Cognitive Psychology – Attention

  • multi-tasking
  • attentional distraction
  • emotion and attention
  • individual differences in attention
  • electrophysiology of attention

We cannot attend to everything at once. In my lab we investigate attention – it’s limits in dual-task situations, attentional capture and distraction, how attention and emotion interact, and individual differences in attention.

For a more complete list of recent publications, please visit my Lab website.

Individual Differences and Attention
