The Effect Of Mobile Phone Deprivation On Attentional Bias Of Mobile Phone Addicts

Many studies have explored the attentional bias of addicts and found that addicts have attentional bias to addiction-related cues or negative emotional information,However,there were few studies on the characteristics of attentional bias in mobile phone addicts,and no studies have manipulated the mobile phone use experience of mobile phone addicts,such as mobile phone deprivation.In order to explore the effect of cell phone deprivation on attentional bias of mobile phone addicts,the following three studies were conducted:In study 1,457 college students were recruited by questionnaire.The results showed that:moderate and severe addiction on mobile phone accounted for 32.7%and 6.6%respectively.Mobile phone addicts spend 375.98 minutes one day averagely,and unlock the phone every 19.77 minutes.Mobile phone addicts commonly used 10 kinds of mobile phone APP for WeChat,QQ,Taobao,Pay treasure,Weibo,BiliBili,Netease cloud music,Zhihu,Baidu cloud,Meituan.In the study 2,43 mobile phone addicts were randomly selected from Study 1,and were divided into mobile phone deprivation group(21)and the control group(22).First,the subjects completed the mobile phone craving scale(pre-test).The mobile phone deprivation group was not allowed to use mobile phone during the deprivation period,while the control group was allowed to use mobile phone.Then they were asked to complete the mobile phone craving scale(post-test);Finally,they performed cue-target task.A 4-factor mixed experimental design of 2(group:mobile phone deprivation group,control group)x2(cue validity:effective,ineffective)×2(SOA:500,1000)x2(image type:mobile phone related images,neutral images)was used in this study.The results showed:the RT(response time)when the cue was valid was significantly shorter than that when the cue was invalid;the RT of SOA=500ms is significantly longer than that of SO A=1000ms;when SOA=500ms and the cue was valid,the RT of the control group on the mobile phone-related picture was significantly shorter than that on neutral picture,while the RT of the deprivation group was not significantly different between them,which indicated that the control group had attentional bias on mobile phone related cues,while the deprivation group did not.The results indicated that mobile phone addicts showed attention bias to mobile phone related cues,but the mobile phone deprivation may impair their attentional bias.In order to explore the physiological mechanisms during the mobile phone deprivation,the third study was conducted.In the study 3,54 mobile phone addicts were randomly selected from Study 1,and were divided into the cellphone deprivation group(28)and the control group(26).The procedure was similar to study 2,except that skin electrical signals and ECG signals were collected during the deprivation phase.The experimental design was same to the second study.For the deprivation group,the post-test scores on mobile phone craving were significantly higher than the pre-test;the heart rate of deprivation group decreased significantly and RR interval of deprivation group increased significantly after deprivation;when the cue was invalid,RT of mobile deprivation group significantly shorter than that of control group,while when the cue was valid,there were no significant differences between two groups.These results suggested that mobile phone deprivation may enhances attentional orientation ability.In conclusion,this study found that mobile phone deprivation weakens the attentional bias of mobile phone addicts to mobile phone related cues,and enhances the attentional orientation ability of mobile phone addicts.This study initially revealed the effects of mobile phone deprivation on the cognitive ability of mobile phone addicts,providing an empirical basis for future research in the field of mobile phone addiction,and enriching the theories in the field of mobile phone use and attentional bias.
