Publication: A broadband acoustic stimulus is more likely than a pure tone to elicit a startle reflex and prepared movements

PDF  In order to be able to confidently assert that any RT speeding following a startling acoustic stimulus (SAS) is the result of activation in subcortical areas related to the startle reflex, a reliable indication that a startle reflex actually occurred is required. While the eye-blink response is typically used…

Publication: Startle activation is additive with voluntary cortical activation irrespective of stimulus modality

  PDF    This paper investigated whether an additive model of activation or a horse-race model would be a better fit for data showing that reaction times are facilitated to a greater degree than would be expected when a startling stimulus presented after the typical “go” signal. Abstract: When a startling acoustic…
