注意力资源限制与双任务的相互干扰机制

采用心理不应期研究范式, 两个反应时实验检测了注意力资源分配的特征以及双任务的相互干扰机制。每次实验中, 要求被试快速、相继对高低音辨别任务(T1)和Stroop任务(T2)作出选择性反应, T1和T2间采用6种不同的时间间隔(SOA), 以系统考察不同SOA条件下两个任务的反应时走势。结果发现：(1) 在重叠的双任务情境中, T1的中枢加工导致在T2上出现显著的PRP效应, T2的中枢反应选择对T1的反应选择和反应执行加工同样产生显著的影响。SOA以及T2的难度与复杂度实质性地影响了T1的反应选择和反应执行加工。(2) 当两个任务同时需要进行中枢反应选择加工时, 一个任务占用更多的注意资源将导致另一任务获得较少的注意资源, 注意资源量的多寡直接决定了该任务的加工效率。(3) 两个任务的加工相互影响、相互制约, 这种制约机制不仅仅存在于中枢反应选择阶段, 在反应执行阶段仍然存在。     

多特征刺激在视觉工作记忆中的存储模式

使用事件相关电位技术, 采用变化觉察范式, 以双色块和单色块为刺激材料, 通过两个实验探讨了多特征刺激在视觉工作记忆中的存储模式。实验1通过对双色块和单色块的比较来考察特征数量对视觉工作记忆资源分配的影响, 通过操控双色方块的变化幅度来考察精度需求对资源分配的影响。结果发现, 特征数量的增加诱发了更强的对侧延迟活动(CDA), 而精度需求的提高并没有引起对侧延迟活动上的差异, 却诱发了指示自上而下的控制的晚期正成分(LPC)的增强。实验2通过在测验阶段加入指示可能变化的部分的提示符, 发现提示符并未能促进变化觉察的行为反应。整个研究表明, 特征数量影响视觉工作记忆资源的分配, 而精度需求并不起作用, 同时多特征刺激在视觉工作记忆中的存储单位并不是单个的独立特征, 而是整合的客体。     

Self-reported posttraumatic growth predicts greater subsequent posttraumatic stress amidst war and terrorism

Background and objective: This study tested three alternative explanations for research indicating a positive, but heterogeneous relationship between self-reported posttraumatic growth (PTG) and posttraumatic stress symptoms (PSS): (a) the third-variable hypothesis that the relationship between PTG and PSS is a spurious one driven by positive relationships with resource loss, (b) the growth over time hypothesis that the relationship between PTG and PSS is initially a positive one, but becomes negative over time, and (c) the moderator hypothesis that resource loss moderates the relationship between PTG and PSS such that PTG is associated with lower levels of PSS as loss increases. Design and method: A nationally representative sample (N?=?1622) of Israelis was assessed at three time points during a period of ongoing violence. PTG, resource loss, and the interaction between PTG and loss were examined as lagged predictors of PSS to test the proposed hypotheses. Results: Results were inconsistent with all three hypotheses, showing that PTG positively predicted subsequent PSS when accounting for main and interactive effects of loss. Conclusions: Our results suggest that self-reported PTG is a meaningful but counterintuitive predictor of poorer mental health following trauma.     

The Impact of Time‐Keeping Direction on Compensatory Consumption: The Role of Perceived Resource Deficiency

Time is a scarce resource, and time‐keeping has become a common part of our lives. This research investigates the impact of exposure to a specific direction of time‐keeping on resource deficiency perception and on compensatory consumption of calories. Results from four studies show that exposure to downward time‐keeping (e.g., 60→1 s), compared to upward time‐keeping (e.g., 1→60 s), results in a higher perceived resource deficiency, leading to a higher preference, consumption, and choice of caloric foods. The effect is attenuated for evaluation of calorie‐lean foods, or by recalling instances of resourcefulness, or when time is not a resource (as in the case of waiting). Related alternate explanations are addressed. This research is the first to identify a novel antecedent of resource deficiency (i.e., time‐keeping direction), and to elicit an unexplored aspect of temporal cognition, that exposure to direction of time‐keeping can influence compensatory consumption in an unrelated domain. These findings contribute to the literature on temporal cognition and resource deficiency and may inspire further research in these domains.     

