#ICML #cognition #GrowAI We spent 2 years carefully curated every single experiment (i.e. object permanence, A-not-B task, visual cliff task) in this dataset (total: 1503 classic experiments spanning 12 core cognitive concepts). We spent another year to get 230 MLLMs evaluated

First, MLLMs exhibit a reversed developmental trajectory 📉 compared to humans 📈: they perform better on "higher-level" abilities, sometimes comparable to or even surpassing humans, yet struggle with "lower-level" abilities 🙀, which humans typically develop these "lower-level"

#embodied All forms of biological intelligence are grounded movements🏃‍♂️ muscles & motor neurons 🧠 emerge before visual cortex & rods & cones in eyes 👁️ Building monocular better-than-mocap-studio #video2motion is our critical step towards human embodied intelligence.

7) The result is astonishing 😱 All models - either they become totally illusory or they become completely short-cutted. None of the models is even close to core knowledge. No models are able to get both the manipulation tasks and the control tasks right at the same time,

Started with this old man, Jean Piaget, developmental psychology has become a formal discipline with generations of dedicated scientists and over a century of sustained, yet fruitful, curious endeavors. We first built our CoreCognition framework leveraging Piaget's four-stage

2) The topology of internal cognitive representation of MLLMs is akin to human, suggesting "cognition" as a natural kind. Having 1503 individual cognitive experiments spanning 12 core cognitive concepts on 230 models allows us to interrogate the topology of internal cognitive

Living in the AI world, all classic cognitive experiments from developmental psychology literature are instantiated as cognitive prototypes. Our cognitive scientists purchase real-world equipments and manually set up physical lab-setting environments to acquire media materials

4) 🧐 🧐 Would Core Knowledge Emerge from Pure Scaling? ‼️‼️‼️Nope‼️‼️‼️ By applying linear regression to the performance data of 230 models with different model sizes & training data sizes, we quantify the scaling effect as the slope of the resulting regression line. The
