本研究采用事件相关电位技术(ERP),探究幽默的加工进程及内外向者在加工进程中的差异。研究以笑话为实验材料,要求被试先浏览背景信息和妙句结尾,然后评估先后呈现的文字材料的关系。行为结果:内向者的反应时显著短于外向者。ERP结果:(1)幽默加工过程包括不一致探测阶段、不一致消解阶段和情绪加工阶段。(2)不一致无关的N400波幅显著大于一致不可笑;不一致无关的P600波幅显著小于不一致可笑和一致不可笑;800ms之后不一致可笑引发了比一致不可笑和不一致无关更大的正波幅。(3)内外向者在幽默加工进程上的差异主要体现在幽默加工阶段的早期。与内向者相比,外向者在幽默不一致探测阶段所用的认知资源较少,加工的自动化程度较高。 相似文献

妒忌是指意识到自己缺乏他人更优越的品质、成就或所有物而产生的自卑、敌意和怨恨等混合情绪,妒忌者渴望得到妒忌目标的优势或希望妒忌目标失去优势。作为一种指向他人财富的复杂情绪,善意妒忌和恶意妒忌会引发不同的行为结果,这主要取决于个体对他人财富的认知评估过程。妒忌通常由向上的社会比较而产生,社会事件应得性、主观公平感、核心自我评价等认知都会对妒忌产生影响。本文从社会比较判断、认知加工过程和神经生理功能等角度来分析妒忌的产生过程和认知机制。基于现有不足,未来的研究可以在妒忌情绪的发展特征、妒忌体验的测量方法和妒忌功能的分化等方面进一步完善。 相似文献

The survival processing effect is a recall advantage for information processed in the context of a grassland survival scenario. The current studies build upon previous research suggesting the effect is due to elaborative encoding and functional thinking. In two experiments, participants completed the “alternate uses test” under five conditions: baseline, grassland survival, Ebola survival, moving to a new home and planning a bank heist. Experiment 1 stimuli were everyday objects. Experiment 2 stimuli were functionally ambiguous “mystery” objects. Number of generated uses was highest in the baseline, but the grassland scenario was consistently highest of the schematic conditions. Recall data lend support to the mnemonic superiority of the grassland condition. Results suggest that grassland scenarios place fewer attenuating constraints on divergent thinking. It is suggested that the survival processing effect might be usefully conceptualised as an effect of creatively thinking about object function in response to broadly defined problems. 相似文献

The purpose of the current study was twofold. First, we investigated whether the type of stimulus processing (e.g. levels of processing) influenced preferences for novel objects. Second, we examined whether the influence of levels of processing on preferences was long lasting (e.g. longer than a day/week). Results showed that levels of processing affected preferences whereby more deeply processed stimuli were preferred over those that were shallowly processed. This effect was more robust for stimuli that were presented multiple times. Additionally, this levels of processing effect lasted for up to 6 weeks, suggesting stability in preferences for information that was more deeply processed. We discuss these results in terms of theories predicting the role of stimulus properties and exposure on the development of preferences. 相似文献

We investigated the navigation‐related age effects on learning, proactive interference semantic clustering, recognition hits, and false recognitions in a naturalistic situation using a virtual apartment‐based task. We also examined the neuropsychological correlates (executive functioning [EF] and episodic memory) of navigation‐related age effects on memory. Younger and older adults either actively navigated or passively followed the computer‐guided tour of an apartment. The results indicated that active navigation increased recognition hits compared with passive navigation, but it did not influence other memory measures (learning, proactive interference, and semantic clustering) to a similar extent in either age group. Furthermore, active navigation helped to reduce false recognitions in younger adults but increased those made by older adults. This differential effect of active navigation for younger and older adults was accounted for by EF score. Like for the subject‐performed task effects, the effects from the navigation manipulation were well accounted for by item‐specific/relational processing distinction, and they were also consistent with a source monitoring deficit in older adults. 相似文献

异族效应(other-race effect) 是一种在面孔加工研究领域中被研究者广为熟之的一种社会性知觉现象。具体而言,就是指个体识别异族面孔的成绩显著低于本族面孔。大量的研究证据表明个体在知觉他人的情绪面孔时,会表现出明显的异族面孔效应。但就目前而言,研究者还不了解自上而下的情绪预期(top-down emotional prediction) 是如何影响面孔识别过程中的异族效应。本研究采用线索-目标范式(cue-target)对该问题进行了考察,实验通过操纵“一致试次”的比率,来区分预期 (75% 的“一致”实验试次) 与非预期实验条件 (50% 的“一致”实验试次)。本实验招募28名健康的大学生被试(12名女性,16名男性)参加正式实验,这些被试无精神疾病、情绪障碍、视力缺陷等疾病。实验后,每一名被试都获得一定的实验报酬。实验结果发现,在正性和负性情绪不预期条件下,个体表现出了对异族面孔的识别劣势,即个体识别异族面孔表情的反应时更长。虽然在负性情绪预期条件下,个体仍然表现出了对异族面孔的识别劣势,但在正性情绪预期条件下,个体对异族面孔的这种识别劣势却消失。这些研究结果表明先前的正性面孔情绪预期有效地消除了异族效应。因此,可以认为自上而下的情绪预期可能是一种促进劣势知觉加工的认知管理策略。 相似文献

