Are people indiscreet online? How much of a problem is Internet addiction? Am I addicted to the Internet? Can joining a virtual community have health benefits or costs? The Internet is transforming business, education, and maybe even ourselves. In this timely and unique text, Adam Joinson provides a clear, engaging and lively summary of the psychology of the Internet, while at the same time drawing lessons from previous technologies as diverse as the early telephone, telegraph and even radio hams. Mixing anecdote with findings from psychological studies, this book provides a clear, compelling and insightful vision of the psychology of the Internet, and the implications for the design of future technologies. It is an invaluable resource for anyone studying Internet behaviour or interested in their own or others' online behaviour.ADAM JOINSON is Lecturer at the Institute of Educational Technology at the Open University.
