Information about foregone rewards impedes dynamic decision-making in older adults

“Making an informed decision” implies that more information leads to better decisions, yet it may be the case that additional information biases decisions in a systematic and sometimes detrimental manner. In the present study, we examined the effect of additional information on older adults’ decision-making using a task for which available rewards were dependent on the participant’s recent pattern of choices. The optimal strategy was to forego the immediately rewarding option in favor of the option that yielded larger delayed reward. We found that providing information about true foregone rewards – the reward that would have been received had the participant chosen the other option – significantly reduced older adults’ decision-making performance. However, false foregone rewards – foregone rewards manufactured to make the long-term option appear more immediately rewarding – led older adults to perform at a level equal to younger adults. We conclude that providing information about foregone rewards biases older adults toward immediate rewards at a greater rate than younger adults, leading to poorer older adult performance when immediate rewards and long-term rewards conflict, but intact performance when immediate rewards and long-term rewards appear to align.     

自我肯定方式降低高威胁后的消极情绪

通过两个研究考察肯定内部核心品质和肯定外部成就两种不同自我肯定方式对威胁后个体的影响。研究1发现,无论高威胁还是低威胁情境下,选择内部自我肯定的被试均显著多于选择外部自我肯定的被试。研究2发现,内部自我肯定能够在边缘显著水平上降低高威胁感知被试的自我消极情绪,并能够显著降低高威胁感知被试的一般消极情绪,而外部自我肯定不能达到相似效果。上述结果表明,无论在高威胁还是低威胁情境下,个体都更倾向于选择内部自我肯定;与外部自我肯定相比,内部自我肯定对降低个体高威胁情境下的消极情绪有积极作用。     

初中生偶像崇拜及其与生活目标和主观幸福感的关系:性别的调节作用

本研究以3587名初中生为对象,采用问卷测量法,考察了初中生偶像崇拜在性别和年级上的差异,及其与生活目标和主观幸福感的关系,并探究了性别在其中的调节作用。研究发现：（1）女生的偶像崇拜水平显著高于男生的,且偶像崇拜高水平组中女生人数显著多于男生,偶像崇拜低水平组中则相反;初一与初二年级间偶像崇拜的水平及在不同水平上的人数分布均无显著差异。（2）外在生活目标能够正向预测初中生的偶像崇拜水平,其中性别起调节作用,外在生活目标对女生偶像崇拜水平的影响大于男生。（3）性别对偶像崇拜影响初中生主观幸福感上也具有调节作用,即偶像崇拜水平负向预测初中女生的主观幸福感,对男生的主观幸福感则影响不显著。     

Consequentialist Teleology and the Valuation of States of Affairs

Elizabeth Anderson claims that states of affairs are merely extrinsically valuable, since we value them only in virtue of the intrinsically valuable (e.g.) persons in those states of affairs. Since it considers states of affairs to be the sole bearers of intrinsic value, Anderson argues that consequentialism is incoherent because it attempts to globally maximize extrinsic value. I respond to this objection by distinguishing between two forms of consequentialist teleology and arguing that Anderson's claim is either harmless or her argument for the claim is uncompelling. On the first conception of teleology, consequentialists need not hold that states of affairs are the sole bearers of intrinsic value, which allows them to deflect this criticism. On the second account of teleology, even assuming that states of affairs are the sole bearers of intrinsic value, Anderson's argument does not necessarily defeat such views.     

The big carrot: High‐stakes incentives revisited

Using an international dataset of about 35 000 subjects, this paper provides an empirical example of high‐stakes incentives in relation to religious practice. First, we show that incentives (based on absolute belief) play a salient role in religious performance. Second, we find that when both positive (heaven) and negative (hell) incentives are available the former are more effective than the latter. Specifically, it is shown that beliefs in heaven are much more relevant than beliefs in hell when estimating the production of religious commodities (church‐attendance and praying equations).

应当重视肿瘤微环境中外因的研究

长期以来,肿瘤学的几乎所有研究一直在关注肿瘤细胞本身,从哲学角度看这无疑是正确的。肿瘤细胞是肿瘤事件发生发展的内因。近年研究表明,肿瘤的外因,即肿瘤微环境中的非肿瘤细胞及其产物,对肿瘤的发生发展起着十分重要的作用。肿瘤微环境的外因,通过作用于内因选择了更具抵抗性的肿瘤细胞,促进了肿瘤的进展与转移。因此,重视肿瘤微环境的外因研究,对肿瘤治疗学将会开辟以外因为靶点干预的新思路。     

大学生学习动机的测量及其与自我效能感的关系

以270名大学生为被试,对Amabile等人编制的学习动机量表进行修订以确定其对中国被试的适用性,此外还探讨了大学生学习动机与一般自我效能感及领域专门的自我效能感之间的关系。研究结果表明:(1)学习动机量表可以明确区分成用于测量内生和外生动机的两个分量表,前者包括挑战性和热衷性两个维度,后者包括依赖他人评价、选择简单任务、关注人际竞争和追求回报等四个维度。两个分量表的多种信效度指标都十分理想,表明可用于对中国被试的有关研究。(2)男生的内生动机总分显著高于女生,而在外生动机总分上性别差异不显著。具体来看,男女生在挑战性和依赖他人评价两个维度的得分存在显著差异,男生的挑战性高于女生,而女生比男生更依赖他人评价。(3)被试一般的和领域专门的效能感都与内生动机呈正相关,而与外生动机无关。具体来看,效能感与内生和外生动机各维度中的挑战性、热衷性和关注人际竞争呈正相关,与选择简单任务呈负相关。     

内部动机与外部动机的关系

内部动机与外部动机的关系问题在20世纪90年代重新成为动机研究的热点。该文综述了内部动机与外部动机关系的实验研究与理论研究状况。认为实验研究经历了外部动机削弱内部动机、外部动机与内部动机共存、外部动机能够对内部动机产生促进作用三个阶段,研究者的心理学立场是造成分歧结果出现的重要原因;不同的理论模式各有所长,尤其是自我决定理论的新进展“有机辨证元理论”中关于需要的阐述是近期动机研究的亮点,在更高层次上实现了对内部动机与外部动机关系的整合。并提出探讨内部动机与外部动机具体成分之间的关系,检验特质状态与情境状态中二者的相互作用,及心理需要对情境与动机的中介机制应当成为未来研究的方向     

内部动机、外部动机与创造力的关系研究

本研究以277名文科三、四年级的大学生为被试,综合考察在故事、连线和命名任务下,内部动机,外部动机对创造力表现的影响。多变量方差分析发现,对于三个测验的共同部分,内部动机和外部动机的主效应均显著,但交互作用不显著。分别对每个任务进行方差分析发现,对于连线任务而言,内部动机和外部动机的主效应均显著;对于命名任务而言,外部动机的主效应显著,内部动机的主效应不显著;对于故事任务而言,内部动机和外部动机的主效应不显著。内部动机与外部动机之间在三个任务中均不存在显著的交互作用。多重回归分析发现,对于不同的任务,内部动机与外部动机的贡献显著不同。
