To replicate premier expression using mild valence and arousal
visual stimuli, emotional words with indices of high temporal resolution were used, such as facial EMG (fEMG) and event-related potentials (ERPs).
From biological perspective, emotion can be observed in the mechanisms of the central nervous system CNS and it observed to be associated with changes of the emotional arousal
Support vector machine kernel classifier is used to order the emotions based on positive and negative value of arousal
and valence features .
Valence and arousal
have been categorized and relationship between physiological signals and arousal
and valence has been studied using Decision Tree (DT), Random Forest (RF), k-Nearest Neighbors (kNN) and Support Vector Machine (SVM) learning algorithms.
Another prominent theory of arousal
is commonly known as inverted U theory, and was developed by Yerkes and Dodson in 1908 (Kerr, 2014).
Indices for each arousal
type were calculated by summing the numbers of each particular arousal
and dividing these sums by hours of total sleep time: ARtotI = total arousals
/total sleep time, respiratory arousal
index (RAI) = respiratory arousals
/total sleep time, limb arousal
index (LAI) = limb arousals
/total sleep time, and spontaneous arousal
index (SAI) = spontaneous arousals
/total sleep time.
Five models were proposed for modeling emotions from Arousal
and Valence: a model to determine the strongest emotion that is felt by the person (called the Strongest Emotion model and based on a model used by Mandryk and Atkins to determine emotions while playing an interactive game), a Mamdani's model and a Takagi-Sugeno's model (both called a rule-based FIS because of the structure of their respective rules), which calculates the angle and the intensity of the emotion and two ANFIS using a grid partition and a fuzzy clustering technique.
Women who received ashwagandha reported improved sexual function scores in the areas of arousal
, lubrication, orgasm, and satisfaction.
Now if I see a patient with delirium and normal arousal
, I want to make sure I rule out a potentially life-threatening illness," he said in an interview.
According to alcohol expectancy theory (Stein, Goldman, & Del Boca, 2000), alcohol expectancy refers to memory associations related to anticipated effects after alcohol use, and this expectancy influences the pattern of drinking behavior by activating automatic affective processes, which include a valence dimension (positive and negative) and an arousal
dimension (high and low).
Furthermore, cognitive appraisal seems to influence mood responses to music (Stratton & Zalanowski, 1991) and music and painting appear to be effective for the induction of basic emotions (happiness, sadness, fear, anger and peace) in adults and can be judged according to pleasantness and arousal
(Juslin & Sloboda, 2010; Kreutz, Ott, Teichmann, Osawa, & Vaitl, 2008).
A foggy, disoriented state, also called confusional arousal
, that occurs when the body beats the brain out of bed.
London, March 27 ( ANI ): A new study has revealed that some women fake orgasms during sex in order to increase their own arousal
A 54-year-old male presented to the psychosexual clinic with symptoms suggestive of persistent genital arousal
disorder of 2years duration.
The results of this study suggest that students designing their class schedules might consider enrolling in classes such as art and creative writing during their nonoptimal circadian arousal
times," explains Mareike Wieth, associate professor of psychological science at Albion College, who headed up the study while at MSU.
