Identifying the Distress Cues that Influence Support Provision: A Paired Comparison Approach

ABSTRACT

Just as chemistry has methods for determining the composition of unknown substances, psychology needs, but has lacked, effective methods for identifying the “active ingredients” of social stimuli. We describe such a method and apply it to identify the verbal and nonverbal distress cues that serve as signals prompting others to provide social support. This method allowed us to identify 55 such cues. Furthermore, the cues that were salient in the minds of potential support providers depended on their goals. For example, when deciding whether someone needed support, negative nonverbal cues (e.g., distressed persons' fidgeting) were more salient, but when deciding whether one was willing to provide support, cues that suggested a positive outcome for the support seeker (e.g., distressed persons' positive attitude and open-mindedness) were more salient.     

Disjunction Between Probability and Verdict in Juror Decision Making

Although the law assumes a close relation between the probability that a defendant committed the act in question and the ensuing verdict of the jurors, prior research has shown this assumption to be often violated. We present five experiments designed to show that factors that influence probability also influence verdict, but other factors are capable of directly producing changes in verdict without affecting probability. In Experiment 1, we replicated the Wells Effect; scenarios generating the same probability that the Blue Bus Company was to blame for the same accident, nevertheless, generated significantly different likelihoods of finding the defendant liable. In Experiment 2, we showed that equally diagnostic affirmative and negative evidence had differential effects on mock jurors' probability estimates and verdicts. In Experiment 3, we showed that a completely nondiagnostic witness, who either implicates the same bus company or a different bus company as did a diagnostic witness, significantly influenced mock jurors' verdicts. However, the nondiagnostic witness did not change the probability that the Blue Bus Company was responsible for the accident. In Experiment 4, we demonstrated that base rate and witness reliability information resulted in very similar probability estimates but radically different verdicts. In Experiment 5, we showed that a change in the diagnosticity of the evidence influenced both probability and verdict with the former mediating differences in the later. Because probability is only one of the several determinants of the verdict, the two dependent variables are not as closely related as the law presumes. Copyright © 2011 John Wiley & Sons, Ltd.     

Externalities Awareness in Anticommons Dilemmas Decreases Defective Behavior

The present paper explores the effect of the salience of collective consequences of opportunistic behavior in commons and anticommons dilemmas. Making this type of externalities salient was expected to increase the awareness of the conflict between collective and personal interests, especially in the anticommons dilemma. The results of a vignette study (Study 1, N = 100) and a laboratory experiment (Study 2, N = 55) confirmed our hypotheses, revealing more opportunistic behavior in the anticommons than in the commons dilemma when externalities were not made salient, while no significant dilemma effect was obtained when the externalities were made salient. Moreover, the results of Study 2 demonstrated that the dilemma effect on cooperation was mediated by externalities awareness. The positive effects of increments in externalities awareness on cooperation are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

To deliberate or not to deliberate: Interactions between age,task characteristics,and cognitive activity on decision making

The effects of aging and deliberative activities on decision making were examined. In two separate tasks, young, middle‐aged, and older adults were presented with four alternatives and given instructions to choose the best one. Following study, participants were either given additional time to think about their decision or were prevented from doing so. Decision quality did not benefit from additional deliberative activity when the structure of the stimuli facilitated fluent online processing. In contrast, deliberation promoted performance when such processing was more difficult. In addition, those individuals who focused on attribute information relevant to the decision context performed better than those who did not. Age differences in performance were minimal, but older adults with lower levels of education or cognitive ability tended to perform worse than the rest of the sample under conditions where deliberative skills were required to promote performance. The results are inconsistent with recent proposals regarding the benefits of passive deliberation. In addition, the results support the general assertion that the age effects in decision making will be most evident in situations dependent upon deliberative skills.

