Exploring the acceptance of connected and automated vehicles: Focus group discussions with experts and non-experts in transport

The successful deployment of connected and automated vehicles (CAVs) will largely depend on public opinion. Expectations and concerns are essential components driving the speed of market uptake and final adoption of these technologies. We have studied user expectations and concerns, as well as their provenance, by conducting a series of Focus Group (FG) discussions with transport area experts and non-expert participants, in Italy, Germany, and Spain. Together with user acceptance, potential advantages and disadvantages that CAVs may bring at a societal level were explored. Results show that benefits like increased safety and accessibility and improved travel experience for both driver and passengers could support CAVs’ deployment. Nevertheless, a variety of concerns were raised during the discussions, related to privacy, responsibility in case of an accident, and increase in maintenance and repair costs. These aspects could significantly hamper or delay CAVs acceptability and need to be carefully considered by stakeholders. The reported insights from the FG discussions and the fact that some participants noted positive changes of their initial idea of CAVs due to their participation in the discussion, exemplify the importance of citizen engagement activities to address mobility challenges.     

Heuristics and biases in mental arithmetic: revisiting and reversing operational momentum

ABSTRACT

Mental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum (OM) effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems (e.g., 3+0, 3?0) but reverse OM with non-zero problems (e.g., 2+1, 4?1). In a third experiment, we tested the prediction of our model. Our results suggest the presence of at least three competing biases in mental arithmetic: a more-or-less heuristic, a sign-space association and an anchoring bias. We conclude that mental arithmetic exhibits shortcuts for decision-making similar to traditional domains of reasoning and problem-solving.     

Strategic Maneuvering with Dissociation

This paper explores the possibilities for strategic maneuvering of the argumentative technique that Perelman and Olbrechts-Tyteca (The New Rhetoric. A Treatise on Argumentation, University of Notre Dame Press, Notre Dame/London, 1969) called dissociation. After an exploration of the general possibilities that dissociation may have for enhancing critical reasonableness and rhetorical effectiveness, the use of dissociation in the successive stages of a critical discussion is examined. For each stage, first, the dialectical moves that dissociation can be employed in are specified, then, the specific ways in which dissociation contributes to fulfilling the dialectical tasks that are associated with these moves are delineated, and, finally, the rhetorical gain that␣dissociation can bring in the fulfillment of these tasks is discussed. Some general conclusions are drawn for research that aims at understanding the potential of an argumentative technique for strategic maneuvering.     

Qualité des débats sur le travail : la confiance en question

The National Interprofessional Agreement of 2013 on the quality of life at work shows a willingness to institute discussion spaces allowing employees to express themselves on the quality of their work. This questions the modalities of the discussion for those who initiate it as well as for those who participate in it, trust seeming to be indispensable in order to allow for transparency and debate. The authors propose to take a further step from the analysis of a professional controversy by identifying the need to share common assumptions among peers to develop debates.

Selective postevent review and children's memory for nonreviewed materials

Two experiments investigated the impact of selective postevent questioning on children's memory for nonreviewed materials. In both experiments, children participated in a series of novel activities. Children in the selective-review condition were subsequently questioned about half of these and comparisons were made to memory in a no-review condition. In Experiment 1, participants were 60 5- and 9-year-olds. For children in both age groups, memory for nonreviewed activities was impaired 20 min later in free recall. In Experiment 2, participants were 60 5-year-olds. Memory impairment was found following a 1-day delay after spaced review (three sessions over 3 days) but not after massed review (three sessions on 1 day). In both experiments, memory impairment was absent when specific retrieval cues were provided. The possible mechanisms underlying these findings and their potential practical implications are discussed.     

Pre-event discussion and recall of a novel event: how are children best prepared?

We investigated the conditions under which information 1 day before a novel event influenced 6-year-olds' recall 2 weeks later. In Experiment 1A, four preparation conditions included either the event goals, goals with narration of the event actions and objects, photographs of the objects with goals and narration, or photographs with narration and child verbalization of the actions and objects. Compared with an irrelevant preparation control condition, goals with narration reduced errors, but correct recall was increased only when photographs were included. Child verbalization together with goals, narration, and photographs increased correct recall relative to goals with narration. In Experiment 1B, neither photographs nor preparation alone improved recall relative to the control condition. Experiment 2 found no further advantage of increasing children's participation in the preparation via questions. Overall, the impact of preevent information on memory is influenced by the nature of the information and the child's participation in the preparation.     

Gender Differences in Cognitive Vulnerability to Depression and Behavior Problems in Adolescents

This study assessed gender differences in cognitive variables as an explanation for gender differences in depression and behavior problems; 856 adolescents (491 females and 365 males), aged 14–17, completed the Irrational Beliefs Scale for Adolescents, the Social Problem Solving Inventory—Revised Short Form, the adolescent version of the Burnett Self-Talk Inventory, and the Youth Self Report. Female adolescents lower levels of positive thinking and higher scores on negative problem orientation, need for approval and success, and self-focused negative cognitions partially mediated gender differences in depressive symptoms. Males higher scores on justification of violence beliefs and the impulsivity/carelessness style of problem solving partially accounted for differences in delinquent behavior. The influence of need for approval and success on depressive symptoms was higher among adolescents at ages 14–15 than among older adolescents. Justification of violence did not influence delinquent behavior among girls at age 14–15.     

Coping and Psychological Distress as a Function of the Bully Victim Dichotomy in Older Children

While it has been well established that bullying and being bullied have negative psychological consequences for children, the more recent literature has suggested a more complex relationship based on social cognition. A debate has arisen as to whether bullies have deficits or strengths in social cognition. In a study of 236 children (112 males and 124 females) aged between 12 and 15 years the current research explored three main aspects of social cognition, problem-solving style, perceived control and optimism in both bullies and victims. The findings suggest that the debate may hinge on whether the bullies are also victims. In this study bullies had higher scores on problem-solving control while bully victims had the lowest scores. These variations corresponded to differences in psychological distress suggesting that bullies may have developed more effective coping strategies with the reverse being true for bully victims     

Talking about parts of a past experience: The impact of discussion style and event structure on memory for discussed and nondiscussed information

This experiment examined the impact of selective postevent discussion of high- and low-elaborative styles on 5- and 6-year-olds' (N = 47) memory for discussed and nondiscussed aspects of a staged event ("Visiting the Pirate"). The event contained both logically and arbitrarily connected scenes. Discussion was spaced over 3 days, and memory was assessed 1 day later. Compared with a no-discussion condition, memory for discussed information was enhanced after high- but not low-elaborative discussion for both logically and arbitrarily connected scenes. For arbitrarily connected scenes, memory for nondiscussed aspects was impaired relative to the no-discussion condition, with the degree of impairment being equal after high- and low-elaborative discussion. In contrast, for logically connected scenes, memory for nondiscussed information was not impaired after discussion of either style.
