Is Fear the Same Thing for a Human Being as for an Animal?

Psychiatrist Joseph Ledoux has thought about that; it’s a complex problem

Recently, we looked at consciousness from the perspective of Joseph LeDoux’s recent book, A Deep History of Ourselves (1919). Psychologist Lisa Feldman Barrett situates his work at Nature, offering an interesting qualification: LeDoux, an academic at New York University in New York City, is best known for his research on fear, and for carefully mapping the brain circuit centred on the amygdala — a knot of neurons in the medial temporal lobe. The amygdala, he showed, has a crucial role in non-conscious, defensive behaviour responses such as freezing or fleeing. His conclusion, based on the assumption that all mammalian amygdala circuits are structurally similar, was that all mammals (including humans) share these responses. He described this work in The Emotional…

Emotion Recognition Software Use Spreads While Science Is Doubted

Emotional recognition software has been coming under fire for misuse and racial bias for some time

An editor at AI Trends notes The global emotion detection and recognition market is projected to grow to $37.1 billion by 2026, up from an estimated $19.5 billion in 2020, according to a recent report from MarketsandMarkets. North America is home to the largest market. John P. Desmond, “Market for Emotion Recognition Projected to Grow as Some Question Science” at AI Trends (June 24, 2021) But the software has been coming under fire for misuse and racial bias for some time: “How people communicate anger, disgust, fear, happiness, sadness, and surprise varies substantially across cultures, situations, and even across people within a single situation,” stated the report, from a team of researchers led by Lisa Feldman Barrett, of Northeastern University,…

No, You Do Not Have a Lizard Brain Inside Your Human Brain

The “lizard brain” is part of what science used to know about the brain that ain’t so

Lisa Feldman Barrett (pictured), Northeastern University psychology prof and author of Seven and a Half Lessons About the Brain (2020), is candid about the way new research has cast doubt on old saws in science: “As a neuroscientist, I see scientific myths about the brain repeated regularly in the media and corners of academic research.” The myth she targets in a recent article at Nautilus is the “triune brain,” the idea that our brain developed and continues to function in three successive layers. First developed by neuroscientist Paul D. MacLean (1913–2007) in the 1960s and set out in more detail in his 1990 book The Triune Brain in Evolution, the triune brain theory posited three successive layers of brain: ●…

Neuroscientist: Your Brain Isn’t for Thinking, Just Surviving

Lisa Feldman Barrett hopes that her materialist perspective will help us deal with our current anxieties

Last Sunday, we featured the views of philosopher Samir Chopra, who argues that anxiety, while distressing, is a normal outcome of our human ability to see the past and the future as well as the present. A pig gets anxious when he sees that his trough is empty. But he cannot, by nature, know that he is destined for the menu at a local fast food place, let alone that all his kin have gone that way. Knowing the past and sensing the future opens up both great powers and vast avenues of anxiety for a human mind. But, in an op-ed in the New York Times, psychologist and neuroscientist Lisa Feldman Barrett (pictured), the author of Seven and a…
