From the earliest months of life, we rely on faces to help us navigate the world. They tell us who’s safe, who’s familiar, and whether they’re paying attention to us. But do our responses to faces develop gradually as our brains mature? Or are we born prewired to lock onto the human face. In this episode of Under the Cortex, cognitive scientists Rebecca Saxe of MIT and Heather Kosakowski of Harvard University join host Scott Sleek to discuss their groundbreaking findings, published in Current Directions in Psychological Science, about the development of the brain’s face-processing network.

Why do we avoid retracing our steps—even when it helps us reach our goals faster? In this episode of Under the Cortex, host Özge Gürcanlı Fischer-Baum speaks with Kristine Cho and Clayton Critcher from the University of California, Berkeley about their latest research on doubling-back aversion: the tendency to resist more efficient paths if they require undoing prior effort.

Across four studies involving performance tasks and virtual navigation, Kristine finds that people often choose less efficient strategies simply to avoid feeling like their past actions were a waste. This aversion, while related to the sunk-cost fallacy, has its own unique psychological fingerprint.

Tune in to learn how our perceptions of effort, progress, and meaning can lead us astray—even when we know better.

Why do familiar experiences sometimes feel like they happened longer ago than they actually did?

In this episode of Under the Cortex, host Özge Gürcanlı Fischer-Baum speaks with Brynn Sherman from the University of Pennsylvania about her recent study published in Psychological Science, the flagship journal of the Association for Psychological Science. Sherman's research uncovers a surprising illusion: repeated experiences, which are more vividly remembered, are often perceived as having occurred further in the past than they did.

Through a series of experiments, Sherman and her colleague Yousif demonstrate that this distortion in time perception is both robust and consistent, shedding light on how our memories can mislead us about the timing of events. Tune in to explore the mechanisms behind this illusion and its implications for our understanding of memory and time.
