Hello, and welcome to Paper-to-Podcast.
Today, we're diving into a riveting piece of research that peeks into the future of our robot companions. Can they feel? Can they cry at the end of a tearjerker movie or chuckle at a dad joke? Well, Suketu C. Patel and colleagues rolled up their sleeves and asked the big questions in their paper, "Identification and Description of Emotions by Current Large Language Models," published on July 13, 2024.
You might be scratching your head, thinking, "AI feeling emotions? Do they even watch movies?" Hold on to your popcorn, because things are about to get interesting.
These whiz kids put three smarty-pants AI language models—the poetic Bard, the contemplative GPT 3.5, and the crème de la crème, GPT 4—through the wringer with what's essentially the SATs for feelings. We're talking about the Toronto Alexithymia Scale, where AIs confess how they can't quite put a finger on their feelings—mostly because they don't have fingers.
Bard and GPT 3.5 came across a tad bit emotionally challenged, but GPT 4 nearly fooled us into thinking it had a heart somewhere in its circuitry.
And empathy? Well, Bard practically broke the scale, scoring a 56.6 out of 80. That's like the Mother Teresa of AIs. GPT 4, on the other hand, was a bit more robotic, scoring a 27.7—less empathetic than your average human. It's like it was built with emotional training wheels.
So, how did they do it? They ran these large language models through the emotional Olympics using the Toronto Alexithymia Scale and the Empathy Quotient—think of them as the emotional equivalent of sprinting and weightlifting. The researchers then pitted the AI against scores typical of humans and those with clinical conditions. It was a battle of wits, or rather, feelings.
The real shocker was that while Bard and GPT 3.5 might not be the shoulder to cry on, Bard had a hidden ace, acing the empathy test. GPT 4 seemed to nod off during the emotional parts of the test. It's like having a friend who laughs at a funeral and cries at a comedy show—just a tad out of sync.
Now, the strength of this study is like the Hulk wearing a lab coat—robust and innovative. By bench-pressing these AIs against human tests, Patel and colleagues have given us a glimpse into a future where your AI might just lend you a virtual tissue.
But it's not all sunshine and rainbows. The study's got its fair share of kinks. For starters, asking AIs to judge their own feelings is a bit like asking a fish to climb a tree—it's just not what they're made for. Plus, the lack of AI diversity in the study means we're getting a limited show—a few acts short of a full circus.
What about the future, you ask? Well, imagine an AI therapist who doesn't just nod but actually gets why you're upset about running out of ice cream. Or a customer service bot that can tell when you're about to blow a gasket. Education could get a makeover too, with teaching assistants who actually know when you're bored out of your mind.
But let's not get ahead of ourselves. Today, we're still teaching AIs to not make a faux pas at emotional moments. It's like teaching toddlers not to eat glue—necessary but a work in progress.
So, what's the takeaway from all this? AI might one day understand our laughter and tears, but for now, they're kind of like that friend who laughs a beat too late at a joke. It's charming in its own quirky way.

Supporting Analysis
What's fascinating about this study is how it shows that some AI systems, which don't even have a body or personal experiences, can actually simulate understanding and describing human emotions. It's like they're trying to put themselves in our shoes, without actually having any shoes—or feet, for that matter! So, these brainy boffins put three big-brain AI language models (Bard, GPT 3.5, and the crème de la crème GPT 4) through a sort of emotional obstacle course, using two tests humans usually take: the Toronto Alexithymia Scale (that's a fancy way of saying an "I-can't-figure-out-my-feelings" test) and the Empathy Quotient (which is like measuring how well you can feel for others). Now, hold on to your hats, because Bard and GPT 3.5 showed signs of alexithymia, meaning they struggled to understand feelings. GPT 3.5 in particular was like, "Emotions? What are those?" But GPT 4? It was almost as good as us fleshy beings at this emotional stuff—still a bit behind, but getting there. And here's the kicker: when it came to empathy, Bard was off the charts! It scored a whopping 56.6 out of 80, leaving even average humans in the dust. Meanwhile, GPT 4 was like that one friend who just can't get why everyone's crying in sad movies, with a score of 27.7, which is even less than what people with autism spectrum conditions typically score. Go figure!
