A focus group study on the potential of autonomous vehicles as a viable transportation option: Perspectives from people with disabilities and public transit agencies

Autonomous vehicle (AV) technology is becoming one of the most promising alternatives to improve mobility for people with disabilities. Nevertheless, how people with disabilities perceive AV as transportation services has not been explored. Also, limited information exists about how public transit agencies comprehend and perceive autonomous vehicle transportation (AVT) services. This study discusses mobility issues for people with disabilities and explores the potential of AVT to serve that population, particularly those with visual impairments or physical disabilities. Researchers conducted six focus groups comprising people with disabilities (N = 23) and public transit service experts (N = 10) in Austin, Texas and Houston, Texas. Each session was audio-recorded and analyzed using conventional content analysis. This study identified people with disabilities’ mobility issues related to: (1) current transit services (including fixed-route and paratransit services) and (2) the quality of neighborhood built environments. Both people with disabilities and transit experts expected that AVT could mitigate current mobility issues, especially in improved built environments. However, participants with disabilities also expressed concerns and anxieties regarding AVT. Transit experts agreed that more targeted strategies would be needed to overcome possible barriers to AVT for people with disabilities. This study provides insights on shaping AVT strategies and policies relevant to improving mobility for people with disabilities.     

Working memory retrieval differences between medial temporal lobe epilepsy patients and controls: A three memory layer approach

Multi-store models of working memory (WM) have given way to more dynamic approaches that conceive WM as an activated subset of long-term memory (LTM). The resulting framework considers that memory representations are governed by a hierarchy of accessibility. The activated part of LTM holds representations in a heightened state of activation, some of which can reach a state of immediate accessibility according to task demands. Recent neuroimaging studies have studied the neural basis of retrieval information with different states of accessibility. It was found that the medial temporal lobe (MTL) was involved in retrieving information within immediate access store and outside this privileged zone. In the current study we further explored the contribution of MTL to WM retrieval by analyzing the consequences of MTL damage to this process considering the state of accessibility of memory representations. The performance of a group of epilepsy patients with left hippocampal sclerosis in a 12-item recognition task was compared with that of a healthy control group. We adopted an embedded model of WM that distinguishes three components: the activated LTM, the region of direct access, and a single-item focus of attention. Groups did not differ when retrieving information from single-item focus, but patients were less accurate retrieving information outside focal attention, either items from LTM or items expected to be in the WM range. Analyses focused on items held in the direct access buffer showed that consequences of MTL damage were modulated by the level of accessibility of memory representations, producing a reduced capacity.     

Influences on anger in German urban cyclists

Previous research shows that anger and aggression among road users lead to maladjusted driving and a higher risk of accidents. Especially cyclists as vulnerable road users have a high risk of being injured if they are involved in accidents. This paper examines reasons for cycling anger in two studies. The first study aimed at identifying anger provoking events. Seventy-three cyclists were invited to discuss anger provoking events in a focus group setting. These events were rated regarding their anger intensity, clustered within focus groups, and aggregated across all groups. The first study revealed 208 unique cycling anger provoking events of varying anger intensity that were summarized in six clusters. The second study aimed at validating these anger provoking events, the ratings, and the clusters. Here, 129 participants were asked to complete a four-time point diary study (over the course of ten days), in which they registered all anger provoking events that they experienced while cycling. The results of this study validated most of the anger provoking events of the first study. Both studies show that most anger provoking events are related to conflicts between cyclists with other road users like car drivers and pedestrians. Moreover, conflicts with car drivers seem to cause stronger anger among cyclists than conflicts with other cyclists or pedestrians. Implications for further research and the planning of road infrastructure are discussed.     

Outcome interdependence shapes the effects of prevention focus on team processes and performance

Although the effects of regulatory focus on individual-level performance have often been studied, relatively little is yet known about team-level effects. Filling this void, we integrate the notion that promotion-focused individuals are concerned with progress and achievement, whereas prevention-focused individuals are concerned with security and vigilance, with the insight that team processes and performance depend on outcome interdependence (individual versus team rewards). The hypothesis that prevention-focused teams react more strongly than promotion-focused teams to differences in outcome interdependence was tested among 50 teams performing an interactive command-and-control simulation. Regulatory focus and outcome interdependence were both manipulated. The results showed that prevention-focused teams working for team rather than individual rewards reported higher work engagement and less error intolerance, coordinated more effectively, and performed better. Promotion-focused teams were not influenced by outcome interdependence. We discuss the implications of our results for theory and effective team management.     

