Predator mimicry, not conspicuousness, explains the efficacy of butterfly eyespots
2015
Large conspicuous eyespots on butterfly wings have been shown to deter predators. This has been traditionally explained by mimicry of vertebrate eyes, but recently the classic eye-mimicry hypothesis has been challenged. It is proposed that the conspicuousness of the eyespot, not mimicry, is what causes aversion due to sensory biases, neophobia or sensory overloads. We conducted an experiment to directly test whether the eye-mimicry or the conspicuousness hypothesis better explain eyespot efficacy. We used great tits ( Parus major ) as model predator, and tested their reaction towards animated images on a computer display. Birds were tested against images of butterflies without eyespots, wi…
Validación de una Medida de Clima de Servicio en las Organizaciones
2012
Service climate is critical for organizations pertaining to the service sector. It reflects the importance organizations attribute to service quality and efforts to please customers. Using previous work of Schneider, White, and Paul (1998) as starting point, this research validates a measure of service climate in the Spanish language. Data from two survey study projects were brought together. A total of 120 hotels, located in Spain, participated in the research. The sample consisted of 508 frontline hotel employees distributed in 152 work-units. Our results confirmed that construct and predictive validity are satisfactory, with four factors describing the facets of service climate: Global S…
Le sens du regard Contribution sémiotique à la technique de l'eye-tracking face aux packagings produits
2009
International audience; This work is presenting a semiotic point of view of a promising but problematic tool of the communication field -eye-tracking- which is used in various fields to track and exploit the eye-path on an object. Drawing form a list of eye-paths on various packagings, the first step of the analysis was the identification without theoretical a priori- of fixed patterns in these paths. Several models can then be inferred on how the order of acquisition of the elements of an image or a pack might have an influence on the construction of their overall meaning.; Ce travail propose un point de vue sémiotique sur un outil du champ de la communication prometteur mais problématique…
The Australian Sheep-Goat Scale: An Evaluation of Factor Structure and Convergent Validity.
2018
The Australian Sheep-Goat Scale (ASGS) is a commonly used measure of belief in the paranormal. The scale contains items that index extrasensory perception (ESP), psychokinesis (PK), and life after death (LAD). Although, research employs the ASGS as both a general (unidimensional) and factorial (multidimensional) measure, few studies have examined the appropriateness of these solutions. Accordingly, the present paper tested the psychometric integrity of the ASGS via two studies. Study 1 assessed ASGS factorial structure using confirmatory factor analysis. To achieve this, merging of ASGS data from previously published studies and ongoing work created a heterogeneous sample of 1,601 responses…
Geometrinen hahmottaminen sosiaalisena, vuorovaikutteisena ja kehollisena toimintana
2022
Matematiikan ja luonnontieteiden oppimista käsittelevässä tutkimuksessa on viime aikoina korostettu kehon, kognition ja vuorovaikutuksen läheistä yhteyttä. Tässä artikkelissa pohdimme, millä tavoin geometrinen hahmottaminen on sosiaalista, vuorovaikutteista ja materiaalien välittämää kehollista toimintaa. Tarkastelemme eräässä kouluajan ulkopuolella järjestetyssä STEAM-työpajassa kerättyä videoaineistoa keskustelunanalyysin menetelmin. Työpajassa alakouluikäiset oppilaat saivat tehtäväkseen koota pareittain jalkapallon geometrisen representaation 4DFrame-rakennussarjan muoviputkista ja -kiinnikkeistä. Tapaustutkimuksemme osoittaa, miten tämän kaltaisen ohjatun rakennustehtävän aikana katse,…
Anticipatory postural adjustments during joint action coordination
2019
International audience; There is a current claim that humans are able to effortlessly detect others’ hidden mental state by simply observing their movements and transforming the visual input into motor knowledge to predict behaviour. Using a classical paradigm quantifying motor predictions, we tested the role of vision feedback during a reach and load-lifting task performed either alone or with the help of a partner. Wrist flexor and extensor muscle activities were recorded on the supporting hand. Early muscle changes preventing limb instabilities when participants performed the task by themselves revealed the contribution of the visual input in postural anticipation. When the partner perfo…
Le paraître et la parure. Corporéité et animalité chez Merleau-Ponty et Deleuze
2013
This chapter presents an overview on the corporeality and animality in Merleau-Ponty and Deleuze. Ontological dimension of perception was particularly highlighted in the Phenomenology of Perception and this work will deepen considerably even in the visible and invisible by the introduction of theme of the flesh as "depth" and "being latency". Merleau-Ponty draws indeed fundamental philosophical conclusions about the structures of the Environment. Merleau-Ponty discusses the descriptive material assets and perceptual behavior of animals in their own environment, not in the laboratory. It is therefore a radical mistake to pretend to judge of animality in terms of theoretical knowledge. The in…
Counterbalancing salt reduction with aromas and consequences on sensory acceptability: A study with real cheese
2014
Introduction and objective: Unbalanced diet with an overconsumption of salt contributes to the development of cardiovascular disease. Several strategies are currently investigated to design low-salt food while maintaining taste and consumer liking. The strategy relying on cross-modal sensory compensation is being tested within the framework of the EU-TeRiFiQ research project. In this context, this study had for aim to examine whether selected aromas could help to maintain salt and fat perception in low-salt real cheese. Methods: Two commercial cheeses, low-salt cheese (LSC) and regular-salt cheese (RSC), were reprocessed by grinding and addition of a sardine aroma associated to salty taste …
Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity
2020
Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond tho…
Trabajo y TIC en los mayores de 45 años. Un análisis de la introducción al ciberespacio desde la esfera laboral
2018
The inequality in access to cyberspace due to age at the beginning of the twenty-first century was followed by an economic crisis that intensified many socio-labor dynamics. Through a contextualization with INE data and a qualitative sample, the following work tries to capture the attitudes about ICT related to their previous labor trajectories on those over 45 years of age; and, on the other hand, its introduction to cyberspace from work as a conditioner in the perception of crisis, the maintenance of employment or their way out to retirement.
