Traditionally，The main methods of psychological research are observation method、Experimental method、Questionnaire method, etc.。Where，Questionnaire is one of the most widely used methods in the field of psychology，This method is mainly to obtain the corresponding test information or specific psychological index scores by answering the response in the self -centered table。The questionnaire method can provide valuable self -perspective and rich information for research，The results obtained are easier to quantify and analyze，At the same time, it is widely used in psychological research because of its simple operation。At the same time，The questionnaire method is also questioned，The following problems are mainly existing: First of all，Because the questionnaire method is mainly to obtain the response of the subject through the formula of the table，The answer to the scale may be affected by the memory deviation of the researcher's memory to a certain extent，Poor bet365 Play online games timeliness so that it can only do forward -looking research without retrospective research。Last，The questionnaire method is easy to operate，But during measurement, it is subject to human and material resources，It is difficult to obtain multiple large -scale measurement data in a short time。Last，Because the data collection is based on the real -time feedback of the subject and the questionnaire，The results depend on the cooperation of the subject and the ability of the self -province，Therefore, it is difficult to perform when it is difficult to obtain the sample of the sample or the subject is relatively not cooperating with the test。

The rise of computer technology such as artificial intelligence provides new research ideas and methods for solving the above problems to a certain extent，One of its main ways is to adopt ecological identification method。Specifically，Ecological identification Using machine learning，Through an invasive measurement method，Realize prediction recognition of the psychological characteristics of the subject。It mainly includes the measurement method of data collection and invasion in the natural state (ecological) behavioral data collection and invasion (as shown in the figure)。Behavior data includes network behavior data、Recording、Facial video、gait video、Diary and other original data，After the measurement is authorized after the measurement, the record method of unknown measurement or not perceived the measurement during measurement，Among them, network behavior data (data on social media, etc.) is a common behavioral data source。A measure of no invasion refers to after obtaining the corresponding data，Use new media big data and machine learning technology to extract the corresponding features from the data，To associate behavior data with its corresponding psychological indicators，Create the process of predictive models based on behavioral characteristics。Bet365 app download The establishment of a good model requires a series of inspection and optimization，so that it can automatically automatically recognize the corresponding psychological indicators。

Compared to traditional psychological research methods，Ecological identification has the following more obvious advantages。First，Behavior data such as social media is relatively rich，You can also record the time point of the incident in the trial life in real time。Use these public data，The psychological state that can measure the fixed time from the event，It can be able to retrospect the psychological state before the research event occurs。Second，Behavioral data Especially data on social media allows researchers to measure psychological characteristics in a short period of time，To a certain extent, it can be able to effectively reveal the continuous change trend of psychological characteristics with less manpower and material resources。third，Use artificial intelligence technology to identify and predict the psychological characteristics of the psychological characteristics of not relying on the subjective self -report，A measure bias brought by the memories bias and forgotten effects that can be avoided to a certain extent，and can more truly reflect the psychological state that may exist at a certain time point。

　　Use network data to identify people's psychological state

During the epidemic period of new crown pneumonia，People have changed significantly，Timely understanding and analyzing people's psychological status can provide reference ideas for formulating corresponding anti -epidemic policies。In this situation，Ecological identification method shows a certain advantage。

Fixed -point analysis of the influence of special events on the epidemic on people's psychological state。Special events are often accompanied by changes in people's psychological state。Understand the effects of these special events on people's psychological state，Generally, the method adopted is based on the incident time as the node，bet365 Play online games Performance and post -test of people's psychological indicators。But，Unpredictable due to the epidemic，The use of traditional methods for retrospective studies may be affected to a large extent.，As a result, the measurement deviation。Use network data on social media，Combined with artificial intelligence's invasive measurement technology，Can be able to follow back to study the psychological state of people before the incident。Research Discovery，Compared to the qualitative of the epidemic，People show more negative emotions and negative cognition after the epidemic is qualitative; compared to Fengcheng，People show anxiety in the short term after sealing the city、Disappointment and other negative emotions，At the same time, there are corresponding changes in psychological expression。Use social media network data to combine artificial intelligence methods，Can explore the impact of special events on people's psychological state，Effective understanding and monitoring social mentality，To better take corresponding measures to promote social harmony，Jointly resist the epidemic。

