“…That each phase was only 5 s in duration was a modification of the methodology used with humans where each exposure was 6 s long [27]. This means that only short exposure times to the stimuli were used.…”

“…We were able to increase the duration of the recording from 5 s to 20 s using a novel stitching method. To our knowledge there are four studies that analysed short HRV intervals [27,47,48,49]. While Valenza et al [49] suggested an advanced computerized method to estimate emotions of less than 10 s, we on the other hand propose a non-computerized stitching method as a potential tool to investigate short-time HRV.…”

A test session consisted of four presentation phases (1 st exposure to stimulus, post exposure, 2 nd exposure, and access to reward). Heart rate (HR) and heart rate variability (HRV) responses were recorded during testing in the experimental room and also when lying resting in a quiet familiar room. A new method of 'stitching' short periods of HRV data together was used in the analysis. When testing different stimuli, no significant differences were observed in HR and LF:HF ratio (relative power in low frequency (LF) and the high-frequency (HF) range), implying that the sympathetic tone was activated similarly for all the stimuli and may suggest that dogs were in a state of positive arousal. A decrease of HF was associated with the meatball stimulus compared to the food pellet and the reward phase (interacting with the person or eating the food) was associated with a decrease in HF and RMSSD (root mean square of successive differences of inter-beat intervals) compared to the preceding phase (looking at the person or food). This suggests that parasympathetic deactivation is associated with a more positive emotional state in the dog.A similar reduction in HF and RMSSD was found in the test situation compared to the resting situation. This is congruent with the expected autonomic effects related to postural shift i.e. sympathetic activation and parasympathetic withdrawal, during standing versus lying, but it cannot explain the parasympathetic deactivation in response to the more positive stimuli since the dogs were always standing in the test situation. We discuss the systematic pattern of responses, which support that increased HR and LF:HF ratio are associated with emotional arousal, but add the new proposal that a combined decrease in A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT3 RMSSD and HF may reflect a more positively valenced emotional state even when an individual is already in a positive psychological state.

Affect-aware video games can respond to a game player's emotions. Such games seem to be more attractive for users. Therefore for that kind of games it is necessary to create a model of the player's emotions to know to which emotions the application should react. The paper describes different models of emotions. The questionnaire and experiment for video game players is presented. Some results of the tests are shown. Then the model of game player that allows to describe his or her emotions is proposed. 1

“…The same authors conducted a follow-up study in which they investigated how heart rate and skin conductance measures, both physiological indicators of autonomic nervous system activity [67,299], would respond to mediated social touch from a stranger or an actual touch from a loved one [74]. The same device as in the previous experiment was used: five force-sensitive resistors controlled the intensity of vibration of 5 vibration motors on the output side, while a temperature sensor coupled to a Peltier element made it possible for the person on the output side to feel the temperature of the other person's palm.…”
