休息对自我损耗的补偿作用

两个实验旨在检验自我损耗效应并探讨休息对自我损耗的补偿作用。在实验1中,损耗组被试通过观看注意控制视频诱发自我控制资源的损耗,然后完成Stroop任务。实验2与实验1的不同之处在于,诱发自我损耗后进行不同时间（5分钟、10分钟）的休息处理。两个实验结果发现：（1）注意控制视频成功诱发了自我损耗效应;（2）休息对自我损耗具有补偿作用;（3）在损耗状态下,休息5分钟即对自我控制资源具有补偿作用。研究结果证实了自我损耗的资源枯竭观。     

自控损耗忽略的内容:自我控制的启动效应

大量研究采用双不相关自我控制任务的范式,证明自我控制会引起自我损耗。但双不相关自我控制任务不具有现实普适性,基于生态学考虑探讨自我控制的启动效应。采用两个单因素被试间实验设计,实验1为单自我控制任务下趋向型控制对印象判断的启动效应,实验2为双任务范式下相关控制任务对颜色Stroop任务的启动效应。结果发现:(1)对于单自我控制任务,趋向型控制具有启动效应,抑制型控制具有逆效应;(2)对于双自我控制任务,相关控制任务相对于无关控制任务表现出启动效应。因此,自我控制不等于自我损耗,应关注自我控制的积极效应。     

情绪启动：一次阈上与阈下启动研究的实验报告

本文将情绪图片作为启动刺激,分别以阈上和阈下的方式呈现,采用主观情绪自我评定量表和投射问卷检验情绪启动效应.结果发现阈上情绪诱发以消极情绪明显且宜以自我评定方法检验,而阈下情绪启动积极情绪效应优于消极情绪启动且宜用投射检验.     

金钱概念激活与金钱功能偏好对自我损耗后利他的影响

金钱启动能够提高自我损耗后个体的利他,而金钱功能也可能对损耗后个体利他产生不可忽视的影响。实验让处于自我损耗状态的被试数金钱或白纸,然后测量其利他水平及其对金钱功能的内隐偏好。结果证实了金钱启动的积极效应。此外,在数金钱和数白纸两种条件下,金钱象征性功能偏好对自我损耗后个体利他的效应是相反的。这表明,激活金钱概念与偏好金钱象征性功能都有可能补偿自我损耗后的消极影响,但两者的补偿作用是相互独立的。     

汉语听觉阈下启动效应：来自听觉掩蔽启动范式的证据

使用汉语双字词为实验材料,采用听觉掩蔽启动范式,通过3个实验考察汉语听觉阈下启动效应。结果发现,真词的听觉阈下重复启动效应显著,并且听觉阈下重复启动效应不受启动、目标发音者性别一致性的影响。但真词的阈下语音、语素和语义启动效应及假词的阈下重复和首字启动效应都不显著。这些结果说明,听觉通道阈下呈现的汉语双字词的词汇水平信息可以得到无意识加工。汉语双字词的听觉阈下启动效应可能是基于启动词整词表征的无意识激活。     

自我损耗下积极情绪对亲社会行为的影响

基于自我控制资源理论,本研究通过2个递进实验探究自我损耗下积极情绪对亲社会行为的影响。实验1采用“非利手写作”任务操纵被试的自我损耗,并诱发积极情绪,以被试在独裁者任务中分配的代币数为亲社会行为的衡量指标。结果发现：相比于低损耗组,高损耗组亲社会行为水平更低;诱发积极情绪能够补偿自我控制资源。实验2在此基础上,诱发高、低趋近动机积极情绪,考察自我损耗状态下不同强度趋近动机积极情绪对亲社会行为的影响。结果表明,低趋近动机积极情绪能缓解自我损耗后效。本研究证实了提高自我损耗将降低个体亲社会行为水平,诱发低趋近动机积极情绪可以缓解该效应。     

名字启动对女性容貌吸引力的影响

本研究采用阈上启动和阈下启动两种方式考察名字对女性容貌吸引力的影响。结果发现,阈上启动时名字启动主效应不显著,启动条件与照片类型存在交互作用;阈下启动时名字启动主效应显著,高吸引力名字启动时照片评定比低吸引力名字启动时要高,但是启动条件与照片类型交互作用不显著。本研究在无意识层面支持了名字会影响对容貌吸引力的评定的假设。     

