The term 'interval timing' is used to describe the processes involved in the estimation and reproduction of intervals in the seconds to hours range. Humans and other animals depend on this ability for many forms of cognitive processing, including learning, memory, and attention. Functional and Neural Mechanisms of Interval Timing is the only book that integrates across both human and animal timing and focuses on timing and time perception from both a behavioral and neural perspective. The foremost experts in the field provide neuroscientists, ethologists, and psychologists with the background needed to understand the psychophysics and neurobiology of this crucial behavior.
