Effects of perception on public bike-and-ride: A survey under complex,multifactor mode-choice scenarios

Bicycles are an environmentally-friendly, energy-saving mode of transportation. Public bike-and-ride is a term used to describe the use of public bicycles combined with transit as a means of transportation. A new stated preference (SP) design scheme based on the factors respondents felt were most important was proposed to augment the traditional SP design under complex multi-factor and multi-level situations. iPads were used to automatically administer the survey under each design scheme and collect the choice behavior data for public bike-and-ride. The concept of perceived psychological distance was further proposed and used to estimate Logit models. Comparative analysis of these models shows for the traditional SP design scheme, some factors, including perceived psychological distance, have reduced statistically significant effects on public bike-and-ride choice relative to the new SP design scheme. This indicates that in scenarios with complex decisions, the decision-makers would reduce their consideration of some factors and simplify their decision process making the new SP survey design scheme more suitable to analyze their choice behavior in those cases. Model analysis showed that perceived psychological distance for each traveler is the most critical factor during the decision process for travel behavior analysis. Finally, sensitivity analysis was conducted to determine which factors in the new survey design were important to increase the share of public bike-and-ride users. Practical findings for promoting public bike-and-ride use are presented in addition to theoretical references for improving the traditional survey methods.     

Accounting for the Theory of Planned Behaviour in departure time choice

Motivating people to change their departure time could play a key role in reducing peak-hour congestion, which remains one of the most prevalent transport problems in large urban areas. To achieve this behavioural change, it is necessary to better understand the factors that influence departure time choice. So far departure time choice modelling focussed mainly on objective factors, such as time and costs as main behavioural determinants. In this study, we derived psychological factors based on the Theory of Planned Behaviour, estimated them based on structural equation modelling, and included them into a discrete choice model. The psychological factors were measured based on an online questionnaire addressed to car commuters to the city centre of Copenhagen (N = 286). The questionnaire additionally included a travel diary and a stated preference experiment with nine departure time choice scenarios. All psychological factors had a significant effect on departure time choice and could improve the model as compared to a basic discrete choice model without latent constructs. As expected, the effects of the psychological factors were different depending on framework conditions: for people with fixed starting times at work, the intention to arrive at work on time (as estimated by subjective norm, attitude, perceived behavioural control) had the strongest effect; for people with flexible working hours, the attitude towards short travel time was most relevant. Limitations, the inclusion of additional psychological factors and their possible interactions are discussed.     

Behavioral shifts after a fatal rapid transit accident: A multinomial logit model

The Washington, DC Metrorail collision in 2009 presents a rare opportunity to study rapid transit passengers’ responses to a highly publicized rail incident entailing injuries and fatalities. To investigate behavioral responses to the accident, particularly mode shifts, we conducted a web-based survey of approximately 300 commuters traveling on Metrorail after the accident who had used Metrorail in the 6 months prior to the collision. The most common response to the accident was avoidance of the first and last train cars. Some respondents substituted some Metrorail trips with other modes or took fewer Metrorail trips. To investigate factors influencing these behavioral responses, we employ multinomial logit models to explore the statistical association between respondent and travel characteristics and the choice among the options of (1) making no changes, (2) avoiding certain seating locations, (3) changing modes of transportation, and (4) changing both seating locations and modes of transportation. Results suggest that travel inertia, specifically mode inertia, exists, in that respondents generally prefer not to make mode or travel choice changes. However, some mode characteristics, such as cost differences and frequent delays have a statistically significant association with mode switching. Gender and the presence of children in the household correlate with the option selected.     

