Study On Response Inhibition Of Mobile Phone Dependent In Acute And Chronic Stress Situations

The objective of this study was to explore whether there are differences bet ween individual response inhibition of mobile phone addicts in different degrees when performing the stop signal task of mobile phone related materials and irrel evant materials under acute and chronic stress situations.At the same time,acco rding to the results,the possible causes of mobile phone addiction behavior in th e state of stress are analyzed.This study was divided into acute stress and chronic stress.Study is a acute stress conditions,based on mobile phones related materials and has nothing to do with the stop signal task of material,adopting 2(pressure:high pressure vers us low pressure)x 2(phone:phone rely on high vs low mobile phone dependen t)x 2(experimental materials:mobile phones related material vs.irrelevant mate rial)mixed experimental design three factors,including high and low pressure,hi gh and low dependence on a cellular phone for variables between groups,stop s ignal task of experimental materials for the variables in the group.The dependen t variables were non-signal reaction time(NSRT)and stop-signal reaction time(SSRT),and the accuracy of non-stop tasks.First,the mobile phone addiction in dex scale was used to measure college students.According to the score of mobil e phone dependence and scale dimensions,the screened subjects were randomly divided into 1 group with high mobile phone dependence,2 groups with low mo bile phone dependence,and 1 group with low mobile phone dependence.Respon se inhibition was measured by estimating task initiation pressure and stop signal task.For the control group(high cell-phone dependence 2 group and low cell-ph one dependence 2 group),only cell phone-related and unrelated experimental mat erials were used for the stop signal task.Study two is chronic stress conditions,the implementation of mobile phones related materials and has nothing to do with same material of the stop signal t ask,using 2(high vs.low pressure)x 2(phone rely on high vs low mobile ph one dependent)x 2(mobile phones related material vs.irrelevant material)mixed experimental design of three factors,high and low pressure,high and low depe ndence on a cellular phone for variables between groups,mobile phone related a nd unrelated materials for the variables in the group.The dependent variables we re NSRT and SSRT,and the accuracy of tasks without stop signal.First distribut ion of 350 by the"mobile phone addiction index scale"and"college students str ess scale"questionnaire of screening of the subjects,matching the 100 subjects,divided into four groups to stop signal task,the result of the data was analyzed,and discussed the different mobile phones with chronic stress dependence of the subjects,under the condition of different experimental material to stop signal ta sk,response inhibition is affected.After data analysis,the following conclusions are drawn:Research discovery without stop when the signal response(Non-signal rea ction time,NSRT),a stop when the signal response(stop-signal reaction time,SSRT)and stop signal success inhibition rate index of three,high mobile phone dependent response inhibition ability was obviously lower than the mobile phon e depend on the person's ability to bad[F(1,96)=12.86,p<0.001,?_?~2=0.12,F(1,96)=13.657,p<0.001,?_?~2=0.125,F(1,96)=9.654,p<0.05,?_?~2=0.091];Participants in the reaction speed of mobile phone related experimental materials significantly slower than reaction speed of mobile phone has nothing to do the experiment materials[F(1,96)=23.127,p<0.001,?_?~2=0.194,F(1,96)=116.365,p<0.001,?_?~2=0.548,F(1,96)=4.907,p<0.05,?_?~2=0.049].In index of NSRT,subjects un der high stress response inhibition ability significantly than the subjects under lo w stress response inhibition ability difference[F(1,96)=4.655,p<0.05,?_?~2=0.05],acute stress and experimental materials exist borderline significant[F(1,96)=3.487,p=0.06>0.05,?_?~2=0.035].In the SSRT index,interaction between acute str ess and cell phone rely on two significant[F(1,96)=7.153,p<0.05,?_?~2=0.069];Experimental materials,the mobile phone depend on the interaction and stress t hree significant[F(1,96)=6.368,p<0.05,?_?~2=0.062].The two found in NSRT,SSRT and stop signal task success inhibition rate i ndex of three,high mobile phones dependence group and low dependence on gr oup differences significant[F(1,96)=6.254,p<0.05,?_?~2=0.061;F(1,96)=6.003,p<0.05,?_?~2=0.049;F(1,96)=4.615,p<0.05,?_?~2=0.046].The response inhibiti on ability of the high cell-phone dependence group was worse than that of the l ow cell-phone dependence group.There was no significant difference in response inhibition between subjects under high pressure and those under low pressure.I n NSRT and SSRT two indicators,the participants in the mobile phones related experimental materials and irrelevant material performance differences significant[F(1,96)=39.606,p<0.001,?_?~2=0.292,F(1,96)=149.179,p<0.001,?_?~2=0.563].S uccess in a stop signal task index of inhibition rate,cell phone dependence and the interaction of the chronic stress significantly[F(1,96)=4.945,p<0.05,?_?~2=0.049].The study came to the following conclusions:(1)compared with those with low cell phone dependence,the response inhib ition of those with high cell phone dependence was significantly worse.(2)in the acute stress situation,compared with the low pressure state,the i ndividual showed a decrease in inhibition under the high pressure state.In the c hronic stress condition,the decrease of response inhibition in the high stress con dition was only found in the high cell-phone dependence group.(3)in the acute stress situation,the response inhibition of the individuals wi th high stress and high cell-phone dependence was the lowest,and the response inhibition of the individuals with low stress and low cell-phone dependence was the highest.In chronic stress,however,this was only seen in individual indicator-s.(4)in the case of acute stress,both high and low cell-phone dependence gr oups were significantly affected by stress.In the case of chronic stress,those wi th high mobile phone dependence are affected more significantly than those with low mobile phone dependence.(5)compared with the mobile phone irrelevant experimental materials,the m obile phone related experimental materials significantly reduce the response speed of individuals.
