时间词呈现形式对空间-时间相容性效应的影响

采用时间区分任务探讨不同刺激形式对于空间-时间相容性效应 (space–time compatibility effect,简称STC效应)的影响。实验一采用倒置时间词作为刺激,发现标准的STC效应,即对过去词,“左”反应更快;对将来词,“右”反应更快。实验二采用镜像反转时间词作为刺激,发现反转的STC效应,即对过去词,“右”反应更快;对将来词,“左”反应更快。这些结果表明刺激呈现形式可以影响STC效应,并进一步支持了书写习惯是这种效应的起源。     

时序表征的空间特性

时间是个高度抽象的概念,必须依靠具体的、易感知的事物进行表征。时间表征本质上是隐喻性的,而时间的空间隐喻是时间隐喻表征的原型。受到数字空间表征研究的启示,发现时序表征同样具有空间特性。时序表征具有空间特性具有一定的普遍性,但是在具体的水平或垂直空间维度、“左-右”或“右-左”空间方向上存在一定的灵活性;此外时序能够导致空间注意的转移。     

空间-时间联合编码效应：来自手动和眼动证据

本研究探讨汉语背景下不同反应方式（手动,眼动）、不同方位（水平,垂直）上空间-时间联合编码效应（STEARC效应）存在的可能性。四个实验均采用两类时间词语诱发被试的时间表征,采用2（时间：过去、将来）×2（反应手/眼跳方向：左、右/上、下）的被试内设计。结果表明汉语背景下的人们将过去和身体左边（上）联系在一起,把将来和右边（下）联系在一起,人们存在自左向右和自上而下的STEARC效应,这种效应不存在手动和眼动的分离,人们对时间的表征不仅是一条时间线,更是一个心理时间地图。     

Space-time compatibility effects in the auditory modality

Previous research suggests that past and future temporal concepts are spatially represented from left to right along a mental line. And these concepts can both prime motor responses to left or right space and direct visual spatial attention. The present study aimed at investigating the nature of this space-time conceptual metaphor in different auditory tasks. In the first experiment, subjects categorized time-related words (past or future) that were presented binaurally. In the second experiment, subjects detected left-ear or right-ear targets following time-related words. The similar space-time compatibility effects were found in these two experiments. Our results demonstrate that the activation of temporal concepts can both prime motor responses to left or right space and influence the orientation of auditory spatial attention, suggesting that the modality of the stimulus input is unimportant for the left-right mapping of time. These results are explained by the "intermediate coding" account.     

Time (also) flies from left to right

Everyday linguistic expressions in many languages suggest that back and front space is projected onto temporal concepts of past and future (as in the sentencewe are years ahead of them). The present experiment tested the psychological reality of a different space-time conceptual metaphor—projecting the past to left space and the future to right space—for which there are no linguistic traces in any language. Participants categorized words as referring to the past or to the future. Irrelevant to this task, words appeared either to the left or right of the screen, and responses were given by keypresses of the left or right hand. Judgments were facilitated when word position and response mapping were congruent with the left-past right-future conceptual metaphor. These results are discussed in the context of current claims about the embodiment of meaning and the possible mechanisms by which conceptual metaphors can be acquired.     

Priming the mental time-line: effects of modality and processing mode

The notion of a mental time-line (i.e., past corresponds to left and future corresponds to right) supports the conceptual metaphor view assuming that abstract concepts like “time” are grounded in cognitively more accessible concepts like “space.” In five experiments, we further investigated the relationship between temporal and spatial representations and examined whether or not the spatial correspondents of time are unintentionally activated. We employed a priming paradigm, in which visual or auditory prime words (i.e., temporal adverbs such as yesterday, tomorrow) preceded a colored square. In all experiments, participants discriminated the color of this square by responding with the left or the right hand. Although the temporal reference of the priming adverb was task irrelevant in Experiment 1, visually presented primes facilitated responses to the square in correspondence with the direction of the mental time-line. This priming effect was absent in Experiments 2, 3, and 5, in which the primes were presented auditorily and the temporal reference of the words could be ignored. The effect, however, emerged when attention was oriented to the temporal content of the auditory prime words in Experiment 4. The results suggest that task demands differentially modulate the activation of the mental time-line within the visual and auditory modality and support a flexible association between conceptual codes.     

