In this chapter psycho-physical methods which are useful for both psycho-acoustics and sound-quality engineering will be discussed, namely, the methods of random access, the semantic differential, category scaling and magnitude estimation. Models of basic psycho-acoustic quantities like loudness, sharpness and roughness as well as composite metrics like psycho-acoustic annoyance will be introdu...

No-reference image quality assessment needs no prior knowledge of reference image. A new fuzzy image quality measure (built from interval type-2 fuzzy sets (IFS2)) is compared with experimental psycho-visual data. The proposed measure is based on IFS2 entropy applied on synthetic images. A recently performed psycho-visual experiment provides psycho-visual scores on some synthetic images, and co...

The goal of our group is to produce immersive virtual reality (VR) experiences that engage the user as a central protagonist in compelling interactive dramas. Our dramas are designed for CAVEs or CAVE-like systems – projection-based, 3-D stereo VR displays with one large screen or multiple screens forming a virtual theater. A tracking system and ”wand,” with joystick and programmable buttons, c...

Psycho-pedagogical theories provide a valuable input for learning. Our goal is to identify requirements for learning environments, conceptually evaluate them, and integrate them into a psycho-pedagogically sound framework as a basis for the development of a highly responsive open learning platform. In this paper we first describe how personal learning processes are conceptualized in our Psycho-...

articles contributed to the Edinburgh Medical Journal. After a review of the various opinions that have been held in England of late years concerning hypnotism, the author proceeds to describe the means used to hypnotise persons, dividing these, as is usually done, into those acting by mental suggestion and those acting by physical stimulation. In doing so, he does not clearly point out that mo...

the notion that genes play an important role in many diseases has been widely accepted, but many find it much harder to acknowledge a similar link with particular behaviour or even predisposition to crime. partly for this reason, the study of behavioural genetics remains a controversial topic, with disagreement not just over the science itself, but even more so about the therapeutic, societal a...

Objective: To identify psycho-emotional disorders diagnosed in women after stillbirth. Design: Cross-sectional study a face-to-face questionnaire. Setting: Postpartum area at a tertiary care referral hospital in León, Guanajuato, México. Participants: 210 women at immediate postpartum, divided into 105 women with stillbirth and 105 with healthy live newborn (controls). Data collection: Women an...

We try to perform geometrization of psychology by representing mental states, " ideas, " ideas by points of a metric space—mental space. Evolution of ideas is described by dynamical systems in metric mental space. We apply the mental space approach for modeling of flows of unconscious and conscious information in the human brain. In a series of models, Models 1-4, we consider cognitive systems ...
