The Blog

One of the many pleasures of being a professor was feeling the need to stay on top of the research in psychology. When I first learned about the half-life of knowledge, the literature typically said it was 3-5 years in technical fields. As a retired professor, I am still a member of the American Psychological Association and subscribe to a service that delivers abstracts and open-source articles from a large number of journals. As an alumna of Harvard, I also get information from them and I have the time to peruse multiple sources. This is a pleasure most professionals don’t have, especially if they value
work-life balance.

I still love research and, when I was asked to write the blog, I enthusiastically agreed. I try to select articles based on their relevance to practitioners, but also to capture both emerging themes and important corrections. I am hopeful that, moving forward, we will have ways to enable readers to easily engage in conversations with me and each other.

Anti-dopamine parenting

This post comes from a story originally on NPR’s Morning Edition. In late June 2023, Six Things Psychologists Are Talking About posted Miotke’s “Anti-dopamine parenting can curb a kid’s craving for screens or sweets.” Here’s the highly edited transcript with some bold in the tips section:

Back when my daughter was a toddler, I would make a joke about my phone: "It's a drug for her," I'd say to my husband. "You can't even show it to her without causing a tantrum." She had the same reaction to cupcakes and ice cream at birthday parties.