自我损耗的视听通道效应

采用双任务实验范式,通过两个实验探讨了自我损耗的通道效应。实验1考察了完成视听工作记忆任务对执行手柄任务（非视听任务）的影响,结果发现,完成视觉损耗任务导致手柄任务的成绩显著地变差,完成听觉损耗任务、视听非损耗任务均对手柄任务的成绩没有影响。实验2考察了完成视听工作记忆任务对执行Stroop任务（视觉任务）的影响,结果发现,完成视觉损耗任务导致Stroop任务的成绩显著地变差,完成听觉损耗任务、视听非损耗任务对Stroop任务的成绩没有影响。研究结果表明同一自我控制任务通过视听通道完成对随后另一自我控制任务的影响不同,证实了自我损耗的视听通道效应。     

序列语义的类别一致性关系能否进行无意识整合？

阈下语义之间能否进行整合,最近的研究给出了不同的结果。当多个阈下语义词语同时呈现时显示出无意识语义整合效应,但是当序列呈现时没有观察到无意识整合效应。本研究在保留同时呈现方法优点（不同空间呈现位置）的情况下研究了序列呈现的不同汉字词语之间能否产生无意识语义类别关系整合。在实验1中,两个相同或不同类别的词语作为阈下启动刺激先后在两侧呈现,且第一个词语消失后第二词语马上出现,结果显示出无意识语义类别整合效应。实验2延长了两个阈下启动词语之间的时间间隔,结果未发现无意识语义类别整合效应。另外,实验3进一步排除了实验1中第一个启动词语的视觉残留,结果也未观察到显著的无意识语义类别整合效应,说明实验1中观察到的无意识整合效应是视觉残留所致。综合三个实验结果表明,两个阈下词语之间的语义类别一致性关系只有在同时呈现这种特殊条件下才能进行无意识整合加工,说明了短时间维度对于无意识语义关系整合的重要性。

Subliminal speech perception and auditory streaming

Current theories of consciousness assume a qualitative dissociation between conscious and unconscious processing: while subliminal stimuli only elicit a transient activity, supraliminal stimuli have long-lasting influences. Nevertheless, the existence of this qualitative distinction remains controversial, as past studies confounded awareness and stimulus strength (energy, duration). Here, we used a masked speech priming method in conjunction with a submillisecond interaural delay manipulation to contrast subliminal and supraliminal processing at constant prime, mask and target strength. This delay induced a perceptual streaming effect, with the prime popping out in the supraliminal condition. By manipulating the prime-target interval (ISI), we show a qualitatively distinct profile of priming longevity as a function of prime awareness. While subliminal priming disappeared after half a second, supraliminal priming was independent of ISI. This shows that the distinction between conscious and unconscious processing depends on high-level perceptual streaming factors rather than low-level features (energy, duration).     

社会排斥对自我损耗的影响:自我觉知的克服作用

实验1采用打破习惯范式任务和单词搜索任务考察自我觉知对自我损耗的克服作用。实验2采用社会排斥情境任务考察自我觉知在社会排斥中对自我损耗的影响。结果发现:(1)在自我损耗条件下,自我觉知启动组被试Stroop任务成绩显著好于无启动组;(2)在社会排斥情境下,接受组和控制组被试Stroop任务成绩显著好于排斥组。在自我觉知启动条件下,排斥组、接受组和控制组被试的Stroop任务成绩无显著差异。结果证实了自我觉知在社会排斥中对自我损耗的克服作用。     

The modality effect of ego depletion: Auditory task modality reduces ego depletion

An initial act of self‐control that impairs subsequent acts of self‐control is called ego depletion. The ego depletion phenomenon has been observed consistently. The modality effect refers to the effect of the presentation modality on the processing of stimuli. The modality effect was also robustly found in a large body of research. However, no study to date has examined the modality effects of ego depletion. This issue was addressed in the current study. In Experiment 1, after all participants completed a handgrip task, one group's participants completed a visual attention regulation task and the other group's participants completed an auditory attention regulation task, and then all participants again completed a handgrip task. The ego depletion phenomenon was observed in both the visual and the auditory attention regulation task. Moreover, participants who completed the visual task performed worse on the handgrip task than participants who completed the auditory task, which indicated that there was high ego depletion in the visual task condition. In Experiment 2, participants completed an initial task that either did or did not deplete self‐control resources, and then they completed a second visual or auditory attention control task. The results indicated that depleted participants performed better on the auditory attention control task than the visual attention control task. These findings suggest that altering task modality may reduce ego depletion.     

