ALWAYS UNDER CONSTRUCTION!!!
We are interested in understanding fundamental mechanisms in vision and
attention, broadly construed, as well as the impact of emotional information
cognitive processing. Currently, some of our main projects include:
Ξ A characterization of the contribution of
peripheral vision to our rich sense of the world.
We focused on analyzing performance in very simple
visual search tasks to illustrate that there is a surprisingly
large amount of information that can be successfully
extracted in parallel from peripheral vision. However,
extracting this information takes time, so analysis of the
temporal variability in these tasks allows us to identify the
underlying mechanisms of parallel peripheral vision. In this
project, we use a combination of psychophysical methods,
computational modeling, eye-tracking, and EEG.
ʘ Investigation on the relationship between distracting
stimuli and their impact on performance. We developed a
framework to help categorize different cognitive phenomena and
what each can tell us about distraction and distractor processing.
Importantly, we demonstrated that distracting stimuli are processed
fundamentally differently in “distractor-interference paradigms” (e.g., Flanker, Stroop, Simon tasks) than in paradigms where the distractor stimuli are unrelated to the task (e.g., Inattentional Blindness, Gave aversion). We use psychophysical and eye-tracking methods, as well as measures of individual differences.
Ǿ Investigation of the interaction between emotion and cognition.
We investigate the effects of emotional stimuli on cognitive tasks, like time
perception and Posner Cueing. Further, we are also interested in the effect of
our sense of agency on the interaction between emotion and cognition. Does the
illusory (or real) perception of control over experimental events changes the
way we experience and react to those events? We study these effects in
individuals who vary in their emotional profile and mood. We use psychophysical
methods, fMRI, and measures of individual differences.
Other ongoing lines of research include: the study of priming in visual search, the predictive role of the visual system, implicit learning, the role that alpha oscillations play in awareness and cognition, and mind-wandering.
