In order to improve human-computer interaction (HCI), computers need to recognize and respond properly to their user’s emotional state. This paper introduces emotional pattern recognition method of Least Squares Support Vector Machine (LS_SVM). The experiment introduces wavelet transform to analyze the Surface Electromyography (EMG) signal, and extracts maximum and minimum of the wavelet coeffi...

Non-photorealistic rendering (NPR) algorithms are used to produce stylized images, and have generally been evaluated on the aesthetic qualities of the resulting images. NPR-produced images have been used for aesthetic and practical reasons in media intended to produce an emotional reaction in a consumer (e.g., computer games, films, advertisements, and web sites); however, it is not understood ...

The present longitudinal and naturalistic study aimed to investigate fathers’ and infants’ facial expressions of emotions during paternal infant-directed speech. The microanalysis of infant and paternal facial expressions of emotion in the course of the naturalistic interactions of 11 infant – father dyads, from the 2nd to the 6th month, provided evidence that: (a) fathers and infants match the...

The observation Freud made that there is a force, “More primitive, more elementary, more instinctual than the pleasure principle which it overrides . . . independently of it and to some extent in disregard to it,” is pursued by an examination...

Emotional reactions, such as regret and disappointment, are associated with the comparison of an obtained outcome with what might have been. Past research revealed that these counterfactual comparisons affect one’s pleasure with the outcome, at least in the short term. However, whether such effects are transient or long lasting is unknown. The present research explores the time course of outcom...

CONTEXT Heterosexual anal intercourse is a highly efficient mode of HIV transmission, yet little is known about the contexts in which women engage in it, or when and with whom they use condoms. Similarly, sexuality and reproductive health research has paid little attention to female desire and pleasure-seeking. METHODS In-depth interviews were conducted in Boston in 2006 with 28 women who rep...