The generalized sense of power is a psychological resource: Evidence from a disaster response field training exercise

We examined whether the generalized sense of power—the belief that one is able to influence others in one's various social relationships—serves as a psychological resource that enables leadership in high-stakes, unfamiliar group challenges, such as emergencies or crises. We studied current and prospective humanitarian aid professionals (N = 180) during a major field training exercise: a three-day, immersive simulated humanitarian crisis. Individuals who entered the simulated crisis with a greater sense of power in their social relationships experienced lower stress (anxiety), behaved more assertively, and left the simulation with a relatively heightened desire to lead, despite not being deemed better leaders by their teammates. Lacking an initial sense of power was associated with experiences (e.g., feeling timid) that undermined the desire to lead. These results suggest that the psychological sense of power is a key leadership resource, without which one may be at risk of self-selecting out of leadership.     

Children and adolescents coordinate group and moral concerns within different goal contexts when allocating resources

Coordinating complex social and moral concerns when allocating resources is a key issue in late childhood and early adolescence. This study explored resource allocation in three goal contexts that required children to focus to differing degrees on moral and group concerns. Children (9–11-years, M^age = 9.84, n = 190) and adolescents (14–16-years, M^age = 14.92, n = 154) were informed their school peer group held an in-group norm (competition, cooperation). Participants allocated resources between their in-group and an outgroup within one of three goal contexts (prosocial, learning-focused, and group-focused). Participants allocated in favour of their in-group to achieve a prosocial goal but attenuated this when the goal was focused on learning and cooperation. Adolescents, more than children, reasoned about the goals of resource allocation to justify their decisions. From 9 years old, children begin to coordinate peer group norms and goal information when deciding how to allocate resources within intergroup contexts.     

童年亲子关系与“好资源”对未婚男性性开放态度的影响

本研究采用实验启动的方式探讨“好资源”和童年环境对未婚男性性开放态度的影响, 结果发现童年亲子关系(而不是童年经济状况)在资源线索启动和性开放态度之间存在显著调节作用。研究1采用想象启动来控制个体的资源获取状况, 结果发现：童年亲子关系差的个体在“好资源”想象时其性开放态度较“差资源”想象时明显提升。研究2采用图片情境的资源想象方式, 在研究1的基础上进一步把亲子关系细分成亲子沟通、亲子焦虑和亲子回避三个维度, 结果表明：童年亲子回避在男性资源状况启动和性开放态度之间存在显著调节作用, 童年亲子高回避的个体在“好资源”照片情境想象下其性开放态度显著提升, 而童年亲子低回避的个体在“好资源”照片情境想象下其性开放态度明显下降; 此外, 童年亲子回避在性开放态度上的主效应显著, 亲子回避程度高的个体其性开放态度也更高。两个研究共同揭示了“男人有钱就变坏”的情境和群体特殊性。     

和谐医患环境与公民健康权的保障

在健康权保障体系中,卫生资源配置的公平与效率的失衡是导致现阶段我国公民健康权不平等的关键。而作为一级经济主体的医疗机构,在促进卫生资源配置和享用的公平性作用上,则是无效率的,因此国家应积极运用法律、政策等外部手段,实现其协调性的复位,以服务于建设和谐医患环境的需要。     

“面子”定义探新

面子研究是中国国民性研究的基础性内容。通过面子现象的要素归纳和面子行为的归因分析,借鉴面子既有定义的合理思想,给出了全新的面子定义。面子是个体藉由行为或社会性资源展现其自我价值,寻求他人的确认且受到意外的认同时,凸现于个体内心的自我价值感与相应体验。面子实质上是个体对自我在他人心中的价值与地位的关注,自我价值是面子的内核,社会性资源是面子的象征。自我价值的认同诉求与回应的冲突即评价冲突是面子产生的直接诱因。个体在交往中表现“相符行为”或允许他人利用自己的社会性资源是赢得面子的基本途径。确认个体价值的“他人取向”是面子现象的社会根源。