Psychological state of targeted comparison of specific groups。Due to the difference in the severity of the epidemic situation in various regions，Group psychological status in different regions will also be different。Traditional questionnaires consume more manpower material resources，During the epidemic, the energy is concentrated on the protection of the epidemic during the epidemic.，Adopting traditional data collection methods may be easier to show the characteristics of low recovery rate，As a result, the psychological indicators of the targeted collection of specific groups are more difficult。

Using social media network data can obtain psychological indicators of group groups in specific regional groups in large scale。Research Discovery，In the same measures of urban measures, bet365 best casino games the two regions of Lunbari and Wuhan, China，Group psychological changes are both common and different。First，The two showed the expression of high family vocabulary and high -recognition level。Last，Lunbaridi shows a decrease in pressure level and the increase in the expression of leisure vocabulary，Wuhan shows the elevation of vocabulary such as group attention。These research results can help us understand the impact of the psychological state of the epidemic on the psychological state of the group in different regions，Take targeted psychological assistance measures according to the development stage of the epidemic，The purpose of achieving a stable social mentality。

Demonstration of people's psychological state changes during the outbreak and explore influencing factors。The occurrence of the epidemic is often a sustainable event，People may show different psychological states in different periods of the epidemic。If the traditional questionnaire measurement is used, it is required to fill in the questionnaire every day，It will undoubtedly bring additional burden to groups that are unstable psychological state，Data collection that is not conducive to long -term large -scale group psychological characteristics。Use artificial intelligence technology to analyze network data on social media，The changes in the psychological indicators of large -scale groups can be tracked for a long time。Research Discovery，People show different emotional reactions in different periods of the development of the epidemic，Such as the increase in negative emotional vocabulary during the outbreak period。，There is also a different manifestation of people's psychological cognition of "stigmatized" during the different periods of the epidemic。Not only that，Use rich social media network data，Can further explore the factors that affect people's epidemic prevention ideas。Research Discovery，Cultural factors (such as collectivism) bet365 live casino games and emotional factors (such as fear) have a joint effect in epidemic protection ideas。Such studies have long -term portrayal changes in people's psychological state，Model help researchers understand the epidemic affecting people's psychological state，Inquiry Factors of specific psychological characteristics，Can provide reference and guidance for the implementation of prevention and control measures。

In addition to using network data from social media，Ecological identification can also be applied to offline behavior data，Recognition of specific psychological characteristics and status，It mainly includes voice、Three data types of facial video and gait。Combined with artificial intelligence technology，You can identify the psychological characteristics of the subject with these data，Ru personality、Self -esteem level，You can also identify the mental health state of the subject。

Crime mental health state is after being recognized，Combined with artificial intelligence -related technologies can take corresponding intervention measures，To achieve online active prevention。Currently researching and developing virtual reality -based cognitive distortion self -service intervention system，Basic principles of cognitive behavior therapy，Take the level map mode，Divide the intervention process into three main steps，That is cognitive behavior therapy、Identification of cognitive and distorted cognitive correction。By allowing users to participate in the virtual reality interaction，Help users correct the distortion of their negative emotions，Finally let users learn to replace the past negative thinking in a positive way of thinking，and further master the corresponding behavior response skills，to achieve the purpose of psychological intervention。

In short，Use artificial intelligence and big data technology，Ecological identification can be collected in data for psychology、Provides new research ideas for psychological bet365 Play online games indicators recognition and crisis status intervention，To a certain extent to make up for the lack of traditional psychological research methods，It also opened up potential for subsequent research、Vivened data source，and provide a new form of psychological indicators measurement method。
