In the present meta-analysis, we examined the effect of cognitive training on the Executive Function (EF) of preschool children (age range: 3-6 years). We selected a final set of 32 studies from 27 papers with a total sample of 123 effect sizes. We found an overall effect of cognitive training for improving EF (g =.352; k = 123; p <.001), without significant difference between near and far transfer effects on executive domains. No significant additional outcome effects were found for behavioral- (...) and learning-related outcomes. Cognitive training programs for preschoolers are significantly more effective for developmentally at-risk children (ADHD or low socio-economic status) than for children with typical development and without risks. Other significant moderators were computerized versus non-computerized training, individual versus group sessions, and length of training. The number of sessions was not a significant moderator. This is the first demonstration of cognitive training far transfer effects among different executive processes. We discuss this result in relationship with the lower level of modularization of EFs in younger children. (shrink)

We present five studies investigating the effects of approach and avoidance behaviours when individuals do not enact them but, instead, learn that others have performed them. In Experiment 1, when participants read that a fictitious character (model) had approached a previously unknown product, they ascribed to this model a liking for the object. In contrast, they ascribed to the model a disliking for the avoided product. In Experiment 2, this result emerged, with a smaller effect size, even when it was (...) clear that the behaviours followed specific instructions from a third party. The model had been a mere executor instead of behaving autonomously. Finally, in Experiments 3, 4, and 5, we showed, with direct and indirect measures of attitudes, that reading that the model had approached vs avoided products was sufficient to create preferences in the participant for the approached one, regardless of whether it was explained that the model was a mere executor. This research highlights the largely unexplored effects of vicarious approach/avoidance behaviours. Theoretical and practical implications and possible developments of this line of research are discussed. (shrink)

Social learning plays a prominent role in shaping individual preferences. The vicarious approach-avoidance effect consists of developing a preference for attitudinal objects that have been approached over objects that have been avoided by another person (model). In two experiments (N = 448 participants), we explored how the vicarious approach-avoidance effect is affected by agency (model’s voluntary choice) and identification with the model. The results consistently revealed vicarious approach-avoidance effects in preference, as indicated by the semantic differential and the Implicit Association (...) Test. Agency increased the size of the preference assessed through the semantic differential but did not significantly impact preference in the Implicit Association Test. Identification with the model had no significant impact on the vicarious approach-avoidance effect. Theoretical and practical implications of the results are discussed. (shrink)
