[HTML][HTML] Phasic alertness is unaffected by the attentional set for orienting

N Dietze, CH Poth - Journal of Cognition, 2022 - ncbi.nlm.nih.gov
Warning stimuli preceding target stimuli for behaviour improve behavioural performance,
which is referred to as phasic alerting. Similar benefits occur due to preceding orienting cues …

Warning signals only support the first action in a sequence

N Dietze, L Recker, CH Poth - Cognitive research: principles and …, 2023 - Springer
Acting upon target stimuli from the environment becomes faster when the targets are
preceded by a warning (alerting) cue. Accordingly, alerting is often used to support action in …

Phasic alerting in visual search tasks

N Dietze, CH Poth - Attention, Perception, & Psychophysics, 2024 - Springer
Many tasks require one to search for and find important objects in the visual environment.
Visual search is strongly supported by cues indicating target objects to mechanisms of …

[HTML][HTML] Vision rivals audition in alerting humans for fast action

N Dietze, CH Poth - Acta Psychologica, 2023 - Elsevier
Successful behaviour requires that humans act promptly upon the ubiquitous rapid changes
in the environment. Prompt actions are supported by phasic alertness, the increased …

[HTML][HTML] Alerting effects require the absence of surprise

N Dietze, G Horstmann, CH Poth - Acta Psychologica, 2024 - Elsevier
Ongoing actions are interrupted for a brief period of time whenever salient and expectancy-
discrepant stimuli (surprise stimuli) interfere with the present task set. By contrast, salient …

G Girardi, LG Fernandez, M Leboyer… - Autism …, 2021 - Wiley Online Library
Research suggested the possibility that temporal cognition may be different in autistic
spectrum disorder (ASD). Although there are some empirical studies examining timing ability …

[HTML][HTML] Readiness for Perception and Action: Towards a More Mechanistic Understanding of Phasic Alertness

CH Poth - Journal of Cognition, 2025 - pmc.ncbi.nlm.nih.gov
Human survival requires prompt perception and action to address relevant events in the
environment. For this, the brain has evolved a system that uses warning stimuli to elicit …

Temporal expectancy modulates stimulus–response integration

P Schmalbrock, C Frings - Attention, Perception, & Psychophysics, 2022 - Springer
We can use information derived from passing time to anticipate an upcoming event. If time
before an event varies, responses towards this event become faster with increasing waiting …

Dynamics of attention and arousal in healthy and migraine populations

R Masson - 2020 - theses.hal.science
Attention is the cognitive ability which allows us to select and preferentially process relevant
information in our environment. It relies on a balance between top-down and bottom-up …
