TLDR
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz tone, and a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation.Abstract:
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz 80 dB tone For one group a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation These two groups were compared with a group who heard the same stimuli but were simply instructed to relax The three groups differed in level of arousal according to KEG signs of drowsiness, skin conductance level, and frequency of spontaneous skin conductance responses, All three groups differed from each other in number of trials to habituation criterion for skin conductance responses to stimuli Since the delay of habituation was seen tin- both the Task group and the Shock-threat group, it was concluded that the effect was not bound to aspects of stress but was a general effect of increased arousal For vasomotor responses an analysis in terms of habituation was difficult to apply because the two high arousal groups were very unresponsive from the beginningread more

Emotions Matter: Towards Personalizing Human-System Interactions Using a Two-layer Multimodal Approach
TL;DR: In this article , a hierarchical machine learning approach was proposed to predict task performance by considering cognitive workload, physiological responses, and affective states, and the results showed that the proposed approach always outperformed the models that only use physiological information.

TL;DR: Monitoring of pupil size is proposed as a promising biomarker for CDD and machine learning reveals that both behavioral and pupillometry parameters can be considered good predictors of CDD.

Examining the indirect contributions of irritability and chronic interpersonal stress on symptoms of anxiety and depression in adolescents.
TL;DR: In this article , the authors used three cross-lagged panel models to investigate the indirect effects of irritability and chronic interpersonal stress on anxiety and depression symptoms using data from 627 adolescents over a six-year period.

A physiological model of phobic anxiety and desensitization.

TL;DR: An alternative explanation consistent with the above postulate states that the underlying mechanism of systematic desensitization is identical with that of habituation proceeding under optimal conditions (the “maximal habituation” hypothesis).

The orienting reflex during waking and sleeping
Laverne C. Johnson,A. Lubin +1 more
TL;DR: There was little, if any, habituation of the OR during sleep, and the presence of a stimulus-evoked K complex was associated with increased responsiveness in all autonomic variables, but presence of eye movement bursts wasassociated with decreased cardiovascular response to the tone.

Self-reported arousal: further development of a multi-factorial inventory.
Anders Kjellberg,Gunilla Bohlin +1 more
TL;DR: The previously presented inventory of self-reported arousal, which contained four factor analytically derived scales, was further developed in the following way: the original factor pattern was cross-validated and a new response scale was constructed which proved to be superior to the old one.
