Richard Davidson & Nathan A. Fox 
Psychobiology of Affective Development (PLE: Emotion) [PDF ebook] 

Originally published in 1984, this was the first volume on this topic to appear in an emerging area of study at the time. The editors were selective in choosing their contributions to the volume to ensure that both the developmental and neuropsychological domains were well represented. One of the major goals was to foster greater contact and cross-fertilization between subdisciplines that they firmly believed should be more intimately connected. The result is this title, which can now be enjoyed in its historical context.
