Multitâche numérique et compréhension : une revue de la littérature

IntroductionIn recent years, many Anglo-Saxon studies in psychology have focused on the effects of digital technologies on learning, when they are used during study time in class or at home. Such uses have been called media multitasking. The purpose of this article is to report on these recent advances.Literature findingsThrough a literature review of 46 peer-reviewed articles published between 2010 and 2020, we first report information's on learners’ uses demonstrating the prevalence of media multitasking and its effect on academic achievement. We then show that these uses can interfere with the retention of learning content, as well as with comprehension, under certain conditions and in a non-systematic way.Discussion–conclusionFinally, we discuss some recommendations that can be drawn from these studies: considering technologies and including their uses during learning or limiting their uses, depending on educational choices.     

Predicting the Personal Appeal of Marketing Images Using Computational Methods

Images play a central role in digital marketing. They attract attention, trigger emotions, and shape consumers’ first impressions of products and brands. We propose that the shift from one‐to‐many mass communication to highly personalized one‐to‐one communication requires an understanding of image appeal at a personal level. Instead of asking “How appealing is this image?” we ask “How appealing is this image to this particular consumer?” Using the well‐established five‐factor model of personality, we apply machine learning algorithms to predict an image's personality appeal—the personality of consumers to which the image appeals most—from a set of 89 automatically extracted image features (Study 1). We subsequently apply the same algorithm on new images to predict consequential outcomes from the fit between consumer and image personality. We show that image‐person fit adds incremental predictive power over the images’ general appeal when predicting (a) consumers’ liking of new images (Study 2) and (b) consumers’ attitudes and purchase intentions (Study 3).     

Fostering learner autonomy and critical reflection through digital video-journals in a university foreign language course

Many studies have documented the benefits of incorporating reflective journals into foreign language education at university level, though the pedagogic tendency has been to utilise these valuable learning resources to enhance students’ written language skills. This study focuses on how the production of a digital reflective journal in video format can assist in the improvement of oral language abilities in tertiary students of Spanish as a foreign language. With spoken language as the driving vehicle for this assessment task, the course coordinator and educator in charge aimed to promote the development of learner autonomy and self-reflection. In addition, to foster students’ agency in this process, the task incorporated the use of modern digital technologies, which are part of the repertoire of communication channels used by today’s university language learners. Findings suggest that completing this self-reflection assessment task afforded creative teaching and learning experiences, and generated opportunities for learners to improve critical thinking skills, written language proficiency and oral communication. It also heightened their motivation to engage with language-related cultural knowledge, and minimised feelings of anxiety towards communicating verbally in a foreign language.     

Who wants to become more conscientious,more extraverted,or less neurotic with the help of a digital intervention?

Desires to increase in extraversion and conscientiousness as well as to decrease in neuroticism are the three most prevalent personality change goals. This study describes characteristics of people who wanted to change one of these personality traits (total N = 1196) with the help of a digital personality change intervention. The extent to which characteristics predicted the selection of one change goal over the other two was explored using machine learning. Individuals desired to change traits with lower (in case of desires to increase) or higher (in case of desires to decrease) self- and observer-reports and with greater self-other discrepancies. This identification of characteristics of people who desired to change certain personality traits informs future interventions.

Between individualisation and tradition: transforming religious authority on German and Polish Christian online discussion forums

The aim of this paper is to connect the debates on individualisation and mediatisation of religion and transformations of religious authority online on theoretical and empirical basis. The classical and contemporary concepts of individualisation of religion, rooted in the secularisation debate, will be connected with Campbell’s [2007. “Who’s Got the Power? Religious Authority and the Internet.” Journal of Computer-Mediated Communication 12 (3): 1043–1062] concept of four layers of religious authority online. The empirical material consists of a joint analysis of German Christian and Polish Catholic Internet forums. In a transnational comparison, the findings show similar tendencies of individualisation and emerging communities of choice, as well as a lasting significance of textual religious authorities, although different levels of authority are negotiated and emphasised to a varying extent. However, in both cases critique of the Church and religion usually emerges offline, and is then expressed online. While the forums do not have a subversive potential, they facilitate adopting a more independent, informed, and reflexive approach to religion.     

