Attentional startle modulation has been found to be modality specific in continuous performance tasks (CPTs) and modality nonspecific in trial-structured tasks. Experiment 1 investigated whether attentional blink modulation in a CPT would change if a trial structure was imposed. Participants performed a visual CPT either continuously (CONT), or during brief(More)
Selective sensitization has been proposed as an alternative explanation for enhanced responding to animal fear-relevant stimuli--snakes and spiders--during extinction of Pavlovian fear conditioning. The current study sought to replicate the phenomenon using a shock workup procedure as the sensitizing manipulation and to extend it to interpersonal and(More)
Startle reflex eliciting stimuli presented at the onset of the go signal in a simple forewarned reaction time (RT) task (at a SOA of 0 ms) elicit larger blink reflexes than do stimuli presented later (e.g., at a SOA of 150 ms) or during inter trial intervals. The present study investigated whether this facilitation is affected by attention to the go signal(More)