道德概念的隐喻表征——从红白颜色、左右位置和正斜字体的维度

随着具身认知的兴起和发展,道德隐喻的研究焕发新活力。在此背景下,本研究从红白颜色、左右位置和正斜字体三个维度考察道德概念的隐喻表征。实验1的结果显示,红白颜色可能并不与道德概念存在隐喻表征。实验2表明,左右位置与道德概念交互作用显著,左边、右边位置分别与不道德概念、道德概念存在一致的隐喻表征。实验3发现,正斜字体对道德概念的判断具有干扰作用,正体字与道德词汇隐喻表征一致,斜体字与不道德词汇隐喻表征一致。研究表明:左右位置、正斜字体与道德概念存在一定的隐喻联结。     

Left–right coding of past and future in language: The mental timeline during sentence processing

The metaphoric mapping theory suggests that abstract concepts, like time, are represented in terms of concrete dimensions such as space. This theory receives support from several lines of research ranging from psychophysics to linguistics and cultural studies; especially strong support comes from recent response time studies. These studies have reported congruency effects between the dimensions of time and space indicating that time evokes spatial representations that may facilitate or impede responses to words with a temporal connotation. The present paper reports the results of three linguistic experiments that examined this congruency effect when participants processed past- and future-related sentences. Response time was shorter when past-related sentences required a left-hand response and future-related sentences a right-hand response than when this mapping of time onto response hand was reversed (Experiment 1). This result suggests that participants can form time–space associations during the processing of sentences and thus this result is consistent with the view that time is mentally represented from left to right. The activation of these time–space associations, however, appears to be non-automatic as shown by the results of Experiments 2 and 3 when participants were asked to perform a non-temporal meaning discrimination task.     

不同时间关注点下的空间-时间联合编码效应

摘 要 本研究旨在探讨时间关注特征对空间-时间反应编码联合效应的影响。采用时间关注点量表将有效被试分为关注过去组和关注未来组,进行反应区分实验。实验代表过去或未来的时间词作为启动刺激,要求被试判断的目标刺激是随后出现在屏幕左或右侧的圆点。结果发现,关注过去的个体对“左/过去词”的反应更快,关注未来的个体对“右/未来词”反应更快。表明时间关注点影响人们的空间-时间联合编码效应,不同的时间关注点产生人们对于过去和未来时间在注意分配上的差异,从而表现出不同的空间表征方式,在“左-右”水平轴上验证了时间关注点假设。     

Eye movements during mental time travel follow a diagonal line

Recent research showed that past events are associated with the back and left side, whereas future events are associated with the front and right side of space. These spatial–temporal associations have an impact on our sensorimotor system: thinking about one’s past and future leads to subtle body sways in the sagittal dimension of space (Miles, Nind, & Macrae, 2010). In this study we investigated whether mental time travel leads to sensorimotor correlates in the horizontal dimension of space. Participants were asked to mentally displace themselves into the past or future while measuring their spontaneous eye movements on a blank screen. Eye gaze was directed more rightward and upward when thinking about the future than when thinking about the past. Our results provide further insight into the spatial nature of temporal thoughts, and show that not only body, but also eye movements follow a (diagonal) “time line” during mental time travel.     

A multisensory interaction effect in the conceptual realm of time

Recent studies on the conceptualization of abstract concepts suggest that the concept of time is represented along a left-right horizontal axis, such that left-to-right readers represent past on the left and future on the right. Although it has been demonstrated with strong consistency that the localization (left or right) of visual stimuli could modulate temporal judgments, results obtained with auditory stimuli are more puzzling, with both failures and successes at finding the effect in the literature. The present study supports an account based on the relative relevance of visual versus auditory-spatial information in the creation of a frame of reference to map time: The auditory location of words interacted with their temporal meaning only when auditory information was made more relevant than visual spatial information by blindfolding participants.     

