Summary: This study examines a novel computational cognitive model of the Iowa Gambling Task (IGT) that captures fine-grained differences in decision-making styles in individuals with recent methamphetamine use disorders. The models generated from the study are more sensitive than traditional metrics in detecting risky decision-making behaviors in persons with methamphetamine use disorders. Methamphetamine users exhibit lower estimation of possible losses and associated risk, while multi-substance users show behavior patterns that affect the evaluation of losses and the risk associated with gains.

Summary: Despite the common high risk-taking behaviors in males, studies have shown that males tend to choose safe long-term rewards over risky short-term rewards in the Iowa gambling task. The role of sex and stress hormones in male decision-making in different phases of the task was examined. Hormone fluctuation had phase-specific effects on decision-making, with testosterone improving decision-making in risk trials and cortisol being detrimental in uncertainty trials.

Summary: The study found that facial expression feedback influences learning tasks in a context of ambiguity, with a slower learning rate compared to symbolic feedback. There were no differences in deck selection or computational model parameters between the two conditions, and no correlation was observed between task indicators and the results of depressive questionnaires.

Summary: Through studies using the Iowa Gambling Task, it is found that patients with Parkinson's disease tend to prefer risky choices, possibly due to difficulties in anticipating negative consequences or insensitivity to punishment. Additionally, dopamine medications may have an impact on patients' decision-making under uncertain conditions.

Summary: This study found that patients with adolescent-onset schizophrenia (AOS) exhibit impaired decision-making, particularly under risky conditions, and have difficulties with executive function. This suggests a specific pattern of decision-making deficits in AOS, emphasizing the importance of considering risk-taking behaviors and executive functions in this population.

Summary: Decision making under acute stress is common in daily life. Neuroticism has been found to modulate risky decision-making behaviors, but the neural correlates underlying this association remain unclear.

Summary: This study examined the effects of pairing sounds with outcomes in the BART and found that regardless of the outcome or valence, sounds did not affect risk-taking behavior in an adult, non-clinical sample.

Summary: The study explores the genetic architecture of risky decision-making in psychiatric disorders and its correlation with cannabis use. The results indicate a polygenic nature of risky decision-making and its overlap with cannabis use.

Summary: Oxytocin has been extensively studied for its effects on socio-cognitive and behavioral functions, but limited evidence exists regarding its effects on non-social cognition and decision-making. This study found that intranasal administration of 24 IU oxytocin had detrimental effects on decision-making under low outcome predictability/high ambiguity, leading to riskier performance. In contrast, oxytocin resulted in slightly less risky decisions under high outcome probability/low ambiguity. These findings suggest that oxytocin may influence decision-making in healthy males, depending on contextual information.

Summary: The Iowa Gambling Task (IGT) is used to evaluate emotion-based decision-making ability in clinical populations, including schizophrenia. However, there is a lack of stable behavioral measures in IGT to discriminate decision-making performance between schizophrenic cases and healthy participants. Despite this, individuals with schizophrenia tend to make more choices from disadvantageous deck B in IGT, particularly in the later learning process. The PDB phenomenon is challenging to observe in both schizophrenic and control groups due to the dominant impact of gain-loss frequency on the decision-making process.

Summary: The study demonstrates that chronic exposure to glucocorticoids induces suboptimal decision making in uncertain environments, impairs spatial working memory, and affects motor learning processes. Neurobiological analysis shows that glucocorticoid receptor expression is downregulated in the medial prefrontal cortex of individuals exposed to cortisol, which negatively correlates with their decision making performance.

Summary: Studies show that individuals who have attempted suicide exhibit deficits in decision-making, specifically performing worse under conditions of risk. These impairments in decision-making are independent of age, gender, and psychiatric disorders, indicating they may be considered a cognitive trait of suicidal vulnerability.

Summary: Chronic cannabis users showed impairments in decision making tasks compared to non-users, displaying a preference for immediate rewards, less advantageous decisions, and greater impulsivity. However, both groups had similar performance on the Probabilistic Reversal Learning Task.

Summary: This study aimed to investigate the decision-making deficit in patients with chronic migraine and medication overuse headache (CM + MOH). The results showed that CM + MOH patients made more disadvantageous decisions under ambiguous conditions. This suggests that decision-making may be related to MOH.

Summary: This study aimed to investigate the relationship between schizotypy and language ability, measured by semantic fluency. It found a non-linear relation between schizotypy and semantic infrequency and productivity, indicating atypical semantic activation and processing in individuals with schizotypal traits. Valuable content-based information is missed when only analyzing semantic fluency data via the traditional method in the schizophrenia spectrum population.

Summary: Community colleges and open-access two-year campuses serve as important pathways to higher education, but the success rate of transfer students is low. Internal transfer students are able to overcome barriers related to transfer information more easily due to their extensive social support networks. Utilizing social support and obtaining accurate transfer information can enhance self-efficacy and adjustment among transfer students.

Summary: This study found that during the COVID-19 pandemic, behavioral inhibition and risk-taking propensity were important predictors of involvement in COVID-19-related risk behaviors. Numeracy and risk-taking propensity were associated with involvement in social risk behaviors, while being male, higher risk-taking propensity, and impulsivity were associated with increased health/safety risk behaviors. Younger age, lower risk-taking propensity, and lower impulsivity were associated with a greater likelihood of blood donation. Increasing risk perception was associated with a greater likelihood of registering as an organ donor, but a higher risk-taking propensity was associated with a decreased likelihood of organ donation registration. For flu vaccination, a higher risk-taking propensity was associated with a greater likelihood of getting vaccinated during the flu season.

Summary: This study investigated the effects of music on decision making and other executive functions. It was found that rock music was more distracting than classical music when passively listening, but there were no differences when actively listening. Despite the self-reported increased distraction, there were no significant differences in task performance.

Summary: The Iowa Gambling Task (IGT) is commonly used in clinical and research settings, but there are concerns about the validity of the task due to lower-than-expected performance among healthy adults. This study found that scoring approach impacts interpretation of performance patterns, with participants tending to select decks with lower loss frequency. However, overall participants underperformed compared to normative data, indicating the importance of scoring approach in determining impaired decision making in adults through the IGT.

Summary: The studies found that vulnerable narcissists were more concerned about experiencing physical pain, but did not actually report stronger pain experiences. On the other hand, grandiose narcissists seemed less concerned about physical pain, but were more likely to have worse mood following pain experiences. However, both types of narcissists had different reactions when it came to experiencing social pain.
