1481 ALERTNESS AND PERFORMANCE DURING NIGHT WORK CAN BE SERIOUSLY IMPAIRED.1,2 THIS OCCURS BECAUSE THE MASTER CIRCADIAN CLOCK OF MOST night workers, which controls the body�s circadian rhythms (e.g., alertness, temperature, melatonin), does not shift to realign with a night work, day sleep schedule.3 A sharp increase in sleepiness and decrease in performance occurs around the minimum of the cir...

BACKGROUND The synthesis of the neurotransmitters serotonin (5-HT) and dopamine (DA) in the brain can be directly altered by dietary manipulation of their relevant precursor amino acids (AA). There is evidence that altered serotonergic and dopaminergic neurotransmission are both associated with impaired attentional control. Specifically, phasic alertness is one specific aspect of attention that...

The theoretical simplicity of contrasting the notion of energetic search of Baron and Fiet with that of alertness (without search) of Kirzner have been winning over more complex yet more actionable formulations. In contrast, this paper introduces a less dogmatic and more actionable integrated framework that could be viewed as either passive search or active alertness. By investigates how the th...

This study investigated the hypothesis that the influence of time of day on the efficiency of working memory is greater for older than younger adults. Groups of younger and older adults performed a working memory task on 4 consecutive days, twice in the morning and twice in the evening. Objective (body temperature) and subjective (alertness ratings) measures of arousal were taken during each se...

Services offered through the mobile channel are increasing rapidly. However, limited understanding exists on the variation in adoption of these services. This study provides insights on this area by examining factors that influence the adoption of mobile banking services. Based on UTAUT, innovation diffusion, and ubiquitous computing framework, we identity accessibility, alertness, personalizat...

1) I am not sure if the trendlevel result for the influence of sad mood on one of the three visuospatial tests is justification enough for the conclusion: “...alertness and – to a lesser extend – sad mood led to left omissions in visuospatial neglect tests”. The manuscript has been changed accordingly (p.2, ll.10-12). Background: 2) In the literature, the term “unilateral neglect” seems to be c...

This paper presents an experimental study with 47 participants on the influence of lighting on performance and well-being in an office environment. Well-being, alertness and performance were evaluated and measured in two rooms with artificial lighting and one room with day lighting. The evaluations were correlated to cortisol/melatonin saliva samples, illuminance and spectral composition of the...

1673 Sleep Deprivation Disrupts Thermoregulation—Romeijn et al INTRODUCTION It has long been known that sleep and thermoregulation are closely related. This association has traditionally been studied mostly for the association of sleep or alertness with core body temperature.1,2 During the past decade, several studies have suggested this association to be at least in part secondary to an associ...

Background: In contrast to strongly established views on the development of tonic, top-down controlled alertness, a small number neurobehavioral and neurophysiological studies deal with developmental trajectory exogenously driven phasic alertness during childhood. Objective: The current study aimed examine age sex effects alerting late childhood, analyse degree association between tonic at beha...
