Self-control makes the difference: The psychological mechanism of dual processing model on internet addicts’ unusual behavior in intertemporal choice

Does sadness bring myopia: an intertemporal choice experiment with college students

Introduction

While economics often interprets individual intertemporal choice preferences through the rationality assumption of utility maximization, the reality is that as emotional beings, individuals' preferences for intertemporal behavior are much more diverse and inconsistent. Prior research has predominantly focused on positive or negative emotions based on prospect theory, such as anxiety, anger, disgust, and depression. However, there has been relatively little research on how sadness affects individuals' preferences for immediate and future rewards.

Methods

In this study, 170 college students are recruited as participants, and their emotions are primed with a video before engaging in an intertemporal task. Covariance analysis and logit regression model are established to examine the main and interactive effects of sadness on individuals' immediate reward preferences.

Results

The findings reveal that sadness led individuals to prefer smaller immediate rewards, demonstrating a more myopic behavioral pattern, but didn't affect time discount rate. As the reward baseline increases, sadness's impact on immediate reward preferences is more pronounced, exacerbating individuals' myopic behavior.

Discussion

In conclusion, these findings underscore the importance of considering emotional states in economic decision-making models and suggest avenues for future research to explore the complex dynamics of emotions and intertemporal choices.

Relationship between an inconsistent degree of financial literacy and inconsistent decision-making in intertemporal choices

Intertemporal choice refers to the decision-making process involving trade-offs between rewards available at different points in time (such as choosing between smaller immediate rewards versus larger rewards later on). Empirical evidence often deviates from the exponential preferences predicted by the normative model. A hyperbolic discount function better mirrors individual behavior, explaining temporal inconsistency - whereby preferences vary over time by applying a higher discount in the present. Hyperbolic preferences are associated with addictive behaviors, such as smoking and alcohol consumption, as well as depression or attention deficit hyperactivity disorder. Established measures in the literature quantify the extent of deviation from exponential trend exhibited by hyperbolic preferences. In addition to behavioral and cognitive factors, it is essential to incorporate financial literacy into the examination of individual decision-making behaviors. The present study analyzes the relationship between the degree of decision-making inconsistency and the degree of financial literacy inconsistency across three dimensions: knowledge, behavior, and attitudes. It aims to illustrate while financial literacy is important, it is not sufficient to ensure rational choices. Rather, it reveals a strong correlation among its dimensions. The results of this research could be included when creating investor profiles required by MiFID, considering insights from behavioral finance studies in these profiles. What is more, understanding psychological biases that can influence financial decision-making empowers investors to make more informed decisions and avoid common pitfalls.

Problematic Use of the Internet and Well-Being among Youth from a Global Perspective: A Mediated-Moderated Model of Socio-Emotional Factors

Problematic Use of the Internet (PUI) is characterized as the inability to control one's internet use or as an excessive use of the internet that may result in social, psychological, and emotional difficulties (Fernandes et al., 2019). It is regarded nowadays as an increasingly worrisome public heath issue, especially among youth. This study explored the contexts in which youth PUI occurs and its associations with socio-emotional functioning that may lead to a decrease in one's sense of well-being. We conducted this exploration among 783 middle school students from the US (425 students; 54.27%) and Israel (358 students; 45.73%). The overall age of both samples ranged between 12 and 16 (M = 13.94, SD = 1.59). In the Israeli sample, 49.1% of the students were girls and 50.9% were boys, whereas in the US sample, 48.8% were girls and 51.2% were boys. The study examined the role of depressive mood, loneliness, resilience, self-control, and school engagement in mediating the relationship between PUI and well-being, and how country of origin might moderate these relationships. Results indicate PUI was related to lower well-being only for the US sample. Yet, for both samples, higher loneliness was related to lower well-being, and higher school engagement was related to higher well-being. A moderated mediation analysis revealed the socio-emotional variables were all mediators in these associations, but differently for each country sample. The study results are discussed according to key factors required for developing intervention programs for coping with youth PUI behaviors.

