulation showed obvious recognition advantage; In T1high per-ceptual load condition, the neutral words and negative words produced significant atten-tion of instantaneous effect. this result is consistent with the theory of perceptual load; Experiment2mainly discusses perceptual load level influence the mechanism of spatial attention selection process. This experiment got similar results with experiment1mode, namely under the condition of low T1perceptual load and neutral words of accuracy will be affected by the attention off instant reaction, and it showed significant negative words note transient confrontation effect, emotional stimulation showed obvious recog-nition advantage; In T1high perceptual load condition, the neutral words and negative words are produced obvious note that transient effects. In order to further clarify the T1for pay attention to the perceptual load to take off the counter effect, we made a note off transient effect size analysis. Found that T2words note instantaneous release effect of the size of the affected by T1perceptual load level, pay attention to the transient effect on the size of the T1off high perceptual load is lower than the T1perceptual load is large, compared to the T2neutral words, T2negative words note under the condition of transient effects significantly higher. And, more importantly, T1perceptual load level and there is an interaction between T2mood words and in T1under the conditions of low perceptual load, T2neutral words to the attention of the instantaneous quantity is larger, but in T1high perceptual load condition, situation, on the other hand, namely the T2negative words to the attention of the instantaneous volume is bigger. In addition, a separate T test showed that in T1under the conditions of low perceptual load, negative words almost do not produce a note that transient effects. On the contrary, when T1perceptual load level is high, pay attention to the transient effect of neutral words and the influence of negative words are very big., in other words, under the condition of low T1perceptual load and neutral words will produce more obvious note instantaneous effect, and for negative words, pay attention to the prompt to take off the not so obvious; In T1high perceptual load condition, the neutral words and negative words will produce evident in the attention of the transient effect, this result is consistent with the theory of perceptual load.In conclusion, this study found that negative words to the attention of the instantaneous fight off effect is restricted by the perceptual load level, namely negative emotional words processing advantage whether in the transient attention during continue to retain, are influenced by the perceptual load, this finding supports the theory of perceptual load, and this research is not in dispute occurs in what stage of the selective attention, but ar-gued that with multilevel selective attention mechanism, it can be change according to goals and mission requirements and behavior, reflects the central nervous system of human cognition and efficient strategy flexibility and variability, and shows its inherent ecological adaptation. |
