Psychobiology: Behavior from a Biological Perspective covers the problems encountered in understanding the biology of behavior. This book contains seven chapters that present a contemporary analysis of the essential features of these problems. Chapter 1 provides extensive evidence concerning the evolution of specific aspects of behavior and illustrates the genetic processes underlying the evolution of behavior. Chapter 2 presents a contemporary analysis of the problem of instinctive behavior. Chapters 3 to 7 are concerned with processes underlying behavior, including sensory processes, motivation, attention, and memory. These chapters discuss the essential issues together with contemporary facts and theories. This work will be of value to psychobiologists, neurobiologists, behaviorists, and researchers who are interested in the biological aspects of behavior.
