Varda's cinema is intimately a cinema of encounter: in each of them the filmmaker puts herself on the line and opens herself to the other; the encounter with the other is the high road to understanding and determining one's own identity. This contribution analyzes some of Varda's cinematic encounters with the aim of understanding the director's gaze.
Integrating Advanced Visual Information with Ball Projection Technology Constrains Dynamic Interceptive Actions
2014
The role of advanced visual information in ball catching was investigated by integrating video images of action and ball projection technology in four different conditions: Integrated video and ball projection (VBP), Video-Only (VO), Ball Projection-Only (BPO) and Misleading Ball projection (MBP). Hand kinematics and gaze behaviour data were collected from participants who attempted to catch balls one handed in all conditions. During VBP, catching performance was more successful, tracking of the ball occurred earlier and lasted longer, with maximum grip aperture emerging earlier with a slower maximum velocity than in BPO. During VO, movement emerged later than VBP, with larger maximum and m…
Head and Body Coordination during Locomotion and Complex Movements
1994
Publisher Summary This chapter discusses theory in which it is argued that during complex movements, the head is stabilized intermittently under the control of gaze, and that this stabilization allows the head to serve as an inertial guidance platform for the control of multilimb movement. The otolithic organs, sacculus and utriculus, are inertial detectors of linear acceleration of the head in the plane of their macula. It is well established that in normal gravity conditions, although the perceived gravitational vertical deviates from the objective vertical by a few degrees, gravitational reference is used not only for posture but also for perceptual tasks that involve orientation in spac…
Drosophila-inspired visual orientation model on the Eye-Ris platform: Experiments on a roving robot
2011
Behavioral experiments on fruit flies had shown that they are attracted by near objects and they prefer front-to-back motion. In this paper a visual orientation model is implemented on the Eye-Ris vision system and tested using a roving platform. Robotic experiments are used to collect statistical data regarding the system behaviour: followed trajectories, dwelling time, distribution of gaze direction and others strictly resembling the biological experimental setup on the flies. The statistical analysis has been performed in different scenarios where the robot faces with different object distribution in the arena. The acquired data has been used to validate the proposed model making a compa…
Attentional processing biases to threat in schizophrenia: Evidence from a free-viewing task with emotional scenes
2021
Attentional biases to threatening stimuli have been suggested to play a key role in the onset and course of schizophrenia. However, current research has not completely demonstrated this assumption. The aim of this eye-tracking study was to shed light on the underlying psychological mechanisms of schizophrenia by examining the attentional processing of socio-emotional information. Forty-four individuals with schizophrenia and 47 healthy controls were assessed in a 3-s free-viewing task with a social scene (i.e., happy, threatening, or neutral) in competition with a non-social one to determine the effects of emotional information on the different stages of the attentional processing. The loca…
Observing animals and humans : dogs target their gaze to the biological information in natural scenes
2020
Background This study examines how dogs observe images of natural scenes containing living creatures (wild animals, dogs and humans) recorded with eye gaze tracking. Because dogs have had limited exposure to wild animals in their lives, we also consider the natural novelty of the wild animal images for the dogs. Methods The eye gaze of dogs was recorded while they viewed natural images containing dogs, humans, and wild animals. Three categories of images were used: naturalistic landscape images containing single humans or animals, full body images containing a single human or an animal, and full body images containing a pair of humans or animals. The gazing behavior of two dog populations,…
“You look at it, but will you choose it”: Is there a link between the foods consumers look at and what they ultimately choose in a virtual supermarke…
2022
Most of the studies that showed a link between gaze allocation and consumer's food choices were performed on food products belonging to a same category. However, consumers usually make food choices in more complex environments, between many different products, and different factors can influence their choices. Therefore, our study aimed to understand the link between gaze behavior and food choices in a complex and realistic situation of choice. Participants (n=99) performed a food choice task in a virtual supermarket. They had to choose three food products to create a dish in four scenarios evoking different motivations (focus on health, environment, food pleasure, and daily scenario as con…
The Power of Smiling. How Politicians’ Displays of Happiness Affect Viewers’ Gaze Behavior and Political Judgments
2019
It is a common assumption that facial expressions of politicians, such as a smile, are powerful tools to draw attention and evoke positive impressions. However, previous research has not fully linked politicians’ nonverbal behavior, viewers’ visual attention and their political impression formation. To address this gap, the research presented in this chapter uses a multi-method design to explore the role of a politician’s smiling for viewers’ judgments about him. More precisely, a laboratory study examined the visual attention (eye-tracking; n = 122) and spontaneous judgments of viewers (continuous response measurement; n = 125) while the participants were exposed to an excerpt of a German …
Family and Affective Models in Children's Literature. An Approach from the Texts for Early Readers at Valencian Schools
2015
Abstract In previous researches we have offered a panoramic view about the presence of family structures different from the traditional one in children's literature, (Oltra Albiach, 2011), about the (shy) presence of protagonists with homo-parent, single- parent families reconstructed or intercultural in children's titles and about the publications of these characteristics in the literature for first readers that have seen the light in recent years (Oltra Albiach & Pardo Coy, 2013). It is noted that the introduction of these literatures in initial schools remains in general a pending matter, especially if we take into account that it is an ideal level to prevent and treat stereotypes and pr…
Tiempo y escuela. Aportación desde la cronobiología y cronopsicología a la Sociología de la Educación. Anotaciones para la reflexión
2021
La preocupación por una correcta organización de los horarios escolares se centra en el qué (curriculum), el cómo (metodología) y en el cuándo hay que enseñar, pero este cuando se centra en la mayoría de las veces en cómo distribuir las materias a lo largo de la jornada, o en el tipo de jornada escolar. La cronobiología y cronopsicología centran su mirada en la organización de la propia actividad del ser vivo, la persona, y aportan conocimientos sobre los momentos óptimos de determinadas actividades y la conveniencia de respetarlas dentro de unos márgenes adaptativos, como son la activación y el reposo /sueño, el ritmo atencional, la memoria, y la actividad intelectual en su conjunto, mostr…