盲人的时间水平方向隐喻的通道特异性

通过2个实验, 考察了感觉通道对盲人的时间水平方向隐喻的影响。实验1发现, 盲人只在动作水平上存在同阅读方向一致的时间水平方向隐喻, 对表征过去的词或句子按左键反应和对表征将来的词或句子按右键反应时更快, 表明盲人用于隐喻时间的空间信息是知觉性的。实验2比较了明眼人可视组被试和明眼人遮眼组被试的时间空间隐喻, 发现明眼人可视组被试只在动作水平上存在时间水平方向隐喻, 明眼人遮眼组被试只在刺激在右侧时呈现才出现动作水平的时间水平方向隐喻。综合分析表明, 盲人和明眼人可视组被试的反应更为接近, 表明盲人的时间空间隐喻未受听觉信息的影响。盲人通过运动通道获得的空间认知代偿了视觉通道信息的缺失。     

Free viewing perceptual asymmetries for judgment of brightness and quantity: dependence on stimulus orientation

Previous research has indicated that normals exhibit strong leftward biases during free-viewing perceptual judgments of brightness and quantity. When participants view two symmetrical objects and they are forced to choose which object appears darker or more numerous, participants usually select the stimulus with the relevant feature on the left side. The present study investigated the possibility that these perceptual asymmetries are dependent on scanning a stimulus horizontally across the midline by administering a task with two rectangular reversed stimuli presented either horizontally or vertically. When the stimuli were presented horizontally (crossing the midline), participants exhibited leftward biases, but these biases disappeared when the stimuli were presented vertically. This result supports the position that free-viewing perceptual asymmetries are dependent on scanning the stimuli across the midline.     

空间-时间关联的中介共同表征结构:来自反转STEARC效应的证据

通过3个双任务实验(诱导任务和特征任务)探讨空间-时间联合编码(STEARC)效应的加工机制。实验1采用时间信息作为诱导任务材料,实验2采用空间信息作为诱导任务材料,在特征任务中都发现映射不一致组被试(看到过去/左侧刺激时按右键反应,看到未来/右侧刺激时按左键反应)出现反转STEARC效应,映射一致组被试表现出常规的STEARC效应,表明从时间信息加工到空间反应过程符合中介共同表征结构。实验3分离两种任务的反应方式(手动和眼动),发现不一致映射规则下,被试仍然表现出常规的STEARC效应,表明这种中介共同表征结构存在特定联结效应,即在不同反应器中出现时间和空间相互独立的表征结构。总体而言,研究支持空间-时间关联符合中介共同表征结构,并且这种关联中存在反应器特定联结效应。     

Reduced repetition suppression in the occipital visual cortex during repeated negative Chinese personality‐trait word processing

Reduced neural activation have been consistently observed during repeated items processing, a phenomenon termed repetition suppression. The present study used functional magnetic resonance imaging (fMRI) to investigate whether and how stimuli of emotional valence affects repetition suppression by adopting Chinese personality‐trait words as materials. Seventeen participants were required to read the negative and neutral Chinese personality‐trait words silently. And then they were presented with repeated and novel items during scanning. Results showed significant repetition suppression in the inferior occipital gyrus only for neutral personality‐trait words, whereas similar repetition suppression in the left inferior temporal gyrus and left middle temporal gyrus was revealed for both the word types. These results indicated common and distinct neural substrates during processing Chinese repeated negative and neutral personality‐trait words.     

