联合Simon效应:现状、影响因素与理论解释

联合Simon效应是一种空间刺激–反应相容性效应,它出现在当两个参与者完成Simon任务的互补成分时。该效应被认为是反映自我–他人整合程度的一个有效指标。影响此现象的因素主要包括社会和非社会因素。社会促进理论、共同表征理论、空间反应编码理论和参照编码理论对该效应作出了解释。未来关于联合Simon效应的研究需深入探讨其影响因素以及脑机制,并进一步完善理论解释。     

冲突控制是领域一般性的还是领域特殊性的?

本研究采用整合交叉范式整合了Stroop任务和Simon任务,在双重认知控制的框架下探讨冲突控制是领域一般性的还是领域特殊性的问题。结果发现:序列一致性效应只出现在任务内,不出现于任务间,显示对冲突的反应性控制具有领域特殊性;比例一致性效应不仅出现在同种任务中,而且扩展到不同任务中,显示对冲突的主动性控制具有领域一般性。本研究结果对于理解认知控制的本质和机制具有重要意义。     

越难读意味着学得越好?学习过程中的不流畅效应

教育心理学领域的不流畅效应认为,学习难读材料要比学习易读材料的效果更好。已有研究主要通过操纵学习材料中的文本、画面或声音属性考察知觉流畅性在学习过程中的作用,并发现不流畅材料可能有助于缓解过度自信现象,但不一定能提高学习效果,不流畅效应的稳健性受到质疑。合理难度理论与不流畅理论均认为,知觉不流畅所引发的额外认知负荷促进了学习;相反,认知负荷理论认为这种额外认知负荷会阻碍学习。对现有研究进行元分析,结果表明,知觉不流畅既降低了学习判断的自信心(d=-0.54),也不利于提高学习效果(d=-0.36),一定程度上支持认知负荷理论。未来研究需关注知觉流畅性本身的操纵、界限及系统性评定,并探讨不流畅效应的边界条件等。     

从信任违背到信任修复:道德情绪的作用机制

早期学者已经从认知的角度分析信任违背的原因及修复方式。近年来,情绪对信任修复的影响引起了重点关注,但是情绪在其中的作用机制并未得到解答。当前的研究主要从情绪影响信任的线索依赖效应和离散情绪(内疚、羞愧、愤怒、悲伤等)对信任修复的影响这两个角度着手研究情绪对信任修复的影响。通过文献梳理发现内疚和共情两种道德情绪是影响信任修复最重要的情绪因素:内疚能够促进受信方做出补偿行为,共情能够促进信任方宽恕他人。基于此构建了道德情绪的信任修复模型,并考虑了目标线索和信任方的特质性宽恕的调节作用。同时建议未来的研究进一步探讨其他离散情绪尤其是道德情绪对信任修复的作用,并关注情境与情绪的交互作用。     

Understanding the underlying mechanism of the spacing effect in verbal learning: a case for encoding variability and study-phase retrieval

The spacing effect refers to the mnemonic benefit of spacing repeated study events across time compared to massing (i.e. cramming) repeated study events. Due to the robustness of this finding, substantial research has been devoted to uncovering the spacing effect’s underlying mechanism. Specification of such a mechanism has been guided by consistent findings across methodologies and several experimental manipulations that serve as boundary conditions. Past reviews of the spacing effect literature have generally considered subsets of these factors but never an exhaustive set. Thus, the current review considers more comprehensively six consistent findings in the extant spacing effect literature pertaining to human memory to better discriminate among the previously proposed theories. Review of the literature provides substantial evidence indicating the need for an encoding variability mechanism [e.g. Glenberg, A. M. (1976). Monotonic and nonmonotonic lag effects in paired-associate and recognition memory paradigms. Journal of Verbal Learning and Verbal Behavior, 15, 1–16] in addition to a reminding mechanism [e.g. Benjamin, A. S., &; Tullis, J. G. (2010). What makes distributed practice effective? Cognitive Psychology, 61, 228–247].     

