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.

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 development
Our 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 prosocial
Our 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.
