In this talk, I will describe a line of research from my lab investigating how attention is allocated in the presence of emotional stimuli. Specifically, this research uses event-related potential (ERP) components to assess the relationship between emotion and attention in the context of threat, including in the presence of inherently threatening images and in the presence of typically neutral stimuli that have been conditioned to be threatening in the context of the experiment. In addition, I will describe how neural and behavioral measures of attention to threatening stimuli can be used to elucidate individual differences in anxiety under some conditions.
