current research examines the electrophysiological
and behavioural indices of attentional
limitations over time intervals of less
than a second. The mind cannot attend
to everything at once. In my experiments
I present stimuli very rapidly (approx.
10/second) and ask human participants
to attend to one or more targets that
must be reported. The nature of the targets,
the time between targets, and the presentation
conditions are varied within and across
experiments. Interpretation of the pattern
of report accuracy and/or speed allows
me to infer the nature and duration of
processing each target receives. Electrophysiological
recordings are also taken while the participants
perform such tasks. Brain wave recordings
are time-locked to target presentation,
producing event-related potentials (ERPs).
The onset, latency, and presence/absence
of various components of the brain waves
also provide important information regarding
nature and duration of processing each
target receives. I also examine how dual-task processing limitations are modulated by the emotional immpact of the stimuli, as well as the participant's affective state and dispositional affect. I am also interested in isolating cognitive and affective predictors of individual differences in dual-task attention costs.
