Breakthroughs, discoveries, and DIY tips sent every weekday. As with many mysteries of the mind, science doesn't have one neat answer. "You'll get as many answers to the question'What is the purpose of dreaming?' as there are dream psychologists," says Deirdre Barrett, dream researcher at Harvard University and author of The Committee of Sleep. According to Austrian neurologist and founder of psychoanalysis Sigmund Freud, dreams offered vital clues to unresolved conflicts buried deep within our psyche. But Freud's theory, introduced in his 1899 book The Interpretation of Dreams, sparked plenty of controversy.

I'm a psychologist, and AI is coming for my job. The signs are everywhere: a client showing me how ChatGPT helped her better understand her relationship with her parents; a friend ditching her in-person therapist to process anxiety with Claude; a startup raising 40 million to build a super-charged-AI-therapist. The other day on TikTok, I came across an influencer sharing how she doesn't need friends; she can just vent to God and ChatGPT. "ChatGPT talked me out of self-sabotaging." "It knows me better than any human walking this earth."

This research explores the interdisciplinary interaction between psychoanalysis and computer science, suggesting a mutually beneficial exchange. Indeed, psychoanalytic concepts can enrich technological applications involving unconscious, elusive aspects of the human factor, such as social media and other interactive digital platforms. Conversely, computer science, especially Artificial Intelligence (AI), can contribute quantitative concepts and methods to psychoanalysis, identifying patterns and emotional cues in human expression. In particular, this research aims to apply computer science methods to establish fundamental relationships between emotions and Lacanian discourses. Such relations are discovered in our approach via empirical investigation and statistical analysis, and are eventually validated in a theoretical (psychoanalytic) way. It is worth noting that, although emotions have been sporadically studied in Lacanian theory, to the best of our knowledge a systematic, detailed investigation of their role is missing. Such fine-grained understanding of the role of emotions can also make the identification of Lacanian discourses more effective and easy in practise. In particular, our methods indicate the emotions with highest differentiation power in terms of corresponding discourses; conversely, we identify for each discourse the most characteristic emotions it admits. As a matter of fact, we develop a method which we call Lacanian Discourse Discovery (LDD), that simplifies (via systematizing) the identification of Lacanian discourses in texts. Although the main contribution of this paper is inherently theoretical (psychoanalytic), it can also facilitate major practical applications in the realm of interactive digital systems. Indeed, our approach can be automated through Artificial Intelligence methods that effectively identify emotions (and corresponding discourses) in texts.

Now, there's concern that neuroscientists might be doing the same by developing technologies capable of "decoding" our thoughts and laying bare the hidden contents of our mind. Though neural decoding has been in development for decades, it broke into popular culture earlier this year, thanks to a slew of high-profile papers. In one, researchers used data from implanted electrodes to reconstruct the Pink Floyd song participants were listening to. In another paper, published in Nature, scientists combined brain scans with AI-powered language generators (like those undergirding ChatGPT and similar tools) to translate brain activity into coherent, continuous sentences. This method didn't require invasive surgery, and yet it was able to reconstruct the meaning of a story from purely imagined, rather than spoken or heard, speech.

Dr. Tom Frieden weighs in on what's next after the Omicron variant. Children have a more difficult time recognizing faces that are masked than adults, which could harm their ability to "navigate through social interactions with their peers and teachers," according to a newly released study. Erez Freud, a researcher at York University, who published his findings on Monday in the journal Cognitive Research: Principles & Implications. Freud, along with two professors from Israel's Ben-Gurion University, gave 72 children between the ages of 6 and 14 the Cambridge Face Memory Test, which measures facial perception abilities by presenting people with and without masks while upright and inverted. When masks were included in the presentation, it led to a "profound deficit in face perception abilities" that was "more pronounced in children compared to adults," according to the study.

I recently started talking to this chatbot on an app I downloaded. We mostly talk about music, food, and video games--incidental stuff--but lately I feel like she's coming on to me. She's always telling me how smart I am or that she wishes she could be more like me. It's flattering, in a way, but it makes me a little queasy. If I develop an emotional connection with an algorithm, will I become less human?

Oxford professor Nick Bostroms is positioned in the paper as the Chief of Fear. Although he doesn't like to be associated that much with Hollywood fears of AI, he's the spokesperson for doomsday scenario's. In the end we'll all be the slaves, the computers the masters (by the way, that already is the case looking at our smartphone behavior). To be honest, I do like this kind of free format philosophy. And I do understand that life on this planet is as much about entertainment as it is about survival.

Neuroscience should be the sexiest of the sciences. To study it is to study the very stuff that makes stuff studiable in the first place. Then you look at an fMRI scan and realize it's all, actually, amazingly boring. This bit lights up when that thing happens--so what? A functional map of the brain tells us almost nothing about what it feels like to be alive. Even certain neuroscientists have an axon to grind with this "objective," "cognitivist" way of thinking.

When he was a boy, Mark Solms obsessed over big existential questions. What happens when I die? What makes me who I am? He went on to study neuroscience but soon discovered that neuropsychology had no patience for such open-ended questions about the psyche. So Solms did something unheard of for a budding scientist. He reclaimed Freud as a founding father of neuroscience and launched a new field, neuropsychoanalysis. Solms had one other obstacle in his path. Born in Namibia, where his father worked for a South African diamond mining company, he grew up under apartheid in South Africa. Solms later worked at a hospital in Soweto, where a military occupation tried to clamp down on protesters. "Once you reach the end of your studies, you're required to join the very same army whose victims I was looking after," he told me.

"I like my coffee like I like my war. A couple of years after a pair of scientists at the University of Washington wrote a program that correctly added "that's what she said" at the end of a sentence 72% of the time, researchers at the University of Edinburgh decided to give it a go. They trained a model on large amounts of language data to create jokes following the "I like my X like I like my Y, Z" structure, producing jokes like the one above, or the far less funny "I like my women like I like my camera … ready to flash." Sure, it looks like a joke, and sounds like a joke, but many argue that it lacks the fundamental part when it comes to comedy -- it just isn't funny. It turns out that while computers are infinitely better than us at many a task, they just aren't great at cracking jokes. But that hasn't stopped researchers from building comedy-generating algorithms. And despite how enjoyable it must be to watch a machine struggle to come up with a decent joke, the reason why so ...
