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

blue light, brain, eeg, melatonin, photosensitive retinal ganglion cells, sleep
We examine a paper that finds sleep disruption from using tablet computers (as compared to reading a book in dim light). How much should we be worried about the effects of screens on a good night's sleep?
There's good reason to believe that blue light is the main culprit -- recently discovered receptors in the eye that respond to blue light directly connect to brain areas implicated in sleep regulation. We lay out the case....

Is self-control something that we an think of as a resource that can be depleted and replenished? It's been a popular model in psychology for years, but it has come under question recently.
