Social context,interpersonal network,and identity dynamics: A social psychological case study of terrorist recidivism

The existing literature on jihadist terrorism has extensively documented the importance of networks, yet the interpersonal element of the networks and how this links to the social identity dynamics of a mujahid have been scarcely explored. It also is still unclear how specific social contexts such as prison, neighbourhood, and home may play a role in the link between interpersonal networks and social identity dynamics. Drawing insights from the social identity perspective, this article examines the relationships between social context, interpersonal networks, and identity dynamics of a mujahid based on a single case of terrorist recidivism in Indonesia. Our analyses showed how transitions across social contexts were related to the subject's opportunities and constraints for the participation in different interpersonal networks that influenced the process of identity negotiation as a mujahid versus alternative identities of family member and belonging to a neighbourhood. It is argued that analysis of the dynamics of a mujahid's identity in local social contexts are an important part of assessing risks of their recidivism.     

A new approach to identifying the effect of diabetic peripheral neuropathy on the ability to drive safely

The purpose of this study was to estimate the potential for impaired driving performance in current drivers with diabetic peripheral neuropathy compared to healthy controls. We analysed, using a driving simulator, three important aspects of driving - use of the accelerator pedal, steering wheel and eye-steering coordination - to test for any differences, and then to integrate these findings to identify a unique pattern of changes in people driving with diabetic peripheral neuropathy. Patients with diabetic peripheral neuropathy displayed differences in use of the accelerator pedal compared to healthy control drivers (p < 0.05) which could be a direct consequence of their sensorimotor impairment due to diabetic peripheral neuropathy. Drivers with DPN used the more extreme high and low positions of the pedal to a greater extent than the Control group who exhibited a more graded use of the accelerator pedal over the mid-range. Eye-steering coordination was also different in drivers with diabetic peripheral neuropathy (p < 0.05) and, as it improved during the second drive, becoming closer to healthy drivers’ values, the occasional loss of control experienced during driving reduced. These insights demonstrate that diabetic peripheral neuropathy affects multiple aspects of driving performance suggesting the need for an integrated approach to evaluate the potential for driving safely in this population.     

Influence of pedestrian-to-vehicle technology on drivers’ response and safety benefits considering pre-crash conditions

Pedestrian-to-vehicle (P2V) technology may offer a promising approach to reducing pedestrian crashes. However, its influences on both driver response and safety benefits have been little studied in previous research, particularly in regard to the variation of influences between different pre-crash scenarios. To investigate these influences, this study designed three pre-crash scenarios based on pedestrian crash contributing factors identified from crash reports, and collected 44 drivers’ driving simulator experiments’ data. The results clarified how using P2V technology to warn drivers of an impending collision improves safety by causing a series of changes for both brake operation and braking profile. These series of changes were further demonstrated to vary between scenarios. The study showed that P2V technology may be particularly useful in scenarios in which a pedestrian’s crossing intention is unclear; specifically, in this type of scenario, the P2V warning had changed the braking process from a panic brake of “slow reaction-hard brake” to a comfortable brake of “quick reaction-gentle brake.” In addition, the P2V warning may be less effective in “low-risk” level scenarios where a driver is confident that he/she can handle the situation through a more conservative evasive action and don’t need to react strongly to a warning. Moreover, depending on the pre-crash scenario, the P2V warning may be mostly beneficial for drivers who had a crash/citation in the past five years and working-aged drivers.     

Scores on a new hazard prediction test are associated with both driver experience and crash involvement

Hazard perception skill has been found to be associated with drivers’ crash risk. This skill has typically been measured using computer-based response-time hazard perception tests, in which drivers indicate the earliest point that they detect a potential hazard in video clips of traffic filmed from a driver’s perspective. In recent years, researchers have suggested an alternative type of measure, known as a “hazard prediction test”, in which each test item is a traffic clip that stops (typically cutting to black) just before a hazardous incident unfolds. Drivers taking the test have to predict what happens next in the clip. Measures of this kind have been found to distinguish between high risk (novice) and lower risk (experienced) driver groups, and have been argued to offer several advantages over traditional response-time hazard perception tests. However, a key strength of the response-time hazard perception test is that assessments using this format have been found to predict crash involvement. The same has not yet been demonstrated for hazard prediction tests, raising questions about their validity. In the present research, we created a new hazard prediction test using Australian traffic scenes. In our version of the test, drivers’ scores were based on how many plausible predictions they were able to generate for each traffic clip. We established validity evidence for the test scores in two studies with separate samples, using two different versions of the test (long vs. short) with different response modes (verbal vs. written). As well as distinguishing between novice and experienced driver groups, test scores were also associated with self-reported crash involvement in both studies. We also found a significant correlation between hazard prediction test scores and scores in an established response-time hazard perception test. These findings support the proposal that scores on the hazard prediction test are a valid measure of hazard perception skill.     

Self-perception of driving abilities in older age: A systematic review

Older adults have become the fastest growing age group worldwide and will continue to make up a more significant portion of the driving population. Given the increased potential for age-related perceptual, cognitive, and physical declines, it is important to understand the perception that older drivers have regarding their own driving abilities. This awareness often motivates their driving behavior and patterns.A systematic review was conducted to synthesize the literature regarding the self-perception of driving abilities in older age. The PRISMA method was used and 10 databases (SCOPUS, TRID, PsycINFO, AgeLine, Web of Science, Abstracts in Social Gerontology, Inspec, Compendex, PubMed, and Medline) were searched to identify relevant articles. A total of 25 articles met the search criteria and were included in the qualitative synthesis.Overall, methods used to assess self-perception of driving abilities in older adults vary considerably. Some studies employ only subjective questionnaires, while others administer questionnaires in addition to on-road driving or simulated evaluations. Nonetheless, the studies overwhelmingly report that older drivers tend to rate highly, and often overestimate, their driving abilities. They perceive their driving abilities to be better than themselves at a younger age, their cohorts, and all other drivers. However, more work is needed to develop improved subjective assessments that guide drivers in more accurately estimating their true driving abilities, as well as to compare subjective ratings to objective performance-based measures of driving abilities.This review may assist researchers in better understanding the characteristics that influence driving self-perception and may inform the development of interventional strategies that help older drivers to better calibrate how they perceive their driving.     

