We talk to Dr. Daniel Sternberg, head of data at Notion Labs, about how to understand new developments in AI (artificial intelligence) like DALL-E-2 and chatgpt. Topics include the possibility for general intelligence in AI, similarities between human cognition and generative AI models, and the potential for sentient AI.

Stephanie Preston (University of Michigan) returns to the show to talk about her latest research. Why do we hoard stuff? And how can we get people to care about the consequences of all that stuff on the environment? Her research has taken her from the strategies that some rats use to hide seeds (some hide in lots of small caches, while others hoard in a single location), to the cognitive/neural/emotional mechanisms of human beings with hoarding disorder. People tend to have emotional attachments to the stuff they own, and although most of us have more stuff than we need, for those with hoarding disorder it can be overwhelming. In other recent research, Stephanie and her colleagues found individual differences in how connected people felt to the environment -- impassive people were less likely to be concerned about the destructive effects on the environment, and that politically conservative people tended to be more impassive.

Joe and Rolf talk to Dr. Aric Prather, a clinical psychiatrist at UCSF and author of the new book "The Sleep Prescription: Seven Days to Unlocking Your Best Rest" about why sleep is important, the relationship of stress to sleep, and how to tune your body and environment to get a great night's sleep.Special Guest: Aric Prather.

Is self-control at age 4 a predictor of lifelong success? Rolf & Joe look at new studies that replicate and extend Mischel's marshmallow experiments, discussing why some kids can wait longer for a bigger treat and what the test itself means.

Our guests, Dr. Sheila Macrine and Dr. Jennifer Fugate, discuss the concept of "embodied cognition" and its implications for the classroom. They argue that traditional cognitive psychology has ignored the fact that the brain is situated in the body, and that learning happens most effectively if it is connected with our body and our environment, rather than learned abstractly.

Developmental psychologist Matthew Gingo joins to discuss his research on morality and deception. Why and under what circumstances do parents and their children lie to one another? We discuss his paper entitled "What they don't know won't hurt them: Parents' judgments about lying to their adolescents", published in the Journal of Research on Adolescence (2019)

Joe and Rolf once again scry the future with bold and entirely accurate predictions about the year 2022

Joshua Miele is a blind scientist and inventor living in the Bay Area. Amongst his many initiatives is the Blind Arduino Project, where participants learn how to navigate a world of maker electronics that are really designed for the sighted. He talks to Joe and Rolf about his work to bring accessible and useful tools to the blind community. He teaches blind soldering classes, and he has worked to make braille maps easily accessible. He discusses what technology in recent years has helped the blind, and what hasn't.

In Annie Murphy Paul's new book, "The Extended Mind", the philosophical idea of our minds extending beyond the physical boundaries of the body are explored. Rolf and Joe talk to Annie about the implications of this idea, and how it might be used to improve the way we think in a number of contexts.Special Guest: Annie Murphy Paul.

The NIH Toolbox is the result of an ambitious project supported by the National Institutes of Health to develop a comprehensive, standardized, and highly accessible test battery to be used in research. Dr. Julie Hook is the Product Manager for the project and is in large part responsible for the development of the Toolkit. Rolf and Joe discuss with Julie a wide ranging set of topics related to the science of cognitive, sensory, and motor testing, including some of the core design principles and theortical considerations.
