心理距离与建构水平的双向作用关系

心理距离概念源于时间建构理论,以自我为中心,参照点是此时此地自己的直接经验,并沿不同维度向外扩展,形成通常所认为的时间、空间、社会距离和假设性四个维度。本文述评了心理距离与建构水平的双向作用关系及其产生原因,即远心理距离使人采用核心、去背景化特征表征事物,近心理距离使人采用外围、背景化特征表征事物;反之,高水平建构使人感知到远心理距离,低水平建构使人感知到近心理距离。未来研究应关注非自我参照点的客观距离与建构水平的关系,以及心理距离与建构水平关系的心理物理学研究等。     

时间距离、封面故事和概率对框架效应的影响

研究一以时间距离和封面故事为变量考察对认知相关性的影响, 结果发现时间距离、封面故事及二者间的交互作用显著。坏封面故事中, 人们对1年后发生的事件要比1周、5年与50年后事件的认知相关程度都高, 即最重视; 好封面故事中, 4个时间距离间的认知相关程度差异不显著。研究二在1周、1年、5年和50年四个时间距离下, 探讨封面故事、框架和概率对风险偏好的影响, 结果表明：仅当时间距离为1周时, 不同概率在坏封面故事中风险倾向的差异显著。同时, 大概率下, 封面故事、封面故事与框架的交互作用对风险偏好的影响达到显著水平, 表现出在坏封面故事中, 与负面框架相比, 正面框架下风险回避的比例更高, 符合框架效应。结合研究一、二发现框架效应正发生在认知相关程度最低时。     

心理距离、封面故事对框架效应的影响

该研究旨在比较志愿决策和“亚洲疾病”决策两种任务领域下,人们风险偏好的特征情况,以考察远、近不同社会距离对风险偏好的影响.同时,在传统的坏封面故事下,增设好封面故事情景,以期发现封面故事作为决策前的必要背景信息对人们决策的影响.选取高中生为被试,结果发现：（1）在近的社会距离下决策时,风险偏好受到时间距离、封面故事、概率和框架的影响;在远的社会距离下,这些因素的影响作用不大;（2）志愿决策中,风险偏好仅在小概率条件下,受封面故事、框架等因素的影响;在好封面故事下,风险偏好受到框架的影响;在坏的封面故事下,风险偏好受时间距离和框架的交互作用影响.     

心理距离对大学生职业决策偏好的影响

职业决策对大学生职业生涯发展具有重要意义。心理距离作为个体决策的重要影响因素之一,是否也影响着大学生的职业决策偏好？研究通过4个实验,采用2（心理距离：远、近）*2（性别：男、女）混合实验设计,以大学生为研究对象,探讨了心理距离（空间距离、时间距离、社会距离、假设性）和性别对职业决策偏好的影响。研究发现：(1)大学生在心理距离远的情境下更偏好选择稳定、职业声望高的职业;在心理距离近的情境下更偏好选择薪资高、专业对口的职业。（2）空间距离、时间距离、社会距离近的情境下,男大学生比女大学生更偏好选择薪资高、专业对口的职业。     

心理距离对基线比例忽略的影响

基线比例忽略是指在不确定情境中, 个体进行判断和决策时不能充分利用或者忽略基线比例的现象。本研究通过系列情境实验探索了三种不同维度的心理距离, 即时间距离、空间距离和社会距离对基线比例忽略的影响。结果发现, 三种心理距离均能够对基线比例忽略产生影响：当时间距离、空间距离和社会距离较近时, 个体更容易表现出基线比例忽略现象; 而当时间距离、空间距离和社会距离较远时, 个体的基线比例忽略倾向减弱。     

心理距离对风险决策框架效应的影响

解释水平理论是一种解释心理距离怎样影响个体的思维决策的社会认知理论。研究基于解释水平理论,探查了心理距离对风险决策框架效应的影响。实验从心理距离的四个维度入手,每个维度均采用2（解释水平高、低）×2（正框架、负框架）的被试间设计,用于检验解释水平是否调节框架对被试决策任务的选择。结果表明,当心理距离越远,解释水平越高时,被试产生明显的框架效应;而当心理距离越近,解释水平越低时,框架效应明显减弱。除了大概率情况下的框架效应削弱至不显著,其余维度的高、低解释水平下的框架效应均显著。     

When Good Things Feel Closer and Bad Things Feel Farther: The Role of Perceived Control on Psychological Distance Perception

Prior research has found that people perceive positive objects and locations as physically closer than negative ones. Yet, other work has found the opposite to be true for perceptions of temporal distance, where negative future events feel closer than positive ones. Motivated by this seeming discrepancy, we propose that (a) feelings of control can differentially influence how far away valenced (i.e., positive or negative) targets feel in space and time and that (b) the difference in perceived control over space versus time can account for these opposite findings. First, across four studies, we show that high (vs. low) control makes positive targets feel closer and negative targets feel more distant in both physical space (Studies 1 and 1a) and time (Studies 2 and 2a). Then, in Studies 3 and 4, we simultaneously examine perceptions of spatial and temporal distance and show that baseline differences in perceived control between these domains can explain the prior discrepant findings. Finally, a within‐paper meta‐analysis offers further support to these findings.     

