Topic: sustained attention

Lapses in attention are ubiquitous and, unfortunately, the cause of many tragic accidents. One potential solution may be to develop assistance systems which can use objective, physiological signals to monitor attention levels and predict a lapse in attention before it occurs. As it stands, it is unclear which physiological signals are the most reliable markers of inattention, and even less is known about how reliably they will work in a more naturalistic setting. My project aims to address these questions across two experiments: a lab-based experiment and a more ‘real-world’ experiment. In thi

Three studies conducted in the context of PhD work (UNIL) aimed at proving evidence to address the question of potential gender differences in trait anxiety and executive control biases on behavioral efficacy. In scope were male and female non-clinical samples of adult young age that performed non-emotional tasks assessing basic attentional functioning (Attention Network Test – Interactions, ANT-I), sustained attention (Test of Variables of Attention, TOVA), and visual recognition abilities (Object in Location Recognition Task, OLRT). Results confirmed the intricate nature of the relationship

Perception of external stimuli slowly drifts between phases of increased and decreased sensitivity in sustained attention tasks. This phenomenon may represent a deliberate cognitive strategy to balance evidence accumulation against evidence gathering according to the predictive coding hypothesis, or it might simply indicate computational bottlenecks. Here, we claim that dynamical systems theory and large-scale network modeling may offer crucial insights to adjudicate this debate. We attempt to harmonize brain dynamics with dual processing modes by suggesting a link with another aspect of neuro

Sustained attention is the focusing attention process on the selected stimulus for a long time, which can be measured with sustained attention to response task (SART). Our research group aimed to investigate the age-related changes in inhibitory functions with electroencephalography (EEG) in theta oscillations. The EEG of 19 healthy individuals (young, 18-25 years old, M = 21.71, SD = 2.06; elderly 55-70 years old, M = 62.43 , SD = 6.33) was recorded at the F3, Fz, F4, C3, Cz, C4, P3, Pz, P4, O1, Oz, and O2 locations during the auditory SART. The maximum power of the target stimuli was calcula

Neurofibromatosis type 1 (NF1) is one of the most prevalent rare genetic diseases, confronting patients with numerous medical (neurological, cutaneous, osseous) and neuropsychological symptoms. To identify risk factors and allow for targeted neuropsychological intervention, potential associations between the heterogenous somatic and cognitive phenotype have been proposed.The present study harnesses the benefits of machine learning analysis to investigate potential non-/linear associations between the medical and neuropsychological profiles of n=236 pediatric NF1 patients.
