Pupil-Linked Arousal Determines Variability in Perceptual Decision Making
Decision making between several alternatives is thought to involve the gradual accumulation of evidence in favor of each available choice. This process is profoundly variable even for nominally identical stimuli, yet the neuro-cognitive substrates that determine the magnitude of this variability are poorly understood. Here, we demonstrate that arousal state is a powerful determinant of variabil...
متن کاملPupil-linked arousal is driven by decision uncertainty and alters serial choice bias
While judging their sensory environments, decision-makers seem to use the uncertainty about their choices to guide adjustments of their subsequent behaviour. One possible source of these behavioural adjustments is arousal: decision uncertainty might drive the brain's arousal systems, which control global brain state and might thereby shape subsequent decision-making. Here, we measure pupil diam...
متن کاملArousal and Economic Decision Making
Previous experiments have found that subjecting participants to cognitive load leads to poorer decision making, consistent with dual-system models of behavior. Rather than taxing the cognitive system, this paper reports the results of an experiment that takes a complementary approach: arousing the emotional system. The results indicate that exposure to arousing visual stimuli as compared to neu...
متن کاملThe Phantom Decoy Effect in Perceptual Decision-making 1 RUNNING HEAD: The Phantom Decoy Effect in Perceptual Decision-making The Phantom Decoy Effect in Perceptual Decision-making
A phantom decoy is an alternative that is superior to another “target” option, but is unavailable at the time of choice. In value-based decisions involving phantom decoys (e.g., consumer choices), individuals often show increased preference for the similar, inferior target option over a non-dominated competitor alternative. Unlike value-based decisions that are driven by subjective goals, perce...
متن کاملOscillatory Network Dynamics in Perceptual Decision-Making
Synchronized oscillations of ensembles of neurons in the brain underlie human cognition and behaviors. Neuronal network oscillations can be described by the physics of coupled dynamical systems. This dissertation examines the dynamic network activities in two distinct neurocognitive networks, the salience network (SN) and the ventral temporal cortex-dorsolateral prefrontal cortex (VTC-DLPFC) ne...