Les interventions préventives en santé mentale du jeune enfant vues par leurs bénéficiaires : l’exemple du projet CAPEDP

ObjectiveHome-visiting programs have become one of the most popular early childhood interventions, though their impact on parents and children remain uncertain. Outcomes measures often rely on experimental quantitative design and little space is offered for the voices of those served by these interventions. This paper presents the results of a qualitative protocol performed by the research team with participants in the CAPEDP project which took place in France from 2005 to 2011.MethodAll 184 women who had accepted at least one home visit in the CAPEDP programme were contacted and invited to participate. Individual and group interviews were conducted with the first 16 who accepted to participate. The semi-structured interview schedule addressed their overall appreciation of the project, their initial concerns, the quality of their relationship with their home visiting psychologist, positive and negative aspects of the intervention and any recommendations they might have for future interventions. Interviews were recorded, transcribed and anonymised. An inductive categorical thematic analysis was performed by the research team.ResultsParticipants expressed overall satisfaction with the CAPEDP intervention, underlining the quality of the relationships with the home visitors, usefulness of parental guidance, the fact that the intervention could be adapted to suit their own personal agenda, routine and needs, the importance of learning how to accept help and give help to others. Less positive aspects included the fact that the home visitors were not mothers themselves and that they lacked technical experience, the difficulty ending the relationship at the end of the 27-month project, insufficient integration of fathers, the difficult and time-consuming evaluation protocol and the lack of interaction with other parents during the intervention.ConclusionAlthough mothers who accepted to participate in the qualitative interview schedule may have had a more positive overall experience of the CAPEDP project than those who declined to participate, participants’ points of view provide potentially useful indications for adapting future home-visiting programs to the French context.     

The role of attention during retrieval in working-memory span: A dual-task study

We tested the hypothesis that retrieving target words in operation span (OSpan) involves attention-demanding processes. Participants completed the standard OSpan task and a modified version in which all equations preceded all target words. Recall took place under either full attention or easy versus hard divided-attention conditions. Recall suffered under divided attention with the recall decrement being greater for the hard secondary task. Moreover, secondary-task performance was disrupted more by the standard OSpan task than by the modified version with the hard secondary task showing the larger decrement. Finally, the time taken to start recalling the first word was considerably longer for the standard version than for the modified version. These results are consistent with the proposal that successful OSpan task performance in part involves the attention-demanding retrieval of targets from long-term memory.     

Unique associations between anxiety,depression and motives for approach and avoidance goal pursuit

This study investigated the shared and distinct associations between depressive and anxious symptoms and motives for pursuing personal goals. One hundred and thirty-six undergraduates generated approach and avoidance goals and rated each on intrinsic, identified, introjected and external motives. Anxious and depressive symptoms showed significant unique associations with distinct motives. Specifically, depressive symptoms predicted significant unique variance in intrinsic motivation for approach goals (but not avoidance goals), whereas anxious symptoms predicted significant unique variance in introjected regulation for approach and avoidance goals. Some of these findings were moderated by gender. The findings broadly support the notion that depression is uniquely characterised by reduced enjoyment of approach goal pursuit whereas anxiety is uniquely characterised by pursuit of goals in order to avoid negative outcomes. We suggest that these findings are compatible with regulatory focus theory and suggest that motives for goal pursuit are important in understanding the relation between goals and specific mood disorder symptoms.     

Four types of fare evasion: A qualitative study from Melbourne,Australia

Fare evasion on public transport can reduce revenue by millions of dollars, undermining the financial viability of transit. However little research examines how public transport users think about fare evasion or attempts to understand why people fare evade. This paper presents the results of a program of qualitative research conducted in Melbourne, Australia to understand the attitudes toward and motivations behind fare evasion. A total of 67 people participated in face-to-face or online focus groups.Results established a spectrum of perceived circumstances where someone might travel without a valid ticket. ‘Fare evasion’ was considered to be at only one end of that spectrum. The degree of intent to evade was a critical factor explaining the severity of fare evasion from user perspectives. People’s attitudes toward fare evasion differed significantly; four key attitude segments were uncovered based on the attitudes and behaviours that group members tended to share. These included 1. ‘Fare evasion is wrong – the accidental evader’ who held strong views against fare evasion, 2. The ‘it’s not my fault’ evader who meant to pay but sometimes find themselves fare evading due to barriers to payment, 3. The ‘calculated risk-taker’ evader who deliberately fare evade if they think the reward outweighs risk and 4. ‘Career evaders’ who always fare evade. Attitudes, feelings and motivations for these segments are described and implications for revenue protection policy are discussed.     

Repetition of a cognitive task promotes motor learning

Motor learning plays an important role in the acquisition of new motor skills. In this study, we investigated whether repetition of a cognitive task promoted motor learning. Fifty-one young adults were assigned to either the early, late, or control groups. All participants completed a mouse tracking task in which they manipulated a mouse to track a moving target on a screen. The cursor was rotated 165° in the counterclockwise direction from the actual mouse position, requiring participants to learn how to use a new tool. To determine the task performance, we calculated the distance between the cursor and target position. In addition, to assess the effects of a cognitive task on the progress of motor learning, curve fitting of the learning curves was performed for the total distance. Experiments were conducted as per the following schedule: learning day 1 (L1), learning day 2 (L2: the day after learning day 1), retention day 1 (R1: 2 weeks after learning day 1), and retention day 2 (R2: 4 weeks after learning day 1). Participants underwent mouse tracking for 20 min on L1 and L2 and for 3 min on R1 and R2. As a cognitive task, we adopted the N-back task. The early or late group performed the N-back task for 20 min before performing motor tracking task on L1 or L2, respectively. The control group did not perform the N-back task. Based on curve fitting analysis, it was observed that the rate of change for motor learning in the early group was higher than that in the control group. The retention of motor learning did not differ between all groups. Our results indicate that the repetition of a cognitive task enhanced in the early phase of motor learning of the mouse tracking task.
