The behavioral regulation skills of 6- and 12-month-old infants exposed prenatally to cigarette smoke and/or alcohol

Human and animal research has long documented the negative effects of early traumatic events on long-term development and socioemotional behavior. Yet, how and where the body stores these memories remains unclear. Current theories propose that the brain stores such memory in the subcortical limbic system. However, a clear theory of change with testable hypothesis has yet to emerge.In this paper, we review the classical Pavlovian conditioning learning tradition, along with its functional variant. Then, we review calming cycle theory, which builds upon the idea that mother/infant learning is distinct from other types of learning, requiring a new set of assumptions in light of functional Pavlovian conditioning.Calming cycle theory states that learning of behaviors associated with subcortical autonomic physiology is separate and distinct from learning of behaviors associated with cortical physiology. Mother/infant autonomic learning starts in the uterine environment via functional Pavlovian co-conditioning that is stored as conditional reflexes within the dyad's autonomic nervous systems. These reflexes are preserved transnatally as autonomic socioemotional reflexes (ASRs), which can be used to monitor mother-infant relational health. The functional Pavlovian co-conditioning mechanism can be exploited to change the physiological/behavioral reflex response. The theory provides a well established learning mechanism, a theory of change and a method of change, along with a set of hypotheses with which to test the theory. We present evidence from a randomized controlled trial with prematurely born infants and their mothers that supports calming cycle theory.

Breastfeeding Child Development

The literature reviewed in this article suggests that breastfeeding positively influences cognitive development. Studies comparing the effects of early feeding methods on cognition consistently show mental test score advantages for breastfed infants over bottlefed subjects. Also, breastfeeding may function as a buffer against adverse developmental outcomes from early traumatic events such as low birthweight or neurologic insults. It is recognized that breastmilk contains long-chain polyunsaturated fatty acids that are necessary for the normal development of the retina and cerebrum. Yet, breastfeeding may not always promote optimal development in children. Infants breastfed by mothers using alcohol or marijuana have lower scores on developmental tests. Thus, while breastfeeding has the potential for contributing to the healthy development of infants, it may also be capable of transferring toxic substances known to interfere with normal development.

How Can I Remember When "I" Wasn′t There: Long-Term Retention of Traumatic Experiences and Emergence of the Cognitive Self

In this article, we focus on two issues, namely, the nature and onset of very early personal memories, especially for traumatic events, and the role of stress in long-term retention. We begin by outlining a theory of early autobiographical memory, one whose unfolding is coincident with emergence of the cognitive self. It is argued that it is not until this self emerges that personal memories will remain viable over extended periods of time. We illustrate this with 25 cases of young children′s long-term retention of early traumatic events involving emergency room treatment. On the basis of both qualitative (case profiles) and quantitative (analysis of covariance) analyses, we conclude that (a) very young children (under the age of 2 years) retain limited memories for events which they commonly express behaviorally, (b) coherent autobiographical memories are not constructed until the child develops a cognitive sense of self (on average, at 24 months of age), (c) autobiographical memories for traumatic events are essentially no different from those for nontraumatic events, (d) stress is only related to long-term retention inasmuch as it is one variable that serves to make an event unique, and (e) like nontraumatic events, traumatic memories lose peripheral details during the retention interval and retain the central components of the event. These results are discussed both in terms of their implications for theories of early autobiographical memory as well as the ways in which we might differentiate implanted (or false) memories and authentic memories for traumatic events.
