科学技术的发展推动以大语言模型为代表的人工智能领域取得了重大突破,大语言模型优势与风险并存,其展现了在临床医学领域巨大的可能性。新的医疗技术的引入可以极大地提升工作效率,同时也带来一定的道德伦理及法律风险。为应对大语言模型产生的不利影响,需要加快立法进程,制定明确的使用规范和监管机制,在技术迭代的同时完善立法及规范。期望大语言模型未来在临床医学的应用方面能够助力我国卫生健康事业的发展。

通过采用老年人一般情况问卷、SF-8生命质量量表和社会支持量表对农村维吾尔族老年人进行入户面对面问卷询问调查。调查结果显示,农村维吾尔族老年人的生命质量受到老年人自身的社会支持和家庭婚姻状况的影响,无论是老年人的社会支持各维度得分还是社会支持总分,均与生命质量的生理健康总评维度得分、心理健康总评维度得分和生命质量总分呈正相关(r=0.113~0.306,P<0.05),且不同家庭婚姻状况的老年人之间的生命质量总分差异具有统计学意义(P<0.05)。 相似文献

The Step it UP! Game is an interdependent group reinforcement contingency based on the Good Behavior Game. We evaluated the effects of the Step it UP! Game on the number of steps taken by 3rd-grade students during physical-education (PE) classes at a local public elementary school. We divided the class into 2 teams and awarded a “Step it UP! Champ” badge to the members of the team with the highest mean step totals at the end of each game. We used a reversal design to compare the mean number of steps taken while playing the game and during regular PE classes. Overall, participants took more steps while playing the game than they did during class periods without the game. When given the opportunity to choose playing the Step it UP! Game or having regular PE class during a follow-up session, 16 of 18 participants voted to play the game. 相似文献

ObjectiveWhen we perform dual-tasks in daily life, task performance is generally reduced. As these reductions in performance (i.e., dual-task interference) are responsible for various accidents such as falls, the repeated practice of dual-task (i.e., dual-task training) is often implemented to reduce dual-task interference. However, the risk of various accidents increases with longer dual-task training, as dual-task interference cannot be avoided. Therefore, it is important to achieve training goals more rapidly during dual-task training. This study sought to determine whether a combination of dual-task training and cognitive tasks would accelerate training effects.DesignThe experimental design included four groups: 1) cognitive task training group, 2) dual-task training group, 3) cognitive task and dual-task training group, and 4) non training group.MethodWe assessed single- and dual-task performance before and after the 2-week training sessions. We adopted a dual-task involving knee extension and an auditory reaction, and used N-back task as a cognitive task. On the other hand, dual-task training was the same method to assess dual-task performance.ResultDual-task interference was reduced in all groups in both the tasks. However, the number of participants in the cognitive task and dual-task training group who achieved a reduction in dual-task cost was significantly higher than those in other groups.ConclusionThese findings could contribute to the development of an effective method for reducing dual-task interference and resolving issues caused by dual-task interference in daily life. 相似文献

This research aimed to investigate the changes in judgment accuracy, confidence, control thresholds, and decision outcomes when people act in two-person groups (dyads) compared with acting individually. First, we used interacting dyads to determine the metacognitive and behavioral outcomes of collective decision making and compared them with those of individuals. Second, we examined whether these changes were related to the trait-confidence and bias of individuals working together. Using a within-person design, undergraduate psychology students (N = 116) completed a General-knowledge Test individually, then together as a dyad. Each question was accompanied by a confidence rating and a decision to bet $10 on the answer. Dyads had significantly higher confidence and lower control thresholds than individuals. They were also significantly more decisive (made more bets) and reckless (lost a higher rate of bets) than when working alone. Thus, we observed a higher rate of decision errors for groups than individuals. The results also demonstrated the important role of individual differences: Overconfident individuals became even more confident, decisive, and reckless when working together compared with less confident or underconfident individuals working together. These findings have important theoretical and applied implications for collective decision making; metacognitive bias and potentially control thresholds may be targeted to alleviate the larger error rates and guide the formation of more effective groups. 相似文献

Is morality biologically altruistic? Does it imply a disadvantage in the struggle for existence? A positive answer puts morality at odds with natural selection, unless natural selection operates at the level of groups. In this case, a trait that is good for groups though bad (reproductively) for individuals can evolve. Sociobiologists reject group selection and have adopted one of two horns of a dilemma. Either morality is based on an egoistic calculus, compatible with natural selection; or morality continues tied to psychological and biological altruism but not as a product of natural selection. The dilemma denies a third possibility—that psychological altruism evolves as a biologically selfish trait. I discuss the classical treatments of the paradox by Charles Darwin ([1871] 1989) and Robert Trivers (1971), focusing on the role they attribute to social emotions. The upshot is that both Darwin and Trivers sketch a natural‐selection process relying on innate emotional mechanisms that render morality adaptive for individuals as well as for groups. I give additional reasons for viewing it as a form of natural, instead of only cultural, selection. 相似文献

Abstract: The present study investigated the social conditions required for minority members to preserve their attitudinal and behavioral consistency in an intergroup context. In the experiment, intergroup belief crosses wherein a belief minority (or majority) in a categorical in‐group was reversed as a majority (or minority) in an out‐group were manipulated. It was hypothesized that individuals supported by the majority in the categorical in‐group would preserve their attitudes and behavioral intentions even though they were a minority in the categorical out‐group. The results supported the hypothesis. Specifically, members of a majority in the categorical in‐group had more consistent behavioral intentions and less attitude changes although they were located as a minority in the out‐group. In contrast, members of a minority within the in‐group preserved consistency on the basis of support from the majority in the out‐group. The theoretical implications of these results are discussed with reference to future research. 相似文献