The Physical Appearance Perfectionism Scale: Development and Preliminary Validation

Eight studies with data from 2316 students are presented describing the development and preliminary validation of the Physical Appearance Perfectionism Scale (PAPS), a brief measure with two subscales: Worry About Imperfection and Hope For Perfection. Results from exploratory and confirmatory factor analyses confirmed the measure’s two-dimensional structure. Moreover, correlation analyses provided first evidence for the two subscales’ differential validity: Worry About Imperfection showed negative correlations with positive self-perceptions of one’s appearance (e.g., appearance self-esteem) and positive correlations with maladaptive concerns aspects of perfectionism, physical appearance concerns (e.g., body image disturbances), and body weight control whereas Hope For Perfection showed positive correlations with positive striving aspects of perfectionism, positive self-perceptions, and impression management. In addition, all PAPS scores showed high reliability (Cronbach’s alpha) and temporal stability (test-retest). Overall the findings suggest that the PAPS is a reliable and valid instrument to assess positive and negative aspects of physical appearance perfectionism.     

消费者对犯错品牌评价的时间打折效应及其影响因素

通过研究品牌犯错的时间打折效应,本文试图探讨潜在消费者（未购买者）对犯错品牌评价的心理倾向。实验1研究发现,随着品牌犯错事件时间距离的延伸,消费者对身体性危害-品牌犯错的评价不会改善,即没有出现时间打折效应,而对功能性危害-品牌犯错的评价则逐渐提高,从而表现出时间打折效应。但实验2研究进一步发现,随着品牌犯错事件相关性的增强,功能性危害-品牌犯错的时间打折效应也消失。结论：潜在消费者对犯错品牌评价的心理倾向表现为“消费者防御”,并且身体性危害-品牌犯错启动的消费者防御要强于功能性危害。     

Multifractal roots of suprapostural dexterity

Visually guided postural control emerges in response to task constraints. Task constraints generate physiological fluctuations that foster the exploration of available sensory information at many scales. Temporally correlated fluctuations quantified using fractal and multifractal metrics have been shown to carry perceptual information across the body. The risk of temporally correlated fluctuations is that stable sway appears to depend on a healthy balance of standard deviation (SD): too much or too little SD entails destabilization of posture. This study presses on the visual guidance of posture by prompting participants to quietly stand and fixate at distances within, less than, and beyond comfortable viewing distance. Manipulations of the visual precision demands associated with fixating nearer and farther than comfortable viewing distance reveals an adaptive relationship between SD and temporal correlations in postural fluctuations. Changing the viewing distance of the fixation target shows that increases in temporal correlations and SD predict subsequent reductions in each other. These findings indicate that the balance of SD within stable bounds may depend on a tendency for temporal correlations to self-correct across time. Notably, these relationships became stronger with greater distance from the most comfortable viewing and reaching distance, suggesting that this self-correcting relationship allows the visual layout to press the postural system into a poise for engaging with objects and events. Incorporating multifractal analysis showed that all effects attributable to monofractal evidence were better attributed to multifractal evidence of nonlinear interactions across scales. These results offer a glimpse of how current nonlinear dynamical models of self-correction may play out in biological goal-oriented behavior. We interpret these findings as part of the growing evidence that multifractal nonlinearity is a modeling strategy that resonates strongly with ecological-psychological approaches to perception and action.     

Space and Time in the Child's Mind: Evidence for a Cross-Dimensional Asymmetry

What is the relationship between space and time in the human mind? Studies in adults show an asymmetric relationship between mental representations of these basic dimensions of experience: Representations of time depend on space more than representations of space depend on time. Here we investigated the relationship between space and time in the developing mind. Native Greek‐speaking children watched movies of two animals traveling along parallel paths for different distances or durations and judged the spatial and temporal aspects of these events (e.g., Which animal went for a longer distance, or a longer time?). Results showed a reliable cross‐dimensional asymmetry. For the same stimuli, spatial information influenced temporal judgments more than temporal information influenced spatial judgments. This pattern was robust to variations in the age of the participants and the type of linguistic framing used to elicit responses. This finding demonstrates a continuity between space‐time representations in children and adults, and informs theories of analog magnitude representation.     

Probability of reinforcement and the development of stimulus control

Pigeons were trained with a successive discrimination procedure in which responding during the negative stimulus was never reinforced and responding during the positive stimulus was reinforced according to one of four probability values. This discrimination training followed extensive training with a single, neutral stimulus and the same temporal distribution of reinforcements. The development of stimulus control was studied by tracing the difference in rate of responding between the positive and negative stimuli over the course of discrimination training. Response rate during the positive stimulus remained constant, while that during the negative stimulus decreased to zero. The probability of reinforcement associated with the positive stimulus affected both the total number of responses emitted during the negative stimulus and the number of negative stimulus presentations during which responding occurred. However, the number of reinforcements during the positive stimulus preceding the attainment of various degrees of stimulus control was similar for all probability values.     

