Processing Underpinnings of Chronotype x Time-of-Day Interactions: A Study of a...
Leitão, José; Pires, Luís; Santos, Isabel; Guerrini, Chiara; Gomes, AnaChronotype and time-of-day interactions are often manifest in differences between performance at times-of-day matching the individual's chronotype (on-peak) and off-peak performance. However, it is not clear which processing variables determine whether on- or off-peak benefits/costs will occur. We hypothesized that only processes entangled by conditional automaticity (CA) would manifest (a)synchrony effects: on...
Cognitive control during a spatial Stroop task: Comparing conflict monitoring a...
Pires, Luís; Leitão, José; Guerrini, Chiara; Simões, Mário RodriguesCognitive control allows information processing and behaviour to vary adaptively from moment to moment depending on current goals. Two of the most prominent theories that have been proposed to account for the processing of cognitive control are the Conflict Monitoring Theory (CMT) and the Prediction of Response-Outcome Theory (PRO). According to both theories, the implementation of cognitive control during a tr...

Envelhecimento cognitivo e funções executivas: o papel particular da inibição
Pires, Luís; Leitão, José; Simões, Mário Rodrigues; Guerrini, ChiaraOne of the most widely studied hypotheses for cognitive ageing assumes that age-related effects can be explained by a less efficient operation of the executive functions and particularly inhibition. According to this hypothesis executive functions are more susceptible to ageing or are the first to be deteriorated with ageing. The present study examined the neuropsychological profile of young adults and older ad...
Event-Related Brain Potentials in the Study of Inhibition: Cognitive Control, S...
Pires, Luís; Leitão, José; Guerrini, Chiara; Simões, Mário RodriguesIn the previous 15 years, a variety of experimental paradigms and methods have been employed to study inhibition. In the current review, we analyze studies that have used the high temporal resolution of the event-related potential (ERP) technique to identify the temporal course of inhibition to understand the various processes that contribute to inhibition. ERP studies with a focus on normal aging are specifica...
