Workplace incivility has significant adverse consequences for targets. However, we know remarkably little about how targets of incivility cope and even less about which coping strategies are effective. Drawing on the coping process of the transactional model of stress, we examine confrontation as a form of problem-focused coping and avoidance as a form of emotion-focused coping in response to incivility. We examine the effects of these coping strategies on reoccurrence of incivility, incivility enacted by targets, psychological forgiveness, and emotional exhaustion. Focusing on the target's perspective of a series of uncivil interactions between a target and perpetrator, we conducted a 3-wave study of employees from various occupations. Employing the critical incident technique, participants reported on an incident of workplace incivility, and then answered a series of questions over 3 waves of data collection regarding their interactions with this perpetrator. Our findings suggest that confrontation and avoidance are ineffective in preventing reoccurrence of incivility. Avoidance can additionally lead to increased emotional exhaustion, target-enacted incivility, and lower psychological forgiveness. However, confrontation coping has promise with regards to eliciting positive outcomes such as psychological forgiveness that are beneficial to interpersonal workplace relationships.

The effects of confrontation and avoidance coping in response to workplace incivility.

Texting while walking has been highlighted as a dangerous behavior that leads to impaired judgment and accidents. This impairment could be due to task switching which involves activation of the present task and the inhibition of the previous task. However, the relative contributions of these processes and their brain activity have not yet been studied. We addressed this gap by asking participants to discriminate the orientation of an oncoming human shape in a virtual environment while they were: i) walking on a treadmill, or ii) texting while walking on a treadmill. Participants' performance (i.e., correctly identifying if a walker would pass them to their left or right) and electroencephalography (EEG) data was collected. Unsurprisingly, we found that participants performed better while they were only walking than when texting while walking. However, we also found that the diminished performance is differently related to task set inhibition and task set activation in the two conditions. The alpha oscillations, which can be used as an index of task inhibition, have a significantly different relation to performance in the two conditions, the relation being negative when subjects are texting. This may indicate that the more inhibition is needed, the more the performance is affected by texting. To our knowledge, this is the first study to investigate the brain signature of task switching in texting while walking. This finding is the first step in identifying the source of impaired judgment in texting pedestrians and in finding viable solutions to reduce the risks.

Texting while walking: An expensive switch cost.

Online health care consultation has become increasingly popular and is considered a potential solution to health care resource shortages and inefficient resource distribution. However, many online medical consultation platforms are struggling to attract and retain patients who are willing to pay, and health care providers on the platform have the additional challenge of standing out in a crowd of physicians who can provide comparable services.

Distracted walking is an ever-increasing problem. Studies have already shown that using a smartphone while walking impairs attention and increases the risk of accidents. This study seeks to determine if smartphone-addiction proneness magnifies the risks of using a smartphone while walking. In an experimental design, participants, while walking on a treadmill and engaged in a smartphone task, were required to switch tasks by responding to an external stimulus, i.e., determining the direction of movement of a point-light walker. Participants were chosen to cover a range of smartphone-addiction proneness. Four smartphone-use conditions were simulated: a control condition with no smartphone-use, an individual conversation condition, a gaming condition, and a group conversation condition. Our results show that using a smartphone while walking decreases accuracy and increases the number of missed stimuli. Moreover, participants with higher smartphone-addiction proneness scores were also prone to missing more stimuli, and this effect was found regardless of experimental condition. The effect of the smartphone task on accuracy and the number of missed stimuli was mediated by the emotional arousal caused by the smartphone task. Smartphone-addiction proneness was positively correlated with a declared frequency of smartphone use while walking. Furthermore, of all the smartphone tasks, the gaming condition was found to be the most distracting.
