Committee report: Guidelines for human startle eyeblink electromyographic studies.
The human startle response is a sensitive, noninvasive measure of central nervous system activity that is currently used in a wide variety of research and clinical settings. In this article, we raiseExpand

The Effects of Caffeine and Directed Attention on Acoustic Startle Habituation
The present experiment tested the effects of caffeine on acoustic startle habituation during different attention tasks in which subjects either (a) attended to the acoustic startle stimulus (auditoryExpand

Emotional reactivity in nonsuicidal self-injury: divergence between self-report and startle measures.
The current study examined emotional reactivity in nonsuicidal self-injurers and noninjuring controls using self-report (the Emotional Reactivity Scale: ERS) and psychophysiological measures (theExpand

A comparison of several methods used to quantify prepulse inhibition of eyeblink responding.
Several methods of quantifying prepulse inhibition (PPI) of eyeblink responding were compared in adult volunteers. Blink-eliciting stimuli were noise bursts at 85 or 100 dB, and prepulses were alsoExpand

Extraversion, attention, and startle response reactivity
The present study investigated the impact of directed attention tasks performed by introverts and extraverts, using the brainstem startle eyeblink response as a measure of automatic reactivity.Expand

Your emotion or mine: labeling feelings alters emotional face perception—an ERP study on automatic and intentional affect labeling
Empirical evidence suggests that words are powerful regulators of emotion processing. Although a number of studies have used words as contextual cues for emotion processing, the role of what is beingExpand

Prepulse inhibition decreases as startle reactivity habituates.
In the present study, I investigated the effect of stimulus repetition on human startle eyeblink reflex inhibition (PPI) by a prepulse. Participants were assigned to one of three groups (n = 14Expand

Prepulses Reduce the Pain of Cutaneous Electrical Shocks
Objective Both the startle reflex elicited by an intense acoustic or tactile stimulus and the perceived intensity of that stimulus can be diminished by a weak “prepulse” that precedes the startlingExpand

Failure to sustain prepulse inhibition in adolescent marijuana users.
BACKGROUND Marijuana use is typically initiated during adolescence, which is a critical period for neural development. Studies have reported reductions in prepulse inhibition (PPI) among adults whoExpand
