Digital media are sensory-rich, multimodal, and often highly interactive. An extensive collection of theories and models within the field of media psychology assume the multimodal nature of media stimuli, yet there is current ambiguity as to the independent contributions of visual and auditory content to message complexity and to resource availability in the human processing system. In this article, we argue that explicating the concepts of perceptual and cognitive load can create progress toward a deeper understanding of modality-specific effects in media processing. In addition, we report findings from an experiment showing that perceptual load leads to modality-specific reductions in resource availability, whereas cognitive load leads to a modality-general reduction in resource availability. We conclude with a brief discussion regarding the critical importance of separating modality-specific forms of load in an increasingly multisensory media environment.

Social Media Platforms

With the advent of popular social media platforms, news journalism has been forced to re-evaluate its relation to its audience. This applies also for public service media that increasingly have to prove its utility through audience ratings. This ethnographic study explores a particular project, the development of ‘concept bible’ for the Finnish Broadcasting Company YLE’s online news; it is an attempt to solve these challenges through new journalistic practices. The study introduces the concept of ‘nuanced universality’, which means that audience groups’ different kinds of needs are taken into account on news production in order to strengthen all people’s ability to be part of society. On a more general level, the article claims that despite its commercial origins, audience segmentation can be transformed into a method that helps revise public service media principles into practices suitable for the digital media environment.

Climate change raises the stakes of human communication to the existential level of the species and the planet. This article presents an empirical study of how users make sense of climate change as they traverse the contemporary digital media environment. Departing from a baseline survey and drawing on the tradition of reception analysis, focus groups of different ages and with various political and religious affiliations identified distinctive themes, narratives, and arguments regarding the natural environment as represented and received across different media. Climate change appears out of scale – incommensurable not only with established media formats and genres but also with common frames of human cognition and communication. In conclusion, the article addresses climate change from the perspective of human rights and social justice, under the recent heading of climate justice.

News organizations have adapted in various ways to a digital media environment dominated by algorithmic gatekeepers such as search engines and social networks. This article dissects a campaign to actively shape that environment led by professional fact-checking organizations. We trace the development of the Share the Facts “widget,” a device designed to give fact-checks greater purchase in algorithmically governed media networks by driving adoption of a new data standard called ClaimReview. We show how “structured journalism” gave journalists a language for the social and technical challenges involved, and how this infrastructural technology mediates between fact-checkers, audiences, and platform companies. We argue that this standard-setting initiative exhibits both promotional and disciplining facets, offering greater distribution and impact to journalists while also defining their work in specific ways. Crucially, in this case, this disciplining influence reflects internal professional-institutional agendas in an emerging subfield of journalism as much as the demands of platform companies.

Cognitive load theory describes learning in terms of a processing system when all too often working memory is overloaded and learning is impeded. Measuring cognitive load is an important component of research in the area of information processing. The design, delivery, and administration of an instrument, as well as its reliability and validity are discussed as a solution to the measurement of cognitive load. A nine-point subjective rating scale ranging from very, very low (1) to very, very high (9) measures cognitive load, defined as the mental effort needed to complete a task. It is a replica of the instrument used by Paas (1992) and Paas and van Merriënboer (1994). The measurement instrument can be used both on paper and on the Web.
