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)
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)
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)
