The Effect Of Mobile Phone Dependence And Emotional Picture Type On Executive Function

Since entering the era of Internet intelligence,the level of modern technology has a stage of rapid development,and the people's material living standards have also been improving.In a living environment with sufficient material,everyone in the information network age has their own electronic products,such as mobile phones,computers,and tablets.Among them,mobile phones are the most portable electronic products and the most frequently used electronic products.With the popularity of mobile phones,the problem of mobile phone dependence has begun to appear.Mobile phone dependence refers to the problematic behavior of individuals who use mobile phones indiscriminately for a long time,which causes obstacles in social life and work.In previous studies,mobile phone dependence will have a certain negative impact on individuals' physiology,psychology,cognition and behavior.Executive function is the advanced thinking ability required by individuals to recognize things and rules.It is divided into three parts: inhibition,working memory updating and switching.And executive function is divided into purely cognitive category "cold" executive function and emotionally involved "hot" executive function.This study starts from the cognitive and psychological aspects,and uses a combination of questionnaire and experimental methods to systematically study the effects of mobile phone dependence and emotional picture processing on individual executive functions.In the previous questionnaire research,the smart phone addiction scale for college students was distributed through the Internet survey,and 690 valid questionnaires were collected.Based on the analysis of the questionnaire results,the score standards for the high and low mobile phone dependence groups were formulated,and participants were invited to participate Follow-up experimental research.In the follow-up experimental research,the first experiment adopts the stop signal paradigm to study whether mobile phone dependence and emotional picture type have an effect on the inhibition of individuals.A total of 96 subjects were recruited in the experiment,using 2(group: high mobile phone dependence group/low mobile phone dependence group)× 3(emotional stimulation type: positive/neutral/negative)× 3(grade: senior,senior/ Sophomore,junior/graduate)mixed experiment design.Among them,the mobile phone dependent group and grade are the inter-group variables,and the emotional picture type is the intra-group variable.Experiment 2 adopts the N-back task paradigm to study whether mobile phone dependence and emotional picture types have an effect on individual working memory updating.A total of 81 subjects were recruited in the experiment,using 2(group: high cell phone dependence group/low cell phone dependence group)× 3(emotional stimulation type: positive/neutral/negative)× 2(task difficulty:0-back/ 2-back)× 3(grade: freshman,senior,second,junior,and graduate student).Among them,the task difficulty factor is added,and the task difficulty variable is the variable within the group.Experiment 3 adopts the interval conversion paradigm to study whether the mobile phone depends on the emotional picture type to affect the individual conversion function.A total of 91 subjects were recruited in the experiment,using 2(group: high cell phone dependence group/low cell phone dependence group)× 2(emotional stimulation type: positive/negative/neutral)× 3(grade: senior,senior/ Sophomore,junior/graduate)mixed experiment design.The results of the study show that in terms of inhibition,in the second and the third year groups,mobile phone dependence will have a negative impact on the individual's inhibition ability,and individuals with a high degree of mobile phone dependence perform poorly in inhibiting control functions.Regarding the refresh function,the task difficulty factor will have a significant impact on the individual refresh function,and the individual performs better under low-difficulty conditions.Under low-difficulty conditions,individuals perform better in refreshing functions when processing neutral emotional stimuli;while under high-difficulty conditions,individuals perform better in refreshing functions when processing positive emotional stimuli and negative emotional stimuli.Regarding the conversion function,the problem of mobile phone dependence will have a positive impact on the cognitive conversion function of the individual,and individuals with a high degree of mobile phone dependence perform better in the cognitive conversion function.The performance of conversion function when processing negative emotional stimuli is weaker than when processing neutral emotional stimuli.
