Parental autonomy-supportive practices and toddlers’ rule internalization: A prospective observational study

Motivational research conducted within self-determination theory suggests that autonomy-supportive (AS) parenting fosters rule internalization, while more controlling tactics hinder it. The goal of the present study is to examine how AS in a socialization context relates to toddlers’ internalization. Toddlers participated in a clean-up and a toy prohibition task at 2 and 3.5 years of age (T1: N?=?102; T2: N?=?85). Their parent’s disciplinary strategies were coded the first year. Toddlers’ committed compliance, indicative of rule internalization, was coded at both time points. After controlling for covariates and initial committed compliance, a linear regression was conducted to predict change in committed compliance over time. As expected, results reveal that parental AS strategies when toddlers were 2 years old were positively related to an improvement in committed compliance from 2 to 3.5 years of age, while controlling strategies predicted deterioration. This prospective, observational study suggests that supporting toddlers’ autonomy in socialization contexts fosters rule internalization.     

Strategy switch costs in arithmetic problem solving

Three experiments tested whether switching between strategies involves a cost. In three experiments, participants had to give approximate products to two-digit multiplication problems (e.g., 47×76). They were told which strategy to use (Experiments 1 and 2) or could choose among strategies (Experiment 3). The participants showed poorer performance when they used different strategies on two consecutive trials than when they used the same strategy. They also used the same strategy over two consecutive problems more often than they used different strategies. These effects, termed strategy switch costs, were found when the participants executed the easiest strategy and when they solved easy problems. We discuss possible processes underlying these strategy switch costs and the implications of these strategy switch costs for models of strategy choices.
