The function of information immediacy and smartphone usage

The current study used the delay discounting method to understand the need to respond to different communication mediums. In this method, participants were asked their preference between responding immediately for a smaller reward or after a delay for a larger reward. Experiment 1 asked participants their preference for responding to a text message, sticky note, and postcard. Participants indicated lower willingness in responding to the text message but did not have differing preferences between the other mediums. Experiment 2 sought to understand if the effect was related specifically to text messages or all instantaneous communication. Participants indicated their preference for responding to a text message, email, and voicemail while driving on a road trip. Participants indicated no differences in preference for responding to the message mediums. These results have implications for interpreting distracted driving research, specifically texting and driving, as the effect may apply to other communication mediums.     

Factors influencing intentions to text while driving among Polish drivers

Previous research has found that using a mobile phone while driving has a detrimental effect on driver safety and performance. The present study used the Theory of Planned Behaviour (TPB) to examine a number of factors thought to be related to intentions to send or read text messages while driving. A total of 298 Polish drivers completed a survey that included measures of the TPB components related to intentions to send or read text messages in four different scenarios. The scenarios differed according to whether or not the drivers were waiting at traffic lights or travelling at 100 km/h and according to whether or not they were under time pressure. The research found that Attitudes and Perceived Behavioural Control were positive predictors of general intentions to use a mobile phone while driving. Similarly, Attitudes consistently predicted intentions to send and read text messages across the four scenarios. The findings of this study could be utilised for developing an educational campaign aimed at promoting more positive attitudes toward road safety and at reducing intentions to use mobile phones while driving.     

The effectiveness of “Soft-blocking” for reducing clicking on-screen while driving

Smartphone usage while driving is recognized as a compromise on road safety. We investigated if silencing and hiding of notifications from drivers (soft blocking) can reduce clicks on the screen while driving and if the effect of the soft blocking would be different for different speed thresholds (STs) (i.e., at driving speed greater than 0 km/h, greater than 1 km/h….and greater than 90 km/h). Drivers installed a smartphone application, which continuously monitored their phones. In the intervention group (N = 22), the application switched to the soft blocking mode during the study's intervention period, while in the control group (N = 29) it remained in a recording-only mode. We ran a Poisson regression model on the click events frequency (CEF) to estimate the soft blocking effect for each of the STs between 0 and 90 km/h. Our analyses indicated that the soft blocking effectiveness was indeed speed-dependent and pointed to a decline in CEF from ST > 55 km/h and to mixed results if ST < 55 km/h. We identify a potential of soft blocking to reduce phone usage while driving and recommend ST-dependent soft blocking. We also recommend using different STs in future investigations on the effectiveness of soft blocking.     

The impact of self-control and texting-related accidents on the relationship between mindfulness and mobile texting while driving behavior

Distracted driving behavior often occurs when drivers mindlessly send or receive text messages with their mobile devices. It is imperative to understand the relationship between mindfulness and texting while driving behavior because distracted driving behavior has led to a reported increase in texting related accidents and mortalities. Based on this report, the purpose of this study is to examine the relationships between mindfulness, self-control, frequency of texting-related accidents, near-miss accidents, and texting while driving behavior. Using a total of 609 adults with an average age of 34.11 (SD = 12.21), results showed that observe, aware, and describe were related to texting while driving. Additionally, we found evidence that self-control partially mediated the relationship between mindfulness and texting while driving. Results also showed that near-miss texting while driving accidents moderated the relationship between mindfulness and texting behavior while driving. The observed inverse relationship between mindfulness and texting while driving can increase researchers’ understanding of self-control’s role in vehicular accidents triggered by texting. Implications and limitations are offered, along with suggestions for future research.     

