Impulsivity in internet addiction: a comparison with pathological gambling

Internet addiction has been considered to be associated with poor impulse control. The aim of this study is to compare the trait impulsivity of those suffering from Internet addiction with that of individuals suffering from pathological gambling. Twenty-seven patients diagnosed with Internet addiction (age: 24.78±4.37 years), 27 patients diagnosed with pathological gambling (age: 25.67±3.97 years), and 27 healthy controls (age: 25.33±2.79 years) were enrolled in this study. All patients were men seeking treatment. Trait impulsivity and the severity of the Internet addiction and pathological gambling were measured by the Barratt Impulsiveness Scale-11, the Young's Internet Addiction Test, and the South Oaks Gambling Screen, respectively. The Beck Depression Inventory and the Beck Anxiety Inventory were also administered to all subjects. Our results show that those suffering from Internet addiction showed increased levels of trait impulsivity which were comparable to those of patients diagnosed with pathological gambling. Additionally, the severity of Internet addiction was positively correlated with the level of trait impulsivity in patients with Internet addiction. These results state that Internet addiction can be conceptualized as an impulse control disorder and that trait impulsivity is a marker for vulnerability to Internet addiction.     

Reflecting Absence: Representing the Extraordinary Deaths of Ordinary Sailors in the Media

This study undertakes a comparative analysis of the commemorative discourse used by the South Korean media, family members, and the general public in response to the deaths of 46 sailors on board a navy ship that was sunk by a North Korean torpedo in 2010. It identifies differences in the methods of remembrance among the different groups, with the media focusing on human values, professional ethics, and universal norms, while family members recalled everyday experiences with the deceased and stressed acceptance of death and the general public emphasized heroism, immortality, and national solidarity. This study discusses the differences in the understanding of death between South Koreans and Westerners.     

Changes in cue-induced, prefrontal cortex activity with video-game play

Brain responses, particularly within the orbitofrontal and cingulate cortices, to Internet video-game cues in college students are similar to those observed in patients with substance dependence in response to the substance-related cues. In this study, we report changes in brain activity between baseline and following 6 weeks of Internet video-game play. We hypothesized that subjects with high levels of self-reported craving for Internet video-game play would be associated with increased activity in the prefrontal cortex, particularly the orbitofrontal and anterior cingulate cortex. Twenty-one healthy university students were recruited. At baseline and after a 6-week period of Internet video-game play, brain activity during presentation of video-game cues was assessed using 3T blood oxygen level dependent functional magnetic resonance imaging. Craving for Internet video-game play was assessed by self-report on a 7-point visual analogue scale following cue presentation. During a standardized 6-week video-game play period, brain activity in the anterior cingulate and orbitofrontal cortex of the excessive Internet game-playing group (EIGP) increased in response to Internet video-game cues. In contrast, activity observed in the general player group (GP) was not changed or decreased. In addition, the change of craving for Internet video games was positively correlated with the change in activity of the anterior cingulate in all subjects. These changes in frontal-lobe activity with extended video-game play may be similar to those observed during the early stages of addiction.     

Predispositional Engagement,Activity Engagement,and Cognition among Older Adults

ABSTRACT

We investigated interrelationships between the predisposition toward approaching experiences in a mindful and creative way, participation in specific activities, and cognition among older adults. Participants were administered a battery measuring cognition (i.e., working memory, processing speed, divergent thinking, inductive reasoning, visuo-spatial processing), activity level, and the predisposition towards mental engagement (Need for Cognition, Mindfulness, and Openness to Experience). Results indicated that predispositional engagement and activity engagement are distinct constructs that independently contribute to different aspects of fluid ability, highlighting the importance of considering both the predisposition toward mental engagement as well as the habitual tendency to participate in activities when exploring principles of cognitive optimization.     

