Скачать или смотреть The Hidden Logic of Choice: Drift Diffusion Model

The source provides an overview of how the brain makes both trivial and complex decisions by illustrating the Drift Diffusion Model (DDM). This model explains decision-making as a process of gathering noisy evidence that is analogous to a drunkard stumbling between two walls, where hitting one wall represents the final choice. The source breaks down the DDM into three measurable components: the drift rate, which signifies the pull towards one option; boundary separation, which reflects the trade-off between speed and accuracy; and non-decision time, which accounts for basic perceptual and motor actions. Furthermore, the video highlights that this mathematical model aligns remarkably with observed neuroscientific evidence of neuron firing rates during decision-making. Lastly, the source briefly mentions alternative models, such as the linear ballistic accumulator and quantum-like models, to emphasize the dynamic nature of cognitive research into choice.