Staying on or getting off the sidewalk? Testing the Mehrabian-Russell Model on pedestrian behavior

Social and environmental psychology provide a variety of models based on which to understand how built environments can elicit people’s behavioral responses. The Mehrabian-Russell model (MRM), initially presented in 1974, provides a framework that explains avoid–approach behavior towards a place based on a primary emotional response (PER) and affective states elicited by the perceived stimuli from the environment. However, despite the potential applications of the MRM in travel behavior studies, traditional models (e.g., discrete choice models and integrated choice latent variable) do not incorporate this specific psychological process that converts environmental stimuli into behavioral responses. Hence, this paper aims to test the applicability of MRM to urban sidewalks. To fulfill this objective, we developed a two-level structural equation model using latent variables (LV) identified from a confirmatory factor analysis (CFA) based on 1056 in-person surveys on 30 different sidewalks in Bogotá, Colombia. We then evaluated the effect of the PER on declared avoidance as a proxy of behavioral intention. The CFA uncovered three LV equivalent to the three affective dimensions of the MRM—arousal, pleasure, and dominance—followed by a fourth LV, representing the PER, which explains the three previous LVs. This confirms the applicability of these kinds of psychological and environmental models in pedestrian behavior evaluation. We found that PER can explain the declared intention of avoidance towards the sidewalk in an urban setting. Proving that this kind of model can explain the way in which the built environment can elicit pedestrians’ emotional responses and subsequent behaviors, provides information that can be used as input in travel behavior studies focusing on the promotion of active traveling and mode change.

Non-Ideal Virtue and Situationism

Several philosophers, known as situationists, have argued that evidence in social psychology threatens to undermine Aristotelian virtue ethics. An impressively large amount of empirical evidence suggests that most people do not consistently act virtuously and lack the ability to exercise rational control over their behavior. Since possessing moral virtues requires these features, situationists have argued that Aristotelianism does not accurately describe the character traits possessed by most people, and so the theory cannot lay claim to various theoretical advantages such as explanatory power and egalitarian character education. In contrast to previous defenses which either downplay the relevance of psychological evidence or revise philosophical conceptions of virtue to fit the data, this paper appeals to previously neglected psychological evidence on self-efficacy and mental contrasting in combination with “non-idealized” interpretations of Aristotelian moral virtue to support the view that the available empirical evidence is compatible with widespread possession of virtuous character. These “non-idealized” interpretations of virtuous character allow for serious deviations from virtuous conduct, especially in the contexts described by the psychology experiments. Furthermore, decades of research on mental contrasting and self-efficacy suggest that subjects in the psychology experiments acted for reasons and possessed the ability to exercise rational control over their behavior. Hence, situationists are mistaken in thinking that, based on the empirical data, Aristotelianism is deprived of various theoretical advantages.

     

Unresolved questions in nudging research: Putting the psychology back in nudging

Nudging interventions are broadly defined as a rearrangement of a choice context that gently suggests a specific choice. Their increasing popularity has attracted attention and discussion from researchers, policy makers, and practitioners alike. After some applications to domains such as health, environmental issues, and retirement savings, the next step in nudging is to understand the psychological boundary conditions when applied to varied domains of daily life. It is yet unclear for example to what extent nudging interventions can be transparent without losing effectiveness, or how permanent the effects are. These unresolved questions may have contributed to heated political and scientific discussions, on for example the ethics of using nudges in the public health domain, due to the missing scientific evidence. Indeed, this popularity may have led to forget how nudging harnesses insights from decades of research in psychology to change people's behavior. The aim of this paper is to shift the focus back to the psychological premises nudges were built upon. It summarizes several outstanding questions that future research in the psychology of nudging should address. Advancing research in nudging will help to improve our understanding of applied nudging interventions and provide clarity to debates such as ethical appropriateness, effectiveness, and public approval.     

Commuting by car or public transportation? A social dilemma analysis of travel mode judgements

The current paper analyses judgements regarding the decision to commute by car versus public transportation in terms of a conflict between immediate self-interest and long-term collective interest (i.e. social dilemma). Extending traditional formulations of rational choice theory, the present study revealed that preferences for public transportation (i.e. the presumed cooperative option) in a standard commuting situation were enhanced not only by the belief that public transportation provided a shorter average travel time than car (i.e. the presumed noncooperative option), but also by the belief that public transportation was at least as reliable (i.e. an equal or lower variability in travel time compared to car). Moreover, paralleling prior research on experimental social dilemmas, preferences were found to be affected by a pro-social concern—the belief regarding the impact of cars on the level of environmental pollution. Our findings indicated that any combination of two such considerations (i.e. travel time, variability, and impact of cars on pollution) was m ore effective in promoting public transportation preferences than the sum of their separate effects. Finally, we obtained evidence that commuter preferences were also shaped by individual differences in social value orientations (i.e. preferences for patterns of outcomes for self and others) in that, relative to pro-self commuters, pro-social commuters exhibited greater preference for public transportation.     

