Drivers discuss ecodriving feedback: Goal setting,framing, and anchoring motivate new behaviors

Ecodriving, defined here as the adoption of energy efficient driving styles and practices (primarily moderating accelerations and decelerations, reducing top speeds, and improved maintenance practices), has long been recognized as a potential source of reductions in transportation energy use. Estimates of energy savings attributed to ecodriving range widely, from less than 5% to as high as 20% depending on the driving and experimental context. To explore the effects on ecodriving of interaction between drivers and in-vehicle energy feedback, a customized, interactive energy feedback interface was deployed in a field test with real-world drivers. This paper presents the results of interviews with 46 Plug-in Hybrid Electric Vehicle (PHEV) drivers who were given the ecodriving feedback interface for a multi-week trial including an interface off (baseline) and on (treatment) condition. This paper relies specifically on self-reports of driver motivations and behaviors to better understand what types of information motivated new ecodriving behavior; a future paper will investigate quantitative fuel consumption effects. Driver interviews at the conclusion of the study revealed that the introduction of feedback led three fourths of drivers to change driving styles to maximize on-road efficiency, at least in the short term. In addition, this study finds that the context of the feedback information, provided by a built-in goal or other contextualizing information such as a comparison value, is important for both comprehension and motivation. Personalization of the information allowed different drivers to access pertinent information, increasing the motivational value of the information. Instantaneous performance feedback such as real-time energy economy or power is used primarily for experimentation and learning of new ecodriving behaviors, whereas average performance feedback is used primarily for goal-setting and goal achievement. In addition, the direct comparison of personalized driver goals and average performance created a game-like experience that encouraged high achievement. Finally, the driver interviews revealed that feedback frames driving as a time to act in an efficient manner.     

Towards consensus in conceptualizing and operationalizing physical activity maintenance

Recognized challenges in promoting long-term physical activity maintenance may be due to inconsistencies in the conceptualization and operationalization of behavior maintenance terminology in physical activity research. The overall goal of this paper is to propose a framework and agenda for the development of a common set of terms, definitions, and measures for physical activity maintenance concepts that can be widely tested and evaluated. To initiate this effort, this paper (1) provides an overview of conceptual and operational definitions of physical activity maintenance used in the empirical literature, (2) evaluates whether behavior maintenance terms used in addiction science can be translated to physical activity, (3) recommends research directions for developing consensus definitions of physical activity maintenance, and (4) proposes a conceptual model of physical activity maintenance with inflection points that require operational definitions to be decided upon through consensus efforts in the field. Consensus over the conceptualization and operationalization of physical activity maintenance is needed to draw conclusions regarding which policies and programs are best able to promote long-term behavior change.     

Theistic Ethics and the Euthyphro Dilemma

It is widely believed that the Divine Command Theory is untenable due to the Euthyphro Dilemma. This article first examines the Platonic dialogue of that name, and shows that Socrates's reasoning is faulty. Second, the dilemma in the form in which many contemporary philosophers accept it is examined in detail, and this reasoning is also shown to be deficient. This is not to say, however, that the Divine Command Theory is true—merely that one popular argument for rejecting it is unsound. Finally some brief thoughts are presented concerning where the real problems lie for the theory.     

Measuring the mental

Many philosophers have argued that the subjective character of conscious experience results in a fundamental deficit of third-person (henceforth: extrospective) access to first-person experience. By comparing extrospective measurement techniques with measurement techniques in the natural sciences, we will argue that extrospective methods suffer from no such deficit.After a rejection of some principled objections against extrospective methods, a historical comparison with the development of measurement techniques in the natural sciences will show that extrospective measuring methods are still in an early stage of development. However, they can be significantly improved by way of a bootstrapping strategy, similar to that which has proven successful in the development of physical measurement techniques. One reason to expect such improvement is the availability of multiple sources of evidence, which should allow for substantial advances in extrospective measurement techniques. Finally, we will discuss new developments in pain measurement in order to show that the bootstrapping strategy is already bearing fruit.     

Factorial structure of the ‘ToM Storybooks’: A test evaluating multiple components of Theory of Mind

This study examined the factorial structure of the Theory of Mind (ToM) Storybooks, a comprehensive 93‐item instrument tapping the five components in Wellman's model of ToM (emotion recognition, understanding of desire and beliefs, ability to distinguish between physical and mental entities, and awareness of the link between perception and knowledge). A sample of 681 three‐ to eight‐year‐old Italian children was divided into three age groups to assess whether factorial structure varied across different age ranges. Partial credit model analysis was applied to the data, leading to the empirical identification of 23 composite variables aggregating the ToM Storybooks items. Confirmatory factor analysis was then conducted on the composite variables, providing support for the theoretical model. There were partial differences in the specific composite variables making up the dimensions for each of the three age groups. A single test evaluating distinct dimensions of ToM is a valuable resource for clinical practice which may be used to define differential profiles for specific populations.     

The Effects of Accumulated Underaccommodation on Perceptions of Underaccommodative Communication and Speakers

This study examined the effects of repeated instances of underaccommodation (i.e., insufficiently adjusted communication) on people's perceptions and evaluations of communication and speakers. Participants (N = 179) completed a series of three map‐based tasks that required them to follow directions that contained insufficient information. Consistent with hypotheses, as underaccommodation accumulated across tasks, participants inferred less positive motives for the speaker's communication, and inferences about motive for each task contributed directly and indirectly to overall evaluations of both the speaker and their communication. These results indicate that accumulated underaccommodation is consequential, and underscore the theoretical importance of motive attributions to predicting reactions to underaccommodation.     

Opinion Climates in Social Media: Blending Mass and Interpersonal Communication

Social media's capacity for users to generate, comment on, and forward content (including mass media messages) to other users has created new forms of mass interpersonal communication. These systems render observable processes underlying the formation of opinion climates. Five attributes of contemporary electronic opinion environments can alter the way users gauge, form, and express opinions on topics of public interest: the juxtaposition of mass media and user‐generated content, ideological homogeneity and heterogeneity of online networks, technical ease with which to express opinions, the reach of messages, and networked audiences. These attributes facilitate analysis of theoretical and empirical works from different scholarly traditions, suggesting lines of inquiry that can enrich the analysis of (public) opinion formation via current communication technologies.     

Power and Effectiveness: Envisioning an Alternate Paradigm

SUMMARY

Relational-Cultural Theory provides a straightforward and elegant definition of power; it is the capacity to produce change. The implication of this framework is that power is the energy of competence in everyday living. However, in a culture stratified along multiple dimensions-race, class, and sexual orientation to name a few–power is associated with hyper-competitiveness and deterministic control. The article begins by examining the “protective illusions” of the power-over paradigm, where humanity is rank ordered according to perceived cultural value and is stratified into groups of greater than and less than. In addition to exposing the false dichotomies of power-over arrangements, the article examines the destructive consequences of cultural disconnection, on both the putative winners and the losers. Examples from organizational practice, clinical relationships, and socio-political contexts are used to illustrate the Relational-Cultural Model in action. Specifically, scenarios are presented from the standpoint of the politically disempowered to demonstrate the relational competencies of empathic attunement, authenticity, and accountability that foster healing, resilience, and mutual empowerment.
