A Groundbreaking Classic on Young Child Development
Format: Paperback
This first volume of John Bowlby's trilogy on Attachment and Loss expands and builds upon an article he published in 1958 in the International Journal of Psycho-Analysis titled "The Nature of the Child's Tie to His Mother", which is perhaps a more telling title than that of the book itself. Attachment, as a technical term in behavioural biology, is first used in describing instinctive mother-following behaviours of young mammals and birds (first observed and reported in delightful accounts by the Austrian ethologist Konrad Lorenz in the 1930's).
By comparing data collected during and after the Second World War by childcare workers and researchers in U.K. and North America, Bowlby found a striking common pattern of distressed behaviours among young children between the ages of one and three when separated from mother for an extended period: first in Protest, then Despair and finally Detachment - a psychopathological state when a child becomes socially uninitiated and withdrawn, even to his returning mother. Bowlby then postulates that physical proximity to a mother-figure is essential to a child's development of cognitive capacities, especially during a sensitive period around six months to two years after birth. Attachment behaviours, like those of young mammals and birds, are present in the human baby too. This has since led to a blossoming of research activities in development psychology and psychoanalysis, as well as neurophysiology recently, which supplies much fresh evidence about the young brain and its phenomenal maturing in the first two years. Attachment theory has since contributed significantly to understanding of our own selves, informed the age-old philosophical debate on nature or nurture, and brought our attention to fundamental issues in child-rearing such as sensitive periods of development, the difference between attachment (conducive to security) and dependence (symptomatic of insecurity), the distinction between anxiety from separation and fear of the unfamiliar, etc.
This new edition is a timely reprint of a classic account of attachment theory as formulated by the originator. While primarily an academic work, with a few chapters deemed more for an academic jury (about Freud and instinctive behaviours, etc.), it is mostly very readable, and certainly captivating to those with access to young babies, of whose behaviours are given an enlightening perspective. This volume focuses on attachment, with subsequent volumes on its loss in temporary and permanent terms respectively.

Couples Therapy for Domestic Violence
Format: Hardcover
Very helpful for students, clinicians, and researchers. Great information on understanding domestic violence from a systemic perspective. Excellent outline and explanation of the treatment model and how to implement it with couples and in group formats. This is the only model that offers clinicians like me a clear map to comprehensive treatment services for couples/partners presenting with intimate partner violence / domestic violence. I just purchased 2 more copies for staff interested in implementing the model. A criminal justice professional read my copy and stated: "This is treatment. This is what we need, especially for couples looking at reconciliation."

Smaller than expected
Format: Hardcover
For a book this costly, I expected it to be thicker than volume. That said, there are some great ideas in here and I will probably edit this review when I have finished reading!
