Research Interests

As of 2009 I have now begun a new project investigating the developmental origins of moral judgement in young children.

My recent focus has been on the development of goal-directed behaviour in children, by which I mean behaviour motivated by knowledge of and desire for an action’s consequences. Such goal-directedness has only been demonstrated with any certainly by manipulating the value of an action’s outcome and detecting a consequent change in the tendency to perform the action. I have pioneered the application of this method in infants and toddlers (Kenward et al., in press). The results are surprising and are currently causing me to question the widespread and intuitive assumption that infants are motivated to act because they expect and desire the consequences of their actions. In related work, however, I have demonstrated that 10-month-olds do expect the outcome of their actions (Kenward, under review), indicating a possible disconnection between infants’ knowledge and their ability to use such knowledge to motivate action. Other infant work includes studies of gaze following (Gredebäck et al., in press) and imitation (ongoing).

My doctoral work focussed on the development of tool use and manufacture in juvenile New Caledonian crows. I demonstrated that the basic skills arise primarily through interplay of inherited tendencies and individual learning, although social learning also plays a role (Kenward et al., 2005a; Kenward et al., 2006). I have also studied the laterality of tool use (Weir et al., 2004), proposed a hypothesis to explain its evolution (Kenward et al., submitted-b), studied the ecology of the species (Kenward et al., 2004a), and contributed to several reviews of crow tool use (Kacelnik et al., 2006; Kacelnik et al., 2004).

Other previous work has included the theoretical study of the evolution of animal communication using neural network models of signal receivers (Kenward et al. 2004b), and the development of an outdoor Skinner box for studying learning in wild squirrel populations (Kenward et al., 2005b).
