There are a variety of reasons someone might engage in risky behaviors, such as perceived invulnerability to harm or a belief that negative outcomes are more likely for others than for oneself. However, these risk-taking biases are often measured at a decision-making level or from the developmental perspective. Here we assessed whether or not risk-taking influenced perceptual judgments associat...

Prior neuroimaging work on visual perceptual expertise has focused on changes in the visual system, ignoring possible effects of acquiring expert visual skills in nonvisual areas. We investigated expertise for reading musical notation, a skill likely to be associated with multimodal abilities. We compared brain activity in music-reading experts and novices during perception of musical notation,...

Perceptual constancy of visual motion is usually described as the degree of correspondence between physical and perceived characteristics of motion in the external world. To study it, one has to assess the relationship between physical motion, its retinal image, and its perception. We describe a quantitative estimation procedure for a measure K denoting the degree of perceptual constancy of bac...

We theorized that interpersonal relationships can provide structures for experience. In particular, we tested whether primes of same-sex versus mixed-sex relationships could foster cognitive-perceptual processing styles known to be associated with independence versus interdependence respectively. Seventy-two participants visualized either a same-sex or other-sex relationship partner and then pe...

The finding that the Ebbinghaus/Titchener illusion deceives perception but not grasping is usually seen as strong evidence for Goodale and Milner's (1992) notion of two parallel visual systems, one being conscious and deceived by the illusion (vision-for-perception) and the other being unconscious and not deceived (vision-for-action). However, this finding is controversial and led to studies wi...

BACKGROUND AND PURPOSE Using confirmatory factor analysis, this study evaluates the relative impact of motor, cognitive, and perceptual deficits on functional autonomy with 100 elderly (aged 55 to 79 years) victims of stroke. METHODS Two different approaches were used for measuring functional autonomy: the Functional Autonomy Measurement System (Système de Mesure de l'Autonomie Fonctionnelle ...

This paper investigates the measure of voice quality for a digital speech watermarking scheme using a subjectivity method. Data rate, inaudibility, and robustness are considered more than voice quality in speech watermarking. Since any technique in speech telecommunication should have acceptable quality, the perceptual measurement of voice quality is seen as an important topic in audio and spee...

In this paper, we study the controllability of an Expressive TTS system trained on a dataset for continuous control. The is Blizzard 2013 based audiobooks read by female speaker containing great variability in styles and expressiveness. Controllability evaluated with both objective subjective experiment. assessment measure correlation between acoustic features dimensions latent space representi...

Zhang and Luck (Psychological Science, 20, 423-428, 2009) found that perceptual memories are lost over time via sudden death rather than gradual decay. However, they acknowledged that participants may have instead lost memory for the locations of objects. We required observers to recall only a single object. Although the paradigm eliminated the need to maintain object-location bindings, the pos...

Cross-language voice conversion is useful for many applications, and we are trying to apply the technique to a language training system for reducing voice individuality differences. In this paper, we describe experiments that test effectiveness of an extension of single-language voice conversion, to include cross-language utterances. The performance was investigated by objective and perceptual ...
