It would also be appropriate to refer to studies related to short-term or long-term effects of deprivation and/or trauma, such as:
- Robertson and Bowlby's (1952) studies showing that maternal deprivation may cause physical, mental and emotional growth retardation
- Rutter et al.'s (2001) studies demonstrating that the consequences of deprivation vary with the severity and duration of the depriving experience, the age of the child at which the deprivation occurs and the adequacy of substitute measures such as the quality of the caretaker
- Cockett and Tripp's (1994) study on long-term attachment deprivation effects.
