How to Improve the Reliability of Aperiodic Parameter Estimates in M/EEG: A Method Comparison. [PDF]

Psychophysiology
ABSTRACT Interest in broadband aperiodic brain activity (1/f phenomenon) has increased exponentially over recent years, partly fueled by the development of tools to parameterize it (i.e., estimate its offset/intercept and exponent/slope) using the M/EEG power spectrum. Broadband aperiodic activity needs to be separated from narrowband periodic activity

Strategy or local control? Interaction of Gratton effect and proportion’s effect in the Stroop test

Vestnik of Saint Petersburg University. Psychology, 2023
Models of cognitive control contain the mechanism of the general strategy of solving a task and control of specific stimuli special mechanisms. There is an ongoing discussion as to which control is responsible for the Gratton effect and the Stroop test’s proportion effect. The Gratton effect consists in decreasing the Stroop effect after an incongruent

Now you see it, now you don't: Controlling for contingencies and stimulus repetitions eliminates the Gratton effect [PDF]

Acta Psychologica, 2011
The Gratton (or sequential congruency) effect is the finding that conflict effects (e.g., Stroop and Eriksen flanker effects) are larger following congruent trials relative to incongruent trials. The standard account given for this is that a cognitive control mechanism detects conflict when it occurs and adapts to this conflict on the following trial ...

Investigating the effects of pre-stimulus cortical oscillatory activity on behavior

NeuroImage, 2020
Rhythmic brain activity may reflect a functional mechanism that facilitates cortical processing and dynamic interareal interactions and thereby give rise to complex behavior.

The Role of Subjective Experiences in Conflict Tasks: A Review

Psychologica Belgica, 2021
Cognitive control research is concerned with the question how we install adaptive behaviour in the case of (cognitive) conflict. In this review we focus on the role that awareness of this conflict plays in our ability to exert cognitive control.

Eye blink correction: a test on the preservation of common ERP components using a regression based technique [PDF]

PeerJ, 2013
Eye blinks are a pervasive problem in electroencephalography research as they contaminate the brain signal. This paper tests the merits of a software tool employing the regression-based Gratton method that claims to remove the detrimental effects of the ...

Questioning conflict adaptation: proportion congruent and Gratton effects reconsidered [PDF]

Psychonomic Bulletin & Review, 2013
Conflict adaptation is one of the most popular ideas in cognitive psychology. It purports to explain a wide range of data, including both brain and behavioral data from the proportion congruent and Gratton paradigms. However, in recent years, many concerns about the viability of this account have been raised.

Metacognition and cognitive control : behavioural adaptation requires conflict experience [PDF]

, 2018
Cognitive control allows adapting our behaviour to improve performance. A behavioural signature of cognitive control is the Gratton effect. This effect is observed in conflict tasks and indicates smaller congruency effects after incongruent trials than ...

Conflict adaptation is predicted by the cognitive, but not the affective alexithymia dimension

Frontiers in Psychology, 2014
Stimulus-induced response conflict (e.g., in Simon or Stroop tasks) is often reduced after conflict trials—the Gratton effect. It is generally assumed that this effect is due to a strengthening of the representation of the current intention or goal ...

The O-Na and Mg-Al Anticorrelations in Turn-Off and early Subgiants in Globular Clusters [PDF]

, 2000
High dispersion spectra (R>40,000) for a quite large number of stars at the main sequence turn-off and at the base of the subgiant branch in NGC6397 and NGC6752 were obtained with the UVES on Kueyen (VLT UT2). The [Fe/H] values we found are -2.03+/-0.02+/
