Why There Cannot be Any Such Thing as “Time Travel”

Extending work of Wittgenstein, Lakoff and Johnson I suggest that it is the (spatial) metaphors we rely on in order to conceptualise time that provide an illusory space for time‐travel‐talk. For example, in the “Moving Time” spatialisation of time, “objects” move past the agent from the future to the past. The objects all move in the same direction – this is mapped to time always moving in the same direction. But then it is easy to imagine suspending this rule, and asking why the objects should not start moving in the opposite direction. This is one way of generating the idea of time‐travel “back” into the past. Time‐travel‐talk essentially involves the unaware projection of fragments of our time‐talk – taken from powerful conceptual metaphors – onto the nature of reality itself. Understanding this dissolves away the charm and attractions of such talk.     

How the physicality of space affects how we think about time

Time is an abstract concept that may be better understood when mapped onto space. For English speakers, typically a timeline is used that runs horizontally from left (past) to right (future) (Boroditsky, Fuhrman, & McCormick, 2011) and can be separated into regions, past and future. However, it is unclear from prior research how these regions along the timeline are differentiated. In addition, although for English speakers time is typically thought of in terms of a left–right axis, gestures and metaphors that conceptualize the past as behind and the future as ahead are prevalent, implicating the use of a front–back axis. In three experiments, participants made temporal judgments of pictures while holding their hands in various positions around their bodies, to assess whether the body or hands or both are used as anchors to differentiate regions and whether the front–back axis can be used as a timeline. In Experiment 1 we found independent influences of the body and the hands in anchoring the left–right axis. In Experiment 2 we found support for the use of the front–back axis to map time, with independent influences of the body and the hands in anchoring this axis as well. In Experiment 3 we demonstrated that the timeline must be configured in a way that is consistent with underlying conceptualizations of time, by showing that the above–below axis is not used for English speakers. Together, these results indicate that time is mapped onto space, with this mapping being constrained by underlying conceptualizations of time.     

Psychological distance and emotional experience: what you see is what you get

Recent research suggests that perceiving negative emotion-eliciting scenes approaching intensifies the associated felt emotion, while perceiving emotion-eliciting scenes receding weakens the associated felt emotion (Muhlberger, Neumann, Wieser, & Pauli, 2008). In the present studies, we sought to extend these findings by examining the effects of imagining rather than perceiving such changes to negative emotion-eliciting scenes. Across three studies, we found that negative scenes generally elicited less negative responses and lower levels of arousal when imagined moving away from participants and shrinking, and more negative responses and higher levels of arousal when imagined moving toward participants and growing, as compared to the responses elicited by negative scenes when imagined unchanged. Patterns in responses to neutral scenes undergoing the same imagined transformations were similar on ratings of emotional arousal, but differed on valence-generally eliciting greater positivity when imagined moving toward participants and growing, and less positivity when imagined moving away from participants and shrinking. Moreover, for these effects to emerge, participants reported it necessary to explicitly imagine scenes moving closer or farther. These findings have implications for emotion regulation, and suggest that imagined spatial distance plays a role in mental representations of emotionally salient events.     

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。     

The socio-ecological psychology of residential mobility

From ancient time, Homo sapiens moved around in search of a better life. Although the development of agriculture and industrialization no longer necessitates frequently moving to find new food sources, people today still change their residences for a variety of reasons. This article highlights key findings from residential mobility, focusing on its implications for the self, social relationships, societies, and well-being. Generally, residential mobility shifts individual attention away from collective attributes toward personal attributes. It also changes people's relationship styles and preferences, leading individuals to favor wider social networks, more open communication, low-commitment groups, and egalitarian helpers. In addition, it increases tolerance for norm violations and moral deviations. Lastly, residential mobility can explain some cross-national and within-nation variations. This article reviews recent psychological research on residential mobility and then discusses limitations, paradoxical findings, and future directions.     

