Eye movement method is to watch、Jumping、Pupil diameter changes and other eye movements to track and record，Based on "Based on" Consider "，Watching duration reflects the hypothesis of cognitive efforts，Capture "Nature" visual perception，Based on this "push" thinking。

Specifically，The advantages of eye movement method mainly include the following aspects: providing millisecond -level fine real -time visual data，Combined screen recording，The completion process of the complete record and reproduction of the language task，It is difficult to obtain the fleeting fine data，retrospective report、Interview because afterwards，Need to depend on test memory，Therefore, there are often omissions; it has a good ecological effect because it is not required to perform additional tasks at the same time;、Manual permits also make the experimental process more natural; it is easy to quantify the effort of paying attention to the bet365 live casino games allocation of attention resources or cognitive efforts;，Eye movement data is relatively more objective; because it is performed at the computer interface，Research on the task of computer as the medium has an advantage，If a computer -based test。

　　Flexible use of eye movement

Eye movement method has applications in many areas of foreign language applications。The typical research in some areas below analyzes the research paradigm。

C. J. Weir means，Eye movement method has been used in a cognitive process research in foreign language testing or evaluation，Describe and diagnose the test process of the learner，Explore the "Cognitive Effect" of the test questions。Take the test research on the completion of the blanks as an example， G. McCray and T. Brunfaut Study different levels of two -character learners to complete the difference in cognitive processing process when completing the PTE academic English test.，Explore the concept of investigation of this type of topic。This research divides 6 types of interest areas，Cover the test area、text area、Empty sentence、Both sides of the space、option library and candidate words。At the same time，7 indicators are applied to this study，Involved (relative) gaze time、Number of access to the option library、The regression slope of the viewing time and frequent words，Corresponding to the overall processing、Text processing、Machining of three levels of task processing。The results of this study found that cognitive processing is related to the level of candidates，Low points will use more cognitive efforts for local、Low -level processing。Research believes what the test questions are related to the level of candidates，For low points，Test questions mainly trigger low -level processing。Follow -up research can consider tracking eye movements and other means，Retrospective report、Circular recording, etc.，Triangular verification of data to achieve data。Another，This research bet365 live casino games is based on the individual differences of the group，In -depth exploration of eye movement characteristics of typical cases，or discovery that is different from group characteristics。Comparison of comparison，Eye movement research in the field of domestic two -character testing is still in its infancy。

Eye Tracking Technology，Especially the combination of keyboard records and eye movement tracking technology，"Black Box" that allows people to understand the translator's cognitive psychological process，The reading comprehension process of analyzing translator、The synergy process of reading comprehension and output has a profound impact。Feng Jia's translation direction、The relationship between the difficulty and the reading process of the text and the translation process was studied.，Interesting area involves source text、Target text and the entire work area，14 eye movement indicators。Discover，Translation (English translation) is more cognitive resources than translated (Chinese translation) in terms of source text reading，The target text consumption of the target text is significantly more attention than when translated; the lower the text difficult，The less attention assigned to the familiar stage，Difficulty to allocate the overall attention and draft、Resource allocation in the revised stage does not have a significant effect。Feng Jia used a variety of eye movement indicators，But the effectiveness of the indicator seems to be able to discuss in -depth; in addition，Maybe due to the accuracy of eye movement，Its difficulty analysis has not involved sentences、Vocabulary level。Current，More research in English translation，and the research on Chinese translations is still obviously less。

Eye movement method can also help examine the cognitive processing characteristics of the reading process of the two -language learner，Reveal the mechanism of the effect of reading understanding。Research from Shen Yinglun and bet365 Play online games others pay attention to the correct rate of reading comprehension、Effect of reading speed，Among them, the reading speed is measured at the eye movement indicator。The reading material of the research is a explanation text of 206 words，Show in two screens。After each time it is presented, the key is required to answer two judgments。Eye movement indicators used are divided into two levels，One is the chapter layer，Including total reading time、Watching times、Number of views、Average gaze time、Average eye jump; the second is the vocabulary layer，Including the jumping rate of high -frequency words and low frequency words、The first view time、Staring time、Total Watching Time。Discover，Reading many times does not significantly improve the correct rate of reading understanding，But the early and advanced reading indicators were found to have a significant effect，It shows that the reading efficiency is effectively improved，Among them, the promotion effect on low -frequency word recognition is significantly greater than the promotion effect of high -frequency word recognition。This research is based on the right judgment question to test the reading comprehension，But the results of this type of question type are easily disturbed by speculation，The conclusion conclusion that only rely on the decline of eye movement indicators seems to lack persuasion。In addition to the effect of repeated reading，You can also use eye movements to track more foreign language reading topics，Rulies of vocabulary reclaim、Reading style or the relationship between reading purpose and reading processing process、Vocabulary and grammar acquisition in the reading process、Academic English reading process, etc.。

