Psychologie du frisson esthétique

This study concerns the problem of aesthetic emotions and that of aesthetic chills in particular. We asked thirty subjects to describe a narrative structure (film, play, book) eliciting chills and the phenomenology of the aesthetic experience. A number of non-random redundancies are observable. The stimuli eliciting positive aesthetic chills in our population have a sensorial dimension and their particular properties are often the selfless actions, existential considerations of a very general nature (e.g., the meaning of life), moments of inner recollection or quiet reflection, situations of solidarity and communion (family, couple, friends) or, on the contrary, situations of violent separation (family, couple, friends). In general, when real events are at stake (and not fictional scenes as in a film or a novel), subjects describe situations where they are safe, where they trust the environment.     

Intrinsic Versus Extrinsic Motivation in Schools: A Reconciliation

This article explores the nature of the relationship between intrinsic and extrinsic motivation in schools, and in particular examines critically the assertion that these processes are necessarily antagonistic. The weight of evidence suggests that rewards in the form of school grades and the focus of many students on doing well, gradewise, need not necessarily interfere with learning for its own sake. Educational implications of these findings are considered. One such implication is that focusing on students' interests can be a valuable motivational strategy.     

Are consonant intervals music to their ears? Spontaneous acoustic preferences in a nonhuman primate

Humans find some sounds more pleasing than others; such preferences may underlie our enjoyment of music. To gain insight into the evolutionary origins of these preferences, we explored whether they are present in other animals. We designed a novel method to measure the spontaneous sound preferences of cotton-top tamarins, a species that has been extensively tested for other perceptual abilities. Animals were placed in a V-shaped maze, and their position within the maze controlled their auditory environment. One sound was played when they were in one branch of the maze, and a different sound for the opposite branch; no food was delivered during testing. We used the proportion of time spent in each branch as a measure of preference. The first two experiments were designed as tests of our method. In Experiment 1, we used loud and soft white noise as stimuli; all animals spent most of their time on the side with soft noise. In Experiment 2, tamarins spent more time on the side playing species-specific feeding chirps than on the side playing species-specific distress calls. Together, these two experiments suggest that the method is effective, providing a spontaneous measure of preference. In Experiment 3, however, subjects showed no preference for consonant over dissonant intervals. Finally, tamarins showed no preference in Experiment 4 for a screeching sound (comparable to fingernails on a blackboard) over amplitude-matched white noise. In contrast, humans showed clear preferences for the consonant intervals of Experiment 3 and the white noise of Experiment 4 using the same stimuli and a similar method. We conclude that tamarins' preferences differ qualitatively from those of humans. The preferences that support our capacity for music may, therefore, be unique among the primates, and could be music-specific adaptations.
