Movement related cortical potentials in a face naming task: Influence of the tip-of-the-tongue state

Event-related potentials in face naming and tip-of-the-tongue state: Further results

“…In the present study, the lack of differences in the amplitude of the LNW between the response categories supports the hypothesis of Buján et al (2009) and indicates that the brain activity associated with the verbal response modulates the LNW amplitude when the verbal response immediately follows the manual response. Once the responses were dissociated, the LNW would not be modulated by the verbal response.…”

“…In other words, in the present study, unlike in the previous study, the manual and verbal responses were temporally dissociated, with the aim of determining the influence of such dissociation on the LNW. This aim was based on the findings of Buján et al (2009), who demonstrated that the differences in LNW amplitude among responses were probably not only explained by the reasons given by Díaz et al (2007) but also by the differential modulation of Movement-Related Cortical Potentials on ERPs in the response categories.…”

“…In a second study, Buján et al (2009) evaluated the manual and speech Movement-Related Cortical Potentials of the same task, in a subsample of the participants involved in the previous study (Díaz et al, 2007). The results indicated that the LNW occurred in TOT at the same time as the Negative Slope related to the manual response appeared, but in KNOW and DON´T KNOW it coincided with the interval corresponding to the Speech-related Motor Potential.…”

“…Moreover, on the basis of the results obtained by Buján et al (2009), it may be expected that temporal dissociation of the manual and verbal responses, by delaying the verbal response beyond the 2 s of the EEG epoch evaluated, will lead to a reduction in the amplitude of the LNW in the KNOW and DON´T KNOW response categories, because of lack of modulation of the verbal response on LNW.…”

An event‐related potentials study of face naming: Evidence of phonological retrieval deficit in the tip‐of‐the‐tongue state

“…However, as the authors indicated, this difference might have been modulated by the cerebral activity associated with verbal‐related potentials, due to the participants having to perform two motor responses sequentially, with no delay between them; that is, they had to press a button and then say the name of the person or a specific phrase. This hypothesis was tested and later demonstrated by Buján, Lindín, and Díaz (), by evaluation of motor‐related cortical potentials (MRCPs) in a subsample of the participants in the study of Díaz et al. ().…”
