Recent research has revealed a striking tendency in young children to imitate even causally irrelevant actions, a phenomenon dubbed 'over-imitation'. To investigate whether children develop beyond this, we allowed both adults and children to witness either a child or adult model performing goal-relevant and goal-irrelevant actions to extract a reward from a transparent puzzle box. Surprisingly, copying of irrelevant actions increased with age, with the adults performing the task with less efficiency than the children. Participants of all ages were more likely to perform the irrelevant actions performed by an adult model, than by a child model. These results suggest that people may become more imitative as they mature, whilst selectively copying particular models with a high level of fidelity. We suggest that this combination of faithful copying and selectivity underwrites the powerful social learning necessary for the level of cultural transmission on which our species depends.

ObjectivesAs the number of people living beyond cancer treatment has increased, supportive post-treatment interventions have become increasingly important. The present study investigates whether participation in the Maggie’s ‘Where Now?’ post-cancer support programme is associated with improvements in healthy eating, quality of life, self-efficacy (confidence) or cancer worry.MethodsIn a pre–post design, 88 people who had completed cancer treatment and were enrolled in the 7-week ‘Where Now?’ programme at Maggie’s centres across the UK rated their diet, activity, quality of life, self-efficacy and cancer worries before and after programme participation. Programme content was coded to identify the techniques used to create change (‘behaviour change techniques’).ResultsProgramme participation was associated with significant improvements in general self-efficacy (p=0.01), self-efficacy about engaging in physical activity (p<0.01), quality of life (p<0.01) and cancer worry (p=0.04) but not with changes in healthy eating (p=0.23).ConclusionParticipation in the ‘Where Now?’ programme is associated with significant improvements in several key psychological outcomes in people living beyond cancer. The techniques most commonly used in the programme to create change were giving participants instructions about how to perform a particular behaviour, encouraging problemsolving to overcome barriers and setting goals.