The Dynamics of Cyber China: The Characteristics of Chinese ICT Use

This paper provides a preliminary examination of the use of information and communication technologies (ICTs)—limited to mobile phone and internet use—in contemporary China. Based on fieldwork undertaken since 2003 in Guangzhou and Beijing, the paper focuses on the relationship between society and technology in the Chinese cultural context. An analysis of the data on ICT use in China shows how Chinese cultural traits and the speed of the ICT evolution in China have combined to bring about a unique cyber experience. This analysis may be helpful to other scholars who wish to compare the impact of ICTs in various cultures or who are interested in discovering how Mainland China went ‘cyber’.

Handwriting on a tablet screen: Role of visual and proprioceptive feedback in the control of movement by children and adults

Tablets are increasingly being used in schools for a variety of handwriting tasks. Given that the control of handwriting relies on both visual and proprioceptive feedback, especially in younger writers, this raises the question of whether the texture of the tablet surface affects graphomotor execution. A series of recent studies found that when the smoothness of a tablet screen modifies proprioceptive feedback, the impact on graphomotor execution varies according to the level of the writer’s handwriting skills. However, as the writing on the screen remained visible in these studies, participants may have compensated for the decrease in proprioceptive feedback by relying more heavily on visual information. The aim of the present study was therefore to unravel the respective contributions of different types of sensory feedback during handwriting development and, consequently, the compensatory role of visual information when children and adults have to write on a tablet. To this end, we asked second and fifth graders and adult participants to write letters and pseudowords on a plastic board placed on top of a tablet screen. Participants wrote on either the smooth or the granular side of the plastic board (manipulation of surface friction), and with normal vision or behind a shield that hid the hand and handwriting from direct view (manipulation of vision). Kinematic parameters and legibility were recorded to assess handwriting performances. Results revealed a significant interaction between proprioceptive and visual feedback on letter size, pen speed and legibility, regardless of participants’ age. Furthermore, reducing the visual and proprioceptive feedback had a greater effect on the children’s handwriting performances than on those of adults. Overall, the present study provides new insight into the contribution of the different types of sensory feedback and their interaction with handwriting development. In addition, our results on the impact of tablet surface on graphomotor execution will serve as useful pointers for improving the design of this tool for children, such as increasing the degree of friction of the screen surface.     

Naming analog clocks conceptually facilitates naming digital clocks

This study investigates how speakers of Dutch compute and produce relative time expressions. Naming digital clocks (e.g., 2:45, say "quarter to three") requires conceptual operations on the minute and hour information for the correct relative time expression. The interplay of these conceptual operations was investigated using a repetition priming paradigm. Participants named analog clocks (the primes) directly before naming digital clocks (the targets). The targets referred to the hour (e.g., 2:00), half past the hour (e.g., 2:30), or the coming hour (e.g., 2:45). The primes differed from the target in one or two hour and in five or ten minutes. Digital clock naming latencies were shorter with a five- than with a ten-min difference between prime and target, but the difference in hour had no effect. Moreover, the distance in minutes had only an effect for half past the hour and the coming hour, but not for the hour. These findings suggest that conceptual facilitation occurs when conceptual transformations are shared between prime and target in telling time.     

Tensions of Accountability: Scientists,Technicians and the Ethical Life of Data Production in Astronomy

ABSTRACT

Laboratory ethnographies have emphasized the importance of trust and accountability among scientists and technicians when working in co-presence. But what happens to their relations when data production is outsourced, widely separating scientists and technicians? In contemporary astronomy, observing has largely become a service that observatory staff members do for researchers. This has increased the efficiency of telescope use while also resulting in arrangements prone to some researchers’ dissatisfaction and a raised visibility of technicians’ work. Attending ethnographically to situated evaluations reveals that some data-using researchers and data-producing technicians typify each other as moral figures: staff observers come to be seen as objects of blame and scientists as excessively demanding users. Wherever data travel, the quality and quantity of data can serve as ethical affordances for assigning blame to staff technicians. By contrast, the moral figure of the excessively demanding data user does not travel beyond the observatory, and the social accountability of interactions that visiting astronomers experience in the observatory’s control room is confined to its situated enactment. As scientist–technician interactions have become discontinuous and fraught, moral figures and ethical accounts thus travel unevenly in the landscape of data production, and the importance of social interactions remains often unrecognized.