Cautious behaviors of pedestrians while crossing narrow streets: Exploration of behaviors using virtual reality experiments

This study explores the cautious behaviors of pedestrians in a typical local street environment using virtual reality (VR)-based experiments under various physical safety design scenarios for roadways. The built environment of this study focused on narrow local roads where frequent daily walking occurs within a neighborhood. VR experiments can provide an objective and accurate measurement of pedestrian behaviors, thus improving the understanding of complicated pedestrian behaviors. Based on experimental data from 200 university students, we identified pedestrians’ crossing behavior that is cautionary or risky concerning various physical safety designs of streets. This study found that there are trade-off relationships between various behaviors which should be systematically studied to produce safer street design guidelines. Furthermore, as the contexts and sequences matter in behaviors for intersection crossing, the interpretation of behaviors should carefully consider the context of built environments and sequential decisions made by pedestrians. This sequential understanding of before- and during-crossing behaviors and their connections expands our knowledge of pedestrians’ crossing behaviors.     

More Rational or More Emotional Than Others? Lay Beliefs About Decision-Making Strategies

Research demonstrates that people utilize both reasoning and feeling in decision making and that both strategies can be advantageous. However, little is known about how people perceive their decision-making relative to others. Despite research findings and popular appeals supporting the use of affective decision processes, across a series of studies, we find that individuals believe they rely more on reasoning, and less on feelings, than others. These effects are driven by the motivation to self-enhance where, in most contexts, individuals believe the use of reasoning is superior, and self-enhancing, compared to the use of feelings. Consistent with this mechanism, beliefs that one’s decisions are more rational than others’ are as follows: (a) stronger for those who exhibit greater beliefs in the superiority of reasoning (vs. feeling), (b) attenuated when the decision context precludes motivational thinking about the self or the self is affirmed, and (c) reversed when the use of feelings is perceived as more self-enhancing. We demonstrate downstream consequences (e.g., decision delegation), rule out alternative explanations, and discuss practical implications of these lay beliefs.     

Better to Decide Together: Shared Consumer Decision Making,Perceived Power,and Relationship Satisfaction

Shared consumer decisions, particularly those made with a relationship partner, can be very different from decisions that are made alone. Across multiple studies, we investigate how shared consumer decision making affects perceptions of power and relationship satisfaction. We integrate two streams of research to create a novel theory about consumer decision making and perceived power. Specifically, we suggest that shared consumer decision making combines two necessary components of power—an individual's influence over and a partner's engagement in the decision—and that these combined components drive power perceptions. In other words, individuals who relinquish some control and make a decision with their partner, ironically, perceive having greater power than if they had made the decision alone. We further find that shared decision making and greater perceived power lead to greater satisfaction with the relationship in which the decisions are made. By focusing on consumer decision making within relationships, the current research contributes to the literatures on decision making, social influences in consumer behavior, close relationships, consumer well-being, and power.     

Impact on driver behaviour of guardrails of different height in horizontal-vertical coordinated road scenarios with a limited available sight distance

Drivers consider traffic barriers (e.g., guardrails) a protection system, a hard obstacle and a sight obstruction. Hence, the possibility of using containment level barriers which are higher and superior than the minimum required by current standards should be carefully evaluated. Moreover, research investigations into their impact on driver behaviour should be designed so as to distinguish between the effects associated with each of the three roles cited above.This driving simulation study investigates how drivers adapt their longitudinal and transversal behaviour when negotiating curves with guardrails of different heights on horizontal-vertical coordinated two–lane rural road settings, with consideration given solely to the sight obstruction effect of the guardrails. Fifty-four participants drove four out of the eighteen possible scenarios obtained when the same horizontal alignment is combined with three vertical profiles with three inner roadside treatments (no guardrails, 0.75 m two–wave and 0.95 m three-wave guardrails) and the two driving directions.Research outcomes confirm that guardrail height has a significant impact on lateral and longitudinal behaviour. With the minimum standard, i.e., the minimum height, drivers stay closer to the roadside, while higher guardrails result in drivers increasing their lateral distance. Speeds are influenced by the interaction between the guardrail and other geometric and human factors. Male and female drivers adapt differently to the limitation in the available sight distance caused by the guardrail: males increase their speed, adopting a more aggressive behaviour than females. Important safety implications due to the higher speeds and wider trajectories have to be considered at the design stage.
