Reinforcement learning, conditioning, and the brain: Successes and challenges
Dec 01, 2009; ... The field of reinforcement learning has greatly influenced the neuroscientific study of conditioning. This article provides an introduction to reinforcement learning followed by an examination of the successes and challenges using reinforcement learning to understand the neural bases of ...
Aging and the neuroeconomics of decision making: A review
Dec 01, 2009; ... Neuroeconomics refers to a combination of paradigms derived from neuroscience, psychology, and economics for the study of decision making and is an area that has received considerable scientific attention in the recent literature.

Emotion and motor preparation: A transcranial magnetic stimulation study of corticospinal motor tract excitability
Dec 01, 2009; ... In the present study, we examined whether preparing motor responses under different emotional conditions alters motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation delivered to the motor cortex. Analyses revealed three findings: (1) Reaction times were expedited during ...
Affective processing within 1/10th of a second: High arousal is necessary for early facilitative processing of negative but not positive words
Dec 01, 2009; ... Lexical decisions to high- and low-arousal negative words and to low-arousal neutral and positive words were examined in an event-related potentials (ERP) study. Reaction times to positive and high-arousal negative words were shorter than those to neutral (low-arousal) words, whereas those to ...
Eye-movement assessment of the time course in facial expression recognition: Neurophysiological implications
Dec 01, 2009; ... Happy, surprised, disgusted, angry, sad, fearful, and neutral faces were presented extrafoveally, with fixations on faces allowed or not. The faces were preceded by a cue word that designated the face to be saccaded in a two-alternative forced-choice discrimination task (2AFC; Experiments 1 and ...
