The emergence of separation protest is robust under conditions of severe developmental stress in rural Bangladesh.

The response of 185 infants to their mothers' departure was assessed in a rural area of Bangladesh. Despite their poor health and nutritional status, this group of infants showed the same peak in separation protest around the end of the first year that has been documented for healthier samples in several cultural contexts; correlational analysis suggests that the healthier infants were more likely to display protest. In addition, there was an earlier rise and decline in distress at maternal departure in the first half year of life, not seen in other reports.