Driving performance while using a mobile phone: A simulation study of Greek professional drivers

PurposeThe current study aims to assess the driving performance of professional drivers while using a mobile phone.Material and methodsA sample of 50 male professional drivers participated in the study. The sample was drawn conveniently from the professional drivers’ registries and the main taxi ranks. The inclusion criteria were: (a) age above 18 years, (b) possession of a driving license, (c) sufficient reading, writing, and communicating skills, (d) informed consent prior to participation. Laboratory tests were conducted using the VS500M driving simulator manufactured by Virage Simulation Inc. The intervention involved different tasks/assignments: (a) driving without using a mobile phone (Control time), (b) driving while having a conversation on the mobile phone, (Task_1), (c) driving while reading out loud text messages (Task_2) and, (d) driving while texting (Task_3). Differences in the driving performance between the control time and the time with assignments, were examined. The participants were evaluated on the followings outcome measures: (a) variation of the steering position per second, (b) following distance per second, (c) variation of the lateral lane position per second, and (d) sum of squared acceleration per second.ResultsThe analysis indicated that “variation of the steering position per second” was significantly affected by “text-message reading” [t(50) = −5.443; p < 0.0001] and “texting” [t(50) = −5.442; p < 0.0001]. A significant main effect was observed in terms of the “following distance per second” and the “variation of the lateral lane position per second” for all the three mobile phone assignments. Lastly, the “sum of squared acceleration per second” was significantly decreased during conversation on the phone [t(50) = 2.713; p = 0.009] as well as during texting [t(50) = 3.428; p = 0.001] as compared with the control time.ConclusionsThe study is among the few existing experimental studies in a country with one of the highest road fatalities in Europe but with limited evidence on road traffic behaviour. This study could guide the design of large-scale simulation studies aiming to explore the impact of mobile phone on driving behaviour.     

Driving and gaze behavior while texting when the smartphone is placed in a mount: A simulator study

The aim of this study was to investigate how texting when the smartphone in a mount next to the wheel, negatively affects safe driving behavior and gaze behavior. In most countries hand-held phone use while driving is prohibited. However, when texting is not explicitly forbidden and only hand-held use is not allowed, drivers can still legally operate their smartphone with their fingers when it is placed in a mount which is attached to the dashboard or the windscreen. The effects on driving and gaze behavior of ‘dashboard-mount’ texting have hardly been investigated. Twenty-seven participants drove three short identical drives in a simulator while their driving behavior and gaze behavior was measured. This was a drive in which participants did not text (baseline drive), a drive while they texted with a smartphone in one hand (hand-held drive), and a drive in which they texted while the phone was placed in a dashboard-mount (dashboard-mount drive). Participants looked significantly more often at the smartphone during the dashboard-mount than during the hand-held drive. Total dwell time at the smartphone was significantly longer during the dashboard-mount than during the hand-held drive. There were no significant differences between the two texting drives in the number of glances longer than 2 s, the longest glance of each participant, and mean fixation duration at the smartphone. Total dwell time in the mirrors was significantly shorter during the two texting drives than in the baseline drive but did not differ between the two texting drives. The drivers showed poorer lateral control and varied their speed more in the two texting drives than in the baseline drive. They also drove significantly slower in the two texting drives than in the baseline drive. Finally, subjective workload was much higher in the two texting drives than in the baseline drive. The results indicate that dashboard-mount texting deteriorates the safe execution of the driving task to at least the same extend as hand-held texting does.     

Text messaging, personality, and the social context

The purpose of this research was to undertake some analyses of how the language used in text messaging varies as a function of personality traits and the interpersonal context. After completing personality questionnaires, participants provided their most recent text messages and indicated their relationship with the message recipient on several dimensions. Correlations between Linguistic Inquiry and Word Count (LIWC) categories and personality traits and relationship status were examined. There were significant correlations between certain LIWC categories and extraversion (e.g., personal pronouns), neuroticism (e.g., negative emotion words) and agreeableness (e.g., positive emotion words), suggesting that personality traits are displayed in how one texts. One of the defining features of texting - linguistic alterations (e.g., abbreviations) - varied as a function of both personality traits and relationship status. Overall, the results provide a snapshot of what text messages look like, and how they reflect the texter’s personality and the interpersonal context.
