Three main topics are covered in this book, namely, learning, memory, and perception. The first section consists of seven papers and is devoted entirely to the learning of motor skills. The papers summarize the current state of perceptual- motor learning in general and highlight specific topics of interest to the informed reader. The second section is divided between movement memory and perception. In recent years there has been a decline in the popularity of movement memory as a research topic. However, some recent advances in cognitive science, and parallel distributed processing in particular, may now provide the basis for a renewed interest. The topic of perception never enjoyed the popularity that motor skill learning and/or memory for movement did. However there is now a clearer understanding of the perceptual processes and invariances that affect how we perceive the world. Others, like the renewed interest in signal detection theory and quantal reaction time, serve notice that the perceptual part of perceptual motor-skills is here to stay.
