CogNation is a podcast by Rolf Nelson and Joe Hardy, two cognitive psychologists interested in the future of brain science and technology. We explore relevant topics in the areas of cognitive science, technology, AI, and philosophy. Although we dabble with dystopian implications of new technologies (such as the impending robopocalypse), we are led by our curiosity and try to keep it light and fun.

A connectome is a representation of every connection between neurons in the brain. Recent brain-slicing technology, in addition to image recognition tools, has begun to make this science-fiction idea become a reality. Rolf and Joe discuss the recent publication of the largest completed connectome to date, that of the fruit fly drosophilia. The database for the connectome is publicly available, and includes huge amounts of data about every one of the approximately 25,000 neurons mapped to date.

How do people behave in a pandemic? Joshua Ackerman of the University of Michigan talks about how we alter our behavior in the face of pathogens from the perspective of social and evolutionary psychology. A repertoire of responses (such as avoidance) referred to as the "behavioral immune system" is discussed as a way for humans to avoid pathogens BEFORE our biochemical immune system encounters them.

David Sobel, a developmental psychologist from Brown University, talks to us about the importance of play in learning. He has recently been collaborating with researchers around the country to investigate how children interact with exhibits in childrens' museums. One recent finding we discuss is that parent-child interaction styles can have a strong influence on what children learn.

conscious will, consciousness, free will, libet, neuroscience, philosophy, schurger
Guest Dr. Aaron Schurger talks to us about his research on the meaning of the "readiness potential", which has been referred to as "the brain signature of the will". Although this neural signal was already famous from research in the 1960s, it was Benjamin Libet's infamous experiments in the 1980s that proportedly showed that the readiness potential preceded an act of free will by a few hundred milliseconds. More recently (in press), Dr. Schurger and his colleagues have convincingly demonstrated that the readiness potential is not in fact predictive of an act of free will, but instead comes from a lack of a proper experimental control.

Dr. Erick Gallun joins us today to talk about the latest in audiology research, and how it can be applied to help those with a range of hearing problems. His research has focused on rehabilitation with Veteran's Association (VA) patients. Rapid-response medical care and an understanding of how hearing is affected by brain damage are critical areas in need of research. Advances in portable computing have made widespread assessment possible, and Virtual Reality applications show promise for cost-effective and standardized assessment.

David Wulff, author of the comprehensive "Psychology of Religion: Classic and Contemporary", talks with us today about some of the issues that psychologists grapple with in studying religion. How can a researcher take a fair and unbiased approach to a topic so fraught with issues of personal belief and faith? How important is belief anyway -- must one sacrifice the intellect to engage in religious practice? David discusses his recent research; his measure of religious tendencies, called the "Faith Q-Sort", has been used internationally to understand how religion manifests differently across individuals
