The mechanism of dishabituation [PDF]

open access: yesFrontiers in Integrative Neuroscience, 2014
The dual-process theory of habituation attributes dishabituation, an increase in responding to a habituated stimulus after an interpolated deviant, to sensitization, a change in arousal. Our previous investigations into elicitation and habituation of the electrodermal orienting reflex (OR) showed that dishabituation is independent of sensitization for ...
