Evidence that implementation intentions reduce drivers’ use of mobile phones while driving

Implementation intentions are IF-THEN plans that have the potential to reduce mobile phone use while driving and thus contribute towards the prevention of road traffic crashes. We tested whether an intervention, designed to promote the formation of implementation intentions, could reduce drivers’ use of mobile phones. A randomized controlled design was used. The participants (N = 136) were randomised to an implementation intention or a control condition. Self-report questionnaires were administered to all participants at both pre- and one-month post-intervention to measure the use of mobile phones while driving, goal intentions and the theoretically derived motivational pre-cursors of goal intentions (attitudes, subjective norm and perceived behavioural control). Immediately following the pre-intervention questionnaire, the participants in the implementation intention condition (n = 67) were given a volitional help sheet, which asked them to form implementation intentions by specifying target driving situations that tempted them the most to use a mobile phone and linking them with goal-directed responses that could be used to resist the temptation. The participants in the control condition (n = 69) were asked to specify target situations that tempted them the most to use a mobile phone while driving and to generally try to avoid using a mobile phone in those situations. One-month post-intervention, the participants in the implementation intention condition reported using a mobile phone less often while driving in their specified target driving situations than did the participants in the control condition. As expected, no differences were found between the conditions in the reported frequency of mobile phone use in unspecified driving situations, goal intentions or any motivational pre-cursor of goal intentions. The implementation intention intervention that was tested in this study is a potentially effective tool for reducing mobile phone use while driving in target driving situations, where behaviour-change is most needed.     

Moral migration: Desires to become more empathic predict changes in moral foundations

Many people want to change their personality traits—and research on volitional change has documented their success in doing so. In the present study, we examine whether people also wish to change their levels of empathy, and whether these desires precede shifts in dispositional empathy and morality over a 15-week period. We recorded participants’ change goals, followed by weekly measurements of empathic concern and perspective-taking, as well as moral foundations. Results indicated that most participants wished to cultivate empathic concern and, especially, perspective-taking. Those who sought to develop these qualities tended to actually do so at a faster rate than their peers who did not—and, as a consequence, also drifted toward a characteristically liberal, individualizing morality.     

Is inhibition of return a reflexive effect?

The inhibition of return (IOR) phenomenon is routinely considered an effect of reflexive attention because the paradigm used to generate IOR employs peripheral cues that are uninformative as to where a target will appear. Because the cues are spatially unreliable it is thought that there is no reason for attention to be committed volitionally to them, and hence, the IOR effect is considered reflexive. What has been generally overlooked, however, is that the cues provide reliable temporal information as to when a target will occur. This predictive information is used by participants to prepare volitionally for when a target is likely to appear. We investigated whether the IOR effect is a product of the volitional application of attention to peripheral cues for the use of their temporal information. To test this idea we rendered the temporal information provided by peripheral cues unreliable. While this eliminated participants using the cues volitionally, it did not abolish the IOR phenomenon. These data demonstrate two new findings. First, the IOR effect is fundamentally a reflexive phenomenon. Second, when peripheral cues are not used volitionally, the IOR effect is attenuated. Together, the present findings indicate that the IOR effect can be modulated by volitional (top-down) processes but it is not the product of them. We argue that an intimate link between fronto-parietal regions and the superior colliculus provide a functional neural mechanism for this volitional effect to impact IOR.     

Testing the theory underlying the success of point-of-choice prompts: A multi-component stair climbing intervention

Objectives

Point-of-choice prompts consistently increase stair climbing in public access settings. This study investigated the single and combined effects of a volitional and motivational component of a stair climbing intervention to test the theory underlying the success of point-of-choice prompts.

Design

Quasi-experimental, interrupted time series cross-over design.

Methods

Ascending stair/escalator choices were observed in a UK tram station (n = 38,187). Baseline observations (2 weeks; stage 1) preceded a 2-week point-of-choice prompt positioned alone (stage 2) followed by an additional message positioned at the top of each climb (6 weeks; stage 3). Four weeks after message removal, another baseline (2 weeks; stage 4) preceded installation of the intervention components in reverse order. Thus, the message positioned alone at the top of each climb (4 weeks, stage 5) was supplemented with the point-of-choice prompt (2 weeks, stage 6). Logistic regression analyses of stair/escalator choice included the independent variables of intervention components, gender, time of morning and pedestrian traffic volume.