The effects of materialism and ego depletion on intertemporal choice: An event-related potential study

Objective

The study aims to promote human beings to make scientific and reasonable decisions for the long-term and beautiful future.

Methods

We designed two experiments to explore the influence of materialism and ego depletion from the perspective of behavioral decision-making and neural mechanism.

Results

In Experiment 1, there was asymmetry in intertemporal choice between gain and loss situations. In the gain situation, high materialism were more likely to choose the later and larger option (LL). However, in a loss situation, we found a reverse sign effect, and the proportion of subjects choosing sooner and smaller options (SS) increased. In Experiment 2, in the gain situation, after adding the low ego depletion task, there was a marginal significant difference between high and low materialism in the percentage of choosing LL options, F(1, 40) = 3.37, P = 0.07, η² = 0.08; After adding the high ego depletion task, the percentage of choosing LL options was no difference, F(1, 40) = 1.42, P > 0.05. In the loss situation, whether in the high ego depletion task [F(1, 40) = 2.25, P > 0.05) or in the low ego depletion task [F(1, 40) = 1.44, P > 0.05), there was no difference between high and low materialism in the percentage of choosing LL options, and they both tended to choose SS options. The EEG study showed that in high materialism, there was a significant difference between the high and low ego depletion conditions, and the N1 amplitude induced under the low ego depletion condition was larger than that under the high ego depletion condition. However, there was no significant difference in N1 amplitude between the high and low ego depletion conditions in the low materialism. The amplitude of P2 evoked in the loss situation was larger than that in the gain situation.

Conclusion

In conclusion, Materialism dominated people's intertemporal choices, and ego depletion affected the intertemporal choice to a certain extent by influencing the subjects' thinking activities. The COVID-19 epidemic maybe affected intertemporal choice indirectly by acting on materialistic values and subjects' emotions.

Carpe diem or carpe mañana? Emotion priming affects intertemporal choice among Internet addicts and normal Internet users

In this digitalized era, Internet addiction has been a severe problem that needs imperative solutions derived from the same mechanism that leads to its addiction. To uncover a more nuanced mechanism for Internet addiction in association with decision-making focus and emotions and thus generate effective interventions, we conducted three experiments to investigate how various forms of emotion priming affect intertemporal choice among Internet addicts and normal Internet users. We divided the emotions into three categories, namely emotional valence (negative and positive emotions), expected emotion type (expected regret, expected joy), and current emotion type (current regret, current joy). In experiment one, we examined the effect of two participant types (Internet addicts and normal Internet users) with three emotion valences (positive, negative, and neutral). In experiment two, we examined the effect of two participant types (Internet addicts and normal Internet users) with three current emotion types (current regret, joy, and neutral). In experiment three, we examined the effect of two participant types (Internet addicts and normal Internet users) with two expected emotion types (expected regret and expected joy). We conducted a completely randomized experimental design in each experiment and used subjective value as the dependent variable index of intertemporal choice. The results showed that the subjective value of Internet addicts was significantly lower than that of normal Internet users across three studies. The subjective value of individuals primed with positive emotions was significantly higher than those primed with negative emotions, no matter whether they were normal Internet users or addicts (experiment one). The subjective value of individuals primed with expected joy was significantly higher than those primed with expected regret, no matter whether they were normal Internet users or addicts (experiment three). When primed with current joy, however, the Internet addicts' subjective value was significantly lower than when primed with current regret, but this did not apply to normal Internet users (experiment two). These results suggest positive emotions and expected joy enhanced long-term goals and greater rewards focus on intertemporal decision-making compared to negative emotions and expected regret. However, current joy facilitated short-term goals, and smaller rewards focus on intertemporal decision-making compared to current regret. The theoretical and practical implications for Internet addiction are also discussed in this paper.

Self-Control and Problematic Internet Use in College Students: The Chain Mediating Effect of Rejection Sensitivity and Loneliness

Purpose

To explore the relationship between self-control, rejection sensitivity, loneliness, and problematic internet use in college students.

