The Process Of Faking Responses In Personality Tests:A Study On The Internal Mechanism Differences Between Social Desirability And Job Desirability

As an effective tool to measure individual personality traits and predict employee performance,personality test is favored by many enterprises and organizations.However,in order to be employed by enterprises,individuals often faking in personality tests according to position requirements,resulting in distortion of test results and affecting the actual utility of personality tests.Due to the lack of understanding of the internal process of faking,and often confuse the faking response based on job desirability with social desirability,there is no particularly accurate and effective method to identify faking.Therefore,we explored the internal mechanism of social desirability and job desirability,clarified the differences between them,and mined more information about the response process of faking to lay a foundation for effective identification of faking.The research is mainly divided into three parts:the pre-study evaluates the job desirability of the Big Five Inventory(BFI-2),which lays a foundation for the subsequent analysis of the internal process of faking response.In the first study,a questionnaire was used to measure the influence of social desirability and job desirability on the score of Big Five personality Inventory.In study 2,the response time,fixation duration,fixation count,pupil size,heart rate and galvanic skin response of the big five personality scale overall,each dimension of items and different job desirability items were measured by eye tracker and multichannel physiological recorder under the fake good situation,honest situation and ideal employee situation.This paper explores the internal mechanism differences between social desirability and job desirability from two aspects of cognitive processing and emotional arousal.The results showed that:1.Job desirability intentionally distort the truth more than social desirability and answer more in the direction of job expectations.2.The cognitive processing of social desirability conforms to the semantic-exercise model.The cognitive processing of job desirability is mixed processing:the items are appreciated for your job matched the semantic-exercise model,while the items are not appreciated for your job and the items no job desirability,semantic processing schema is blocked,and the cognitive processing was similar to that of honest answer.3.The cognitive processing of social desirability and job desirability are different.Specifically,on the items that are appreciated for your job,both of them are consistent with semantic-exercise model,and there is no significant difference;On the items that are not appreciated for your job and no job desirability,the cognitive processing of job desirability was more complex and the cognitive load was higher than that of social desirability.4.The emotional arousal level of job desirability was higher than that of honest answer,there was no significant difference in emotional arousal between social desirability and honest response.5.There was no significant difference in emotional arousal between social desirability and job desirability.This study found the internal mechanism differences between social desirability and job desirability,which enriched the internal process of faking and provided experimental basis for effective identification and control of faking.
