Improvement of phonemic fluency following leftward prism adaptation.
2021
AbstractAnatomo functional studies of prism adaptation (PA) have been shown to modulate a brain frontal-parieto-temporal network, increasing activation of this network in the hemisphere ipsilateral to the side of prism deviation. This effect raises the hypothesis that left prism adaptation, modulating frontal areas of the left hemisphere, could modify subjects’ performance on linguistic tasks that map on those areas. To test this hypothesis, 51 healthy subjects participated in experiments in which leftward or rightward prism adaptation were applied before the execution of a phonemic fluency task, i.e., a task with strict left hemispheric lateralization onto frontal areas. Results showed tha…
Can people with chronic neck pain recognize their own digital pain drawing?
2020
Background: Although the reliability of pain drawings (PDs) has been confirmed in people with chronic pain, there is a lack of evidence about the validity of the PD, that is, does the PD accurately represent the pain experience of the patient? Objectives: We investigate whether people with chronic neck pain (CNP) can recognize their own PD to support the validity of the PD in reporting the experience of pain. Moreover, we examined the association between their ability to recognize their own PD with their levels of pain intensity and disability and extent of psychosocial and somatic features. Study Design: Experimental. Setting: University Laboratory. Methods: Individuals with CNP completed …
Perceptual and response bias in visuospatial neglect due to frontal and parietal repetitive transcranial magnetic stimulation in normal subjects.
2002
Recently some authors have challenged the conventional association of directional motor neglect with damage of frontal structures, showing that pure sensory perceptual neglect (classically associated with parietal lesion) can follow damage of right frontal cortex. The aim of the present study was to assess the type of defect in visuo-spatial attention consequent upon a virtual frontal or parietal lesion induced by transcranial magnetic stimulation in normal subjects. To this purpose eleven subjects performed a visuo-spatial task requiring judgement about the length of the two segments of asymmetrically bisected horizontal lines, presented for 50 ms on a computer monitor. After each visual s…
Eye position tunes the contribution of allocentric and egocentric information to target localization in human goal-directed arm movements.
1997
Subjects were required to point to the distant vertex of the closed and the open configurations of the Muller-Lyer illusion using either their right hand (experiment 1) or their left hand (experiment 2). In both experiments the Muller-Lyer figures were horizontally presented either in the left or in the right hemispace and movements were executed using either foveal or peripheral vision of the target. According to the illusion effect, subjects undershot and overshot the vertex location of the closed and the open configuration, respectively. The illusion effect decreased when the target was fixated and when the stimulus was positioned in the right hemispace. These results confirm the hypothe…
Perceiving Need for Lifestyle Counseling
2012
OBJECTIVE To investigate the proportion of individuals at high risk of type 2 diabetes who perceive the need for lifestyle counseling, factors associated with this perception, and whether the perceived need is associated with subsequent attendance in lifestyle intervention. RESEARCH DESIGN AND METHODS Baseline and intervention data were obtained from 10,149 participants in a Finnish National Diabetes Prevention Project. RESULTS In total, 36% of men and 52% of women perceived the need for counseling. Most of the risk factors did not increase the perceived need for counseling. Those agreeing to attend supervised lifestyle intervention were more likely to report a perceived need than those wh…
Croce e Fidler. Le due interpretazioni
2016
Il saggio ricostruisce la storia dell'interesse di Croce per la filosofia dell'arte di Fidler, motivandone le variazioni. This essay deals with Croce's interest for the Fiedlerian Philosophy of Art. It sheds some light on the shifts in his appraisal of Fiedler's achievements.
Does Formal Musical Structure Affect Perception of Musical Expressiveness?
1996
The aim of the study was to assess the effect of systematic modifications in global musical structures on perceived expressiveness. Recorded performances of piano pieces of Bach, Mozart and Schonberg were segmented into short chunks of six seconds in average. These chunks were linked either in a forward order (Original version) or in a backward order (Inverted version). In the inverted version, the formal global structure of the pieces was destroyed, but the superficial features and the local structures inside the chunks were unaltered. Forty non-musician subjects were required to rate the musical expressiveness of these pieces on 29 semantic scales. Half listened to the three original ver…
“The sound of affect”: Age differences in perceiving valence and arousal in music and their relation to music characteristics and momentary mood
2018
Throughout life, music plays an important role in individuals’ everyday affective experiences. Previous findings suggest that preferences for, and perceptions of, music with distinct affective qualities might differ for individuals from different age groups. To date, however, evidence from age-comparative studies across adulthood is rare and little is known about the mechanisms that contribute to age differences in music perception. In an age-heterogeneous sample ranging from adolescence to old adulthood ( n = 50; 12–75 years), we investigated differences in affect perceptions of 147 sounds and 465 songs of various musical styles and dates of origin, as well as the respective roles of musi…
Sonic Strokes and Musical Gestures - The Difference between Musical Affect and Musical Emotion
2009
Musicological theories traditionally address the expressive powers of music within a framework of signification, in which musical affect is considered as a meaningful musical gesture. Consequently, affect is regarded as a property of the music instead of as a bodily reaction of the listener. I will outline a different conception of musical affect that takes into account the bodily nature of perception. I will introduce the notion of sonic stroke, i.e. a sound that induces affect in the listener. A sonic stroke thus is responsible for the occurrence of musical affect. By relating the notion of sonic stroke to musical gesture the differences between the two can be articulated, as well as how …
Handicap et inclusion scolaire au Cameroun : ce qu’en disent les enseignants
2019
International audience; Fondée sur le principe de l'égalité des chances et sur les valeurs humaines d'équité et du respect des différences, l'inclusion scolaire s'attache " à la façon de transformer les systèmes éducatifs et d'améliorer la qualité de l'éducation à tous les niveaux et dans tous les environnements, de manière à s'adapter à la diversité des apprenants et à promouvoir la réussite scolaire " (UNESCO, 2008). Elle est prescrite comme une injonction internationale quels que soient les contextes, elle implique un changement de paradigme dans lequel les conditions de réussite dépendent de la capacité de l'école à s'adapter à la diversité du public qu'elle accueille (Dyson et al., 199…
