Psychometric functions are often interpreted in the context of Signal Detection Theory, which
emphasizes a distinction between sensory processing and non-sensory decision rules in the …

For nearly 50 years, the dominant account of decision-making holds that noisy information is
accumulated until a fixed threshold is crossed. This account has been tested extensively …

Measuring when exactly perceptual decisions are made is crucial for defining how the
activation of specific neurons contributes to behavior. However, in traditional, nonurgent …

Embodied Choice considers action performance as a proper part of the decision making
process rather than merely as a means to report the decision. The central statement of …

A perceptual judgment is typically characterized by constructing psychometric and
chronometric functions, ie, by mapping the accuracies and reaction times of motor choices …

Standard models of perceptual decision-making postulate that a response is triggered in
reaction to stimulus presentation when the accumulated stimulus evidence reaches a …

Optimality studies and studies of decision-making in monkeys have been used to support a
model in which the decision boundaries used to evaluate evidence collapse over time. This …

The countermanding task is a standard method for assessing cognitive/inhibitory control
over action and for investigating its neural correlates. In it, the subject plans a movement and …

Existing theories of movement planning suggest that it takes time to select and prepare the
actions required to achieve a given goal. These theories often appeal to circumstances …

Neuronal activity in the frontal eye field (FEF) ranges from purely motor (related to saccade
production) to purely visual (related to stimulus presence). According to numerous studies …