Response Style: A Basis for Rorschach Construct Validity

The Rorschach test situation was defined as an ambiguous power relationship in which the S could respond either by moving away from (Recognition), moving toward (Reaction) or moving against (Proaction) the E. Construct validity was approached by predicting both to a trait (trait validity) and to a different theoretical system (nomological validity). To evaluate trait validity it was predicted that yielders would have more Reactive responses than non-yielders and that non-yielders would have more Proactive responses than yielders. Nomological validity was investigated by predicting into Schachter's (1959) theory of affiliation. First born and only children should produce more Reactive scores than late born children and late born children should produce more Proactive responses than first and only children. The prediction that the non-yielders would produce more Proactive scores than yielders was not sustained. However, the hypotheses about yielding and Reaction, first and only children and Reaction, and late children and Proaction were sustained.     

Karma or Immortality: Can Religion Influence Space‐Time Mappings?

People implicitly associate the “past” and “future” with “front” and “back” in their minds according to their cultural attitudes toward time. As the temporal focus hypothesis (TFH) proposes, future‐oriented people tend to think about time according to the future‐in‐front mapping, whereas past‐oriented people tend to think about time according to the past‐in‐front mapping (de la Fuente, Santiago, Román, Dumitrache, & Casasanto, 2014). Whereas previous studies have demonstrated that culture exerts an important influence on people's implicit spatializations of time, we focus specifically on religion, a prominent layer of culture, as potential additional influence on space‐time mappings. In Experiment 1 and 2, we observed a difference between the two religious groups, with Buddhists being more past‐focused and more frequently conceptualizing the past as ahead of them and the future as behind them, and Taoists more future‐focused and exhibiting the opposite space‐time mapping. In Experiment 3, we administered a religion prime, in which Buddhists were randomly assigned to visualize the picture of the Buddhas of the Past (Buddha Dipamkara) or the Future (Buddha Maitreya). Results showed that the pictorial icon of Dipamkara increased participants' tendency to conceptualize the past as in front of them. In contrast, the pictorial icon of Maitreya caused a dramatic increase in the rate of future‐in‐front responses. In Experiment 4, the causal effect of religion on implicit space‐time mappings was replicated in atheists. Taken together, these findings provide converging evidence for the hypothesized causal role of religion for temporal focus in determining space‐time mappings.     

Perceptual learning can reverse subliminal priming effects

Masked primes presented prior to a target can result in inverse priming (i.e., benefits on trials in which the prime and the target are mapped onto opposite responses). In five experiments, time-of-task effects on subliminal priming of motor responses were investigated. First, we replicated Klapp and Hinkley's (2002) finding that the priming effect is initially straight (i.e., it benefits congruent trials, in which the prime and targets are mapped onto the same response) or absent, and only later reverses (i.e., faster responses in incongruent than in congruent trials). We show that the presentation of the mask plays a crucial role in this reversal and that the reversal occurs later if the mask pattern is very complex. We suggest that perceptual learning improves the recognition of task-relevant features. Once recognized, these features can trigger the preparation of the alternative response and/or inhibit the prime-activated response. These findings support an active role of the mask in priming.     

Nonattentional effects of nonpredictive central cues

Recent evidence suggests that nonpredictive gaze, hand, arrow, and peripheral cues elicit shifts of reflexive attention. In the present article, we address whether these cues also influence the decision criterion in a go/no-go task. Nonpredictive central gaze and hand cues pointed toward or away from the location of an imminent target. Responses to the targets were faster, and false alarm errors were more frequent, when cues pointed toward the target than when they were directed away from it. Although a similar pattern was observed with nonpredictive arrow cues, it was not seen with nonpredictive peripheral cues. These results suggest that nonpredictive central cues not only affect attention, but also bias decision processes.     

