Short-term induction of assimilation and accommodation

Abstract

The dual-process model of developmental regulation distinguishes two processes of self-regulation (assimilation = tenacious goal pursuit, and accommodation = flexible goal adjustment) that depend on differing conditions, but both contribute to successful development. Four experiments were conducted to investigate whether assimilation and accommodation can be induced or at least shifted by sensorimotor and cognitive manipulations. Experiment 1 investigated the relation between body manipulation and self-regulation. It was shown that assimilation could be triggered when participants were asked to hold on to golf balls as compared to being asked to drop them. Experiment 2 showed that a semantic priming of "let go" or "hold on" via instructions influenced the processes of self-regulation. Experiment 3 and Experiment 4 investigated the role of cognitive sets (divergent thinking) and motivational processes (thinking about one's action resources) in enhancing accommodation or assimilation. As expected, accommodation was triggered by an intervention activating divergent thought, and participants were more assimilative when they thought about their action resources. In sum, the results indicate that assimilation and accommodation can be induced experimentally; they were systematically dependent on physical, cognitive, and motivational states. The implications of the findings were discussed in the light of the dual-process model.