非自主闯入焦虑发生的机制：阈下启动效应的实验研究

本研究采用阈下情感启动范式, 研究威胁信息启动效应及其特质焦虑的调节作用,旨在揭示焦虑非自主闯入性特点形成的机制。实验在随机的三种条件下（阈上/阈下/基线）给38名被试呈现两种目标词（威胁词和中性词）,其中基线条件不呈现目标词;之后要求被试在回避目标词的条件下完成组词任务,结果：（1）无论是中性词还是威胁词,被试阈下条件下目标词的击中率显著高于基线条件;（2）特质焦虑对阈下启动效应起着调节作用：高焦虑组被试威胁词的启动效应显著高于中性词,低焦虑组被试中性词的启动效应显著高于威胁词。结论：阈下启动效应显著,高特质焦虑组个体对威胁信息的无意识加工会增强对威胁信息的意识加工,产生闯入性想法,导致焦虑非自主闯入性的特点。     

The nonconscious road to perceptions of performance: Achievement priming augments outcome expectancies and experienced self-agency

Three experiments explored the effects of priming the achievement concept on the expectation of performance outcomes and experiences of self-agency over outcomes in a task in which performance outcomes were dependent on chance. Experiment 1 and 2 showed that achievement priming produced expectations of higher (more successful) outcomes prior to working on the task, regardless of whether priming was subliminal (nonconscious) or supraliminal (conscious) and that this effect could not be attributed to subjective motivation to perform well. Experiment 3 revealed that subliminal achievement priming decreased participants’ experienced self-agency when outcome feedback was low, but increased self-agency when it was high. Together, these results suggest that activating achievement concepts outside of awareness spontaneously triggers expectations of higher task outcomes, which increases or decreases self-agency depending on whether there is a match or mismatch with observed outcomes. Implications for the literature on achievement-priming effects on behavior are discussed.

利用无意识目标启动降低个体的冲动购买行为：个体目标状态的调节作用

冲动购买会给个体和社会带来诸多不良影响,而探讨如何降低冲动购买的研究报道却很少。此外,仅有的少数研究都是从提升自我控制能力的角度来开展,其干预方法具有一定的局限性。本研究从提升自我控制的动机角度出发,考察利用无意识目标启动能否降低冲动购买,并考察其适用条件。研究发现,无意识目标启动可以显著降低有省钱目标个体的冲动购买行为,而对无省钱目标个体的冲动购买行为没有显著影响。本研究结果提示,无意识目标启动有希望成为一种简单、便捷的降低冲动购买行为的有效干预方式,特别是对有省钱目标的个体而言。     

In the face of emotions: event-related potentials in supraliminal and subliminal facial expression recognition

Is facial expression recognition marked by specific event-related potentials (ERPs) effects? Are conscious and unconscious elaborations of emotional facial stimuli qualitatively different processes? In Experiment 1, ERPs elicited by supraliminal stimuli were recorded when 21 participants viewed emotional facial expressions of four emotions and a neutral stimulus. Two ERP components (N2 and P3) were analyzed for their peak amplitude and latency measures. First, emotional face-specificity was observed for the negative deflection N2, whereas P3 was not affected by the content of the stimulus (emotional or neutral). A more posterior distribution of ERPs was found for N2. Moreover, a lateralization effect was revealed for negative (right lateralization) and positive (left lateralization) facial expressions. In Experiment 2 (20 participants), 1-ms subliminal stimulation was carried out. Unaware information processing was revealed to be quite similar to aware information processing for peak amplitude but not for latency. In fact, unconscious stimulation produced a more delayed peak variation than conscious stimulation.