Results

There was no change in stair climbing percentages when only one intervention component was used, i.e. only the point-of-choice or the message at the top of each climb. In contrast, stair climbing increased when both components of the intervention were installed. Additionally, men took the stairs more than women and stair climbing was more common earlier in the morning and at higher pedestrian traffic volumes.

Conclusions

A motivational component targeting intentions increased the effectiveness of a volitional point-of-choice prompt for stair climbing in a setting where choice of the stairs incurred a time penalty for pedestrians due to the site layout.

Rethinking volitional control over task choice in multitask environments: Use of a stimulus set selection strategy in voluntary task switching

Under conditions of volitional control in multitask environments, subjects may engage in a variety of strategies to guide task selection. The current research examines whether subjects may sometimes use a top-down control strategy of selecting a task-irrelevant stimulus dimension, such as location, to guide task selection. We term this approach a stimulus set selection strategy. Using a voluntary task switching procedure, subjects voluntarily switched between categorizing letter and number stimuli that appeared in two, four, or eight possible target locations. Effects of stimulus availability, manipulated by varying the stimulus onset asynchrony between the two target stimuli, and location repetition were analysed to assess the use of a stimulus set selection strategy. Considered across position condition, Experiment 1 showed effects of both stimulus availability and location repetition on task choice suggesting that only in the 2-position condition, where selection based on location always results in a target at the selected location, subjects may have been using a stimulus set selection strategy on some trials. Experiment 2 replicated and extended these findings in a visually more cluttered environment. These results indicate that, contrary to current models of task selection in voluntary task switching, the top-down control of task selection may occur in the absence of the formation of an intention to perform a particular task.     

Deflecting Arrow by Aggregating Rankings of Multiple Correlated Criteria According to Borda

This paper has two objectives. The first is to review and address concerns raised by Hazelrigg that Arrow's impossibility theorem prevents the selection of rational aggregation methods for use in engineering trade studies. In addressing these concerns, the work of Saari is cited to establish the fact that the Borda count is the only ‘non‐dictatorial’ positional voting method that satisfies the criteria for a rational decision procedure while using complete information. Hence, the resulting rank ordering of the alternatives is the most reliable outcome. Several previous studies that use other aggregation methods are critiqued, and Borda is applied to examples to illustrate the differences in the outcomes. The second objective is to extend the applicability of Borda to include attributes such as cost, schedule duration, and certain technical and performance measures that are generally more reasonably described as correlated random variables. Exact Probabilities by Simulation with Borda, a method introduced by Hulkower that improves a technique by Book for determining which candidate in a trade study is the probable lowest‐cost alternative, is generalized to include multiple correlated criteria, each of which is expressed as a random variable and thus incorporates probabilistic uncertainty.

Imaginability,morality, and fictional truth: dissolving the puzzle of ‘imaginative resistance’

This paper argues that there is no genuine puzzle of ‘imaginative resistance’. In part 1 of the paper I argue that the imaginability of fictional propositions is relative to a range of different factors including the ‘thickness’ of certain concepts, and certain pre-theoretical and theoretical commitments. I suggest that those holding realist moral commitments may be more susceptible to resistance and inability than those holding non-realist commitments, and that it is such realist commitments that ultimately motivate the problem. However, I argue that the relativity of imaginability is not a particularly puzzling feature of imagination. In part 2, I claim that it is the so-called ‘alethic’ puzzle, concerning fictional truth, which generates a real puzzle about imaginative resistance. However, I argue that the alethic puzzle itself depends on certain realist assumptions about the nature of fictional truth which are implausible and should be rejected in favour of an interpretive view of fictional truth. Once this is done, I contend, it becomes evident that the supposed problem of imaginative resistance as it has hitherto been discussed in the literature is not puzzling at all.

Beyond the representation field

Abstract

This article outlines the importance of representation and several Freudian concepts such as Vorstellung, Trieb, and word and object representations. The author refers to the division of the analytical process into two main fields: the field of representation, and the field of the Real, which is characterized by impossibility. He then states that this field is the proper field of psychoanalysis. The author presents two clinical vignettes in an attempt to demonstrate the significance of the analytical act as a tool to deal with such extreme psychic situations.
