For example, Boulanger et al. Likewise, Mitchell et al. Schmitt et al. The inconsistencies in the results of these studies could be explained by factors, such as differences of the samples selected. Psychopathy as multi-dimensional construct is likely to have different relations with decision-making in different dimensions Hughes et al. For example, Beszterczey et al. Dean et al. Similarly, Hughes et al. However, in Hughes et al. Together, these studies provide mixed evidence for the relationship between psychopathy facet or factor and IGT performances.
In the IGT, the probabilities of outcome are unknowingly, this type of decision-making is regarded as a decision-making under ambiguity Bechara and Martin, On the other hand, when the outcome probabilities of winning or losing are explicit, this type of decision is commonly referred to as a decision under risk Brand et al. In the CGT task, a row of 10 red and blue boxes are presented to the participants. Under instruction, participants would decide and bet on whether a token has been hidden under a red or blue box.
Actually, outcome probabilities of winning or losing associated with specific ratio of red to blue boxes in each trial. Recently, Sutherland and Fishbein observed that higher levels of psychopathy indicate make more risky selections in CGT.
In the GDT, participants are asked to guess a number or combination of numbers two, three, or four numbers before rolling a dice. Each choice is associated with specific fictive gains and losses. Neuroimaging study found that medial orbitofrontal cortex, ventral and dorsal striatum are activated in during GDT decision-making Wilbertz et al. According to our best knowledge, there is no research to investigate the relationship between GDT performance and psychopathy. Svaldi et al. As we have discussed above, most current studies have examined psychopathy and decision-making under uncertainly by IGT, with little attention paid to decision under risk.
Therefore, it is necessary to investigate whether or not different factors of psychopathy relate to decision-making under ambiguity and risk Hughes et al. Intelligence and Decision-Making The research on the intelligence and decision-making adds to the evidence that intelligence is a factor that may influence decision-making.
For example, Deakin et al. Recently, a longitudinal study suggested intelligence positively predicted IGT performance and was a significant predictor for risk, but not ambiguity in adolescent Almy et al. Moreover, IGT performance is also correlated with intelligence in both psychopathic individuals and cocaine-dependent patients Monterosso et al. However, inconsistent results have emerged in two studies that intelligence is not associated with IGT performance in psychopathy individual Blair et al.
Taking the above studies together, it is still uncertain whether intelligence is related to decision-making or as a factor to explain these inconsistent findings from psychopathy and decision-making. The Current Study There are two purposes in the current study: 1 to investigate the relationship between psychopathic factors and decision-making by different tasks and 2 to examine whether intelligence is related to decision-making, or as a moderator variable in psychopathy and decision-making.
We predicted that there is no relation between psychopathy and IGT performance based on prior studies in male offenders Schmitt et al. Prior literature suggests that psychopathy trait is associated with risky selections in CGT Sutherland and Fishbein, In terms of specific psychopathy factors or facet, research have found factor 2 or antisocial facet is associated with risky decision-making Beszterczey et al. As such, we anticipated that antisocial factor of psychopathy would be associated with GDT performance.
It is still unclear whether intelligence would be associated with GDT performance in offenders or psychopathic individuals. Materials and Methods Participants Sixty-five male adult offenders from a domestic prison were volunteered for this study. Five participants were excluded from the final analysis, three participants were removed due to their continuous selection of the same deck in the IGT task and other two participants due to select the same answer in LSRP more than 10 consecutive times.
The average age of participants was Their offenses included drug trafficking Using G-Power version 3. All participants did not receive material or monetary rewards in the current study. Instead they can get educational reform scores by taking psychological tests or lectures, and they will get the corresponding educational reform scores based on the performance.
Description of demographic data of sample. All participants gave their written informed consent prior to the present study. This study has been approved and performed in accordance with the guidelines for ethics committees at both Nanchang Prison and Jiangxi Normal University. Consistent with the design of the classic IGT, the task involves making selections five blocks of 20 selections from four decks of cards A, B, C, and D.
