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.     

Using virtual environments to assess visual perception judgements in patients with Parkinson’s disease

Visual perception is an exceedingly critical concern in the daily lives of older people, particularly for determining traffic behaviors. In this study, two simulation experiments were conducted to determine the difference in visual perception judgement ability between healthy older individuals and patients with Parkinson’s disease (PD) in simulated environments. The first experiment conducted in this study manipulated the sizes of different depth cues, reference objects, and vehicle size, and also requested participants to determine the distances between objects in different images to determine differences in depth perception between different groups. The second experiment simulates the participant in predicting the time to reach the front target in the driving state. In the experiment, different distances and different speeds are used to understand whether the participants of different groups will have differences in the time prediction. The results of the first experiment demonstrated that patients with PD exhibited significant depth perception degeneration in judging object distances. The second experiment revealed that when vehicles were traveling at high speeds, participants considerably underestimated vehicle speed. The results of this study demonstrate that patients with PD experience a degree of degeneration in terms of depth perception and perception of dynamic distance prediction. This result can assist patients with PD in understanding their visual perception degeneration and improving traffic awareness.

The mental representation of integers: an abstract-to-concrete shift in the understanding of mathematical concepts

Mathematics has a level of structure that transcends untutored intuition. What is the cognitive representation of abstract mathematical concepts that makes them meaningful? We consider this question in the context of the integers, which extend the natural numbers with zero and negative numbers. Participants made greater and lesser judgments of pairs of integers. Experiment 1 demonstrated an inverse distance effect: When comparing numbers across the zero boundary, people are faster when the numbers are near together (e.g., −1 vs. 2) than when they are far apart (e.g., −1 vs. 7). This result conflicts with a straightforward symbolic or analog magnitude representation of integers. We therefore propose an analog-x hypothesis: Mastering a new symbol system restructures the existing magnitude representation to encode its unique properties. We instantiate analog-x in a reflection model: The mental negative number line is a reflection of the positive number line. Experiment 2 replicated the inverse distance effect and corroborated the model. Experiment 3 confirmed a developmental prediction: Children, who have yet to restructure their magnitude representation to include negative magnitudes, use rules to compare negative numbers. Taken together, the experiments suggest an abstract-to-concrete shift: Symbolic manipulation can transform an existing magnitude representation so that it incorporates additional perceptual-motor structure, in this case symmetry about a boundary. We conclude with a second symbolic-magnitude model that instantiates analog-x using a feature-based representation, and that begins to explain the restructuring process.     

The effect of construal level on predictions of task duration

Construal level theory (Trope & Liberman, 2010) contends that distance to events leads to higher level processing. In a series of studies, we examined the role of construal level in prediction of the time needed to perform a task. Estimates increased when the tasks were distant rather than close in time (Study 1), were hypothetical rather than real (Study 2), and when participants were primed to adopt an abstract rather than a concrete mindset (Study 3). As a possible explanation, it is suggested that time units are perceived as smaller as people move up in abstraction, so that more time units are needed to cover the same amount of work. In line with this, we found that people who were primed to adopt a higher level processing mode visualized an hour as shorter than those in a lower level mode, as indicated by their distance marks on a time-line (Study 4). Finally, the contraction of time units was shown to mediate the relationship between temporal distance and task duration estimates (Study 5).     

Psychological distance to reward: Effects of S+ duration and the delay reduction it signals

A concurrent-chains procedure was used to examine choice between segmented (two-component chained schedules) and unsegmented schedules (simple schedules) in terminal links with equal inter-reinforcement intervals. Previous studies using this kind of experimental procedure showed preference for unsegmented schedules for both pigeons and humans. In this study, two changes in the experimental procedure were made relative to the usual experimental procedure reported in the literature. The first was that in the segmented schedule the second terminal-link stimulus appeared close to reinforcement presentation and the second was that the change in stimulus was brief, allowing the first stimulus to reappear and to be contiguous with reinforcement. With these changes, preference occurred for the segmented schedule. This result is consistent with principles of conditioned reinforcement, including delay-reduction theory.     

Familiarity with and social distance from people with mental illness: Testing the mediating effects of prejudiced attitudes

The purpose of this study was to examine prejudiced attitudes as a factor associated with social distance from people with mental illness. A total of 289 university students from Greece completed written measures assessing social distance from, prejudiced attitudes about, and familiarity with mental illness. A structural equation model with manifest variables was tested. Participants who reported to be more familiar with mental illness held stronger social care and weaker prejudiced beliefs, and consequently expressed a less strong desire for social distance. Implications of the results and suggestions for future research are outlined. Copyright © 2011 John Wiley & Sons, Ltd.     

Secondary Transfer Effect of Intergroup Contact: The Role of Intergroup Attitudes,Intergroup Anxiety and Perspective Taking

We conducted a field study to investigate the secondary transfer effect of intergroup contact, consisting in the generalisation of the positive effects of intergroup contact to outgroups uninvolved in the contact situation. Italian secondary school students (N = 175) filled out a questionnaire; the effects of prior contact were statistically controlled. Results showed that contact with immigrants improved attitudes toward them. In turn, these attitudes generalised to attitudes toward two dissimilar outgroups not directly involved in contact: disabled and homosexuals. Notably, we found evidence for a secondary transfer effect of intergroup anxiety and perspective taking, which generalised from immigrants to the disabled and homosexuals. Evidence was found for the mediating role of intergroup attitudes, intergroup anxiety and perspective taking. The theoretical and practical implications of findings are discussed.

Charity Begins at Home: Cultural Differences in Social Discounting and Generosity

People often consider how their actions influence others when making decisions. However, we are not equally generous to everyone alike. Our willingness to share resources declines as a function of social distance between the decision maker and the recipient. This function is likely to be influenced by culture, but research on behavioral decision making is still lacking empirical evidence. In Western societies, individuals generally perceive themselves as autonomous and independent from others, whereas the distinction between self and close others is less sharply defined by Eastern individuals where relationships and group membership are more centralized. Therefore, the social discount function should reflect this difference in the distinction of self and others by a reduced decline in generosity over close social distances. A social decision‐making task was adapted to the intercultural context, and data were collected in Germany and China. For seven different social distances, we estimated how much money German and Chinese subjects were willing to forego to give a certain reward to another person. A hyperbolic model was fitted to the data. We found that other‐regarding generosity declines as a function of social distance independent of cultural identity. However, German subjects showed a marked drop in generosity across close social distances, which was significantly less pronounced in Chinese participants. Copyright © 2013 John Wiley & Sons, Ltd.
