Sign Up to like & getrecommendations! Published in 2019 at "Autism Research"
DOI: 10.1002/aur.2178
Abstract: Progression of pupil dilation (PD) in response to visual stimuli may indicate distinct internal processes. No study has been performed on PD progression during a social cognition task. Here, we describe PD progression during the… read more here.

Arousal‐modulated memory encoding and retrieval in adults with autism spectrum disorder
Sign Up to like & getrecommendations! Published in 2022 at "Autism Research"
DOI: 10.1002/aur.2784
Abstract: Recently, we have shown that pupil dilation during a recognition memory task can serve as an index of memory retrieval difficulties in autism. At the time of publication, we were unaware of specific data‐analysis methods… read more here.

DOI: 10.1007/s00221-018-5404-2
Abstract: Interpersonal touch is known to influence human communication and emotion. An important system for interpersonal touch is the C-tactile (CT) system, which is activated by a soft stroke on hairy skin with a velocity of… read more here.

DOI: 10.1016/j.biopsycho.2018.12.013
Abstract: Adjusting behavior following errors is essential for successful goal-directed performance. Error-related pupil dilation indicates increased autonomic arousal and has been shown to predict adaptive adjustments of post-error behavior. Because different types of errors may require… read more here.

DOI: 10.1016/j.cortex.2017.09.025
Abstract: Pupillary responses during cognitive tasks are linked to functioning of the locus coeruleus (LC). The LC is an early site of abnormal tau deposition, which may contribute to key aspects of Alzheimer's disease (AD) pathophysiology.… read more here.

DOI: 10.1016/j.janxdis.2019.04.006
Abstract: Atypical attention to potential social threats, such as emotional faces, may be one of the core mechanisms underlying social anxiety disorder (SAD). Pupil dilation is an index of locus coreuleus-noradrenergic activity, and closely linked to… read more here.

DOI: 10.1017/s0954579420000036
Abstract: Abstract Attention-deficit/hyperactivity disorder (ADHD) is associated with disrupted emotional processes including impaired regulation of approach behavior and positive affect, irritability, and anger. Enhanced reactivity to emotional cues may be an underlying process. Pupil dilation is… read more here.

Pupil dilation reflects the time course of emotion recognition in human vocalizations
Sign Up to like & getrecommendations! Published in 2018 at "Scientific Reports"
DOI: 10.1038/s41598-018-23265-x
Abstract: The processing of emotional signals usually causes an increase in pupil size, and this effect has been largely attributed to autonomic arousal prompted by the stimuli. Additionally, changes in pupil size were associated with decision… read more here.

DOI: 10.1038/s41598-018-31551-x
Abstract: Pupil dilation, an indicator of arousal that is generally regarded as unspecific, amongst others reflects decision formation and reveals choice. Employing letter selection in a Go/NoGo task, we show that choice can robustly be predicted… read more here.

DOI: 10.1038/s41598-018-32646-1
Abstract: Even though human fear-conditioning involves affective learning as well as expectancy learning, most studies assess only one of the two distinct processes. Commonly used read-outs of associative fear learning are the fear-potentiated startle reflex (FPS),… read more here.
