This study pharmacologically manipulates arousal in humans to test its impact on performance, finding that catecholaminergic enhancement shifts the arousal-performance curve while cholinergic agents do not.

The paper provides evidence for the inverted U-shaped relationship between arousal and performance in perceptual decision-making and presents a neurobiological model explaining it.

The paper uses eye-movement analysis and information theory to separate perception from report in bistable visual stimuli, showing distinct neural mechanisms for integration and differentiation.

The paper shows conflict detection in sensory input requires attention to at least one conflicting feature, while basic sensory processing occurs without attention.

The paper investigates how natural fluctuations in alertness affect cognitive control by analyzing neural and behavioral responses during a conflict task under varying alertness conditions.

The paper shows that the brain detects stimulus features but not conflict in task-irrelevant sensory input using EEG data from humans.
