Visual motion processing and perceptual decision making
The model works with n dimensions, continuous choices and any integrate-to-threshold decision model. The model has a 300ms constant motor response time added. The maximum trial length for both the experiment and model is 800ms. The model performs similarly well using 4and 8-choice decisions. The monkey response at 0% coherence may indicate ‘guess’ formulation involving non-sensory mechanisms (S...
متن کاملBrain mechanisms for perceptual and reward-related decision-making.
Phenomenological models of decision-making, including the drift-diffusion and race models, are compared with mechanistic, biologically plausible models, such as integrate-and-fire attractor neuronal network models. The attractor network models show how decision confidence is an emergent property; and make testable predictions about the neural processes (including neuronal activity and fMRI sign...
متن کاملDecision Making Logic of Visual Brain
A popular view is that the brain is making fast decisions in temporal and frontal cortices predominantly on the bases of the feedforward pathways (FF). In later stages iterations (reverberations) with delayed feedback connections (FB) may be helpful. We propose, an opposite concept, that decisions are made in single neurons from the retina to the cortex, and that FB is fast as FF, and from the ...
متن کاملNeural Oscillations and Synchronization Differentially Support Evidence Accumulation in Perceptual and Value-Based Decision Making
Organisms make two types of decisions on a regular basis. Perceptual decisions are determined by objective states of the world (e.g., melons are bigger than apples), whereas value-based decisions are determined by subjective preferences (e.g., I prefer apples to melons). Theoretical accounts suggest that both types of choice involve neural computations accumulating evidence for the choice alter...
متن کاملComparing perceptual and preferential decision making.
Perceptual and preferential decision making have been studied largely in isolation. Perceptual decisions are considered to be at a non-deliberative cognitive level and have an outside criterion that defines the quality of decisions. Preferential decisions are considered to be at a higher cognitive level and the quality of decisions depend on the decision maker's subjective goals. Besides these ...
