The review is divided into 4 groups of studies that suggest that (a) young infants detect contingencies unrelated to their behavior; (b) infants detect contingencies involving their behavior; (c) the study of contingency is(More)
Neural responses to facial expressions of basic emotions examined with functional Magnetic Resonance Imaging: Specificity and laterality issues Chronometry and specificity of stages of processing of facial expressions Processing of emotional expression in individuals who are depressed or have a history of alcohol abuse
Twenty-seven female undergraduates completed three tasks: (1) feel four emotions (happiness, sadness, anger, peacefulness); (2) express these emotions, without trying to feel them; and (3) feel and express clearly these four emotions.