Decks C and D are advantageous: lower reward an average gain of 50 point for each win but lower future losses. At beginning of the task, we will give a loan of point. In each trial of the task, participants will first see a point of fixation with a duration of ms, and then choose one card from four decks of card, which would result in win or loss. Participants see the updated total scores cumulative points for ms on the screen after each choice see Figure 1.
If participants could not understand the task, we will add another five choices for practice. The results of the practice are not a part of final results. The participants were instructed to earn more and more points. The GDT is a decision-making task that explicitly provides information about the rules for winning and losing associated with a given choice. At the beginning of the task, we will give a loan of point and have to play 32 trials. The GDT was required to throw a single virtual dice, and the four options represent the number of dice combinations for participants to bet on.
Before beginning, participants are explicitly informed about the rules for winning and losing, and that amount of point is associated with each of the options chosen.
The results of the practice are not included in the final results. The participants were instructed to win as much point as possible. A three-factor structure of LSRP using 19 of the original 26 items contains three subscales, Egocentricity, Callousness, and Antisocial.
The Egocentricity scale is comprised of 10 items, the Callousness 4 items, and Antisocial 5 items. However, Clark and Watson have argued that reliabilities between 0. Moreover, Clark and Watson have recommended that average inter-item correlations may be a more useful way measuring internal consistency. They have argued that the average inter-item correlations fall in the range of 0.
This test consists 12 items of increasing difficulty. Scores were calculated by summing the number of correct items. Procedure The whole experiment was conducted in two quiet and appropriate temperature rooms and was divided into two parts.
First, participants were requested to complete a battery of self-report questionnaire individually in a room. There was a break of 15 min for rest between the self-report questionnaires and decision-making task.
The whole experiment lasted for 1 h. The two decision-making tasks were presented on the computer using E-Prime2. Statistical Analyses When we analyzed IGT performance, a net score was calculated by subtracting the numbers of disadvantageous choice A and B from the numbers of advantageous choice C and D in each block of 20 cards. The total net score of IGT is the sum of net scores of five blocks.
Regarding the GDT, we calculated a net score by subtracting the number of high-risk choices 1 and 2 from the number of low-risk choices 3 and 4 , such that a higher net score indicates non-risky performance. An alpha level of 0. Statistical analyses were conducted with SPSS The results also showed that Egocentricity, Callousness, and Antisocial were not related to the net score across blocks of IGT task and total net scores.
Lastly, there were no significant correlations between IGT and intelligence. General intelligence was not associated with GDT performance. Moderation Analysis We conducted a series moderation analysis to test whether intelligence moderated the relationships between psychopathy factors and decision-making performance.
In the GDT, the three factors of psychopathy are as independent variable separately, GDT net score as dependent variable and intelligence as moderator variable.
In the second pathway, cognitive representations of the emotions imagining an unpleasant situation "as-if" you were in that particular situation can be activated in the brain without being directly elicited by a sensory stimulus — called the " as-if body loop ".
Thus, the brain can anticipate expected bodily changes, which allows the individual to respond faster to external stimuli without waiting for an event to actually occur. Main article: Iowa gambling task In an effort to produce a simple neuropsychological tool that would assess deficits in emotional processing, decision-making, and social skills of OMPFC- lesioned individuals, Bechara and collaborators created the Iowa gambling task.
Studies using the gambling task have found deficits in various neurological such as amygdala and OMPFC lesions and psychiatric populations such as schizophrenia , mania , and drug abusers. The Iowa gambling task is a computerized test in which participants are presented with four decks of cards from which they repeatedly choose. The participants do not know where the penalty cards are located, and are told to pick cards that will maximize their winnings.
Over the course of a session, most healthy participants come to adopt the profitable low-penalty deck strategy. According to the hypothesis, somatic markers give rise to anticipation of the emotional consequences of a decision being made. Consequently, persons who perform well on the task are thought to be aware of the penalty cards and of the negative emotions associated with drawing such cards, and to realize which deck is less likely to yield a penalty.
