The book offers a unique model in an area where research is much-needed: the cognitive underpinnings, interactions and discursive effects of our evolving use of smartphones in everyday app-mediated communication, from text messages and gifs to images, video and social media apps The book gives attention to how both the particular interfaces of different apps and users' personal attributes influence the contexts and uses of smartphone communication The book includes insights from related disciplines such as media studies and sociology in an attempt to unpack the timeliest questions of our digitally mediated age This book will prove valuable for scholars and graduate students of communication, linguistics, pragmatics, media studies and sociology of mass media and will likewise engage upper-level undergraduate students
