Research summary

I study social development in infancy and  childhood, with special emphasis on the developmental origins of cooperation,  conflict, interpersonal relationships and psychopathology. My work has drawn  attention to infants’ early sharing and cooperation, and their abilities to  interact harmoniously with parents and peers.  I have also studied social  learning processes and interpersonal conflict in infancy.  I am a  co-investigator on the South London Child Development Study, which has followed  up a birth cohort of South London children from their mothers’ pregnancies to  adolescence.  My work has demonstrated prenatal and postnatal predictors  of the children’s attention, IQ and proclivities to violence. I am currently  leading the Cardiff Child Development Study (CCDS), a longitudinal study  supported by programme and project funding from the Medical Research Council.  The aims of the CCDS, which brings together both threads of my  research, are to chart normal social and emotional development in the first  eight years of life, with a special emphasis on the development of aggression  and prosocial behaviour, and to identify biological, cognitive and social risk  factors for children’s emotional and behavioural problems. We have identified  individual differences in infants’ anger and use of force that predict to later  physical aggressiveness and related behavioural problems. We have also shown  that parents’ speech to very young infants has long-term effects on their  children’s cognitive and language development.

I am also a  co-investigator on a large national project, Life Study, the next major birth  cohort study of the British population, which is jointly funded by the Economic  and Social Research Council and the Medical Research Council. I have been  providing specialist advice on testing infants at 6 and 12 months in an attempt  to understand the origins of developmental disorders. Previous large cohort  studies in the UK have relied on parents’ reports and have not undertaken  face-to-face assessments of infants. Several assessments I designed for the CCDS are currently being piloted for Life Study.

I teach developmental psychology, with special  emphasis on social and emotional development, developmental psychopathology and  developmental research methods.  In the past I have taught developmental  psychology and research methods to psychology students, social science  students, and trainee psychiatrists. I have co-authored a textbook in  statistics (Everitt & Hay, 1992) and co-edited textbooks on social  psychology (Fraser et al., 2000) and developmental psychopathology (Hay &  Angold, 1993; Rutter & Hay, 1994).  I am now working on a textbook on  emotional development.

Teaching summary

I teach lectures on developmental psychology to Level 2 students and research methods in developmental psychology to Level 3 students.  In the past I have   taught developmental psychology and research methods to psychology students,   social science students, and trainee psychiatrists. I have co-authored a   textbook in statistics (Everitt & Hay, 1992) and co-edited textbooks on   social psychology (Fraser et al., 2000) and developmental psychopathology (Hay   & Angold, 1993; Rutter & Hay, 1994). I am now working on a textbook on emotional development.

Undergraduate education

In 1971 I graduated with a B.A., magna cum laude, from Allegheny College, in   Meadville, Pennsylvania, USA, where I attained a liberal arts degree with a   distinction in psychology. I was elected to the academic honorary society Phi   Beta Kappa and awarded the Eugene and Mary Cease Psychology Award and the Louise   Jordan Prize.I presented the findings from my undergraduate research to   conferences sponsored by the Sigma Xi Society and to the Ohio Academy of   Science.

Postgraduate education

In 1976 I received a Ph.D. in developmental psychology from the University of   North Carolina at Chapel Hill, where I had been supported by a U.S. Public   Health Traineeship and an NICHD research assistantship. My Ph.D. thesis was   entitled 'Following their companions as a form of exploration for human   infants,’ supervised by Harriet Rheingold.

Research topics and related papers

The work on my laboratory focuses on the early developmental origins of   social behaviour, with a particular focus on early peer interaction. We have   documented that infants are capable of nonverbal interaction with their peers   from 6 months onward.

Several themes are highlighted in my current research on early development   and the impact of prenatal and postnatal experiences on children’s risk for   later emotional and behavioural problems. These include:

Prenatal and postnatal experiences may have different experiences on different domains of developmentOur longitudinal analyses of the   South London Child Development Study (SLCDS) have followed up a random sample of   children who were born in two of the most disadvantaged communities in the UK.   The SLCDS was one of the first studies to assess mothers’ mental health in   pregnancy as well as in the months post partum. Maternal depression in pregnancy   predicts behavioural problems: adolescents whose mothers were depressed in   pregnancy are four times as likely as other teenagers to show violent conduct   symptoms and/or engage in violent crime (Hay, Pawlby, Waters, Perra, &   Sharp, 2010). In contrast, post partum depression is associated in our study,   and in others, with cognitive outcomes. Adolescents whose mothers were depressed   at 3 months post partum had significantly lower IQ scores at age 16, even when   controlling for mothers’ and fathers’ IQ and many other potential confounds   (Hay, Pawlby, Waters, & Sharp, 2008). I propose that prenatal experiences   associated with the mother’s mental state influence stress reactivity and   self-regulatory systems developing before birth, whereas postnatal experiences   influence learning, memory and representation. This hypothesis is now being   tested in our new Cardiff Child Development Study (CCDS).

Prosocial skills are impaired in children with behavioural problems, but children with emotional problems may be prosocialOur studies   have shown that early sharing, cooperation, and sensitivity to other people’s   distress are almost universally shown in infancy (although these behaviours are   not characteristic of children with autism spectrum disorder and related   developmental problems). Individual differences emerge in the preschool years,   with some children becoming far less prosocial. Analyses of the South London   data set (Hay & Pawlby, 2003) and recent analyses of a study of   preschool-aged children in Cardiff (the Starting School Study; Hay, Hudson,   & Liang, in press) have shown that prosocial behaviour is negatively   associated with behavioural problems. In particular, children with symptoms of   ADHD are markedly less prosocial than other children, even when controlling for   their level of aggression and other conduct problems. In contrast, in these   samples, there is no association between prosocial behaviour and emotional   problems, and some emotionally troubled children are highly prosocial.

Precursors to aggressiveness can be detected in the first year of life Although many people think that all infants are naturally   aggressive, this is not true. Our observational studies of infants between 6 and   36 months of age have shown that many, though not all infants, try to tug away   toys from their peers, but hitting, kicking, and biting are very infrequent, and   shown by a minority of infants (e.g., Hay, Castle, & Davies, 2000). In our   new longitudinal study in Cardiff (CCDS), our observations of infants in   simulated birthday parties and their parents’ reports confirm this finding. Only   a minority of infants show precursors to aggressiveness, and these tendencies   are stable over time (Hay et al., under review), and are associated with known   risk factors for physical aggression.

Postgraduate research interests

I study social development in infancy and childhood, with special emphasis on   cooperation, conflict, interpersonal relationships and the development of   psychopathology. I am currently leading a multidisciplinary team in a 5-year   study designed to study the developmental origins of violence. Study areas   include: the development of irritability, maternal anger and infant anger, the   development of fear, fathers’ contributions to their infants’ development and   the normative rise and fall in repetitive behaviours.