Such persons perform less well on the task. The brain regions that were activated during the Iowa gambling task were also the ones hypothesized to be triggered by somatic markers during decision-making. According to the hypothesis, riskier sexual behaviors are more exhilarating and pleasurable, and therefore they are more likely to stimulate repetitive engagement in such behaviors.
The high scorers showed a correlation between the amount of distress they reported having over their HIV status, and their acceptance of risk during sexual behavior — the greater the distress, the greater the risk that these people would take. The low scorers, on the other hand, showed no such correlation. These results were interpreted as indicating that persons with intact decision-making abilities are better able to rely on past emotional experiences when weighing risks, than are persons who are deficient in such abilities, and that acceptance of risk serves to ameliorate emotional distress.
According to the somatic marker hypothesis, such abusers are impaired in their ability to recall and consider past unpleasant experiences when weighing whether to consider drug seeking behaviors.
In response to unpleasant images, drug users showed decreased levels of several neuroendocrine markers, including norepinephrine , cortisol , and adrenocorticotropic hormone.Decks C and D are advantageous: psychopathy reward an average gain of 50 marker for each win but lower future losses. Psychopathy as multi-dimensional construct is somatic to have different hypotheses with decision-making in different dimensions Hughes red al.

The LSRP, which consists 26 items, can be divided into two separate scales: primary and secondary psychopathy. The primary psychopathy was created to assess selfish, manipulative posture toward others, and the secondary psychopathy was designed to assess impulsivity and self-defeating life style Levenson et al.
Correlations only existed between Antisocial and GDT risky decision-making. In general, the results of this study indicate that antisocial factor of psychopathy is more related to cognitive dysfunction which and confirms the previous finding that antisocial factor is a better predictor of decision-making impairments.
The results of the practice are not included in the final results. The PCL-R is a clinical rating scale consisting of 20 items, whose score is based on information collected from prison files and semi-structured interview. According to the hypothesis, riskier sexual behaviors are more exhilarating and pleasurable, and therefore they are more likely to stimulate repetitive engagement in such behaviors. Introduction Psychopathy is a personality developmental disorder that is characterized by a constellation of interpersonally, affective, and behavioral features Cleckley, ; Hare,
According to the hypothesis, riskier sexual behaviors are more exhilarating and pleasurable, and therefore they are more likely to stimulate repetitive engagement in such behaviors.
As we have discussed above, most current studies have examined psychopathy and decision-making under uncertainly by IGT, with little attention paid to decision under risk. The two decision-making tasks were presented on the computer using E-Prime2. Svaldi et al. This led Antonio Damasio to hypothesize that decision-making deficits following vmPFC damage result from the inability to use emotions to help guide future behavior based on past experiences. Previous study has showed that psychopathy is associated with a heightened propensity for violent behavior Hare et al.
Svaldi et al. Regarding the GDT, we calculated a net score by subtracting the number of high-risk choices 1 and 2 from the number of low-risk choices 3 and 4 , such that a higher net score indicates non-risky performance. Their offenses included drug trafficking Using G-Power version 3. The participants were instructed to earn more and more points. In terms of recidivism, individuals with psychopathy are approximately three times more likely to reoffend than non-psychopaths Hemphill et al.
In the first pathway, emotion can be evoked by changes in the body that are projected to the brain — called the "body loop". Before beginning, participants are explicitly informed about the rules for winning and losing, and that amount of point is associated with each of the options chosen. Prior research on psychopathy and decision-making suggest that reversal learning is impaired for highly psychopathic individuals Blair, ; Finger et al. According to the hypothesis, two distinct pathways reactivate somatic marker responses.
For example, Deakin et al. As we have discussed above, most current studies have examined psychopathy and decision-making under uncertainly by IGT, with little attention paid to decision under risk. Moreover, Clark and Watson have recommended that average inter-item correlations may be a more useful way measuring internal consistency. Likewise, Mitchell et al.
