Effects of Perceived Space on Spatial Attention

Abstract—This study demonstrates that a perceptual illusion that alters the perceived length of two lines also affects spatial attention. We used a cuing method that was introduced to study space- versus object-based attention. Two parallel lines of equal length were placed so that the distance between them was equal to the length of the lines. We then added a scene with depth cues to produce a strong illusion that one line was longer than the other. The results showed that spatial attention is distributed in space as it is perceived and altered by perceptual organization. These data have implications for assumptions concerning the spatial medium that guides attention and the role of depth and distance cues in spatial orienting, as well as for understanding attentional systems related to neuropsychological functions that respond to space and objects.     

Contagion and Differentiation in Unethical Behavior: The Effect of One Bad Apple on the Barrel

ABSTRACT— In a world where encounters with dishonesty are frequent, it is important to know if exposure to other people's unethical behavior can increase or decrease an individual's dishonesty. In Experiment 1 , our confederate cheated ostentatiously by finishing a task impossibly quickly and leaving the room with the maximum reward. In line with social-norms theory, participants' level of unethical behavior increased when the confederate was an in-group member, but decreased when the confederate was an out-group member. In Experiment 2 , our confederate instead asked a question about cheating, which merely strengthened the saliency of this possibility. This manipulation decreased the level of unethical behavior among the other group members. These results suggest that individuals' unethicality does not depend on the simple calculations of cost-benefit analysis, but rather depends on the social norms implied by the dishonesty of others and also on the saliency of dishonesty.     

权力感对为自己和为他人消费行为的影响

通过操作消费者的权力感,考察权力感如何影响消费者为自己和为他人消费的行为。实验1采用想象法启动149名被试的权力感,考察不同权力感下,消费者为自己和为他人消费的特点,结果发现,与为他人消费相比,被启动为高权力感的被试为自己花费更多金钱,而启动无权力感的被试为自己花费更少金钱。实验2采用角色扮演法启动对227名被试的权力感,进一步探讨消费者为自己和为他人消费差异的原因,结果发现,低权力者因对他人更依赖而为他人花费更多;而高权力者认为自己更重要,所以为自己花费更多。这些表明,权力感影响消费者为自己和为他人消费的金额。     

Perceptions As Reality: The Influence of Actual and Perceived Demographic Dissimilarity

Two studies were conducted to examine the effects of demographic dissimilarity from others in the workgroup. Results from Study 1 (n = 87 coaches) indicate that actual demographic differences were reliably related to perceptions of such differences. Study 2 investigated the effects of perceived demographic dissimilarity. Data were gathered from an additional 175 coaches. Structural equation modeling indicated that perceived demographic differences were associated with perceived deep-level dissimilarity (i.e., differences in personality, values, and attitudes). In turn, perceived deep-level dissimilarity was negatively related to coworker satisfaction and held a positive association with organizational turnover intentions. Results are discussed in terms of theoretical contributions to the relational demography perspective.     

The Effect of Perceived Advantage and Disadvantage on Performance: The Role of External Efficacy

This experiment examined how perceptions of advantage and disadvantage determine performance in a competitive context. We distinguished between internal and external efficacy, and manipulated external efficacy by inducing perceptions of advantaged or disadvantaged starting positions in a competition, keeping the actual positions equal. The treatment increased the performance of the advantaged party and decreased the performance of the disadvantaged party. In addition, measured external and internal efficacy had qualitatively different effects on performance. The results are explained by the idea that losses loom larger than gains.     

The Effect of Perceived Control on Risk Taking1

The experiment investigates the effect of perceived control on risk taking in a dynamic, everyday task. Using established and validated video simulation techniques, the risk-taking preferences for 96 drivers were measured for a range of driving activities (speed choice, following distance, gap acceptance, and overtaking). The perceived control manipulation was as follows: Half of the participants were told to imagine they were driving the vehicle, and the other half were told to imagine they were passengers. Those who were told to imagine they were driving chose significantly faster speeds than did those who were told to imagine they were passengers. Differences for the other risk-taking measures were not significant. For speed choice, it could be argued that an illusion of control was in operation, such that those who were in control (i.e., drivers) were comfortable with a higher level of risk than those who were not in control (i.e., passengers).     