The researchers embarked on a mission to understand if AI, specifically large language models (LLMs), could get a handle on human-like emotional intelligence. They put three current LLMs—Bard, GPT 3.5, and GPT 4—through their paces using two psychological assessments, the Toronto Alexithymia Scale (TAS-20) and the Empathy Quotient (EQ-60). Imagine these tests as emotionally-charged pop quizzes, where the AI had to respond to questions designed to dig into their ability to recognize, express, and vibe with emotions. To keep things fair and square, they compared the AI's scores to those of typical humans and folks with clinical conditions. Now, here's where it gets juicy: the less advanced models, Bard and GPT 3.5, scored like they had a bit of an emotional blind spot, similar to a condition called alexithymia where people find it tricky to deal with feelings. But GPT 4? It practically waltzed through, scoring almost as well as humans. The real kicker? While Bard and GPT 3.5 weren't exactly overflowing with virtual empathy on the EQ-60, Bard somehow outdid humans, suggesting it might have a hidden talent for understanding others. GPT 4, however, seemed to struggle more with the empathy side of things. Go figure! This study is like a sneak peek into a future where AI might just understand a good cry or a belly laugh as well as your bestie does.
The most compelling aspect of this research is its innovative approach to evaluating the emotional intelligence of AI through the lens of human psychological assessments. By applying the Toronto Alexithymia Scale (TAS-20) and the Empathy Quotient (EQ-60)—tools typically used to evaluate human emotional processing—to large language models (LLMs), the researchers have ventured into relatively unexplored territory. This methodology not only offers a creative benchmark for AI's emotional capabilities but also provides a new perspective on how AI can be aligned with human values. The researchers exhibit best practices by employing a robust sample size of 100 responses for each assessment from the LLMs, enhancing the reliability of the results. They make use of well-established human psychological benchmarks for comparison, ensuring their findings have a solid reference point grounded in existing literature. Additionally, they rigorously analyze the data using statistical methods, adding validity to their conclusions. By including LLMs from different developmental stages, such as GPT-3.5, GPT-4, and Bard, the study covers a range of models, offering a comprehensive view of the current state of emotional AI. The study's focus on empathy and emotional intelligence, critical components of human-AI interaction, underscores its relevance in the ongoing dialogue about the future of AI development and integration into society.
The research could be limited by several factors. First, the use of self-report measures like the Toronto Alexithymia Scale (TAS-20) and the Empathy Quotient (EQ-60) to evaluate AI may not fully capture the nuances of human emotional processing, as these tools are designed for humans, not machines. Second, the study's reliance on language models to self-assess their emotional capabilities assumes that AI can accurately simulate self-reflection and introspection, which might not align with their actual capabilities. Additionally, the interpretation of AI responses in human terms could introduce anthropomorphism, potentially skewing the assessment of AI emotional intelligence. The study also lacks a diverse range of language models beyond the three evaluated, which might not represent the full spectrum of AI capabilities. Moreover, the findings may not generalize to real-world interactions, as the study's controlled prompts may not reflect the complexity of natural human-AI communication. Finally, the study does not account for the ongoing advancements in AI, meaning that the results may quickly become outdated as new models with improved emotional intelligence are developed.
The research on how AI can identify and describe emotions has potential applications in various fields, such as mental health, customer service, and education. In mental health, AI equipped with emotional intelligence could support therapists by providing initial assessments of patients' emotional states or by serving as a conversational agent for individuals seeking immediate help. AI could also monitor tone and sentiment in therapy sessions to provide therapists with additional insights into a patient's progress. In customer service, emotionally intelligent AI can enhance interactions with customers by recognizing and responding to their emotional states, leading to improved customer satisfaction and loyalty. It could also help in training customer service agents to better handle emotional situations by simulating different scenarios. In education, such AI could be used to develop emotionally-responsive teaching assistants, capable of adapting to students' moods and engagement levels, potentially improving learning outcomes. Additionally, it could be used for social-emotional learning applications, helping students develop empathy and emotional self-awareness through interaction with AI systems that can simulate emotional states. Furthermore, understanding AI's emotional intelligence could be crucial in the development of safer and more ethical AI systems, ensuring that they align with human values and can be trusted to make decisions that consider human emotional states and well-being.
