TLDR
The results suggest that pupil size discriminates during and after different kinds of emotional stimuli, and the measurement of pupil size variation my be a potentially useful computer input signal, for example, for affective computing.Abstract:
This paper investigated in two experiments pupillary responses to emotionally provocative sound stimuli. In experiment one, 30 subjects' pupillary responses were measured while listening to 10 negatively and 10 positively arousing sounds, and 10 emotionally neutral sounds. In addition, the subjects rated their subjective experiences to these stimuli. The results showed that the pupil size was significantly larger after highly arousing positive and negative stimuli than after neutral stimuli with medium arousal.In experiment two, the contents of the stimuli were more controlled than in experiment one. 22 subjects' pupillary responses were measured while listening to four negatively and four positively arousing sounds, and four emotionally neutral sounds. The results showed that the pupil size was significantly larger during negative highly arousing stimuli than during moderately arousing positive stimuli. The pupil size was also significantly larger after highly arousing negative stimuli than after moderately arousing neutral and positive stimuli.The results of the two experiments suggest that pupil size discriminates during and after different kinds of emotional stimuli. Thus, the measurement of pupil size variation my be a potentially useful computer input signal, for example, for affective computing.read more

The pupil as a measure of emotional arousal and autonomic activation
TL;DR: Pupillary changes during picture viewing covaried with skin conductance change, supporting the interpretation that sympathetic nervous system activity modulates these changes in the context of affective picture viewing.

Infants deploy selective attention to the mouth of a talking face when learning speech
TL;DR: The current findings demonstrate that the development of speech production capacity relies on changes in selective audiovisual attention and that this depends critically on early experience.

Visual complexity of websites: Effects on users' experience, physiology, performance, and memory
TL;DR: It is demonstrated that visual complexity of websites has multiple effects on human cognition and emotion, including experienced pleasure and arousal, facial expression, autonomic nervous system activation, task performance, and memory, and it should thus be considered an important factor in website design.

The effects of affective interventions in human -computer interaction
Timo Partala,Veikko Surakka +1 more
TL;DR: The results suggest that both types of affective intervention had beneficial effects over ignoring the user and further that positive intervention may be especially useful.

Pupillary contagion: central mechanisms engaged in sadness processing
TL;DR: It is shown that diminishing pupil size enhances ratings of emotional intensity and valence for sad, but not happy, angry or neutral facial expressions, and this effect was associated with modulation of neural activity within cortical and subcortical regions implicated in social cognition.

TL;DR: Reports of affective experience obtained using SAM are compared to the Semantic Differential scale devised by Mehrabian and Russell (An approach to environmental psychology, 1974), which requires 18 different ratings.

Affective Computing
TL;DR: Key issues in affective computing, " computing that relates to, arises from, or influences emotions", are presented and new applications are presented for computer-assisted learning, perceptual information retrieval, arts and entertainment, and human health and interaction.

Looking at pictures: affective, facial, visceral, and behavioral reactions
TL;DR: Responsibility specificity, particularly facial expressiveness, supported the view that specific affects have unique patterns of reactivity, and consistency of the dimensional relationships between evaluative judgments and physiological response emphasizes that emotion is fundamentally organized by these motivational parameters.

TL;DR: Using a large emotional picture library, reliable affective psychophysiologies are shown, defined by the judged valence (appetitive/pleasant or aversive/unpleasant) and arousal of picture percepts.