Moderators of Candidate Name‐Order Effects in Elections: An Experiment

Past studies of elections have shown that candidates whose names were listed at the beginning of a list on a ballot often received more votes by virtue of their position. This article tests speculations about the cognitive mechanisms that might be responsible for producing the effect. In an experiment embedded in a large national Internet survey, participants read about the issue positions of two hypothetical candidates and voted for one of them in a simulated election in which candidate name order was varied. The expected effect of position appeared and was strongest (1) when participants had less information about the candidates on which to base their choices, (2) when participants felt more ambivalent about their choices, (3) among participants with more limited cognitive skills, and (4) among participants who devoted less effort to the candidate evaluation process. The name‐order effect was greater among left‐handed people when the candidate names were arrayed horizontally, but there was no difference between left‐ and right‐handed people when the names were arrayed vertically. These results reinforce some broad theoretical accounts of the cognitive process that yield name‐order effects in elections.     

The sound of time: cross-modal convergence in the spatial structuring of time

In a new integration, we show that the visual-spatial structuring of time converges with auditory-spatial left-right judgments for time-related words. In Experiment 1, participants placed past and future-related words respectively to the left and right of the midpoint on a horizontal line, reproducing earlier findings. In Experiment 2, neutral and time-related words were presented over headphones. Participants were asked to indicate whether words were louder on the left or right channel. On critical experimental trials, words were presented equally loud binaurally. As predicted, participants judged future words to be louder on the right channel more often than past-related words. Furthermore, there was a significant cross-modal overlap between the visual-spatial ordering (Experiment 1) and the auditory judgments (Experiment 2), which were continuously related. These findings provide support for the assumption that space and time have certain invariant properties that share a common structure across modalities.     

Peripheral-foveal scanning and the identification of heteropalindromes in the visual half-fields

The possible identifying properties of the peripheral-field-to-foveal-field (PFTFF) scan, thought to precede the left-to-right reading scan of English alphabetical arrays, were investigated. Heteropalindromes, letter strings that spell one word when read from left to right but another word when read from right to left, were tachistoscopically exposed in the left or right visual fields of 16 male, dextral college students in each of two experiments. The results support Schissler and Baratta's idea that the scan does not appear to yield detailed stimulus information. We suggest that the direction of this scan is well suited to the requirements of encoding horizontally aligned words, given the acuity/information gradient produced when such stimuli are exposed unilaterally. The direction and operation of the scan prior to the left-to-right reading scan are discussed in terms of an earlier account of the encoding of unilaterally exposed, horizontally aligned English words.     

Perceptual and motor congruency effects in time–space association

It is well established that temporal events are represented on a spatially oriented mental time line from left to right. Depending on the task characteristics, the spatial representation of time may be linked to different types of dimensions, including manual response codes and physical space codes. The aim of the present study was to analyze whether manual response and physical space codes are independent of each other or whether they interact when both types of information are involved in the task. The participants performed a temporal estimation task with two lateralized response buttons in four experiments. In the first experiment, the target stimuli were presented on the left side, at the center, or on the right side of the space, whereas the reference stimuli were always presented centrally. The reverse situation was presented in the second experiment. In the third experiment, both stimuli were presented in opposite spatial positions (e.g., left–right), whereas in the last experiment, both stimuli were presented in the same spatial position (e.g., left–left). In all experiments, perceptual and motor congruency effects were found, but no modulation of the congruency effects was found when both the perceptual and motor components were congruent. The results indicated that physical, spatial, and manual response codes are independent from each other for time–space associations, even when both codes are involved in the task. These results are discussed in terms of the “intermediate-coding” account.     

水平空间与情绪效价联结效应的产生机制

采用词汇效价判断任务,考察水平空间与情绪效价联合效应的产生机制。实验1在被试双手正常放置条件下考察了词汇效价与水平空间联结效应的存在;实验2则要求被试双手交叉放置,以考察当反应手和反应键的空间信息冲突时水平空间与情感效价的关联现象;实验3则进一步考排除反应手的参与,以考察口头报告的反应方式是否对两者的联结效应产生影响。结果表明,不同反应方式下均存在空间情感效价的联结,且此联结更多是反应选择极性编码的结果。