Inclusion-exclusion of positive and negative past selves: mood congruence as information

The current research challenges the widespread truism that recalling a positive self necessarily increases self-esteem, whereas recalling a negative self necessarily decreases self-esteem. Four experiments demonstrate that chronically happy people show a relative increase in self-esteem by recalling either a positive or a negative self. Chronically sad people, however, show a relative decrease in self-esteem by recalling either a positive or a negative self. These effects are due to divergent perceptions of mood congruence between the recalled self and the current self. Specifically, happy people perceive high mood congruence between a recalled positive self and the current self but low mood congruence between a recalled negative self and the current self. In contrast, sad people perceive high mood congruence between a recalled negative self and the current self but low mood congruence between a recalled positive self and the current self. Independent of chronic mood, mood congruence leads to perceptions of temporal recency, whereas mood incongruence leads to perceptions of temporal distance. In line with the inclusion-exclusion model of social judgment, perceived temporal recency elicits assimilation effects on self-esteem, whereas perceived temporal distance elicits contrast effects on self-esteem.     

It feels like yesterday: self-esteem,valence of personal past experiences,and judgments of subjective distance

Supporting predictions from temporal self-appraisal theory, participants in 3 studies reported feeling farther from former selves and experiences with unfavorable implications for their current self-view than from equally distant selves and experiences with flattering implications. This distancing bias occurred when assignment to negative and positive pasts was random, for both achievement and social outcomes and for single episodes as well as longer term experiences. Consistent with a motivational interpretation, the distancing bias was stronger among high than low self-esteem participants and occurred for personal but not for acquaintances' past events. Frequency of rehearsal and ease of recall of past episodes also predicted feelings of distance, but these variables did not account for the Self-Esteem x Valence interaction on subjective distancing of personal events.     

时间距离对于验证性信息加工的影响

研究基于解释水平理论考察时间距离对于验证性信息加工的影响, 即在个体和组织决策情境中, 人们倾向于偏好选择和高估与自身观点和决策相一致的信息, 而不是非一致性信息。通过4个情境决策实验, 研究结果一致表明近期决策会提高信息搜寻和评估中的验证偏差, 而远期决策会降低它们的验证偏差, 知觉到的决策确定性在其中起到部分中介作用(实验1b)。解释水平(实验2)和期许性/可行性表征(实验3)分别在时间距离对验证性信息加工的影响中起到调节作用, 结果依次表明在低解释水平(高可行性-低期许性特征)条件下, 时间距离与验证性信息加工的负相关关系会得到显著增强, 而在高解释水平(高期许性-低可行性特征)条件下, 时间距离与验证性信息加工的负相关关系会得到显著降低。     

Effects of shifts in the rate of repetitive stimulation on sustained attention

The effects of shifts in the rate of presentation of repetitive neutral events (background event rate) were studied in a visual vigilance task. Four groups of subjects experienced either a high (21 events/min) or a low (6 events/min) event rate for 20 min and then experienced either the same or the alternate event rate for an additional 40 min. The temporal occurrence of critical target signals was identical for all groups, irrespective of event rate. The density of critical signals was 12 signals/20 min. By the end of the session, shifts in event rate were associated with changes in performance which resembled contrast effects found in other experimental situations in which shift paradigms were used. Relative to constant event rate control conditions, a shift from a low to a high event rate depressed the probability of signal detections, while a shift in the opposite direction enhanced the probability of signal detections.     

The force/force-variability relationship under controlled temporal conditions

Previously, an inverted U relationship between force and force variability was demonstrated in both static and dynamic responses. Recent research suggests that the inverted U function may be due to a lack of control of the temporal aspects of the response. To investigate this hypothesis, we examined the relationship between force and force variability in rapid movements under controlled temporal conditions. Subjects (N = 4) made rapid reversal responses with a horizontal lever (using elbow flexion and extension) such that the time to reversal (160 ms) and the distance to reversal (45 degrees ) were held constant in each of six load conditions (either 0,.260,.780, 1.040, or 1.560 kg added to the lever). When time to reversal and time to peak acceleration were held constant, a curvilinear relationship between force and force variability resulted, suggesting that the inverted U function is related to control of the temporal aspects of the response.

概率贴现和时间贴现在人脑中的分离

本研究运用ERP技术来检验概率贴现和时间贴现是否反映了相同的神经机制过程。在本研究中,我们在一个刺激中同时操纵概率贴现（风险vs.安全）和时间贴现（1个月后vs.今天）水平。通过对两个过程上的ERN以及全时间段的ERP分析来确定它们是否反映了相同的认知过程。结果发现,这两者在ERN上存在差异,同时这两个效应在ERP的时程和出现的电极点上都存在差异。这些差异表明这两者可能包含着不同的神经机制过程。
