Can a person's tastes in art, music, literature, cinema, sport, humour or other fields be changed through online activity? This article explores that question by comparing recent research findings in the areas of neuroplasticity and flow. Neuroplasticity, also known as brain plasticity, is the idea that the human brain can change its structure and function through thought and activity, even into old age (Doidge). The second concept - flow - comes from the field of psychology, and refers to a deeply satisfying state of focused attention that people sometimes experience while engaging in an enjoyable activity such as browsing the Web (Csikszentmihalyi, Flow). Research into the experiences of web users, conducted from these two different perspectives, reveal interesting connections to the acquisition of taste and opportunities for further investigation.