Exploring the interactions between modal options,destination access,and travel mood

A good understanding of subjectively experienced well-being in daily travel is critical for the design and evaluation of transportation policies and programs. Numerous studies have examined the relationship between how we travel and how we feel during travel. However, people’s travel mood is not only determined by their trip characteristics but also their potential mobility—the capacity of being mobile. Using the data collected via a smartphone application in Minneapolis-St. Paul area, we measure potential mobility in two aspects—modal options and destination access and reveal that people in households with better access to cars and alternative transportation modes are, all else equal, more likely to report more positive moods and fewer negative moods during travel. In addition, people living in neighborhoods with greater access to destinations are less likely to feel stress when traveling. We also find that associations between mode and mood are moderated by modal options and destination access. These findings confirm the importance of explicitly considering modal options and destination access in policy debates and planning initiatives addressing transportation and well-being. In doing so, they demonstrate the relevance of Sen’s Capabilities Approach to transportation planning.     

The effects of option framing on consumer choices: Making decisions in rational versus experiential processing modes

• In the marketplace, consumers often encounter framed scenarios for optional product features, whereby they can add desired product options to a base model or delete undesired product options from a fully loaded model. The results of two experiments show that such option framing can influence consumers' decision making regarding the total number of finally chosen product options. Also, consumers' processing modes – rational versus experiential, can influence their choice behavior under option framing. Specifically, consumers choose a higher number of options in the delete (versus add) frame, and the effect is magnified when making decisions in an experiential mode, and it is diminished when making decisions in a rational mode. Moreover, cognitive constraints further moderate these effects.

Psychology as the Science of Self-Reports and Finger Movements: Whatever Happened to Actual Behavior?

ABSTRACT— Psychology calls itself the science of behavior, and the American Psychological Association's current "Decade of Behavior" was intended to increase awareness and appreciation of this aspect of the science. Yet some psychological subdisciplines have never directly studied behavior, and studies on behavior are dwindling rapidly in other subdisciplines. We discuss the eclipse of behavior in personality and social psychology, in which direct observation of behavior has been increasingly supplanted by introspective self-reports, hypothetical scenarios, and questionnaire ratings. We advocate a renewed commitment to including direct observation of behavior whenever possible and in at least a healthy minority of research projects.     

Constructs to describe individual knowledge / Constructos para describir el conocimiento individual

Abstract

The basic unit of any cognitive model that attempts to describe individual knowledge and its manifestations must be chosen carefully, as the resulting position on learning, teaching and, in general, of the psychological research subject depends largely on this choice. The objective is to assess and contrast two constructs of enormous significance in cognitive psychology that have been used as cognitive units under different theoretical contexts: the concept in its classical sense, and the scheme in its organismic version. Arguments are presented to show that the latter is more consistent with constructivist assumptions and is more respectful of psychological data such as the Gestalt and prototype effects or the existence of procedural and implicit knowledge.

Measurement and decision making at the University of Michigan in the 1950s and 1960s

This article explores the emergence of Clyde Coombs' mathematical psychology and Ward Edwards' behavioral decision research at the University of Michigan in the 1950s and 1960s. It shows why and how the mathematical psychological focus on the mathematics of measurement neatly complemented the experimental work on rational human decision making of the behavioral decision researchers. Both understood measurement as the rational decision of a human being between two or more stimuli, or values, and viewed the experimental measurement of actual human decision behavior as a key objective of psychology. For both “measurement theory in psychology [was] behavior theory.” © 2010 Wiley Periodicals, Inc.     