In everyday life, people often experience involuntary thoughts about their personal past and future events in response to incidental cues in the environment. Yet, despite the abundance of such cues, our consciousness is not constantly flooded by these involuntary autobiographical memories (IAMs) and involuntary future thoughts (IFTs). The main goal of the present study was to further investigate the possibility that cognitive inhibitory control keeps these involuntary cognitions at bay. To test this inhibition hypothesis, we conducted a large-scale study (n = 157) in which groups of participants with different levels of inhibitory control (low, medium, high) and individuals with ADHD spectrum symptoms were engaged in a laboratory vigilance task in which the frequency of IFTs and IAMs was assessed. Contrary to predictions, although participants across groups differed significantly in terms of their individual inhibitory control capacity, the number of IFTs and IAMs reported during the vigilance task was comparable. In addition, individuals with the ADHD spectrum symptoms did not report more spontaneous thoughts compared to other groups. Together, these findings lend little support for the idea that inhibition is a key mechanism that regulates the occurrence of IAMs and IFTs in everyday life. Other possible mechanisms and avenues for future research are discussed. 相似文献

Of the many vulnerable groups affected by the spread of COVID-19, veterans have been especially impacted by the pandemic. Beginning in March 2020, nationwide shelter-in-place orders rapidly led to widespread job loss and economic upheaval; disruption and breakdown of multiple support systems; and increases in family stress, all of which may exacerbate underlying PTSD symptoms. Although telehealth has proven an effective means of delivering evidence-based psychotherapies for PTSD, little is known about the delivery of these treatments in an intensive, daily format over telehealth. There is growing need for intensive treatment options to reduce treatment-interfering barriers such as high dropout rates. In order to address this gap in the literature, this paper details several design considerations as well as patient selection procedures for a 2-week virtual intensive treatment program (vITP) for veterans with posttraumatic stress disorder (PTSD), consisting of daily individual Cognitive Processing Therapy (CPT) and other adjunctive interventions. We also describe two cases of veterans who successfully completed the vITP including their clinical outcomes, therapist reflections on the process, feedback regarding the program, as well as challenges patients encountered with the telehealth platform. Intensive evidence-based psychotherapy for PTSD delivered through a virtual format seems to show promise, but more systemic research is needed. 相似文献

Anticipation in road traffic enables safer and more comfortable driving. Anticipatory driving is achieved through effective retrieval of prior driving-relevant knowledge using mental models and appropriate cues. Knowing when and which retrieval cues have a critical impact on the anticipation process and how information compatibility affects anticipation can be the basis for supporting people in anticipating and appropriate behavior in road traffic.For generating in-depth insights into the processing of retrieval cues, a video-based experimental study was conducted combining specific compatible and incompatible retrieval cues in urban driving scenarios. From a driver's perspective, participants were asked to anticipate in a two-step approach (measuring low and high certainty anticipation) whether a vehicle ahead would enter their lane or turn onto another street due to a lane blockage ahead. Further, they choose their preferred behavioral intention (accelerate, decelerate or maintain speed). In general, drivers strived for coherent situation representation, and in this process, multiple retrieval cues influenced anticipation in different ways. Participants were more likely to be consistent in their anticipation response. That is, they tend to follow their first intention (equivalent low and high certainty anticipation for either lane change or turn) even in the presence of incompatible stimuli. Inconsistent compared to consistent anticipation responses, however, led to reduced subjective confidence, and in part to increased criticality. Not only anticipation but also intended behavior was influenced by retrieval cues. In accordance, the anticipation of others' behaviors can be considered a predictor of specific intended behavior in road traffic. 相似文献

Driver support features (DSF) have the potential to improve safety, but they also change the driver-vehicle relationship —as well as their respective roles and responsibilities. To maximize safety, it is important to understand how drivers’ knowledge and understanding of these technologies—referred to as drivers’ mental models—impact performance and safety. This simulator study examined how drivers with different mental models of adaptive cruise control performed in edge cases. The study compared the responses of groups of drivers, with strong and weak mental models of ACC, established through a combination of screening, training, and exposure, in edge case situations in a high-fidelity driving simulator. In general, participants with strong mental models were faster than those with weak mental models to respond in edge-case situations—defined as cases where the ACC did not detect an approaching object, such as a slow-moving motorcycle. The performance deficits observed for drivers with weak mental models appear to reflect uncertainty surrounding how ACC will behave in edge cases. 相似文献