From the analysis of the above typical research, it can be seen，The use of eye movement tracking can be combined with research topics、The research goals are flexible。For example，Fill in the blanks above、Translation、Reading Reading Research in the Interest Bet365 app download Area Division、The selection of eye movement indicators is different。End with the test questions to study and follow multiple interest areas，Cover the test area、text area、space area、Option Zone, etc.，Division of three levels of processing，is the overall、Text and task processing。The interest area used in translation research at the least，Eye movement indicators the most，The reason is that it aims to deepen the allocation of cognitive resources in Yuanwen District and the translation area。Reading research is more concerned about the eye movement indicators related to the space dimension related to the location of the eyes，Specifically includes jumping distance、Watching position、Watching times、Jump reading rate、Re -view ratio and return number of views。

　　Can't ignore the limitations of eye movement

It is related to the questioning of "Eye Brain Assumption" that is what you see.，Eye movement features are not direct reflection of thought，Need to be reasonable，Answer to obtain research questions。The indirect nature of overcoming the method of eye movement needs to be followed by the research paradigm，You need to use cross -verification，If the use of sound thinking method is combined、Looking back on oral report、Keyboard records、Questionnaire survey、Interview、screen recording and other methods，Collect diversified data，Cross Verification Research Assumption，More comprehensive interpretation of the research results。

In terms of ecological effects，Eye Tracking is an experimental environment after all，different from the natural environment。Use of the chin in some experiments，It also makes reading or watching behaviors less natural。Eye Tracking is also reaction to the cognitive process，For example, if you are interview, you may restrain your sight without leaving the screen，Study on visual translation must also consider the impact of speaking on eye movements。Material presentation，Due to technical conditions bet365 best casino games limit，Often changes the materials，If zooming in the font、Increase the running distance、Re -arrange，and presentation of the longer materials for the more materials。Another language task is sometimes not real，For example, y. Tono places a sentence containing versatile words on the top of the dictionary page and requires to query its meaning。

Data collection technology has certain limitations。First, the sampling rate of the eye movement itself。Low sampling rate causes not to fully record the actual see。The second is allowed head to move、Manual (such as keyboard use)，or the correction of the eye movement in the condition of the trial sitting position、Compensation、Recovery ability。Because of this，Writing、The use of eye movement data in translation research is greatly limited。Third, when the screen recording is played and analyzed the watch trajectory，Need to recognize the viewing point shown，It is just part of the high -definition vision of the central nest of the human eye，In addition, you cannot ignore the deputy central nest、Machining peripheral vision。

Last，Great eye movement data brings difficulties to analyze and use。Assessing Writing 2018 Special Editor -in -chief S. Chan affirmed the potential role of eye movement tracking in formation of formation，But as she said，"The amount of data will be huge"，Therefore, "need，To choose the most useful data for evaluation and decision "。

Eye movement Tracking because of its cognition、Note the detailed record of the process、Quantitative analysis，Research on the application of foreign language application brings new directions and inspiration。Multiple mutual evidence helps to overcome its limitations，get comprehensive、Reliable conclusions on the process。I look forward to more studies on the use of eye movements to explore domestic and foreign language acquisition questions。Some possible research areas include translation test、Sentence translation process and strategy、Read Bet365 app download the follow -up process、Data retrieval in writing、Read test、Teaching effect、Evaluation of formation、Analysis of language、Video Learning、Analysis of language、Language attitude, etc.。Eye movement can also be with other psychology、Cognitive measurement means (such as emotional measurement、Electricity) Carrying out research。