Enactment supports unitisation of action components and enhances the contribution of familiarity to associative recognition

Memory for actions is usually better following subject-performed tasks (SPT) than verbal tasks (VT). We hypothesised that enactment unitises the components of actions such that familiarity can support associative recognition following SPT. To examine this hypothesis, participants studied verb–object pairs in a SPT or VT condition. During testing, they discriminated between intact, recombined and new items and made Remember/Know judgments; additionally, their EEGs were recorded. Associative recognition was better following SPT than VT. Early frontal event-related potentials (ERPs) were graded according to the item status following SPT, but no such effects were found after VT. Similarly, the late parietal ERPs were graded following SPT, whereas these effects were smaller and did not differ between intact and recombined items following VT. We conclude that enactment unitised the action and object so that familiarity could contribute to associative recognition and that recollection became sensitive to the amount of the matching associative information.     

Is more choice always worse? Age differences in the overchoice effect

Current research on the overchoice effect has been mainly conducted from an adult point of view and with adult subjects. This study investigates whether children, adolescents, and seniors suffer the same negative consequences as adults when facing an overabundance of choice. Findings showed that the overchoice effect did not equally extend to all age groups. While adolescents were affected by the phenomenon in a very similar way as adults, children and seniors suffered fewer negative consequences of an overabundance of choice. Theoretical and practical implications are discussed.     

Mechanisms for the object-based negative compatibility effect: voluntary versus involuntary inhibition

This study investigates whether the object-based negative compatibility effect (NCE) originates from involuntary or voluntary inhibition. We hypothesised that both supraliminally presented primes (the prime is a mug with its handle pointing either left or right) and experimental instructions (i.e., ignoring the prime) in previous studies might induce participants to develop a voluntarily inhibitory strategy that is responsible for the object-based NCE. To test this hypothesis, we conducted 3 experiments. Experiment 1 confirmed a suitable paradigm. Experiment 2 altered participants’ strategies by varying the frequency of compatible trials across blocks. The results revealed a significant NCE for the low-frequency condition, which suggested that voluntary strategy might be primarily responsible for the object-based NCE. Experiment 3 combined a free-choice target with an object-based NCE paradigm. The results showed equivalent frequencies and mean response times between the free-choice responses that corresponded to or were opposite from the orientations of the mug handle. Combined with the results of response time quartiles, which revealed NCEs in fast responses (Q1–Q3) but no compatibility effect in slow (Q4) responses, we concluded that the object-based NCE might be primarily based on voluntary inhibition. Moreover, this inhibition might take effect earlier than that of the arrow-based NCE.     

The moderating role of objective and subjective numeracy in attribute framing

Previous research has found that objective numeracy moderates framing effects: People who are less numerate were found to be more susceptible to goal‐framing and attribute‐framing effects than people who are highly numerate. This study examined the possibility that subjective numeracy likewise moderates attribute framing in contexts where participants are presented with percentages of success or failure. The results show that compared with highly numerate participants, less numerate participants were more susceptible to the effect of attribute framing. Interestingly, this moderating effect was revealed only when using objective numeracy measures, and not when subjective numeracy measures were used. Future research is suggested to replicate these findings, to establish the generalizability of numeracy as a moderator of other cognitive biases, and to examine several possible theoretical explanations for the differential moderation of attribute‐framing bias.     

Greater self‐enhancement in Western than Eastern Ukraine,but failure to replicate the Muhammad Ali effect

Based on the cross‐cultural research linking individualism–collectivism and self‐enhancement, this research examines regional pattern of self‐enhancement in Ukraine. Broadly speaking, the western part of Ukraine is mainly Ukrainian speaking and historically oriented towards Europe, whereas Eastern Ukraine is mainly Russian speaking and historically oriented towards the Russian cultural sphere. We found self‐enhancement on a “better than average” task to be higher in a Western Ukrainian sample compared to an Eastern Ukrainian sample, with differences in independent self‐construals supporting assumed regional variation in individualism. However, the Muhammad Ali effect, the finding that self‐enhancement is greater in the domain of morality than intelligence, was not replicated. The discussion focuses on the specific sources of this regional difference in self‐enhancement, and reasons for why the Muhammad Ali effect was not found.