The Effect of Perceived Locomotor Constraints on Distance Estimation

Two experiments were conducted to examine the ways in which the visual estimation of distance to a target is affected by constraints perceived to be placed on the subsequent locomotion to the target without vision. We hypothesized that an appraisal of impending effort would play a role in ascertaining the distance to be walked. In Experiment 1, the amount of resistance to walking was variable and unpredictable. One group of subjects performed against relatively low resistance, whereas another group performed against substantially greater resistance. In the low-resistance condition, no significant differences in CE, VE, time to target, or number of steps to target were found between any of the eight combinations of predictable or unpredictable resistances during walking. In the high-resistance condition, however, significant differences were found for CE and number of strides to target when resistance varied unpredictably during walking. Experiment 2 was similar in design but required subjects to walk with combinations of normal or short steps after they had viewed the target knowing only the gait type that would be used to begin locomotion. No differences in CE, VE, or time to target were found between four different combinations of gait type and predictability, under subjectively controlled conditions. When the step constraints were externally imposed, however, differences were found for CE. None of the results from either experiment, in which the number of strides needed to reach the target or the predictability of gait did not change from normal, supported the hypothesis that motor output requirements are necessary in forming a mental representation of the target position that can be used to walk to the target with eyes closed. Whichever locomotor technique was used to walk the estimated distance in these cases, the representation was able to be used independently. When walking mechanics were altered by externally imposed constraints, however, the success at reaching the estimated target position was reduced. These latter results are consistent with those obtained using up, down, and level walking and support the premise that mental representations used in blind walking are linked to the locomotor mechanics afforded by environmental conditions.     

The Clustering and Contagion of Suicide

Two general types of suicide cluster have been discussed in the literature; roughly, these can be classified as mass clusters and point clusters. Mass clusters are media related, and the evidence for them is equivocal; point clusters are local phenomena, and these do appear to occur. Contagion has not been conceptually well developed nor empirically well supported as an explanation for suicide clusters. An alternative explanation for why suicides sometimes cluster is articulated: People who are vulnerable to suicide may cluster well before the occurrence of any overt suicidal stimulus, and when they experience severe negative events, including but not limited to the suicidal behavior of one member of the cluster, all members of the cluster are at increased risk for suicidality (a risk that may be offset by good social support).     

The Effect of September 11th on Job Attribute Preferences and Recruitment

This paper considers the effects of the September 11^th attacks on job attribute preferences and recruiting strategies. A survey was conducted with firms (n = 46) and college students (n = 138) in the New York, New Jersey, and Pennsylvania area. Results indicate 91% of firms believe the attack changed the job attribute preferences of students. The corresponding survey given to college students indicates that 60% of the students say the attacks would not have an impact on their preferred job attributes.     

The Effect of Predicate Matching on Perceived Understanding and Factual Recall

Grinder and Bandler (1976) asserted that if therapists communicate with clients using verbal predicates that match the modality of the clients' primary representational system (PRS), it will be easier for the clients to understand the therapist and to believe that they are understood. In this study we investigated the relationship between predicate matching and understanding. Participants (N=99) listened to a recorded narrative under either a “matched” or “mismatched” experimental condition. Participants' objective understanding (factual recall) and subjective understanding (feelings of having understood) were assessed. The results weakly supported a claim of enhanced accuracy of understanding on one measure of objective understanding, and they suggested greater understanding and recall for visual PRS participants.     