Patients and Methods

A total of 725 college students were investigated using Self-control Scale, Rejection Sensitivity Questionnaire, Loneliness Scale, and Internet Addiction Scale.

Results

① Correlation analysis showed that self-control was negatively related to rejection sensitivity, loneliness, and problematic internet use; rejection sensitivity was positively related to loneliness and problematic internet use; loneliness was positively related to problematic internet use. ② Chain mediating effect analysis showed that self-control can not only affect problematic internet use in college students, but also through three indirect paths, as follows: the mediating role of rejection sensitivity and loneliness, the chain mediating roles of rejection sensitivity and loneliness, and the mediating effect size, accounting for 9.76%, 20.73%, and 4.88% of the total effect, respectively.

Conclusion

Rejection sensitivity and loneliness played a chain mediating role in the relationship between self-control and problematic internet use in college students.

Working Memory Depletion Affects Intertemporal Choice Among Internet Addicts and Healthy Controls

Addiction to the Internet has emerged as a new kind of addictive behavior. Although previous studies have revealed that impairments in working memory led to suboptimal decision making (e.g., a greater willingness to choose smaller, more immediate rewards), little is known about how working memory affects intertemporal choice in Internet addicts and normal users. Thus, this study’s aim was to investigate the effect of working memory task on intertemporal choice in 33 participants addicted to internet and 25 healthy controls. Participants were administered (a) a test for Internet Addiction, (b) a single delay discounting self-report questionnaire (c) a working memory task. Differences between the Internet addicts and the control group were observed in terms of delay discounting rates, reaction times, and in memory accuracy rates. We observed significantly higher delay discounting rates among individuals addicted to the Internet. Moreover, it was documented that reaction times follow the 4-level working memory condition were significantly longer than follow the 2-level condition, in both the Internet addicts and the control group. The current findings suggest that Internet addicts are more likely to make short-sighted decisions than normal Internet users. The higher the level of working memory, the more likely an individual is to choose the present smaller reward, thus making short-sighted decisions, and have longer response times.

Imagining the Future: Future Imagination Training Decreases Delay Discounting Among Internet Addicts and Non-Problematic Users

To test whether future imagination can reduce the delay discounting rate of the Internet addicts, we recruited 40 Internet addicts (treatment sample) and 39 non-problematic users (control sample). We used a 2 (participant type: individuals with Internet addiction vs. non-problematic users) × 2 (training type: future event imagination training vs. control condition) × 2 (training session: first session vs. final session) mixed-subjects design to test our hypothesis. The participant type and training type were between the subjects and the training session was within the subject. Half of each sample (the Internet addicts and non-problematic users) was randomly assigned to complete five sessions of future imagination training and the other half was assigned to describe some daily events they had observed. We used the Barratt Impulsivity Scale (BIS) and delay discounting task to assess our outcome variable, such as addiction, impulsivity, and delay discounting rate. The results showed that the future imagination training significantly reduced the delay discounting rate (also for impulsivity and addiction) for both the Internet addicts and non-problematic users than the control condition. Besides, the negative effect of future imagination training on the delay discounting rates (for impulsivity and addiction) remained consistent across the five training sessions. These findings suggest that the future imagination training can be a useful approach to reduce the impulsivity among those who are addicted to the Internet.

Direct and Indirect Effects of Neuroticism on Internet Addiction in College Students: A Structure Equation Modeling Analysis

In the recent decade, increased severity of Internet addiction has been the focus of considerable attention. This research aimed to explore the relationships between neuroticism and Internet addiction. A total of 459 undergraduate students in China participating in this study completed self-report measures of neuroticism, impulsivity, and Internet addiction. The results showed that neuroticism, impulsivity, and Internet addiction were significantly and positively correlated with one other. The structural equation modeling approach indicated that impulsivity, in part, mediated the effect of neuroticism on Internet addiction. An important indirect path from neuroticism to Internet addiction through impulsivity was exposed using the bootstrap method. The outcomes of previous studies were expounded on to define how neuroticism affects Internet addiction.
