Effects Of HD-tDCS Stimulation On The Left And Right Dorsolateral Prefrontal Cortex On Privacy Disclosure

In the digital age,privacy is a widely studied topic,and privacy disclosure refers to users’ disclosure of their identity,address,health,financial and other information to others.In modern life,we often have to face the choice of privacy disclosure,using private information in exchange for access to different websites to meet our social,shopping,and medical needs.At the same time,information security issues abound,with third-party organizations holding information often prone to larger leaks and active disclosure by users,which in the long run can have an impact on their information security.Privacy disclosure is related to the dorsolateral prefrontal lobe(DLPFC)of the brain,a behavior that involves the mental process of inhibition,positive valence assessment,and decision making under the influence of the dorsolateral prefrontal cortex.Thus,the dorsolateral prefrontal lobe plays an important role in privacy disclosure decision making.High-precision transcranial direct current stimulation(HD-t DCS)is an emerging non-invasive brain stimulation technique that can stimulate the subject’s cerebral cortex and alter behavior while ensuring that the brain is non-invasive,thus exploring the direct causal relationship between brain regions and behavior.The left and right cortices of the dorsolateral prefrontal region play different roles in privacy disclosure decision making,therefore,the present study aimed to investigate the different effects of HD-t DCS on bilateral brain regions stimulated separately in privacy disclosure decision making scenarios,thus aiming to design two experiments:(1)To analyze the attitudes and intentions of HD-t DCS stimulation of the right dorsolateral prefrontal lobe affecting privacy disclosure.(2)To analyze HD-t DCS stimulation of the left dorsolateral prefrontal lobe to influence attitudes and intentions of privacy disclosure.Study 1 analyzed HD-t DCS stimulation of the right dorsolateral prefrontal lobe thereby influencing privacy disclosure.One hundred and twenty subjects were recruited for the study,and the stimulation location was the right dorsolateral prefrontal lobe,which was divided into anodal,cathodal,and pseudo-stimulation.It was found that cathodal stimulation significantly increased the subjects’ attitudes and intentions toward privacy disclosure,and men’s intentions toward privacy disclosure were significantly higher than those of women.This suggests that privacy disclosure decisions are modulated by the right dorsolateral prefrontal lobe,possibly due to the existence of an inhibitory process of perceived risk in privacy disclosure,where individuals reduce privacy disclosure behavior by inhibiting the tendency to choose for privacy disclosure behavior,and the right dorsolateral prefrontal lobe,a functional brain region that inhibits this behavior,allows subjects to increase the probability of choosing privacy disclosure.This result demonstrates that HD-t DCS stimulation of the right dorsolateral prefrontal lobe has a significant role in altering privacy disclosure.Study 2 examined the effect of HD-t DCS stimulation of the left dorsolateral prefrontal lobe on privacy disclosure.The study re-recruited 120 subjects,ensuring no replication of subjects and studies,and the stimulation location was the left dorsolateral prefrontal lobe,divided into anodal,cathodal,and pseudo-stimulation.It was found that the cathodal stimulus significantly reduced the subjects’ attitudes and intentions regarding privacy disclosure.This indicates that the privacy disclosure process is influenced by the left dorsolateral prefrontal lobe,which may be due to the fact that privacy disclosure involves the mental calculation process of value judgment and benefit estimation,and the left dorsolateral prefrontal lobe is responsible for value reward and focus on the proximal benefit,which leads to subjects’ greater desire for the benefit from disclosure.By inhibiting the left brain region,individuals perceived less value and thus reduced disclosure behavior.The results demonstrate the role of the left dorsolateral prefrontal lobe in privacy disclosure and further elucidate the neural mechanisms underlying privacy security issues.The results of this study have theoretical and practical implications,broadening the neural mechanisms of privacy disclosure decision research,using non-invasive brain stimulation techniques to study causality,and by means of interventions,may provide more credentials for future privacy-related clinical research,contributing a neuroscientific perspective to computational models of privacy.
