| Sumario: | A study was conducted to explore the control of interference to determine whether control involves a single process or multiple processes using negative priming (NP) and a directed-forgetting procedure that induces proactive interference (PI). Data were obtained from 16 adults who underwent behavioral analyses, of whom 15 also underwent imaging analyses. Findings pointed to some dissociable interference-control processes associated with NP and PI. Findings indicated that as well as interference costs in responding, other interference costs cannot be presented in problems as episodic retrieval. Findings also indicated that there are inhibitory components to NP, acting as early as primary visual cortex and possibly involving the medial dorsal thalamus as well, although NP may have some elements related to conflict during episodic retrieval. Findings are discussed in detail.
