Linguistic asymmetry,egocentric anchoring,and sensory modality as factors for the observed association between time and space perception

Temporal and spatial representations have been consistently shown to be inextricably intertwined. However, the exact nature of time–space mapping remains unknown. On the one hand, the conceptual metaphor theory postulates unilateral, asymmetric mapping of time onto space, that is, time is perceived in spatial terms but the perception of space is relatively independent of time. On the other hand, a theory of magnitude assumes bilateral and symmetric interactions between temporal and spatial perceptions. In the present paper, we argue that the concepts of linguistic asymmetry, egocentric anchoring, and sensory modality provide potential explanations for why evidences favoring both asymmetry and symmetry have been obtained. We first examine the asymmetry model and suggest that language plays a critical role in it. Next, we discuss the symmetry model in relation to egocentric anchoring and sensory modality. We conclude that since these three factors may jointly account for some conflicting past results regarding the strength and directionality of time–space mapping, they should be taken into serious consideration in future test designs.     

Use of the anchoring and adjustment heuristic by children

Two studies are discussed in which children's use of the anchoring and adjustment heuristic was considered. Study one is a modification of the classic multiplication task devised by Kahneman and Tversky (1974). Results indicate that children in grades 4, 6, 8 and adults are affected by the order of numbers provided in an addition task. In addition, younger children display the tendency to over adjust, yielding higher estimates. In the second study, third and fifth grade participants and adults were provided anchors and estimated the number of jellybeans in a glass container. A main effect for condition is indicated, with lower anchors leading to lower estimates. Results of both studies are consistent with the an anchoring and adjustment explanation.

视觉观点采择中自我中心性偏差的抑制和归因之争

自我中心性偏差是社交失败的重要原因,但其产生机制还存在争议。以往研究存在抑制性选择模型与流利性错误归因两种理论观点:前者认为对自身观点的抑制失败会导致自我中心性偏差;后者则认为错误地选择自身更为流畅的信息会导致自我中心性偏差。为整合上述争论,提出抑制-归因协同作用模型,认为抑制和归因两种加工或可共同导致自我中心性偏差。未来研究应借助精巧的研究范式和特殊被试群体,进一步验证该模型。     

Putting adjustment back in the anchoring and adjustment heuristic: differential processing of self-generated and experimenter-provided anchors

People's estimates of uncertain quantities are commonly influenced by irrelevant values. These anchoring effects were originally explained as insufficient adjustment away from an initial anchor value. The existing literature provides little support for the postulated process of adjustment, however, and a consensus that none takes place seems to be emerging. We argue that this conclusion is premature, and we present evidence that insufficient adjustment produces anchoring effects when the anchors are self-generated. In Study 1, participants' verbal reports made reference to adjustment only from self-generated anchors. In Studies 2 and 3, participants induced to accept values by nodding their heads gave answers that were closer to an anchor (i.e., they adjusted less) than participants induced to deny values by shaking their heads—again, only when the anchor was self-generated. These results suggest it is time to reintroduce anchoring and adjustment as an explanation for some judgments under uncertainty.     

Effects of anchoring and adjustment in the evaluation of product pricing

Anchoring and adjustment comprise a heuristic that creates expectations. Two types of anchors were applied on participants' evaluation of products: the price reference of the product (maximum, minimum, or no price reference) and the context in which the products were evaluated (the prestige of the shopping center). Results showed that both factors anchored evaluations of products' value. Context effects were explained by the different expectations of visitors in prestigious (looking for quality) and less prestigious (seeking a bargain) centers.     

Fostering team creativity: Perspective taking as key to unlocking diversity's potential

Despite the clear importance of team creativity for organizations, the conditions that foster it are not very well understood. Even though diversity, especially diversity of perspectives and knowledge, is frequently argued to stimulate higher creativity in teams, empirical findings on this relationship remain inconsistent. We have developed a theoretical model in which the effect of a team's diversity on its creativity is moderated by the degree to which team members engage in perspective taking. We propose that perspective taking helps realize the creative benefits of diversity of perspectives by fostering information elaboration. Results of a laboratory experiment support the hypothesized interaction between diversity and perspective taking on team creativity. Diverse teams performed more creatively than homogeneous teams when they engaged in perspective taking, but not when they were not instructed to take their team members' perspectives. Team information elaboration was found to mediate this moderated effect and was associated with a stronger indirect effect than mere information sharing or task conflict. Our results point to perspective taking as an important mechanism to unlock diversity's potential for team creativity. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Perspective taking promotes action understanding and learning

People often learn actions by watching others. The authors propose and test the hypothesis that perspective taking promotes encoding a hierarchical representation of an actor's goals and subgoals-a key process for observational learning. Observers segmented videos of an object assembly task into coarse and fine action units. They described what happened in each unit from either the actor's, their own, or another observer's perspective and later performed the assembly task themselves. Participants who described the task from the actor's perspective encoded actions more hierarchically during observation and learned the task better.     

