Human general intelligence
Performance across different cognitive tasks is often related. Which brain mechanisms help explain that shared variation and the many abilities that do not reduce to it?

Value-based decision making
A choice combines what we want, what we expect, and what we remember. How does the brain turn those inputs into one action, especially when the options are uncertain?
Cognitive control
We can switch tasks, follow a rule, and suppress a tempting response. How do brain networks coordinate that flexible control?
Metacognition
Choosing an answer and judging whether it is right are different tasks. Which brain computations produce that second judgment?
Transitive inference
Learning that A outranks B and B outranks C can let us compare A with C. How do people build and revise this knowledge?
Bilingual language control
Bilingual speakers can select and switch languages. How do control strategies adapt to conversation, competing demands and language experience?
Completed-intention aftereffects
A reminder can bring back an action that is already finished. What determines whether that memory merely interrupts us or prompts a mistaken repeat?
Mental rotation
Comparing turned objects often takes longer at larger angles. Do people rotate continuously, use discrete view changes, or recognize shape more directly?
