The present study aims to investigate theimpact of different emotions on the decision-making behavior of meth users. We used 2 (gender: male, female) × 3 (emotion:positive, negative, neutral) × 5 (block: 1, 2, 3, 4, 5) mixed experiment design. The study involved 168 meth users who weredivided into three groups: positive emotion, negative emotion and neutral emotion group, and tested by the emotional IowaGambling Task (IGT). The IGT performance of male users exhibited a decreasing trend from Block 1 to Block 3. Female methusers in positive emotion had the best performance in IGT than females in the other two groups. In positive emotion, the IGTperformance of female meth users was significantly better than that of men. Female meth users in positive emotion had betterdecision-making than those in negative or neutral emotion. Female meth users in positive emotion had better decision-makingperformance than males in positive emotion. In negative and neutral emotions, there was no significant gender difference indecision-making.展开更多

Characteristics of aggression were assessed using three self-report questionnaires as well as systematic staff observations, complemented with data from criminal records. A semi-structured interview was conducted to rate lifetime prevalence of TBI and the Iowa Gambling Task (IGT) was completed to assess risky decision-making. Out of the total of 133 participants, 74 (55.6%) reported having sustained one or more incidents with potential TBI. Statistical comparisons between offenders with and without TBI indicated that the offenders with TBI reported significantly higher levels of (reactive) aggression on two out of three questionnaires than offenders without TBI (p-values ranging from 0.003 to 0.008), but no significant differences were found on staff observations of aggression and on the IGT. The higher conviction rates in offenders with TBI compared to the non-TBI group showed a trend. The confirmed relationship between TBI and higher aggressive tendencies is especially relevant for forensic populations due to the high prevalence rates of TBI in offenders. How this relates to specific cognitive processes remains unclear. The lack of a statistical difference between offenders with and without TBI on the IGT is in contrast with literature in non-offender samples, but seems to be in line with other studies in forensic populations.展开更多

Design: Semi-structured interviews were conducted with 10 individuals with experience in surrogate decision-making for an older adult family member. Methods: The recorded interview data were transcribed verbatim, divided into minimum semantic units, and coded. Next, categories and subcategories were abstracted. A comparison was made with the conceptual constructs of a previous study that examined decision-making by families in a life-threatening crisis. Results: Four categories were extracted from 489 antecedents, 370 attributes, and 388 consequences. One new category was abstracted for each of: 1) antecedents: observing abnormalities and responding, while being worried about death;2) attributes: deliberating on the patient prognosis, the relationship with the patient, and what they believe the patient would want;and 3) consequences: continuing support during convalescence. It is desirable to provide support based on the characteristics of families of older adults, including considering the psychological burden on the families who make surrogate decisions, and also the burden of subsequent caregiving because it is not and in the present environment has not been common for patients to express their wishes beforehand.展开更多

This non-experimental descriptive, cross-sectional study was conducted by means of a non probability sampling of type cases. The sample consisted of 325 subjects, to whom the Hungry Donkey Task in its version adapted for Colombia was applied. Through descriptive statistics, the test performance trend was established, finding that participants aged 7 to 11 years had better performance than adolescents 12 to 14 years old, which partially supports the hypothesis of decision-making development in J shape. Subjects aged 15 to 17 years had the most disadvantageous performance, which may indicate immaturity and slow development of prefrontal areas and the influence of the trend towards risk-taking, characteristic of this age range.展开更多