Beyond Credentials: The Effect of Physician Sex and Specialty on How Physicians Are Perceived

The experiment investigated the effect of physician sex and specialty on participants’ perceptions of doctors. Participants (N = 206) viewed a physician profile (male/female orthopedic surgeon or male/female dermatologist) and then evaluated the physician on a survey. While male participants reported they would be more willing to see a female physician and believed female physicians would be more caring, female participants reported they would be more willing to see physicians in counter-stereotypical specialties and rated them as more caring. The study suggests that not only do men and women focus on different things in selecting physicians but also that negative stereotypes of female physicians have dramatically decreased.     

The Influence of Perceived Injustice on the Endorsement of Political Leaders1

Recent public opinion polls have suggested that there is a striking lack of public support for national political leaders and institutions. The two studies discussed in this paper explore why public evaluations of political leaders and institutions are low. In particular, they examine the role of perceived injustice in creating dislike for and distrust of leaders and institutions. This focus upon justice is contrasted with the more traditional focus upon the level of outcomes received from the political system and upon congruence in citizen-leader policy preferences. The results strongly support a focus upon justice by showing that judgments of injustice exercise an influence upon leadership evaluations and in stitutional endorsements which is independent of beliefs about the level of outcomes the political system is providing to citizens or of public support for government policies. In fact, both studies suggest that judgments of justice or injustice have more influence upon the endorsement of political leaders and institutions than do outcome-related concerns.     

Investigating Some Neglected Criteria: The Influence of Organizational Level and Perceived System Knowledge on Appraisal Reactions

Researchers have suggested that examining the factors which influence appraisal reactions is important because these reactions are critical criteria of appraisal effectiveness. The current field study investigates how organizational level and knowledge of the performance appraisal system may be related to employees' reactions toward the performance appraisal system. Inferences from past research suggest that supervisory employees' unique perspective on the appraisal system may lead to more positive evaluations. The present study attempts to better explain this relationship by investigating the effect of Perceived System Knowledge (PSK) as a mediator of this relationship. Results revealed that PSK completely mediated the relationship between organizational level and appraisal reactions.     

The Uncertainty Paradox: Perceived Threat Moderates the Effect of Uncertainty on Political Tolerance

People respond to dissimilar political beliefs in a variety of ways, ranging from openness and acceptance to closed‐mindedness and intolerance. While there is reason to believe that uncertainty may influence political tolerance, the direction of this influence remains unclear. We propose that threat moderates the effect of uncertainty on tolerance; when safe, uncertainty leads to greater tolerance, yet when threatened, uncertainty leads to reduced tolerance. Using independent manipulations of threat and uncertainty, we provide support for this hypothesis. This research demonstrates that, although feelings of threat and uncertainty can be independent, it is also important to understand their interaction.     

Perceived Symbols of Authority and Their Influence on Compliance1

There are many variables that influence compliance. With regard to individuals making requests of others, Bickman (1974) found that the apparel of the person making the request significantly influenced whether another person complied with the request. This study evaluates other factors such as sex, age, and altruism in compliance. Subjects were involved in a replication of Bickman's dime and parking meter study. Results showed that the dress of the perceived authority not only affected the number of subjects who complied but also the type of compliance, the type of noncompliance, and the latency between request and compliance. Also, older subjects complied significantly more often than younger subjects in the role authority condition.     

The Influence of Perceived Versus Aerobic Fitness on Psychological Health and Physiological Stress Responsivity

This study sought to evaluate the association between perceived and aerobic physical fitness and both psychological functioning and physiological stress responsivity. Sixty nonsymptomatic participants (30 males, 30 females) participated in the experiment. Participants completed a series of personality and mood questionnaires as well as a laboratory procedure measuring cardiovascular responses (i.e., heart rate and blood pressure) while performing stressful laboratory tasks (i.e., the Stroop Color Naming Test and a sham IQ test). Aerobic fitness (i.e., VO ₂ max using the Bruce protocol) as well as perceived fitness were also determined. Results suggest that perceived fitness was generally associated with positive personality and mood variables while aerobic fitness was not. Overall results support the view that perception of fitness may be as important or perhaps even more important than aerobic fitness in its association with psychological but perhaps not physical functioning.
