Abstract: Interpersonal touch is known to influence human communication and emotion. An important system for interpersonal touch is the C-tactile (CT) system, which is activated by a soft stroke on hairy skin with a velocity of… read more here.

Abstract: Increasing the intensity of auditory stimuli has been shown to produce faster simple reaction times (RTs). Typical explanations for this effect involve earlier detection of the more intense stimulus; however, these explanations fail to consider… read more here.

DOI: 10.1016/j.jneumeth.2020.108813
Abstract: BACKGROUND Advances in the control of transcranial magnetic stimulation (TMS) have enabled greater randomisation of stimulus intensity. It is unclear if such randomisation improves assessments of corticospinal excitability. NEW METHOD We recorded the amplitude of… read more here.

DOI: 10.1111/psyp.13266
Abstract: The human startle eyeblink response can be inhibited by a change in the stimulus environment briefly before the startling stimulus; both stimulus presentation (prepulse) and cessation of background sound (gap) can result in startle inhibition.… read more here.
