Multitasking was assessed using the Edinburgh Virtual Errands Test (EVET). Participants were asked to memorize either good or poor plans for performing multiple errands and were assessed both on task completion and on the extent to which they modified their plans during EVET performance.

This study replicates and extends these findings. Under simulated driving conditions, two groups of drivers experienced conditions that would either increase angry mood (N= 12; men= 6) or not (control group, N= 12; men= 6). All drivers then performed a neutral drive, during which they encountered a number of traffic events not experienced in the initial drive.

This paper reports an investigation into the socio-technical implications of maintaining a difficult conversation while driving. Twenty romantically involved couples participated in a driving-simulator experiment. The participants engaged in emotionally difficult conversations while one partner drove. The contentious conversation topics were identified using a revealed differences protocol, requiring partners to discuss sources of ongoing disagreement in their relationship. The conversations were conducted either using handsfree telephone or with both parties present in the simulator. Results indicate that the revealed differences tasks were subjectively viewed as emotionally more difficult than a control. Driver performance was found to be adversely effected for both longitudinal and lateral vehicle control. Performance was worst during contentious conversations with the partner present, suggesting the drivers may be better able to regulate driving task demands with the partner not in the vehicle during difficult discussions.

However, within the driving context, anger has often, but not always, been considered from either a person-centred approach, examining the influence of trait factors and individual differences in driving anger, or from a situation-focussed perspective, considering anger as a response to the current driving situation. The research reported in this thesis aimed to investigate the role of the individual ...
