Abstract This study contrasted the performance of drivers under actual and simulated driving conditions, in order to assess the validity of the simulators and test the hypothesis that driving is composed of largely orthogonal sub-tasks. Thirty experienced drivers completed an on-road driving test and drove two different simulators, each simulator drive comprising seven difficulty-moderated driving scenarios. Between-simulator contrasts revealed largely absolute validity, the anticipated effects ...

Sleep and circadian rhythms are both considered to be important determinants of mental and physical health. Epidemiological studies characterise sleep by self-reported duration and quality whereas circadian aspects are often captured by self-reported chronotype. Several studies established the independent contribution of sleep duration, sleep quality or chronotype to health. A comparison of the relative contributions of sleep and circadian characteristics to health outcomes is currently not avai...

Abstract Background & Aims Impaired attention and response inhibition has been reported in patients with Crohn’s disease (CD) in clinical remission. Prospective studies are needed to determine whether this is a stable feature of CD and whether a similar impairment is evident in ulcerative colitis (UC). Thus, our aims were to examine whether patients with CD and UC exhibited a persistent impairment in attentional performance, and if this impairment was related to key biological indices of relevan...

Objectives: The prevalence of depression and loneliness are increasing in Western nations, and both have been shown to cause poor sleep quality, with evidence suggesting that loneliness also predicts depression. The Social Cure perspective can shed light on these relationships, and thus informs the present study. Specifically, it was hypothesised that the extent of participants’ identification with a significant social group, their family, would positively predict sleep quality, and that this re...

This chapter is concerned with a research project in which collaboration between psychology, medicine and engineering was necessary to assess the physiological and the psychological perceptions of risk in cyclists, comparing both to determine their impact on wearable technology that measures bodily signals of stress. Here we describe the research design and process, highlighting how insights from all these disciplines were necessary to carry out the project and interpret the conclusions.

Sleep and its sub-states are assumed to be important for brain function across the lifespan but which aspects of sleep associate with various aspects of cognition, mood and self-reported sleep quality has not yet been established in detail. Sleep was quantified by polysomnography, quantitative Electroencephalogram (EEG) analysis and self-report in 206 healthy men and women, aged 20–84 years, without sleep complaints. Waking brain function was quantified by five assessments scheduled across the d...

Background Borderline personality disorder (BPD) is challenging for family members who are often required to fulfil multiple roles such as those of advocate, caregiver, coach and guardian. To date, two uncontrolled studies by the treatment developers suggest that Family Connections (FC) is an effective programme to support, educate and teach skills to family members of individuals with BPD. However, such studies have been limited by lack of comparison to other treatment approaches. This study ai...

AbstractProspective memories can divert attentional resources from ongoing activities. However, it is unclear whether these effects and the theoretical accounts that seek to explain them will generalise to a complex real-world task such as driving. Twenty-four participants drove two simulated routes while maintaining a fixed headway with a lead vehicle. Drivers were given either event-based (e.g. arriving at a filling station) or time-based errands (e.g. on-board clock shows 3:30). In contrast t...

AbstractThis paper shows how to combine field observations, experimental data and mathematical modelling to produce quantitative explanations and predictions of complex events in human–machine interaction. As an example, we consider a major railway accident. In 1999, a commuter train passed a red signal near Ladbroke Grove, UK, into the path of an express. We use the Public Inquiry Report, ‘black box’ data, and accident and engineering reports to construct a case history of the accident. We show...

The sleep–wake cycle and circadian rhythmicity both contribute to brain function, but whether this contribution differs between men and women and how it varies across cognitive domains and subjective dimensions has not been established. We examined the circadian and sleep–wake-dependent regulation of cognition in 16 men and 18 women in a forced desynchrony protocol and quantified the separate contributions of circadian phase, prior sleep, and elapsed time awake on cognition and sleep. The larges...
