Human subjects

Compared to other brain functions (like remembering and deciding), how the brain reflects mood is much less well understood. One reason is that there is no objective right answer to the question, "How happy are you?" Consequently, mood cannot be studied by benchmarking against percent correct on behavioral tasks. While challenging, we cannot shy away from understanding mood given that ~20\% of adults will experience a mood disorder at some point, and for ~30\%, existing treatments will be ineffective. Here, we build on work that modulates, probes, and models fluctuations in subjective happines

…stimuli, differs markedly from human decision-making, thus limiting their applicability as models of human perceptual behavior. Here we develop a new neural network, RTNet, that generates stochastic decisions and human-like response time (RT) distributions, and also reproduces all foundational features of human accuracy, RT, and confidence. To test RTNet9s ability to pr
