Epilogue

Brian Hopkins� and Nadja Reissland

Looking back over the history of child psychology, one is struck by a dearth ofreference to the nexus between the prenatal and postnatal development. Suchwas not always the case, as witnessed in the writings of Wilhelm Preyer(1841–1897) and Arnold Gesell (1880–1961), both of them attempted to applyembryological principles of growth to ontogenetic development in general. Thesubsequent rise of behaviourism, and its close cousin, reflexology, resulted inthe depiction of the human fetus as nothing more than a ‘bundle of reflexes’, withthe consequence that an interest in prenatal development diminished among thechild psychologists. Even with the demise of behaviourism and the incursion ofthe so-called cognitive revolution, development during the 9 months prior tobirth continued to suffer from neglect. How then have we reached the point atwhich we can claim that the foundations exist for the establishment of a fetalpsychology?

To begin with, the recognition that the fetal movements under physiologicalconditions are spontaneous expressions of an inherently active nervous systemand contribute to the emergence of recognizable behavioural states before birthopened the door to the search for evidence of learning in the human fetus. Thedriving force behind such a ‘paradigm shift’ was not only the applicability of 2-Dreal-time ultrasonography, but also improvements in registering the fetal heartrate as well as more recent advances in visualizing and registering fetal beha-viour and brain activity. Up-to-date reviews of, and commentaries on, such ad-vances form a cornerstone of the Special Issue. What these contributions makeclear is that progress in the evolvement of fetal psychology is very much de-pendent on the further enhancement and integration of these research tools.

Turning from these methodological considerations to more theoretical ones,here we find the Special Issue’s other cornerstone. It is in some need of but-tressing. The fetal programming hypothesis (FPH) is particularly attractive forpromoting insights into the origins of a range of developmental disorders, in-cluding cognitive dysfunctions. The FPH, however, has not been immune fromcritical challenges (McEwen, 1998; Susser & Levin, 1999). But where fetal psy-chology needs a theoretical impulse if it is to succeed as a mature area of dis-course and research is in terms of a theory of developing brain–behaviourrelationships in the human fetus that accounts for functional continuitiesbetween the pre- and postnatal development as well as ontogenetic adaptationsconfined to existence in the uterus. Together with the FPH, a well-articulatedtheoretical scenario in this respect will enable the challenge of deriving prin-cipled methods of detecting fetuses at risk for subsequent (postnatal) disabilities.

In accordance with the FPH, there is a recent evidence from animal studiesdemonstrating the epigenetic modification of gene expression in, for example, theinfluence of maternal stress on fetal development (Hyman, 2009). The usual ca-veat of taking care in extrapolating from animal to human studies has been raisedwith such findings (Szyf, McGowan, & Meaney, 2008). Nevertheless, animalmodels of prenatal development can serve as a source of theoretical inspirationfor research with human fetuses (e.g. see Schaal, 2005).

In conclusion, research relevant to establishing fetal psychology on a firmfooting is still in its infancy. This Special Issue highlights some of the questionsand tentative solutions implicated in this endeavour. At a general level of ab-straction, it sets out the agenda for future research in addressing such issues asthe adaptive significance of developmental plasticity (that can have both negativeand positive consequences), the nature of the complex interactions between thefetus and the social environment (e.g. in terms of maternal psychological state),and the types and contexts in which fetal learning, perception and action canoccur. To use a well-worn phrase: watch this space!
