Cognitive Lock-In and the Power Law of Practice

MediaScience is the leading provider of lab-based media and advertising research, incorporating a range of neuro-measures including biometrics, facial expression analysis, eye tracking, EEG, and more. With state-of-the-art labs in New York, Chicago, and Austin, MediaScience is discovering actionable insights in advertising, technology, media, and consumer trends.

Dr. Duane Varan, the global authority of neuromarketing research, founded Audience Labs (formerly the Interactive Television Research Institute) during his tenure at Murdoch University in Perth, Australia, in 2001. In 2005, he launched the Beyond : 30 Project, a consortium exploring the changing media and advertising landscape, and in 2008, he was approached by Disney Media Networks to set up a dedicated custom research lab on a broader scale – and so MediaScience was born. Though he officially left Murdoch in 2015, he continues to maintain some research links with the University of South Australia and has been widely recognised for his innovative contributions to teaching and the neuromarketing industry as evidenced by a long list of awards and over 90 published academic papers in his field.

Below is an abstract from a paper Dr. Varan oversaw about Cognitive Lock-In and the Power Law of Practice from Australian Journal of Marketing.

The authors suggest that learning is an important factor in electronic environments and that efficiency resulting from learning can be modeled with the power law of practice. They show that most Web sites can be characterized by decreasing visit times and that generally those sites with the fastest learning curves show the highest rates of purchasing.