Perspective taking, pictures, and the blind

Congenitally blind, late blind, and blindfolded sighted controls attempted a Piagetian perspective-taking (three-mountain) task. Piaget used the term perspective to mean point of view (Piaget & Inhelder, 1967, p. 210), and the present usage does not imply linear perspective. Subjects used raised-line drawings to depict alternative points of view of an array of three geometric solid forms (cube, cone, and ball). They then identified the point of view of raised-line drawings. The effect of visual status on accuracy was nonsignificant for both response measures. Using alternating vision of the array and drawings, sighted subjects in a control condition performed like the congenitally blind. However, congenitally blind individuals did require more time than the other subjects for the perspective-taking task. In an additional experiment, no difference was found between the three groups in the accuracy or speed of tactile shape matching. The results suggest that visual imagery and visual experience are not necessary for tactile perspective taking.     

Intensity and reverberation as factors in the auditory perception of egocentric distance

Both auditory intensity and reverberation have previously been shown to be sufficient to produce systematically varying judgments of perceived distance when several values of the variable are presented repeatedly to the same observer. Such studies do not, however, indicate clearly whether these cues are functioning in an absolute or in a relative manner. An absolute cue to auditory distance would require that two groups presented with different values of the variable in question should report different values of perceived distance. Two experiments are reported in which intensity variation and reverberation are examined. The results showed that auditory intensity differences over a range of 20 dB did not serve as an absolute cue to auditory distance, but could serve as a strong cue to changes in such distance. A comparison of data obtained in a normally reverberatory setting (Experiment 1) and an anechoic chamber (Experiment 2) indicated that the state of reverberation could serve as an absolute cue, with greater reverberation being associated with greater perceived distances. Some of the results were discussed in terms of the possibility that the specific distance tendency (a concept developed to handle some phenomena in visual space perception) might have applicability to the study of auditory perceived distance as well.

     

Perspective taking in children's narratives about jealousy

This study explored relationships between perspective‐taking, emotion understanding, and children's narrative abilities. Younger (23 5‐/6‐year‐olds) and older (24 7‐/8‐year‐olds) children generated fictional narratives, using a wordless picture book, about a frog experiencing jealousy. Children's emotion understanding was assessed through a standardized test of emotion comprehension and their ability to convey the jealousy theme of the story. Perspective‐taking ability was assessed with respect to children's use of narrative evaluation (i.e., narrative coherence, mental state language, supplementary evaluative speech, use of subjective language, and placement of emotion expression). Older children scored higher than younger children on emotion comprehension and on understanding the story's complex emotional theme, including the ability to identify a rival. They were more advanced in perspective‐taking abilities, and selectively used emotion expressions to highlight story episodes. Subjective perspective taking and narrative coherence were predictive of children's elaboration of the jealousy theme. Use of supplementary evaluative speech, in turn, was predictive of both subjective perspective taking and narrative coherence.

Perspective taking and theory of mind in hide and seek

Does theory of mind play a significant role in where people choose to hide an item or where they search for an item that has been hidden? Adapting Anderson’s "Hide-Find Paradigm" Anderson et al. (Action, Perception and Performance, 76, 907–913, 2014) participants viewed homogenous or popout visual arrays on a touchscreen table. Their task was to indicate where in the array they would hide an item, or to search for an item that had been hidden, by either a friend or a foe. Critically, participants believed that their sitting location at the touchtable was the same as—or opposite to—their partner's location. Replicating Anderson et al., participants tended to (1) select items nearer to themselves on homogenous displays, and this bias was stronger for a friend than foe; and (2) select popout items, and again, more for a friend than foe. These biases were observed only when participants believed that they shared the same physical perspective as their partner. Collectively, the data indicate that theory of mind plays a significant role in hiding and finding, and demonstrate that the hide-find paradigm is a powerful tool for investigating theory of mind in adults.     

The egocentric bias: Seeing oneself as cause and target of others' behavior

The egocentric bias—the tendency to see oneself as both cause and target of another person's behavior—was examined in the context of a small group interaction. Pairs of subjects plus a confederate conducted a short discussion, their goal being to achieve consensus on a specific topic. The discussion was interrupted by the experimenter when the confederate summarized his/her opinion. It was found that subjects were more likely to see themselves as a cause as well as a target of the confederate's last statement compared to the way they were seen by other group members. Subjects were also more likely to exaggerate the amount of attention they received from the confederate. The overall egocentric bias scores were correlated with subjects' level of self-esteem. Cognitive and motivational processes that may account for this bias were discussed.     

