Stop press.

Inhibitory effects on response force in the stop-signal paradigm.

The forcefulness of key press responses was measured in stop-all and selective stopping versions of the stop-signal paradigm. When stop signals were presented too late for participants to succeed in stopping their responses, response force was nonetheless reduced relative to trials in which no stop signal was presented. This effect shows that peripheral motor aspects of primary task responses c...

Contextual response time adaptation in the countermanding performance of rats.

Humans and non-human primates are known to lengthen their response time (RT) to a go signal when they occasionally must cancel their responses following a stop signal in a countermanding task as well as to adjust their RT adaptively on a trial-by-trial basis. Less is clear regarding the adaptive RT adjustments in the countermanding performance of rodents. To investigate this question, male Wist...

Perceptual Assesst"lent of F'ricative~stop Coarticulation*

The perceptual dependence of stop consonants on preceding fricatives (Mann and Repp, in press) was further investigated in two experiments employing both natural and synthetic speech. These experiments consistently replicated our original finding that listeners report more velar stops following [s]. In addition, our data confirmed earlier reports that natural fricative noises (excerpted from ut...

Reckoning the moment of reckoning in spontaneous voluntary movement.

In everyday life, movements are sometimes triggered by external sensory stimuli, like when the traffic light ahead turns from green to red and you move your foot from the gas pedal to the brake pedal in response. But many of our voluntary movements are spontaneous, meaning that they are not tied to any recent stimulus in the current sensory environment. This capacity affords us what Gold and Sh...