Gaining and losing social support: Momentum in decision-making groups

This paper addressed the question, is there a momentum effect in decision-making groups? That is, does movement toward a decision alternative encourage further similar movement? In the first two of three experiments, the movement of group members toward or away from a subject's preference was manipulated while holding constant the content of group discussion. The only significant effect of such shifts in position was an antimomentum effect; e.g., subjects were less likely to move toward an alternative which had gained a supporter than if no such shift in position had occurred. These experiments also demonstrated that the inverse relationship between overall level of support and likelihood of changing one's position (the “strength-in-numbers” effect) was not solely attributable to larger factions' ability to generate more arguments than smaller factions. In a final experiment, subjects were given an opportunity to defend their preference; under these conditions, the loss of a supporter might result in momentum-producing attributions (e.g., my arguments are unconvincing). However, these experimental conditions did not produce a momentum effect. Analyses of the content of subjects' speech paralleled the data on opinion change in these and previous studies—subjects were much more sensitive to current levels of support than to changes in the level of support. The antimomentum effect observed in Experiment 2 was attributed to a sensitivity to both one's current and past levels of support in the group.     

Irrelevant response effects improve serial learning in serial reaction time tasks

Tones were introduced into a serial reaction time (SRT) task to serve as redundant response effects. Experiment 1 showed that the tones improved serial learning with a 10-element stimulus sequence, but only if the tone effects were mapped onto the responses contingently. Experiment 2 demonstrated that switching to noncontingent response-effect mapping increased SRT only when participants had previously adapted to contingent response-effect mapping. In Experiment 3, the beneficial influence of contingent tone effects on serial learning occurred only when there was sufficient time between the response effects and the next imperative stimuli. The results are discussed in terms of the ideomotor principle. It is claimed that an internal representation of the to-be-produced tone effects develops and gains control over the execution of the response sequence.     

Affective states leak into movement execution: Automatic avoidance of threatening stimuli in fear of spider is visible in reach trajectories

Approach-like actions are initiated faster with stimuli of positive valence. Conversely, avoidance-like actions are initiated faster with threatening stimuli of negative valence. We went beyond reaction time measures and investigated whether threatening stimuli also affect the way in which an action is carried out. Participants moved their hand either away from the picture of a spider (avoidance) or they moved their hand toward the picture of a spider (approach). We compared spider-fearful participants to non-anxious participants. When reaching away from the threatening spider picture, spider-fearful participants moved more directly to the target than controls. When reaching toward the threatening spider, spider-fearful participants moved less directly to the target than controls. Some conditions that showed clear differences in movement trajectories between spider-fearful and control participants were devoid of differences in reaction time. The deviation away from threatening stimuli provides evidence for the claim that affective states like fear leak into movement programming and produce deviations away from threatening stimuli in movement execution. Avoidance of threatening stimuli is rapidly integrated into ongoing motor behaviour in order to increase the distance between the participant's body and the threatening stimulus.     

“Mother nature doesn’t have a bullet with your name on it”: Coding with reference to one’s name or object location?

When movements of a joystick toward/away from the self are made in response to positive/negative words, performance is better with the positive-toward/negative-away mapping than with the alternative mapping, consistent with an approach-avoidance motivational account. Markman and Brendl (2005) instructed participants to move a positive or negative word toward or away from their name, located on a bar at the center of a three-dimensional display. The positive-toward/negative-away mapping relative to the name’s location was preferred, which means that relative to the body the preferred mapping reversed to positive-away/negative-toward when the word was in front of the name. This finding was interpreted as demonstrating that “the compatibility effect depends on people’s representation of their selves in space rather than on their physical location” (p. 6). Alternatively, this effect may arise from the bar providing a salient referent object for coding relative location. We report an experiment that replicates these findings but shows similar results when there is no name on the bar and/or no three-dimensional perspective. An account in terms of action effects involving implied movement of the word toward or away from a referent object rather than a representation of self provides the simplest explanation of the compatibility effect.     

Grounding language in action

We report a new phenomenon associated with language comprehension: the action-sentence compatibility effect (ACE). Participants judged whether sentences were sensible by making a response that required moving toward or away from their bodies. When a sentence implied action in one direction (e.g., "Close the drawer" implies action away from the body), the participants had difficulty making a sensibility judgment requiring a response in the opposite direction. The ACE was demonstrated for three sentences types: imperative sentences, sentences describing the transfer of concrete objects, and sentences describing the transfer of abstract entities, such as "Liz told you the story." These dataare inconsistent with theories of language comprehension in which meaning is represented as a set of relations among nodes. Instead, the data support an embodied theory of meaning that relates the meaning of sentences to human action.     

