Although it is well known that people's feelings can often influence what they remember, how they think, and what they do, systematic investigations of these effects are relatively new. Summarizing much of what has been learned in the past several decades, this book looks at how good and bad feelings arise, and then how they can affect thought and actions. Besides showing the often-suprising ways in which mood can shape judgments and memory, this volume examines, among other things, how emotional arousal influences the accuracy of eyewitness testimony, whether childhood traumas are repressed, and what impact people's feelings have on their susceptibility to persuasive communications.