Choice/Matching Preference Reversals in Groups: Consensus Processes and Justification-Based Reasoning

Individual preferences can vary significantly by the mode in which they are elicited. Thus, the seemingly benign procedural issue of elicitation mode (i.e., choice, buying price, rating, matching) could have a profound effect on group decisions, although elicitation mode has not been much studied as a group procedural variable. Individual preferences differ by elicitation mode when the elicitation contexts differentially emphasize particular aspects of the decision. Emphasis on explainability, for example, may produce decisions that are based only on a few, important, attributes. Because group consensus processes also can encourage particular reasoning strategies, grouping may interact with elicitation mode; that is, group consensus processes may moderate or exacerbate preference reversals. The present study explored a particular elicitation effect, choice versus matching preference reversals, for decisions with both low and high social significance. The results confirmed both that elicitation mode can affect group decisions and that group consensus processes moderate choice/matching preference reversals. Further, evidence from both preference measures and rating scales suggested that the moderation was due to an increase in easily defended, justifiable decisions. Social significance did not affect individual or group decisions, but decreased members′ post group commitment to the group decision. These results have implications both for group decision making and for the study of the role of explanation-based strategies in preference formation.     

Tomorrow I’ll be me: The effect of time perspective on the activation of idealistic versus pragmatic selves

It is widely accepted that the self-system is dynamic and consists of multiple selves that emerge under different contexts. The present research describes two types of diverging self-conceptions, the idealistic and pragmatic selves. Building on a synthesis of construal level theory with research on the self, we propose that a more distal time perspective activates an idealistic versus a pragmatic self. Self-activation, in turn, influences the preference between two major motives: maximizing identity versus instrumental benefits. A series of five studies supported this conceptualization by demonstrating that: (a) distal rather than proximal time perspective enhances the preference for identity over instrumental benefits; (b) people construe themselves as relatively more idealistic than pragmatic when primed with a distal than proximal time perspective, and (c) self-activation mediates the effect of time perspective on preference. The studies also investigate boundary conditions and process measures that shed light on the interface between time, self, and preference. The final section discusses the theoretical implications for the literatures on construal level, self, and justice and the practical implications for organizational behavior, political psychology, and human decision-making.     

Dimensional comparisons: Much is known about the effects,less about the processes

Dimensional comparisons are comparisons between different domains. They are well known in educational psychology. Here, they explain the seemingly paradoxical finding that students' math and verbal self-concepts of ability usually show correlations close to zero, although students' math and verbal achievements show strong positive correlations. This finding can be explained by the fact that students overemphasize potential differences between their math and verbal achievements when they form their self-concepts. However, dimensional comparisons also take place and affect self-evaluations outside the educational context, and the number of studies examining dimensional comparisons in different contexts has significantly increased during the last few years. This paper provides an up-to-date overview of findings on dimensional comparisons. It presents findings from studies that have examined effects of dimensional comparisons (as most studies dealing with dimensional comparisons have done so far), as well as studies that have focused on an understanding of the psychological processes involved in dimensional comparison (which relatively few studies have done so far). It is hoped that this paper will help broaden awareness of dimensional comparisons and stimulate further research on this type of comparison, especially in disciplines other than educational psychology.     

The Fire Chief microworld generating program: An illustration of computer-simulated microworlds as an experimental paradigm for studying complex decision-making behavior

Computer-simulated microworlds bridge the gap between the complexity of field investigations and the rigor of laboratory studies. The purpose of this paper is to draw attention to the major methodological issues involved in developing and using computer-simulated microworlds for the psychological study of complex decision-making behavior. These issues comprise flexibility and generality in the microworlds that can be created, adequate psychological validity, automatic trial administration and data logging, capacity to interface simulations of psychological processes, and adequate testing and documentation. Each of these issues is illustrated by indicating how it has been addressed in Fire Chief, a microworld generating program specifically designed for creating realistic, yet controllable, decision-making task environments in the psychology laboratory. Fire Chief (Omodei & Wearing, 1993a) is introduced as both fully portable to other research teams and suitable for use in many different contexts requiring a complex task situation.
