Temporal brain dynamics of multiple object processing: the flexibility of individuation. [PDF]
PLoS ONE, 2011 The ability to process concurrently multiple visual objects is fundamental for a coherent perception of the world. A core component of this ability is the simultaneous individuation of multiple objects. Many studies have addressed the mechanism of object

Psychophysiology, Volume 60, Issue 12, December 2023., 2023 Abstract Singleton distractors may inadvertently capture attention, interfering with the task at hand. The underlying neural mechanisms of how we prevent or handle distractor interference remain elusive. Here, we varied the type of salient distractor introduced in a visual search task: the distractor could be defined in the same (shape) dimension as ...

Perceptual grouping and visual enumeration. [PDF]
PLoS ONE, 2012 We used lateralized Event-Related Potential (ERP) measures - the N2pc and CDA/SPCN components - to assess the role of grouping by target similarity during enumeration.

Mechanisms of spatial contextual cueing in younger and older adults
Psychophysiology, Volume 60, Issue 11, November 2023., 2023 Abstract The contextual cueing effect is the phenomenon observed when response time (RT) becomes faster in visual search in repeated context compared with a new one. In the present study, we explored whether the mechanisms involved in the effect are age dependent.

Estimating statistical power for ERP studies using the auditory N1, Tb, and P2 components
Psychophysiology, Volume 60, Issue 11, November 2023., 2023 Abstract The N1, Tb, and P2 components of the event‐related potential (ERP) are thought to reflect the sequential processing of auditory stimuli in the human brain. Despite their extensive use in biological, cognitive, and clinical neuroscience, there are no guidelines for how to appropriately power ERP studies using these components.

Handgrip Based Action Information Modulates Attentional Selection: An ERP Study
Frontiers in Human Neuroscience, 2021 Prior work shows that the possibility of action to an object (visual affordance) facilitates attentional deployment. We sought to investigate the neural mechanisms underlying this modulation of attention by examining ERPs to target objects that were ...

Electrophysiological correlates of amnestic mild cognitive impairment in a simon task. [PDF]
PLoS ONE, 2013 Amnestic mild cognitive impairment (aMCI) represents a prodromal stage of Alzheimer`s disease (AD), especially when additional cognitive domains are affected (Petersen et al., 2009).

Fast detection of covert visuospatial attention using hybrid N2pc and SSVEP features [PDF]
, 2016 ObjectiveDetecting the shift of covert visuospatial attention (CVSA) is vital for gaze-independent brain-computer interfaces (BCIs), which might be the only communication approach for severely disabled patients who cannot move their eyes.

Facilitation or disengagement? Attention bias in facial affect processing after short-term violent video game exposure. [PDF]
PLoS ONE, 2017 Previous research has been inconsistent on whether violent video games exert positive and/or negative effects on cognition. In particular, attentional bias in facial affect processing after violent video game exposure continues to be controversial.