Deliberate real-time mood regulation in adulthood: The importance of age,fixation and attentional functioning

While previous research has linked executive attention to emotion regulation, the current study investigated the role of attentional alerting (i.e., efficient use of external warning cues) on younger (N=39) and older (N=44) adults’ use of gaze to regulate their mood in real time. Participants viewed highly arousing unpleasant images while reporting their mood and were instructed to deliberately manage how they felt and to minimise the effect of those stimuli on their mood. Fixations toward the most negative areas of the images were recorded with eye tracking. We examined whether looking less at the most negative regions, compared to each individual's own tendency, was a beneficial mood regulatory strategy and how it interacted with age and alerting ability. High alerting older adults, who rely more on external cues to guide their attention, experienced a smaller decline in mood over time by activating a less-negative-looking approach (compared to their own average tendency), effectively looking away from the most negative areas of the images. More negative gaze patterns predicted better mood for younger adults, though this effect decreased over time. Alerting did not moderate gaze–mood links in younger adults. Successful mood regulation may thus depend on particular combinations of age, fixation, and attention.     

Why Reject Creative Ideas? Fear as a Driver of Implicit Bias Against Creativity

Biases against creativity seem to be activated when people are motivated to reduce uncertainty. Drawing on the appraisal model of emotion, this study tested whether and how emotions with varying levels of uncertainty appraisals affect biases against creativity. This experimental study showed that fear, characterized by a high-uncertainty appraisal, promoted implicit, but not explicit, biases against creativity more strongly than low-uncertainty emotions such as anger and happiness. Compared with individuals who experienced anger and happiness, those who experienced fear provided lower creativity ratings because of their implicit biases against creativity. These results highlight the importance of considering emotions to understand the individuals’ biases against creativity and their recognition of creative ideas.     

The Effects of Marital Conflict on Korean Children’s Appraisal of Conflict and Psychological Adjustment

This study examined the effects of marital conflict on Korean children’s psychological adjustment and appraisal of hypothetical marital conflict situations. Children between the ages of 10 and 12 were divided into “high-conflict” (n = 58) and “low-conflict” (n = 58) groups based on their self-reported degree of perceived interparental conflict in the home environment. Hypothetical marital conflict situations were provided in cartoon format, and were differentiated based conflict intensity (verbal versus physical aggression) and content (child-related conflict versus non-child-related conflict). In general, children reported greater negative affect and perceived threat to hypothetical conflict situations involving physical aggression compared to situations involving verbal conflict. In child-related conflict situations, children reported more fear of being drawn in and endorsed coping strategies that involved direct intervention. “High-conflict group” children evidenced stronger reactivity in responding to marital conflict situations in general and endorsed indirect intervention strategies—a finding previously not found in similar studies conducted with European-American children—indicating the possibility of cross-cultural difference in coping preferences in interparental conflict situations. Furthermore, “high-conflict group” children manifested more indices of maladjustment as indicated by externalizing and internalizing behavior problems, in addition to more self-reported depressive symptoms. Results highlight the effects of marital conflict on children’s psychological adjustment and indicate the possibility of cross-cultural differences in preferred coping mechanism in interparental conflict situations for Korean children.     

The impact of online brand community type on consumer's community engagement behaviors: consumer-created vs. marketer-created online brand community in online social-networking web sites

The current study proposed and tested a theoretical model of consumers' online brand community engagement behaviors, with particular attention given to online brand community type (consumer vs. marketer-created). By integrating attribution and social identity theories, this study investigated the causal linkages between intrinsic motives of altruism, social identification motivations, and online brand community engagement behaviors. The results showed that consumers' online brand community engagement intentions were indirectly influenced by the different types of communities through different levels of consumers' attributions to intrinsic motives of altruism. This study also found that, in the attribution processes, consumers' intrinsic motives of altruism motivated them to identify themselves socially with the online communities they join. Finally, this study demonstrated that the intrinsic motives of altruism and social identification motivations provided strong social incentives to motivate consumers to engage in subsequent online brand community behaviors.