Pathways to intercultural accuracy: Social projection processes and core cultural values

The present research examines intercultural accuracy—people's ability to make accurate judgments about outgroup values—and the role of social projection processes. Across four studies, U.S. and British participants showed low overall levels of intercultural accuracy for Chinese students’ individualistic and collectivistic values. In line with recent changes toward individualism in China, we observed different levels of intercultural accuracy, hinging on whether the criterion values of Chinese were assessed before (2001) or after (2015) this shift. Important for the study of social projection, we observed that U.S./British participants projected their values onto the outgroup. Social projection tendency (measured in Study 2 and manipulated in Study 3) was associated with greater intercultural accuracy. The relationship between projection and accuracy also depended on the shifts in individualistic values of Chinese. Important for the study of intergroup relations, accuracy was positively associated with interest in future relationships with the Chinese.     

Relative contributions of face and body configurations: Perceiving emotional state and motion intention

This study addressed the relative reliance on face and body configurations for different types of emotion-related judgements: emotional state and motion intention. Participants viewed images of people with either emotionally congruent (both angry or fearful) or incongruent (angry/fearful; fearful/angry) faces and bodies. Congruent conditions provided baseline responses. Incongruent conditions revealed relative reliance on face and body information for different judgements. Body configurations influenced motion-intention judgements more than facial configurations: incongruent pairs with angry bodies were more frequently perceived as moving forward than those with fearful bodies; pairs with fearful bodies were more frequently perceived as moving away. In contrast, faces influenced emotional-state judgements more, but bodies moderated ratings of face emotion. Thus, both face and body configurations influence emotion perception, but the type of evaluation required influences their relative contributions. These findings highlight the importance of considering both the face and body as important sources of emotion information.

三维虚拟空间中转头选中远离和靠近运动目标的操作特性差异

通过转头选中运动目标是虚拟现实(VR)中的常见操作,然而运动目标包含远离和靠近运动,确定两类操作的时间特性差异对设计高效的用户接口有重要的意义。本研究选取17名被试在VR中通过转头将球体光标快速准确地放入水平运动的球体目标内,并改变初始距离、目标容差和目标速度。总时间结果显示,远离运动的操作难度更大,初始距离和目标容差对远离和靠近运动的影响相似,目标速度对两类运动的影响相反。进一步将光标的移动过程划分为加速、减速和调整阶段,结果发现,远离运动的加速和减速时间大于靠近运动,但是两类运动的调整时间接近,并且只有目标容差对两类运动的影响一致。最后构建了总时间与三因素的函数模型,成功解释了两类运动的操作时间特性。本研究证明了远离与靠近运动具有不同的操作时间特性,为两类运动的独立交互设计提供了重要参考。     

Newborns' preference for goal-directed actions

The central role of sensory-motor representations in cognitive functions is almost universally accepted. However, determining the link between motor execution and its sensory counterpart and when, during ontogenesis, this link originates are still under investigation. The aim of the present study is to investigate whether at birth this link is already present and 2-day-old newborns are able to discriminate between visual cues indicating goal-directed or non-goal-directed actions. Here, with a preferential looking technique, a hand grasping a ball was the observed movement and we orthogonally manipulated the three factors necessary to successfully reach the goal: (a) presence of the ball, (b) direction of the arm movement, and (c) hand shaping. Results indicated that newborns orient more frequently and look longer at a hand shape for whole hand prehension but only when the movement is directed away from the body and toward the external world. In addition, newborns prefer the away from the body movement only when the object is present. We argue that newborns prefer a movement directed toward the external world only when it may develop into a purposeful movement because of the presence of the to-be-grasped object. Overall, our results support the existence of primitive sensory-motor associations since the first days after birth.