Cross-cultural perspective of driving style in young adults: Psychometric evaluation through the analysis of the Multidimensional Driving Style Inventory

Self-evaluating methods are frequently used to identify driving styles. Among others, one of the most commonly used questionnaires is the Multidimensional Driving Style Inventory (MDSI), developed for the Israeli population. Because of the extensive use of the questionnaire, the present paper aims to validate an Italian version and to confirm the 8-factor structure of the original one, i.e, dissociative, anxious, risky, angry, high-velocity, distress-reduction, patient, and careful driving style. The Italian version of the MDSI was filled out by 561 Italian drivers, who had a driving license for at least 1 year. A confirmatory factorial analysis (CFA) was conducted on the 44-item of the translated questionnaire showing not so good values of the goodness of fit tests (SRMR = 0.085; RMSEA = 0.063). The total-item correlation of each scale indicated that 4 items had a low index of total-item correlation. A second CFA was conducted on the remaining 40 items: goodness fit parameters improved (SRMR = 0.0685, RMSEA = 0.0584). Previous validations of the original version of MDSI for different populations (Argentine, Romanian, Chinese, Malaysian, Butch and Belgian) showed several critical issues in confirming the original structure. In the Italian version of MDSI validated in the present paper, the original 8-factor structure was confirmed by removing the 4 items which did not properly contribute to the factors. The results not only confirmed the usefulness of the MDSI in assessing driving style but they also indicated that the concept of driving style is considered in the same way in Italy and Israel, even though traffic rules are different. The latter consideration raises interesting questions for future research concerning cross-cultural comparisons of driving behavior in different countries.     

Characteristics of unsafe events involving a motor vehicle for group riders in Western Australia: A naturalistic study

Little is known about the safety issues affecting non-professional group riders. This study aimed to identify the most common unsafe events involving a motor vehicle that occurred while group riding, describe their characteristics and suggest potential preventative measures. A naturalistic study collected video footage from cameras attached to the bicycles of group riders who rode on-road for training, fitness or recreation in Perth, Western Australia. Fifty-two riders from 40 different riding groups, recorded footage of 126 group riding trips, resulting in 135 h of video. A total of 108 unsafe events (‘near-crashes/ crash relevant events’ and ‘close passing only events’) involving the group riders and a motor vehicle were observed. The most common type of unsafe event involved a motor vehicle attempting to pass/ overtake the group (65.7%). For 39.4% of the passing events, the presence of road infrastructure ahead (e.g. roundabout, traffic island) prevented safe passing and led to an unsafe event. Motorists were at fault for 83.3% of all unsafe events and reckless behaviour by the motorist was observed for 13.3% of these at-fault events. Aggressive communication on the part of the motorist or rider/s was observed for 15% of all unsafe events. This study highlighted that motorists were at fault for the majority of unsafe events involving group riders but only a small proportion involved reckless behaviour. Further research should examine the effectiveness of motorist education as well as infrastructure modifications on popular group riding routes, for reducing unsafe events involving group riders.     

Humor as a protective factor against anxiety and depression

Background/ObjectivesEven though humor its part of everyday life, only in the last 40 years has Psychology begun to discern its impact on mental health. The aim of this paper is to explore the role that humor styles may have as protectors against anxiety and depression and their relationship with optimism.MethodA sample of 804 participants (M = 39.28; SD = 14.71) was used to analyze the uses of humor, optimism and clinical symptoms of anxiety and depression. In addition, the influence of sociodemographic variables such as sex, geographic location, age and educational level on different uses of humor was studied. Through an analysis of structural equations, the variables that had a protective or facilitating role in depression and anxiety were analyzed.ResultsMen and women differ in the use of a more aggressive humor style, and the use of affiliative humor styles decreases with age. The structural equation model indicated a good fit to the proposed theoretical model.ConclusionsHumor is a tool of everyday life and it can act for or against an individual’s mental health.     

Spanish adaptation of the Personal Meaning Profile-Brief: Meaning in life,psychological well-being,and distress

Background/ObjectiveThis study aimed to adapt the Personal Meaning Profile-Brief (PMP-B) to the Spanish-speaking population and investigate its psychometric properties. The PMP-B is a 21-item instrument that assesses meaning in life through seven sources: relationship, intimacy, achievement, self-acceptance, self-transcendence, fair treatment, and religion.MethodParticipants were 546 Spanish adults comprised of a community sample (n = 171) and university students (n = 375). The PMP-B, the Ryff's Scales of Psychological Well-Being, and the Depression Anxiety Stress Scale were administrated.ResultsThe PMP-B showed a bifactor structure with one general factor and seven subfactors. Measurement invariance was found across age, gender, and samples. Internal consistency and test-retest reliability were generally good. Older people showed higher PMP-B scores than younger people. The PMP-B scores, especially relational sources of meaning, were positively associated with psychological well-being and negatively related to psychological distress, mainly to depression.ConclusionsThe validity evidence gathered in this study supports the reliable use of the PMP-B to measure meaning in life. The PMP-B can be a noteworthy contribution to the meaning-centered research.