Perspective taking combats automatic expressions of racial bias

Five experiments investigated the hypothesis that perspective taking--actively contemplating others' psychological experiences--attenuates automatic expressions of racial bias. Across the first 3 experiments, participants who adopted the perspective of a Black target in an initial context subsequently exhibited more positive automatic interracial evaluations, with changes in automatic evaluations mediating the effect of perspective taking on more deliberate interracial evaluations. Furthermore, unlike other bias-reduction strategies, the interracial positivity resulting from perspective taking was accompanied by increased salience of racial inequalities (Experiment 3). Perspective taking also produced stronger approach-oriented action tendencies toward Blacks (but not Whites; Experiment 4). A final experiment revealed that face-to-face interactions with perspective takers were rated more positively by Black interaction partners than were interactions with nonperspective takers--a relationship that was mediated by perspective takers' increased approach-oriented nonverbal behaviors (as rated by objective, third-party observers). These findings indicate that perspective taking can combat automatic expressions of racial biases without simultaneously decreasing sensitivity to ongoing racial disparities.     

Perspective taking combats the denial of intergroup discrimination

Despite the continuing, adverse impact of discrimination on the lives of racial and ethnic minorities, the denial of discrimination is commonplace. Four experiments investigated the efficacy of perspective taking as a strategy for combating discrimination denial. Participants who adopted a Black or Latino target's perspective in an initial context were subsequently more likely to explicitly acknowledge the persistence of intergroup discrimination than were non-perspective takers (Experiments 1–3) or participants who adopted a White target's perspective (Experiment 1). Perspective taking also engendered more positive attitudes toward a social policy designed to redress intergroup inequalities (i.e., affirmative action), and this relationship was mediated by increased recognition of discrimination (Experiments 2a and 2b). Increased identification with the targeted outgroup, as reflected in automatic associations between the self and African Americans, was found to underlie the effect of perspective taking on sensitivity to discrimination (Experiment 3). The collective findings indicate that perspective taking can effectively combat discrimination denial.     

Perspective taking and emotion: The case of disgust and sadness

In a recent study (Gilead et al., 2016), perspective taking (PT) was found to have a significant effect on affect ratings of negative pictures compared to neutrals. The current study explores the question whether PT would be affected equally by distinct negative emotions. We used neutral pictures and pictures classified as provoking sadness or disgust, matched for their intensity and arousal. Participants were asked to rate the pictures (on a scale from 1—no emotional reaction, to 5—very strong reaction) from 3 different perspectives - tough, sensitive, or their own – “me”. In Experiment 1, all pictures were mixed in the same blocks. In Experiment 2, the sad and disgust pictures were separated into two different blocks (each including neutrals). Both experiments showed significant interaction between PT and emotion. PT was found to be influenced by valence; however, distinct negative emotions were found to affect PT similarly.     

Perspective taking instructions and self-other overlap: Different motives for helping

In two studies (N’s = 57 and 115), we demonstrate that type of perspective-taking instruction (“imagine self” vs. “imagine other”) differentially affects two motives for helping: self-other overlap and empathic concern. Imagine-self instructions produce greater self-other overlap than imagine-target and objective instructions, while both types of perspective-taking instruction promote empathic concern relative to an objective condition. In Study 2, imagine-self instructions indirectly increased the likelihood of helping via empathic concern and self-other overlap, while imagine-target instructions led indirectly to greater helping only through empathic concern. We discuss how different perspective-taking instructions may implicate different emotional and motivational paths to increasing helping.     

Mental rotation with egocentric and object-based transformations

Two experiments were conducted to address methodological issues with past studies investigating the influence of egocentric and object-based transformations on performance and sex differences in mental rotation. In previous work, the egocentric and object-based mental rotation tasks confounded the stimulus type (embodied vs. non-embodied) and transformation task (egocentric vs. object-based). In both experiments presented here, the same stimuli were used regardless of the type of transformation but task instructions were modified to induce either egocentric (left–right judgment) or object-based (same–different judgment) processing. Experiment 1 used pairs of letters whereas Experiment 2 presented pairs of line-drawings of human hands. For both experiments, it was hypothesized that the mental rotation slope for response time would be steeper for object-based than for egocentric transformations. This hypothesis was verified in both experiments. Furthermore, Experiment 2 showed a reduced male advantage for egocentric compared to object-based rotations, whereas this pattern was reversed for Experiment 1. In conclusion, the present study showed that the influence of the type of transformation involved in mental rotation can be examined with the same set of stimuli simply by modifying task instructions.
