临床决策中患者及其家属的地位与作用

医生、医院每天都在为患者做临床决策.而在各个决策中患者与家属应该处于什么地位的问题早有争论.除了疾病外患者性别、年龄、家庭、经济、社会地位的个体差异决定了医生决策的不同.患者要真正参与.就必须真正全面知情.关于患者参与多少的问题要因人而异,可能只是提出意愿,可能提出耗资的底线,可能权衡费效比,可能以生活质量为唯一原则.总之,临床决策中患者及其家属的地位因人而异.     

Positive mood boosts the expression of a dispositional need for closure

Three studies (N=539) examined the hypothesis that positive mood increases the degree to which epistemic motivation, i.e., the need for closure (NFC), affects the way in which an individual processes information (heuristic vs. systematic processing). In each of the studies, different methods of operationalising mood were used: in Study 1, mood was measured as a state; in Study 2, mood was induced by asking participants to recall emotional events; and in Study 3, mood was induced by emotional pictures. The styles of information processing that were utilised by our participants were operationalised in terms of their preferences for (Study 1) and ability to recall (Studies 2 and 3) schema-consistent and schema-inconsistent information. Taken together, the results of the three studies show that only under positive mood, NFC level of an individual is consistent with his or her style of information processing, that is, only under positive mood is there a negative relationship between the NFC level of an individual and the utilisation of schema-inconsistent information. Our results can be explained in terms of the effect that mood has on an individual's perceived ability to achieve NFC.     

Examining the Latent Structure of Posttraumatic Growth Between Male and Female Survivors in the Immediate Aftermath of a Flash Flood Disaster

The study examined and compared the latent structure of posttraumatic growth (PTG) based on three proposed models: 1-factor, 3-factor and 5-factor models in order to (1) find out the factor structure that has the best fit for the Filipino sample; (2) find out the factor structure that best represents PTG in the immediate aftermath of a flash flood disaster; and (3) examine the generalizability of the best-fitted model across gender. A sample of 895 survivor-respondents answered the Posttraumatic Growth Inventory (PTGI) within a month after a deadly flash flood. Based on the best-fitted model, a multi-group comparison between male and female was conducted to determine gender generalizability. Results showed that the 3-factor model comprising of Changes in Self/Positive Life Attitudes, Philosophy of Life, and Relating to Others fitted best in contrast to the other two models. The data also demonstrated the generalizability of the 3-factor model across gender, with invariance in factor loadings, item intercepts, factor variance and covariance, and factor means.     

Bimodal emotion congruency is critical to preverbal infants’ abstract rule learning

Extracting general rules from specific examples is important, as we must face the same challenge displayed in various formats. Previous studies have found that bimodal presentation of grammar‐like rules (e.g. ABA) enhanced 5‐month‐olds’ capacity to acquire a rule that infants failed to learn when the rule was presented with visual presentation of the shapes alone (circle‐triangle‐circle) or auditory presentation of the syllables (la‐ba‐la) alone. However, the mechanisms and constraints for this bimodal learning facilitation are still unknown. In this study, we used audio‐visual relation congruency between bimodal stimulation to disentangle possible facilitation sources. We exposed 8‐ to 10‐month‐old infants to an AAB sequence consisting of visual faces with affective expressions and/or auditory voices conveying emotions. Our results showed that infants were able to distinguish the learned AAB rule from other novel rules under bimodal stimulation when the affects in audio and visual stimuli were congruently paired (Experiments 1A and 2A). Infants failed to acquire the same rule when audio‐visual stimuli were incongruently matched (Experiment 2B) and when only the visual (Experiment 1B) or the audio (Experiment 1C) stimuli were presented. Our results highlight that bimodal facilitation in infant rule learning is not only dependent on better statistical probability and redundant sensory information, but also the relational congruency of audio‐visual information.

Would You Be Happier If You Looked Better? A Focusing Illusion

Some people might believe that individuals who are more satisfied with their body are also happier. However, people tend to overrate the influence of some factors (e.g. money or health) on their happiness; a phenomenon termed the focusing illusion. Our aim was to examine the focusing illusion in relation to body satisfaction. We experimentally manipulated body satisfaction and life satisfaction focus by varying the order of relevant measurement scales. Volunteers (N = 97) completed two questionnaires placed in separate envelopes to control the order of scales administration. Participants either completed the Body Satisfaction Scale followed by the Satisfaction with Life Scale or vice versa. In line with the focusing illusion the association between body satisfaction and life satisfaction was significantly stronger when participants were asked about their body satisfaction first. Body satisfaction as a focusing illusion may need to be considered by scientist as well as lay people who try to look better and be happier.     

个体智力差异的脑电生理学基础 ——来自EEG和ERP的证据

智力的脑电生理学研究近年来蓬勃发展。文章分析了EEG、ERP这两种主要的电生理学技术在智力差异探究中的应用,在智力水平与大脑激活程度的负相关受到任务难度、内容以及被试性别的影响等方面的研究所取得的进展;指出了以往个体智力差异脑电生理学研究中存在的ERP智力差异研究采用的任务略显简单、难以体现智力活动的本质等问题;认为今后利用多种脑电技术结合研究个体智力差异的趋势日趋明显。     

助推戒烟的行为干预策略

烟草危害是人类所面临的重大公共健康挑战之一。传统的控烟策略主要依赖健康宣教、烟草税和控烟条例等手段,但是较少考虑到吸烟行为的“非理性因素”及其心理机制,因此仍不能有效帮助吸烟者成功戒烟。行为科学的发展为助推吸烟者成功戒烟提供了新视角。以实施主体和干预的影响机制为划分标准,可将助推戒烟的行为干预策略分为由政府和公共健康服务部门执行的情境型干预策略和认知型干预策略以及吸烟者可自主执行的情境型和认知型干预策略,一方面便于吸烟者和相关部门选取可执行的戒烟行为干预策略,另一方面为进一步开发和验证助推戒烟的行为干预策略提供参考。虽然基于行为科学的助推干预策略已经取得了一定的进展,未来研究仍有必要进一步在真实世界中验证和评估戒烟助推干预策略的效果。未来也有必要进一步将行为改变技术融入到数字化的戒烟服务或应用小程序中去以提升其效果。未来也需要考察如何应用戒烟助推干预策略防止电子烟产品的负面影响并减少这类策略的误用和滥用。     

认知需求对个体信息加工倾向性的影响

认知需求指"个体参与和享受思考的倾向"。作为一种认知动机,研究者认为其影响了个体信息加工的倾向性。对国外近30年来的相关研究进行回顾,结果显示认知需求主要在努力程度、自主性和结果及其应用范围这三方面影响了个体的信息加工。最后,展望了认知需求的研究趋势,并从认知需求的测量、无关变量的控制、影响的长期性和稳定性,以及情感因素负荷四方面探讨了现有相关研究的不足。
