Practice Induces Function-Specific Changes in Brain Activity

Practice can have a profound effect on performance and brain activity, especially if a task can be automated. Tasks that allow for automatization typically involve repeated encoding of information that is paired with a constant response. Much remains unknown about the effects of practice on encoding and response selection in an automated task.To investigate function-specific effects of automatization we employed a variant of a Sternberg task with optimized separation of activity associated with encoding and response selection by means of m-sequences. This optimized randomized event-related design allows for model free measurement of BOLD signals over the course of practice. Brain activity was measured at six consecutive runs of practice and compared to brain activity in a novel task.Prompt reductions were found in the entire cortical network involved in encoding after a single run of practice. Changes in the network associated with response selection were less robust and were present only after the third run of practice.This study shows that automatization causes heterogeneous decreases in brain activity across functional regions that do not strictly track performance improvement. This suggests that cognitive performance is supported by a dynamic allocation of multiple resources in a distributed network. Our findings may bear importance in understanding the role of automatization in complex cognitive performance, as increased encoding efficiency in early stages of practice possibly increases the capacity to otherwise interfering information

Overcoming the objectivity of the senses: Enhancing journalism practice through Eastern philosophies

This article attempts to broaden the theoretical boundaries of journalism studies by re-examining journalism practices in the context of divisions between Western and Eastern philosophies. It looks at journalistic techniques of truth-seeking with particular emphasis on i) the ability to pick up a ‘scoop’, that is an original story; ii) interviewing as an art of inquiry, and iii) the use of statistics in supporting evidence. By so doing, the authors want not only to problematise the debates between epistemology and ontology within the boundaries of journalism studies, but also see how Eastern philosophies can help to allocate this debate in a more globalised context that can overcome the limitations set by the Enlightenment as a political project
