Are our childhood memories lost or locked? Breakthroughs, discoveries, and DIY tips sent six days a week. Was it a birthday party? Even though little kids remember plenty, most of us lose access to key memories as we get older. It's something scientists call childhood amnesia. We explore just that in a recent episode of the Ask Us Anything podcast, delving into the science behind why our brains forget our earliest memories. 's Ask Us Anything podcast (as well as our written series of the same name) answers your most outlandish, mind-burning questions--from the everyday things you've always wondered to the bizarre things you never thought to ask.

Obtaining data in the medical field is challenging, making the adoption of AI technology within the space slow and high-risk. We evaluate whether we can overcome this obstacle with synthetic data generated by large language models (LLMs). In particular, we use GPT-4 and Claude 3 Opus to create agents that simulate adults with varying profiles, childhood memories, and attachment styles. These agents participate in simulated Adult Attachment Interviews (AAI), and we use their responses to train models for predicting their underlying attachment styles. We evaluate our models using a transcript dataset from 9 humans who underwent the same interview protocol, analyzed and labeled by mental health professionals. Our findings indicate that training the models using only synthetic data achieves performance comparable to training the models on human data. Additionally, while the raw embeddings from synthetic answers occupy a distinct space compared to those from real human responses, the introduction of unlabeled human data and a simple standardization allows for a closer alignment of these representations. This adjustment is supported by qualitative analyses and is reflected in the enhanced predictive accuracy of the standardized embeddings.

From getting lost in the supermarket to going on the rocking horse at playschool, memories from before the age of five are few and far between for most people. This is due to'childhood amnesia', which refers to the inability of people to remember anything from before the age of of around three and a half. During childhood, brains are more limber, which means they are able to absorb lots of information in a small space of time. However, parts of the brains that retain this information are still under construction, scientists say. From birth until our early teens, essential circuitry in the brain is still being laid down, as electric pathways become lined with fatty tissues to become more conductive, meaning we are able to retain these memories.
