This article examines the fundamental differences between how human children acquire values and competencies versus how current artificial intelligence systems are trained. While modern AI training relies on large datasets and software guardrails, humans learn through a combination of innate biological programming, personal experience, and essential social interaction within a community. The author argues that to achieve truly reliable, trustworthy, and human-compatible AI, developers should move beyond mere data containment and instead integrate deep learning with the collaborative, staged experiences found in developmental robotics and social species.
Marc Bekoff interviews avian biologist Dr. Louis Lefebvre about his new book exploring the remarkable intelligence and problem-solving abilities of birds. The discussion covers how bird species innovate to adapt to challenges like urbanization and how these behaviors are passed down through generations. Using an innovation quotient based on thousands of observed feeding behaviors, Lefebvre examines the convergent evolution of intelligence in both birds and primates.
>"Avoid insight washout by drawing the boundaries of delegation"
As UX researchers transition from tool operators to delegators of agentic AI, they face the risk of "insight washout," where statistical averages replace critical user nuance. To maintain professional value, researchers must strategically automate tactical drudgery while retaining human control over deep interpretation and empathetic synthesis.
* Automate routine tasks like transcription and data cleaning.
* Preserve human judgment for edge cases and emotional nuances.
* Use reclaimed time to focus on strategic decision-making.

A new study published in *Thinking & Reasoning* reveals that the ability to use logical intuition—the "smart intuitor" profile where high intelligence leads to accurate gut instincts—is a developmental milestone that matures throughout adolescence. By testing middle and high school students with probability puzzles, researchers found that while older teenagers can use deliberate thought to correct stereotypical biases, younger students lack the underlying mental strategies to override these instincts even with extra time. This suggests that true seamless logic is not immediate but rather an optimized skill built through years of academic practice and cognitive development.
Mammalian brains function through a constant balance of cooperation and competition between specialized circuits. While internal circuits cooperate, long-range competitive interactions manage limited resources and prevent excessive synchronization. This mechanism allows different brain systems to take turns shaping overall dynamics, facilitating complex cognitive processes like decision-making, attention, and memory.
This perspective article challenges the traditional view that categorization is a final stage of perception occurring after feature detection and memory retrieval. Instead, the authors propose that categorization is an integral computational strategy implemented throughout all stages of neural signal processing. By utilizing predictive feedback signals to organize feedforward processing, the brain creates a neural context that enables continuous grouping of objects, actions, or events into equivalence clusters.
Key points include:
- Categorization occurs from the beginning of signal processing rather than as an end stage.
- The role of predictive feedback in creating a neural context for organization.
- Evidence drawn from neuroanatomy, electrophysiology, and cognitive science.
- Implications for understanding neuropsychiatric disorders and future research directions.

Cognitive scientists Lisa Feldman Barrett and Earl K. Miller propose a paradigm shift in understanding brain categorization. Moving away from the traditional view that the brain compares sensory input to stored prototypes, they argue that categorization is a predictive process used to meet bodily needs through motor action plans. In this model, categories are dynamically constructed signals that shape how we perceive incoming information rather than being late-stage intellectual exercises.
Key points:
* Categorization serves as a core function for anticipating bodily needs and motor actions.
* The brain is predictive rather than reactive, preparing responses before sensory processing is complete.
* Anatomical evidence shows that feedback connections from memory to sensory regions significantly outweigh feedforward signals.
* Misalignment in these processes may contribute to conditions like depression or autism.

This study investigates whether the human brain has an organized baseline state of function that is suspended during goal-directed tasks. Researchers used positron-emission tomography (PET) to measure the oxygen extraction fraction (OEF)—the ratio of oxygen used by the brain to oxygen delivered by blood—in resting adults.
Key findings include:
1. Uniformity at Rest: Despite significant differences in blood flow and oxygen consumption between gray and white matter, the OEF remains remarkably uniform across the brain during a resting state (eyes closed, awake).
2. Defining Baseline: The researchers propose that this uniform OEF represents an equilibrium state of local neuronal activity, serving as a true physiological baseline.
3. Deactivation Patterns: Many brain regions, particularly in the visual system, consistently show decreases in activity (deactivations) during cognitive tasks.
4. Validation: By measuring the OEF at rest, the study confirms that these task-induced decreases are not merely artifacts of an undefined control state but represent a genuine drop from a stable baseline level of brain function.
The results suggest the existence of a default mode of brain function that is active when specific goal-directed behaviors are not being performed.

This paper details the reconstruction and execution of the Logic Theorist (LT), considered the first artificial intelligence program, originally created in 1955-1956. The authors built a new IPL-V interpreter in Common Lisp and faithfully reanimated LT from code transcribed from a 1963 RAND technical report. The reanimated LT successfully proved 16 of 23 theorems from Principia Mathematica, consistent with the original system's behavior. This work demonstrates "executable archaeology" as a method for understanding early AI systems, highlighting the challenges and insights gained from reconstructing and running historical code.
A new analysis of genetic studies suggests the cognitive capacity for language emerged at least 135,000 years ago, with language likely becoming a social tool around 100,000 years ago. Researchers examined genetic data from Y chromosome, mitochondrial DNA, and whole-genome studies to trace the divergence of human populations, reasoning that all languages share a common origin. The study proposes that language initially developed as an internal cognitive system before evolving into a means of social communication. Archaeological evidence of symbolic behavior around 100,000 years ago supports the idea that language played a key role in the development of modern human behavior.
