In everyday life, decisions are often made under stress and while being occupied with multiple tasks. It has recently been shown that acute stress impairs decision making under risk. Performing a parallel executive task also caused riskier decision making. To investigate the effects of a combination of these two factors on decision making, we conducted a(More)
Stress and additional load on the executive system, produced by a parallel working memory task, impair decision making under risk. However, the combination of stress and a parallel task seems to preserve the decision-making performance [e.g., operationalized by the Game of Dice Task (GDT)] from decreasing, probably by a switch from serial to parallel(More)
The dysfunctional behavior of excessive Internet gamers, such as preferring the immediate reward (to play World of Warcraft) despite the negative long-term consequences may be comparable with the dysfunctional behavior in substance abusers or individuals with behavioral addictions, e.g. pathological gambling. In these disorders, general decision-making(More)
Excessive or addictive Internet use can be linked to different online activities, such as Internet gaming or cybersex. The usage of Internet pornography sites is one important facet of online sexual activity. The aim of the present work was to examine potential predictors of a tendency toward cybersex addiction in terms of subjective complaints in everyday(More)
The phenomenon of excessive or pathological Internet use has been investigated in the last decades in order to reveal psychological correlates as well as potential treatments. A key element of the respective research and clinical practice is a valid and reliable diagnosis of pathological Internet use. One of the most frequently used questionnaires is(More)
Executive functioning is supposed to have an important role in decision making under risk. Several studies reported that more advantageous decision-making behavior was accompanied by better performance in tests of executive functioning and that the decision-making process was accompanied by activations in prefrontal and subcortical brain regions associated(More)
Recent research suggests two ways of making decisions: an intuitive and an analytical one. The current study examines whether a secondary executive task interferes with advantageous decision-making in the Game of Dice Task (GDT), a decision-making task with explicit and stable rules that taps executive functioning. One group of participants performed the(More)
We investigated the effects of intelligence, decision-making strategies, and general cognitive styles on the role of feedback in making decisions under risk. A total of 100 healthy volunteers were assessed with the Game of Dice Task (GDT). A total of 50 participants performed the original GDT, and 50 participants performed a modified GDT in which no(More)
We investigated the role of feedback processing in decision making under risk conditions in 50 patients with amnesia in the course of alcoholic Korsakoff's syndrome (KS). Half of the patients were administered the Game of Dice Task (GDT) and the remaining 25 patients were examined with a modified version of the GDT in which no feedback was provided.(More)
Background and aims Cybersex addiction is discussed controversially, while empirical evidence is widely missing. With respect to its mechanisms of development and maintenance Brand et al. (2011) assume that reinforcement due to cybersex should lead to the development of cue-reactivity and craving explaining recurrent cybersex use in the face of growing but(More)
