There is ample evidence that motor actions are stored in terms of, and controlled by, the sensory effects that these actions produce. At present it is unclear, though, whether action control is governed by intended sensory changes (e.g., the transition from darkness to brightness when switching on a light) or only by intended sensory end states (e.g., the light being on). The present study explored the role of sensory changes for action control. To address this issue, participants engaged in a spatial tracking task. We show that performance is determined by the compatibility between motor patterns and subsequent changes of a controlled stimulus, while the intended end state of the stimulus remains constant. Spatial compatibility increases performance even when perceptual changes of spatial features are not the primary target of control. These results suggest that intended transitions of stimulation have the potential to bias motor actions. We consider these results as an important step toward integrating closed-loop regulation approaches and ideomotor approaches of action control. (PsycINFO Database Record
Giving a dishonest response to a question entails cognitive conflict due to an initial activation of the truthful response. Following conflict monitoring theory, dishonest responding could therefore elicit transient and sustained control adaptation processes to mitigate such conflict, and the current experiments take on the scope and specificity of such conflict adaptation in dishonesty. Transient adaptation reduces differences between honest and dishonest responding following a recent dishonest response. Sustained adaptation has a similar behavioral signature but is driven by the overall frequency of dishonest responding. Both types of adaptation to recent and frequent dishonest responses have been separately documented, leaving open whether control processes in dishonest responding can flexibly adapt to transient and sustained conflict signals of dishonest and other actions. This was the goal of the present experiments which studied (dis)honest responding to autobiographical yes/no questions. Experiment 1 showed robust transient adaptation to recent dishonest responses whereas sustained control adaptation failed to exert an influence on behavior. It further revealed that transient effects may create a spurious impression of sustained adaptation in typical experimental settings. Experiments 2 and 3 examined whether dishonest responding can profit from transient and sustained adaption processes triggered by other behavioral conflicts. This was clearly not the case: Dishonest responding adapted markedly to recent (dis)honest responses but not to any context of other conflicts. These findings indicate that control adaptation in dishonest responding is strong but surprisingly focused and they point to a potential trade-off between transient and sustained adaptation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
